NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 Group Information

NewAmsterdam Pharma Company N.V. (the Company and together with its subsidiaries, the Group ) is a global biotechnology company focused on the research and development of transformative therapies for cardio-metabolic diseases. The Company was incorporated in the Netherlands as a Dutch private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) under the name NewAmsterdam Pharma Company B.V. on June 10, 2022. On November 21, 2022, in connection with its merger with Frazier Life Sciences Acquisition Corp ( FLAC ), the Company's corporate form was converted to a Dutch public limited liability company (naamloze vennootschap) and its name was changed to NewAmsterdam Pharma Company N.V. The Group's principal place of business and registered office is Gooimeer 2-35, 1411 DC Naarden, The Netherlands. These unaudited condensed consolidated financial statements comprise the financial statements of the Group.

Terms in these accompanying notes take on the same meaning as defined in the Company's Annual Report on Form 20-F for the year ended December 31, 2022 filed with the U.S. Securities and Exchange Commission on March 31, 2023 (the Annual Report ), unless otherwise defined.

Note 2 Basis of Preparation and Summary of Material Accounting Policy Information

Basis of Preparation

These unaudited condensed consolidated financial statements as at June 30, 2023 and for the six months ended June 30, 2023 and 2022 should be read in conjunction with the Annual Report as the unaudited condensed consolidated financial statements are prepared on a condensed basis in accordance with IAS 34 Interim Financial Reporting and do not contain all information required for a complete set of financial statements prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board ( IFRS ). Unless stated otherwise, the unaudited condensed consolidated financial statements as at June 30, 2023 and for the six months ended June 30, 2023 and 2022 are presented on a basis consistent with the accounting policies set out in the Annual Report.

There were no significant changes in accounting policies, critical accounting judgements and key sources of estimation uncertainty applied by us in these unaudited condensed consolidated financial statements compared to those used in the Annual Report.

The unaudited condensed consolidated financial statements have been prepared on a historical cost basis, unless otherwise disclosed. The unaudited condensed consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern, and which contemplates the recoverability of assets and the satisfaction of the liabilities and commitments in the normal course of business.

Based on the Group's current operating plan, management has assessed that the existing cash and cash equivalents will be sufficient to fund the Group's anticipated level of operations for the twelve months following the date of the issuance of these financial statements.

The functional currency of the Group has historically been EUR. In the first half of 2023, the Group reassessed its functional currency and determined the United States Dollar ( USD or $ ) to be the Group's functional currency beginning January 1, 2023. Significant elements involved in the determination of the functional currency change include a shift in the Group's sources of financing from EUR to USD given its access to the U.S. public market and an increase of operating costs incurred in USD due to Phase III trials taking place predominantly in the United States, among other factors. Given these significant changes, management considered the economic factors outlined in IAS 21, The Effects of Changes in Foreign Exchange Rates and concluded that the majority of the factors supported the determination of the USD as the functional currency.

The unaudited condensed consolidated financial statements are presented in Euro ( EUR or ). In these notes, Euro amounts are presented in thousands, except for share and per share amounts and as otherwise indicated. The Company has elected to present its financial statements in EUR in order to provide information comparable to the historical financial information included within previous Company filings.

New and Amended IFRS Standards that are Effective for the Current Year

New standards and interpretations effective for the annual period beginning on January 1, 2023 did not have any material impact on the Company's condensed consolidated financial statements.

New Standards, Interpretations and Amendments Issued but Not Yet Adopted by the Company

At the date of authorization of these financial statements, the Group has not applied new and revised IFRS Standards that have been issued but are not yet effective. The amendments to the standards and interpretations presented are not expected to have a material impact on the consolidated financial statements in future periods.

The Group earns revenue through a license agreement with A. Menarini International Licensing S.A. ( Menarini ) (the Menarini License ), pursuant to which it granted Menarini an exclusive, royalty-bearing, sublicensable license under certain of its intellectual property and its regulatory documentation to undertake post approval development activities and commercialize multiple brands of obicetrapib. The Menarini License includes a non-refundable upfront payment, fixed reimbursements for the Group's continued development costs, payments based upon the achievement of defined development, regulatory and commercial milestones, sales-based royalties, and certain cost sharing payments made by Menarini to the Group and by the Group to Menarini.

