Recent Operating Highlights:
Today, we announced the upcoming expansion of our Unity Fetal Risk Screen with the addition of a 130-gene panel, which is the largest single-gene NIPT panel available. Our expanded panel significantly broadens the addressable market for Unity and reinforces BillionToOne's position as the leader in cfDNA testing for recessive conditions. This expanded panel will be available commercially on August 17, 2026.
Today, we announced the planned launch of Northstar Origin, an add-on tissue-of-origin feature for our Northstar Select test that can benefit patients with unknown or uncertain diagnoses. This feature will be available commercially on September 1, 2026.
In June 2026, we announced the peer-reviewed data published in The Journal of Liquid Biopsy, in collaboration with Allegheny Health Network, demonstrating that Northstar Response was a stronger predictor of survival than standard-of-care imaging in patients with advanced solid tumors receiving immunotherapy or immunotherapy combination therapy.
"Our second quarter demonstrated the durability of our model, with our differentiated technology platform, category-defining products, and disciplined execution driving continued growth and profitability," said Dr. Oguzhan Atay, Co-Founder and CEO of BillionToOne. "We grew revenue 64% year-over-year to a $438

million annualized run-rate while advancing our product roadmap with the launch of Unity Confirm and the upcoming launches of our expanded Fetal Risk Screen and Northstar Origin. We believe we are still in the earliest chapters of what our smNGS platform can achieve, and we remain relentlessly focused on transforming molecular diagnostics and healthcare.”

Second Quarter 2026 Financial Results
Total revenue was $109.4 million in the second quarter of 2026 compared to $66.6 million in the second quarter of 2025, an increase of 64%. The increase in total revenue was driven by a 35% increase in the number of total tests delivered and a 21% increase in Overall ASP. Both prenatal and oncology delivered strong test volume growth year-over-year.
Gross profit was $77.1 million in the second quarter of 2026, compared to $43.5 million in the second quarter of 2025, representing a gross margin of 70% in the second quarter of 2026 and 65% in the second quarter of 2025. An increase in Overall ASP drove the improvement in gross profit margin compared to the second quarter of 2025. Overall cost-per-test increased slightly in the second quarter of 2026 compared to last year, as improvements in cost-per-test for both of our oncology products and for our prenatal products were offset by the faster growth of our oncology products, which have higher costs-per-test.
Total operating expenses were $71.6 million in the second quarter of 2026, compared to $45.1 million in the second quarter of 2025 an increase of 59%.
Income from operations was $5.5 million in the second quarter of 2026, compared to a loss from operations of $1.6 million in the second quarter of 2025. Operating margin was 5% in the second quarter of 2026.
Net income in the second quarter of 2026 was $8.1 million, or $0.15 per diluted share, compared to a net loss of $0.2 million, or $(0.02) per diluted share, in the second quarter of 2025.

Forward-Looking Statements
This press release contains certain forward-looking statements within the meaning of federal securities laws. 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 press release include, but are not limited to, statements regarding revenue, income and other financial information for the full year of 2026. 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 that 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 press release. 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 press release 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.

Non-GAAP financial measures
We use certain non-GAAP financial measures to supplement our unaudited financial results, which are presented in accordance with GAAP. These non-GAAP financial measures include EBITDA, adjusted

bllnlogoa.jpg
EBITDA and free cash flow. By excluding the impact of certain items that we believe do not directly reflect our underlying operations, we are of the opinion that EBITDA, adjusted EBITDA and free cash flow provide meaningful supplemental information regarding our performance. Accordingly, we believe these non-GAAP financial measures are useful to investors and others because they allow for additional information with respect to financial measures used by management in its financial and operational decision-making and forecasting. These metrics also provide investors and other users of our financial information with additional tools to compare business performance across companies and periods, while eliminating the effects of items that may vary for different companies for reasons unrelated to core operating performance. However, there are a number of limitations related to the use of non-GAAP financial measures, and these non-GAAP measures should be considered in addition to, not as a substitute for or in isolation from, our financial results prepared in accordance with GAAP. Other companies, including companies in our industry, may calculate these non-GAAP financial measures differently or not at all, which reduces their usefulness as comparative measures. A reconciliation between GAAP and non-GAAP financial information is provided immediately following the financial tables. A reconciliation of the forecasted range for adjusted EBITDA for the full year 2026 is not included in this release due to the number of variables in the projected range and because we are currently unable to quantify accurately certain amounts that would be required to be included in the U.S. GAAP measure or the individual adjustments for such reconciliation.
EBITDA
We define EBITDA as net income (loss) adjusted for income taxes, interest income, interest expense, and depreciation and amortization expense.
Adjusted EBITDA
We define Adjusted EBITDA as net income (loss) adjusted for income taxes, interest income, interest expense, depreciation and amortization expense, and certain other items which include significant non-cash items events that are highly variable, significant in size, and that we do not believe are indicative of ongoing or future business operations, which include: stock-based compensation expense; change in fair value of term loan; and change in fair value of warrant liabilities.
Free Cash Flow
We define Free Cash Flow as net cash provided by operating activities adjusted for purchases of property and equipment.
