SHINE Medical Technologies is planning to expand its presence on Janesville’s south side.

The radioisotope company is working with a developer to build a combined 53,000 square-foot office headquarters and second isotope production facility just north of its existing property on Highway 51.

The Janesville City Council will vote Monday on a tax incremental financing agreement with the developer for the $10 million project, which would include just over $1 million in contributions from the city.

Economic Development Director Gale Price said the developer would own the property and SHINE would operate as a tenant. They hope to begin construction before the winter and finish by next fall.

SHINE is currently constructing its moly-99 production facility, which they hope can start producing commercially in 2022. The second facility would produce a different isotope, lutetium-177, used to fight cancer.
