Warrantsfinancial
"The Credit Fund directly holds (i) 56,866 shares of Common Stock and (ii) 375,000 warrants to purchase shares"
Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.
Beneficially ownregulatory
"The Warrants may not be exercised if the Reporting Persons would beneficially own more than 9.99% of the Issuer's outstanding shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

What stake does Perceptive Advisors report in Biodesix (BDSX)?
Perceptive Advisors and related entities report beneficial ownership of 483,694 shares, equal to 4.6% of common stock based on April 29, 2026 outstanding shares (10,108,580). This figure reflects shared voting and dispositive power.
How many warrants does the Credit Fund hold and can they be exercised?
The Credit Fund directly holds 375,000 warrants. The filing states the Warrants may not be exercised if exercise would result in beneficial ownership exceeding 9.99%, so exercise is currently subject to that ownership limitation.
How many shares does the Opportunity Fund directly hold in BDSX?
The Opportunity Fund directly holds 51,828 shares of common stock. This position is reported separately from the Credit Fund's holdings and contributes to the aggregated shared power reported by the Perceptive-related entities.
What is the total number of Biodesix shares outstanding used for the percentage calculation?
The ownership percentages in the filing are calculated using 10,108,580 shares outstanding as of April 29, 2026, according to the issuer's Form 10-Q cited in the filing's ownership disclosure.
Does the filing state whether the Perceptive group will sell or acquire more BDSX shares?
The filing reports current holdings and the warrant exercise limitation but does not state any planned sales or acquisitions. Any future transactions would require separate disclosure in later filings.
