Quantum-Si — Third Quarter 2026 Earnings Summary

Q3 2026 revenue declined to $212,000 from $552,000 in the prior-year period, while the company reduced total operating expenses to $23.9 million from $40.0 million, resulting in a net loss of $22.3 million compared to $35.7 million previously.
Full-year 2026 revenue guidance remains at approximately $1.0 million, though adjusted total operating expenses and total cash usage guidance were lowered to $87.0 million or less from previous estimates of $98.0 million and $93.0 million, respectively.
The company expects 2026 and the first half of 2027 to be a transition period from Platinum to Proteus, with a commercial launch targeted for Q2 2027 and a projected cash runway extending into Q4 2028.
A reduction in force affecting approximately 20% of headcount was completed in Q3 2026, generating $2.9 million in restructuring costs and expected to yield $12 million in annual operating expense savings.
Interim data indicates Proteus delivers approximately 30 times more sequencing output per chamber than Platinum Pro, with the company confident in addressing prior instrument variability issues and maintaining supply chain readiness for the launch.
