SERA PROGNOSTICS REPORTS FIRST QUARTER 2026 FINANCIAL RESULTS

SALT LAKE CITY, May 6, 2026 /PRNewswire/ -- Sera Prognostics Inc., The Pregnancy Company® (Nasdaq: SERA), focused on improving maternal and neonatal health by providing innovative pregnancy biomarker information to doctors and patients, today announced financial results for the first quarter ended March 31, 2026.

Key First Quarter and Recent Highlights:

• Published Landmark PRIME Randomized Trial: Study in 5,018 women showing the PreTRM® test reduced early preterm births (–56% <32 weeks; –32% <35 weeks), NICU admissions (–20%), and neonatal morbidity (-20%), with one NICU day saved per 4.2 patients screened.
• Expanded European Evidence Base with Two Peer-Reviewed Publications:
  • PREPARE Survey Accepted for Publication in The Journal of Women's Health: In March, results from the Pregnancy Research on European Women's Preterm Birth Awareness, Risk and Education (PREPARE) survey were accepted for publication evaluating preterm birth awareness, risk perception, and education across five countries. Findings identified a meaningful gap between perceived awareness and actionable understanding of preterm birth risk, underscoring the need for earlier and more standardized risk communication, an area PreTRM® testing is designed to address. The live publication is expected in May.
  • European Expert Commentary on the PRIME Trial Published in The Journal of Maternal-Fetal & Neonatal Medicine: In March, expert commentary highlighted that current European preterm birth prevention strategies fail to identify most women who deliver preterm. They recognized that the PreTRM approach better aligns with existing European healthcare systems.
• Commercial Progress: Launched third partnership program expanding physician education and access to PreTRM. This program is expected to reach over 350 providers across three states. In parallel, we are now engaged in active discussions with 13 payers across 15 states, reflecting our strategy to deepen relationships within a focused set of target markets.
• Strong Presence Across Key Medical Meetings:
  • American College of Obstetricians and Gynecologists (ACOG) Annual Clinical and Scientific Meeting in May: Participation included a dedicated product theater and targeted engagement with clinicians to discuss evidence generation and clinical implementation of PreTRM.  
  • Society of Maternal-Fetal Medicine (SMFM) Annual Meeting in February: Highlighted key clinical evidence from PRIME study and engaged with maternal-fetal medicine specialists on PreTRM's role in risk stratification and early intervention. We also engaged with SMFM leadership to discuss the PRIME study outcomes.
• Continued Progress in Europe: Advancing toward CE marking with regulatory dossier preparation on track for mid‑year submission. Commercial readiness efforts are supported by ongoing clinical validation activities and engagement with European clinical and advisory stakeholders.
• Cash Runway Extended Through 2029: As part of the final phase of our transition from a clinical to a commercial organization, we completed a comprehensive business review to redirect investment from clinical activities toward commercialization and rightsized our operating model, resulting in a sustainable cost structure to support the company across significant adoption and commercialization milestones through 2029.

"In the first quarter, our primary focus was building awareness with clinicians and the broader stakeholder community as we continue the evolution from clinical stage to a commercial driven organization," said Zhenya Lindgardt, President and CEO of Sera Prognostics. "We made meaningful progress translating our expanding clinical foundation into commercial readiness, supported by growing peer reviewed validation in Europe, increasing clinician engagement, expanded education and access through the launch of our third partnership program, and active discussions with 13 payers across 15 states. Our strong presence at SMFM and ACOG and continued progress toward CE marking underscore our focus on scaling in high‑value markets and driving adoption of the PreTRM® test."

"During the quarter, we advanced into the next phase of our evolution as a commercial organization through a comprehensive business review. As discussed in prior quarters, we redirected investment from clinical spend toward reimbursement driven commercialization while maintaining a sustainable cost structure," said Austin Aerts, Chief Financial Officer of Sera Prognostics. "These actions extended our cash runway by approximately one year, through 2029, providing the financial flexibility to fund the company through key adoption and commercial milestones."

About Preterm Birth

Preterm birth is defined as any birth before 37 weeks' gestation and is the leading cause of illness and death in newborns. The 2025 March of Dimes Report Card shows that, for the fourth consecutive year, the United States earned a D+ grade for preterm birth, making the longest stretch of the lowest grade in Report Card history. Prematurity is associated with a significantly increased risk of major long-term medical complications, including learning disabilities, cerebral palsy, chronic respiratory illness, intellectual disability, seizures, and vision and hearing loss, and can generate significant costs throughout the lives of affected children. The annual health care costs to manage short- and long-term complications of prematurity in the United States were estimated to be approximately $25 billion for 2016.

About the PreTRM® Test

The PreTRM® Test is the only broadly validated, commercially available blood-based biomarker test that provides an early, accurate and individualized risk prediction for spontaneous preterm birth in asymptomatic singleton pregnancies. The PreTRM® Test measures and analyzes proteins in the blood that are highly predictive of preterm birth. The PreTRM® Test permits physicians to identify, during the weeks 18 through 20 of pregnancy, which women are at increased risk for preterm birth and its complications, enabling more informed, personalized clinical decisions based on each woman's individual risk. The PreTRM® Test is ordered by a medical professional.
