Biocept Reports First Quarter 2023 Financial Results

SAN DIEGO (May 10, 2023) – Biocept, Inc. (Nasdaq: BIOC), a leading provider of molecular diagnostic assays, products and services, reports financial results for the three months ended March 31, 2023 and provides a business update.

“I’m exceptionally pleased with the progress being made with our FORESEE clinical trial, which is specifically designed to generate evidence of CNSide^™’s clinical utility to support adoption into clinical care guidelines and further broaden physician use. Trial enrollment is running well in line with our plan, and we’ve now activated clinical sites in Dallas, Los Angeles and the San Francisco Bay Area,” said Samuel D. Riccitelli, Biocept’s Chairman, and interim President and CEO. “In our quest to gain further physician and payor acceptance, we submitted an article to a peer-reviewed journal describing our assay, its attributes, and the work to demonstrate CNSide’s performance validity. We expect two additional manuscripts to be submitted for peer-review later this year by leading neuro-oncologists detailing their experience with CNSide through case study reports.

“We have begun requiring all new customers to sign lab service agreements prior to commencing use of our assay to facilitate fair and turnkey reimbursement for CNSide testing, and we are negotiating similar agreements with current customers. Nearly half of our existing clients have engaged with us on this matter and although the program has yielded only two signed agreements to date, we are hopeful this will allow us to continue to offer CNSide in a more cost-effective manner going forward,” he added. “Additionally, our cost-control measures put in place over the past year continued to drive down expenses.

“We look forward to providing a progress report and updates on the FORESEE trial when we resume holding quarterly investor calls with reporting of second quarter financial results in mid-August,” Mr. Riccitelli concluded.

First Quarter Financial Results

Net revenues for the first quarter of 2023 were $0.7 million, compared with $19.9 million for the first quarter of 2022, with the decline due to lower RT-PCR COVID-19 testing volume. In February 2023 the Company ceased providing COVID-19 testing services. The number of commercial accessions delivered for the first quarters of 2023 and 2022 were 3,085 and 153,056, respectively.

Cost of revenues for the first quarter of 2023 was $3.0 million, compared with $10.3 million for the first quarter of 2022, with the decrease primarily associated with the cessation of COVID-19 testing services.

Research and development expenses for the first quarter of 2023 were $1.0 million, compared with $1.8 million for the first quarter of 2022, with the decrease primarily due to a reduction in headcount and lower purchases of materials and supplies.

General and administrative expenses for the first quarter of 2023 were $3.0 million, compared with $6.3 million for the first quarter of 2022. The decrease was primarily due to lower legal and outside service expenses in the 2023 quarter, and separation agreements with former executive management in the 2022 quarter.

Sales and marketing expenses for the first quarter of 2023 were $0.7 million, compared with $3.7 million for the first quarter of 2022, with the decrease primarily due to fewer sales representatives, lower commission expense and a decrease in outside services expenses.

Net loss attributable to common stockholders for the first quarter of 2023 was $7.1 million, or $0.41 per share, compared with a net loss attributable to common stockholders for the first quarter of 2022 of $2.2 million, or $0.13 per share.

Biocept reported cash of $6.8 million as of March 31, 2023, compared with $12.9 million as of December 31, 2022.
