1.	This percentage is based on a total of 113,627,715 Shares expected to be outstanding following the closing of the Issuer’s Concurrent Private Placement on April 9, 2024, as reported in the Issuer’s current report on Form 8-K filed with the SEC on April 9, 2024.

Item 1 of the Schedule 13D is hereby amended and supplemented as follows:

This Amendment No. 5 to Schedule 13D (“Amendment No. 5”) is being filed by the undersigned, pursuant to §240.13d-2(a), to amend and supplement the Schedule 13D filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 9, 2020, (the “Initial Schedule 13D”), as amended on January 28, 2022, on April 11, 2022, on November 23, 2022, and on August 11, 2023 (collectively, the “Schedule 13D”), with respect to the common stock, par value $0.001 per share (the “Shares”), of Biodesix, Inc. (the “Issuer” or the “Company”), whose principal executive offices are located at 919 West Dillon Rd., Louisville, Colorado 80027.

Item 3 of the Schedule 13D is hereby amended and supplemented as follows:

On April 5, 2024, the Issuer entered into securities purchase agreements (the “Securities Purchase Agreements”) with various investors, including the Trust (collectively, the “Investors”), for the issuance and sale by the Company of an aggregate of 760,857 shares of Series A Non-Voting Convertible Preferred Stock, par value $0.001 per share  (the “Series A Preferred Stock”) in an offering (the “Concurrent Private Placement”).  Pursuant to the terms of the Securities Purchase Agreements, the Company has agreed to submit to its stockholders the approval of the conversion of the Series A Preferred Stock into Shares in accordance with Nasdaq Stock Market Rules (the “Conversion Proposal”) at its 2024 annual meeting of stockholders. Following such approval of the Conversion Proposal, each share of Series A Preferred Stock will automatically convert into 40 Shares, subject to certain limitations. The Securities Purchase Agreements include customary representations, warranties and covenants by the parties to the agreement. Pursuant to the Securities Purchase Agreements, the Investors purchased the Series A Preferred Stock at a purchase price of $46.00 per share for an aggregate purchase price of approximately $35.0 million.

The Trust purchased 2,174 shares of Series A Preferred Stock in the Concurrent Private Placement, which will automatically convert into 86,960 Shares following approval of the Conversion Proposal, at a purchase price of $46.00 per share, for an aggregate purchase price of approximately $100,004, using Mr. Schuler’s personal funds.

The foregoing description of the Securities Purchase Agreements does not purport to be complete and is qualified in its entirety by reference to the full text of the Securities Purchase Agreements, the form of which is attached as Exhibit 5 to this Amendment No. 5 and is incorporated herein by reference.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

The response to Item 3 of this Amendment No. 5 is incorporated by reference herein.

Item 5(a) - (c) of the Schedule 13D is hereby amended and supplemented as follows:

(a, b) As of the date hereof, Mr. Schuler may be deemed to beneficially own, in the aggregate, 31,038,797 Shares, which represents approximately 27.2% of the Shares outstanding.

Mr. Schuler’s beneficial ownership consists of (1) 46,102 Shares that Mr. Schuler has the right to acquire upon exercise of options exercisable within 60 days of the date of this filing, (2) 284,973 Shares that Mr. Schuler has the right to acquire upon settlement of vested RSUs within 60 days of the date of this filing, and (3) 30,707,722 Shares held by the Trust, representing approximately 27.0% of the Shares outstanding. This amount excludes 86,960 Shares into which the 2,174 shares of Series A Preferred Stock will automatically convert following approval of the Conversion Proposal, because the Reporting Person does not have the right to acquire such Shares prior to stockholder approval of the Conversion Proposal.

Item 6 of the Schedule 13D is hereby amended and supplemented as follows:

The response to Item 3 of this Amendment No. 5 is incorporated by reference herein.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement, the form of which is attached as Exhibit 6 to this Amendment No. 5 and is incorporated herein by reference.

Except as otherwise set forth in this Amendment No. 5, there are no contracts, arrangements, understandings or relationships between the Reporting Persons and any other person with respect to any securities of the Issuer.

Item 7 of the Schedule 13D is hereby amended and supplemented as follows:
