Wolfspeed (WOLF) is drawing intensified short interest from institutional players concerned the company cannot sustain its Silicon Carbide (SiC) fab buildout through its current cash burn trajectory. FY2025 data from SEC EDGAR shows revenue of $757.6M, down 6.1% year-over-year, with a gross margin of -16.1% and a net margin of -212.4%, implying losses far outpacing the top line. Diluted EPS came in at -$11.39, a figure that underscores how capital-intensive the Mohawk Valley and John Palmour Manufacturing Center ramp has become.
The short thesis is straightforward: WOLF is burning cash at a rate that makes near-term solvency a live question. With revenue shrinking and gross margins still deeply negative, the company needs either a dramatic yield improvement at its new fabs, a large capital injection, or a significant customer pull-forward to avoid a distressed financing event. The EV and industrial SiC market slowdown has made demand visibility murkier, removing one of the key bull pillars.
The bull case rests on the strategic value of WOLF's SiC technology position — it remains one of the few vertically integrated SiC suppliers at scale, and any recovery in EV adoption or a U.S. government-backed financing deal (the company has pursued CHIPS Act funding) could dramatically change the calculus. A fab ramp that hits cost targets would flip gross margins positive and compress losses rapidly.
The bear case is that negative gross margins mean the company loses money on every wafer shipped today, and the timeline to margin inflection keeps slipping. With short positions growing and the balance sheet under pressure, dilutive equity raises or debt restructuring remain high-probability outcomes that cap upside for equity holders even in a recovery scenario.
Key catalysts to watch: any CHIPS Act loan finalization, quarterly gross margin trajectory at Mohawk Valley, and whether WOLF can maintain or grow its design-win pipeline with Tier 1 auto customers. A miss on any of these could accelerate the short thesis materially.
