Summary of Significant Accounting Policies (Policies)	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements should be read together with the Company's audited financial statements and accompanying notes for year ended December 31, 2023, included in the Company's Annual Report on Form 10-K (the "Annual Report"), filed with the SEC on February 28, 2024. Any terms not defined herein take the meaning as defined in the Annual Report. The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2023 included herein has been derived from the audited financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments which are necessary for a fair statement of the Company’s financial information. The interim results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other interim period or for any other future year. The unaudited condensed consolidated financial statements comprise the financial statements of the Company and its subsidiaries. Any reference in these notes to the applicable guidance is meant to refer to authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, after elimination of intercompany accounts and transactions. Prior to 2023, the Company prepared its financial statements in accordance with the International Financial Reporting Standards as issued by the International Accounting Standard Board (“IFRS”) as permitted in the United States based on the Company’s qualification as a foreign private issuer under the rules and regulations of the SEC. In connection with the loss of the Company’s status as a foreign private issuer effective on January 1, 2024, the Company, as a domestic filer, prepared these financial statements in accordance with U.S. GAAP. The transition to U.S. GAAP was made retrospectively for all periods from the Company’s inception. Except for the policy described below, the accounting policies of the Company are consistent with those described in Note 2 of the consolidated financial statements included within the Annual Report.
Net Loss Per Share	Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of Ordinary Shares outstanding during the period. For the purposes of calculating the weighted-average number of Ordinary Shares outstanding, the Ordinary Shares underlying the Pre-Funded Warrants issued in the Offering (as defined in Note 7 below) are included. Diluted net loss per share is the same as basic net loss per share, since the effects of potentially dilutive securities are antidilutive given the net loss for each period presented.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

The Company

Note 1. The Company

NewAmsterdam Pharma Company N.V. (“NewAmsterdam Pharma” or the “Company”) is a late-stage biopharmaceutical company whose mission is to improve patient care in populations with metabolic diseases where currently approved therapies have not been adequate or well-tolerated. 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, 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 Company’s ordinary shares, nominal value €0.12 per share (the "Ordinary Shares") are listed on the Nasdaq Global Market ("Nasdaq") and trade under the symbol “NAMS.”

The Company is subject to risks and uncertainties common to early-stage companies in the biopharmaceutical industry, including, but not limited to, development by competitors of more advanced or effective therapies, dependence on key executives, protection of and dependence on intellectual property, compliance with government regulations and ability to secure additional capital to fund operations. Significant additional research and development efforts and regulatory approval will be required prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 4. Fair Value Measurements

As at September 30, 2024 and December 31, 2023, the Company’s financial liabilities recognized at fair value on a recurring basis consisted of the following:


	As at September 30, 2024
(In thousands of USD)	Level 1		Level 2		Level 3		Total
Derivative warrant liability (Public Warrants)		17,732		—		—		17,732
Derivative warrant liability (Private Placement Warrants)		—		1,169		—		1,169
Derivative earnout liability		—		—		18,808		18,808
Total financial liabilities		17,732		1,169		18,808		37,709


	As at December 31, 2023
(In thousands of USD)	Level 1		Level 2		Level 3		Total
Derivative warrant liability (Public Warrants)		12,051		—		—		12,051
Derivative warrant liability (Private Placement Warrants)		—		523		—		523
Derivative earnout liability		—		—		7,788		7,788
Total financial liabilities		12,051		523		7,788		20,362

The estimated fair value of the derivative earnout liability was determined using Level 3 inputs, other than the Company's share price as a Level 1 input, as no observable market inputs were available. The derivative earnout liability has been measured at fair value using a Black-Scholes pricing model. Given the 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 liability resulting from the Black-Scholes pricing model is entirely driven by the Company’s closing share price as a Level 1 input and the probability of milestone completion as a Level 3 input. As such, the relevant inputs to the fair value of the derivative earnout liability are as follows:


	September 30, 2024			December 31, 2023
Ordinary Share value (USD)	$	16.60		$	11.17
Probability of milestone completion		65	%		40	%
Dividend yield		0	%		0	%
Strike price (USD)		0.00			0.00

On July 29, 2024 the Company announced positive topline results from its Phase 3 BROOKLYN clinical trial. Positive results from the BROOKLYN trial is a component of the milestone which is required in order for the Earnout Shares to be granted. The Company has determined that the reporting of positive data from the BROOKLYN clinical trial increases the probability of achieving the milestone from 40% to 65%. The change in fair value results from the increase in the probability of achieving the milestone, a Level 3 input, and the change in the Company's Ordinary Share value between valuation dates.

