Biodesix, Inc. Announces One-for-Twenty Reverse Stock Split Effective September 15, 2025

LOUISVILLE, Colo., Sept. 11, 2025 (GLOBE NEWSWIRE) -- Biodesix, Inc. (Nasdaq: BDSX) (“Biodesix” or the “Company”), a leader in personalized diagnostics, today announced a one-for-twenty reverse stock split (the “Reverse Stock Split”) of the Company’s common stock, par value $0.001, which will become effective at 12:01 a.m. Eastern Time on Monday, September 15, 2025. The Company’s common stock will continue to trade under Biodesix’s existing trading symbol, BDSX, on the Nasdaq Global Market (“Nasdaq”) on a split-adjusted basis when the market opens on Monday, September 15, 2025, with the new CUSIP number 09075X207.

The Reverse Stock Split was approved by Biodesix’s stockholders at the annual meeting held on May 20, 2025, with the final ratio subsequently determined by the Company’s board of directors. As a result of the Reverse Stock Split, every 20 shares of the Company’s pre-split common stock issued and outstanding will be automatically reclassified into one new share of the Company’s common stock. The Reverse Stock Split will reduce the number of shares of common stock issued and outstanding from approximately 156 million to approximately 8 million, subject to adjustment due to the payment of cash in lieu of fractional shares. There will be no change to the number of authorized shares or the par value per share.

The Reverse Stock Split will affect all stockholders uniformly and will not alter any stockholder’s percentage ownership interest, except to the extent that the Reverse Stock Split results in fractional share amounts. Stockholders who would otherwise hold a fractional share of common stock will receive a cash payment in lieu of such fractional share.

As of the effective date of the Reverse Stock Split, the number of shares of common stock available for issuance under the Company’s equity incentive plans and issuable upon the exercise of stock options, restricted stock units and warrants outstanding immediately prior to the Reverse Stock Split will be proportionately adjusted. The exercise prices of the Company’s outstanding options and warrants will be proportionately adjusted.

Computershare Trust Company, N.A. (“Computershare”) is acting as the transfer agent for the Reverse Stock Split. Computershare will provide notice to stockholders of record, issue post-split shares in paperless “book-entry” form, and hold the shares in an account set up for each respective stockholder without the need for stockholder action. Registered stockholders holding pre-split shares of the Company's common stock are not required to take any action to receive post-split shares. Any stockholders with certificated shares of the Company’s common stock will receive a letter of transmittal from Computershare with instructions on how to surrender certificates representing pre-split shares, which will become book-entry shares post-Reverse Stock Split. Stockholders should not send in their post-Reverse Stock Split certificates until they receive a letter of transmittal (which will also include a lost securities affidavit with respect to any certificate that cannot be located) from Computershare. In order to receive post-split shares of the Company’s common stock, cash payments in lieu of fractional shares, and any future dividends or distributions the Company may declare with a record date after the effective date of the Reverse Stock Split, stockholders must return these certificated shares of common stock or a lost securities affidavit. Stockholders owning shares in "street name" or via a broker, bank, trust or other nominee will have their positions automatically adjusted to reflect the Reverse Stock Split, subject to the particular processes of such broker, bank, trust or other nominee, and will not be required to take any action in connection with the Reverse Stock Split.

Additional information regarding the Reverse Stock Split is available in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on April 28, 2025, a copy of which is available at www.sec.gov and on the Company's website.
