Cerebras Systems delivered $510 million in revenue for the fiscal year ended December 2025, a 75.7 percent increase from the prior year, and converted that top line into $237.8 million of net income. QuantumScape, by contrast, recorded zero revenue and a $435.1 million net loss over the same period as it continues pre-commercial testing of its solid-state battery. The divergence frames a stark choice for hardware investors: a profitable AI infrastructure play scaling into global demand, or a pre-revenue battery developer betting on automotive partnerships that have yet to produce a commercial order.
The AI chip maker is already profitable
Cerebras builds wafer-scale processors for AI training and inference, selling the CS-3 platform through cloud and on-premises deployments across North America, Asia, Europe and the Middle East. The 46.6 percent net margin reported for fiscal 2025 marks a transition from cash-intensive hardware startup to profitable operator, though free cash flow remained negative at -$392.8 million as capital expenditures outpaced operating cash generation. A current ratio of 2.1 times suggests adequate short-term liquidity, while the negative debt-to-equity ratio of -0.5 times reflects liabilities exceeding shareholder equity on the December 2025 balance sheet. Investors can now apply a forward price-to-earnings multiple, a luxury unavailable for most hardware peers at this stage.
The battery developer still has no product revenue
QuantumScape's FY2025 results show a company entirely in the laboratory phase. The QSE-5 cell is being developed under a long-standing partnership with Volkswagen and a newer multi-year agreement with Honda, concentrating commercial risk in two automakers. The $278.8 million free cash flow burn is lower than Cerebras in absolute terms, but it funds research rather than production ramp. A 15.9 times current ratio signals a large cash cushion relative to near-term obligations, and a 0.1 times debt-to-equity ratio indicates minimal leverage. Neither metric generates returns until a battery ships in volume.
Valuation models diverge on timeline
Cerebras offers a forward earnings multiple grounded in realized revenue growth; QuantumScape trades on option value tied to milestones that have repeatedly slipped across the industry. The hardware maker's 75.7 percent year-over-year revenue increase provides a measurable trajectory. The battery developer's zero-revenue baseline provides none. Both companies burn cash to expand capacity, but only one has demonstrated that customers will pay for the output.
