SERA PROGNOSTICS REPORTS FOURTH QUARTER AND FULL YEAR 2025 FINANCIAL RESULTS

SALT LAKE CITY, March 18, 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 fourth quarter and full year ended December 31, 2025.

Key 2025 and Recent Highlights:

Data Generation

• Published Landmark PRIME Study Demonstrating PreTRM® Blood Test Reduces Earliest Preterm Births and Newborn Complications: In January 2026, the PRIME Study, a randomized controlled trial of 5,018 women, was published in PREGNANCY, the peer-reviewed journal of the Society for Maternal-Fetal Medicine. Key findings from the Study include:
  • 56% and 32% fewer babies were born before 32 and 35 weeks, respectively
  • 20% fewer babies admitted to the NICU
  • Fewer health complications for newborns (20% reduction in odds of neonatal morbidity)
  • A NICU day was saved for every 4.2 patients screened
    
    
    
    
• 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 and recognizing the PreTRM approach aligned well with European healthcare systems.

Commercial Progress

• Expanded Commercial Engagement Across Wave 1 and Wave 2 Target States, Representing Nearly Half of U.S. Pregnancies: Advanced discussions underway with 10 commercial and Medicaid payers across 13 states for PreTRM program adoption, including the addition of a new partner program, bringing the total to two active partner programs.
  
  
  
  
• Expanded U.S. Commercial Organization: Added six field sales staff and Head of Access in anticipation of PRIME publication building momentum.
  
  
  
  
• Advanced Commercialization Preparations for the PreTRM Global Test Across European Markets: Regulatory progress underway toward CE marking and growing clinical validation, including recent European expert commentary recognizing PreTRM as a scalable, cost‑effective approach well suited to publicly funded healthcare systems.

Equity financing

• Completed Successful Follow-On Financing Extending Cash Runway Through 2028: In February 2025, Sera completed an underwritten public offering of common stock and pre-funded warrants, including the full exercise of the underwriters' option, generating approximately $57.5 million in gross proceeds before fees and expenses. Net proceeds will support commercial expansion in the U.S., advance preparations for potential EU expansion of the PreTRM Test and fund activities to drive broader market adoption.

Executive Leadership Team and Board of Directors Appointments

• Strengthened the Leadership Team and Board of Directors:
  
  
  
  
  • In October 2025, Dr. Tiffany Inglis was appointed as Sera's Chief Medical Officer. Dr. Inglis brings extensive clinical and payer-side leadership experience, including at Elevance Health and Carelon Health, where she advanced women's and children's health programs that improved care access and reduced costs. Her background makes her uniquely suited to support Sera's next phase of growth.
    
    
    
    
  • In May 2025, Lee Anderson joined Sera as Chief Commercial Officer. He brings over three decades of leadership across sales, marketing, customer service, and strategic accounts, with a proven ability to accelerate growth in healthcare markets. As Sera moves into full commercialization following the PRIME study publication, he will help drive broader adoption of the PreTRM Test.
    
    
    
    
  • In March 2025, Sera appointed Jeff Elliott to its Board of Directors. He brings extensive experience in corporate strategy, business operations, analytics, public company finance and commercializing molecular diagnostics. Mr. Elliott's unique background in growing diagnostics businesses is key to Sera in this critical stage of development.

"2025 marked a pivotal year for Sera as we moved from clinical validation to commercial execution," said Zhenya Lindgardt, Sera's President and Chief Executive Officer. "The publication of the landmark PRIME Study delivered strong, peer-reviewed evidence that the PreTRM® Test improves outcomes and reduces costs, creating a compelling value proposition for payers. During the year we expanded engagement across our target states, advanced active discussions with both commercial and Medicaid payers, and invested deliberately in leadership, access and infrastructure to support us as we scale. With a strengthened balance sheet, extending our runway through 2028, we enter 2026 focused on converting this foundation into broader adoption, payer coverage, and measurable impact for the families we serve."

About Sera Prognostics, Inc.

Sera Prognostics is a leading health diagnostics company dedicated to improving the lives of women and babies through precision pregnancy care. Sera's mission is to provide early, pivotal pregnancy information to improve the health of mothers and newborns, resulting in reductions in the costs of healthcare delivery. Sera has a robust pipeline of innovative diagnostic tests focused on the early prediction of preterm birth risk and other complications of pregnancy. Sera's precision medicine PreTRM® Test reports to a physician the individualized risk of spontaneous premature delivery in a pregnancy, enabling earlier proactive interventions in women with higher risk. Sera Prognostics is headquartered in Salt Lake City, Utah.

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.
