Biocept Announces Receipt of Deficiency Notice from Nasdaq Regarding Requirement to Timely Quarterly Report on Form 10-Q

Biocept, Inc. (Nasdaq: BIOC), a leading provider of molecular diagnostic assays, products and services, announces that it received a notice (the "Notice") on August 17, 2022 from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") advising Biocept that it was not in compliance with Nasdaq's continued listing requirements under the Nasdaq Listing Rule 5250(c)(1) (the "Rule") as a result of its failure to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2022 (the "Form 10-Q") in a timely manner.

The Rule requires listed companies to timely file all required periodic reports with the Securities and Exchange Commission (the "SEC"). Biocept previously reported in its Form 12b-25 filed with the SEC on August 16, 2022 that Biocept was unable to file the Form 10-Q within the prescribed time period as a result of ongoing accounting review, including the analysis of previously reported material weaknesses and matters related to the U.S. Health Resources Services Administration and its funding for reimbursement of COVID-19 testing services performed by Biocept.

Under Nasdaq rules, Biocept has 60 calendar days from the receipt of the Notice, or until October 17, 2022, to submit a plan to regain compliance with the Rule. If Nasdaq accepts Biocept's plan, Nasdaq may grant Biocept up to 180 calendar days from the due date of the Form 10-Q, or until February 13, 2023, to regain compliance.

In response to the Notice, Biocept intends to file the Form 10-Q as promptly as possible in order to regain compliance with the Rule. If Biocept does not submit the Form 10-Q by October 17, 2022, it intends to timely submit a plan to regain compliance with the Rule.
