The proposed Lonza Clermont County facility in Williamsburg Township is shaping up as one of the largest pharmaceutical manufacturing bets in Ohio’s recent history, with the Swiss contract development and manufacturing giant weighing an investment of roughly $1 billion. Lonza USA Inc. is considering the project on two parcels totaling 161 acres in the northwest corner of Half Acre Road and State Route 32, the James A. Rhodes Appalachian Highway, on land currently owned by Clermont County and sitting at a highway interchange. The 120-year-old company is the world’s largest contract development and manufacturing operation serving the pharma and biotech industry, and the new biotech manufacturing plant would create 650 full-time-equivalent positions while generating around $50 million in new annual payroll. The decision moved a step closer on Monday, June 29, 2026, when the Ohio Tax Credit Authority approved a 1.860 percent, 20-year Job Creation Tax Credit for the project, part of a broader package of seven economic development projects announced by Governor Mike DeWine that together represent more than $1.1 billion in investment. The plant remains a potential future commitment rather than a confirmed build, since it is still subject to Lonza’s internal due diligence and final approval by the company’s Board of Directors. Should it proceed, the facility would anchor a growing cluster of life sciences and advanced manufacturing investment in southwest Ohio and deepen the region’s role in the national biologics supply chain.

Why Williamsburg Township and Clermont County Are Drawing Pharma Investment

Ohio did not win this opportunity by default. According to reporting tied to the Cincinnati Business Courier, the state competed against Texas, North Carolina and Virginia for the Lonza project, all of which carry established biomanufacturing corridors and aggressive incentive programs. Williamsburg Township already has a track record of landing large industrial commitments, most notably the $550 million Nestlé Purina PetCare factory announced in Clermont County in 2020, which demonstrated that the area can support major facilities with the road access, utilities and acreage that capital-intensive plants demand. The Lonza site’s position at an SR 32 interchange gives it the logistics profile such projects require. The broader signal is Ohio’s hardening reputation as a pharmaceutical manufacturing destination. Just up the road in central Ohio, Amgen broke ground on a biomanufacturing plant in New Albany backed by a $365 million investment, a project that helped seed roughly 400 jobs and showed global drugmakers that the state could deliver skilled biotech labor and regulatory-grade construction. Lonza itself has been expanding aggressively across the United States, including its $1.2 billion acquisition of a large-scale mammalian manufacturing site in Vacaville, California, underscoring how the contract manufacturing sector is racing to add domestic capacity as drugmakers reshore production. A Clermont County plant would slot neatly into that strategy and reinforce a Cincinnati-to-Columbus life sciences belt that is increasingly visible to site selectors nationwide.

Lonza Clermont County Facility Timeline and What Comes Next

The most important caveat is that the project is not yet a done deal. The Ohio Department of Development has been explicit that the investment hinges on successful due diligence and approval by Lonza’s Board of Directors, so the immediate milestone is the company’s internal go or no-go decision rather than a construction start. If Lonza commits, the next steps would involve finalizing the land transfer from Clermont County, completing site engineering and securing the permits a biologics-grade facility requires. The 20-year span of the approved Job Creation Tax Credit signals that both the company and the state are framing this as a long-horizon commitment, with the payroll and employment benefits accruing over decades rather than a single construction cycle. The payoff on completion would be substantial for the local economy, with 650 direct jobs and $50 million in annual payroll feeding into Clermont County’s tax base and supporting indirect employment across construction, suppliers and services. Open questions remain around the precise construction timeline, the main contractor and the facility’s final scope, none of which have been publicly disclosed while the project sits in its due diligence phase.
