PROSPECTUS SUPPLEMENT

(To Prospectus dated February 27, 2023)

Hess Midstream LP

10,000,000 Class A Shares Representing Limited Partner Interests

The selling shareholder identified in this prospectus supplement is selling an aggregate of 10,000,000 Class A shares (the “Class A Shares”) representing limited partner interests in Hess Midstream LP (the “Company,” “HESM,” “we,” “our” or “us”). We will not receive any proceeds from the sale of the Class A Shares in this offering.

Our Class A Shares are traded on the New York Stock Exchange (“NYSE”) under the symbol “HESM.” The last reported sales price of our Class A Shares on the NYSE on February 2, 2024 was $34.23 per share.

The selling shareholder has granted the underwriters the option to purchase up to an aggregate of 1,500,000 additional Class A Shares from the selling shareholder on the same terms and conditions noted below within 30 days of the date of this prospectus supplement to cover over-allotments, if any. See “Selling Shareholder” beginning on page S-12.

Investing in our securities involves risk. Limited partner interests are inherently different from capital stock of a corporation. See “Risk Factors” beginning on page S-10 of this prospectus supplement and on page 7 of the accompanying base prospectus and the other risk factors incorporated by reference into this prospectus supplement and the accompanying base prospectus.

In this prospectus supplement, if there is only one underwriter, the term “underwriters” shall mean either the singular or plural as the context require.

The underwriters have agreed to purchase the shares of Class A common stock at a price of $     per share, which will result in approximately $     million of aggregate net proceeds before expenses to the selling stockholder (assuming no exercise of the underwriters’ option to purchase additional Class A Shares). The shares may be offered by the underwriters from time to time to purchasers directly or through agents, or through brokers in brokerage transactions on the NYSE, in the over-the-counter market, or to dealers in negotiated transactions or in a combination of such methods of sale, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. See “Underwriting” for a description of the compensation payable to the underwriters.

Delivery of the Class A Shares will be made on or about     , 2024 through the book-entry facilities of the Depository Trust Company.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved these securities or determined if this prospectus supplement or the accompanying base prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of this offering. The second part, the accompanying base prospectus, gives more general information, some of which may not apply to this offering. Generally, when we use the term “prospectus,” we are referring to both parts combined. You should read this entire prospectus supplement and the accompanying base prospectus, as well as the documents incorporated by reference herein and therein that are described under “Where You Can Find More Information” in this prospectus supplement and in the accompanying base prospectus. In the event that the information varies between this prospectus supplement and the accompanying base prospectus, you should rely on the information contained in this prospectus supplement.

In making an investment decision, prospective investors must rely on their own examination of the Company and the terms of the offering, including the merits and risks involved. Prospective investors should not construe anything in this prospectus as legal, business or tax advice. Each prospective investor should consult its own advisors as needed to make its investment decision and to determine whether it is legally permitted to purchase the securities under applicable laws and regulations.

We have not authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus supplement and the accompanying base prospectus, or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. We will not make an offer to sell the Class A Shares in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus supplement and the accompanying base prospectus is accurate only as of the date on its respective cover, that the information appearing in any applicable free writing prospectus is accurate only as of the date of that free writing prospectus, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates.

Additional information, including our financial statements and the notes thereto, is incorporated in this prospectus supplement and the accompanying base prospectus by reference to our reports filed with the Securities and Exchange Commission (the “SEC”). Please read “Where You Can Find More Information” in this prospectus supplement and in the accompanying base prospectus.

Although we believe these sources are reliable, we do not guarantee the accuracy or completeness of this information and we have not independently verified this information. In addition, the market and industry data and forecasts that may be included or incorporated by reference in this prospectus supplement, the accompanying base prospectus or any applicable free writing prospectus may involve estimates, assumptions and other risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” contained in this prospectus supplement, the accompanying base prospectus and any applicable free writing prospectus, and under similar headings in other documents that are incorporated by reference into this prospectus supplement and the accompanying base prospectus.

FORWARD-LOOKING STATEMENTS

This prospectus and prospectus supplement contain “forward-looking statements” within the meaning of U.S. federal securities laws. Words such as “anticipate,” “estimate,” “expect,” “forecast,” “guidance,” “could,” “may,” “should,” “would,” “believe,” “intend,” “project,” “plan,” “predict,” “will,” “target” and similar expressions identify forward-looking statements, which are not historical in nature. Our forward-looking statements may include, without limitation: our future financial and operational results; our business strategy; our industry; our expected revenues; our future profitability; our maintenance or expansion projects; our projected budget and capital expenditures and the impact of such expenditures on our performance; future economic and market conditions in the oil and gas industry; and expected timing and completion of the Chevron Merger (as defined below).

Forward-looking statements are based on our current understanding, assessments, estimates and projections of relevant factors and reasonable assumptions about the future. Forward-looking statements are subject to certain known and unknown risks and uncertainties that could cause actual results to differ materially from our historical experience and our current projections or expectations of future results expressed or implied by these forward-looking statements. The following important factors could cause actual results to differ materially from those in our forward-looking statements:

S-iii

S-iv

As and when made, we believe that our forward-looking statements are reasonable. However, given these risks and uncertainties, caution should be taken not to place undue reliance on any such forward-looking statements since such statements speak only as of the date when made and there can be no assurance that such forward-looking statements will occur and actual results may differ materially from those contained in any forward-looking statement we make. Except as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether because of new information, future events or otherwise.

RISK FACTORS

An investment in our Class A Shares involves risks. Limited partner interests are inherently different from capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in similar businesses. We urge you to carefully consider the information included under “Risk Factors” beginning on page 7 of the accompanying base prospectus and in our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, which are incorporated by reference into this prospectus supplement and the accompanying base prospectus, together with all of the other information included in this prospectus supplement and the accompanying base prospectus and the documents we incorporate by reference, in evaluating an investment in our Class A Shares.

If any of these risks were to materialize, our business, financial condition, results of operations and cash flows could be materially and adversely affected and you could lose all or part of your investment. Please also read “Forward-Looking Statements.” The risks described below and those incorporated by reference into this prospectus supplement and the accompanying base prospectus are not the only ones facing us. Additional risks not presently known to us or which we currently consider immaterial also may adversely affect us.

USE OF PROCEEDS

The selling shareholder identified in this prospectus supplement is selling all of the Class A Shares being sold in this offering, including any Class A Shares that may be sold in connection with the underwriters’ option to purchase additional shares. Accordingly, we will not receive any proceeds from the sale of our Class A Shares in this offering. We will bear all costs, fees and expenses in connection with this offering, except that the selling shareholder will pay all of its underwriting discounts and commissions. See “Selling Shareholder” and “Underwriting.”

S-11

SELLING SHAREHOLDER

The following table presents information regarding the selling shareholder in this offering, the Class A Shares that the underwriters have agreed to purchase from the selling shareholder and the Class A Shares subject to the underwriters’ option to purchase additional shares from the selling shareholder. We have paid all expenses relating to the registration of the shares by the selling shareholder under the Securities Act of 1933 (as amended, the “Securities Act”) and will pay other offering expenses, except that the selling shareholder will pay all underwriting discounts and commissions. We will not receive any proceeds from the sale of our Class A Shares by the selling shareholder.

We prepared the table based on information provided to us by the selling shareholder. We have not sought to verify such information.

Except as otherwise indicated, we believe that the selling shareholder has sole voting and dispositive power with respect to the shares indicated as beneficially owned.

S-12

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The tax consequences to you of an investment in our Class A Shares will depend in part on your own tax circumstances. Please read the risk factors included under the caption “Risk Factors” in our most recent Form 10-K and Quarterly Reports on Form 10-Q, which are incorporated by reference into this prospectus supplement and the base prospectus filed with the SEC on February 27, 2023, as well as the discussion of the principal U.S. federal income tax considerations associated with our operations and the purchase, ownership and disposition of our Class A Shares under the caption “Material U.S. Federal Income Tax Consequences to Non-U.S. Holders” in the base prospectus. You are urged to consult with your own tax advisor about the U.S. federal, state, local and foreign income tax consequences particular to your circumstances.

S-13

UNDERWRITING

The Company, the selling shareholder and the underwriters named below have entered into an underwriting agreement with respect to the Class A Shares being offered. Subject to certain conditions, each underwriter has severally agreed to purchase the number of Class A Shares indicated in the following table. Citigroup Global Markets Inc. is the representative of the underwriters.

The underwriters are collectively referred to as the “underwriters.” To the extent there is one underwriter, “underwriters” refers to the underwriter listed in the table above. The underwriters are committed to take and pay for all of the Class A Shares being offered, if any are taken, other than the Class A Shares covered by the option described below unless and until this option is exercised.

The underwriters have an option to buy up to an additional 1,500,000 Class A Shares from the selling shareholder. They may exercise that option for 30 days after the date of this prospectus supplement. If any Class A Shares are purchased pursuant to this option, the underwriters will severally purchase Class A Shares in approximately the same proportion as set forth in the table above. If any additional Class A Shares are purchased pursuant to this option, the underwriters will offer the additional shares on the same terms as those on which the Class A Shares are being offered.

The underwriters are purchasing the Class A Shares from the selling shareholder at a price of $    per share. The underwriters propose to offer the Class A Shares for sale from time to time in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt of acceptance by them and subject to their right to reject any order in whole or in part. The underwriters may effect such transactions by selling the Class A Shares to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or purchasers of the Class A Shares for whom they may act as agents or to whom they may sell as principal. The difference between the price at which the underwriters purchase Class A Shares and the price at which the underwriters resell such Class A Shares may be deemed underwriting compensation.

Sales of any Class A Shares made outside of the U.S. may be made by affiliates of the underwriters.

The Company and the selling shareholder estimate that their share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $500,000.

The Company and the selling shareholder have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act.

No Sales of Similar Securities

The Company, our general partner, the general partner of our general partner, the selling shareholder and Hess Investments North Dakota LLC have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any of their Class A Shares or securities convertible into or exchangeable for Class A Shares during the period from the date of this prospectus continuing through the date 60 days after the date of this prospectus (the “Lock-up Period”), except with the prior written consent of the representatives.

S-14

Notwithstanding the foregoing, and subject to the following conditions and the terms and conditions set forth in a “lock-up” agreement with the underwriters (the “Lock-Up Agreement”), the selling shareholder and Hess Investments North Dakota LLC may, as applicable: (i) transfer their Class A Shares as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth in the Lock-Up Agreement; (ii) transfer their Class A Shares to any trust for the direct or indirect benefit of the transferor or the immediate family of the transferor; provided that (a) the trustee of the trust agrees to be bound in writing by the restrictions set forth in the Lock-Up Agreement and (b) any such transfer shall not involve a disposition for value; (iii) transfer and surrender (a) Class B Units to the Partnership or the Company and (b) Class B Shares to the Company, in each case pursuant to the partnership agreement of the Partnership, in exchange for Class A Shares; provided that, for the avoidance of doubt, any Class A Shares received in such transfers shall be subject to the restrictions set forth in the Lock-Up Agreement; (iv) exercise or vest options or any other equity-based award, in each case under the Company’s equity incentive plan or any other plan or agreement described in this prospectus or the filings incorporated herein by reference, including any dispositions in connection with the “cashless” exercise of stock options and any open market transactions in connection with the payment of taxes due upon such exercise or vesting, provided that any such Class A Shares received upon such exercise or vesting will also be subject to the restrictions set forth in the Lock-Up Agreement; (v) transfer their Class A Shares by testate or intestate succession; provided that the transferee agrees in writing to be bound by the restrictions set forth in the Lock-Up Agreement; (vi) transfer their Class A Shares, Class B Units or Class B Shares as a distribution to their respective limited partners, members, stockholders or other similar equityholders, provided that (a) any such transfer shall not involve a disposition for value, (b) no filing under Section 16(a) of the Securities Exchange Act of 1934 (as amended, the “Exchange Act”) or other public disclosure reporting a reduction in beneficial ownership of securities of the Company shall be required or shall be voluntarily made during the Lock-Up Period and (c) the transferee agrees in writing to be bound by the restrictions set forth in the Lock-Up Agreement; (vii) transfer their Class A Shares, Class B Units or Class B Shares to their respective affiliates or to any investment fund or other entity they control or manage; provided that (a) any such transfer shall not involve a disposition for value, (b) no filing under Section 16(a) of the Exchange Act or other public disclosure reporting a reduction in beneficial ownership of securities of the Company shall be required or shall be voluntarily made during the Lock-Up Period and (c) the transferee agrees in writing to be bound by the restrictions set forth in the Lock-Up Agreement; (viii) transfer their Class B Units or Class B Shares to third parties; provided that (a) the transferee agrees in writing to be bound by the restrictions set forth in the Lock-Up Agreement and the transferee shall not redeem or exchange such Class B Units or Class B Shares for Class A Shares during the Lock-Up Period and (b) any filing under Section 16(a) of the Exchange Act by the transferor resulting from such transfer will note that the transferee is subject to the restrictions set forth in the Lock-Up Agreement; (ix) transfer their Class A Shares with the prior written consent of the representatives on behalf of the underwriters; and (x) transfer Class B Units and/or Class B Shares held by the selling shareholder or Hess Investments North Dakota LLC to the Company or the Partnership in a privately negotiated transaction.

Notwithstanding the foregoing, and subject to the following conditions and the terms and conditions set forth in the underwriting agreement, we may: (i) issue Class A Shares (which, for the avoidance of doubt, shall be subject to the transfer restrictions set forth in the underwriting agreement) upon the exchange or redemption of Class B Units and Class B Shares; (ii) issue equity-based awards under our equity incentive plan or any other plan or agreement described in this prospectus or the filings incorporated herein by reference; provided that any such Class A Shares issued in connection with this clause (ii) shall be subject to the transfer restrictions set forth in the underwriting agreement; (iii) issue and sell Class A Shares or securities convertible into or exchangeable or redeemable for Class A Shares as payment for any part of the purchase price for businesses that are acquired by us or our affiliates or any third parties in one transaction or a series of related transactions, or the filing or confidential submission of a registration statement relating to such securities; provided that (a) no greater than 5% of the outstanding number of Class A Shares (or securities convertible into or exchangeable or redeemable for the same) are issued and sold in accordance with this clause (iii), (b) such 5% limit shall not apply to issuances and sales of Class B Units and Class B Shares to Hess or its affiliates (as defined in Rule 405 under the Securities Act) and (c) any recipient of such Class A Shares or securities convertible into or exchangeable or

S-15

redeemable for Class A Shares, including Class B Units and Class B Shares, must agree in writing to be bound by the transfer restrictions set forth in the underwriting agreement for the remaining term of the Lock-Up Period; and (iv) publicly disclose any transaction that involves any of the actions permitted in this paragraph.

Stabilization

In connection with the offering, the underwriters may purchase and sell shares of Class A Shares in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of Class A Shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional Class A Shares for which the underwriters’ option described above may be exercised.

The underwriters may cover any covered short position by either exercising their option to purchase additional Class A Shares or purchasing Class A Shares in the open market. In determining the source of Class A Shares to cover the covered short position, the underwriters will consider, among other things, the price of Class A Shares available for purchase in the open market as compared to the price at which they may purchase additional Class A Shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional Class A Shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing Class A Shares in the open market. 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 Class A Shares in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of Class A Shares made by the underwriters in the open market prior to the closing of the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased Class A Shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the Company’s Class A Shares, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of the Class A Shares. As a result, the price of the Class A Shares may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on NYSE, in the over-the-counter market or otherwise.

Certain Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. The underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to the Company and to persons and entities with relationships with the Company, for which they received or will receive customary fees and expenses. For example, the underwriters or their affiliates are lenders under our credit facility.

