What Happened?

BillionToOne (BLLN) shares fell 15.6% on Feb. 23, pulling back sharply after a strong multi-month rally that followed the company’s IPO and early public market enthusiasm. The move pushed the stock near its 52-week low and marked one of its steepest single-day declines since listing.

The pullback came shortly after BillionToOne presented at the ViVE 2026 conference and ahead of its upcoming Q4 2025 earnings report scheduled for March 4. With limited trading history and a relatively small float, the stock has shown elevated volatility during periods of heavy volume.

Investors also appeared to lock in gains following a run-up that saw BLLN trade as high as $139 within the past year. The recent decline suggests sentiment shifted from growth optimism to near-term caution.

At the same time, broader pressure on high-multiple healthcare and diagnostics stocks added to selling activity. Stocks with premium valuations have been more sensitive to profit-taking in recent weeks.

Despite the sharp drop, analyst expectations remain elevated. The Street Target Price for BLLN stands at $135.29, compared with a Feb. 23 close of $72.

That implies nearly 88% upside based on consensus estimates, although coverage remains limited with seven total analyst estimates. The median price target is $145, while the high target reaches $160.

Street Targets data shows analysts have maintained bullish long-term views following the IPO. However, the gap between targets and the current price highlights increased uncertainty around execution and valuation.

What the Market Is Telling Us About BLLN Stock

The recent decline suggests investors are reassessing BillionToOne’s valuation after an aggressive post-IPO rally. At current levels, the stock trades at 9.6x NTM EV/revenue and over 100x NTM EV/EBITDA.

While revenue growth has been strong, profitability remains limited. On an LTM basis, BillionToOne posted an EBIT margin of -2.4% despite gross margins improving to 65.2%.

Financial results show meaningful operating leverage compared with prior years. Operating losses narrowed significantly in 2024 as revenue more than doubled year over year.

However, free cash flow remains negative, and the company continues to invest heavily in R&D and commercial expansion. That makes valuation especially sensitive to growth expectations.