In January 2023, the Group achieved a clinical milestone related to our Phase 2 ROSE2 clinical trial which resulted in a 5 million milestone payment from Menarini in April 2023. Revenues related to the achievement of milestones under the Menarini License are attributed to the license performance obligation.

Revenue consisted of the following for the six months ended June 30:

At January 1, 2023, the Group had total deferred revenue of 17.5 million. During the six months ended June 30, 2023, 4.6 million of the deferred revenue was recognized as revenue and a translation difference of approximately 0.3 million further reduced the deferred revenue liability. No additional deferred revenue was recognized during the period. The deferred revenue has been recognized within current and non-current liabilities based on the expected timing of the associated research and development services. In connection with the Menarini License, 9.7 million is recognized within current liabilities as the Company expects to perform the associated services within twelve months after the reporting period and the remaining 2.9 million is recognized within non-current liabilities as of June 30, 2023.

Note 4 Research and Development Expense

Research and development expense consisted of the following items for the six months ended June 30:

Note 5 Selling, General and Administrative Expenses

Selling, general and administrative expenses consisted of the following items for the six months ended June 30:

Note 6 Financial Risk Management

The Group's risk management activities are the same as those disclosed in our Annual Report.

The table below summarizes the maturity profile of the Group's financial liabilities based on contractual undiscounted payments. Payments related to foreign currency are included at the exchange rates applicable as at June 30, 2023.

Note 7 Financial Assets and Liabilities Fair Value

Financial liabilities consist of trade and other payables, lease liability, derivative warrant liabilities and derivative earnout liability.

The carrying amount of cash, trade and other payables approximate their fair value due to their short-term nature. The fair values of these financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Lease liabilities are measured at amortized cost based on the present value of the contractual payments due to the lessor over the lease term.

Derivative Warrant Liabilities

At January 1, 2023 a total of 167,000 Private Placement Warrants and 4,600,000 Public Warrants (collectively, the Warrants ) were outstanding. In the six months ended June 30, 2023, no new warrants were issued and 749,679 were exercised at a price of $11.50 per ordinary share, nominal value 0.12 per share, of the Company (the Ordinary Shares ), for total proceeds of 8.0 million. At June 30, 2023, the Company had 3,850,321 and 167,000 Public Warrants and Private Placement Warrants outstanding, respectively.

The fair value of the outstanding Warrants increased from $0.87 per warrant as of December 31, 2022 to $2.09 per warrant at June 30, 2023. At the moment of exercise, the fair value of a Warrant is calculated as the difference between the exercise price and the closing price on the date of exercise of an Ordinary Share trading on Nasdaq under the ticker NAMS. For the six months ended June 30, 2023, the Group recognized a charge of 5.4 million in profit or loss, which has been presented as a change in the fair value of derivative warrant liabilities under fair value change derivative earnout and warrants expense.

Derivative Earnout Liability

The Business Combination Agreement contemplates the issuance of Earnout Shares, totaling 1,886,137 Ordinary Shares, contingent upon the achievement of a development milestone. At December 31, 2022, 1,725,358 Earnout Shares were allocated to Participating Shareholders. During the period a Participating Optionholder forfeited their rights with respect to a total of 409 Earnout Shares. These shares were reallocated pro rata among the remaining pool of Earnout Shares. As a result, at June 30, 2023 an additional 374 Earnout Shares were allocated to Participating Shareholders for a total of 1,725,732 Earnout Shares.

At December 31, 2022, the fair value of the 1,725,358 Earnout Shares allocated to Participating Shareholders was 7.1 million. At June 30, 2023, the fair value of the 1,725,732 Earnout Shares allocated to Participating Shareholders was 7.6 million. The remeasurement of the financial liability resulted in a charge of 0.6 million in profit or loss, which has been presented as a change in the fair value of derivative warrant liabilities under fair value change derivative earnout and warrants expense.

