Item 4. | Purpose of Transaction | |
Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following:
On July 8 and 9, 2025, V3 sold an aggregate of 1,200,000 shares of Common Stock on the open market at an average price of $6.13 per share. These shares represent 2.6% of V3's direct holdings of Common Stock and the sales are part of V3 and Mr. Vavilov's previously disclosed, disciplined, long-term strategy to support personal initiatives for diversification and philanthropy. As of the date of this Amendment No. 11, and as a non-insider shareholder with no involvement in management or representation on the Issuer's board of directors, V3 and Mr. Vavilov are currently committed to a careful, gradual approach of selling on the open market from time to time, with a threshold of not exceeding 5% of the Issuer's average daily trading volume on any given day. The timing and quantity of future sales, if any, will depend on market conditions, the trading price of the Common Stock, and its volume. This disciplined approach reflects V3 and Mr. Vavilov's confidence in the Issuer's long-term growth and stability, and these sales are not indicative of any current change in V3 and Mr. Vavilov's outlook on the Issuer's potential. | ||
