Wolfspeed: The SiC Bet Wall Street Is Still Debating

From a 52-week low of $1.16 to a peak of $80.82 — that is the kind of move that forces you to stop and ask what actually changed. The stock has since pulled back sharply and was trading around $29 to $34 as of mid-July 2026, but the rally from the bottom is still one of the more striking stories in the semiconductor space this year.

Wolfspeed (NYSE: WOLF) emerged from Chapter 11 on September 29, 2025, raised approximately $475.9 million in gross proceeds through a refinancing in March 2026, and then did something unexpected: it started telling an AI infrastructure story. A serious one. The company reported sequential quarterly growth in AI data center applications of approximately 30% and launched what it described as the first commercially available 10 kV silicon carbide power MOSFET for grid modernization and AI data center infrastructure.

It also introduced a next-generation TOLT portfolio aimed directly at AI data center demand, and signed a memorandum of understanding with GE Aerospace on June 8, 2026 to accelerate adoption of high-voltage silicon carbide technology. That is not a small name to be working with.

Here is the part that gets interesting. Research notes framing Wolfspeed’s fabs as scarce, hard-to-replace AI infrastructure assets — despite deep current losses and the recent Chapter 11 exit — helped push the stock up sharply in the spring. The market was pricing in a story that the income statement has not yet confirmed.

The Numbers

Q3 fiscal 2026 results, reported May 5, 2026:

• Revenue: $150.2 million, aligned with the midpoint of company guidance but approximately 28% below street consensus of around $209 million
• GAAP net loss: $120 million
• Non-GAAP gross margin: negative 20.6% (an improvement from Q2, but still deeply negative)
• Adjusted EBITDA: negative $62 million
• Operating cash flow: negative $84 million
• Non-GAAP diluted EPS: negative $3.26, versus the consensus estimate of negative $3.78 — a beat on that metric
• Q4 FY2026 guidance: revenue of $140 million to $160 million, with non-GAAP gross margins expected to remain negative

The EPS beat was real. The revenue miss versus street expectations was also real. The market’s reaction — a roughly 7% aftermarket jump — said more about positioning and momentum than it did about the underlying results.

Why the Stock Kept Moving

What’s interesting is that the fundamentals alone don’t fully explain the move from the 52-week low.

The gap between the asset story and the income statement is exactly where the volatility lives. Wolfspeed is a bet on silicon carbide becoming essential infrastructure for AI data centers — the same way copper wiring became essential for every building. The company now sits at the crossroads of AI data centers, energy transition, and geopolitical chip spending. That is a powerful combination of themes, even when the numbers are still deeply in the red.

Slight tangent, but it matters: Wolfspeed also created a dedicated data center solutions team in the San Francisco Bay Area in May 2026. That is a structural move, not a press release. It signals the company is treating AI data centers as a distinct commercial priority, not an afterthought.

What the Bear Case Looks Like

The honest version of the bear case: Wolfspeed is still generating negative EBITDA. Revenue is declining year-over-year. Gross margins remain negative. The stock rallied as if the AI data center opportunity is already secured, but the company hasn’t shown it can convert that opportunity into earnings — or even into flat gross margins — yet.

Underutilization at the Mohawk Valley fab is weighing on margins by roughly $46 million per quarter, per management’s own figures. That does not go away until revenue ramps meaningfully. And the automotive market — historically a key revenue driver — is soft, with qualification cycle delays pushing out revenue recognition.

There is also an active patent infringement lawsuit Wolfspeed filed against Navitas Semiconductor, adding legal risk and cost to an already stretched balance sheet.

Bull / Base / Bear

• Bull: Silicon carbide power modules become mandatory for next-generation AI data centers. Wolfspeed’s 200mm Mohawk Valley fab commands pricing power no competitor can match for years. AI data center revenue accelerates sharply in fiscal 2027, pulling gross margins toward breakeven ahead of schedule.
• Base: AI data center demand is real but slower to ramp than the stock has implied. Wolfspeed grows revenue gradually, continues cutting losses, and trades in a wide range around current levels as the market waits for proof of margin improvement.
• Bear: Hyperscalers source silicon carbide power solutions from multiple suppliers before Wolfspeed achieves profitability. Ongoing losses, negative cash flow, and potential dilution pressure the stock back toward the lower end of its recent trading range.

The Date to Watch

Wolfspeed is confirmed to report its next earnings on August 19, 2026, after market close — that is the Q4 fiscal 2026 report. Some sources indicate a possible date of August 24; verify closer to the date. Either way, the market will want to see whether AI data center revenue continued its roughly 30% sequential growth, whether gross margins showed further improvement toward breakeven, and whether management upgraded its forward outlook on SiC power demand.

The stock has already moved a long way from its lows. The next earnings report either justifies the current price or forces a significant reset. That is the only question worth tracking right now.
