TLDRs:
- Cerebras shares fell 12% despite cloud revenue nearly quadrupling year over year.
- Investors focused on shrinking GAAP gross profit and rising infrastructure expenses.
- Management raised 2026 revenue and margin forecasts, signaling confidence in demand.
- Analysts remain broadly bullish, but execution risks continue to dominate sentiment.
Cerebras Systems (NASDAQ: CBRS) suffered a sharp selloff on Thursday after investors reacted negatively to the company’s second-quarter earnings report, sending the stock down about 12% in after-hours trading.
The decline came despite an extraordinary surge in cloud and services revenue, which jumped 281% year over year and became the company’s dominant source of revenue.
The market reaction highlighted a growing concern among investors: rapid artificial intelligence growth is not automatically translating into stronger profitability.
The earnings report showed that demand for Cerebras’ AI inference infrastructure remains robust, but the cost of scaling that business is increasing quickly. While management also raised its full-year revenue and margin outlook, Wall Street appeared more focused on deteriorating GAAP margins and the heavy investment required to expand data-center capacity.
Cloud Revenue Becomes Core Driver
Cerebras reported total GAAP revenue of $180.1 million for the quarter, representing a 74% increase from the same period last year. The standout figure was cloud and services revenue, which climbed to $126 million from $33 million a year earlier.
That shift dramatically changed the company’s revenue mix. Cloud and services accounted for roughly 70% of total revenue, compared with about 32% in the prior-year quarter. The transition suggests that Cerebras is increasingly evolving from a hardware-focused AI company into a provider of large-scale inference computing services.
However, hardware revenue moved in the opposite direction. Sales from that segment fell 23% year over year to $54.1 million, indicating that the company is relying more heavily on recurring cloud-related revenue streams to drive growth.
Profitability Concerns Take Center Stage
Despite the impressive top-line expansion, profitability weakened considerably. GAAP gross profit declined 20% to $25.6 million, while GAAP gross margin dropped to 14% from roughly 31% a year earlier. The deterioration in margin was the main factor behind the negative market reaction.
Cerebras also presented a core non-GAAP view of its business, showing revenue of $209.9 million and a gross margin of 41%. The difference between the GAAP and non-GAAP figures was driven by accounting adjustments related to customer warrants and pass-through sales.
Investors appeared unconvinced that the stronger adjusted metrics fully offset the pressure visible in the GAAP results.
Chief Financial Officer Bob Komin said that the company’s use of rented computing capacity reduced adjusted gross margin by about five percentage points. He added that increasing the share of owned infrastructure should help improve margins over time.
Upgraded 2026 Forecast
Even as the stock fell, management increased its 2026 outlook. Cerebras now expects core revenue of $880 million to $890 million, up from its previous forecast of $855 million to $865 million. The company also raised its projected core gross margin to a range of 41% to 43% and improved its operating margin outlook substantially.
The stronger guidance suggests that management sees continued momentum in AI inference demand and expects scale benefits to emerge as capacity utilization improves.
Chief Executive Officer Andrew Feldman said demand for fast inference remains extremely strong and that Cerebras is expanding aggressively to meet customer needs. The company currently has more than 600 megawatts of data-center capacity either operational or secured through contracts extending into 2027.
Balance Sheet Provides Support
One of the brighter aspects of the report was the company’s financial position. Cerebras ended the quarter with approximately $8.6 billion in cash, restricted cash, and short-term investments. Remaining performance obligations stood at $25.4 billion, providing visibility into future revenue.
Those figures suggest that the company has substantial resources to fund its rapid expansion, even if profitability remains under pressure in the near term.
Cerebras is positioning itself as a challenger to Nvidia in AI inference computing. Its wafer-scale architecture is designed to avoid some of the industry bottlenecks associated with high-bandwidth memory and advanced semiconductor packaging.
Wall Street Still Mostly Bullish
Although the earnings reaction was severe, analyst sentiment has not yet turned negative. Major firms including Citi, UBS, Needham, Morgan Stanley, and Wedbush had maintained buy ratings on the stock prior to the report, with price targets ranging from $273 to $340. Those targets may now be reassessed following the latest results.
The key debate is no longer whether demand exists for Cerebras’ technology. Instead, investors are questioning whether the company can build infrastructure fast enough, maintain high utilization, and eventually convert explosive cloud growth into sustainable GAAP profitability.
For now, the market has signaled that growth alone is not enough. Cerebras must demonstrate that its rapidly expanding AI cloud business can generate stronger margins and durable cash returns as it scales.
