Exhibit 99.1

Salt Lake City – November 8, 2023 – 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 third quarter of 2023 ended September 30, 2023.
Recent Highlights:
Sera Board of Directors approved permanent President and CEO and CFO appointments for Zhenya Lindgardt and Austin Aerts, respectively.
Management team completed planned cost reduction activities to extend cash runway through most of 2027.
Scaling our care coordination offering and providing it for institutional customers for women identified as high-risk for preterm birth using our PreTRM test. Sera believes this service offering to patients can improve test adoption by physicians by providing the availability of care coordination to their high-risk patients.
Moved new high-low risk predictor product into next phase of market research in preparation for clinical validation.
Shared findings from AVERT clinical trial highlighting PreTRM test’s impact of driving 2.5-week improvement in gestational age of infants most at risk for early delivery, 18% reduction in severe neonatal morbidity and mortality, and 28-day reduction in Neonatal Intensive Care Unit length of stay for infants born before 32 weeks. We have begun actively sharing the data from AVERT with potential institutional customers.
“We continue to lay the groundwork for a reinvigorated commercial focus designed to cost-effectively target increased test adoption through institutional customer focus, care coordination program, and are exploring potential product and partnership pathways to expand our commercial revenue,” said Zhenya Lindgardt, President and CEO of Sera Prognostics. “At the same time, we are focused on continuing to share data that supports the value of early, pivotal pregnancy information powered by Sera that, coupled with interventions for high-risk patients, can lead to better health for mothers and newborns at reduced healthcare costs.”
Third Quarter 2023 Financial Results
Third quarter 2023 revenue of $42,000 compared to $87,000 for the same period of 2022.
Total operating expenses were $8.2 million, down significantly from $11.3 million for the third quarter of 2022.


Research and development expenses for the third quarter of 2023 were $3.5 million compared to $4.2 million for the third quarter of 2022 due primarily to lower clinical study costs.
Selling, general and administrative expenses for the third quarter of 2023 were $4.6 million, down significantly from $7.0 million for the third quarter of 2022 due primarily to steps we took prior to year-end 2022 and more recently to streamline commercial operations, better focus our commercial strategy in response to market dynamics and align our administrative costs to match our current level of operations.
Net loss for the third quarter of 2023 was $7.2 million compared to $10.7 million for the same quarter a year ago.
As of September 30, 2023, the Company had cash, cash equivalents, and available-for-sale securities of approximately $85.0 million.

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.

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 2022 March of Dimes Report Card shows that, for the last four consecutive years, more than one in ten infants is born prematurely. 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.