The following table presents a reconciliation of the derivative earnout liability measured on a recurring basis using Level 3 inputs as of September 30, 2024:

All changes in fair value recognized in the statement of operations are unrealized. There were no sales, purchases, settlements or transfers into or out of Level 3 of the fair value hierarchy related to the derivative earnout liability during the period ended September 30, 2024.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Note 8. Share-Based Compensation

The Company has four share-based payment plans and one restricted share award in place as at September 30, 2024:

•

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,”);

•

The Company’s Inducement Plan (the “Inducement Plan,” together with the Plan, the Supplementary Plan and the Rollover Plan, the “Plans”); and

•

Chief Executive Officer Restricted Share Award.

The 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. In total, as of September 30, 2024 a maximum of 22,049,356 Ordinary Shares may be reserved for issuance pursuant to the Plans. The number of Ordinary Shares reserved for grant under the Plan will increase annually on January 1 of each calendar year by 5% of the then issued and outstanding Ordinary Shares or such lower number as may be determined by the Company's Board of Directors.

The contractual term is 10 years from grant date for options granted under the Plans. In general, each Company Option 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.

Modification of Options During the Period

In 2024, a total of 399,153 Company Options granted to one employee were modified. For 210,655 of the modified Company Options the vesting period was shortened, of which 200,655 such modified Company Options also had the exercise period extended. For the other 188,498 modified Company Options only the exercise period was extended.

The total fair value of the 210,655 modified Company Options for which the vesting period was shortened is equal to $1.2 million. Any expense previously recognized for such Company Options was reversed on the modification date and the full fair value of the modified Company Options is recognized over the applicable service period. For the 188,498 modified Company Options for which only the exercise period was extended the total fair value of the modification is equal to $0.1 million, all of which is recognized on the modification date.

The changes for the nine months ended September 30, 2023 in the number of Company Options outstanding related to Ordinary Shares and their related weighted average exercise prices are as follows:


	Number of options			Weighted average exercise price		Weighted average remaining contractual term (in years)		Aggregate intrinsic value (in thousands of USD)
Outstanding as at December 31, 2023		15,783,509		$	7.98
Granted		4,988,848		$	14.06
Exercised		(591,403	)	$	1.27
Forfeited		—		$	-
Outstanding as at September 30, 2024		20,180,954		$	9.68		8.3		145,756
Options exercisable as at September 30, 2024		7,820,112		$	6.49		7.6		79,035

The weighted average grant date fair value of Company Options, estimated as of the grant date using the Black-Scholes option pricing model, was $6.60, and $4.83 per option for options granted during the nine months ended September 30, 2024 and 2023, respectively. The total intrinsic value (the amount by which the fair market value exceeded the exercise price) of Company Options exercised during the nine months ended September 30, 2024 and 2023 was $8.7 million and $1.7 million, respectively. Weighted average assumptions used to apply this pricing model were as follows:


	Nine months ended September 30,
	2024			2023
Expected life (years)		6.1			6.1
Risk-free rate		3.9	%		4.0	%
Volatility		41.7	%		38.3	%
Dividend yield		0.0	%		0.0	%

Expected Term

The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term). The Company utilizes this method due to lack of historical exercise data and the plain-vanilla nature of the Company’s stock-based awards.

Expected Volatility

Since the Company was privately held through November 2022, it alone does not have sufficient relevant company-specific historical data to support its expected volatility alone. In prior periods, due to the insufficiency of historical volatility data on the Company’s own securities, the expected volatility input was determined using comparable companies alone. Beginning on January 1, 2024 expected volatility input was determined using a weighted average calculation considering the volatility of the Company’s own securities and the volatilities of a representative group of publicly traded biopharmaceutical companies over a period equal to the expected term of the stock option grants. Initially, the volatility of the Company’s Ordinary Shares is assigned a weighting of 10%. This weighting will be increased by 5% per calendar quarter until the expected volatility input is based entirely on the historical volatility of the Company’s Ordinary Shares. For purposes of identifying comparable companies, the Company selected companies with comparable characteristics to it, including enterprise value, risk profiles, position within the industry, and with historical share price information sufficient to meet the expected life of the stock-based awards. The historical volatility data was computed using the daily closing prices for the selected companies’ shares during the equivalent period of the calculated expected term of the stock-based awards.

