# SERA PROGNOSTICS REPORTS FOURTH QUARTER 2025 FINANCIAL RESULTS
**Salt Lake City** – March 18, 2026 – 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:**

**<u>Data Generation</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;•**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:

o56% and 32% fewer babies were born before 32 and 35 weeks, respectively

o20% fewer babies admitted to the NICU

oFewer health complications for newborns (20% reduction in odds of neonatal morbidity)

oA NICU day was saved for every 4.2 patients screened

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

**<u>Commercial Progress</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Expanded U.S. Commercial Organization:** Added six field sales staff and Head of Access in anticipation of PRIME publication building momentum.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

**<u>Equity financing</u>** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**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.

**<u>Executive Leadership Team and Board of Directors Appointments</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Strengthened the Leadership Team and Board of Directors:**

oIn 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.

oIn 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.

oIn 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."

**Fourth Quarter 2025 Financial Results**

Fourth quarter 2025 revenue was $10,000 compared to $24,000 for the fourth quarter of 2024.

Total operating expenses were $9.0 million, compared to $9.4 million for the same period in 2024.

Research and development expenses for the fourth quarter of 2025 were $3.2 million, compared to $3.1 million for the fourth quarter of 2024.

Selling, general and administrative expenses for the fourth quarter of 2025 were $5.7 million, compared to $6.3 million for the prior-year period as Sera continued to carefully invest in targeted commercial activities and strategic headcount additions, while building market awareness in preparation for the publication of PRIME study data.

------

![img88505028_0.jpg](img88505028_0.jpg)

Net loss for the quarter was $7.9 million, compared to $8.6 million for the fourth quarter of 2024 as the Company continued its focus on managing our capital resources ahead of expected revenue expansion in the future.

**Full Year 2025 Financial Results**

Total full year 2025 revenue was $81,000 compared to $77,000 for full year 2024.

Total operating expenses were $36.6 million, compared to $36.7 million for the same period in 2024.

Research and development expenses for 2025 were $13.2 million, down from $14.7 million for the prior year primarily due to lower clinical study costs following the completion of the pivotal PRIME study and as the Company shifts toward commercialization.

Selling, general and administrative expenses for 2025 were $23.3 million, up from $21.9 million for the prior-year period as Sera continued to carefully invest in targeted commercial activities and strategic headcount additions, while building market awareness ahead of the publication of PRIME study data in January 2026.

Net loss for 2025 was $31.9 million and down from $32.9 million for 2024 as the Company continued its focus on managing our capital resources ahead of expected revenue expansion in the future.

As of December 31, 2025, the Company had cash, cash equivalents, and available-for-sale securities of approximately $95.8 million, which Sera expects to fund the company across significant adoption and commercial milestones through 2028.

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.