Fair value measurements

The financial liability for the derivative warrants is accounted for at fair value through profit or loss. The Public Warrants are considered liquid and are actively listed on Nasdaq and have been measured at fair value using the quoted price (Level 1).

The Private Placement Warrants have been measured at fair value using inputs other than quoted prices included in Level 1 that are observable for the liability (Level 2), since the terms of the Private Placement Warrants are considered to be nearly identical to the Public Warrants, and the Public Warrants have an observable price in the active market. For these reasons, the measurement of the Private Placement Warrants can be indirectly derived from the quoted price of the Public Warrants.

Based upon an assumed zero dividend rate and the fact that no strike price exists that would have led to any volatility measure relative to the Company's share price, the fair value of the Earnout Shares allocated to Participating Shareholders resulting from the Black-Scholes pricing model is driven by the Company's closing share price as a Level 1 input and the probability of milestone completion, estimated by management to be 40%, as a Level 3 input. As management's judgment of the probability of milestone completion remained constant during the period, the change in fair value resulted from the Company's price per share between the valuations performed at December 31, 2022 and at June 30, 2023. The resulting per share fair value of the Earnout Shares allocated to Participating Shareholders is 4.38 at June 30, 2023, compared to a per share fair value of 4.09 at the December 31, 2022.

The following table shows the carrying amounts of the financial liabilities measured at fair value through profit and loss on a recurring basis:

Note 8 Share Capital and Share Premium

During the six months ended June 30, 2023, the Group issued 749,641 Ordinary Shares upon the exercise of Warrants and 14,910 Ordinary Shares upon the exercise of Company Options. The exercise of Warrants resulted in an increase of share capital and share premium of 90 thousand and 9.3 million, respectively. The exercise of Company Options resulted in an increase of share capital and share premium of 2 thousand and 138 thousand, respectively.

Note 9 Share-Based Payments

The Company has three Share-based payment plans and one restricted share award in place as at June 30, 2023:

-The Company's Long-Term Incentive Plan (the Plan );

-The Company's Supplementary Long-Term Incentive Plan (the Supplementary Plan );

-the Company's Rollover Option Plan (the Rollover Plan, together with the Plan and the Supplementary Plan, the Plans ); and

-Chief Executive Officer Restricted Share Award.

Long Term Incentive Plans

The Plans are equity-settled, and the Company may grant various forms of equity awards, including the granting of options to purchase Ordinary Shares ( Company Options ) and restricted stock units ( RSUs ), pursuant to the Plans.

The contractual term is 10 years from grant date for options granted under the Plans In general, each Company Option granted in 2023 has a four-year vesting period with 25% vesting after one year and the remaining 75% vesting in equal monthly installments over the next following three years.

The changes for the six months ended June 30, 2023 in the number of options outstanding related to Ordinary Shares and their related weighted average exercise prices are as follows:

As at June 30, 2023, 4,189,605 of the outstanding Company Options are exercisable. The options outstanding as of June 30, 2023 have a weighted average remaining contractual life of 9.0 years.

Fair Value of Options Granted

The Black-Scholes option pricing formula has been applied for measuring the fair value of the options granted. The weighted average fair values and the inputs (ranges) used in the measurement of the fair values of these equity-settled options at the date of grant are summarized below:

The expected option life is based on management's best estimate of when the options will be exercised. Expected volatility is estimated by considering historical average share price volatility of a group of comparable companies over a period before the grant date being equal to the expected option life. The expected dividend rate is zero as the Company currently has no history or expectation of declaring dividends on its ordinary shares. The risk-free interest rate is based upon the U.S. Treasury yield curve in effect at the time of grant, with a term that approximates the expected life of the option.