In the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the Company (directly, as collateral securing other obligations

S-16

or otherwise) and/or persons and entities with relationships with the Company. The underwriters and 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 assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

Selling Restrictions

European Economic Area

In relation to each Member State of the European Economic Area (each a “Member State”), no Class A Shares have been offered or will be offered pursuant to the offering to the public in that Member State prior to the publication of a prospectus in relation to the Class A Shares which has been approved by the competent authority in that Member State or, where appropriate, approved in another Member State and notified to the competent authority in that Member State, all in accordance with the Prospectus Regulation, except that offers of Class A Shares may be made to the public in that Member State at any time under the following exemptions under the Prospectus Regulation:

provided that no such offer of Class A Shares shall require the Company or any representative to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation.

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

Prohibition of Sales to EEA Retail Investors

The Class A Shares are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area. 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 2016/97/EU (as amended), 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 2017/1129/EU (as amended or superseded, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the Class A Shares or otherwise making them available to retail investors in the European Economic Area has been prepared and therefore offering or selling the Class A Shares or otherwise making them available to any retail investor in the European Economic Area may be unlawful under the PRIIPs Regulation.

This prospectus supplement and the accompanying base prospectus have been prepared on the basis that any offer of the Class A Shares in any Member State of the European Economic Area will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of the Class A Shares. Neither this prospectus supplement nor the accompanying base prospectus is a prospectus for the purposes of the Prospectus Regulation.

provided that no such offer of the Class A Shares shall require the Company or any representative to publish a prospectus pursuant to Section 85 of the FSMA or supplement a prospectus pursuant to Article 23 of the UK Prospectus Regulation. For the purposes of this provision, the expression an “offer to the public” in relation to the Class A Shares in the United Kingdom means the communication in any form and by any means of sufficient information on the terms of the offer and any Class A Shares to be offered so as to enable an investor to decide to purchase or subscribe for any Class A Shares and the expression “UK Prospectus Regulation” means Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018.

In addition, in the United Kingdom, this document is being distributed only to, and is directed only at, and any offer subsequently made may only be directed at persons who are “qualified investors” (as defined in the Prospectus Regulation) (i) who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Order”) and/or (ii) who are high net worth companies (or persons to whom it may otherwise be lawfully communicated) falling within Article 49(2)(a) to (d) of the Order (all such persons together being referred to as “relevant persons”) or otherwise in circumstances which have not resulted and will not result in an offer to the public of the Class A Shares in the United Kingdom within the meaning of the Financial Services and Markets Act 2000.

Any person in the United Kingdom that is not a relevant person should not act or rely on the information included in this document or use it as basis for taking any action. In the United Kingdom, any investment or investment activity that this document relates to may be made or taken exclusively by relevant persons.

FORWARD-LOOKING STATEMENTS

This prospectus contains, and the applicable prospectus supplement and other documents incorporated by reference therein and herein may contain “forward-looking statements” within the meaning of U.S. federal securities laws. Words such as “anticipate,” “estimate,” “expect,” “forecast,” “guidance,” “could,” “may,” “should,” “would,” “believe,” “intend,” “project,” “plan,” “predict,” “will,” “target” and similar expressions identify forward-looking statements, which are not historical in nature. Our forward-looking statements may include, without limitation: our future financial and operational results; our business strategy; our industry; our expected revenues; our future profitability; our maintenance or expansion projects; our projected budget and capital expenditures and the impact of such expenditures on our performance; and future economic and market conditions in the oil and gas industry.

Forward-looking statements are based on our current understanding, assessments, estimates and projections of relevant factors and reasonable assumptions about the future. Forward-looking statements are subject to certain known and unknown risks and uncertainties that could cause actual results to differ materially from our historical experience and our current projections or expectations of future results expressed or implied by these forward-looking statements. The following important factors could cause actual results to differ materially from those in our forward-looking statements:

3

As and when made, we believe that our forward-looking statements are reasonable. However, given these risks and uncertainties, caution should be taken not to place undue reliance on any such forward-looking statements since such statements speak only as of the date when made and there can be no assurance that such forward-looking statements will occur and actual results may differ materially from those contained in any forward-looking statement we make. Except as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether because of new information, future events or otherwise.

HESS MIDSTREAM LP

Unless the context otherwise requires, references in this section to the “Company,” “we,” “our,” “us” or like terms, refer to Hess Midstream LP and its consolidated subsidiaries. The “Partnership” refers to Hess Midstream Operations LP (formerly known as Hess Midstream Partnership LP), a subsidiary of the Company. Our “general partner” refers to Hess Midstream GP LP. “Hess” refers collectively to Hess Corporation and its consolidated subsidiaries, other than us.

Overview

We are a fee-based, growth-oriented, limited partnership formed by Hess Infrastructure Partners GP LLC (“HIP GP LLC”) and our general partner in 2019 to own, operate, develop and acquire a diverse set of midstream assets and provide fee-based services to Hess and third-party customers. We are managed and controlled by Hess Midstream GP LLC, the general partner of our general partner that is owned 50/50 by Hess and GIP II Blue Holding, L.P. (“GIP”).

Our assets are primarily located in the Bakken and Three Forks shale plays in the Williston Basin area of North Dakota, which we collectively refer to as the “Bakken” in this prospectus. Our executive offices are located at 1501 McKinney Street, Houston, Texas 77010, and our telephone number at that address is (713) 496-4200.

Our Operating Segments

We conduct our business through three operating segments: (1) gathering, (2) processing and storage and (3) terminaling and export.

Gathering

Our gathering segment includes the following assets:

Processing and Storage

Our processing and storage segment includes the following assets:

5

Terminaling and Export

Our terminaling and export segment includes the following assets:

Commercial Agreements with Hess and Their Impact on Our Cash Flow Stability

We currently generate substantially all of our revenues under fee based commercial agreements with Hess (our “Commercial Agreements”), including third parties contracted with affiliates of Hess. We believe our Commercial Agreements provide us with stable and predictable cash flows and minimal direct exposure to commodity prices.

Our contract structure includes MVCs, inflation escalators and fee recalculation mechanisms, all of which are intended to provide us with cash flow stability and downside risk protection. Our MVCs, which apply on a three-year rolling basis and are currently fixed through 2025, provide minimum levels of cash flows, and the fee recalculation mechanism, which allows fees to be adjusted to target a return on capital deployed, supports cash flow stability.

6

RISK FACTORS

An investment in our securities involves risks. Limited partner interests are inherently different from capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in similar businesses. We urge you to carefully consider the risk factors included in our most recent Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, which are incorporated by reference into this prospectus and the applicable prospectus supplement, together with all of the other information included in this prospectus, the applicable prospectus supplement and the documents we incorporate by reference, in evaluating an investment in our securities. If any of the risks discussed in the foregoing documents were to materialize, our business, financial condition, results of operations and cash flows could be materially adversely affected and you could lose all or part of your investment. Please also read “Forward-Looking Statements.”

7

USE OF PROCEEDS

The actual application of proceeds to us from the sale of any particular offering of securities using this prospectus will be determined at the time of the offering and will be described in the applicable prospectus supplement relating to such offering. The precise amount and timing of the application of these proceeds will depend upon, among other factors, our funding requirements and the availability and cost of other funds.

DESCRIPTION OF OUR CLASS A SHARES AND CLASS B SHARES

Class A Shares

Class A Shares represent limited partner interests in us. The holders of Class A Shares are entitled to participate in our distributions and are entitled to exercise the rights and privileges available to limited partners under our partnership agreement. For a description of the relative rights and preferences of holders of Class A Shares in and to our distributions, please read this section and “Provisions of Our Partnership Agreement Relating to Cash Distributions.” For a description of the rights and privileges of limited partners under our partnership agreement, including voting rights, please read “Our Partnership Agreement.”

Our outstanding Class A Shares are listed on the NYSE under the symbol “HESM,” and any additional Class A Shares we issue will also be listed on the NYSE. As of February 24, 2023, there were 44,002,846 Class A Shares outstanding. On February 24, 2023, the last reported sales price of our Class A Shares on the NYSE was $28.11 per Class A Share.

