Wolfspeed Stock: Is It a Speculative Buy After Recent Dip?

It’s a scene familiar to anyone who has covered Wall Street long enough: a stock, left for dead, finds a narrative. That narrative catches fire. The price soars on hope and momentum, detached from the bleak financials printed in its quarterly filings. Then, reality reports earnings. The air rushes out. The chart retraces, leaving burned speculators and a fundamental picture that remains, stubbornly, unchanged.

This is the story of Wolfspeed (NYSE: WOLF) in 2025. This spring, the semiconductor manufacturer became an unlikely meme for the AI trade. A bullish report from the Substack publication Citrini Research, which had earlier gained notoriety for its bearish call on SaaS stocks, ignited a speculative frenzy. Shares raced from the ashes of its 2024 bankruptcy to above $80. The thesis was seductive: Wolfspeed, as a leader in silicon carbide (SiC) chips, was poised to be the next great power play for artificial intelligence data centers.

But when the company reported its fiscal fourth-quarter results on August 19th, the narrative collided with the numbers. The stock cratered, giving back nearly all of its spring gains. The report was a stark reminder that corporate turnarounds are measured in years, not quarters, and are built on operating performance, not promotional pieces.

The core issue remains what it has been for years: negative gross margins. A company selling its products for less than the direct cost to make them is, in the most basic terms, destroying value with every sale. For Wolfspeed, this isn’t a temporary blip. It’s a structural problem born of a costly strategic bet. The company invested heavily to build a vertically integrated manufacturing empire for SiC wafers, betting that soaring demand from the electric vehicle (EV) sector would quickly fill its shiny new factories.

That bet has gone sideways. The technical challenge of moving to more efficient 200mm wafers proved immense. EV demand growth slowed. Then, in a body blow, Tesla—a bellwether for the industry—announced plans to drastically reduce its use of SiC in future models. The result, as seen in the Q4 report, is a 25% GAAP gross margin and negative 19.9% on an adjusted basis. Revenue fell 24% year-over-year to $149.6 million. The company is guiding, yet again, for more of the same: sales between $140-$160 million next quarter, with gross margins still underwater.

“The path to profitability for a capital-intensive manufacturer with negative gross margins is exceptionally narrow,” notes a recent analysis from semiconductor research firm Semiwise. “It requires either a dramatic, unforeseen surge in demand or a painful restructuring of that manufacturing footprint. Neither is a quick fix.”

The cash flow statement tells the story of this burden. Over the past nine months, Wolfspeed has burned through $180.3 million in operating cash and $253.7 million in free cash flow. It sits on $600 million in net debt. While exiting bankruptcy cleared some obligations, the high costs of maintaining and underutilizing its factories continue to bleed the company dry. This is precisely why the dominant model in chips is “fabless”—where companies like Nvidia and AMD design the chips but outsource the ruinously expensive manufacturing to foundries like Taiwan Semiconductor Manufacturing.

Yet, within the dismal report, there was a single, flickering data point of hope. Revenue from AI data centers more than doubled year-over-year. Management highlighted new design wins and pointed to the industry’s transition to more power-hungry 800-volt architectures as a permanent tailwind for SiC, which handles heat and power efficiency far better than traditional silicon. The opportunity is real. A report from the International Energy Agency last quarter highlighted that data center power demand is set to double by 2026, forcing a wholesale re-evaluation of power management—a core strength of SiC technology.

So, is the stock a buy on this drastic dip? The answer depends entirely on your tolerance for risk and your time horizon. This is not an investment in a stable business at a discount. It is a speculative wager on a binary outcome.

The bull case is that the AI data center opportunity accelerates faster than anyone expects, finally providing the volume needed to fill Wolfspeed’s factories and push adjusted gross margins past the breakeven point—which the company pegs at a daunting $800 million in quarterly revenue. If that happens, the leverage in the model could be powerful, and today’s price will look like a steal.

The bear case is simpler: the cash burn continues, the debt becomes burdensome, the promised demand fails to materialize at scale, and the company is forced into another financial reckoning. The history of capital-intensive manufacturers trying to outlast a demand drought is littered with casualties.

Having watched similar stories play out over decades—from solar to memory chips—I’ve learned that the market often underestimates how long a turnaround takes and overestimates how quickly a new market can save a struggling incumbent. The Citrini-fueled spike was a lesson in narrative over substance. The post-earnings plunge is a lesson in substance reasserting itself.

For the purely speculative portion of a portfolio, Wolfspeed represents a high-stakes call option on the SiC adoption curve in AI. The potential reward is significant. The risk of a total loss is equally present. For everyone else, particularly those who remember that profitability and positive cash flow are not optional features for a long-term investment, this remains a story to watch from the sidelines—a compelling, cautionary tale of hype, hope, and the hard math of a factory running half-empty.
