Wolfspeed Mohawk Valley Fab (MVF)

On the May 5, 2026 call, CFO Gregor van Issum stated that the transition to Mohawk Valley for full device production and the parallel realignment of go-to-market strategy across distinct verticals represent substantial operational and strategic milestones , while telling analysts that management expects continued underutilization costs until market demand aligns with expanded production capacity . Q3 FY26 non-GAAP gross margin was -20.6% with a ~$46M underutilization charge against ~$100M in Power Products revenue, ~90% of which came out of MVF. This is the single largest lever to fix — every additional wafer that yields cleanly through MVF compresses underutilization directly into margin.

Wolfspeed's October 29, 2025 release stated that GAAP and non-GAAP gross margin includes the impacts of underutilization costs related to the Mohawk Valley Fab and Siler City Fab. Underutilization was $47 million, compared to $26 million . CEO Robert Feurle framed the strategy as focusing on operational excellence by improving quality, cost, and speed across its facilities . MVF contributed $97M in Q1 FY26 revenue versus $49M a year prior — the fab is filling up, but underutilization charges roughly doubled YoY, which is the textbook profile of a ramp that needs faster yield learning per wafer.

Wolfspeed announced the appointment of Robert Feurle as Chief Executive Officer (CEO), effective May 1, 2025, following a comprehensive internal and external search by the Board of Directors. Feurle succeeds Thomas Werner, who is serving as interim Executive Chairman. Feurle is ex-ams-OSRAM (Opto Semis), Infineon (where he led IGBT and silicon-carbide product lines), and Micron. On the Q3 FY26 call he stated his three priorities as advancing technology leadership, demonstrating strict financial discipline, and driving operational excellence — quality, cost, speed. New CEOs at Y+12 months tend to back tools that visibly tighten the engineering feedback loop; this is the window.

Feurle on the Q3 FY26 call described that the transition to Mohawk Valley for full device production and the parallel realignment of go-to-market strategy across distinct verticals represent substantial operational and strategic milestones , and separately said the company has unified factory, supply chain, and enterprise data on a single Snowflake platform with AI-driven tools for real-time insights. Translation for an AI-vision vendor: the data plumbing is being built right now, the engineering culture is being told to use AI tools, and the defect-classification layer is the obvious next gap — Snowflake gives them the warehouse, not the SEM/optical inspection classifier.

LinkedIn shows active Marcy, NY listings for Yield Engineer, Defect Yield Engineer, and Defect/Yield Engineering Intern under Wolfspeed. A ZipRecruiter snapshot of the Marcy Yield Engineer req lists requirements including strong semiconductor process knowledge an yield improvement · Background in device physics and experience analyzing PCM and probe data · Proficient in statistical data analysis using JMP and able to write scripts to pull relevant data (in-fab monitors, defect, PCM, probe, etc..) . Wolfspeed is trying to solve this in-house today; an external defect-classifier platform competes with hiring more PCM/JMP-scripting engineers and waiting for them to ramp.

Per the Schumer announcement, the proposed CHIPS funding will support the Mohawk Valley fab to increase its production capacity by approximately 30% , with the disbursement of funds will be conditioned upon the achievement of certain operational and construction milestones and other requirements . Capacity adds without yield throughput just expands the underutilization line — every milestone Wolfspeed signs up for converts directly into pressure on the MVF yield/defect-engineering bench.