Class B Shares

Class B Shares (“Class B Shares”) represent limited partner interests in us. The holders of Class B Shares are not entitled to participate in our distributions but are entitled to receive notice of, be included in any requisite quorum for, and participate in any and all approvals, votes or other actions of our partners on a pro rata basis as, and treating such persons for all such purposes as if they are, shareholders holding Class A Shares. For a description of the relative rights and preferences of holders of Class A Shares, please read this section and “Provisions of Our Partnership Agreement Relating to Cash Distributions.” For a description of the rights and privileges of limited partners under our partnership agreement, including voting rights, please read “Our Partnership Agreement.”

Redemption Right

Pursuant to our partnership agreement and the partnership agreement of the Partnership (the “Opco Partnership Agreement”), each holder of Class B units representing limited partner interest in the Partnership (“Class B Opco Units”) and Class B Shares is able to tender its Class B Opco Units and an equal number of its Class B Shares (one such Class B Opco Unit and one such Class B Share, together, a “Redeemed Security,” and collectively, the “Redeemed Securities”) for redemption to the Partnership. Each holder of Class B Opco Units and Class B Shares has the right to receive a number of Class A Shares equal to the number of Redeemed Securities. In the event of a redemption by the Partnership for Class A Shares, (i) we will contribute newly issued Class A Shares to the Partnership in order for the Partnership to redeem the applicable Class B Opco Units, (ii) we will cancel the applicable Class B Shares and (iii) the Partnership will issue the same number of Class A units representing limited partner interests in the Partnership (“Class A Opco Units”) to us. In addition, we have the right, but not the obligation, to directly purchase all or a portion of such Redeemed Securities for a number of Class A Shares equal to the number of Redeemed Securities we elect to purchase.

Jury Trial Waiver

Our partnership agreement provides that, to the extent permitted by law, holders of our shares waive the right to a jury trial of any claim they may have against us arising out of or relating to our shares or our partnership agreement, including any claim under the U.S. federal securities laws. If we opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable under the facts and circumstances of that case in accordance with applicable case law.

Transfer Agent and Registrar

Duties

Computershare Trust Company, N.A. (“Computershare”) serves as the transfer agent and registrar for the Class A Shares. We pay all fees charged by the transfer agent for transfers of Class A Shares except the following that must be paid by shareholders:

Unless our general partner determines otherwise in respect of some or all of any classes of our partner interests, our partner interests will be evidenced by book entry notation on our partnership register and not by physical certificates.

There will be no charge to our shareholders for disbursements of our cash distributions. We will indemnify Computershare, its agents and each of their respective stockholders, directors, officers and employees against all claims and losses that may arise out of acts performed or omitted for its activities in that capacity, except for any liability due to any gross negligence or intentional misconduct of the indemnified person or entity.

Resignation or Removal

The transfer agent may resign, by notice to us, or be removed by us. The resignation or removal of the transfer agent will become effective upon our appointment of a successor transfer agent and registrar and its acceptance of the appointment.

Transfer of Class A Shares

By transfer of Class A Shares in accordance with our partnership agreement, each transferee of Class A Shares will be admitted as a shareholder of the Company when such transfer and admission is reflected in the Company’s register and such transferee becomes the record holder of the limited partner interests so transferred. Additionally, each transferee of shares:

Class A Shares are securities and are transferable according to the laws governing transfers of securities. In addition to other rights acquired upon transfer, the transferor gives the transferee the right to become a substituted limited partner in the Company for the transferred shares.

The transfer agent and registrar for any Preferred Shares will be designated in the applicable prospectus supplement.

PROVISIONS OF OUR PARTNERSHIP AGREEMENT RELATING TO CASH DISTRIBUTIONS

Set forth below is a summary of the significant provisions of our partnership agreement that relate to cash distributions.

Distributions of Available Cash

General

Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash to shareholders of record on the applicable record date. Except for splits and combinations as contemplated by our partnership agreement, no distribution shall be made under any circumstances in respect of any Class B Shares or our general partner interest.

Definition of Available Cash

Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter:

The purpose and effect of the last bullet point above is to allow our general partner, if it so decides, to use cash from working capital borrowings made after the end of the quarter but on or before the date of determination of available cash for that quarter to pay distributions to shareholders. Under our partnership agreement, working capital borrowings are generally borrowings that are made under a credit facility, commercial paper facility or similar financing arrangement, and in all cases are used solely for working capital purposes or to pay distributions to partners and with the intent of the borrower to repay such borrowings within twelve months with funds other than from additional working capital borrowings.

Intent to Distribute the Minimum Quarterly Distribution

Under our current cash distribution policy, we intend to make a minimum quarterly distribution to the holders of our Class A Shares of $0.30 per share, or $1.20 per share on an annualized basis, to the extent we have sufficient available cash after the establishment of cash reserves and the payment of costs and expenses, including reimbursements of expenses to our general partner. However, there is no guarantee that we will pay the minimum quarterly distribution on our Class A Shares in any quarter. The amount of distributions paid under our cash distribution policy and the decision to make any distribution will be determined by our general partner, taking into consideration the terms of our partnership agreement.

12

General Partner Interest

Our general partner owns a non-economic general partner interest in us and, as of February 24, 2023, 898,000 Class A Shares and 195,847,606 Class B Shares. Our general partner, in its capacity as a Class A shareholder, is entitled to share in cash distributions on our Class A Shares, but is not otherwise entitled to receive cash distributions with respect to its general partner interest in us or its Class B Shares. However, our general partner may in the future own other equity interests in us and may be entitled to receive distributions on any such interests.

Distributions to Class A Shares

As of February 24, 2023, we had 44,002,846 Class A Shares outstanding. Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash to shareholders of record on the applicable record date.

Distributions to Class B Shares

As of February 24, 2023, we had 195,847,606 Class B Shares outstanding, all of which were held by our general partner. Except for splits and combinations as contemplated by our partnership agreement, no distribution shall be made under any circumstances in respect of any Class B Shares.

Adjustment of the Minimum Quarterly Distribution

If we combine our Class A Shares and Class B Shares (collectively, the “Shares”) or other interests in us (“Company Interests”) into fewer Shares or Company Interests (commonly referred to as a “reverse split”) or subdivide our Shares or Company Interests into a greater number of Shares or Company Interests (commonly referred to as a “split”), we will proportionately adjust the minimum quarterly distribution.

For example, if a two-for-one split of Class A Shares should occur, the minimum quarterly distribution would be reduced to 50% of its initial level. We will not make any adjustment by reason of the issuance of additional Shares or Company Interests for cash or property (including additional Class A Shares issued under any compensation or benefit plans).

Distributions of Cash Upon Liquidation

General

If we dissolve in accordance with our partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to all record holders of Class A Shares, pro rata, and such distribution will be made by the end of such taxable period (or, if later, within 90 days after said date of such occurrence).

13

OUR PARTNERSHIP AGREEMENT

The following is a summary of the material provisions of our partnership agreement. We will provide prospective investors with a copy of our partnership agreement upon request at no charge. We summarize the following provisions of our partnership agreement elsewhere in this prospectus:

Organization and Duration

The Company was organized on September 27, 2019, and will have a perpetual existence unless terminated pursuant to the terms of our partnership agreement.

Purpose

Our purpose under our partnership agreement is limited to any business activity that is approved by our general partner and that lawfully may be conducted by a limited partnership organized under Delaware law. We are expressly permitted to make capital contributions or loans to our subsidiaries and their respective affiliates that we control or its subsidiaries.

Although our general partner has the ability to cause us and our subsidiaries to engage in activities other than the business of directly or indirectly owning, operating, developing and acquiring midstream logistics assets, our general partner has no current plans to do so and may decline to do so free of any duty or obligation whatsoever to us or our shareholders, including any duty to act in our best interests or those of our shareholders, other than the implied contractual covenant of good faith and fair dealing. Our general partner is authorized in general to perform all acts it determines to be necessary or appropriate to carry out our purposes and to conduct our business.

Cash Distributions

Our partnership agreement specifies the manner in which we will make cash distributions to holders of our Class A Shares and other Company Interests. For a description of these cash distribution provisions, please read “Provisions of Our Partnership Agreement Relating to Cash Distributions.”

