ABOUT THIS PROSPECTUS SUPPLEMENT

This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part is the accompanying prospectus, which is part of a registration statement that we filed with the SEC using a “shelf” registration process. The accompanying prospectus describes the general terms of the securities that may be offered pursuant to the accompanying prospectus and the general manner in which those securities will be offered, some of which may not apply to this offering. This prospectus supplement and the information incorporated by reference in this prospectus supplement supplements, updates and amends the information contained in the accompanying prospectus.

Before buying any of the securities offered by this prospectus supplement, you should carefully read both this prospectus supplement and the accompanying prospectus, together with all of the information incorporated by reference in this prospectus supplement, as well as the additional information described under the heading “Where You Can Find More Information” and “Information Incorporated by Reference.” These documents contain important information that you should consider when making your investment decision. We have filed or incorporated by reference exhibits to the registration statement of which this prospectus supplement forms a part. You should read the exhibits carefully for provisions that may be important to you.

To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or in any document incorporated by reference in this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement, provided that if any statement in one of these documents is inconsistent with a statement in another document having a later date—for example, a document incorporated by reference in this prospectus supplement—the statement in the document having the later date modifies or supersedes the earlier statement.

The information contained in this prospectus supplement, the accompanying prospectus or any document incorporated by reference in this prospectus supplement is accurate only as of their respective dates, regardless of the time of delivery of this prospectus supplement, the accompanying prospectus or the documents incorporated by reference in this prospectus supplement or in the accompanying prospectus or the sale of any securities. Our business, financial condition, results of operations and prospects may have changed materially since those dates.

Neither we nor the underwriters have authorized anyone to provide you with information that is different from that contained or incorporated by reference in this prospectus supplement, the accompanying prospectus, or any free writing prospectus we may authorize to be delivered or made available to you. Neither we nor the underwriters take responsibility for, or provide assurance as to the reliability of, any other information that others may give you. This prospectus supplement does not constitute an offer to sell or the solicitation of an offer to buy any securities other than the securities described in this prospectus supplement or an offer to sell or the solicitation of an offer to buy such securities in any circumstances in which such offer or solicitation is unlawful.

For investors outside the United States: Neither we nor the underwriters have taken any action that would permit the offering or possession or distribution of this prospectus supplement in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus supplement must inform themselves about, and observe any restrictions relating to, the offering of the securities described herein and the distribution of this prospectus supplement outside the United States.

Unless otherwise indicated or the context otherwise requires, (i) all references to the “company,” “we,” “our” or “us” or similar terms refer to Immatics N.V., together with its subsidiaries, including Immatics Biotechnologies GmbH and Immatics US, Inc., and (ii) references to “Immatics” refer solely to Immatics N.V. Immatics N.V. is a Dutch public limited liability company (naamloze vennootschap) incorporated on March 10, 2020 and the holding company of Immatics Biotechnologies GmbH, a German biopharmaceutical company incorporated in 2000 focused on the development of T cell receptor-based immunotherapies for the treatment of cancer. Immatics Biotechnologies GmbH holds all material assets and conducts all business activities and operations of Immatics N.V.

Settlement Cycle

It is expected that delivery of the ordinary shares will be made against payment therefor on or about the date of delivery specified on the cover page of this prospectus supplement, which is the second business day following the date of pricing of the ordinary shares (this settlement cycle being referred to as “T+2”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the ordinary shares prior to the business day preceding the date of delivery will be required, by virtue of the fact that the ordinary shares initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

Trademarks

We own various trademark registrations and applications, and unregistered trademarks, including Immatics^®, XPRESIDENT^®, ACTengine^®, ACTallo^®, ACTolog^®, XCEPTOR^®, TCER^®, AbsQuant^®, IMADetect^® and our corporate logo. All other trade names, trademarks and service marks of other companies appearing in this prospectus supplement are the property of their respective owners. Solely for convenience, the trademarks and trade names in this prospectus supplement may be referred to without the ^® and ^™ symbols, but such references should not be construed as any indicator that their respective owners will not assert, to the fullest extent under applicable law, their rights thereto. We do not intend to use or display other companies’ trademarks and trade names to imply a relationship with, or endorsement or sponsorship of us by, any other companies.

Presentation of Financial Information

Our consolidated financial statements are presented in euros and have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). None of the consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). The terms “dollar,” “USD” or “$” refer to the U.S. dollar and the term “euro,” “EUR” or “€” refer to the euro, unless otherwise indicated. The exchange rate used in this prospectus supplement for conversion between U.S. dollars and euros is based on the ECB euro reference exchange rate published by the European Central Bank, as of June 30, 2024, unless otherwise indicated. We have made rounding adjustments to some of the figures included in this prospectus supplement. Accordingly, any numerical discrepancies in any table between totals and sums of the amounts listed are due to rounding.

Market and Industry Data

This prospectus supplement contains industry, market and competitive position data that are based on general and industry publications, surveys and studies conducted by third parties, some of which may not be publicly available, and our own internal estimates and research. Third-party publications, surveys and studies generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. While we are not aware of any misstatements regarding such third-party publications, surveys and studies, industry, market and competitive position data involve risks and uncertainties and are subject to change based on various factors, including those identified in the “Risk Factors” section of this prospectus supplement and in the documents incorporated by reference in this prospectus supplement.

RISK FACTORS

Investing in our securities involves risk. Before making a decision to invest in our securities, you should carefully consider the following risks and those included in our Annual Report on Form 20-F for the year ended December 31, 2023, and any updates to those risk factors in our reports on Form 6-K incorporated by reference in this prospectus supplement, together with all of the other information appearing or incorporated by reference in this prospectus supplement and the accompanying prospectus, in light of your particular investment objectives and financial circumstances. Although we discuss key risks in our discussion of risk factors, new risks may emerge in the future, which may prove to be significant. We cannot predict future risks or estimate the extent to which they may affect our business, results of operations, financial condition and prospects.

Risks Related to this Offering

The issuance of ordinary shares in connection with the exercise of warrants will dilute the ownership interest of the holders of our ordinary shares and may materially affect the trading price of our ordinary shares.

As of June 30, 2024, we had outstanding 7,187,500 warrants to purchase an equivalent number of our ordinary shares at an exercise price of $11.50 per ordinary share. To the extent that warrant holders elect to exercise their warrants, substantial amounts of our ordinary shares may be issued in the future. We cannot quantify the number of ordinary shares that will be issued in connection with the exercise, if any. However, the issuance of ordinary shares pursuant to such exercise could result in substantial dilution of the ownership interests of holders of our ordinary shares and could materially affect the trading price of our ordinary shares.

You will experience immediate and substantial dilution in the book value of your investment.

If you purchase our securities in this offering, you will experience immediate dilution in an amount equal to the difference between the public offering price and our net tangible book value per share after this offering. See “Dilution.”

Future sales, or the possibility of future sales, of a substantial number of our ordinary shares could adversely affect the price of our ordinary shares and dilute shareholders.

Future sales of a substantial number of our ordinary shares, or the perception that such sales will occur, could cause a decline in the market price of our ordinary shares. If our existing shareholders sell substantial amounts of ordinary shares in the public market, or the market perceives that such sales may occur, the market price of our ordinary shares and our ability to raise capital through an issue of equity securities in the future could be adversely affected.

Moreover, we have registered on registration statements on Form F-3 for the sale of shares held by certain of our shareholders and have registered on registration statements on Form S-8 all ordinary shares that we may issue under our equity incentive plan. As a result, these shares can be freely sold in the public market upon issuance, subject to restrictions applicable to affiliates. If these additional shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of our ordinary shares could decline.

If we sell ordinary shares, convertible securities or other equity securities, existing shareholders may be diluted by such sales, and in certain cases new investors could gain rights superior to those of our existing shareholders. We are currently party to a sales agreement with Leerink Partners LLC, pursuant to which we may sell our ordinary shares from time to time through an “at-the-market” equity offering program. We have filed a prospectus supplement with the SEC registering the offer and sale of our ordinary shares having an aggregate offering price of $150 million under the program. Any sales of our ordinary shares, or the perception that such sales could occur, could have a negative impact on the trading price of our ordinary shares.

We have broad discretion in the use of the net proceeds from this offering, and we may not use them effectively.

We currently intend to use the net proceeds from this offering as described in “Use of Proceeds.” However, our board of directors and our management retain broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our ordinary shares. Our failure to apply these funds effectively could result in financial losses, which could have a material adverse effect on our business, results of operations, financial condition and prospects.

S-6

If a United States person is treated as owning at least 10% of our ordinary shares, such United States person may be subject to adverse U.S. federal income tax consequences.

For U.S. federal income tax purposes, if a United States person is treated as owning (directly, indirectly or constructively) 10% or more of our stock by vote or value, such U.S. holder will be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group (if any). Because our group includes at least one U.S. subsidiary, our non-U.S. subsidiaries and any non-U.S. subsidiaries we form or acquire in the future will generally be treated as controlled foreign corporations.

A United States shareholder of a controlled foreign corporation will be required to report annually and include in its U.S. federal taxable income its pro rata share of “subpart F income,” “global intangible low-taxed income” and investments in U.S. property by the controlled foreign corporation, regardless of whether it makes any distributions of that income. Special rules, however, apply to United States persons that are partnerships or other pass-through entities. Certain deductions and credits for foreign income taxes paid or accrued by the controlled foreign corporation may be allowed to a corporate United States shareholder, but will not be allowed to an individual United States shareholder.

There can be no assurance that we will furnish to any United States shareholder the information required to comply with the obligations applicable to a United States shareholder in respect of controlled foreign corporations. Failure to comply with these obligations may subject a United States shareholder of a controlled foreign corporation to significant monetary penalties and may prevent the statute of limitations for assessments with respect to its U.S. federal income tax return for the year for which reporting was due from starting. Beneficial owners of 10% or more of our ordinary shares that are United States persons should consult their tax advisors regarding the potential application of these rules to their investment in our ordinary shares.

There is a significant risk that we will be a passive foreign investment company, or PFIC, for our current or future taxable years, which could result in adverse U.S. federal income tax consequences for U.S. investors in our ordinary shares.

In general, a non-U.S. corporation is a PFIC for any taxable year in which either (i) 75% or more of its gross income consists of “passive income” or (ii) 50% or more of the average quarterly value of its assets consist of assets that produce, or are held for the production of, “passive income.” For purposes of these calculations, a non-U.S. corporation is treated as if it holds a proportionate share of the assets of, and receives directly its proportionate share of the income of, any other corporation in which it directly or indirectly owns at least 25%, by value, of the shares of such other corporation. Passive income generally includes interest, dividends, certain non-active rents and royalties (other than certain rents and royalties derived in an active conduct of a trade or business), and capital gains. Cash is generally a passive asset for these purposes. In addition, goodwill (the value of which may be determined by reference to the excess of the sum of the corporation’s market capitalization and liabilities over the value of its assets) is generally characterized as an active asset to the extent it is attributable to activities that produce active income.

We hold a substantial amount of cash and other passive assets. In addition, our PFIC status for the current and any future taxable year may depend, in large part, on the market price of our ordinary shares from time to time. Our market capitalization has been volatile. Accordingly, to the extent that the value of our non-passive assets is determined by reference to our market capitalization, there is a significant risk that we may be a PFIC for our current taxable year and future taxable years. However, such determination can only be made after the end of the taxable year.

If we were a PFIC for any taxable year during which a U.S. holder owns our ordinary shares, certain adverse U.S. federal income tax consequences could apply to such U.S. holder. See “Taxation—Material U.S. Federal Income Tax Considerations for U.S. Holders—Passive Foreign Investment Company Rules” below.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the documents incorporated by reference in this prospectus supplement contain statements that constitute forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”). All statements other than statements of historical facts, including statements regarding our future results of operations and financial position, business and commercial strategy, potential market opportunities, products and product candidates, research pipeline, ongoing and planned preclinical studies and clinical trials, regulatory submissions and approvals, research and development costs, timing and likelihood of success, as well as plans and objectives of management for future operations, are forward-looking statements. Many of the forward-looking statements contained in this prospectus supplement can be identified by the use of forward-looking words such as “anticipate,” “believe,” “could,” “expect,” “should,” “plan,” “intend,” “estimate,” “will” and “potential,” among others.

Forward-looking statements are based on our management’s beliefs and assumptions and on information available to our management at the time such statements are made. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those identified in the “Risk Factors” section of this prospectus supplement and in the documents incorporated by reference in this prospectus supplement. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements, whether as a result of any new information, future events, changed circumstances or otherwise. You should read this prospectus supplement, the documents incorporated by reference in this prospectus supplement and the documents that we have filed as exhibits to the registration statement of which this prospectus supplement is a part completely and with the understanding that our actual future results may be materially different from what we expect.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of such statements, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

S-8

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $   million (or $   million if the underwriters’ option to purchase additional shares is exercised in full), after deducting the underwriting discount and estimated offering expenses payable by us.

We intend to use the net proceeds from this offering to fund the continued research and development of our pipeline, the manufacturing, production and, if approved, commercialization of our product candidates and for working capital and other general corporate purposes.

Our expected use of the net proceeds from this offering represents our current intentions based on our present plans and business condition, which could change as our plans and business conditions evolve. The amounts and timing of our actual use of the net proceeds from this offering will vary depending on numerous factors. As a result, we cannot predict with certainty all of the particular uses for any net proceeds to be received or the amounts that we will actually spend on the uses set forth above. Our board of directors and our management retains broad discretion in the application of the net proceeds from this offering.

Pending the use of the proceeds from this offering, we intend to invest the net proceeds in a variety of capital preservation instruments, which may include all or a combination of short-term and long-term interest-bearing instruments, investment-grade securities, and direct or guaranteed obligations of the U.S. government. We cannot predict whether the proceeds invested will yield a favorable return.

CAPITALIZATION

The following table sets forth our cash and cash equivalents, shareholders’ equity and capitalization as of June 30, 2024:

You should read this table in conjunction with our consolidated financial statements, including the notes thereto, incorporated by reference in this prospectus supplement.

S-10

DILUTION

Net tangible book value per ordinary share is determined by dividing our total assets, less intangible assets, less total liabilities by the number of our ordinary shares outstanding.

