**Amarin Reports Fourth Quarter and Full Year 2025 Financial Results**

*Strategic Initiatives and Refined Business Model Produced Financial and Operating Efficiencies* 

*Established Long-Term License and Supply Agreement to Commercialize VAZKEPA® Across Europe and Sustained U.S. Market Leadership for VASCEPA® Franchise*

*Total of 45 Publications (Abstracts, Posters, Manuscripts) Furthering the Expansion of the VASCEPA® /VAZKEPA® (icosapent ethyl) Body of Knowledge Supported in 2025*

**DUBLIN, Ireland and BRIDGEWATER, N.J., February 25, 2026 --** Amarin Corporation plc (NASDAQ: AMRN), a company committed to advancing the science of cardiovascular disease worldwide, today announced financial results for the fourth quarter and full year ended December 31, 2025.

"Our performance in the fourth quarter and full year of 2025 confirmed both the initial impact and long-term potential of our strategic initiatives and re-imagined operating model," said Aaron Berg, President and Chief Executive Officer of Amarin. "We have entered 2026 from an improved position of market, operational, and financial strength. We have maintained our U.S. leading market share for VASCEPA and are actively expanding our presence in Europe for VAZKEPA via our long-term partnership agreement with Recordati S.p.A., strengthening our now fully partnered international commercial strategy. We are a leaner organization, having made great progress in reducing costs and narrowing our losses, while continuing to invest in expanding an already formidable body of scientific knowledge that supports our global VASCEPA/VAZKEPA franchise and its proven ability to reduce cardiovascular risk. While work remains, we are encouraged by our progress and continue to examine strategic actions to maximize future shareholder value and options regarding management of capital."

*NM – Not Meaningful*

Peter Fishman, Amarin's Chief Financial Officer, said, "Our fourth quarter performance reflects our early success in optimizing the Company's operations and creating what we believe is a more efficient platform for long-term growth. We realized $31 million of the expected $70 million in cost savings from our restructuring initiatives and

------

have incurred nearly all of the $37 - $40 million in restructuring costs. Our cash position improved sequentially and year over year, ending 2025 with total cash and investments of $303 million and no debt. As a direct result of our continued revenue generation and new financial operating profile, our return to positive cash flow in the fourth quarter was ahead of schedule and has positioned us to generate positive cash flow for the full year ahead. We are well positioned to deliver on our operational and strategic priorities in 2026."

---

*NM – Not Meaningful*

**Total Net Revenue:** Decreased $13.1 million, or 21%, due primarily to a decline in ROW sales that reflected a $7.8 million stocking order in last year's fourth quarter in preparation for a market launch, a decline in net selling price in the U.S., and the effects of the transition of our European sales activities to Recordati that included both supply shipments and direct sales in the 2025 fourth quarter. European sales in the fourth quarter of 2024 included direct sales only; once the transition to a fully partnered sales model is complete, European sales will consist only of supply shipments to Recordati. Royalties increased by $0.5 million due to higher in-market sales generated by our global partners.

---

 *\* Total operating expenses reflect the sum of SG&A, R&D, and Restructuring expenses.*

*NM – Not Meaningful*

**Total Operating Expenses:** Decreased $13.5 million, or 31%, primarily due to the impact of the June 2025 Global Restructuring Plan that produced declines in Selling, General, and Administrative expenses (SG&A). Excluding the restructuring charge of $4.1 million (*see discussion below*), Q4 2025 total operating expenses were $25.4 million, representing a decline of 41%.

------

**COGS:** Decreased $45.8 million, or 64%. COGS in Q4 2024 included a one-time inventory restructuring charge of $36.5 million related to the Company's efforts to amend supplier agreements to align with then current and expected future demand and a one-time inventory write-off. Excluding these one-time charges, Q4 2025 COGS decreased $2.8 million, or 10%, primarily due to lower net product sales.

**SG&A:** Decreased $16.9 million, or 46%, primarily due to a reduction in costs pursuant to the Global Restructuring Plan and other cost optimization initiatives.

**R&D:** Consistent with the prior year period.

**Restructuring:** The Company recognized $4.1 million in Q4 2025 related to the continued implementation of the Global Restructuring Plan associated with the execution of the Recordati Licensing Agreement announced in June 2025. This resulted in the elimination of commercial roles in the Company's Europe operations, among other operating expense savings across the Company's global operations. The Company incurred $36.2 million of restructuring charges in full year 2025 and continues to expect total restructuring charges to range from $37 to $40 million, with the remaining charges expected to be realized in early 2026.

**<u>Additional Q4 2025 Financial Information</u>**

*Comparisons to Q4 2024, unless otherwise stated* 

**Operating Loss:** Narrowed to $6.3 million from an operating loss of $52.5 million, an improvement of $46.2 million, or 88%. Operating loss in Q4 2025 included restructuring costs of $4.1 million compared to $36.5 million in Q4 2024.

