In January 2026, PacBio announced preliminary unaudited revenue for Q4 2025 and full-year 2025, reporting a 14% year-over-year revenue growth for Q4 2025. Despite a significant publication from Radboud University Medical Center highlighting the impact of PacBio's HiFi long-read sequencing technology in identifying genetic causes of rare diseases, the company's shares declined by 7.9% on January 15, 2025. In August 2025, PacBio reported Q2 CY2025 results, surpassing market revenue expectations with a 10.4% year-on-year sales increase. In May 2025, the company's Q1 earnings revealed red flags such as a 4.3% fall in revenue, lowered guidance, a significant GAAP net loss, rising debt-to-equity levels, excessive share-based compensation, and insider selling.