Capital Contributions

Shareholders are not obligated to make additional capital contributions, except as described below under “—Limited Liability.”

Voting Rights

Our general partner is responsible for managing us, and our shareholders have the right to vote on matters only if referred to them by our general partner or as otherwise expressly provided in our partnership agreement. The following is a summary of the shareholder vote required for the matters specified below. Matters that require the approval of a “share majority” require the approval of at least a majority of the issued and outstanding Class A Shares and Class B Shares, voting together as a single class. In voting their shares, our general partner and its affiliates will have no duty or obligation whatsoever to the Company or the limited partners, including any duty to act in the best interests of the Company or the limited partners, other than the implied contractual covenant of good faith and fair dealing.

14

Voting Rights of the Class B Shares

Each holder of a Class B Share will be entitled to receive notice of, be included in any requisite quorum for, and participate in any and all approvals, votes or other actions of the partners of the Company on a pro rata basis as, and treating such persons for all such purposes as if they are shareholders holding Class A Shares. The affirmative vote of the holders of a majority of the voting power of all Class B Shares voting separately as a class will be required to alter, amend or repeal such voting rights of Class B Shares or to adopt any provision of the Opco Partnership Agreement inconsistent with such rights.

15

Limited Liability

Assuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Revised Uniform Limited Partnership Act (the “Delaware Act”) and that it otherwise acts in conformity with the provisions of our partnership agreement, its liability under the Delaware Act will be limited, subject to possible exceptions, to the amount of capital it is obligated to contribute to us for its Class A Shares or Class B Shares plus its share of any undistributed profits and assets. If it were determined, however, that the right, or exercise of the right of, by the limited partners as a group:

constituted “participation in the control” of our business for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware, to the same extent as our general partner. This liability would extend to persons who transact business with us who reasonably believe that a limited partner is a general partner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. While this does not mean that a limited partner could not seek legal recourse, we know of no precedent for this type of a claim in Delaware case law.

Under the Delaware Act, a limited partnership may not make a distribution to a partner if, after the distribution, all liabilities of the limited partnership, other than liabilities to partners on account of their limited partner interests and liabilities for which the recourse of creditors is limited to specific property of the limited partnership, would exceed the fair value of the assets of the limited partnership, except that the fair value of property that is subject to a liability for which the recourse of creditors is limited is included in the assets of the limited partnership only to the extent that the fair value of that property exceeds that liability. For the purpose of determining the fair value of the assets of a limited partnership, the Delaware Act provides that the fair value of property subject to liability for which recourse of creditors is limited shall be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act shall be liable to the limited partnership for the amount of the distribution for three years. Under the Delaware Act, a substituted limited partner of a limited partnership is liable for the obligations of its assignor to make contributions to the limited partnership, except that such person is not obligated for liabilities unknown to it at the time it became a limited partner and that could not be ascertained from the partnership agreement.

Our subsidiaries conduct business in several states and we may have subsidiaries that conduct business in other states in the future. Maintenance of our limited liability as a member or limited partner of our subsidiaries, may require compliance with legal requirements in the jurisdictions in which our subsidiaries conduct business, including qualifying our subsidiaries to do business there.

Limitations on the liability of members or limited partners for the obligations of a limited liability company or limited partnership have not been clearly established in many jurisdictions. If, by virtue of tour ownership interests in our operating subsidiaries or otherwise, it were determined that we were conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by the limited partners as a group to remove or replace our general partner, to approve some amendments to the partnership agreement, or to take other action under the partnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then our limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

16

Issuance of Additional Company Interests

We are authorized to issue an unlimited number of additional Company Interests for the consideration and on the terms and conditions determined by our general partner without the approval of the holders of our shares; provided, however, that we may not issue any Class A Shares unless we contribute the net cash proceeds or other consideration received from the issuance of such Class A Shares to the Partnership in exchange for an equivalent number of Class A Opco Units.

It is possible that we will fund acquisitions through the issuance of additional Class A Shares, Class B Shares or other Company Interests. Holders of any additional shares (other than Class B Shares) issued by us will be entitled to share equally with then-existing holders of Class A Shares in our distributions of available cash. In addition, the issuance of additional shares or other Company Interests may dilute the value of the interests of then-existing holders of Class A Shares in the Company’s net assets.

In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional Company Interests that, as determined by our general partner, may have special voting rights to which the Class A Shares or Class B Shares are not entitled. In addition, our partnership agreement does not prohibit the issuance by our subsidiaries of equity interests that may effectively rank senior to the Class A Shares or Class B Shares.

If at any time, our general partner, Hess Investments North Dakota LLC, GIP or any other record holder of one or more Class B Shares does not hold (including its affiliates) an equal number of Class B Shares and Class B Opco Units, we will issue additional Class B Shares to such holder or cancel Class B Shares held by such holder, as applicable, so that the number of Class B Shares directly or indirectly held by such holder and its affiliates is equal to the number of Class B Opco Units directly or indirectly held by such holder and its affiliates.

Our general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase shares or other Company Interests whenever, and on the same terms that, we issue those interests to persons other than our general partner and its affiliates, to the extent necessary to maintain the percentage interest of our general partner and its affiliates, including such interest represented by the Company Interests, that existed immediately prior to each issuance. The other holders of shares will not have preemptive rights to acquire additional Class A Shares or Class B Shares or other Company Interests.

In addition, pursuant to the Opco Partnership Agreement, each holder of Class B Opco Units and Class B Shares will be able to tender its Class B Opco Units and Class B Shares for redemption to the Partnership. In exchange, such holder of Class B Opco Units and Class B Shares will be granted the right to receive a number of the Class A Shares equal to the number of Class B Opco Units included in the Redeemed Securities. See “Description of Class A Shares and Class B Shares—Class B Shares—Redemption Right.”

Amendment of Our Partnership Agreement

General

Amendments to our partnership agreement may be proposed only by our general partner. However, our general partner will have no duty or obligation to propose any amendment and may decline to do so free of any duty or obligation whatsoever to the Company or the Company’s limited partners, including any duty to act in the best interests of the Company or the limited partners, other than the implied contractual covenant of good faith and fair dealing. In order to adopt a proposed amendment, other than the amendments discussed below, our general partner is required to seek written approval of the holders of the number of the Company shares required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment. Except as described below, an amendment must be approved by a share majority.

17

Prohibited amendments

No amendment may be made that would, among other actions:

The provisions of our partnership agreement preventing the amendments having the effects described in any of the clauses above can be amended upon the approval of the holders of at least 90% of our outstanding shares, voting together as a single class (including shares owned by our general partner and its affiliates). As of February 24, 2023, our general partner and its affiliates owned approximately 82% of our total outstanding shares on an aggregate basis.

No shareholder approval

Our general partner may generally make amendments to the partnership agreement without the approval of any limited partner to reflect:

18

In addition, our general partner may make amendments to our partnership agreement without the approval of any limited partner if our general partner determines that those amendments:

Opinion of counsel and shareholder approval

For amendments of the type not requiring shareholder approval, our general partner will not be required to obtain an opinion of counsel to the effect that an amendment will not affect the limited liability of any limited partner under Delaware law. No other amendments to our partnership agreement will become effective without the approval of holders of at least 90% of the outstanding shares voting as a single class unless we first obtain such an opinion of counsel.

In addition to the above restrictions, any amendment that would have a material adverse effect on the rights or preferences of any type or class of Company Interests in relation to other classes of Company Interests will require the approval of at least a majority of the type or class of Company Interests so affected. Any amendment that would reduce the percentage of shares required to take any action, other than to remove our general partner or call a meeting of shareholders, must be approved by the affirmative vote of limited partners whose aggregate outstanding shares constitute not less than the percentage sought to be reduced. Any amendment that would increase the percentage of shares required to remove our general partner must be approved by the affirmative vote of limited partners whose aggregate outstanding shares constitute not less than 90% of outstanding shares. Any amendment that would increase the percentage of shares required to call a meeting of shareholders must be approved by the affirmative vote of limited partners whose aggregate outstanding shares constitute at least a majority of the outstanding shares.