**Net Loss:** Improved to $(1.2) million, or $(0.00) per share, from a net loss of $(48.6) million, or $(0.12) per share.

**Cash:** Reported aggregate cash and investments of $302.6 million, as of December 31, 2025, compared to $294.2 million as of December 31, 2024, reflecting a year-over-year increase of $8.4 million, and compared to $286.6 million as of September 30, 2025, reflecting a sequential increase of $16.0 million.

**Debt:** Remained debt free as of December 31, 2025.

**About VASCEPA®/VAZKEPA® (icosapent ethyl) Capsules** 

VASCEPA (icosapent ethyl) capsules are the first prescription treatment approved by the U.S. Food and Drug Administration (FDA) comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was launched in the United States in January 2020 as the first drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk despite being on statin therapy. VASCEPA was initially launched in the United States in 2013 based on the drug's initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed more than twenty-five million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, China, Australia, Lebanon, the United Arab Emirates, Saudi Arabia, Qatar, Bahrain, and Kuwait. In Europe, in March 2021 marketing authorization was granted to icosapent ethyl in the European Union for the reduction of risk of cardiovascular events in patients at high cardiovascular risk, under the brand name VAZKEPA. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in the United Kingdom (applying to England, Scotland, Wales, and Northern Ireland). VAZKEPA (icosapent ethyl) is currently approved and sold in Europe in Sweden, Finland, England/Wales, Spain, Netherlands, Scotland, Greece, Portugal, Italy, Denmark and Austria.

**United States<br>Indications and Limitation of Use** 

VASCEPA is indicated:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•As an adjunct to maximally tolerated statin therapy to reduce the risk of myocardial infarction, stroke, coronary revascularization and unstable angina requiring hospitalization in adult patients with elevated triglyceride (TG) levels (≥ 150 mg/dL) and

oestablished cardiovascular disease or

odiabetes mellitus and two or more additional risk factors for cardiovascular disease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•As an adjunct to diet to reduce TG levels in adult patients with severe (≥ 500 mg/dL) hypertriglyceridemia.

The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined.

**Important Safety Information** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial. The incidence of bleeding was greater in patients receiving concomitant antithrombotic medications, such as aspirin, clopidogrel or warfarin.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Common adverse reactions in the cardiovascular outcomes trial (incidence ≥3% and ≥1% more frequent than placebo): musculoskeletal pain (4% vs 3%), peripheral edema (7% vs 5%), constipation (5% vs 4%), gout (4% vs 3%), and atrial fibrillation (5% vs 4%).

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Common adverse reactions in the hypertriglyceridemia trials (incidence >1% more frequent than placebo): arthralgia (2% vs 1%) and oropharyngeal pain (1% vs 0.3%).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Adverse events may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Patients receiving VASCEPA and concomitant anticoagulants and/or anti-platelet agents should be monitored for bleeding.

**Use of Non-GAAP Adjusted Financial Information** 

Included in this press release are non-GAAP adjusted financial information as defined by U.S. Securities and Exchange Commission Regulation G. The GAAP financial measure is most directly comparable to each non-GAAP adjusted financial measure used or discussed, and a reconciliation of the differences between each non-GAAP adjusted financial measure and the comparable GAAP financial measure, is included in this press release after the condensed consolidated financial statements.

Non-GAAP adjusted net (loss) income was derived by taking GAAP net loss and adjusting it for non-cash stock-based compensation expense, restructuring expense and other one-time expenses. Management uses these non-GAAP adjusted financial measures for internal reporting and forecasting purposes, when publicly providing its business outlook, to evaluate the company's performance and to evaluate and compensate the company's executives. The company has provided these non-GAAP financial measures in addition to GAAP financial results because it believes that these non-GAAP adjusted financial measures provide investors with a better understanding of the company's historical results from its core business operations.

While management believes that these non-GAAP adjusted financial measures provide useful supplemental information to investors regarding the underlying performance of the company's business operations, investors are reminded to consider these non-GAAP measures in addition to, and not as a substitute for, financial performance measures prepared in accordance with GAAP. Non-GAAP measures have limitations in that they do not reflect all the amounts associated with the company's results of operations as determined in accordance with GAAP. In addition, it should be noted that these non-GAAP financial measures may be different from non-GAAP measures used by other companies, and management may utilize other measures to illustrate performance in the future.

**Forward-Looking Statements** 

This press release contains forward-looking statements which are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, including beliefs about Amarin's key achievements in 2025 and the potential impact and outlook for achievements in 2026 and beyond; Amarin's 2026 financial outlook and cash position; Amarin's overall efforts to expand access and reimbursement to VAZKEPA across global markets; expectations regarding potential strategic collaboration and licensing agreements with third parties, including our ability to attract additional collaborators, as well as our plans and strategies for entering into potential strategic

------

collaboration and licensing agreements and the overall potential and future success of VASCEPA/VAZKEPA and Amarin that are based on the beliefs and assumptions and information currently available to Amarin.
