Pacific Biosciences of California, Inc. reported Q1 2026 revenue of $37.2 million, essentially flat year over year, with higher consumable sales offsetting softer instrument and service revenue. Revio system placements rose while Vega unit volumes and pricing were pressured by promotions and funding constraints.
Gross profit improved to $12.8 million from a gross loss of $1.4 million a year earlier as cost of revenue declined sharply. The company posted a much smaller net loss of $8.3 million versus $426.1 million in Q1 2025, largely because the prior period included large one-time amortization and impairment charges and the current quarter benefited from a $45.8 million gain on an asset sale to Illumina.
Cash, cash equivalents and investments totaled $276.0 million as of March 31, 2026, only slightly below year-end. PacBio highlights continued restructuring-driven operating expense reductions, a new license and settlement agreement with PGI that creates fixed payments through 2029, and an ongoing focus on driving HiFi sequencing adoption via the Revio and Vega platforms and upcoming SPRQ-Nx consumables.