Our historical net tangible book value as of June 30, 2024 was €386.3 million (or $413.5 million), or €3.75 (or $4.01) per ordinary share. After giving effect to this offering (assuming no exercise of the underwriters’ option to purchase additional shares) and after deducting the underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2023 would have been €   million (or $   million) and our as adjusted net tangible book value per ordinary share as of June 30, 2024 would have been €   (or $  ) per ordinary share, representing an immediate increase of €   (or $  ) per ordinary share. If you purchase our securities in this offering, you will experience immediate dilution of €   (or $  ) per ordinary share, which is the difference between the public offering price and our as adjusted net tangible book value per ordinary share.

If the underwriters’ option to purchase additional shares is exercised in full, the as adjusted net tangible book value per ordinary share after this offering would increase to €   million (or $   million). This represents an immediate increase in net tangible book value of €   (or $  ) per ordinary share to existing shareholders and an immediate dilution of €   (or $  ) per ordinary share to investors in this offering.

To the extent that any outstanding warrants are exercised, any outstanding options under our share-based compensation plans are exercised, new options are issued under our share-based compensation plans or we issue additional ordinary shares in the future, there will be further dilution to investors participating in this offering.

S-11

TAXATION

Material U.S. Federal Income Tax Considerations for U.S. Holders

In the opinion of Davis Polk & Wardwell LLP, the following is a description of the material U.S. federal income tax consequences to the U.S. Holders, as defined below, of owning and disposing of our ordinary shares. It does not describe all tax considerations that may be relevant to a particular person’s decision to acquire ordinary shares.

This discussion applies only to a U.S. Holder that acquires ordinary shares registered for offer and sale pursuant to this prospectus supplement and holds ordinary shares as capital assets for U.S. federal income tax purposes (generally, property held for investment). In addition, it does not describe any tax consequences other than U.S. federal income tax consequences, including state and local tax consequences and estate tax consequences, and does not describe all of the U.S. federal income tax consequences that may be relevant in light of the U.S. Holder’s particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended (the “Code”) known as the Medicare contribution tax and tax consequences applicable to U.S. Holders subject to special rules, such as:

If an entity or arrangement that is classified as a partnership for U.S. federal income tax purposes holds ordinary shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding ordinary shares and partners in such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of owning and disposing of the ordinary shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury regulations, and the income tax treaty between Germany and the United States (the “Treaty”), all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

A “U.S. Holder” is a beneficial owner of our ordinary shares who, for U.S. federal income tax purposes, is eligible for the benefits of the Treaty and who is:

Certain Treasury regulations (the “Foreign Tax Credit Regulations”) may in some circumstances prohibit a U.S. person from claiming a foreign tax credit with respect to certain non-U.S. taxes that are not creditable under applicable income tax treaties. The U.S. Internal Revenue Service (the “IRS”) has released notices which indicate

S-12

that the Treasury Department and the IRS are considering amendments to the Foreign Tax Credit Regulations and provide temporary relief from certain of their provisions until such time as the IRS issues a subsequent notice or other guidance withdrawing or modifying the temporary relief (or any later date specified in the relevant notice or guidance). The rules governing the calculation and timing of foreign tax credits and the deduction of foreign taxes are complex and depend upon a U.S. Holder’s particular circumstances. Accordingly, U.S. investors that are not eligible for Treaty benefits should consult their tax advisors regarding the creditability or deductibility of any non-U.S. taxes imposed on dividends on, or dispositions of, ordinary shares. This discussion does not apply to investors in this special situation.

U.S. Holders should consult their tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of the ordinary shares in their particular circumstances.

Taxation of Distributions

Subject to the discussion under “—Passive Foreign Investment Company Rules” below, distributions (if any) paid on ordinary shares, other than certain pro rata distributions of ordinary shares, will generally be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, we expect that distributions generally will be reported to U.S. Holders as dividends. Dividends paid to certain non-corporate U.S. Holders may be eligible for taxation as “qualified dividend income” and therefore, subject to applicable limitations, may be taxable at long-term capital gain rates. Dividends may constitute qualified dividend income if (a) the ordinary shares with respect to which the dividends are paid are listed on Nasdaq or are otherwise considered “readily tradable” on an established securities market for U.S. federal income tax purposes or we are eligible for benefits under the Treaty and (b) we are not a PFIC in the year in which the dividend is paid or the prior taxable year. However, there can be no assurance that our ordinary shares will remain listed or otherwise be considered readily tradable on an established securities market in the future, nor (as discussed under “Passive Foreign Investment Company Rules” below) that we will not be a PFIC for any future taxable year. U.S. Holders should consult their tax advisors regarding the availability of the reduced tax rate on dividends in their particular circumstances.

As described below under “—Material Dutch Tax Considerations” and “—Material German Tax Considerations,” it is expected that any dividends we pay to a U.S. Holder will be subject to German withholding tax (and will not be subject to Dutch withholding tax). The amount of a dividend will include any amounts withheld in respect of German income taxes. The amount of the dividend will be treated as foreign-source dividend income to U.S. Holders and will not be eligible for a dividends-received deduction generally available to U.S. corporations under the Code. Dividends will be included in a U.S. Holder’s income on the date of the U.S. Holder’s receipt of the dividend. The amount of any dividend income paid in euros will be the U.S. dollar amount calculated by reference to the exchange rate in effect on the date of actual or constructive receipt, regardless of whether the payment is in fact converted into U.S. dollars at that time. If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder should not be required to recognize foreign currency gain or loss in respect of the dividend income. A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.

Subject to applicable limitations, some of which vary depending upon the U.S. Holder’s particular circumstances, and the discussion below regarding the Foreign Tax Credit Regulations, German taxes withheld from dividends on ordinary shares (at a rate not exceeding the rate provided by the Treaty, in the case of a U.S. Holder eligible for a reduced rate under the Treaty) will be creditable against the U.S. Holder’s U.S. federal income tax liability. As discussed under “—Material German Tax Considerations” below, Germany requires special procedures to be followed by U.S. Holders eligible for a reduced rate under the Treaty to obtain the benefit of such reduced rate. The rules governing foreign tax credits are complex. For example, the Foreign Tax Credit Regulations provide that, in the absence of an election to apply the benefits of an applicable income tax treaty, in order for foreign income taxes (including foreign withholding taxes treated as income taxes) to be creditable, the relevant foreign jurisdiction’s income tax rules must be consistent with certain U.S. federal income tax principles, and we have not determined whether the German income tax system meets these requirements. However, under the temporary relief in the notice described above, certain of the requirements for making this determination would not apply until such time as the IRS withdraws or modifies this temporary relief (or any later date specified in the relevant notice or guidance). Whether the IRS will withdraw this relief for 2024 or future years is inherently uncertain. U.S. Holders should

S-13

consult their tax advisors regarding the creditability of any German taxes in their particular circumstances. In lieu of claiming a foreign tax credit, a U.S. Holder may be able to elect to deduct foreign taxes, such as the German withholding tax, in computing its taxable income, subject to generally applicable limitations under U.S. law. An election to deduct otherwise creditable non-U.S. taxes instead of claiming foreign tax credits applies to all creditable non-U.S. taxes paid or accrued in the taxable year.

Sale or Other Disposition of Ordinary Shares

Subject to the discussion under “—Passive Foreign Investment Company Rules” below, gain or loss realized by a U.S. Holder on the sale or other disposition of ordinary shares will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder’s holding period for such ordinary shares was more than one year as of the date of the sale or other disposition. The amount of the gain or loss will equal the difference between the U.S. Holder’s tax basis in the ordinary shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. Long-term capital gain recognized by a non-corporate U.S. Holder is subject to U.S. federal income tax at rates lower than the rates applicable to ordinary income and short-term capital gains, while short-term capital gains are subject to U.S. federal income tax at the rates applicable to ordinary income. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The deductibility of capital losses is subject to various limitations.

Passive Foreign Investment Company Rules

Under the Code, we will be a PFIC for any taxable year in which either (i) 75% or more of our gross income consists of “passive income” or (ii) 50% or more of the average quarterly value of our assets consist of assets that produce, or are held for the production of, “passive income.” For purposes of the above calculations, we will be treated as if we hold our proportionate share of the assets of, and receive directly our proportionate share of the income of, any other corporation in which we directly or indirectly own at least 25%, by value, of the shares of such corporation. Passive income generally includes interest, dividends, certain non-active rents and royalties (other than certain rents and royalties derived in an active conduct of a trade or business), and capital gains. Cash is generally a passive asset for these purposes. In addition, intangible assets, such as intellectual property and goodwill (the value of which may be determined by reference to the excess of the sum of a corporation’s market capitalization and liabilities over the value of its assets) are generally characterized as an active asset to the extent it is attributable to activities that produce active income.

Whether we will be a PFIC in the current or any future year is uncertain because, among other things, (i) we currently own, and likely will continue to own, a substantial amount of passive assets, including cash, (ii) the valuation of our assets that generate non-passive income for PFIC purposes, including our intangible assets, is uncertain and may be determined in substantial part by our market capitalization, which may vary substantially over time and (iii) the timing of our recognition of active income for U.S. federal income tax purposes, which may differ from the timing of the recognition of such income for financial accounting purposes, may result in our recognizing lesser amounts of active income for U.S. federal income tax purposes in certain taxable years. In particular, our market capitalization has been volatile. Accordingly, to the extent that the value of our non-passive assets is determined by reference to our market capitalization, there is a significant risk that we may be a PFIC for our current taxable year and possibly future taxable years. However, such determination can only be made after the end of the taxable year.

If we are a PFIC for any year during which a U.S. Holder holds ordinary shares, we will continue to be treated as a PFIC with respect to that U.S. Holder for all succeeding years during which the U.S. Holder holds ordinary shares, even if we cease to meet the threshold requirements for PFIC status, unless the U.S. Holder elects to recognize gain, if any, as if it sold its ordinary shares as of the last day of the last tax year in which we are a PFIC (a “Purging Election”). In addition, we may, directly or indirectly, have held or hold equity interests in other PFICs (collectively, “Lower-tier PFICs”). Under attribution rules, if we are a PFIC, U.S. Holders will be deemed to own their proportionate shares of the stock of Lower-tier PFICs and will be subject to U.S. federal income tax according to the rules described in the following paragraphs on (i) certain distributions by a Lower-tier PFIC and (ii) a disposition of shares of a Lower-tier PFIC, in each case as if the U.S. Holder held those shares directly, even though it will not have received the proceeds of those distributions or dispositions directly. U.S. Holders should consult their tax advisors about the consequences to them if we own one or more Lower-tier PFICs.

S-14

If we are a PFIC for any taxable year during which a U.S. Holder holds ordinary shares (assuming the U.S. Holder has not made one of certain elections, as described below), gain recognized by the U.S. Holder on the sale or other disposition (including certain pledges) of ordinary shares (including any gain recognized as a consequence of a Purging Election) will be allocated ratably over the U.S. Holder’s holding period for the ordinary shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC will be taxed as ordinary income. The amount allocated to each other taxable year will be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge will be imposed on the resulting tax liability. Further, to the extent that any distribution received by a U.S. Holder on its ordinary shares exceeds 125% of the average of the annual distributions on the ordinary shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, that distribution will be subject to taxation in the same manner as gain.

If we were a PFIC and a U.S. Holder made either (a) an election to treat our ordinary shares as stock of a “qualified electing fund,” or “QEF”, or (b) a “mark-to-market” election with respect to our ordinary shares, that election would alleviate some of the adverse tax consequences of PFIC status and would result in an alternative treatment of the ordinary shares. If we determine that we are a PFIC for any taxable year, we intend to provide the information for U.S. Holders to make or maintain a QEF election, including information necessary to determine the appropriate income inclusion amounts for purposes of the QEF election. However, we cannot give any assurance that we will have timely knowledge of our status as a PFIC in the future or that we will provide the information necessary for U.S. Holders to make “QEF elections.” Furthermore, the availability of a “mark-to-market election” with respect to the ordinary shares is a factual determination that will depend on the manner and quantity of trading of our ordinary shares. A mark-to-market election cannot be made with respect to the stock of any of our subsidiaries. U.S. Holders should consult their tax advisors regarding whether any of these elections for alternative treatment would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances.

If we are a PFIC (or, with respect to a particular U.S. Holder, are treated as a PFIC) for a taxable year in which we pay a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders will not apply.

If we are a PFIC for a taxable year during which a U.S. Holder holds ordinary shares, the U.S. Holder will generally be required to file an annual report on IRS Form 8621 with its annual U.S. federal income tax returns, subject to certain exceptions. The failure to file IRS Form 8621 could result in the imposition of penalties and the extension of the statute of limitations with respect to U.S. federal income tax.

Prospective U.S. Holders should consult their tax advisors regarding the potential PFIC rules to an investment in ordinary shares.

Information Reporting and Backup Withholding

Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS.

Material Dutch Tax Considerations

Scope of Discussion

The section only outlines certain material Dutch tax consequences of the acquisition, holding and disposal of the ordinary shares. This section does not purport to describe all possible tax considerations or consequences that may be relevant to a holder or prospective holder of ordinary shares and does not purport to deal with the tax consequences applicable to all categories of investors, some of which (such as trusts or similar arrangements) may be subject to special rules. In view of its general nature, this section should be treated with corresponding caution.

S-15

For the purposes of this discussion, it is assumed that we are a tax resident of Germany under German national tax laws since we intended to have, from our incorporation and on a continuous basis, our place of effective management in Germany.

Except as otherwise indicated, this section is based on and only addresses the tax laws of the Netherlands, published regulations thereunder and published authoritative case law, all as in effect on the date hereof, including, for the avoidance of doubt, the tax rates, tax brackets and deemed returns applicable on the date hereof, and all of which are subject to change, possibly with retroactive effect. Where this section refers to “the Netherlands” or “Dutch” it refers only to the part of the Kingdom of the Netherlands located in Europe. The applicable tax laws or interpretations thereof may change, or the relevant facts and circumstances may change, and such changes may affect the contents of this section, which will not be updated to reflect any such changes.

This section is intended as general information only and is not Dutch tax advice or a complete description of all Dutch tax consequences relating to the acquisition, holding and disposal of the ordinary shares. Holders or prospective holders of ordinary shares should consult their own tax advisor regarding the Dutch tax consequences relating to the acquisition, holding and disposal of ordinary shares in light of their particular circumstances.

