Data Storage Corporation repurchased certain July 2021 warrants following a fundamental transaction. The company paid $2,049,388 to holders to buy back July 2021 Warrants that were exercisable for an aggregate of 858,750 shares of common stock.
The repurchase right was triggered by the consummation of the company’s sale of its cloud solutions business on September 11, 2025, and the window for holders to request repurchase expired on October 13, 2025. This action removes those specific warrants that could have been exercised for additional shares and results in a cash outflow equal to the stated repurchase amount.
