The principal accounting policies applied in the preparation of the consolidated financial statements are set out below. These policies have been consistently applied for all periods presented, unless otherwise stated. The financial statements were authorized for issue by the Company´s board of directors on Nov. 4, 2021.

The consolidated financial statements of the Group are presented in U.S. dollars. Unless otherwise indicated, all amounts are shown in millions of U.S. dollars rounded to one decimal place in accordance with standard commercial practice, which may result in rounding differences and percentage figures presented may not exactly reflect the absolute figures they relate to. Values of 0.0 indicate that the rounded value is equivalent to zero while an em dash (“—“) is used when no value is available.

The preparation of the consolidated financial statements in accordance with IFRS (as issued by the IASB) requires management to exercise judgement and to make estimates and assumptions that affect the application of policies, reported amounts of revenues, expenses, assets, liabilities, and disclosures. The estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised if the revision affects only that period or in the period of the revision and future periods if the revision affects both current and future periods.

As of Dec. 31, 2020, the new balance sheet captions “Other non-financial assets” and “Other non-financial liabilities” were created. “Other non-financial assets” was added because of accrued IPO related costs. These new captions also led to reclassifications of transactions from other financial positions. To enhance comparability, these changes were also applied retrospectively to the quarters of the financial year 2020. For further information on the content of these positions, please refer to note (5) and (9).

Diluted earnings per share are calculated by dividing the net income attributable to ordinary shareholders of Atotech Limited by the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares.

Long-term Incentive Plan

Share options to purchase Common Shares were granted beginning in May 2017 to certain employees of the Group pursuant to the Long-term Incentive Plan (“LTIP”). Options were granted with an exercise price that was fixed at the date of the grant. The contractual life and exercise terms of the options are dependent upon an Exit Event, which is defined further in the LTIP agreement. Options were valued using on the basis of an option pricing model, and an estimate of approximate Exit Event timing. The Group has no legal or constructive obligation to repurchase or settle obligations in cash.

The fair value of the awards at the date of grant has been measured using an option pricing model. During the period ended Sep. 30, 2021, no new options were issued.

As of Sep. 30, 2021 and 2020 no share options were exercisable. As of Sep. 30, 2021, a total of 2,042,527 options were outstanding and unvested under the LTIP.

Dissolvement of Management Equity Plan

At the time of the acquisition of Atotech by Carlyle, the Group implemented an equity participation program to enable certain management of the Group to participate in any success of the Group. For this purpose, certain managers acquired interests in three pooling vehicles (the Pooling Vehicles). The three Pooling Vehicles are limited partnerships, with management representing the limited partners (the Participants) and their participation represented by a limited partnership interest in the Pooling Vehicles. The limited partnership interests held by the Participants correspond with the underlying Common Shares held by the Pooling Vehicles. The limited partnership interest of each Participant vests over time in accordance with the partnership agreement.

Since Jan. 31, 2017, the Pooling Vehicles purchased approx. 8.127 million Common Shares and all related expenses were recognized in profit or loss of the Group in the respective years until Dec. 31, 2020. In connection with the consummation of the IPO, the Management Equity Plan was successfully dissolved in accordance with the applicable Investment and Shareholders’ Agreement. Certain Pooling Vehicles were thereby dissolved and a total of approx. 8.127 million common shares were transferred between the remaining Pooling Vehicles and the respective (former) MEP participants.

Matching Share Plan

The Matching Share Plan (“MSP”) is a voluntary employee share plan under which eligible employees have the opportunity to purchase common shares of the Company from their net pay up to two times each year; provided, however, that no employee may contribute over $25,000 to the MSP in one calendar year or, if less, 10% of their gross annual salary. For every four shares an employee purchases under the MSP, the Company adds one matching share at no cost to the employee after a one-year holding period. The program is available to the majority of the Group’s global workforce.

As of Sep. 30, 2021, a total of 36,070 restricted share units were still outstanding and unvested under the MSP.