Withholding Tax on Dividends

Regular Dutch Dividend Withholding Tax

We are incorporated under the laws of the Netherlands, and therefore a Dutch tax resident for Dutch domestic tax law purposes, including the Dutch Dividend Withholding Tax Act 1969. As such, we are required to withhold Dutch dividend withholding tax at a rate of 15% from dividends distributed by us (which withholding tax will not be borne by us but will be withheld by us from the gross dividends paid on the shares). We are however also treated as a German tax resident for German domestic tax law purposes, since our place of effective management is located in Germany. Based on the so-called tie-breaker provision (the “Tie-Breaker Provision”) included in Section 4(3) of the 2012 Convention between the Federal Republic of Germany and the Kingdom of the Netherlands for the avoidance of double taxation with respect to taxes on income (the “double tax treaty between Germany and the Netherlands”) as in effect on the date hereof, our tax residence in either the Netherlands or Germany for the purposes of the double tax treaty between Germany and the Netherlands should be determined based on our place of effective management. As long as we have our place of effective management continuously in Germany, and the Tie-Breaker Provision is not changed (for instance, by change in the reservations and choices made by Germany with respect to the application of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting), we will be considered to be exclusively tax resident in Germany for purposes of the double tax treaty between Germany and the Netherlands. As a consequence, the Netherlands will be restricted to impose Dutch dividend withholding tax on dividends distributed by us pursuant to Section 10(5) of the double tax treaty between Germany and the Netherlands (and we will not be required to withhold Dutch dividend withholding tax). This restriction does not apply to dividends distributed by us to a holder of our ordinary shares who is resident or deemed to be resident in the Netherlands for Dutch personal income tax purposes or Dutch corporate income tax purposes (“Dutch Resident Individual” and “Dutch Resident Entity”, respectively) or to a holder of our ordinary shares that is neither resident nor deemed to be resident of the Netherlands (“Non-Resident Holder”) if the ordinary shares are attributable to a Dutch permanent establishment of such Non-Resident Holder, in which evens the following applies.

Dividends distributed by us are generally subject to Dutch dividend withholding tax at a rate of 15%. Generally, we are responsible for the withholding of such dividend withholding tax at source; the Dutch dividend withholding tax is for the account of the holder of ordinary shares.

The expression “dividends distributed” includes, but is not limited to:

Dutch Resident Entities generally are entitled to an exemption from, or a credit for, any Dutch dividend withholding tax against their Dutch corporate income tax liability. The credit in any given year is, however, limited to the amount of Dutch corporate income tax payable in respect of the relevant year with an indefinite carry forward of any excess amount. Dutch Resident Individuals generally are entitled to a credit for any Dutch dividend withholding tax against their Dutch personal income tax liability and to a refund of any residual Dutch dividend withholding tax. The above generally also applies to Non-Resident Holders if the ordinary shares are attributable to a Dutch permanent establishment of such Non-Resident Holder.

S-17

A Non-Resident Holder may, depending on such holder’s specific circumstances, be entitled to exemptions from, reduction of, or full or partial refund of, Dutch dividend withholding tax under Dutch domestic law, EU law, or treaties for the avoidance of double taxation in effect between the Netherlands and such other country.

Dividend Stripping

According to Dutch domestic anti-dividend stripping rules, no credit against Dutch tax, exemption from, reduction, or refund of Dutch dividend withholding tax will be granted if the recipient of the dividends we paid is not considered the beneficial owner (uiteindelijk gerechtigde; as described in the Dutch Dividend Withholding Tax Act 1965) of those dividends. This legislation generally targets situations in which a shareholder retains its economic interest in shares but reduces the withholding tax costs on dividends by a transaction with another party. It is not required for these rules to apply that the recipient of the dividends is aware that a dividend stripping transaction took place. The Dutch State Secretary of Finance takes the position that the definition of beneficial ownership introduced by this legislation will also be applied in the context of a double taxation convention.

As from January 1, 2024, more stringent rules apply to the setoff, exemption from, and reduction or refund of Dutch dividend withholding tax to address situations where a claim for setoff, exemption, reduction or refund may align with the letter of Dutch tax law or a double taxation convention but goes against the underlying intention or spirit of the dividend stripping rules, as perceived by the legislator. The burden of proof with respect to beneficial ownership of dividends distributed by us rests on the Dutch tax authorities. If, however, a shareholder would receive dividends, including dividends on the ordinary shares, in a calendar year in respect of which an aggregate amount of EUR 1,000 in Dutch dividend withholding tax would otherwise be due based on the rate of 15%, the burden of proof with respect to beneficial ownership of such dividends lies with the shareholder. Furthermore, for shares traded on a regulated market, including the ordinary shares, it has been codified that the record date is used when determining the person who is entitled to the dividend.

Conditional Withholding Tax on Dividends

In addition to the regular Dutch dividend withholding tax as described above, a Dutch conditional withholding tax will be imposed on dividends distributed by us to entities related (gelieerd) to us (within the meaning of the Dutch Withholding Tax Act 2021; Wet bronbelasting 2021), if such related entity:

all within the meaning of the Dutch Withholding Tax Act 2021.

The Dutch conditional withholding tax on dividends will be imposed at the highest Dutch corporate income tax rate in effect at the time of the distribution (2024: 25.8%). The Dutch conditional withholding tax on dividends will be reduced, but not below zero, by any regular Dutch dividend withholding tax withheld in respect of the same dividend distribution. As such, based on the currently applicable rates, the overall effective tax rate of withholding the regular Dutch dividend withholding tax (as described above) and the Dutch conditional withholding tax on dividends will not exceed the highest corporate income tax rate in effect at the time of the distribution (2024: 25.8%).

S-18

Taxes on Income and Capital Gains

Dutch Resident Entities

Generally, if the holder of ordinary shares is a Dutch Resident Entity, any income derived or deemed to be derived from the ordinary shares or any capital gains realized on the disposal or deemed disposal of the ordinary shares is subject to Dutch corporate income tax at a rate of 19% with respect to taxable profits up to €200,000 and 25.8% with respect to taxable profits in excess of that amount (rates and brackets for 2024).

Dutch Resident Individuals

If the holder of ordinary shares is a Dutch Resident Individual, any income derived or deemed to be derived from the ordinary shares or any capital gains realized on the disposal or deemed disposal of the ordinary shares is subject to Dutch personal income tax at the progressive rates (with a maximum of 49.5% in 2024), if:

Taxation of Savings and Investments

If the above-mentioned conditions (i) and (ii) do not apply to the Dutch Resident Individual, the ordinary shares will be subject to an annual Dutch income tax under the regime for savings and investments (inkomen uit sparen en beleggen). Taxation only occurs insofar the Dutch Resident Individual’s net investment assets for the year exceed a statutory threshold (heffingvrij vermogen). The net investment assets for the year are the fair market value of the investment assets less the fair market value of the liabilities on January 1 of the relevant calendar year (reference date; peildatum). Actual income or capital gains realized in respect of the ordinary shares are as such not subject to Dutch income tax.

The Dutch Resident Individual’s assets and liabilities taxed under this regime, including the ordinary shares, are allocated over the following three categories: (a) bank savings (banktegoeden), (b) other investments (overige bezittingen), including the ordinary shares, and (c) liabilities (schulden). The taxable benefit for the year (voordeel uit sparen en beleggen) is equal to the product of (x) the total deemed return divided by the sum of bank savings, other investments and liabilities and (y) the sum of bank savings, other investments and liabilities minus the statutory threshold, and is taxed at a flat rate of 36% (rate for 2024).

The deemed return applicable to other investments, including the ordinary shares, is set at 6.04% for the calendar year 2024. Transactions in the three-month period before and after January 1 of the relevant calendar year implemented to arbitrate between the deemed return percentages applicable to bank savings, other investments and liabilities will for this purpose be ignored if the holder of ordinary shares cannot sufficiently demonstrate that such transactions are implemented for other than tax reasons.

On June 6, 2024, the Dutch Supreme Court (Hoge Raad) ruled that the current Dutch income tax regime for savings and investments in certain specific circumstances contravenes with Section 1 of the First Protocol to the European Convention on Human Rights in combination with Section 14 of the European Convention on Human Rights (the “Ruling”). This is, in short, the case in the event the deemed return on the investment assets exceeds the actual return realized in respect thereof (calculated in line with the rules set out in the Ruling and successfully demonstrated by the taxpayer). Holders of ordinary shares are advised to consult their own tax advisor to ensure that the tax in respect of the ordinary shares is levied in accordance with the applicable Dutch tax rules at the relevant time.

S-19

Non-Residents of the Netherlands

A holder of ordinary shares that is neither a Dutch Resident Entity nor a Dutch Resident Individual will not be subject to Dutch income tax in respect of income derived or deemed to be derived from the ordinary shares or in respect of capital gains realized on the disposal or deemed disposal of the ordinary shares provided that:

Gift and Inheritance Taxes

Residents of the Netherlands

Gift or inheritance taxes will arise in the Netherlands with respect to a transfer of ordinary shares by way of a gift by, or on the death of, a holder of such ordinary shares who is resident or deemed resident of the Netherlands at the time of the gift or such holder’s death.

Non-Residents of the Netherlands

No gift or inheritance taxes will arise in the Netherlands with respect to a transfer of ordinary shares by way of a gift by, or on the death of, a holder of such ordinary shares who is neither resident nor deemed to be resident of the Netherlands, unless:

For purposes of Dutch gift and inheritance taxes, amongst others, a person that holds the Dutch nationality will be deemed to be resident of the Netherlands if such person has been a resident of the Netherlands at any time during the ten years preceding the date of the gift or such person’s death. Additionally, for purposes of Dutch gift tax, amongst others, a person not holding the Dutch nationality will be deemed to be resident of the Netherlands if such person has been a resident of the Netherlands at any time during the twelve months preceding the date of the gift. Applicable tax treaties may override deemed residency.

Value Added Tax (VAT)

No Dutch VAT will be payable by a holder of ordinary shares in respect of any payment in consideration for the holding or disposal of the ordinary shares.

Real Property Transfer Tax

Under circumstances, the ordinary shares could, for the purposes of Dutch real property transfer tax (overdrachtsbelasting), be treated as real property (fictieve onroerende zaken) located in the Netherlands, in which case this tax could be payable upon acquisition of the ordinary shares.

The ordinary shares will generally not be treated as real property (fictieve onroerende zaken) if at the time of, or at any time during the year preceding, the acquisition of the ordinary shares:

S-20

Real property as referred to under (i) and (ii) above includes legal ownership and more limited legal rights over the property (rights in rem) (zakelijke rechten) as well as contractual rights that give us economic exposure to the value of such real property, and certain participations or interests in entities that are treated as real property (fictieve onroerende zaken).

Our assets do not include and have not included real property situated in the Netherlands as described above. Consequently, no Dutch real property transfer tax becomes payable upon an acquisition of the ordinary shares.

Stamp Duties

No Dutch documentation taxes (commonly referred to as stamp duties) will be payable by a holder of ordinary shares in respect of any payment in consideration for the holding or disposal of the ordinary shares.

Material German Tax Considerations

The following section is a description of the material German tax considerations that become relevant when acquiring, owning and transferring Immatics’ ordinary shares. It is based on the German tax law applicable as of the date of this prospectus supplement without prejudice to any amendments introduced at a later date and implemented with or without retroactive effect.

This section is intended as general information only and does not purport to be a comprehensive or complete description of all potential German tax effects of the acquisition, ownership or transfer of ordinary shares and does not set forth all German tax considerations that may be relevant to a particular person’s decision to acquire ordinary shares. It does not constitute particular German tax advice and potential purchasers of Immatics’ ordinary shares are urged to consult their own tax advisors regarding the tax consequences of the acquisition, ownership and transfer of ordinary shares in light of their particular circumstances with regard to the application of German tax law to their particular situations (including full or partial tax exemptions of certain pension or investment funds or non-profit organizations), in particular with respect to the procedure to be complied with to obtain a relief of withholding tax on dividends and on capital gains (Kapitalertragsteuer) and with respect to the influence of double tax treaty provisions, as well as any tax consequences arising under the laws of any state, local or other non-German jurisdiction. For German tax purposes, a shareholder may include an individual who or an entity that does not have the legal title to the ordinary shares, but to whom nevertheless the ordinary shares are attributed, based either on such individual or entity owning a beneficial interest in the ordinary shares or based on specific statutory provisions.

All of the following is subject to change. Such changes could apply retroactively and could affect the consequences set forth below. This section does not refer to any foreign account tax compliance act (FATCA) aspects.

Immatics’ Tax Residency Status

Immatics has its statutory seat in the Netherlands and its sole place of management in Germany and is therefore tax resident in Germany (for purposes of the German-Dutch tax treaty). Thus, Immatics qualifies as a corporation subject to German unlimited liability for corporate income tax purposes. However, because Immatics’ tax residency depends on future facts regarding its place of management, the German unlimited liability for corporate income tax purposes may change in the future.

Taxation of Dividends

Withholding Tax on Dividend Payments

Dividends distributed from Immatics to its shareholders are generally subject to German withholding tax, conditionally upon certain exemptions (for example, repayments of capital from the tax contribution account (steuerliches Einlagekonto)), as further described herein. The withholding tax rate is 25% plus a 5.5% solidarity surcharge (Solidaritätszuschlag) thereon totaling 26.375% of the gross dividend amount. Withholding tax is to be withheld and passed on for the account of the shareholders by a domestic branch of a domestic or foreign credit or financial services institution (Kredit- und Finanzdienstleistungsinstitut), by the domestic securities trading company (inländisches Wertpapierhandelsunternehmen) or a domestic securities trading bank (inländische Wertpapierhandelsbank) which keeps and administers the ordinary shares and disburses or credits the dividends or disburses the dividends to a foreign agent, or by the securities custodian bank (Wertpapiersammelbank) to which the ordinary shares were entrusted for collective custody if the dividends are distributed to a foreign agent by such securities custodian bank (which is referred to as the “Dividend Paying Agent”). In case the ordinary shares are not held in collective deposit with a Dividend Paying Agent, Immatics is responsible for withholding and remitting the

S-21

tax to the competent tax office. Such withholding tax is levied and withheld irrespective of whether and to what extent the dividend distribution is taxable at the level of the shareholder and whether the shareholder is a person residing in Germany or in a foreign country.

