Jubilant HollisterStier LLC is on track to complete its fourth sterile fill-finish line by mid 2026, bringing the company’s multiyear $285 million expansion of its contract manufacturing injectable product lines to completion, says content marketing specialist Sabrina Zirkle.

Located at 3525 N. Regal, Jubilant HollisterStier broke ground on its expansion project in November 2021. The first phase, a 50,000-square-foot third line expansion, was completed in 2024 and began commercial production in October. The second and final phase is underway and will expand the facility by 160,000 square feet. Once completed, the third and fourth lines are expected to increase the company’s production capacity to over 60 million vials, serving over 300 million patients around the world, the Journal previously reported.

Additionally, the two new lines are expected to create over 400 new jobs, bringing the company’s total workforce to over 1,000. The company has already started hiring new team members for the expanded lines, Zirkle says.

According to the Journal of Business’s Largest Employer’s List, as of Dec. 12, Jubilant HollisterStier employed just over 1,100 full-time workers at its Spokane facility, up from 731 when it first broke ground in the fall of 2021.

Spokane Valley-based Lydig Construction Inc. is the contractor, and the California office of IPS-Integrated Project Services LLC is providing design and engineering services.

As the company completes the expansion of the contract manufacturing side of its business, it has begun laying out plans to expand its campus with the addition of a new $18.5 million building to relocate the company’s allergens processing business unit.

As previously reported by the Journal, the proposed two-story structure is planned on two parcels of land totaling nearly an acre in size, at 2813 and 2835 E. Gordon, just north of the Jubilant HollisterStier campus.

The two parcels of land for the project were purchased in October for $650,000 by Jubilant HollisterStier, Spokane County tax records show.

The proposed new structure will house HollisterStier Allergy’s raw materials, compounding functions, biological source materials storage, and research and laboratory space, according to a predevelopment application for the project, the Journal reported in January.

Lydig Construction is the contractor for the allergens project; an architect has not yet been selected.