Merger, Consolidation, Conversion, Sale or Other Disposition of Assets

A merger, consolidation or conversion of us requires the prior consent of our general partner. However, our general partner will have no duty or obligation to consent to any merger, consolidation or conversion and may decline to do so free of any duty or obligation whatsoever to us or our limited partners, including any duty to act in the best interest of us or our limited partners, other than the implied contractual covenant of good faith and fair dealing.

In addition, our partnership agreement generally prohibits our general partner, without the prior approval of the holders of a share majority, from causing us to, among other things, sell, exchange or otherwise dispose of all or substantially all of our assets in a single transaction or a series of related transactions. Our general partner may, however, mortgage, pledge, hypothecate, or grant a security interest in all or substantially all of our assets without that approval. Our general partner may also sell any or all of our assets under a foreclosure or other realization upon those encumbrances without that approval. Finally, our general partner may consummate any

19

merger with another limited liability entity without the prior approval of the shareholders if we are is the surviving entity in the transaction, our general partner has received an opinion of counsel regarding limited liability and tax matters, the transaction would not result in an amendment to the partnership agreement requiring shareholder approval, each of our shares will be an identical share of the Company following the transaction and the Company Interests to be issued by us in such merger do not exceed 20% of our outstanding Company Interests immediately prior to the transaction.

Termination and Dissolution

We will continue as a limited partnership until dissolved and terminated under our partnership agreement. We will dissolve upon:

Upon a dissolution under the first clause above, the holders of a share majority may also elect, within specific time limitations, to continue our business on the same terms and conditions described in our partnership agreement by appointing as a successor general partner an entity approved by the holders of shares representing a share majority, subject to our receipt of an opinion of counsel to the effect that the action would not result in the loss of limited liability of any limited partner.

Liquidation and Distribution of Proceeds

Upon our dissolution, unless we are continued as a new limited partnership, the liquidator authorized to wind up our affairs will, acting with all of the powers of our general partner that are necessary or appropriate to, liquidate our assets and apply the proceeds of the liquidation pursuant to our partnership agreement. The liquidator may defer liquidation or distribution of our assets for a reasonable period of time or distribute assets to partners in kind if it determines that a sale would be impractical or would cause undue loss to our partners.

Withdrawal or Removal of Our General Partner

Except as described below, our general partner has agreed not to withdraw voluntarily as our general partner prior to June 30, 2027, without obtaining the approval of the holders of at least a majority of the outstanding shares, excluding shares held by our general partner and its affiliates, and furnishing an opinion of counsel regarding limited liability and tax matters. On or after June 30, 2027, our general partner may withdraw as general partner without first obtaining approval of any shareholder by giving 90 days’ written notice, and that withdrawal will not constitute a violation of our partnership agreement. Notwithstanding the information above, our general partner may withdraw without shareholder approval upon 90 days’ written notice to the limited partners if at least 50% of the outstanding shares are held or controlled by one person and its affiliates other than our general partner and its affiliates. In addition, our partnership agreement permits our general partner in some instances to sell or otherwise transfer all of its general partner interest in us without the approval of the holders of our shares. See “—Transfer of General Partner Interest.”

Upon voluntary withdrawal of our general partner by giving notice to the other partners, the holders of a share majority may select a successor to that withdrawing general partner. If a successor is not elected, or is

20

elected but an opinion of counsel regarding limited liability cannot be obtained, the Company will be dissolved, wound up and liquidated, unless within a specified period after that withdrawal, the holders of a share majority agree to continue our business by appointing a successor general partner. See “—Termination and Dissolution.”

Our general partner may not be removed unless that removal is for cause and is approved by the vote of the holders of not less than 66 2/3% of our outstanding shares, voting together as a single class, including shares held by our general partner and its affiliates, and we receive an opinion of counsel regarding limited liability. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding shares, voting together as a single class. The ownership of more than 33 1/3% of the outstanding shares by our general partner and its affiliates would give them the practical ability to prevent our general partner’s removal. At the closing of the Restructuring, our general partner and its affiliates held 94% of our total outstanding shares on an aggregate basis.

In the event of removal of our general partner under circumstances where cause exists or withdrawal of our general partner where that withdrawal violates our partnership agreement, a successor general partner will have the option to purchase our general partner interest of the departing general partner for a cash payment equal to the fair market value of those interests. Under all other circumstances where our general partner withdraws or is removed by the limited partners, the departing general partner will have the option to require the successor general partner to purchase our general partner interest of the departing general partner for fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner will become a limited partner and its general partner interest will automatically convert into shares pursuant to a valuation of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, all employee-related liabilities, including severance liabilities, incurred for the termination of any employees employed by the departing general partner or its affiliates for the Company’s benefit.

Transfer of General Partner Interest

Except for transfer by our general partner of all, but not less than all, of its general partner interest to (1) an affiliate of our general partner (other than an individual), or (2) another entity as part of the merger or consolidation of our general partner with or into such entity or the transfer by our general partner of all or substantially all of its assets to such entity, our general partner may not transfer all or any part of its general partner interest to another person prior to June 30, 2027 without the approval of the holders of at least a majority of the outstanding shares, excluding shares held by our general partner and its affiliates, voting as a single class. As a condition of this transfer, the transferee must assume, among other things, the rights and duties of our general partner, agree to be bound by the provisions of our partnership agreement, and furnish an opinion of counsel regarding limited liability.

Transfer of Ownership Interests in Our General Partner

At any time, HIP GP LLC and its affiliates may sell or transfer all or part of their interest in our general partner to an affiliate or third party without the approval of our shareholders.

21

Transfer of Class B Shares

No holder of Class B Shares may transfer any of its Class B Shares to any person other than the Company without the consent of our general partner, except that such holder may transfer one or more Class B Shares to any person so long as an equal number of Class B Opco Units are simultaneously transferred by such holder to such person pursuant to the Opco Partnership Agreement. However, our general partner and its affiliates may transfer any or all of its Class B Shares to any person without the approval of any limited partner of the Company or any other person.

Change of Management Provisions

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove Hess Midstream GP LP as our general partner or otherwise change the Company’s management. If any person or group other than the general partner and its affiliates acquires beneficial ownership of 20% or more of any class of shares, that person or group loses voting rights on all of its shares. This loss of voting rights does not apply to any person or group that acquires the shares from our general partner or its affiliates and any transferees of that person or group who are notified by the general partner that they will not lose their voting rights or to any person or group who acquires the shares with the prior approval of our board of directors. See “—Withdrawal or Removal of Our General Partner.”

Limited Call Right

If at any time our general partner and its affiliates own more than a certain designated percentage (as described below) of then-issued and outstanding Company Interests of any class (for purposes of which Class A Shares and Class B Shares will be considered Company Interests of a single class), our general partner will have the right, which it may assign in whole or in part to any of its affiliates or to the Company, to acquire all, but not less than all, of the limited partner interests of such class held by unaffiliated persons as of a record date to be selected by our general partner, on at least 10, but not more than 60, days’ written notice.

The designated percentage for all classes of Company Interests other than Class A Shares will be 80%, and the designated percentage for Class A Shares as of the Closing Date will be equal to 97%. If the percentage of the Class A Shares held by our general partner and its affiliates (considering the Class A Shares and together with the Class B Shares as a single class) (“GP Percentage”) is:

The purchase price in the event of this purchase is the greater of:

22

As a result of our general partner’s right to purchase outstanding Company Interests, a holder of Company Interests may have his Company Interests purchased at a price that may be lower than market prices at various times prior to such purchase or lower than a shareholder may anticipate the market price to be in the future. The tax consequences to a shareholder of the exercise of this call right are the same as a sale by that shareholder of his or her Class A Shares in the market.

Meetings; Voting

Except as described below regarding a person or group owning 20% or more of any class of shares then outstanding, holders of shares on the record date will be entitled to notice of, and to vote at, meetings of the Company’s limited partners and to act upon matters for which approvals may be solicited.