In the case of dividends distributed to a company within the meaning of Art. 2 of the amended EU Directive 2011/96/EU of the Council of November 30, 2011 (the “EU Parent Subsidiary Directive”) domiciled in another Member State of the European Union, withholding tax is effectively reduced to zero. This also applies to dividends distributed to a permanent establishment located in another Member State of the European Union of such a parent company or of a parent company tax resident in Germany if the participation in Immatics is effectively connected with this permanent establishment. The key prerequisite for the application of the EU Parent Subsidiary Directive is that the shareholder has held a direct participation in the share capital of Immatics of at least 10% for an uninterrupted period of at least one year.

The withholding tax on dividends distributed to other foreign resident shareholders is reduced in accordance with an applicable double tax treaty (to 15%, 5% or 0%, depending on certain prerequisites) if Germany has concluded such double tax treaty with the country of residence of the shareholder and if the shareholder does not hold his or her ordinary shares either as part of the assets of a permanent establishment or a fixed place of business in Germany or as business assets for which a permanent representative has been appointed in Germany. Further, the foreign resident shareholder must be eligible for treaty purposes and no limitation of benefits provision in a double tax treaty and—both in relation to a reduction pursuant to the EU Parent Subsidiary Directive and an applicable tax treaty—no German anti-directive/treaty shopping provision of Section 50d paragraph 3 of the German Income Tax Act (Einkommensteuergesetz) must be applicable.

However, the deduction of withholding taxes will generally apply irrespective of a possible reduction pursuant to the EU Parent Subsidiary Directive or an applicable double tax treaty except for the case that the recipient of the dividends has been granted an exemption from the German Federal Central Tax Office (Bundeszentralamt für Steuern) upon formal application by the recipient of the dividends (Freistellung im Steuerabzugsverfahren). In case of deducted withholding taxes, the reduction of the withholding tax pursuant to both the EU Parent Subsidiary Directive and an applicable double tax treaty is procedurally granted in such a manner that the difference between the total amount withheld, including the solidarity surcharge, and the tax liability determined on the basis of the EU Parent Subsidiary Directive (0%) or on the basis of the tax rate set forth in the applicable double tax treaty (15% unless further qualifications are met) is upon request refunded by the German Federal Central Tax Office (Bundeszentralamt für Steuern).

In the case of dividends received by corporations who are not tax resident in Germany, two-fifths of the withholding tax deducted and remitted are refunded without the need to fulfill all prerequisites required for such refund under the EU Parent Subsidiary Directive or under a double tax treaty or if no double tax treaty has been concluded between the state of residence of the shareholder, however, likewise subject to the conditions of the German anti-directive/treaty shopping provision.

In order to receive a refund pursuant to a double tax treaty or the aforementioned option for foreign corporations, the shareholder has to submit a completed form for refund (available at the website of the Federal Central Tax Office (http://www.bzst.de) as well as at the German embassies and consulates) together with a withholding tax certificate (Kapitalertragsteuerbescheinigung) issued by the institution that deducted the respective withholding tax.

The aforementioned reductions of (or exemptions from) withholding tax are further restricted if (i) the applicable double tax treaty provides for a tax reduction resulting in an applicable tax rate of less than 15% and (ii) the shareholder is not a corporation that directly holds at least 10% in the equity capital of Immatics and is subject to tax on its income and profits in its state of residence without being exempt. In this case, the reduction of (or exemption from) withholding tax is subject to the following three cumulative prerequisites: (i) the shareholder must qualify as beneficial owner of the shares in a company for a minimum holding period of 45 consecutive days occurring within a period of 45 days prior and 45 days after the due date of the dividends, (ii) the shareholder has to bear at least 70% of the change in value risk related to the shares in a company during the minimum holding period without being directly or indirectly hedged, and (iii) the shareholder must not be required to fully or largely compensate directly or indirectly the dividends to third parties.

S-22

In the absence of the fulfillment of all of the three prerequisites, three-fifths of the withholding tax imposed on the dividends must not be credited against the shareholder’s (corporate) income tax liability, but may, upon application, be deducted from the shareholder’s tax base for the relevant assessment period. Furthermore, a shareholder that has received gross dividends without any deduction of withholding tax due to a tax exemption without qualifying for such a full tax credit has (i) to notify the competent local tax office accordingly, (ii) to declare according to the officially prescribed form and (iii) has to make a payment in the amount of the omitted withholding tax deduction.

However, these special rules on the restriction of withholding tax credit do not apply to a shareholder whose overall dividend earnings within an assessment period do not exceed €20,000 or that has been the beneficial owner of the shares in a company for at least one uninterrupted year upon receipt of the dividends.

For individual or corporate shareholders tax resident outside Germany not holding the ordinary shares through a permanent establishment (Betriebsstätte) in Germany or as business assets (Betriebsvermögen) for which a permanent representative (ständiger Vertreter) has been appointed in Germany, the remaining and paid withholding tax (if any) is then final (i.e., not refundable) and settles the shareholder’s limited tax liability in Germany. For individual or corporate shareholders tax resident in Germany (for example, those shareholders whose residence, domicile, registered office or place of management is located in Germany) holding their ordinary shares as business assets, as well as for shareholders tax resident outside of Germany holding their ordinary shares through a permanent establishment in Germany or as business assets for which a permanent representative has been appointed in Germany, the withholding tax withheld (including solidarity surcharge) can be credited against the shareholder’s personal income tax or corporate income tax liability in Germany. Any withholding tax (including solidarity surcharge) in excess of such tax liability is refunded. For individual shareholders tax resident in Germany holding Immatics’ ordinary shares as private assets, the withholding tax is a final tax (Abgeltungsteuer), subject to the exceptions described in the following section.

Taxation of Dividend Income of Shareholders Tax Resident in Germany Holding Immatics’ Ordinary Shares as Private Assets (Private Individuals)

For individual shareholders (individuals) resident in Germany holding Immatics’ ordinary shares as private assets, dividends are subject to a flat rate tax which is satisfied by the withholding tax actually withheld (Abgeltungsteuer). Accordingly, dividend income will be taxed at a flat tax rate of 25% plus a 5.5% solidarity surcharge thereon totaling 26.375% and church tax (Kirchensteuer) in case the shareholder is subject to church tax because of his or her personal circumstances. An automatic procedure for deduction of church tax by way of withholding will apply to shareholders being subject to church tax unless the shareholder has filed a blocking notice (Sperrvermerk) with the German Federal Tax Office (details related to the computation of the specific tax rate including church tax are to be discussed with the individual tax advisor of the relevant shareholder). Except for an annual lump sum savings allowance (Sparer-Pauschbetrag) of up to €1,000 (for individual filers) or up to €2,000 (for married couples and for partners in accordance with the registered partnership law (Gesetz über die Eingetragene Lebenspartnerschaft) filing jointly), private individual shareholders will not be entitled to deduct expenses incurred in connection with the capital investment from their dividend income.

The income tax owed for the dividend income is satisfied by the withholding tax withheld by the Dividend Paying Agent. However, if the flat tax results in a higher tax burden as opposed to the private individual shareholder’s personal income tax rate, the private individual shareholder can opt for taxation at his or her personal income tax rate. In that case, the final withholding tax will be credited against the income tax. The option can be exercised only for all capital income from capital investments received in the relevant assessment period uniformly and married couples as well as partners in accordance with the registered partnership law filing jointly may only jointly exercise the option.

Exceptions from the flat rate tax (satisfied by withholding the tax at source, Abgeltungswirkung) may apply—that is, only upon application—for shareholders who have a shareholding of at least 25% in Immatics and for shareholders who have a shareholding of at least 1% in Immatics and work for a company in a professional capacity. In such a case, the same rules apply as for sole proprietors holding the ordinary shares as business assets (see below “Taxation of Dividend Income of Shareholders Tax Resident in Germany Holding the Company’s Ordinary Shares as Business Assets—Sole Proprietors”). Further, the flat rate tax does not apply if and to the extent dividends reduced Immatics taxable income.

S-23

Taxation of Dividend Income of Shareholders Tax Resident in Germany Holding Immatics’ Ordinary Shares as Business Assets

If a shareholder holds Immatics’ ordinary shares as business assets, the taxation of the dividend income depends on whether the respective shareholder is a corporation, a sole proprietor or a partnership.

Corporations

Dividend income of corporate shareholders is exempt from corporate income tax, provided that the corporation holds a direct participation of at least 10% in the share capital of a company at the beginning of the calendar year in which the dividends are paid (participation exemption). The acquisition of a participation of at least 10% in the course of a calendar year is deemed to have occurred at the beginning of such calendar year. Participations in the share capital of the company which a corporate shareholder holds through a partnership, including co-entrepreneurships (Mitunternehmerschaften), are attributable to such corporate shareholder only on a pro rata basis at the ratio of the interest share of the corporate shareholder in the assets of the relevant partnership. However, 5% of the tax-exempt dividends are deemed to be non-deductible business expenses for tax purposes and therefore are effectively subject to corporate income tax (plus solidarity surcharge) and trade tax; i.e., tax exemption of 95%. Business expenses incurred in connection with the dividends received are entirely tax deductible. The participation exemption does not apply if and to the extent dividends reduced Immatics taxable income.

For trade tax purposes the entire dividend income is subject to trade tax (i.e., the tax-exempt dividends must be added back when determining the trade taxable income), unless the corporation shareholder holds at least 15% of the company’s registered share capital at the beginning of the relevant tax assessment period (Erhebungszeitraum). In case of an indirect participation via a partnership please refer to the section “Partnerships” below.

If the shareholding is below 10% in the share capital, dividends are taxable at the applicable corporate income tax rate of 15%, plus a 5.5% solidarity surcharge thereon and trade tax (the rate of which depends on the applicably municipality levy rate determined by the municipality the corporate shareholder has its place of management and permanent establishments respectively).

Special regulations apply which abolish the 95% tax exemption, if the company’s ordinary shares are held as trading portfolio assets in the meaning of Section 340e of the German Commercial Code (Handelsgesetzbuch) by (i) a credit institution (Kreditinstitut), (ii) a financial service institution (Finanzdienstleistungsinstitut) or (iii) a financial enterprise within the meaning of the German Banking Act (Kreditwesengesetz), in case more than 50% of the shares of such financial enterprise are held directly or indirectly by a credit institution or a financial service institution, as well as by a life insurance company, a health insurance company or a pension fund in case the shares are attributable to the capital investments, resulting in fully taxable income.

Sole Proprietors

For sole proprietors (individuals) resident in Germany holding ordinary shares as business assets dividends are subject to the partial income rule (Teileinkünfteverfahren). Accordingly, only (i) 60% of the dividend income will be taxed at his/her personal income tax rate plus 5.5% solidarity surcharge thereon and church tax (if applicable) and (ii) 60% of the business expenses related to the dividend income are deductible for tax purposes. In addition, the dividend income is entirely subject to trade tax if the ordinary shares are held as business assets of a permanent establishment in Germany within the meaning of the German Trade Tax Act (Gewerbesteuergesetz), unless the shareholder holds at least 15% of the company’s registered share capital at the beginning of the relevant assessment period. The trade tax levied will be eligible for credit against the shareholder’s personal income tax liability based on the applicable municipal trade tax rate and the individual tax situation of the shareholder limited to currently 4.0 times the trade tax measurement amount (Gewerbesteuer-Messbetrag).

Partnerships

In case ordinary shares are held by a partnership, the partnership itself is not subject to corporate income tax or personal income tax. In this regard, corporate income tax or personal income tax (and church tax, if applicable) as well as solidarity surcharge are levied only at the level of the partner with respect to their relevant part of the partnership’s taxable income and depending on their individual circumstances:

S-24

In case the partnership is a (operative or deemed) commercial partnership with its place of management in Germany the dividend income is subject to German trade tax at the level of the partnership, unless the partnership holds at least 15% of a company’s registered share capital at the beginning of the relevant assessment period, in which case the dividend income is exempt from trade tax.

Investment Funds

Investment funds (Investmentfonds) and specialized investment funds (Spezial-Investmentfonds) in the meaning of the German Investment Tax Act (Investmentsteuergesetz) and their investors are subject to special rules concerning the taxation of dividends, in particular in relation to the application of the German participation exemption, withholding tax treatment (applicable rate and exemption/refund procedure) and tax assessment.

Taxation of Dividend Income of Shareholders Tax Resident Outside of Germany

For foreign individual or corporate shareholders tax resident outside of Germany not holding the ordinary shares through a permanent establishment in Germany or as business assets for which a permanent representative has been appointed in Germany, the deducted withholding tax (possibly reduced by way of a tax relief under a double tax treaty or domestic tax law, such as in connection with the EU Parent Subsidiary Directive) is final (that is, not refundable) and settles the shareholder’s limited tax liability in Germany, unless the shareholder is entitled to apply for a withholding tax refund or exemption.

In contrast, individual or corporate shareholders tax resident outside of Germany holding the company’s ordinary shares through a permanent establishment in Germany or as business assets for which a permanent representative has been appointed in Germany are subject to the same rules as applicable (and described above) to shareholders resident in Germany holding the ordinary shares as business assets. The withholding tax withheld (including solidarity surcharge) is credited against the shareholder’s personal income tax or corporate income tax liability in Germany.

Taxation of Capital Gains

Withholding Tax on Capital Gains

Capital gains realized on the disposal of ordinary shares are only subject to withholding tax if (i) a permanent establishment in Germany of a German or foreign credit or financial institution, (ii) a German securities trading company or (iii) a German securities trading bank stores or administrates or carries out the disposal of the ordinary shares and pays or credits the capital gains. In those cases, the institution (and not the company) is required to deduct the withholding tax at the time of payment for the account of the shareholder and has to pay the withholding tax to the competent tax authority.

In case the ordinary shares in the company are held (i) as business assets by a sole proprietor, a partnership or a corporation and such shares are attributable to a German business or (ii) in case of a corporation being subject to unlimited corporate income tax liability in Germany, the capital gains are not subject to withholding tax. In case of the aforementioned exemption under (i) above, the withholding tax exemption is subject to the condition that the paying agent has been notified by the beneficiary (Gläubiger) that the capital gains are exempt from withholding tax. The respective notification has to be filed by using the officially prescribed form.

