As of June 2026, the Amgen New Albany biomanufacturing plant, a final product assembly and packaging operation in central Ohio first announced in 2021, has grown from a single newly opened facility into the anchor of the largest life sciences manufacturing expansion in Ohio history. The original plant opened on February 26, 2024, a roughly 300,000 square foot site that Amgen called the most advanced facility in its production network, debuting with about 400 full time employees, an automated storage and retrieval system and a fleet of automated guided vehicles. Barely a year after the ribbon cutting, the project shifted into a far larger phase that has redefined the scale of Amgen’s commitment to the Columbus region.

Amgen Commits $900 Million to a Second New Albany Facility

On April 25, 2025, Amgen announced a $900 million expansion in New Albany, with public filings citing a committed minimum of at least $822 million. The money funds a new 418,000 square foot building beside the existing plant on land Amgen already owns, divided between roughly $614 million in construction and $208 million in machinery and equipment. The expansion is expected to add 350 jobs while retaining the 400 already on site, pushing total employment toward 750 and lifting Amgen’s overall central Ohio investment past $1.4 billion. Chairman and CEO Robert Bradway framed the decision as part of the company’s wider drive to expand United States manufacturing, pointing to Ohio’s workforce, business climate and location.

What the Expansion Means for Ohio’s Biomanufacturing Sector

The second build reinforces a regional life sciences surge that economic developers have tracked closely. One Columbus reported more than 2,500 newly announced life sciences jobs across the region between the first quarter of 2021 and the third quarter of 2025, and has linked Amgen’s growth to a new Biomanufacturing Workforce Center of Excellence and technician training with Columbus State University. That momentum is now drawing other global drugmakers south of Columbus. Lonza, the world’s largest contract development and manufacturing organization, secured a 20 year Ohio Job Creation Tax Credit on June 29, 2026, for a proposed $1 billion biotech plant in Clermont County that could create 650 jobs, a project that points to the same Cincinnati to Columbus corridor Amgen helped establish.

Amgen New Albany Completion Date and Sustainability Goals

Construction of the expansion facility is expected to be completed in 2027, with operations also scheduled to begin that year. Amgen has paired the build with an environmental agenda, adding solar arrays and low emission systems as it works toward a carbon neutrality goal tied to the same 2027 horizon. The milestones to watch next are structural completion of the new building, the equipment installation phase, and the hiring ramp toward the 350 new positions, all of which will determine whether the site meets its 2027 operational target.

Reported 13th November 2021: Construction has begun on an Amgen Biomanufacturing plant in New Albany, Central Ohio. The facility will be utilized as a final product assembly and packaging plant to service Amgen’s rising demand in the United States, and it is projected to be operational by 2024. Amgen has been at the vanguard of biological medical innovation for more than 40 years, supporting patients with significant conditions in cancer, inflammation, cardiovascular disease, bone health, neurology, and nephrology.

Sandra Rodriguez-Toledo, vice president of Site Operations at the Amgen Biomanufacturing plant Ohio, will lead the new site, which is currently known as Amgen Ohio. “When fully operational, Amgen Ohio will be a cutting-edge production facility that will allow us to continue to provide new revolutionary medications to every patient, every time. We have recently begun hiring for technicians and engineers, as well as quality assurance, quality control, administrative, and management jobs, and will continue to do so in the future. I’m happy to be in the Columbus area, and I’m looking forward to welcoming new Amgen colleagues.”

Details on Amgen Ohio

Turner Construction is in charge of the project’s construction management, and CRB Group is in charge of the design. “We intend to invest $365 million in the construction of this location,” stated Sam Guhan, vice president of Engineering at Amgen. “Environmental sustainability will be a top emphasis, and we hope to design and build this factory to be LEED-certified. We will enhance energy efficiency and waste reduction, furthering Amgen’s goal of being carbon neutral over the next several years.”

“Amgen’s decision to build a cutting-edge facility where approximately 400 Ohioans will assemble and package medicines that will improve the lives of millions of people suffering from serious illnesses around the world is fantastic news for the state of Ohio. Amgen’s newest factory will be it is most efficient and sustainable ever, demonstrating the benefits of leveraging Ohio’s biotech skill and inventiveness “Ohio Governor Mike DeWine said.
