BillionToOne experienced a sharp post-earnings sell-off despite maintaining full-year guidance and strong year-over-year revenue growth. Second quarter results showed slowing sequential growth, softer average selling prices, and significant margin compression versus Q1. The company trades at ~10x sales, a premium to May levels, with the growth story intact but near-term valuation less attractive.

Medical research stocks took a bath Thursday, helped by BillionToOne's second-quarter report, featuring a beat but no guidance raise.

While the top- and bottom-line numbers for BillionToOne (BLLN) give a sense of how the business performed in the quarter ended June 2026, it could be worth looking at how some of its key metrics compare to Wall Street estimates and year-ago values.