Taxation of Capital Gains Realized by Shareholders Tax Resident in Germany Holding Immatics’ Ordinary Shares as Private Assets (Private Individuals)

For individual shareholders (individuals) resident in Germany holding ordinary shares as private assets, capital gains realized on the disposal of ordinary shares are subject to final withholding tax (Abgeltungsteuer). Accordingly, capital gains will be taxed at a flat tax rate of 25%, plus a 5.5% solidarity surcharge thereon totaling 26.375% and church tax, in case the shareholder is subject to church tax because of his or her personal circumstances. An automatic procedure for deduction of church tax by way of withholding will apply to shareholders being subject to church tax unless the shareholder has filed a blocking notice (Sperrvermerk) with the German Federal Central Tax Office (details related to the computation of the specific tax rate including church tax are to be discussed with the personal tax

S-25

advisor of the relevant shareholder). The taxable capital gain is calculated by deducting the acquisition costs of the ordinary shares and the expenses directly and materially related to the disposal from the proceeds of the disposal. Apart from that, except for an annual lump sum savings allowance (Sparer-Pauschbetrag) of up to €1,000 (for individual filers) or up to €2,000 (for married couples and for partners in accordance with the registered partnership law (Gesetz über die Eingetragene Lebenspartnerschaft) filing jointly), private individual shareholders will not be entitled to deduct expenses incurred in connection with the capital investment from their capital gain.

In case the flat tax results in a higher tax burden as opposed to the private individual shareholder’s personal income tax rate, the private individual shareholder can opt for taxation at his or her personal income tax rate. In that case, the withholding tax (including solidarity surcharge) withheld will be credited against the income tax. The option can be exercised only for all capital income from capital investments received in the relevant assessment period uniformly and married couples as well as for partners in accordance with the registered partnership law filing jointly may only jointly exercise the option.

Capital losses arising from the disposal of the ordinary shares can only be offset against other capital gains resulting from the disposition of the ordinary shares or shares in other stock corporations during the same calendar year. Offsetting of overall losses with other income (such as business or rental income) and other capital income is not possible. Such losses are to be carried forward and to be offset against positive capital gains deriving from the disposal of ordinary shares in stock corporations in future years.

The final withholding tax (Abgeltungsteuer) will not apply if the seller of the ordinary shares or in case of gratuitous transfer, its legal predecessor has held, directly or indirectly, at least 1% of the company’s registered share capital at any time during the five years prior to the disposal. In that case capital gains are subject to the partial income rule (Teileinkünfteverfahren). Accordingly, only (i) 60% of the capital gains will be taxed at his/her personal income tax rate, plus a 5.5% solidarity surcharge thereon and church tax (if applicable) and (ii) 60% of the business expenses related to the capital gains are deductible for tax purposes. The withholding tax withheld (including solidarity surcharge) will be credited against the shareholder’s personal income tax liability in Germany.

Taxation of Capital Gains Realized by Shareholders Tax Resident in Germany Holding Immatics’ Ordinary Shares as Business Assets

If a shareholder holds ordinary shares as business assets, the taxation of capital gains realized on the disposal of such shares depends on whether the respective shareholder is a corporation, a sole proprietor or a partnership:

Corporations

Capital gains realized on the disposal of ordinary shares by a corporate shareholder are generally exempt from corporate income tax and trade tax. However, 5% of the tax-exempt capital gains are deemed to be non-deductible business expenses for tax purposes and therefore are effectively subject to corporate income tax (plus solidarity surcharge) and trade tax; i.e., tax exemption of 95%. Business expenses incurred in connection with the capital gains are entirely tax deductible.

Capital losses incurred upon the disposal of ordinary shares or other impairments of the share value are not tax deductible. A reduction of profit is also defined as any losses incurred in connection with a loan or security in the event the loan or the security is granted by a shareholder or by a related party thereto or by a third person with the right of recourse against the before mentioned persons and the shareholder holds directly or indirectly more than 25% of the company’s registered share capital.

Special regulations apply, if the ordinary shares are held as trading portfolio assets by a credit institution, a financial service institution or a financial enterprise within the meaning of the German Banking Act (Kreditwesengesetz) as well as by a life insurance company, a health insurance company or a pension fund (see “—Material German Tax Considerations—Taxation of Dividends—Corporations”).

Sole Proprietors

If the ordinary shares are held by a sole proprietor, capital gains realized on the disposal of the ordinary shares are subject to the partial income rule (Teileinkünfteverfahren). Accordingly, only (i) 60% of the capital gains will be taxed at his/her personal income tax rate plus 5.5% solidarity surcharge thereon and church tax (if applicable) and (ii) 60% of the business expenses related to the dividend income are deductible for tax purposes. In addition, 60% of the capital gains are subject to trade tax if the ordinary shares are held as business assets of a permanent

S-26

establishment in Germany within the meaning of the German Trade Tax Act (Gewerbesteuergesetz). The trade tax levied, depending on the applicable municipal trade tax rate and the individual tax situation, is partly or entirely be credited against the shareholder’s personal income tax liability.

Partnerships

In case the ordinary shares are held by a partnership, the partnership itself is not subject to corporate income tax or personal income tax as well as solidarity surcharge (and church tax) since partnerships qualify as transparent for German income tax purposes. In this regard, corporate income tax or personal income tax as well as solidarity surcharge (and church tax, if applicable) are levied only at the level of the partner with respect to their relevant part of the partnership’s taxable income and depending on their individual circumstances:

In addition, if the partnership is liable to German trade tax, 60% of the capital gains are subject to trade tax at the level of the partnership, to the extent the partners are individuals, and 5% of the capital gains are subject to trade tax, to the extent the partners are corporations. However, if a partner is a private individual, the trade tax paid at the level of the partnership is credited against the partner’s personal income tax liability at up to 4.0 times of the trade tax measurement amount (Gewerbesteuer-Messbetrag) depending on the applicable municipal trade tax levy rate and the personal tax situation.

Taxation of Capital Gains Realized by Shareholders Tax Resident Outside of Germany

Capital gains realized on the disposal of the ordinary shares by a shareholder tax resident outside of Germany are subject to German taxation provided that (i) the company’s ordinary shares are held as business assets of a permanent establishment or as business assets for which a permanent representative has been appointed in Germany, or (ii) the shareholder or, in case of a gratuitous transfer, its legal predecessor has held, directly or indirectly at least 1% of the company’s shares capital at any time during a five-year period prior to the disposal. In these cases, capital gains are generally subject to the same rules as described above for shareholders resident in Germany. However, except for the cases referred to in (i) above, most double tax treaties concluded by Germany provide for a full exemption from German taxation except that the company is considered a real estate holding entity for treaty purposes. Further, the participation exemption applies in full resulting in a tax exemption of 100% (i.e., no deemed non-tax-deductible business expenses).

Inheritance and Gift Tax

The transfer of Immatics’ ordinary shares to another person by way of succession or donation is subject to German inheritance and gift tax (Erbschaft- und Schenkungsteuer) if:

Special regulations apply to qualified German citizens who maintain neither a residence nor their domicile in Germany but in a low tax jurisdiction and to former German citizens, also resulting in inheritance and gift tax. The

S-27

few double tax treaties on inheritance and gift tax which Germany has entered into provide that German inheritance and gift tax is levied only in case of (i) and, with certain restrictions, in case of (ii).

Value Added Tax (VAT)

No German value added tax (Umsatzsteuer) will be payable by a shareholder in respect of any purchase, ownership and disposal of the ordinary shares except for a valid option to waive VAT exemption requiring a sale between entrepreneurs for VAT purposes.

Transfer Taxes

No German capital transfer tax (Kapitalverkehrsteuer) or stamp duty (Stempelgebühr) or similar taxes are levied when acquiring, owning or transferring the company’s ordinary shares. Net wealth tax (Vermögensteuer) is currently not levied in Germany.

On January 22, 2013, the Council of the European Union approved the resolution of the ministers of finance from eleven EU member states (including Germany) to introduce a financial transaction tax (“FTT”) within the framework of enhanced cooperation. On February 14, 2013, the European Commission accepted the proposal for a Council Directive implementing enhanced cooperation in the area of FTT. The plan focuses on levying a financial tax of 0.1% (0.01% for derivatives) on the purchase and sale of financial instruments.

A joint statement issued by ten of the eleven participating EU Member States in October 2016 reaffirmed the intention to introduce an FTT. However, at the moment not many details are available. Thus, it is not known to what extent the elements of the European Commission’s proposal outlined in the preceding paragraph will be followed in relation to the taxation of shares. The FTT proposal remains subject to negotiation between the participating EU Member States and is subject to political discussion. It may therefore be altered prior to the implementation, the timing of which remains unclear. With the EU Council’s conclusion of COVID-19 financial support and the agreement on an FTT becomes more realistic as one of the measures to fund the EU’s response to the COVID-19 pandemic. Additional EU Member States may decide to participate. If an EU-wide FTT (see above) fails, representatives of the IfW (Institute for the World Economy) intend to advocate the introduction of a comprehensive version of the tax in Germany after the COVID-19 pandemic. Prospective holders of the ordinary shares are advised to seek their own professional advice in relation to FTT.

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement, dated as of the date of this prospectus supplement, among us and Jefferies LLC, Jefferies GmbH, BofA Securities, Inc. and Leerink Partners LLC, as the representatives of the underwriters named below and the joint book-running managers of this offering, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the respective number of ordinary shares shown opposite its name below.

The underwriting agreement provides that the obligations of the several underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers’ certificates and legal opinions and approval of certain legal matters by their counsel. The underwriting agreement provides that the underwriters will purchase all of the ordinary shares if any of them are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

We have granted the underwriters an option to purchase up to       additional ordinary shares from us. The underwriters have 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriters have advised us that, following the completion of this offering, they currently intend to make a market in the ordinary shares as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and the underwriters may discontinue any market-making activities at any time without notice in their sole discretion. Accordingly, no assurance can be given as to the liquidity of the trading market for the ordinary shares, that you will be able to sell any of the ordinary shares held by you at a particular time or that the prices that you receive when you sell will be favorable.

The underwriters are offering the ordinary shares subject to their acceptance of the ordinary shares from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. In addition, the underwriters have advised us that they do not intend to confirm sales to any account over which they exercise discretionary authority.

Commission and Expenses

The underwriters have advised us that they propose to offer the ordinary shares to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers, which may include the underwriters, at that price less a concession not in excess of $   per ordinary share. After the offering, the public offering price and concession to dealers may be reduced by the representatives. No such reduction will change the amount of proceeds to be received by us as set forth on the cover page of this prospectus.

S-29

The following table shows the per share and total underwriting discount to be paid to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate expenses payable by us in connection with this offering, other than the underwriting discounts and commissions referred to above, will be approximately $  million. We have agreed to reimburse the underwriters for up to $25,000 of expenses relating to determining this offering’s compliance with Financial Industry Regulatory Authority rules.

Listing

Our ordinary shares are listed on Nasdaq under the trading symbol “IMTX”.

Stamp Taxes

If you purchase the ordinary shares offered by this prospectus, you may be required to pay stamp taxes and other charges under the laws and practices of the country of purchase, in addition to the offering price listed on the cover page of this prospectus.

No Sales of Similar Securities

We, our officers and our directors have agreed not to directly or indirectly:

This restriction terminates after the 60th day after the date of this prospectus and does not apply to a transfer made by a director or officer (a) as a bona fide gift, (b) by will or intestacy, (c) by operation of law, (d) if an individual, to any immediate family member, any trust for the direct or indirect benefit of such individual or their immediate family or any entity of which the individual and their immediate family are the legal and beneficial owner of all of the outstanding equity securities or similar interests, (e) in connection with the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, provided that such plan does not provide for the transfer of ordinary shares or derivative instruments during the “lock-up” period described in this paragraph, (f) pursuant to any trading plan pursuant to Rule 10b5-1 under the Exchange Act that has been entered into prior to the date of this prospectus supplement, (g) in connection with the conversion, exercise or exchange of warrants to purchase ordinary shares outstanding as of the date of this prospectus supplement, (h) in connection with the exercise of options to purchase ordinary shares or other securities received pursuant to employee benefit or other compensation plans existing as of the date of this prospectus supplement, (i) if a business entity, to another business entity that is an affiliate or to any investment fund or other entity that controls or manages, or is under common control, such entity, or to such entity’s limited partners, members or shareholder, (j) pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by our board of directors and made to all holders of our capital stock involving a change of control, or (k) pursuant to the provisions of our policy with respect to the recoupment of incentive-based compensation, which exceptions are subject to certain other customary restrictions, or to our (i) issuance of the ordinary shares being offered in this offering, (ii) issuance of ordinary shares upon the

S-30

exercise of an option or warrant or the conversion of or exchange for a security outstanding on the date of this prospectus supplement, (iii) issuance to a third party or a group of third parties of ordinary shares or securities convertible into or exercisable or exchangeable for ordinary shares in connection with a merger, acquisition or other strategic or commercial relationship and the filing of a registration statement, prospectus or prospectus supplement for the registration of the resale of such ordinary shares, provided that the aggregate number of ordinary shares issued or issuable will not exceed 5% of the total number of issued and outstanding shares immediately following the closing of the offering, (iv) issuance of ordinary shares or options to purchase ordinary shares granted pursuant to existing employee benefit plans, (v) filing of any registration statement on Form S-8 in respect of any employee benefit plan in effect on the date of this prospectus supplement, (vi) facilitating the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act, provided that such plan does not provide for the transfer of ordinary shares during the “lock-up” period described in this paragraph and no public announcement or filing under the Exchange Act is required or voluntarily made in connection with such plan and (vii) filing of a registration statement, prospectus or prospectus supplement for the registration of ordinary shares issuable upon the exercise of warrants outstanding on the date of this prospectus supplement.

The representatives may, in their sole discretion and at any time or from time to time before the termination of the 60-day period, release all or any portion of the securities subject to lock-up agreements. There are no existing agreements between the underwriters and any of our directors or officers who will execute a lock-up agreement, providing consent to the sale of shares prior to the expiration of the lock-up period.

