SERA PROGNOSTICS REPORTS FIRST QUARTER 2023 FINANCIAL RESULTS

SALT LAKE CITY, May 10, 2023 /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 of 2023 ended March 31, 2023.

Recent Highlights:

• Announced positive top-line results from the AVERT PRETERM TRIAL (Serum Assessment of Preterm Birth Outcomes Compared to Historical Controls).
• Increases in physician orders Q1 2023 vs. Q1 2022, as more physicians deploy the PreTRM® test-and-treat strategy.
• PRIME study subject enrollment continues, with the interim look analysis anticipated to take place by year-end.
• Anticipate submission this summer of new compelling data for scientific review for publication.

"The exciting AVERT PRETERM TRIAL topline results announced in February are a part of Sera's growing strong foundation of compelling data demonstrating the value of the PreTRM test-and-treat strategy," said Gregory C. Critchfield, MD, MS, Chairman and CEO of Sera Prognostics. "We see the publication of these data as a driver to enable physicians and healthcare institutions to substantively address the serious challenges of preterm birth. While implementation will take time, we anticipate that the availability of additional clinical utility information during this year, should serve as an additional catalyst to help us expand the use of our PreTRM Test and to increase revenue."

First Quarter 2023 Financial Results

First quarter 2023 revenue of $100,000 compared to $38,000 for the same period of 2022.

Total operating expenses were $11.4 million, down from $12.3 million for the first quarter of 2022.

Research and development expenses for the first quarter of 2023 were $4.1 million compared to $3.3 million for the first quarter of 2022 due primarily to increased clinical study costs.

Selling, general and administrative expenses for the first quarter of 2023 were $7.3 million, down significantly from $9.0 million for the first quarter of 2022 due primarily to steps we took prior to year-end 2022 to streamline sales operations, and better focus our commercial strategy in response to market dynamics.

Net loss for the first quarter of 2023 was $10.6 million compared to $12.2 million for the same quarter a year ago.

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.
