Wall Street Doubles Down on Wolfspeed Short Positions Over Cash Burn Fears
Wall Street is piling into short positions on Wolfspeed amid escalating cash burn fears, with the SiC chipmaker posting a -212.4% net margin and -$11.39 diluted EPS on $757.6M in declining revenue. The short thesis centers on whether WOLF can fund its fab ramp before capital runs out, creating a binary setup between restructuring survival and distressed dilution or default.

The read · Jul 8
WOLF sits at the intersection of a compelling long-term SiC technology position and a near-term cash burn crisis — the question is whether equity holders survive the ramp or get wiped out by dilution first.
Wrong if
A CHIPS Act direct loan announcement, a large strategic equity investment (e.g., from an auto OEM), or a surprise gross margin beat driven by fab yield improvement could trigger a violent short squeeze given already elevated short interest.

The story1 min read
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.
The read, in fullWhy it matters
With -16.1% gross margins on $757.6M in shrinking revenue and -$11.39 diluted EPS, WOLF is losing money at the unit economics level before SG&A or capex — the fab ramp has not yet inflected, and growing Wall Street short interest signals institutional consensus that a dilutive financing event is likely before margins turn. Revenue declining 6.1% YoY removes the 'growth justifies burn' argument and tightens the window for a self-funded recovery.

▲ The case it holds
WOLF is one of the only vertically integrated SiC suppliers at scale globally, and a successful Mohawk Valley ramp hitting positive gross margins — combined with a potential CHIPS Act loan — could rapidly compress losses and render the current short thesis obsolete.
▼ The case it breaks
With gross margins still deeply negative (-16.1%) and revenue falling, WOLF must access external capital to fund operations, making dilutive equity issuance or debt restructuring a high-probability near-term event that structurally caps equity upside even in a bull scenario.