Stabilization

The underwriters have advised us that they, pursuant to Regulation M under the Exchange Act, may engage in short sale transactions, stabilizing transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering. These activities may have the effect of stabilizing or maintaining the market price of the ordinary shares at a level above that which might otherwise prevail in the open market. Short sales involve the sale by an underwriter of a greater number of shares than it is required to purchase in this offering. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ option to purchase additional shares referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the ordinary shares in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

A stabilizing bid is a bid for the purchase of ordinary shares on behalf of the underwriters for the purpose of fixing or maintaining the price of the ordinary shares. A syndicate covering transaction is the bid for or the purchase of ordinary shares on behalf of the underwriters to reduce a short position incurred by the underwriters in connection with the offering. Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our ordinary shares or preventing or retarding a decline in the market price of our ordinary shares. As a result, the price of our ordinary shares may be higher than the price that might otherwise exist in the open market. A penalty bid is an arrangement permitting the underwriters to reclaim the selling concession otherwise accruing to a syndicate member in connection with the offering if the ordinary shares originally sold by such syndicate member are purchased in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.

Neither we, nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the ordinary shares. The underwriters are not obligated to engage in these activities and, if commenced, any of the activities may be discontinued at any time.

The underwriters may also engage in passive market making transactions in our ordinary shares on the Nasdaq Capital Market in accordance with Rule 103 of Regulation M during a period before the commencement of offers or sales of our ordinary shares in this offering and extending through the completion of distribution. A passive market

S-31

maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, that bid must then be lowered when specified purchase limits are exceeded.

Electronic Distribution

A prospectus in electronic format may be made available by e-mail or on the web sites or through online services maintained by one or more of the underwriters or their affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of ordinary shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus in electronic format, the information on the underwriters’ web sites and any information contained in any other web site maintained by any of the underwriters is not part of this prospectus, has not been approved and/or endorsed by us or the underwriters and should not be relied upon by investors.

Other Activities and Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and certain of their respective affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for us and our affiliates, for which they received or will receive customary fees and expenses. For example, we are party to a sales agreement with Leerink Partners LLC, acting as sales agent, pursuant to which we may issue and sell, from time to time, our ordinary shares.

In the ordinary course of their various business activities, the underwriters and certain of their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments issued by us and our affiliates. If the underwriters or their respective affiliates have a lending relationship with us, they routinely hedge their credit exposure to us consistent with their customary risk management policies. The underwriters and their respective affiliates may hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the ordinary shares offered hereby. Any such short positions could adversely affect future trading prices of the ordinary shares offered hereby. The underwriters and certain of their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Settlement Cycle

It is expected that delivery of the ordinary shares will be made against payment therefor on or about the date of delivery specified on the cover page of this prospectus supplement, which is the second business day following the date of pricing of the ordinary shares (this settlement cycle being referred to as “T+2”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the ordinary shares prior to the business day preceding the date of delivery will be required, by virtue of the fact that the ordinary shares initially will settle in T+2, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisors.

Selling Restrictions

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed

S-32

or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to the offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”); (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”).

For the purposes of this provision, the expression an “offer to the public” in relation to securities in any Relevant State means the communication in any form and by any means of sufficient information on the terms of the offer and any securities to be offered so as to enable an investor to decide to purchase or subscribe for any securities, and the expression “Prospectus Regulation” means Regulation (EU) 2017/1129, as amended.

Notice to Prospective Investors in Australia

This prospectus:

The securities may not be directly or indirectly offered for subscription or purchased or sold, and no invitations to subscribe for or buy the securities may be issued, and no draft or definitive offering memorandum, advertisement or other offering material relating to any securities may be distributed in Australia, except where disclosure to investors is not required under Chapter 6D of the Corporations Act or is otherwise in compliance with all applicable Australian laws and regulations.

OUR COMPANY

Overview

We are a clinical-stage biotechnology company dedicated to the development of T cell receptor (“TCR”)-based immunotherapies for the treatment of patients with solid tumors with unmet medical need. Our objective is to deliver a meaningful impact on the lives of these patients by developing novel TCR-based immunotherapies that achieve an effect beyond an incremental clinical benefit.

We strive to become an industry-leading, fully integrated global biopharmaceutical company engaged in developing, manufacturing and commercializing TCR immunotherapies for the benefit of cancer patients, our shareholders, our employees, and our partners. By utilizing TCR-based therapeutics, we are able to direct T cells to intracellular cancer targets that are not accessible through classical antibody-based or CAR-T therapies. We believe that by identifying what we call true cancer targets and the right TCRs, we are well positioned to transform current solid tumor treatment paradigms by delivering cellular and bispecific product candidates that have the potential to substantially improve the lives of cancer patients.

We are developing our targeted immunotherapy product candidates through two distinct treatment modalities: TCR-engineered autologous (“ACTengine”) or allogeneic (“ACTallo”) Adoptive Cell Therapies (“ACT”) and antibody-like Bispecifics, also called T Cell Engaging Receptors (“TCER”). Each modality is designed with distinct attributes and mechanisms of action to produce the desired therapeutic effect for the targeted cancer patient populations.

Company and Corporate Information

We were incorporated as a Dutch private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) under the name Immatics B.V. on March 10, 2020 solely for the purpose of effectuating the business combination (the “Business Combination”) between us, ARYA Sciences Acquisition Corp., a Cayman Islands exempted company, Immatics Biotechnologies GmbH, a German limited liability company, Immatics Merger Sub 1, a Cayman Islands exempted company, and Immatics Merger Sub 2, a Cayman Islands exempted company. Upon the closing of the Business Combination on July 1, 2020, we converted into a Dutch public limited liability company (naamloze vennootschap) and changed our name to Immatics N.V.

We are registered in the Commercial Register of the Chamber of Commerce (Kamer van Koophandel) in the Netherlands under number 77595726. We have our corporate seat in Amsterdam, the Netherlands and our registered office is at Paul-Ehrlich-Straße 15, 72076 Tübingen, Federal Republic of Germany, and our telephone number is +49 (7071) 5397-0. Our executive office in the United States is located at Immatics US, Inc., 13203 Murphy Rd., Suite 100, Stafford, Texas 77477 and our telephone number is +1 (346) 204-5400. Our website is www.immatics.com. The reference to our website is an inactive textual reference only, and information contained therein or connected thereto is not incorporated into this prospectus or the registration statement of which it forms a part.

Implications of Being a Foreign Private Issuer

We are a “foreign private issuer.” Accordingly, we report under the Exchange Act of 1934, as amended (the “Exchange Act”), as a non-U.S. company with foreign private issuer status. This means that, as long as we qualify as a foreign private issuer under the Exchange Act, we will be exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including:

3

We may take advantage of these exemptions until such time as we are no longer a foreign private issuer. We would cease to be a foreign private issuer at such time as more than 50% of our outstanding voting securities are held by U.S. residents and any of the following three circumstances applies: (i) the majority of our executive officers or directors are U.S. citizens or residents, (ii) more than 50% of our assets are located in the United States or (iii) our business is administered principally in the United States.

In this prospectus and in the documents incorporated by reference in this prospectus, we have taken advantage of certain of the reduced reporting requirements as a result of being a foreign private issuer. Accordingly, the information contained in this prospectus and in the documents incorporated by reference in this prospectus may be different than the information you receive from other public companies in which you hold equity securities.

RISK FACTORS

Investing in our securities involves risk. Before making a decision to invest in our securities, you should carefully consider the risks described under “Risk Factors” in the applicable prospectus supplement and in our then-most recent Annual Report on Form 20-F, and any updates to those risk factors in our reports on Form 6-K incorporated by reference in this prospectus, together with all of the other information appearing or incorporated by reference in this prospectus and any applicable prospectus supplement, in light of your particular investment objectives and financial circumstances. Although we discuss key risks in our discussion of risk factors, new risks may emerge in the future, which may prove to be significant. We cannot predict future risks or estimate the extent to which they may affect our business, results of operations, financial condition and prospects.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference in this prospectus contain statements that constitute forward-looking statements within the meaning of Section 21E of the Exchange Act and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”). All statements other than statements of historical facts, including statements regarding our future results of operations and financial position, business and commercial strategy, potential market opportunities, products and product candidates, research pipeline, ongoing and planned preclinical studies and clinical trials, regulatory submissions and approvals, research and development costs, timing and likelihood of success, as well as plans and objectives of management for future operations, are forward-looking statements. Many of the forward-looking statements contained in this prospectus can be identified by the use of forward-looking words such as “anticipate,” “believe,” “could,” “expect,” “should,” “plan,” “intend,” “estimate,” “will” and “potential,” among others.

Forward-looking statements are based on our management’s beliefs and assumptions and on information available to our management at the time such statements are made. Such statements are subject to risks and uncertainties, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those identified in the “Risk Factors” section of this prospectus and in the documents incorporated by reference in this prospectus. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements, whether as a result of any new information, future events, changed circumstances or otherwise. You should read this prospectus, the documents incorporated by reference in this prospectus and the documents that we have filed as exhibits to the registration statement of which this prospectus is a part completely and with the understanding that our actual future results may be materially different from what we expect.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of such statements, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

5

USE OF PROCEEDS

Unless otherwise indicated in a prospectus supplement, the principal purpose of an offering of securities by us would be to increase our capitalization and financial flexibility and the net proceeds from our sale of the securities will be used for general corporate purposes and other business opportunities. Unless otherwise indicated in a prospectus supplement, we will not receive any proceeds from an offering of securities by a selling securityholder.

DIVIDEND POLICY

We have never declared or paid any cash dividends and have no plan to declare or pay any dividends on our ordinary shares in the foreseeable future. We currently intend to retain any earnings for future operations and expansion.

Since we are a holding company, our ability to pay dividends will be dependent upon the financial condition, liquidity and results of operations of, and the receipt of dividends, loans or other funds from, our subsidiaries. Our subsidiaries are separate and distinct legal entities and have no obligation to make funds available to us. In addition, there are various statutory, regulatory and contractual limitations and business considerations on the extent, if any, to which our subsidiaries may pay dividends, make loans or otherwise provide funds to us.

Under Dutch law, we may only pay dividends and other distributions from our reserves to the extent our shareholders’ equity (eigen vermogen) exceeds the sum of our paid-in and called-up share capital plus the reserves we must maintain under Dutch law or our articles of association and (if it concerns a distribution of profits) after adoption of our statutory annual accounts by our general meeting from which it appears that such dividend distribution is allowed. Subject to those restrictions, any future determination to pay dividends or other distributions from our reserves will be at the discretion of our board of directors and will depend upon a number of factors, including our results of operations, financial condition, future prospects, contractual restrictions, restrictions imposed by applicable law and other factors we deem relevant.

Under our articles of association, profits will be at the disposal of the general meeting at the proposal of our board of directors for distribution on our ordinary shares, subject to applicable restrictions of Dutch law. Our board of directors is permitted, subject to certain requirements and applicable restrictions of Dutch law, to declare interim dividends without the approval of our general meeting. Dividends and other distributions shall be made payable four weeks after they have been declared unless our general meeting determines another date at the proposal of our board of directors. Claims to dividends and other distributions not made within five years from the date that such dividends or distributions became payable will lapse and any such amounts will be considered to have been forfeited to us (verjaring).

DESCRIPTION OF SHARE CAPITAL AND ARTICLES OF ASSOCIATION

The Company

We were incorporated on March 10, 2020 as a private limited liability company (besloten vennootschap met beperkte aansprakelijkheid) under Dutch law, and upon the consummation of the Business Combination, we converted into a Dutch public limited liability company (naamloze vennootschap).

We are registered in the Commercial Register of the Chamber of Commerce (Kamer van Koophandel) in the Netherlands under number 77595726. We have our corporate seat in Amsterdam, the Netherlands and our registered office is at Paul-Ehrlich-Straße 15, 72076 Tübingen, Federal Republic of Germany.

Share Capital

Authorized Share Capital

Our authorized share capital consists of 285,000,000 ordinary shares, nominal value of €0.01 per share, and 15,000,000 financing preferred shares. The financing preferred shares are divided into five series, each consisting of 3,000,000 financing preferred shares.

The financing preferred shares may, at the request of the holder, be converted into ordinary shares pursuant to a resolution of our board of directors. The conditions for conversion and the further terms and conditions related to the financing preferred shares will be determined by our board of directors, our general meeting and the meeting of holders of the series of financing preferred shares concerned, if such series of financing preferred shares has been issued and are held by persons other than us. The preceding sentence applies by analogy to any adjustment to the conditions.

Changes in Our Share Capital

In this section, share amounts are presented as of the date of the relevant transaction. Since January 1, 2021, our share capital has changed as follows:

Issuance of Ordinary Shares

Under Dutch law, shares are issued and rights to subscribe for shares are granted pursuant to a resolution of our general meeting. Our articles of association provide that the general meeting may only resolve to issue shares upon the proposal of our board of directors. The general meeting may authorize our board of directors to issue new ordinary shares or grant rights to subscribe for ordinary shares. The authorization can be granted and extended, in each case for a period not exceeding five years. For as long as, and to the extent, that such authorization is effective, our general meeting will not have the power to issue ordinary shares.

7

Pursuant to a resolution of the general meeting dated June 20, 2024, our board of directors is irrevocably authorized for a period of five years from such date, to issue ordinary shares in the Company’s capital and/or to grant rights to subscribe for ordinary shares in the Company’s capital up to the authorized share capital as included in the Company’s articles of association from time to time.

Preemptive Rights

Subject to restrictions in our articles of association, holders of ordinary shares have preemptive rights in relation to newly issued ordinary shares under Dutch law.

Under our articles of association, the preemptive rights in respect of newly issued ordinary shares may be restricted or excluded by a resolution of our general meeting upon the proposal of our board of directors, which resolution requires a two-thirds majority of the votes cast if less than half of the issued share capital is present or represented at the meeting. The general meeting may authorize our board of directors to limit or exclude the preemptive rights in respect of newly issued ordinary shares, which resolution requires a two-thirds majority of the votes cast if less than half of the issued share capital is present or represented at the meeting. Such authorization for our board of directors can be granted and extended, in each case for a period not exceeding five years.

Pursuant to a resolution of the general meeting dated June 20, 2024, our board of directors is irrevocably authorized for a period of five years from such date to limit or exclude preemptive rights in relation to any issuance of ordinary shares in the Company’s capital or granting of rights to subscribe for such ordinary shares the Company’s capital up to the authorized share capital as included in the Company’s articles of association from time to time.

Preemptive rights do not exist with respect to (a) the issuance of ordinary shares or grant of rights to subscribe for ordinary shares to our employees or a “group” company of ours, and (b) the issuance of ordinary shares against a contribution in kind. Preemptive rights do not exist with respect to the issuance of financing preferred shares and holders of financing preferred shares have no preemptive right to acquire newly issued ordinary shares.

