CBRS stock surged 18% in extended trading Thursday after Cerebras Systems reported better-than-expected third-quarter revenue and revealed a new deal with Microsoft. The sharp move offered investors a fresh reason to reconsider the AI chipmaker, whose shares have fallen about 47% since its Nasdaq debut in May.
CBRS Stock Jumps After Powerful Earnings Report
Cerebras reported core revenue of $230.9 million for the third quarter, beating the $214.7 million expected by analysts surveyed by LSEG. Revenue increased 70% from $135.7 million a year earlier, although that growth rate was slower than the 103% expansion reported in the second quarter.
The company reported a loss of 67 cents per share. CNBC noted that the comparison with the 14-cent loss expected by analysts was not immediately clear, making revenue and forward guidance the main focus for investors.
Despite the reported loss, the market reacted positively to the company’s stronger sales performance and bullish outlook. Cerebras CEO Andrew Feldman said the business is benefiting from demand for alternatives to traditional graphics processing units, or GPUs.
“I think there is opportunity created by, particularly on the hardware side, the sale of hardware, where long lead times in GPUs and more expense creates opportunity for us,” Feldman told CNBC.
Microsoft Partnership Creates Major Growth Catalyst
The biggest surprise in the report was Cerebras’ newly announced relationship with Microsoft, one of the world’s largest cloud providers. Feldman said Microsoft signed the agreement in October and that revenue from the partnership is expected to begin appearing in the first quarter of 2027.
“We believe revenue begins to show up in Q1 ’27,” Feldman said.
The agreement strengthens Cerebras’ position in the competitive AI infrastructure market. The company has also secured relationships with Amazon and Oracle, giving it connections with three major cloud providers. Those partnerships could help Cerebras expand its customer base beyond individual technology companies and into large-scale cloud computing platforms.
Executives were scheduled to discuss the Microsoft agreement during a conference call with analysts. The company is also evaluating financing options as it prepares to meet rising demand for its AI computing systems.
Why the Microsoft Deal Matters
- Microsoft could provide Cerebras with a significant enterprise customer.
- Cloud partnerships may accelerate adoption of Cerebras’ AI systems.
- Revenue from the agreement is expected to begin in early 2027.
- The deal may help diversify the market beyond Nvidia-based infrastructure.
Explosive Fourth-Quarter Guidance Beats Wall Street
Cerebras delivered an especially optimistic forecast for the fourth quarter. The company expects revenue between $310 million and $330 million, compared with the $271 million analysts had anticipated.
Management also projected a core gross margin of 47% to 49%. That outlook was well above the 42.1% margin expected by analysts, suggesting that Cerebras believes it can improve profitability while scaling production and meeting demand.
The company said it expects revenue to triple in 2027, implying approximately $2.85 billion in sales. Analysts surveyed by LSEG were expecting slightly higher revenue of $2.92 billion, meaning the long-term forecast was strong but not as aggressive as Wall Street’s estimate.
Cerebras Challenges Nvidia in the AI Chip Market
Cerebras is attempting to challenge Nvidia in the fast-growing AI chip industry. Nvidia remains the dominant supplier of specialized processors used to train and operate artificial intelligence systems, but high prices and long delivery times are creating opportunities for competitors.
Feldman’s comments suggest that Cerebras is positioning its hardware as a faster or more cost-effective option for customers that cannot easily secure Nvidia GPUs. However, the company still faces significant challenges, including competition from established chipmakers, the need for additional financing and the difficulty of converting cloud relationships into sustained revenue.
For investors watching CBRS stock, the Microsoft agreement could become a critical test. The stock’s 18% after-hours gain shows that traders welcomed the earnings beat, but the shares remain well below their initial public offering level. Sustained customer growth and successful execution will likely determine whether the latest rally develops into a lasting recovery.
What Investors Should Watch Next
The next several quarters will be important for Cerebras. Investors will be looking for evidence that Microsoft-related revenue begins on schedule, that Amazon and Oracle relationships expand, and that the company can maintain strong margins while increasing production.
The broader AI chip market also remains highly competitive. Cerebras’ growth forecast is impressive, but the company must continue proving that it can scale beyond early partnerships. As per CNBC’s reporting, the company’s management believes demand is ramping quickly, but financing and execution remain important risks.
Is CBRS stock a buy after the surge?
The sharp rally reflects improved sentiment after Cerebras exceeded revenue expectations and announced the Microsoft deal. However, investors should weigh the company’s losses, financing needs and nearly 47% decline since its IPO before making any investment decision.
What was Cerebras’ third-quarter revenue?
Cerebras reported core third-quarter revenue of $230.9 million, above the $214.7 million expected by LSEG-surveyed analysts.
When will the Microsoft deal contribute revenue?
CEO Andrew Feldman said revenue from Microsoft is expected to begin appearing in the first quarter of 2027.
How much revenue does Cerebras expect in the fourth quarter?
Cerebras forecast fourth-quarter revenue of $310 million to $330 million, exceeding the $271 million analyst consensus.
Why is Cerebras competing with Nvidia?
Cerebras is targeting demand for AI computing hardware as customers face high costs and long lead times for Nvidia GPUs. The company hopes its systems can provide an alternative for cloud and enterprise customers.
