These forward-looking statements include, but are not limited to, statements by NewAmsterdam Pharma Company N.V. (“NewAmsterdam” or the “Company”) regarding estimates and forecasts of financial and performance metrics and projections of peak sales opportunities; the Company's business and strategic plans; expectations and timing related to the success, cost and timing of product development activities, including timing of initiation, completion and data readouts for clinical trials and the potential approval of the Company’s product candidate; the timing for enrolling patients; the timing and forums for announcing data; the size and growth potential of the markets for the Company’s product candidate; the therapeutic and curative potential of the Company’s product candidate; financing and other business milestones; the Company’s expected cash runway; scope and duration of patent protections and regulatory exclusivities; and the Company’s plans for commercialization. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of the Company’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions. Many actual events and circumstances are beyond the control of the Company. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political, and legal conditions; risks related to the approval of NewAmsterdam’s product candidate and the timing of expected regulatory and business milestones; whether topline, initial or preliminary results from a particular clinical trial will be predictive of the final results of that trial and whether results of early clinical trials will be indicative of the results of later clinical trials; the potential for varying interpretations of the Alzheimer’s disease sub-study and the results of other trials; the potential for varying interpretations relating to potential drivers of observed MACE reduction; ability to negotiate definitive contractual arrangements with potential customers; the impact of competitive product candidates; ability to obtain sufficient supply of materials; global economic and political conditions; the effects of competition on NewAmsterdam’s future business; and those factors discussed in documents filed by the Company with the SEC. Additional risks related to NewAmsterdam’s business include, but are not limited to: uncertainty regarding outcomes of the company’s ongoing clinical trials, particularly as they relate to regulatory review and potential approval for its product candidate; risks associated with the Company’s efforts to commercialize a product candidate; the Company’s ability to negotiate and enter into definitive agreements on favorable terms, if at all; the impact of competing product candidates on the Company’s business; risks and uncertainties relating to intellectual property and regulatory exclusivities; the Company’s ability to attract and retain qualified personnel; and the Company’s ability to continue to source the raw materials for its product candidate, together with the risks described in the Company’s filings made with the U.S. Securities and Exchange Commission from time to time. If any of these risks materialize or NewAmsterdam’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that are presently unknown by the Company or that NewAmsterdam currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect NewAmsterdam’s expectations, plans, or forecasts of future events and views as of the date of this Presentation and are qualified in their entirety by reference to the cautionary statements herein. NewAmsterdam anticipates that subsequent events and developments will cause the Company’s assessments to change. These forward-looking statements should not be relied upon as representing NewAmsterdam’s assessments as of any date subsequent to the date of this Presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither NewAmsterdam nor any of its affiliates undertakes any obligation to update these forward-looking statements, except as required by law. Market Data Certain information contained in this Presentation relates to or is based on third-party studies, publications, data, surveys and NewAmsterdam’s own internal estimates and research. In addition, all of the market data included in this Presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions.

Tailwinds are Making Lipid Lowering Space More Conducive to Commercial Success 1 Very large opportunity – even small amounts of penetration can result in significant financial success We have seen LLT market growth each year for the last 5 years 2 Non-statin growth continues in the high double digits Shift towards more aggressive treatment using alternatives / adding to statins Observations 3 Guidelines* have shifted to recommend more intense intervention not only with statins, but with ezetimibe, PCSK9’s and bempedoic acid Governing bodies and KOL’s are prioritizing the importance of treating to goal 1.

There are limitations on the interpretation of MACE data derived from both BROOKLYN and BROADWAY studies given they were not designed or powered to assess MACE. MACE data presented above may not be predictive of the MACE data we observe in PREVAIL, which has been designed to measure MACE benefit.

Kaplan-Meier Curve Separates at Day 200 Driven by Attenuation of Events in the Obicetrapib Arm 4-point MACE: CHD death, Non-fatal myocardial infarction, non-fatal stroke, coronary revascularization (1) While not powered to detect a MACE benefit, we observed positive MACE data as part of our review of the exploratory endpoint. BROADWAY was not powered to measure MACE benefit and the MACE data presented below may not be predictive of the MACE data we observe in PREVAIL, which has been designed to measure MACE benefit. Kaplan Meier Curve Landmark Analysis: Censored at 6 months (1)

Explaining BROADWAY’s Observed 21% MACE Reduction Based on the CTT line, the expectation for a 33% reduction in LDL-C from placebo would be a 9% MACE reduction, after 12 months LDL-P reduction potentially provides 6-7% additional MACE reduction Lp(a) reduction potentially provides an additional 5% MACE reduction These elements may not be additive as they are correlated to some extent. In this scenario, there is room for additional reduction to be driving incremental gains LDL-C Alone LDL-P 9% 21% 1% Lp(a) 5% 6% Potential Drivers ObservedMACE Additional Reduction Obicetrapib’s Observed MACE Reduction Methods of Estimating MACE Reduction Note: Actual results may differ from hypothetical calculation.

+ Elevated Cholesterol Levels in the Brain Precede Formation of Amyloid-Beta (Aβ) Plaques During early development, oligodendrocytes synthesize large quantities of cholesterol for myelination In adults, when myelination is complete, glial cells and, to a lesser extent, neurons account for the steady-state production of cholesterol The brain uses a unique mechanism for cholesterol recycling and redistribution Involves an ApoE-mediated lipoprotein pathway unique to the CNS whereby cholesterol is turned over Excess oxysterols are ultimately delivered to the liver for secretion into the bile Cholesterol itself does not exit the brain but instead is converted to a metabolite, 24S-hydroxycholesterol 24S-hydroxycholesterol is a proxy for excess cholesterol that will be measured in our phase 2a clinical trial 20% cholesterol APOE, apolipoprotein E; CNS, central nervous system.