Transfer of Ordinary Shares

Under Dutch law, transfers of ordinary shares (other than in book-entry form) require a written deed of transfer and, unless the company is a party to the deed of transfer, and acknowledgement by or proper service upon the company to be effective.

Under our articles of association, if one or more ordinary shares are admitted to trading on Nasdaq or any other regulated foreign stock exchange located in the United States, we may, by resolution of our board of directors, determine that the laws of the State of New York will apply to the property law aspects of the ordinary shares included in the part of the register of shareholders kept by the relevant transfer agent. Such resolution, as well as the revocation thereof, will be made public as required by law and will be made available for inspection at our office and the Dutch trade register. Our management has adopted such resolution effective as of July 1, 2020.

Form of Ordinary Shares

Pursuant to our articles of association, the ordinary shares are registered shares.

Purchase and Repurchase of Ordinary Shares

Under Dutch law, we may not subscribe for newly issued ordinary shares. We may acquire ordinary shares, subject to applicable provisions and restrictions of Dutch law and our articles of association, to the extent that:

8

Other than ordinary shares acquired for no valuable consideration or under universal title of succession (onder algemene titel) (e.g., through a merger or spin-off) under statutory Dutch or other law, we may acquire ordinary shares only if our general meeting has authorized our board of directors to acquire ordinary shares. An authorization by our general meeting for the acquisition of ordinary shares can be granted for a maximum period of 18 months. Such authorization must specify the number of ordinary shares that may be acquired, the manner in which these shares may be acquired and the price range within which the shares may be acquired. No authorization of our general meeting is required if ordinary shares are acquired by us on Nasdaq with the intention of transferring such ordinary shares to our employees or employees of a group company pursuant to an arrangement applicable to them. We cannot derive any right to any distribution from ordinary shares, or voting rights attached to ordinary shares, acquired by us.

Pursuant to a resolution of the general meeting dated June 20, 2024, our board of directors is irrevocably authorized for a period of 18 months from such date to resolve for us to acquire fully paid-up ordinary shares or depositary receipts thereof up to the maximum number of ordinary shares permitted pursuant to applicable law and our articles of association from time to time, through repurchases negotiated in the open market or privately, in self-tender offers, or through accelerated repurchase arrangements, at prices ranging from the nominal value of the ordinary shares up to 110% of the market price of the ordinary shares, provided that: (i) for open market or privately negotiated repurchases, the market price shall be the price for ordinary shares on Nasdaq at the time the transaction is agreed upon by us, (ii) for self-tender offers, the market price shall be the volume weighted average price for the ordinary shares on Nasdaq during a period, determined by our board of directors, of no less than one and no more than five consecutive trading days immediately prior to the expiration of the tender offer, and (iii) for accelerated repurchase arrangements, the market price shall be the volume weighted average price of the ordinary shares on Nasdaq over the term of the arrangement; the volume weighted average price for any number of trading days shall be calculated as the arithmetic average of the daily volume weighted average price on those trading days.

Capital Reduction

At a general meeting, our shareholders may resolve on the proposal of our board of directors to reduce our issued share capital by (i) cancelling ordinary shares or (ii) reducing the nominal value of the ordinary shares by amending our articles of association. In either case, this reduction would be subject to applicable statutory provisions. A resolution to cancel ordinary shares may only relate to (i) ordinary shares held by us or in respect of which we hold the depository receipts, or (ii) all financing preferred shares of a class if approved by the holders of all shares of that class. In order to be approved by our general meeting, a resolution to reduce the capital requires a two-thirds majority of the votes cast if less than half of the issued share capital is present or represented at the meeting. A reduction of the nominal value of ordinary shares without repayment and without release from the obligation to pay up the ordinary shares must be effectuated proportionally on shares of the same class (unless all affected shareholders agree to a disproportional reduction).

A resolution that would result in a reduction of capital requires approval by a majority of the votes cast of each group of shareholders of the same class whose rights are prejudiced by the reduction. In addition, a reduction of capital involves a two-month waiting period during which creditors have the right to object to a reduction of capital under specified circumstances.

General Meeting of Shareholders and Voting Rights

General Meeting of Shareholders

General meetings are held in Amsterdam, Rotterdam, The Hague, Arnhem, Utrecht, or in the municipality of Haarlemmermeer (Schiphol Airport), the Netherlands. All of our shareholders and others entitled to attend our general meetings are authorized to address the meeting and, in so far as they have such right, to vote, either in person or by proxy.

We will hold at least one general meeting each year, to be held within six months after the end of our financial year. A general meeting will also be held within three months after our board of directors has determined it to be likely that our equity has decreased to an amount equal to or lower than half of its paid-up and called-up capital, in order to discuss the measures to be taken if so required. If our board of directors fails to hold such general meeting in a timely manner, each shareholder and other person entitled to attend our general meeting may be authorized by the Dutch court to convene our general meeting.

9

Our board of directors may convene additional extraordinary general meetings of shareholders at its discretion, subject to the notice requirements described below. Pursuant to Dutch law, one or more shareholders and/or others entitled to attend general meetings of shareholders, alone or jointly representing at least 10% of our issued share capital, may on their application be authorized by the Dutch court to convene a general meeting. The Dutch court will disallow the application if (i) the applicants have not previously requested in writing that our board of directors convenes a shareholders’ meeting, (ii) our board of directors convenes a shareholders’ meeting or (iii) our board of directors has taken the necessary steps so that the shareholders’ meeting could be held within six weeks after such request.

The general meeting is convened by a notice, which includes an agenda stating the items to be discussed and the location and time of our general meeting. For the annual general meeting, the agenda will include, among other things, the adoption of our annual accounts, the appropriation of its profits or losses and proposals relating to the composition of and filling of any vacancies on our board of directors. In addition, the agenda for a general meeting includes such additional items as determined by our board of directors. Pursuant to Dutch law, one or more shareholders and/or others entitled to attend general meetings of shareholders, alone or jointly representing at least 3% of the issued share capital, have the right to request the inclusion of additional items on the agenda of shareholders’ meetings. Such requests must be made in writing, and may include a proposal for a shareholder resolution, and must be received by us no later than on the sixtieth (60th) day before the day the relevant shareholders’ meeting is held. No resolutions will be adopted on items other than those which have been included in the agenda. Under our articles of association, certain items can only be put on the agenda as a voting item by our board of directors. Shareholders meeting the relevant requirements may still request the inclusion of such items on the agenda as a discussion item.

In accordance with the Dutch Corporate Governance Code, shareholders who have the right to put an item on the agenda for our general meeting or to request the convening of a general meeting shall not exercise such rights until after they have consulted our board of directors. If exercising such rights may result in a change in our strategy (for example, through the dismissal of one or more of our directors), our board of directors must be given the opportunity to invoke a reasonable period of up to 180 days to respond to the shareholders’ intentions. If invoked, our board of directors must use such response period for further deliberation and constructive consultation, in any event, with the shareholder(s) concerned and exploring alternatives. At the end of the response time, our board of directors shall report on this consultation and the exploration of alternatives to our general meeting. The response period may be invoked only once for any given general meeting and shall not apply (i) in respect of a matter for which a response period or a cooling-off period (as discussed below) has been previously invoked or (ii) if a shareholder holds at least 75% of our issued share capital as a consequence of a successful public bid.

Moreover, our board of directors can invoke a cooling-off period of up to 250 days when shareholders, using their right to have items added to the agenda for a general meeting or their right to request a general meeting, propose an agenda item for our general meeting to dismiss, suspend or appoint one or more directors (or to amend any provision in our articles of association dealing with those matters) or when a public offer for our company is made or announced without our support, provided, in each case, that our board of directors believes that such proposal or offer materially conflicts with the interests of our company and its business. During a cooling-off period, our general meeting cannot dismiss, suspend or appoint directors (or amend the provisions in our articles of association dealing with those matters) except at the proposal of our board of directors. During a cooling-off period, our board of directors must gather all relevant information necessary for a careful decision-making process and at least consult with shareholders representing 3% or more of our issued share capital at the time the cooling-off period was invoked, as well as with our Dutch works council (if we or, under certain circumstances, any of our subsidiaries would have one). Formal statements expressed by these stakeholders during such consultations must be published on our website to the extent these stakeholders have approved that publication. Ultimately one week following the last day of the cooling-off period, our board of directors must publish a report in respect of its policy and conduct of affairs during the cooling-off period on our website. This report must remain available for inspection by shareholders and others with meeting rights under Dutch law at our office and must be tabled for discussion at the next general meeting. Shareholders representing at least 3% of our issued share capital may request the Enterprise Chamber for early termination of the cooling-off period. The Enterprise Chamber must rule in favor of the request if the shareholders can demonstrate that:

10

We will give notice of each general meeting by publication on our website and, to the extent required by applicable law, in a Dutch daily newspaper with national distribution, and in any other manner that we may be required to follow in order to comply with Dutch law and applicable stock exchange and SEC requirements. We will observe the statutory minimum convening notice period for a general meeting. Holders of registered shares may further be provided notice of the meeting in writing at their addresses as stated in its shareholders’ register.

Pursuant to our articles of association and Dutch law, our board of directors may determine a record date (registratiedatum) of 28 calendar days prior to a general meeting to establish which shareholders and others with meeting rights are entitled to attend and, if applicable, vote at our general meeting. The record date, if any, and the manner in which shareholders can register and exercise their rights will be set out in the notice of our general meeting. Our articles of association provide that a shareholder must notify us in writing of his or her identity and his or her intention to attend (or be represented at) our general meeting, such notice to be received by us on the date set by our board of directors in accordance with our articles of association and as set forth in the convening notice. If this requirement is not complied with or if upon request no proper identification is provided by any person wishing to enter our general meeting, the chairman of our general meeting may, in his or her sole discretion, refuse entry to the shareholder or his or her proxy holder.

Pursuant to our articles of association, our general meeting is chaired by the chairman of our board of directors, who, nevertheless, may charge another person to preside over the meeting in his place even if he himself is present at the meeting. If the chairman of our board of directors is absent and he has not charged another person to preside over the meeting in his place, our directors present at the meeting will appoint one of them to be chairman. In the absence of all directors, our general meeting will appoint its chairman.

Voting Rights and Quorum

In accordance with Dutch law and our articles of association, each ordinary share, irrespective of which class it concerns, confers the right on the holder thereof to cast one vote at our general meeting. The voting rights attached to any ordinary shares held by us or our direct or indirect subsidiaries are suspended, unless the ordinary shares were encumbered with a right of usufruct or a pledge in favor of a party other than us or a direct or indirect subsidiary before such ordinary shares were acquired by us or such a subsidiary, in which case, the other party may be entitled to exercise the voting rights on the ordinary shares. We may not exercise voting rights for ordinary shares in respect of which we or a direct or indirect subsidiary has a right of usufruct or a pledge.

Voting rights may be exercised by shareholders or by a duly appointed proxy holder (the written proxy being acceptable to the chairman of our general meeting) of a shareholder, which proxy holder need not be a shareholder. The holder of a usufruct or pledge on shares will have the voting rights attached thereto if so provided for when the usufruct or pledge was created.

Under our articles of association, blank votes (votes where no choice has been made), abstentions and invalid votes will not be counted as votes cast. However, shares in respect of which a blank vote or invalid vote has been cast and shares in respect of which the person with meeting rights who is present or represented at the meeting has abstained from voting are counted when determining the part of the issued share capital that is present or represented at a general meeting. The chairman of our general meeting will determine the manner of voting and whether voting may take place by acclamation.

Resolutions of the shareholders are adopted at a general meeting by a majority of votes cast, except where Dutch law or our articles of association provide for a special majority in relation to specified resolutions. Our articles of association do not provide for a quorum requirement, subject to any provision of mandatory Dutch law.

Subject to certain restrictions in our articles of association, the determination during our general meeting made by the chairman of that general meeting with regard to the results of a vote will be decisive. Our board of directors will keep a record of the resolutions passed at each general meeting.

11

Amendment of Articles of Association

At a general meeting, at the proposal of our board of directors, our general meeting may resolve to amend the articles of association. A resolution by the shareholders to amend the articles of association requires a majority of the votes cast.

Merger, Demerger and Dissolution

At the proposal of our board of directors, our general meeting may resolve with a majority of the votes cast (subject to certain exceptions), or with at least two-thirds of the votes cast if less than half of the issued capital is present or represented at our general meeting, to legally merge or demerge the company within the meaning of Title 7, Book 2 of the Dutch Civil Code.

Our shareholders may at a general meeting, based on a proposal by our board of directors, by means of a resolution passed by a majority of the votes cast, resolve that the company will be dissolved. In the event of dissolution of the company, the liquidation will be effected by our executive directors, under the supervision of our non-executive directors, unless our general meeting decides otherwise.

Squeeze-Out

A shareholder who for its own account (or together with its group companies) holds at least 95% of our issued share capital may institute proceedings against the other shareholders jointly for the transfer of their shares to the shareholder who holds such 95% majority. The proceedings are held before the Enterprise Chamber of the Amsterdam Court of Appeal (Ondernemingskamer van het Gerechtshof Amsterdam) (the “Enterprise Chamber”) and can be instituted by means of a writ of summons served upon each of the minority shareholders in accordance with the provisions of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering). The Enterprise Chamber may grant the claim for squeeze-out in relation to all minority shareholders and will determine the price to be paid for the shares, if necessary, after appointment of one or three experts who will offer an opinion to the Enterprise Chamber on the value of the shares of the minority shareholders. Once the order to transfer by the Enterprise Chamber becomes final and irrevocable, the majority shareholder that instituted the squeeze-out proceedings will give written notice of the date and place of payment and the price to the holders of the shares to be acquired whose addresses are known to the majority shareholder. Unless the addresses of all minority shareholders are known to the majority shareholder acquiring the shares, the majority shareholder is required to publish the same in a newspaper with a national circulation.

A shareholder that holds a majority of our issued share capital, but less than the 95% required to institute the squeeze-out proceedings described above, may seek to propose and implement one or more restructuring transactions with the objective of obtaining at least 95% of our issued share capital so the shareholder may initiate squeeze-out proceedings. Those restructuring transactions could, among other things, include a merger or demerger involving the company, a contribution of cash and/or assets against issuance of ordinary shares, the issuance of new ordinary shares to the majority shareholder without preemptive rights for minority shareholders or an asset sale transaction.

