AMGEN ANNOUNCES ADDITIONAL $300 MILLION U.S. MANUFACTURING INVESTMENT, TOTALING NEARLY $2 BILLION OVER THE LAST YEAR

Investment Strengthens American Manufacturing, Supply Chain Resilience and Next-Generation Technology

THOUSAND OAKS, Calif., May 4, 2026 /PRNewswire/ -- Amgen (NASDAQ: AMGN) today announced plans to invest an additional $300 million in its U.S. manufacturing network to further advance U.S.-based production capacity, enhance next-generation technologies and support a reliable supply of medicines for patients.

"Amgen has been a leader in U.S. biomanufacturing for decades, and this expansion reflects our continued commitment to American manufacturing," said Robert A. Bradway, chairman and chief executive officer at Amgen. "By growing our operations in Puerto Rico, we are ensuring patients have access to the medicines they need, investing in the long-term strength of our domestic supply chain and supporting American jobs."

Amgen's expansion of its biologics manufacturing facility in Puerto Rico will strengthen existing advanced manufacturing roles, support workforce development across the region and generate hundreds of construction jobs. Established in 1992, the company's Juncos site is one of the largest and most advanced biomanufacturing facilities in the world, producing biologic medicines distributed to more than 60 countries.

Amgen's latest investment builds on its broader U.S. manufacturing expansion strategy. Over the past year, the company has announced planned investments of $650 million in Puerto Rico, $900 million in Ohio and $600 million in a science and innovation center in California. In addition, Amgen has invested more than $1.5 billion in North Carolina.

"This investment confirms that the policies we have implemented are working. Puerto Rico has more than 60 years of excellence in the biopharmaceutical sector, supported by a highly skilled workforce and world‑class infrastructure, and Amgen knows this better than anyone," said Puerto Rico Governor Jenniffer González Colón. "We will continue working to make Puerto Rico the number one destination for advanced manufacturing in the United States."

"Amgen's additional $300 million commitment in Juncos is a powerful signal that the future of American biomanufacturing is being built here. Combined with the $650 million previously announced, this represents nearly $1 billion in confidence in our workforce, our capabilities and our ability to produce life‑saving medicines," said Sebastián Negrón Reichard, Puerto Rico Secretary of the Department of Economic Development and Commerce. "This is the result of our commitment to building a pro‑business jurisdiction where world‑class companies like Amgen can grow, invest and thrive."

Amgen's long-standing commitment to U.S. innovation and state-of-the-art operations is reflected in more than $40 billion invested in manufacturing and research and development since the enactment of the Tax Cuts and Jobs Act (TCJA) of 2017. Pro-growth tax policies in TCJA, extended and reinforced by the One Big Beautiful Bill Act of 2025, support the company's ability to invest in domestic science and manufacturing.

Amgen Forward-Looking Statements
This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including any statements on the outcome, benefits and synergies of collaborations, or potential collaborations, with any other company (including BeOne Medicines Ltd.), the performance of Otezla® (apremilast), our acquisitions of ChemoCentryx, Inc., Dark Blue Therapeutics, Ltd. or Horizon Therapeutics plc (including the prospective performance and outlook of Horizon's business, performance and opportunities, and any potential strategic benefits, synergies or opportunities expected as a result of such acquisition), as well as estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes, effects of pandemics or other widespread health problems on our business, outcomes, progress, and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including our most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. 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, and may result in unanticipated costs, delays or failures to realize the benefits of the transactions. 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. The effects of global climate change and related natural disasters could negatively affect our business and operations. Global economic conditions may magnify certain risks that affect our business. Our business performance could affect or limit the ability of our Board of Directors to declare a dividend or our ability to pay a dividend or repurchase our common stock. We may not be able to access the capital and credit markets on terms that are favorable to us, or at all.
