POSITRON CORP (POSC) entered into a Line of Credit Agreement with affiliated investor George Ortiz on August 13, 2026. The facility provides a maximum aggregate principal of $2,000,000, with the company able to draw at its discretion, subject to a $500,000 per-calendar-quarter cap and a $50,000 minimum draw. Amounts repaid may be reborrowed within these limits.
The outstanding principal bears interest at a fixed 12% per annum, payable quarterly in arrears. For the first 12 months (the “Interest-Only Period”), only interest is due; during the following 12 months, both principal and interest are payable. All advances are due August 13, 2028, with optional prepayment at any time without penalty. Events of default include non-payment, covenant breaches, insolvency, and material adverse events, after which default interest of 18% per annum (or the legal maximum) may apply.
As additional consideration, Positron issued Ortiz warrants for 300,000 common shares at an exercise price of $1.50 per share, expiring December 31, 2030. If the company defaults on interest or principal payments when due, the warrant exercise price automatically reprices to $1.00 per share.
Positron Corporation disclosed that on December 23, 2025 it entered into a Subscription Agreement with a single investor to sell 1,333,333 shares of its common stock for an aggregate purchase price of $2,000,000. The transaction was completed without the use of a placement agent or finder, meaning the company dealt directly with the investor.
The shares were issued in a private transaction not registered under the Securities Act of 1933, relying on the Regulation S exemption. This issuance represents new equity capital for Positron and results in additional common shares outstanding. The company also filed the Subscription Agreement and a related press release as exhibits.
Positron Corporation reports a change in its independent auditor. Freed Maxick P.C. resigned as the company’s independent registered public accounting firm effective October 31, 2025. On December 10, 2025, the company appointed Salberg & Company, P.A. as its new independent registered public accounting firm.
Salberg has been engaged to audit Positron Corporation’s financial statements for the year ended December 31, 2025 and to review interim financial statements for the quarters ended March 31, 2026, June 30, 2026, and September 30, 2026. The company states that during the two most recent fiscal years and through December 10, 2025, it did not consult with Salberg on the application of accounting principles, the type of audit opinion that might be issued, or on any matter involving a “disagreement” or “reportable event” as defined in SEC rules.
