Previous wording

We have incurred net losses each year since our inception in 2008. To date, we have financed our operations primarily through private placements of our equity and debt securities, bank loans, the sale and issuance of Class A common stock in our IPO, and the sale and issuance of Class A common stock and pre-funded warrants in the February 2025 Offering. Our net loss for the three months ended March 31, 2026 and 2025 was $8.4 million and $8.2 million, respectively. As of March 31, 2026, we had an accumulated deficit of $320.1 million. Our losses may continue to increase in the future as we continue to devote a substantial portion of our resources to efforts to increase the adoption of, and reimbursement for, the PreTRM test, make improvements to this product, and research, develop and commercialize new products and services.

Previous wording

We currently receive substantially all of our revenues from the sales of the PreTRM test and expect to continue to receive revenue from sales of the PreTRM test and our other pipeline products and services in the future. It is possible that we will not generate sufficient revenue from the sales of any of our products and services to cover our costs, including research and development expenses related to furthering our product pipeline, and achieve or sustain profitability. A significant element of our business strategy is to increase and maintain our in-network coverage with third-party payers. However, third-party payers, such as commercial insurers and government health care programs, may decide not to reimburse for the PreTRM test or other tests we may develop, may not reimburse for uses of the PreTRM test or our other tests for the pregnant patient population, or may set the amounts of such reimbursements at prices that do not allow us to cover our expenses. Many third-party payers currently either have negative coverage determinations or otherwise do not reimburse for low-risk patient preterm birth screening tests. State Medicaid programs currently do not reimburse for our tests; third-party payers are increasingly requiring that prior authorization be obtained prior to conducting testing as a condition to reimbursing for it, which may reduce and/or delay the reimbursement amounts.

The ability of governmental agencies to meet their mandates can be affected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel, and statutory, regulatory, and policy changes. Government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. For example, over the last several years, the U.S. government has shut down several times, most recently in January 2026, resulting in certain regulatory agencies such as the FDA, CMS, and the SEC furloughing critical employees and suspending critical activities. Additionally, the Trump Administration has implemented a large-scale reduction of the federal government workforce as well as major organizational changes and consolidating throughout the executive branch since assuming office in January 2025. The impact of mass layoffs at governmental offices with which we interact is unclear at this time, and organizational changes remain fluid. If a prolonged government shutdown or slowdown occurs, or a significant reduction in force makes it difficult for offices with which we interact to respond timely, it could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Under the Trump Administration and the 119 th Congress, there remains uncertainty around the future of the ACA and other health care legislation, and in particular the impact to reimbursement levels and the number of insured individuals. The One Big Beautiful Bill Act, or OBBBA, approved by Congress and signed into law on July 4, 2025, included changes to existing laws that may have significant implications for health care providers. In particular, the OBBBA is projected to result in substantial reductions in federal spending on the Medicaid program over the next decade. Health care funding experts estimate that the cuts during that period will exceed $1 trillion. The OBBBA also made changes to the state insurance exchanges formed under Patient Protection and Affordable Care Act, as amended by the ACA. The Congressional Budget Office estimates the OBBBA could result in millions of additional uninsured people by 2034. These and other changes may negatively affect the purchasing decisions of our customers.

We have registered on Form S-8 all shares of common stock that are issuable under our existing equity compensation plan, including the 2011 Employee, Director and Consultant Equity Incentive Plan, as amended, or the 2011 Plan, which expired in 2021, the 2021 Equity Incentive Plan, or the 2021 Plan, and the 2021 Employee Stock Purchase Plan, or the 2021 ESPP, as well as the shares of common stock underlying option awards outstanding under the 2011 Plan. Additionally, the number of shares of our Class A common stock reserved for issuance under our 2021 Equity Plan automatically increases on January 1 of each year, beginning on January 1, 2022, by 4% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our board of directors or compensation committee. Furthermore, the number of shares of our Class A common stock reserved for issuance under our 2021 ESPP automatically increases on January 1 of each year, beginning on January 1, 2022, by 1% of the total number of shares of our capital stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by our board of directors or compensation committee. Unless our board of directors elects not to increase the number of shares available for future grant each year, our stockholders may experience additional dilution. As a consequence, these shares can be freely sold in the public market upon issuance, subject to volume limitations applicable to affiliates.

We are required to disclose changes made in our internal controls and procedures on a quarterly basis and our management are required to assess the effectiveness of these controls annually. However, as long as we are an EGC and a smaller reporting company with revenues under $100 million, our independent registered public accounting firm is not required to attest to the effectiveness of our internal controls over financial reporting pursuant to Section 404 of SOX. We could be an EGC until December 31, 2026, and a smaller reporting company with revenues under $100 million beyond December 31, 2026. An independent assessment of the effectiveness of our internal controls over financial reporting could detect problems that our management’s assessment might not. Undetected material weaknesses in our internal controls over financial reporting could lead to restatements of our financial statements and require us to incur the expense of remediation.
