Coherent has put another renovation of its Sherman semiconductor plant on file with the state, the 11th project the company has registered at the South U.S. 75 site since February.
The latest filing, registered Sept. 18 by the Texas Department of Licensing and Regulation, is titled "Zone 2 WAT/ORT Cleanroom." It describes an $8 million renovation of an existing fabrication lab covering 6,030 square feet at 6800 S. U.S. 75.
Work is scheduled to start Feb. 15, 2027, and wrap up Aug. 15, 2027, according to the filing, and the state's review of the project is marked complete.
The property owner on the filing is Finisar Sherman RE Holdco LLC, and the design firm is MJMc Architects of Farmers Branch.

The bigger plan
At the city's Mayor's Roundtable on Oct. 2, Coherent executive vice president Beck Mason said the company would invest more than $1.2 billion in new fab infrastructure in Sherman, KTEN reported. The state filings do not say whether the renovations are part of that investment, and Coherent's announcement did not include a timeline in the remarks the station reported.
