Naarden, the Netherlands and Miami, USA; November 4, 2026 – NewAmsterdam Pharma Company N.V. (Nasdaq: NAMS or “NewAmsterdam” or the “Company”), a late-stage, clinical biopharmaceutical company developing oral, non-statin medicines for patients at risk of cardiovascular disease (“CVD”) with elevated low-density lipoprotein cholesterol (“LDL-C”), for whom existing therapies are not sufficiently effective or well-tolerated, today provided a corporate update and announced financial results for the quarter ended September 30, 2026.

“The third quarter was marked by significant progress across our regulatory and clinical priorities, including the first regulatory approval of obicetrapib worldwide and the initiation of the SPINOZA Phase 2b trial in preclinical Alzheimer’s disease,” said Michael Davidson, M.D., Chief Executive Officer of NewAmsterdam Pharma. “Looking ahead, we anticipate reaching the predefined event number for the planned PREVAIL interim analysis in the fourth quarter, with the outcome expected in the first quarter of 2027. With PREVAIL, the first cardiovascular outcomes trial evaluating a CETP inhibitor in more than a decade, advancing toward its next major inflection point and top-line data from our Phase 3 RUBENS trial expected around year-end, we look forward to these upcoming readouts as we continue to build the body of evidence supporting obicetrapib across cardiovascular disease and other areas of significant unmet need.”

Commercial Updates

In September 2026, NewAmsterdam and its partner Menarini announced that the European Commission (“EC”) granted marketing authorization for Ubeslo® (obicetrapib 10 mg monotherapy) and Evlarco® (10 mg obicetrapib plus 10 mg ezetimibe fixed-dose combination (“FDC”) for patients with primary hypercholesterolaemia, both heterozygous familial (“HeFH”) and non-familial or mixed dyslipidaemia, marking the first regulatory approval of obicetrapib worldwide. The EC approval followed the positive opinion adopted by the European Medicines Agency’s Committee for Medicinal Products for Human Use (“CHMP”) and was supported by data from NewAmsterdam's comprehensive clinical development program evaluating obicetrapib, including the Phase 3 BROADWAY, BROOKLYN and TANDEM trials, which demonstrated statistically significant LDL-C reductions of up to 40% with obicetrapib monotherapy versus placebo and approximately 50% with obicetrapib combined with ezetimibe versus placebo, with a tolerability profile comparable to placebo.

Under the parties' licensing agreement, Menarini holds exclusive commercialization rights for obicetrapib in Europe and is responsible for regulatory interactions and commercialization activities throughout the region. NewAmsterdam is entitled to tiered double-digit percentage royalties ranging from the low double-digits to mid-twenties on net sales in the Menarini Territory and up to an additional €817 million upon the achievement of various clinical, regulatory and commercial milestones. Menarini plans to launch into Germany by YE2026 and the UK in 2027, additional updates may be provided as launches occur.

Clinical Development Updates

NewAmsterdam is developing obicetrapib, an oral, low-dose, once-daily, highly-selective cholesteryl ester transfer protein (“CETP”) inhibitor, as a monotherapy and in fixed-dose combination with ezetimibe, as the potential preferred LDL-C lowering therapy to be used in patients at risk of CVD for whom existing therapies are not sufficiently effective or well-tolerated.

In August 2026, NewAmsterdam presented three analyses at the European Society of Cardiology (ESC) Congress 2026. The presentations included pooled Phase 3 efficacy data, analyses of Lp(a) variability, and broader research into the clinical implications of elevated HDL-C levels, including the following highlights:

Upcoming Milestones and Ongoing Trials:

Following the successful completion of and positive topline results from the Phase 3 BROADWAY, TANDEM, and BROOKLYN trials, NewAmsterdam plans to announce additional clinical data from these trials relating to obicetrapib and the FDC of obicetrapib plus ezetimibe over the next several quarters.