Our general partner does not anticipate that any meeting of shareholders will be called in the foreseeable future. Any action that is required or permitted to be taken by shareholders may be taken either at a meeting of the shareholders or, if authorized by the general partner, without a meeting if consents in writing describing the action so taken are signed by holders of the number of shares that would be necessary to authorize or take that action at a meeting where all limited partners were present and voted. Meetings of the shareholders may be called by the general partner or by shareholders owning at least 20% of the outstanding shares of the class for which a meeting is proposed. shareholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding shares of the class or classes for which a meeting has been called, represented in person or by proxy, will constitute a quorum unless any action by the shareholders requires approval by holders of a greater percentage of the shares, in which case the quorum will be the greater percentage. The general partner interest does not entitle the general partner to any vote other than its rights as general partner under the partnership agreement, will not be entitled to vote on any action required or permitted to be taken by the shareholders and will not count toward or be considered outstanding when calculating required votes, determining the presence of a quorum, or for similar purposes.

Each record holder of a share has a vote according to its percentage interest in the Company, although additional limited partner interests having special voting rights could be issued. See “—Issuance of Additional Company Interests.” However, if at any time any person or group, other than the general partner and its affiliates, a direct transferee of the general partner and its affiliates or a transferee of such direct transferee who is notified by the general partner that it will not lose its voting rights, acquires, in the aggregate, beneficial ownership of 20% or more of any class of shares then outstanding, that person or group will lose voting rights on all of its shares and the shares may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of shareholders, calculating required votes, determining the presence of a quorum, or for other similar purposes. Shares held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and its nominee provides otherwise. Class B Shares will vote together with Class B Shares as a single class. Any notice, demand, request, report or proxy material required or permitted to be given or made to record holders of shares under the partnership agreement will be delivered to the record holder by the Company or by the transfer agent.

Status as Limited Partner

By transfer of shares in accordance with our partnership agreement, each transferee of shares shall be admitted as a limited partner with respect to the shares transferred when such transfer and admission is reflected in our register. Except as described under “—Limited Liability,” the shares will be fully paid, and shareholders will not be required to make additional contributions.

23

Indemnification

Under our partnership agreement, in most circumstances, we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages or similar events:

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, our general partner will not be personally liable for, or have any obligation to contribute or lend funds or assets to us to enable us to effectuate, indemnification. We will purchase insurance against liabilities asserted against and expenses incurred by persons for our activities, regardless of whether we would have the power to indemnify the person against such liabilities under our partnership agreement.

Reimbursement of Expenses

Our partnership agreement requires us to reimburse our general partner for all direct and indirect expenses it incurs or payments it makes on our behalf and all other expenses allocable to us or otherwise incurred by the general partner in connection with operating our business. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by its affiliates. The general partner is entitled to determine in good faith the expenses that are allocable to us. The expenses for which we are required to reimburse our general partner are not subject to any caps or other limits.

Books and Reports

Our general partner is required to keep appropriate books of our business at our principal offices. The books are maintained for financial reporting purposes on an accrual basis. For fiscal and tax reporting purposes, our fiscal year is the calendar year.

We will mail or make available to record holders of Class A Shares, within 105 days after the close of each fiscal year, an annual report containing audited financial statements and a report on those financial statements by our independent public accountants. Except for our fourth quarter, we will also mail or make available summary financial information within 50 days after the close of each quarter.

Right to Inspect Our Books and Records

Our partnership agreement provides that a limited partner can, for a purpose reasonably related to its interest as a limited partner, upon reasonable written demand stating the purpose of such demand and at its own expense, have furnished to him:

24

Our general partner may, and intends to, keep confidential from the limited partners trade secrets or other information the disclosure of which our general partner determines is not in our best interests or that we are required by law or by agreements with third parties to keep confidential. Our partnership agreement limits the right to information that a limited partner would otherwise have under Delaware law.

Registration Rights

Under our partnership agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any Class A Shares or Company Interests proposed to be sold by our general partner or any of its affiliates (other than individuals) or their assignees if an exemption from the registration requirements is not otherwise available. We are obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

Exclusive Forum

Our partnership agreement provides that our shareholders shall waive the right to a jury trial of, and that the Court of Chancery of the State of Delaware shall be the exclusive forum for, any claims, suits, actions or proceedings (1) arising out of or relating in any way to our partnership agreement (including any claims, suits or actions to interpret, apply or enforce the provisions of our partnership agreement or the duties, obligations or liabilities among the Company’s partners, or obligations or liabilities of the Company’s partners to the Company, or the rights or powers of, or restrictions on, the Company’s partners or the Company), (2) brought in a derivative manner on the Company’s behalf, (3) asserting a claim of breach of a duty owed by any of the Company’s, or the general partner’s, directors, officers, or other employees, or owed by our general partner, to the Company or the Company’s partners, (4) asserting a claim against the Company arising pursuant to any provision of the Delaware Act or (5) asserting a claim against the Company governed by the internal affairs doctrine. However, the exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. Although the Company believes this provision benefits the Company by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against the Company’s directors and officers. The enforceability of similar choice of forum provisions in other companies’ certificates of incorporation or similar governing documents have been challenged in legal proceedings, and it is possible that, in connection with any action, a court could find the choice of forum provisions contained in our partnership agreement to be inapplicable or unenforceable in such action.

By purchasing a Class A Share or Class B Share, a limited partner is irrevocably consenting to these limitations and provisions regarding claims, suits, actions or proceedings and submitting to the exclusive jurisdiction of the Court of Chancery of the State of Delaware (or such other court) in connection with any such claims, suits, actions or proceedings.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our Class A Shares, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our Class A Shares. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our Class A Shares.

This discussion is limited to Non-U.S. Holders that hold our Class A Shares as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our Class A Shares, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our Class A Shares and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

26

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A SHARES ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Corporate Status

Although we are a Delaware limited partnership, we have elected to be treated as a corporation for U.S. federal income tax purposes. As a result, we are subject to tax as a corporation, and distributions on our Class A Shares are treated as distributions on corporate stock for U.S. federal income tax purposes. In addition, no Schedule K-1s will be issued with respect to our Class A Shares; instead holders of Class A Shares will receive a Form 1099 from us with respect to distributions received on our Class A Shares.

Consequences to Non-U.S. Holders

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our Class A Shares that is neither a “U.S. person” nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

Distributions

Distributions of cash or property on our Class A Shares will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its Class A Shares, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “—Sale or Other Taxable Disposition.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our Class A Shares will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S.

27

Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Class A Shares unless:

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain realized by a Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we are and will continue to be a USRPHC. The determination of whether we are a USRPHC depends on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets. If we are or become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our Class A Shares will not be subject to U.S. federal income tax if our Class A Shares are “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Class A Shares throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder’s holding period.

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our Class A Shares will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a U.S. person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our Class A Shares paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Class A Shares within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a U.S. person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A Shares conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, our Class A Shares paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A Shares. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of shares on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A Shares.

TAX CONSEQUENCES OF OWNERSHIP OF PREFERRED SHARES

A description of the material federal income tax consequences of the acquisition, ownership and disposition of Preferred Shares will be set forth in a prospectus supplement relating to the offering of Preferred Shares.

INVESTMENT IN HESS MIDSTREAM LP BY EMPLOYEE BENEFIT PLANS

An investment in our Class A Shares and/or preferred securities by an employee benefit plan is subject to certain additional considerations because the investments of these plans are subject to the fiduciary responsibility and prohibited transaction provisions of the Employee Retirement Income Security Act of 1974, as amended, or ERISA, and the prohibited transaction restrictions imposed by Section 4975 of the Code or provisions under any federal, state, local, non-U.S. or other laws, rules or regulations that are similar to such provisions of the Code or ERISA, which we refer to collectively as “Similar Laws.” As used herein, the term “employee benefit plan” includes, but is not limited to, qualified pension, profit-sharing and stock bonus plans, certain Keogh plans, certain simplified employee pension plans and tax deferred annuities or individual retirement accounts or other arrangements established or maintained by an employer or employee organization, and entities whose underlying assets are considered to include “plan assets” of such plans, accounts and arrangements.

