Cerebras Systems (NASDAQ: CBRS) Reports Q2 2026: Cloud Revenue Up 281%, But IPO-Related Costs Deepen Losses

Q2 2026 Results

Cerebras Systems (NASDAQ: CBRS) reported Q2 2026 GAAP revenue of $180.1 million, up 74.3% year-over-year, while GAAP EPS came in at -$2.98, missing the -$1.41 analyst consensus by 111.4%. The headline growth figures masked a significant divergence: total GAAP operating expenses surged 463.2% year-over-year to $502.8 million, driving the GAAP operating loss from -$57.2 million in Q2 2025 to -$477.2 million in Q2 2026.

Key Metrics

• Cloud revenue: GAAP cloud and other services revenue reached $126.0 million, up 281% year-over-year; core cloud revenue reached $127.7 million, up 287% year-over-year.
• Core (non-GAAP) total revenue: $209.9 million, up 103.2% year-over-year, reflecting the exclusion of pass-through revenues and addition of amortized customer warrant assets.
• GAAP gross margin: 14% for Q2 2026; core gross margin of 41%, an improvement of approximately 940 basis points from Q2 2025.
• Operating expenses: R&D rose 426.8% YoY to $320.2 million; G&A rose 829.9% YoY to $95.7 million; Sales and Marketing rose 377.0% YoY to $87.0 million.
• Liquidity: Cash, cash equivalents, restricted cash, and short-term investments totaled $8.6 billion as of June 30, 2026, reflecting $6.4 billion in gross IPO proceeds raised during the period.

What Drove the Results

The adjusted EPS of -$0.04 beat the -$0.17 consensus by 77.1%, while GAAP EPS of -$2.98 missed the -$1.41 consensus by 111.4%. The gap between GAAP and adjusted results is driven primarily by $386.6 million in stock-based compensation recognized in the first half of 2026, compared to $22.4 million in the first half of 2025, a direct consequence of the company's IPO. This non-cash expense is concentrated in the R&D, G&A, and Sales and Marketing line items, inflating each significantly relative to the prior year.

Core gross margin of 41% improved approximately 940 basis points versus Q2 2025, and core operating margin of -16% improved approximately 2,600 basis points year-over-year, indicating the underlying unit economics of the cloud business are strengthening. Capital expenditure for the first half of 2026 reached $548.9 million, up 196.5% from $185.1 million in the same period of 2025, as the company accelerated data center acquisitions. Free cash flow for the first six months of 2026 was -$596.4 million.

Remaining performance obligations stood at $25.4 billion as of June 30, 2026, a structural demand signal that reflects contracted future revenue well beyond current quarterly results.

Guidance and Business Developments

Cerebras raised its full-year 2026 core revenue guidance from a range of $855 million to $865 million to a new range of $880 million to $890 million, versus the prior analyst consensus of $867.7 million. For Q3 2026, the company guided core revenue of $214 million to $216 million, compared to the $212.3 million analyst estimate. Full-year 2026 core operating margin is now expected in the range of -19% to -17%, and core gross margin in the range of 41% to 43%.

On the operational side, Cerebras reported 600 megawatts of data center capacity now under contract, manufacturing capacity set to increase more than 10 times during 2026 through expanded lines at Flex, Sanmina, and Rocket EMS, and secured TSMC wafer supply for continued growth. The company also announced it served as an OpenAI launch partner for the GPT-5.6 Sol model at 750 tokens per second, and deepened partnerships with AMD and AWS toward disaggregated inference solutions expected to enter production in Q4 2026 and Q1 2027, respectively. New cloud capacity agreements were signed with Cognition and Lovable, and the company cited CrowdStrike, Block, Figma, AlphaSense, and GSK as active customers.

Wall Street View

Analyst consensus heading into the print was broadly constructive, with the majority of covering firms at Buy or equivalent. No specific rating changes or new price targets were available in the source data following the release.

Investor Takeaway

The central question for CBRS investors is whether the $25.4 billion remaining performance obligations backlog and the improving core operating margins can absorb the scale of infrastructure investment underway, with first-half capital expenditure already nearly tripling year-over-year to $548.9 million. The company's 2027 plan to more than triple revenue from the raised 2026 guidance midpoint implies a step-change in execution that will require the data center, manufacturing, and supply chain capacity expansions currently in progress to deliver on schedule.
