04-03-2026

MENLO PARK, Calif., March 04, 2026 (GLOBE NEWSWIRE) -- BillionToOne, Inc. (NASDAQ: BLLN), a next-generation molecular diagnostics company with a mission to create powerful and accurate tests that are accessible to all, today reported its financial results for the fourth quarter and full year ended December 31, 2025 and raised guidance for full year 2026.

Financial Highlights:

  • Total revenue of $96.1 million in the fourth quarter of 2025, compared to $45.1 million in the fourth quarter of 2024, an increase of 113%.
  • Prenatal clinical testing revenue was $86.1 million in the fourth quarter of 2025, an increase of 99% from the fourth quarter 2024.
  • Oncology clinical testing revenue was $9.1 million in the fourth quarter of 2025, more than 8x higher than the $1.1 million reported in the fourth quarter of 2024.
  • Gross profit margin was 71% in the fourth quarter of 2025, compared to 57% in the fourth quarter of 2024, a 14 percentage-point increase year-over-year.
  • 170,000 tests delivered in the fourth quarter of 2025, compared to 116,000 tests delivered in the fourth quarter of 2024, an increase of 47%.
  • Operating income of $10.3 million in the fourth quarter of 2025, compared to a $11.7 million operating loss in the fourth quarter of 2024.
  • Net cash flow, excluding the net proceeds received from the issuance of common stock in connection with the IPO, was $8.8 million in the fourth quarter of 2025 and $12.5 million in the full year 2025.
  • Raised 2026 full year revenue guidance to be in a range of $430 million to $445 million, which represents 41% to 46% growth over 2025.
  • Expects positive operating income for the full year 2026.

Recent Operating Highlights:

  • In February, we launched our expanded Red Blood Cell Fetal Antigen NIPT offering and our Platelet Fetal Antigen NIPT offering in prenatal product lines. These two products represent the first, and only, non-invasive prenatal tests in the U.S. designed to determine fetal antigen status across both red blood cell and platelet antigens in pregnancies affected by or at risk for Hemolytic Disease of the Fetus and Newborn (HDFN) and Fetal and Neonatal Alloimmune Thrombocytopenia (FNAIT).
  • Also in Q1 of 2026, we launched Northstar PGx and Northstar Select CH in oncology products. Northstar PGx and Northstar CH are add-on applications for our Northstar Select test, and expand the Northstar platform beyond genomic profiling to address chemotherapy safety (PGx) and clonal hematopoiesis (CH)—two critical decision points in selecting the right therapy for patients.

"2025 demonstrated how the compounding power of a differentiated technology platform, category-defining products, and disciplined execution can produce an extraordinary outcome,” said Dr. Oguzhan Atay, Co-Founder and CEO of BillionToOne. "With new prenatal and oncology products already launched, expanding payer coverage, and a growing base of providers choosing our tests, we are executing to solve the hardest problems in healthcare and give patients the answers they need. Entering 2026, we believe we are still in the earliest chapters of what is possible, and remain confident that our smNGS platform will continue to unlock diagnostic capabilities that transform patient lives one molecule at a time.”