The following Phase 3 trials are currently ongoing:

In September 2026, NewAmsterdam announced the dosing of the first participant in SPINOZA, a Phase 2b clinical trial evaluating obicetrapib in individuals with preclinical Alzheimer’s disease.

Third Quarter Financial Results

About Obicetrapib

Obicetrapib is a novel, oral, low-dose CETP inhibitor that NewAmsterdam is developing to overcome the limitations of current LDL-lowering treatments. In each of the Company’s Phase 2 trials, ROSE2, TULIP, ROSE, and OCEAN, as well as the Company’s Phase 3 BROOKLYN, BROADWAY and TANDEM trials, evaluating obicetrapib as monotherapy or combination therapy, the Company observed statistically significant LDL-lowering combined with a side effect profile similar to that of placebo. The Company commenced the Phase 3 PREVAIL cardiovascular outcomes trial in March 2022, which is designed to assess the potential of obicetrapib to reduce occurrences of MACE. The Company completed enrollment of PREVAIL in April 2024 and randomized over 9,500 patients. Commercialization rights of obicetrapib in Europe, either as a monotherapy or as part of a fixed-dose combination with ezetimibe, have been exclusively granted to the Menarini Group, an Italy-based, leading international pharmaceutical and diagnostics company.

About Cardiovascular Disease

Cardiovascular disease remains the leading cause of death globally, despite the availability of lipid-lowering therapies (“LLTs”). By 2050 more than 184 million U.S. adults are expected to be affected by CVD and hypertension, including 27 million with coronary heart disease and 19 million with stroke. In the United States from 2019 through 2022, CVD age-adjusted mortality rates increased by 9%, reversing the trend observed since 2010 and undoing nearly a decade of progress. Despite the availability of high-intensity statins and non-statin LLTs, LDL-C target level attainment remains low, contributing to residual cardiovascular risk, and underscoring a significant clinical need for improved therapeutic regimens. Even with 269 million LLT prescriptions written over the last 12 months, around 40 million under-treated US adults are not at their risk-based LDL-C goal, of which 17 million have ASCVD. Less than 1 in 4 patients with ASCVD achieve an LDL-C goal of less than 70 mg/dL and only 20% of very high-risk ASCVD patients achieve the goal below 55 mg/dL. In addition to the 40 million under-treated U.S. adults, there are over 20 million patients diagnosed with elevated LDL-C who are not taking any LLTs including statins. Beyond LDL-C, additional factors are at play, such as lifestyle choices, tobacco use, and obesity, as well as inflammation, thrombosis, triglyceride levels, elevated Lp(a) levels, and type 2 diabetes.

Alzheimer’s Analysis

In BROADWAY, a pre-specified analysis was designed to assess plasma biomarkers of Alzheimer’s disease (“AD”) in patients enrolled in the BROADWAY trial and evaluated the effects of longer duration of therapy (12 months) with a prespecified ApoE population, based on phenotypic analysis. The analysis included 1,535 patients, including 367 ApoE4

carriers (ApoE3/E4 or ApoE4/E4), whose ApoE status was able to be determined. Because this analysis was based on a subset of patients from BROADWAY (which was designed to evaluate LDL-C reductions in an ASCVD and/or HeFH population), the AD analysis was not controlled for baseline differences between the treatment and placebo populations, but statistical analyses were adjusted for baseline biomarker values and age. The absolute and percent change over 12 months in p-tau217, a key biomarker of AD pathology, were measured among patients with baseline and end of study datapoints above the lower limit of quantitation. Additional outcome measures included NFL, GFAP, p-tau181, and Aβ42/40 ratio absolute and percent change over 12 months. NewAmsterdam observed statistically significant absolute reductions in p-tau217 compared to placebo over 12 months in both the full analysis set (p=0.002; n= 1,535) and in ApoE4 carriers (p=0.02; n=367) as well as favorable trends in the other AD biomarkers. Although a safety analysis was not performed in the AD analysis population, in BROADWAY obicetrapib was observed to be well-tolerated, with safety results comparable to placebo.