10

Performance Restricted Share Unit Plan

Performance Restricted Share Units (PSUs) were granted in June 2021 to certain employees of the Company pursuant to the Performance Restricted Share Unit Plan (PRSU). Each PSU represents the right to receive one common share of the Company. The PSUs were granted without an exercise price and will be earned based on the Company’s achievement of defined performance conditions. Thereby, a defined amount of PSUs per participant will be earned based on a performance condition related to the Company’s market value while the remaining amount of PSUs per participant will be earned based on a performance condition related to the Company’s operating profitability.

As of Sep. 30, 2021, a total of 204,134 PSUs were awarded and are still outstanding and unvested under the PRSU.

Restricted Share Unit Plan

Restricted Share Units (RSUs) were granted in June 2021 to certain employees of the Company pursuant to the Restricted Share Unit Plan (TRSU). Each RSU represents the right to receive one common share of the Company. The RSUs were granted without an exercise price and will vest at the completion of defined service periods.

As of Sep. 30, 2021, a total of 372,973 RSUs were awarded and are still outstanding and unvested under the TRSU.

Phantom Share Plan

A total of 30,383 Phantom Shares were granted to two non-executive directors of Atotech. Each Phantom Share represents the right to receive one common share of the Company. The Phantom Shares were granted without an exercise price and will be earned based on a performance condition related to the Company’s market value as well as a service condition related to the completion of a defined service period. In case the defined target market value is not met, each participant will be treated as if they had been granted a number of Phantom Shares equal to a value of $0.5 million.

As of Sep. 30, 2021, a total of 30,383 Phantom Shares are still outstanding and unvested under the Phantom Share Plan.

The following is a summary of the Company’s current and non-current borrowings:

On Feb. 12, 2021, the IPO proceeds were used to repay borrowings (Opco Notes and Holdco Notes) in the amount of $644.0 million. For this purpose, the Group elected to draw down an additional $100.0 million from the existing revolving credit facility (“RCF”). Due to the repayment of the borrowings, an early repayment fee in the amount of $8.8 million was incurred. In total, the Group recorded expenses of $75.6 million during the period ended Sep. 30, 2021 in the consolidated statement of profit or loss, whereby only the early repayment fee was cash-effective. This amount includes the de-recognition of capitalized financing costs and embedded derivatives connected with the borrowings. Please also refer to note (10).

11

Effective on Mar. 18, 2021, the existing RCF was replaced by a new RCF which provides for revolving loans and letters of credit pursuant to commitments in an aggregate principal amount of $250.0 million due in Mar. 2026. Borrowings under the RCF bear interest at a floating rate of 1.00% – 2.00% + IBOR* (floor 0.0%) per annum, depending on the net leverage ratio of the Group determined in accordance with the credit agreement. For undrawn amounts, a commitment fee of 0.25% – 0.375% per annum accrues, depending on the net leverage ratio of the Group determined in accordance with the credit agreement. At Sep. 30, 2021 the Group had $232.5 million out of $250.0 million of available borrowings under its RCF due to the use of $17.5 million of Ancillary Facilities.

Effective on Mar. 18, 2021, the Group completed the early refinancing of its debt. The Term Loans B-1 and B-3 were replaced by a new senior secured term loan structure with a $1,350.0 million tranche (Term Loan B-1: “TL B-1”) and a €200.0 million tranche (Term Loan B-2: “TL B-2”). The terms and conditions of the Term Loans are as follows:

Interest and repayments regarding the Term Loans are paid quarterly, whereas the full principal of TL B-2 is due for repayment on maturity.

Due to the early refinancing of the Group’s debt, capitalized financing costs were de-recognized through profit or loss. Please refer to note (10).

The term loans are collateralized by a material amount of assets of the Group and include covenants that define a maximum net leverage ratio. However, the net leverage ratio is only applicable when the amount drawn is higher than 40% of the total commitment. As of Sep. 30, 2021, no amounts have been drawn on the facility. Hence, the Group was in compliance with all financial covenants through the period to Sep. 30, 2021.

For more information on the refinancing, please also refer to the respective documents filed with the SEC.

The following table shows other current financial and non-financial liabilities:

Please refer to Note (10) for the position fair value of derivatives.