Depending on the circumstances, an asset sale of a Dutch public limited liability company (naamloze vennootschap) or a triangular legal merger (driehoeksfusie) of a Dutch public limited liability company (naamloze vennootschap) with and into a subsidiary followed by a share sale of that subsidiary (as legal successor to the Dutch public limited liability company (naamloze vennootschap) concerned) is sometimes used as a way to squeeze out minority shareholders, for example, after a successful tender offer through which a third party acquires a supermajority, but less than all, of the company’s shares. In such scenarios, either (a) the business of the target company is sold to a third party or a special purpose vehicle, followed by the liquidation of the target company or (b) the shares in the legal successor to the target company is sold to a third party or a special purpose vehicle, followed by the liquidation of the holding vehicle of such legal successor. The purchase price is distributed to all shareholders in proportion to their respective shareholding as liquidation proceeds, thus separating the business from the company in which minority shareholders had an interest.

Any sale or transfer of all of our assets and our dissolution or liquidation is subject to approval by a majority of the votes cast in our general meeting. Our articles of association provide that our general meeting may only adopt such resolution upon a proposal of our board of directors.

12

Certain Other Major Transactions

Our articles of association and Dutch law provide that resolutions of our board of directors concerning a material change in our identity, character or business are subject to the approval of our general meeting. Such changes include:

Dividends and Other Distributions

We may only make distributions to our shareholders if our equity exceeds the aggregate amount of the issued share capital and the reserves that must be maintained pursuant to Dutch law or our articles of association. We may not make any distribution of profits on shares held by the company as treasury shares and such treasury shares will not be taken into account when determining the profit entitlement of our shareholders, unless such treasury shares are encumbered with a right of usufruct or a right of pledge. Under our articles of association, any profits or distributable reserves must first be applied to pay a dividend on the financing preferred shares, if outstanding.

Any remaining profits may be reserved by our board of directors. After reservation by our board of directors of any distributable profits, our general meeting will be authorized to declare distributions on the proposal of our board of directors. Our board of directors is permitted, subject to certain requirements, to declare interim dividends without the approval of the shareholders. Interim dividends may be declared as provided in our articles of association and may be distributed to the extent that the shareholders’ equity, based on interim financial statements, exceeds the paid-up and called-up share capital and the reserves that must be maintained under Dutch law or our articles of association. We may reclaim any distributions, whether interim or not interim, made in contravention of certain restrictions of Dutch law from shareholders that knew or should have known that such distribution was not permissible. In addition, on the basis of Dutch case law, if after a distribution we are not able to pay its due and collectable debts, then our shareholders or directors who at the time of the distribution knew or reasonably should have foreseen that result may be liable to its creditors.

Upon proposal of our board of directors, the general meeting may determine that distributions will be made in whole or in part in a currency other than the euro. We shall announce any proposal for a distribution and the date when and the place where the distribution will be payable to all shareholders by electronic means of communication with due observance of the applicable law and stock exchange rules. Claims for payment of dividends and other distributions not made within five years from the date that such dividends or distributions became payable will lapse, and any such amounts will be considered to have been forfeited to the company (verjaring).

Notices

We will give notice of each general meeting by publication on our website and, to the extent required by applicable law, in a Dutch daily newspaper with national distribution, and in any other manner that we may be required to follow in order to comply with Dutch law and applicable stock exchange and SEC requirements. Holders of registered shares may further be provided notice of the meeting in writing at their addresses as stated in our shareholders’ register.

Registration Rights

We have granted to certain of our securityholders registration rights pursuant to an Investor Rights and Lock-Up Agreement, dated July 1, 2020, among us and the investors party thereto. Such securityholders are entitled to the following rights with respect to the registration of their ordinary shares for public resale under the Securities Act.

13

Shelf Registration. We are obligated to file and keep effective a shelf registration statement pursuant to Rule 415 under the Securities Act with respect to all securities subject to registration rights, subject to certain exceptions.

Demand Registration. Upon the demand of certain securityholders, we are obligated to effect a resale registration under the Securities Act with respect to all or any portion of their shares subject to registration rights, subject to certain exceptions. Demand registration rights will not be triggered if there is an effective resale shelf registration statement.

Piggyback Registration. In the event that we propose to register any of our securities under the Securities Act, either for our account or for the account of our other securityholders, holders will be entitled to certain piggyback registration rights allowing each to include its shares in the registration, subject to certain marketing and other limitations. As a result, whenever we propose to file a registration statement under the Securities Act, other than with respect to a demand registration, a registration statement on Form S-4, F-4 or S-8 or a registration of convertible debt securities, these holders will be entitled to notice of the registration and will have the right to include their registrable securities in the registration, subject to certain limitations. Piggyback registration rights will not be triggered if there is an effective resale shelf registration statement, the registration is solely for an offering of securities by us and no other securityholder is entitled to participate in such registration.

Expenses; Indemnification. We must pay all registration expenses in connection with effecting any demand registration, piggyback registration or shelf registration. We are also subject to customary indemnification and contribution provisions.

Stock Exchange Listing

Our ordinary shares are listed on Nasdaq under the symbol “IMTX.”

Transfer Agent

Continental Stock Transfer & Trust Company serves as our agent in New York to maintain our shareholders’ register on behalf of our board of directors and acts as transfer agent and registrar for the ordinary shares.

Exchange Controls

Under Dutch law, there are no exchange controls applicable to the transfer to persons outside of the Netherlands of dividends or other distributions with respect to, or of the proceeds from the sale of, shares of a Dutch company, subject to applicable restrictions under sanctions and measures, including those concerning export control, pursuant to applicable resolutions adopted by the United Nations, regulations of the European Union, the Dutch Sanctions Act 1977 (Sanctiewet 1977), national emergency legislation, or other legislation, applicable anti-boycott regulations and similar rules and provided that, under certain circumstances, payments of such dividends or other distributions must be reported to the Dutch Central Bank at their request for statistical purposes. There are no special restrictions in our articles of association or Dutch law that limit the right of shareholders who are not citizens or residents of the Netherlands to hold or vote shares. The European Directive Mandatory Disclosure Rules (2011/16/EU) in relation to cross-border tax arrangements can provide for future notification requirements.

Under German law, there are no exchange controls restricting the transfer of funds between Germany and other countries or individuals, subject to applicable restrictions concerning import or export control or sanctions and measures against certain persons, entities and countries subject to embargoes in accordance with German law and applicable resolutions adopted by the United Nations and the European Union.

Under German foreign trade regulation, with certain exceptions, every corporation or individual residing in Germany must report to the German Central Bank on any payment received from or made to a non-resident corporation or individual if the payment exceeds €12,500 (or the equivalent in a foreign currency). Additionally, corporations and individuals residing in Germany must report to the German Central Bank on any claims of a resident against, or liabilities payable to, a non-resident corporation or individual exceeding an aggregate of €5 million (or the equivalent in a foreign currency) at the end of any calendar month. Resident corporations and individuals are also required to report annually to the German Central Bank on any stakes of 10% or more they hold in the equity of non-resident

14

corporations with total assets of more than €3 million. Corporations residing in Germany with assets in excess of €3 million must report annually to the German Central Bank on any stake of 10% or more in the company held by an individual or a corporation located outside Germany.

15

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities, which may be secured or unsecured and may be exchangeable for and/or convertible into other securities, including our ordinary shares. The debt securities will be issued under one or more separate indentures between us and a designated trustee. The terms of each series of debt securities being offered, including the terms, if any, on which a series of debt securities may be convertible into or exchangeable for other securities, and the material terms of the indenture will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will set forth, to the extent required, the following terms of the debt securities in respect of which the prospectus supplement is delivered:

16

DESCRIPTION OF WARRANTS

We may issue warrants to purchase our debt or equity securities. The warrants may be issued independently or together with any other securities and may be attached to, or separate from, such securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a warrant agent. The terms of any warrants being offered and a description of the material provisions of the applicable warrant agreement will be set forth in the applicable prospectus supplement.

The applicable prospectus supplement will set forth, to the extent required, the following terms of the warrants in respect of which the prospectus supplement is delivered:

17

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase our debt or equity securities. The subscription rights may be issued independently or together with any other securities, may be attached to, or separate from, such securities and may or may not be transferable by the shareholder receiving the subscription rights. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any unsubscribed securities after such offering. The terms of any subscription rights being offered will be set forth in the applicable prospectus supplement.

If fewer than all of the subscription rights issued in any rights offering are exercised, we may offer any unsubscribed securities directly to persons other than shareholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby arrangements, as described in the applicable prospectus supplement.

The applicable prospectus supplement will set forth, to the extent required, the following terms of the subscription rights in respect of which the prospectus supplement is delivered:

18

DESCRIPTION OF PURCHASE CONTRACTS

We may issue purchase contracts for the purchase or sale of debt or equity securities issued by us or securities of third parties, a basket of such securities, an index or indices of such securities or any combination of the above as specified in the applicable prospectus supplement, currencies or commodities.

Each purchase contract will entitle the holder thereof to purchase or sell, and obligate us to sell or purchase, on specified dates, such securities, currencies or commodities at a specified purchase price, which may be based on a formula, all as set forth in the applicable prospectus supplement. A purchase by us or any of our subsidiaries of ordinary shares pursuant to any such purchase contract shall be subject to certain restrictions under Dutch law that generally apply to a repurchase of shares. We may, however, satisfy our obligations, if any, with respect to any purchase contract by delivering the cash value of such purchase contract or the cash value of the property otherwise deliverable or, in the case of purchase contracts on underlying currencies, by delivering the underlying currencies, as set forth in the applicable prospectus supplement. The applicable prospectus supplement will also specify the methods by which the holders may purchase or sell such securities, currencies or commodities and any acceleration, cancellation or termination provisions or other provisions relating to the settlement of a purchase contract.

The purchase contracts may require us to make periodic payments to the holders thereof or vice versa, which payments may be deferred to the extent set forth in the applicable prospectus supplement, and those payments may be unsecured or prefunded on some basis. The purchase contracts may require the holders thereof to secure their obligations in a specified manner to be described in the applicable prospectus supplement. Alternatively, purchase contracts may require holders to satisfy their obligations thereunder when the purchase contracts are issued. Our obligation to settle such pre-paid purchase contracts on the relevant settlement date may constitute indebtedness. Accordingly, pre-paid purchase contracts will be issued under an indenture.

19

DESCRIPTION OF UNITS

As specified in the applicable prospectus supplement, we may issue units consisting of one or more purchase contracts, warrants, debt securities, ordinary shares or any combination of such securities. The applicable supplement will describe:

20

FORMS OF SECURITIES

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities will be issued in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue registered debt securities, warrants and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action,

21

and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of Immatics N.V., the trustees, the warrant agents, the unit agents or any other agent of Immatics N.V., agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

22

The validity of certain securities and certain matters with respect to U.S. federal and New York State law will be passed upon for us by Davis Polk & Wardwell LLP, New York, New York. Any underwriters, dealers or agents will be advised by their own legal counsel concerning issues relating to any offering.

EXPERTS

The financial statements and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Annual Report on Internal Control over Financial Reporting) incorporated in this prospectus by reference to the Annual Report on Form 20-F for the year ended December 31, 2023 have been so incorporated in reliance on the report of PricewaterhouseCoopers GmbH Wirtschaftsprüfungsgesellschaft, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting. PricewaterhouseCoopers GmbH Wirtschaftsprüfungsgesellschaft is a member of the Chamber of Public Accountants (Wirtschaftsprüferkammer), Berlin, Germany.

24

ENFORCEMENT OF CIVIL LIABILITIES

We are organized and existing under the laws of the Netherlands. As such, under Dutch private international law, the rights and obligations of our shareholders vis-à-vis the Company originating from Dutch corporate law and our articles of association, as well as the civil liability of our officers (functionarissen) (including our directors and executive officers) are governed in certain respects by the laws of the Netherlands.

We are not a resident of the United States and our officers may also not all be residents of the United States. As a result, depending on the subject matter of the action brought against us and/or our officers, United States courts may not have jurisdiction. If a Dutch court has jurisdiction with respect to such action, that court will apply Dutch procedural law and Dutch private international law to determine the law applicable to that action. Depending on the subject matter of the relevant action, a competent Dutch court may apply another law than the laws of the United States.

Also, service of process against non-residents of the United States can in principle (absent, for example, a valid choice of domicile) not be effected in the United States.

Furthermore, a substantial amount of our assets are located outside the United States. As of the date of this prospectus, (i) there is no treaty in force between the United States and the Netherlands for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters and (ii) both the Hague Convention on Choice of Court Agreements (2005) and the Hague Judgments Convention (2019) have entered into force for the Netherlands, but have not entered into force for the United States. Consequently, a judgment rendered by a court in the United States will not automatically be recognized and enforced by the competent Dutch courts. However, if a person has obtained a judgment rendered by a court in the United States that is enforceable under the laws of the United States and files a claim with the competent Dutch court, the Dutch court will in principle give binding effect to that United States judgment if (i) the jurisdiction of the United States court was based on a ground of jurisdiction that is generally acceptable according to international standards, (ii) the judgment by the United States court was rendered in legal proceedings that comply with the Dutch standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging), (iii) binding effect of such United States judgment is not contrary to Dutch public order (openbare orde) and (iv) the judgment by the United States court is not incompatible with a decision rendered between the same parties by a Dutch court, or with a previous decision rendered between the same parties by a foreign court in a dispute that concerns the same subject and is based on the same cause, provided that the previous decision qualifies for recognition in the Netherlands. Even if such a United States judgment is given binding effect, a claim based thereon may, however, still be rejected if the United States judgment is not or no longer formally enforceable. Moreover, if the United States judgment is not final (for instance when appeal is possible or pending) a competent Dutch court may postpone recognition until the United States judgment will have become final, refuse recognition under the understanding that recognition can be asked again once the United States judgment will have become final, or impose as a condition for recognition that security is posted.

A competent Dutch court may deny the recognition and enforcement of punitive damages or other awards. Moreover, a competent Dutch court may reduce the amount of damages granted by a United States court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Finally, there may be specific other instances, including pursuant to anti-boycott rules and regulations, where Dutch law prohibits the recognition and enforcement of a United States judgment. Thus, United States investors may not be able to enforce, or may experience difficulty in enforcing, a judgment obtained in a United States court against us or our officers.