Risk-Free Interest Rate

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 Company Option.

Expected Dividend

The expected dividend rate is zero as the Company currently has no history or expectation of declaring dividends on its Ordinary Shares.

Share-based compensation is classified in the consolidated statement of operations and comprehensive loss as follows:


	Three months ended September 30,				Nine months ended September 30,
(in thousands of USD)	2024		2023		2024		2023
Research and development expenses		3,043		3,273		9,514		11,492
Selling, general and administrative expenses		4,953		2,119		14,690		7,074
Total		7,996		5,392		24,204		18,566

As of September 30, 2024, there was $33.4 million of unrecognized compensation cost related to Company Options that have not yet vested. These costs are expected to be recognized over a weighted average period of 3.0 years until fully vested.

Restricted Stock Units

As at September 30, 2024 and December 31, 2023, the Company had allocated 143,002 Earnout Shares to be granted to 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 Company.

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, the Company's chief executive officer, Michael Davidson, M.D., paid the fair market value of the underlying Ordinary Shares (in aggregate $838,806) when he made an investment in restricted shares issued through Depositary Receipts. 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 Company, 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 Company. 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 September 30, 2024 and December 31, 2023 amounted to nil and $0.1 million, respectively.

For the nine months ended September 30, 2024, the movements in the number of Ordinary Shares outstanding are as follows:

As of September 30, 2024 and December 31, 2023, a total of 608,779 and 519,999 Ordinary Shares had vested, respectively.

Summary of Significant Accounting Policies	9 Months Ended
Summary of Significant Accounting Policies	Sep. 30, 2024
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements should be read together with the Company's audited financial statements and accompanying notes for year ended December 31, 2023, included in the Company's Annual Report on Form 10-K (the "Annual Report"), filed with the SEC on February 28, 2024. Any terms not defined herein take the meaning as defined in the Annual Report. The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of December 31, 2023 included herein has been derived from the audited financial statements at that date but does not include all of the information required by U.S. GAAP for complete financial statements. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments which are necessary for a fair statement of the Company’s financial information. The interim results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any other interim period or for any other future year. The unaudited condensed consolidated financial statements comprise the financial statements of the Company and its subsidiaries. Any reference in these notes to the applicable guidance is meant to refer to authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, after elimination of intercompany accounts and transactions. Prior to 2023, the Company prepared its financial statements in accordance with the International Financial Reporting Standards as issued by the International Accounting Standard Board (“IFRS”) as permitted in the United States based on the Company’s qualification as a foreign private issuer under the rules and regulations of the SEC. In connection with the loss of the Company’s status as a foreign private issuer effective on January 1, 2024, the Company, as a domestic filer, prepared these financial statements in accordance with U.S. GAAP. The transition to U.S. GAAP was made retrospectively for all periods from the Company’s inception. Except for the policy described below, the accounting policies of the Company are consistent with those described in Note 2 of the consolidated financial statements included within the Annual Report. Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted-average number of Ordinary Shares outstanding during the period. For the purposes of calculating the weighted-average number of Ordinary Shares outstanding, the Ordinary Shares underlying the Pre-Funded Warrants issued in the Offering (as defined in Note 7 below) are included. Diluted net loss per share is the same as basic net loss per share, since the effects of potentially dilutive securities are antidilutive given the net loss for each period presented.

Net Loss per Ordinary Share

Note 9. Net Loss per Ordinary Share

For the purposes of calculating the weighted-average number of Ordinary Shares outstanding, the Ordinary Shares underlying the Pre-Funded Warrants issued in the Offering are included.

Basic and diluted net loss per Ordinary Share was calculated as follows:


	Three months ended September 30,						Nine months ended September 30,
(In thousands of USD, except share and per share amounts)	2024			2023			2024			2023
Net loss		(16,647	)		(47,133	)		(149,421	)		(127,442	)
Weighted average Ordinary Shares outstanding, basic and diluted		94,754,140			82,466,584			92,666,874			82,058,225
Net loss per Ordinary Share, basic and diluted		(0.18	)		(0.57	)		(1.61	)		(1.55	)

The following potentially dilutive securities have been excluded from the computation of diluted weighted-average Ordinary Shares outstanding as they would be anti-dilutive:


	As at September 30,
	2024		2023
Stock options		20,180,954		14,751,425
Outstanding warrants		2,700,152		4,017,221
