Capstone Extends Convertible Note Maturity to December 2027

Extension provides additional financial flexibility following retirement of approximately 87% of original convertible note principal.

NEW YORK--(BUSINESS WIRE)--Capstone Holding Corp. (NASDAQ: CAPS), a national, technology-enabled building products distribution platform, today announced an agreement with 3i, LP to extend the maturity of its remaining convertible note from October 22, 2026, to December 13, 2027.

The note, originally issued on October 22, 2025, has approximately $0.9 million in principal outstanding. Capstone has now retired approximately 87% of the original $6.8 million in principal issued under its two convertible notes with 3i.

Under the extension agreement, interest accruing after October 22, 2026, will be calculated solely on the outstanding principal balance at the note's existing 7% annual rate. 3i has also agreed not to enforce existing defaults prior to the new maturity date, with no default interest or late charges accruing on those defaults. The note's conversion rights remain unchanged.

“This agreement underscores our lending partner’s confidence in Capstone’s financial position and allows us to move forward with greater financial flexibility and a substantially reduced convertible debt balance,” said Matthew Lipman, Chief Executive Officer. “Our priority remains growing the business, improving profitability, and creating long-term value for our shareholders.”
