These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Forward-looking statements in this Form 8-K include, but are not limited to, statements regarding anticipated growth in test volumes. These statements are based on management’s current expectations, forecasts and assumptions, and actual outcomes and results could differ materially from these statements due to a number of factors, some of which are beyond BillionToOne’s control. These and additional risks and uncertainties could affect BillionToOne’s financial and operating results and cause actual results to differ materially from those indicated by the forward-looking statements made in this Form 8-K. These risks and uncertainties include those discussed under the captions “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation” and elsewhere in BillionToOne’s most recently filed quarterly report on Form 10-Q, the annual report on Form 10-K and other filings BillionToOne makes with the Securities and Exchange Commission from time to time. The forward-looking statements in this Form 8-K are based on information available to BillionToOne as of the date hereof, and BillionToOne disclaims any obligation to update any forward-looking statements provided to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based, except as required by law. These forward-looking statements should not be relied upon as representing BillionToOne’s views as of any date subsequent to the date of this Form 8-K.\n\nSIGNATURES\n\nPursuant to the requirements of the Securities Exchange Act of 1934, as amended, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.\n\nBillionToOne, Inc.\n\nDate:\nJune 29, 2026\nBy:\n\n/s/ Ross Taylor\n\nName:\n\nRoss Taylor\n\nTitle:\n\nChief Financial Officer"}