This summary is based on the provisions of ERISA and the Code (and related regulations and administrative and judicial interpretations) as of the date of this prospectus. This summary does not purport to be complete and future legislation, court decisions, administrative regulations, rulings or administrative pronouncements could significantly modify the requirements summarized below. Any of these changes may be retroactive and, therefore, may apply to transactions entered into prior to the date of their enactment or release.

General Fiduciary Matters

ERISA and the Code impose certain duties on persons who are fiduciaries of an employee benefit plan that is subject to Title I of ERISA or Section 4975 of the Code, which we refer to as an “ERISA Plan,” and prohibit certain transactions involving the assets of an ERISA Plan and its fiduciaries or other interested parties. Under ERISA and the Code, any person who exercises any discretionary authority or control over the administration of such an ERISA Plan or the management or disposition of the assets of an ERISA Plan, or who renders investment advice for a fee or other compensation to an ERISA Plan, is generally considered to be a fiduciary of the ERISA Plan. In considering an investment in our Class A Shares or preferred securities with any portion of the assets of an employee benefit plan, a fiduciary of the employee benefit plan should consider, among other things, whether the investment is in accordance with the documents and instruments governing the employee benefit plan and the applicable provisions of ERISA, the Code or any applicable Similar Law relating to the fiduciary’s duties to the employee benefit plan, including, without limitation:

(a) whether the investment is prudent under Section 404(a)(1)(B) of ERISA and any other applicable Similar Laws;

(b) whether, in making the investment, the employee benefit plan will satisfy the diversification requirements of Section 404(a)(1)(C) of ERISA and any other applicable Similar Laws;

(c) whether making the investment will comply with the delegation of control and prohibited transaction provisions under Section 406 of ERISA, Section 4975 of the Internal Revenue Code and any other applicable Similar Laws (please read the discussion under “—Prohibited Transaction Issues” below);

(d) whether in making the investment, the employee benefit plan will be considered to hold, as plan assets, (1) only the investment in our Class A Shares or (2) an undivided interest in our underlying assets (please read the discussion under “—Plan Asset Issues” below); and

30

(e) whether the investment will result in recognition of unrelated business taxable income by the employee benefit plan and, if so, the potential after-tax investment return. Please read “Material U.S. Income Tax Considerations.”

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit employee benefit plans (and certain IRAs that are not considered part of an employee benefit plan) from engaging in certain transactions involving “plan assets” with parties that are “parties in interest” under ERISA or “disqualified persons” under the Code with respect to the employee benefit plan or IRA, unless an exemption is applicable. A party in interest or disqualified person who engages in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. In addition, the fiduciary of the ERISA Plan that engaged in such a non-exempt prohibited transaction may be subject to excise taxes, penalties and liabilities under ERISA and the Code.

The acquisition and/or holding of the preferred securities by an ERISA Plan with respect to which we or the initial purchasers are considered a party in interest or a disqualified person, may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the preferred securities are acquired and held in accordance with an applicable statutory, class or individual prohibited transaction exemption. In this regard, the U.S. Department of Labor has issued prohibited transaction class exemptions, or PTCEs, that may apply to the acquisition, holding and, if applicable, conversion of the preferred securities. These class exemptions include, without limitation, PTCE 84-14 respecting transactions determined by independent qualified professional asset managers, PTCE 90-1 respecting insurance company pooled separate accounts, PTCE 91-38 respecting bank collective investment funds, PTCE 95-60 respecting life insurance company general accounts and PTCE 96-23 respecting transactions determined by in-house asset managers. There can be no assurance that all of the conditions of any such exemptions will be satisfied.

Because of the foregoing, our Class A Shares and/or the preferred securities may not be purchased or held (or converted to equity securities, in the case of any convertible preferred) by any person investing “plan assets” of any employee benefit plan, unless such purchase and holding (or conversion, if any) will not constitute a non-exempt prohibited transaction under ERISA or the Code or similar violation of any applicable Similar Laws.

Plan Asset Issues

In connection with an investment in the Class A Shares or preferred securities with any portion of the assets of an employee benefit plan, in addition to considering whether the purchase of our Class A Shares and/or preferred securities is a prohibited transaction, a fiduciary of an employee benefit plan should consider whether the plan will, by investing in our Class A Shares and/or preferred securities, be deemed to own an undivided interest in our assets, with the result that our general partner also would be a fiduciary of the plan and our operations would be subject to the regulatory restrictions of ERISA, including its prohibited transaction rules, as well as the prohibited transaction rules of the Code and any other applicable Similar Laws. In addition, if our assets are deemed to be “plan assets” under ERISA, this would result, among other things, in (a) the application of the prudence and other fiduciary responsibility standards of ERISA to investments made by us, and (b) the possibility that certain transaction in which we seek to engage could constitute “prohibited transaction” under the Code, ERISA and any other applicable Similar Laws.

The Department of Labor regulations, as modified by Section 3(42) of ERISA, provide guidance with respect to whether, in certain circumstances, the assets of an entity in which employee benefit plans acquire equity interests would be deemed “plan assets.” Under these regulations, an entity’s underlying assets generally would not be considered to be “plan assets” if, among other things:

(a) the equity interests acquired by the employee benefit plan are “publicly offered securities”—i.e., the equity interests are part of a class of securities that are widely held by 100 or more investors independent of the

31

issuer and each other, “freely transferable” (as defined in the applicable Department of Labor regulations) and either part of a class of securities registered pursuant to certain provisions of the federal securities laws or sold to the plan as part of a public offering under certain conditions;

(b) the entity is an “operating company”—i.e., it is primarily engaged in the production or sale of a product or service other than the investment of capital either directly or through a majority-owned subsidiary or subsidiaries, or it qualifies as a “venture capital operating company” or a “real estate operating company”; or

(c) there is no “significant” investment by benefit plan investors (as defined in Section 3(42) of ERISA), which is defined to mean that, immediately after the most recent acquisition of an equity interest in any entity by an employee benefit plan, less than 25% of the total value of each class of equity interest, (disregarding certain interests held by our general partner, its affiliates and certain other persons who have discretionary authority or control with respect to the assets of the entity or provide investment advice for a fee with respect to such assets) is held by the employee benefit plans that are subject to part 4 of Title I of ERISA (which excludes governmental plans and non-electing church plans) and/or Section 4975 of the Code, IRAs and certain other employee benefit plans not subject to ERISA (such as electing church plans).

With respect to an investment in our Class A Shares, we believe that our assets should not be considered “plan assets” under these regulations because it is expected that the investment will satisfy the requirements in (a) above and may also satisfy the requirements in (b) and/or (c) above (although there is little applicable Department of Labor guidance with respect to whether we may qualify as an “operating company” as required for compliance with (b), and we do not monitor the level of investment by benefit plan investors as required for compliance with (c)).

The foregoing discussion of issues arising for employee benefit plan investments under ERISA, the Code and applicable Similar Laws is general in nature and is not intended to be all inclusive, nor should it be construed as legal advice. Plan fiduciaries and other persons contemplating a purchase of our Class A Shares and/or the preferred securities should consult with their own counsel regarding the potential applicability of and consequences of such purchase under ERISA, the Code and other Similar Laws in light of the complexity of these rules and the serious penalties, excise taxes and liabilities imposed on persons who engage in non-exempt prohibited transactions or other violations. The sale of any Class A Shares and/or preferred securities by or to any employee benefit plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by such employee benefit plans generally or any particular employee benefit plan, or that such an investment is appropriate for such employee benefit plans generally or any particular employee benefit plan.

Representation

By purchase or acceptance of the Class A Shares and/or the preferred securities, each purchaser and subsequent transferee of the Class A Shares and/or the preferred securities will be deemed to have represented and warranted that either (i) no portion of the assets used by such purchaser or transferee to acquire and hold the Class A Shares and/or the preferred securities constitutes assets of any employee benefit plan or (ii) the purchase and holding (and any conversion, if applicable) of the Class A Shares and/or the preferred securities by such purchaser or transferee will not constitute a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or similar violation under any applicable Similar Laws.
