Total Revenue Increased Led by Higher International Sales

Generated Positive Cash Flow and Reiterates Expectation for Full Year Positive Cash Flow

Recently Updated Industry Guidelines Expand Global Medical Society Endorsements Supporting the Use of Icosapent Ethyl (IPE) in Contemporary Lipid and Cardiovascular Risk Management

DUBLIN, Ireland and BRIDGEWATER, N.J., April 29, 2026 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ: AMRN), a company committed to advancing the science of cardiovascular disease worldwide, today announced financial results for the first quarter ended March 31, 2026 (Q1 2026).

“Our results for Q1 2026 reflected the early yet measurable progress generated by our refined global business model which we adopted in mid-2025,” said Aaron Berg, President and Chief Executive Officer.

“The promise of our fully-partnered international commercial strategy – anchored by our European-focused exclusive licensing and supply agreement with Recordati S.p.A. (Recordati) - was reflected in higher European product revenue in Q1 2026 compared to Q4 2025. This consecutive quarterly growth was attributable to strong in-market demand for VAZKEPA^® (icosapent ethyl) and the priority assigned by Recordati to expand the commercial reach for this proven therapy. While acknowledging that European sales will vary quarter to quarter, especially in the early days of this new partnership, these initial results are encouraging. Recordati has commenced commercial efforts of VAZKEPA in 10 countries, including a Q4 2025 launch in Italy, and plans to expand its distribution across Europe over the next several years. We are also seeing good growth from our active commercial partners outside of Europe.”

“Our U.S. franchise continues to demonstrate remarkable resilience, where we have maintained our leading market share for VASCEPA^® more than five years since the introduction of generics. Industry prescription data for Q1 2026 showed an overall increase in the icosapent ethyl (IPE) market while VASCEPA-branded prescriptions rose by 17% compared to Q1 2025. We expect that volumes will remain stable throughout 2026. Our streamlined U.S. operation remains an efficient, cash generating engine for our Company.” 

He continued, “We are encouraged by the 2026 American College of Cardiology (ACC) / American Heart Association (AHA)/Multisociety Dyslipidemia Guideline Update from March of this year that supports the broader clinical role of IPE in reducing cardiovascular (CV) risk in statin-treated patients with elevated triglycerides. These guidelines shift CV care toward early, lifelong prevention and a more comprehensive risk approach beyond just lowering LDL cholesterol. In recognizing that high triglyceride levels contribute to CV events in many patients, this framework underscores the need for additional therapies beyond statins to address this care gap. This evolutionary perspective on CV risk management is timely and strengthens our position to address the burden of CV disease in patients and across the healthcare ecosystem.”

Mr. Berg concluded, “We have created a new version of Amarin – focused, leaner, and both financially and operationally stronger than at any time in our recent history. The growth initiatives we have undertaken and building industry tailwinds increasingly focused on the needs of patients with elevated triglycerides have positioned us well for 2026. Our team is executing with focus and discipline to achieve our objectives and deliver shareholder value, while continuing to work closely with Barclay’s, our exclusive financial advisor, in exploring additional potential pathways to further enhance shareholder value. While there is still work to be done, we look forward to our future with confidence.”

Peter Fishman, Amarin’s Chief Financial Officer, said, “We are encouraged by our Q1 2026 performance under our new business model. We achieved higher total revenue, led by growth from our partners, and a continued decline in our operating expenses, both of which led to significantly narrowed losses compared to the same period last year. We remain on track to realize the approximately $70 million in cost savings and have incurred nearly all of the associated restructuring costs. Finally, we generated positive cash flow for the second consecutive quarter and continue to expect to be cash flow positive for full year 2026.”

Total Net Revenue	$45.1		$42.0		7%
NM - Not Meaningful

Total Net Revenue: Increased $3.1 million, or 7%. U.S. sales of VASCEPA were consistent with the prior year period, benefitting from an increase in volume related to the regaining of exclusive status with a large national pharmacy benefit manager (PBM) beginning in Q3 2025. A slight decline in European revenue was attributable to moving to a partnered sales model in the second half of 2025, a transition that had yet to take effect in Q1 2025. Quarter-to-quarter European sales comparisons that reflect the partnership model with Recordati will commence in Q3 2026. Licensing and royalty revenue increased by 84% due to higher in-market sales generated by our international commercial sales partners.

Total Operating Expenses: Decreased $12.8 million, or 31%, primarily due to the impact of the June 2025 Global Restructuring that produced declines in Selling, General, and Administrative expenses (SG&A). Excluding the restructuring charge of $3.3 million (see discussion below), Q1 2026 total operating expenses were $25.8 million, representing a decline of 38%.

COGS: Increased $10.5 million, or 62%, reflecting increased product volumes to satisfy demand associated with our exclusive PBM relationship that took effect July 1, 2025 and shipments to ROW partners that did not exist in last year’s first quarter.

SG&A: Decreased $15.5 million, or 42%, primarily due to a reduction in costs pursuant to the Global Restructuring and other cost optimization initiatives, slightly offset by litigation settlements.

R&D: Consistent with the prior year period.

Restructuring: The Company recognized $3.3 million in Q1 2026 related to the continued implementation of the Global Restructuring associated with the execution of the Recordati Licensing Agreement announced in June 2025. The Company has incurred a total of $ 39.6 million of restructuring charges through Q1 2026, with the remaining nominal charges expected to be realized in Q2 2026.

Comparisons to Q1 2025, unless otherwise stated

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 Indications and Limitation of Use
VASCEPA is indicated:  

• 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 established cardiovascular disease or diabetes mellitus and two or more additional risk factors for cardiovascular disease.  
• 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

• VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.
• 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. 
• 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. 
• 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. 
• 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%). 
• Common adverse reactions in the hypertriglyceridemia trials (incidence >1% more frequent than placebo): arthralgia (2% vs 1%) and oropharyngeal pain (1% vs 0.3%). 
• Adverse events may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088. 
• Patients receiving VASCEPA and concomitant anticoagulants and/or anti-platelet agents should be monitored for bleeding.