Share-Based Payment Expenses Recognized for Options Granted

The fair value of the options is expensed over the relevant vesting periods using the graded vesting method, based on management's estimate of the number of options that will eventually vest. For the six months ended June 30, 2023 and 2022, the total share-based payment expense recognized for the equity-settled options amounted to 12.1 million and 0.3 million, respectively.

In addition, during the six months ended June 30, 2023 and 2022, the Group recognized 1.1 million and 0.0million, respectively, as expenses for the employer social security contributions expected to be payable related to these options. The corresponding liability as at June 30, 2023 and December 31, 2022 amounts to 2.8 million and 0.1 million, respectively.

Restricted Stock Units ( RSUs )

As at June 30, 2023 the Company had allocated 160,404 Earnout Shares to be granted to participants in the Plan who were directors, officers, employees or consultants of NAP B.V. as of the date of the Business Combination Agreement and who are at the time of the achievement of such milestone providing services to the Company or its subsidiaries ( Participating Optionholders ) if and when a certain clinical development milestone is achieved during the earnout period. These Earnout Shares will be delivered in the form of awards of RSUs granted pursuant to the Plan to such Participating Optionholders who are at the time of achievement of such milestone still providing services to the Group.

The development milestone consists of the achievement and public announcement of Positive Phase 3 Data for each of the Company's BROADWAY clinical trial and BROOKLYN clinical trial at any time during the period beginning on November 22, 2022 and ending on the date that is five years after such date.

There is no impact on these financial statements with respect to these RSUs due to the uncertainty of achieving the clinical development milestone.

Chief Executive Officer Restricted Share Award

In July 2021, our chief executive officer, Michael Davidson, M.D., paid the fair market value of the underlying ordinary shares (in aggregate 708,571) when he made an investment in restricted shares issued through Depositary Receipts as previously disclosed. Accordingly, the total fair value of these equity-settled share-based payment awards amounts to nil and there will be no expenses recognized in the income statement. This award had a four year vesting period with 25% vesting on August 1, 2021 and the remaining 75% vesting in equal monthly installments over the following three years.

In connection with the award arrangement, if Dr. Davidson leaves the Group, all unvested Ordinary Shares will be cancelled against payment by the Company to him of the lower of the (i) the purchase price paid and (ii) the fair market value of such Ordinary Shares at the time of forfeiture. In order to reflect the consideration paid and the possibility that the Ordinary Shares would be repurchased if Dr. Davidson becomes a Good Leaver (as such term is defined in the award agreement) during the vesting period, the Company has recognized the consideration as a financial liability until the award has fully vested, at which time it will be reclassified to equity provided that Dr. Davidson remains with the Group. This liability is measured at the lower of (i) the purchase price paid and (ii) the fair market value of the Ordinary Shares at the end of the reporting period. The liability for unvested Ordinary Shares as at June 30, 2023 amounted to 192 thousand.

For the six months ended June 30, 2023, the movements in the number of Ordinary Shares outstanding are as follows:

As of June 30, 2023, a total of 443,901 Ordinary Shares had vested.

Note 10 Earnings per Share

Earnings per share for the period presented has been determined by dividing the earnings attributable to shareholders by the weighted average number of shares outstanding during the period. NewAmsterdam Pharma's former non-voting ordinary shares and voting ordinary shares are considered to be the same class of equity for purposes of determining the loss attributable per shareholder class per share.

In accordance with the Business Combination Agreement, 17,016,872 NewAmsterdam Pharma shares were exchanged for 36,258,312 Ordinary Shares following the internal reorganization, which reflects the exchange ratio of approximately 2.13. Consequently, the weighted average number of Ordinary Shares outstanding for basic and diluted EPS for the prior period has been restated as required by IFRS.

In total, 1,964,286 NewAmsterdam Pharma Options were outstanding as of January 1, 2022 and as of June 30, 2022. At the time of the Exchange these were converted into 4,185,360 Company Options. The table below reflects the original and restated number of options in the diluted number of Ordinary shares, as appropriate.

The following table sets forth the computation of original and restated basic and diluted loss per share for the six months ended June 30:
