THOUSAND OAKS, Calif., May 1, 2025 /PRNewswire/ -- Amgen (NASDAQ:AMGN) today announced financial results for the first quarter of 2025. "Demand for our products was strong globally in the first quarter. Ongoing new product launches and successful Phase 3 trial results for several products make us feel confident in our long-term growth prospects," said Robert A. Bradway, chairman and chief executive officer. Key results include: For the first quarter, total revenues increased 9% to $8.1 billion in comparison to the first quarter of 2024. Product sales grew 11%, primarily driven by 14% volume growth, partially offset by 6% lower net selling price. U.S. sales grew 14%. Fourteen products delivered at least double-digit sales growth in the first quarter, including Repatha® (evolocumab), BLINCYTO® (blinatumomab), TEZSPIRE® (tezepelumab-ekko), EVENITY® (romosozumab-aqqg), TAVNEOS® (avacopan) and UPLIZNA® (inebilizumab-cdon). Our launch of IMDELLTRA ® (tarlatamab-dlle) generated $81 million of sales in the quarter and the Phase 3 confirmatory study demonstrated improved overall survival compared to chemotherapy. IMDELLTRA ® launched in Japan in April 2025. GAAP earnings per share (EPS) were $3.20 for the first quarter of 2025 compared with a GAAP loss per share of $0.21 for the first quarter of 2024, resulting from an unrealized gain on our BeiGene, Ltd. equity investment during the first quarter of 2025 compared to an unrealized loss during the prior year period, partially offset by an Otezla® intangible asset impairment charge of $800 million recorded during the first quarter of 2025. GAAP operating income increased from $1.0 billion to $1.2 billion, and GAAP operating margin increased 1.1 percentage points to 15.0%. Non-GAAP EPS increased 24% from $3.96 to $4.90, driven by higher revenues, partially offset by higher operating expenses. Non-GAAP operating income increased from $3.1 billion to $3.6 billion and non-GAAP operating margin increased 2.5 percentage points to 45.7%. The Company generated $1.0 billion of free cash flow in the first quarter of 2025 versus $0.5 billion in the first quarter of 2024. This increase reflects an $800 million tax deposit made in the first quarter of 2024 and current quarter business performance, partially offset by timing of working capital items and higher capital expenditures. References in this release to "non-GAAP" measures, measures presented "on a non-GAAP basis," and "free cash flow" (computed by subtracting capital expenditures from operating cash flow) refer to non-GAAP financial measures. Adjustments to the most directly comparable GAAP financial measures and other items are presented in the attached reconciliations. Refer to Non-GAAP Financial Measures below for further discussion.

Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise. No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Our results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments involving current and future products, sales growth of recently launched products, competition from other products including biosimilars, difficulties or delays in manufacturing our products and global economic conditions, including those resulting from geopolitical relations and government actions. In addition, sales of our products are affected by pricing pressure, political and public scrutiny and reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or manufacturing problems with our products, including our devices, after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. In addition, our business may be impacted by the adoption of new tax legislation or exposure to additional tax liabilities. Further, while we routinely obtain patents for our products and technology, the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors, or we may fail to prevail in present and future intellectual property litigation. We perform a substantial amount of our commercial manufacturing activities at a few key facilities, including in Puerto Rico, and also depend on third parties for a portion of our manufacturing activities, and limits on supply may constrain sales of certain of our current products and product candidate development. An outbreak of disease or similar public health threat, and the public and governmental effort to mitigate against the spread of such disease, could have a significant adverse effect on the supply of materials for our manufacturing activities, the distribution of our products, the commercialization of our product candidates, and our clinical trial operations, and any such events may have a material adverse effect on our product development, product sales, business and results of operations. We rely on collaborations with third parties for the development of some of our product candidates and for the commercialization and sales of some of our commercial products. In addition, we compete with other companies with respect to many of our marketed products as well as for the discovery and development of new products. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers. Certain of our distributors, customers and payers have substantial purchasing leverage in their dealings with us. The discovery of significant problems with a product similar to one of our products that implicate an entire class of products could have a material adverse effect on sales of the affected products and on our business and results of operations. Our efforts to collaborate with or acquire other companies, products or technology, and to integrate the operations of companies or to support the products or technology we have acquired, may not be successful. There can be no guarantee that we will be able to realize any of the strategic benefits, synergies or opportunities arising from the Horizon acquisition, and such benefits, synergies or opportunities may take longer to realize than expected. We may not be able to successfully integrate Horizon, and such integration may take longer, be more difficult or cost more than expected. A breakdown, cyberattack or information security breach of our information technology systems could compromise the confidentiality, integrity and availability of our systems and our data. Our stock price is volatile and may be affected by a number of events. Our business and operations may be negatively affected by the failure, or perceived failure, of achieving our sustainability objectives.

Ad hoc announcement pursuant to Art. 53 LR Allschwil, Switzerland – April 30, 2025Idorsia Ltd (SIX: IDIA) today announced its financial results for the first quarter of 2025. Business highlights Q1 2025 QUVIVIQ™ (daridorexant): Strong performance and accelerating sales in Q1 2025 with total Idorsia-led net sales of CHF 25 m.QUVIVIQ EUCAN: Demand grew by 50% from Q4 2024 to Q1 2025, strongly driven by reimbursed markets. Overall, more than 10 million nights of sleep prescribed in Q1 2025.Daridorexant: Positive data with daridorexant in patients with chronic insomnia and nocturia published in the Journal of Sleep Research and assessing the transition from night to day published in Sleep Medicine.TRYVIO™ (aprocitentan): REMS requirement removed by US FDA.Aprocitentan: Effect of reducing blood pressure and proteinuria in Black patients with resistant hypertension published in HypertensionRestructured convertible bond debt: Tailored approach to remove large debt overhang.New funding: Bondholders to provide CHF 150 m new money facility.Viatris collaboration: Updated agreement removed significant cash requirement for 2025. Financial highlights Net revenue Q1 2025 of CHF 59 m.US GAAP operating expenses Q1 2025 of CHF 5 m (income) were positively impacted by a one-off gain from the amendment of the Viatris deal with non-GAAP operating expenses Q1 2025 of CHF 78 m.US GAAP operating income Q1 2025 of CHF 67 m and non-GAAP operating loss of CHF 17 m. Guidance for 2025 – unforeseen events excluded QUVIVIQ net sales of around CHF 110 m.SG&A expenses of around CHF 210 m, R&D expenses of around CHF 100 m, leading to non-GAAP operating expenses of around CHF 325 m.US GAAP loss for global business of around CHF 125 m. André C. Muller, Chief Executive Officer of Idorsia, commented:“Beyond the transformation of Idorsia’s financial situation, we made significant progress on multiple fronts in the first quarter. QUVIVIQ is taking off in Europe with a particularly impressive performance in France following the commercial partnership to call on GPs initiated in October 2024; we hope Germany will follow suit, as a similar partnership will kick-in from April 2025. In the US, we have implemented a focused commercialization approach for QUVIVIQ to maintain sales until the potential descheduling of the dual orexin receptor antagonist (DORA) class can be achieved. We received great news from the FDA, with the removal of the REMS requirement for TRYVIO allowing a shift toward broad product availability in retail pharmacies. This, together with the early positive prescribing experience in leading US hypertension centers of excellence gives us confidence of the potential of our antihypertensive drug. Lastly, we streamlined the R&D organization to invest in our promising refocused pipeline. All these achievements put us on a solid path to reach our 2025 goals.” Financial results US GAAP results First Quarterin CHF millions, except EPS (CHF) and number of shares (millions) 20252024Net revenue 5910Operating expenses 520Operating income 6731Net income 6330Basic EPS 0.330.17Basic weighted average number of shares 188.9179.1Diluted EPS 0.230.13Diluted weighted average number of shares 270.8233.3 Net revenue of CHF 59 m in Q1 2025 resulted from QUVIVIQ product sales (CHF 25 m), product sales to partners (CHF 1 m), and contract revenues (CHF 32 m), comprising a one-off exclusivity fee of CHF 32 m paid by an undisclosed party in relation to a potential aprocitentan deal, and non-cash revenue related to the R-Bridge royalty monetization agreement of CHF 1 m. This compares to net revenue of CHF 10 m in Q1 2024 from QUVIVIQ product sales. US GAAP operating expenses of CHF 5 m (income) in Q1 2025 and CHF 20 m (income) in Q1 2024 were impacted by a one-off gain of CHF 90 m (Viatris deal amendment) in 2025 and CHF 125 m (Viatris deal) in 2024, respectively. Excluding these one-off gains, US GAAP operating expenses at Q1 2025 decreased by CHF 20 m, mainly driven by R&D expenses of CHF 27 m decreasing by CHF 6 m compared to Q1 2024 (CHF 33 m), and SG&A expenses of CHF 54 m decreasing by CHF 14 m compared to Q1 2024 (CHF 68 m). US GAAP net income in Q1 2025 of CHF 63 m (CHF 27 m net loss excluding Viatris deal amendment) and CHF 30 m in Q1 2024 (CHF 95 m net loss excluding Viatris deal). Excluding these one-offs, the reduced net loss in Q1 2025 was primarily due to lower operating expenses from cost savings through the effective restructuring efforts announced in November 2024 and higher revenue. The US GAAP net income resulted in a basic net income per share of CHF 0.33 (diluted net income per share of CHF 0.23) in Q1 2025, compared to a basic net income per share of CHF 0.17 (diluted net income per share of CHF 0.13) in Q1 2024.

Idorsia believes that these non-GAAP financial measurements more accurately reflect the underlying business performance and therefore provide useful supplementary information to investors. These non-GAAP measures are reported in addition to, not as a substitute for, US GAAP financial performance. Non-GAAP net loss in Q1 2025 amounted to CHF 25 m; the difference versus US GAAP net income was mainly driven by the one-off gain from the amendment of the Viatris Deal (CHF 90 m). The non-GAAP net loss resulted in a net loss per share of CHF 0.13 (basic and diluted) in Q1 2025, compared to a net loss per share of CHF 0.48 (basic and diluted) in Q1 2024. Viatris collaborationIn March 2024, Idorsia entered into a global research and development collaboration with Viatris, for the global development and commercialization rights to selatogrel and cenerimod. Idorsia received an upfront payment of USD 350 million (CHF 308 million) with Idorsia obligated to contribute USD 200 million for the development of selatogrel and cenerimod. Idorsia is entitled to potential development and regulatory milestone payments, and certain contingent payments of additional sales milestone payments and tiered royalties in the mid-single to low-double digit percentages on annual net sales. In February 2025, Idorsia reached an agreement with Viatris to update the terms of the collaboration. In exchange for a USD 100 million reduction to Idorsia’s contribution to the development costs due in 2025, Idorsia has agreed to a USD 250 million reduction in future potential regulatory and sales milestone payments, and an expansion of territorial rights to Viatris for cenerimod. The agreed royalties on future sales remain unchanged. Under the updated terms, Idorsia's contribution for the development of selatogrel and cenerimod is reduced to USD 100 million with no commitment in 2025. Idorsia has contributed USD 73 million in 2024 for the performance of development services, and the remaining USD 27 million will be paid in 2026. Restructured convertible bond debt and new funding securedOn February 26, 2025, Idorsia announced that it has reached an agreement with more than two-thirds of the holders of its outstanding convertible bond debt on the main terms of a holistic restructuring of the bonds and a CHF 150 million new money facility, to alleviate the short- to mid-term debt overhang of CHF 800 million while retaining upside potential of key assets beyond the value of the debt. As part of the holistic restructuring Idorsia will issue up to 27.5 million shares and up to 25.5 million warrants. When complete, the tailored solution secures future operations of Idorsia into 2026. More information can be found in the dedicated press release. Capital increaseIn connection with the holistic restructuring of the convertible bond debt and raising of additional funds, 35 million registered shares with a nominal value of CHF 0.05 each were created out of capital band and were listed on March 4, 2025. Financial guidance for 2025As previously announced, for the Idorsia-led portfolio in 2025, the company expects a continued acceleration of QUVIVIQ with net sales of around CHF 110 million, COGS of around CHF 15 million, SG&A expenses of around CHF 210 million, and R&D expense of around CHF 100 million, leading to non-GAAP operating expenses of around CHF 325 million. This performance would result in an Idorsia-led business non-GAAP operating loss of around CHF 215 million and US-GAAP operating loss of around CHF 260 million. The company expects US-GAAP EBIT for the partnered business of around CHF 135 million – updated to reflect the positive impact of the one-off exclusivity fee paid by an undisclosed party in Q4 2024 but recognized in Q1 2025 – and mainly driven by the amended deal with Viatris. This would result in a US-GAAP loss for the global business of around CHF 125 million. All amounts exclude unforeseen events and potential revenue related to additional business development activities. Arno Groenewoud, Chief Financial Officer, commented:“The updated agreement with Viatris, and the convertible debt restructuring, together with the new money facility agreed with our bondholders, has significantly changed the financial situation of Idorsia. That said, there are still several steps to implement in order to realize what was agreed. The restructuring of the bonds is moving forward with the first step approved by the court, allowing us to proceed to the next bondholder meetings. We are also making progress with putting the new money facility in place. The excellent uplift with QUVIVIQ in Europe and the tight cost-control means we are well on track with our financial performance targets.” Liquidity and indebtednessAt the end of the first quarter of 2025, Idorsia’s liquidity amounted to CHF 51 million.

In France, QUVIVIQ is reimbursed for moderate and severe chronic insomnia patients after, or as an alternative to, cognitive behavioral therapy for insomnia. The outstanding launch in France is driven by a combination of co-promotion with Menarini reflected by a new-to-brand share growing from 1.1% in September 2024 to 9.3% in January 2025 in the general practitioner (GP) segment, and a strong positioning to specialists in retail and hospital settings reflected by a solid new-to-brand share evolution from 9.7% in September 2024 to 14.4% in January 2025 in the psychiatrist segment. In Germany, QUVIVIQ was launched in November 2022 and is the only sleep medication in Germany that can be prescribed for long-term treatment of chronic insomnia. The progress made in Germany is reflected by the performance of QUVIVIQ on the market, with demand increasing by 20% quarter on quarter. In February 2025, Idorsia successfully concluded negotiations for the reimbursement price in Germany. Idorsia is expanding its commercial reach from specialist prescribers to GPs through a commercial partnership with Berlin-Chemie (a wholly owned subsidiary of the Menarini Group), which started in April 2025. In the UK, QUVIVIQ is recommended as first-line pharmaceutical treatment for patients with chronic insomnia, after, or as an alternative to, cognitive behavioral therapy for insomnia (CBT-I). QUVIVIQ was launched in October 2023 at NICE approval. The priority in the UK in 2024 was to secure regional access, and the team has achieved reimbursement throughout 85% of the UK, as well as raising awareness of QUVIVIQ among general practitioners. Increased access and awareness have started to translate into strong demand in the UK which grew by 48% from Q4 2024 to Q1 2025. In Canada, after being approved in April 2023, QUVIVIQ was launched in November 2023 to the private market, representing 55% of the Canadian insomnia market. To date, 85% of private Canadian lives are covered. The focus is now on public payers; the company submitted public reimbursement dossiers and expects decisions by the end of 2025. QUVIVIQ demand in Canada grew by 25% from Q4 2024 to Q1 2025. Austria will soon become the fourth EUCAN country to grant public reimbursement to QUVIVIQ, starting from June 1, 2025. This is a significant achievement in a country that has strict reimbursement rules and underpins the value QUVIVIQ brings to patients, physicians and the healthcare system. In Italy, QUVIVIQ is now officially available for all prescribers, following its publication in the Official Gazette in mid-March 2025, this includes GPs who represent nearly 80% of the total insomnia market. In Switzerland, Spain, and Sweden, where we are still negotiating for reimbursement, launches have been very successful despite the out-of-pocket costs for patients, particularly in Switzerland where we see a strong demand. Benjamin Limal, President of Europe and Canada region, commented:“Demand has grown by an impressive 50% quarter on quarter, mainly driven by reimbursed markets. Across Europe and Canada, more than 10 million nights of sleep have been prescribed in the first quarter of 2025. Recent successes in access and pricing, notably in Austria and Germany, reinforce our confidence for continued growth moving forward. QUVIVIQ has been strongly adopted by specialists and more and more general practitioners start prescribing QUVIVIQ due to our increased efforts with recent partnerships for the GP market.” For more information about QUVIVIQ in the EU, see the Summary of Product Characteristics.

United States ProductMechanism of actionIndicationCommercially available sinceDual orexin receptor antagonistTreatment of adult patients with insomnia, characterized by difficulties with sleep onset and/or sleep maintenanceMay 2022 QUVIVIQ® (daridorexant) net sales in the first quarter of 2025 amounted to CHF 5.9 million in the US, compared to CHF 6.5 million in the first quarter of 2024. As of the end of the first quarter of 2025, more than 180,000 patients have been treated with QUVIVIQ since launch in the US, over 600,000 prescriptions have been dispensed, and the product has been prescribed by more than 50,000 healthcare professionals. Michael Moye, President and General Manager of Idorsia US, commented:“We have implemented a streamlined, focused, and more cost-efficient commercialization approach for QUVIVIQ to maintain sales until the potential descheduling of the dual orexin receptor antagonist (DORA) class can be achieved. Our commercialization partner, Syneos Health, is fully operational and executing a highly targeted digital marketing plan supporting 20 virtual sales reps. Syneos is now also executing educational programming and market access activities in support of the virtual representatives. We are seeing early, positive prescribing results in key customer areas.” For more information about QUVIVIQ in the US, see the Full Prescribing Information (PI and Medication Guide). ProductMechanism of actionIndicationCommercially available sinceDual endothelin receptor antagonistTreatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adult patients who are not adequately controlled on other drugsOctober 2024 On March 19, 2024, the US Food and Drug Administration (FDA) approved TRYVIO™ (aprocitentan) for the treatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adult patients who are not adequately controlled on other drugs. Lowering blood pressure reduces the risk of fatal and non-fatal cardiovascular events, primarily strokes and myocardial infarctions. The recommended dosage of TRYVIO is 12.5 mg orally once daily, with or without food. Following the approval, the US team rapidly established the positioning, branding, websites, materials, training and educational platforms, and field sales force and MSL coverage plans. TRYVIO was made available for prescription in October 2024 via Walgreens Specialty Pharmacy. There is ongoing engagement with hypertension experts at major cardiovascular and nephrology congresses and encouraging discussions with payors. In March 2025, the US FDA fully released TRYVIO from its REMS (Risk Evaluation and Mitigation Strategy) requirement to minimize the burden on the healthcare delivery system of complying with the REMS. The US FDA has determined that a REMS is no longer necessary to ensure the benefits of TRYVIO outweigh the risk of embryo-fetal toxicity and that labeling is sufficient for conveying the safety information. As a result, a rapid transition from specialty pharmacy to a wide retail pharmacy distribution model is underway. Funding for a field sales force and promotional activities continues to be dependent on a partnership deal. Michael concluded:“Early prescribing experience in leading US hypertension centers of excellence has been very positive, with prescribers confirming that they are seeing blood pressure reductions, safety and tolerability consistent with the Phase 3 study. The REMS removal and shift toward broad product availability in retail pharmacies has profoundly improved the potential of TRYVIO to reach millions of patients struggling with their hypertension on existing medication regimens.” For more information see the Full Prescribing Information including BOXED Warning (PI and Medication Guide). Research & DevelopmentOur drug discovery engine has produced innovative drugs with the potential to transform the treatment paradigm in multiple therapeutic areas, including CNS, cardiovascular, and immunological disorders, as well as orphan diseases. The company also has a vaccine platform for the discovery and development of glycoconjugate vaccines to prevent infection. The company has focused its drug discovery efforts, reducing the number of active projects in research and development and preparing some for out-licensing. The prioritization has resulted in a portfolio of assets where Idorsia intends to develop to the next inflection point before partnering, or when feasible and appropriate, developing further ourselves. The company expects new lucerastat data from a kidney biopsy sub-study (to the ongoing Phase 3 open-label extension study) in the second quarter of 2025, with further discussions on the regulatory pathway to follow. The results from a Phase 1 study of our Clostridium difficile infection vaccine are also expected in the coming months. The company will need to further prioritize activities in order to reduce costs and the decisions on which assets to advance will be taken based on the data when available and the results of ongoing out-licensing discussions for early-stage assets. In March 2025, “A randomized cross-over trial of daridorexant for the treatment of chronic insomnia and nocturia” was published in the Journal of Sleep Research. The new data provides evidence of the benefit of daridorexant, at a daily dose of 50 mg, in patients aged >=55 years with chronic insomnia and comorbid nocturia, with efficacy data on symptoms of both conditions, improvement in daytime functioning, and a good safety and tolerability profile. In April 2025, the “Effect of daridorexant on nighttime wakefulness and next-morning sleepiness: assessing the transition from night to day in insomnia disorder” was published in Sleep Medicine. The analysis of the Phase 3 data provides evidence that daridorexant reduces wakefulness throughout the entire night, while decreasing morning sleepiness and improving daytime functioning and alertness in patients with chronic insomnia disorder. Idorsia-led portfolioThe company will develop each asset to the next inflection point or seek a partner.

We seek suitable external project partners to maximize the value of internal innovation. On March 19, 2024, the US Food and Drug Administration (FDA) approved TRYVIO™ (aprocitentan) for the treatment of hypertension in combination with other antihypertensive drugs, to lower blood pressure in adult patients who are not adequately controlled on other drugs. See the commercial operations section above. On June 27, 2024, the European Commission (EC) approved JERAYGO™ (aprocitentan) for the treatment of resistant hypertension in adult patients in combination with at least three antihypertensive medicinal products. The recommended dose is 12.5 mg orally once daily. The dose can be increased to 25 mg once daily for patients tolerating the 12.5 mg dose and in need of tighter blood pressure (BP) control. For more information about JERAYGO in the EU, see the Summary of Product Characteristics. Aprocitentan is an innovative and highly differentiated drug, commercially available in the US and approved in Europe and UK for the millions of patients who are unable to bring their hypertension under control with existing medications. As the first drug to target the endothelin pathway in systemic hypertension, aprocitentan has blockbuster potential in uncontrolled hypertension, particularly for difficult to treat patients with chronic kidney disease and hypertension, and further potential beyond hypertension. The priority remains to partner aprocitentan, having been released from the exclusivity constraint with the undisclosed party, the company will resume discussions with alternative potential partners that recognize the value of aprocitentan. In April 2025, "Aprocitentan for Blood Pressure Reduction in Black Patients” was published in Hypertension. The publication reports preplanned analyses of the efficacy, tolerability and safety of aprocitentan in the subgroup of African American patients enrolled in the Phase 3 PRECISION study in patients with confirmed resistant hypertension. Aprocitentan, when added to a combination of at least three antihypertensive drugs (four in more than 50% of patients), produced clinically meaningful and sustained blood pressure reductions.

iStock, Besiki Kavtaradze It’s been a fraught road for the proposed merger between Acelyrin and Alumis, with Tang Capital’s Concentra Biosciences in February threatening to upend the deal with a proposed $3-per-share acquisition of Acelyrin. In February, two California-based biotechs, Acelyrin and Alumis, announced that they would merge. Now, England-based Trium Capital, a significant Acelyrin shareholder, will vote against the planned merger, the investment firm announced in a letter dated April 28th. Trium contends that Acelyrin has better strategic options than the merger, which it says undervalues the biotech. “It is unclear to us why Acelyrin should accept a consideration that is so substantially less than its cash value,” the letter reads. Acelyrin’s shareholders “should not have to accept” this discount. The investment firm also took aim at Acelyrin’s board of directors. “The board attempts to justify the merger by contrasting the merger with Acelyrin’s supposedly meagre standalone prospects” and by arguing that the biotech would continue to trade poorly, Trium said. “This is a false choice,” the investor continued, noting that the recent buy offer from Tang Capital’s Concentra Biosciences proves that the biotech could be worth much more than the Alumis deal. Concentra in late February came in between the planned merger, offering to scoop up Acelyrin for $3 per share, which would total about $300 million, versus its trade price of $2.17 at the previous day’s market close. Concentra also tacked on a contingent value right to its offer, which would have given Acelyrin’s shareholders 80% of net proceeds from out-licensing deals or asset sales. Acelyrin not only rebuffed the offer a few days later—arguing that Concentra’s proposal “is not reasonably expected to result in a superior” deal to the merger—but the biotech also considered Concentra a hostile entity. In mid-March, Acelyrin adopted what is called a poison-pill defense , ensuring that its stockholders would be able to purchase additional shares at a steep discount in the event that any investor tries to stage a takeover. Concentra’s proposal “is over 50% higher than where Acelyrin traded prior to announcement of the Alumis merger,” Trium noted. “Acelyrin will have levers to deliver value to shareholders in the absence [of] a transaction.” One such lever, which Trium also says is preferable to the merger, is to wind down Acelyrin’s operations, liquidate its assets and return them to shareholders. Such a move, according to the investor, “provides certainty of value well above the value from any of the offers received thus far.” Acelyrin and Alumis inked their all-stock merger agreement in February, under which terms Alumis will absorb Acelyrin. The combined entity will be headed by Alumis’ current executive leadership. Acelyrin stockholders will own 45% of the post-merger company. Acelyrin’s stockholder meeting is scheduled on May 13 , at which time shareholders will vote on the proposed merger. According to an SEC filing , the new company would have about $737 million in cash to take it into 2027, beyond several expected data readouts. That includes a current Alumis Phase III trial for plaque psoriasis and a Phase IIb trial in systemic lupus erythematosus.
