J. Daniel McCranie and Devin Whatley (the “Affiliate Investors”), pursuant to which the Company agreed to issue
and sell 103,109,005 shares of the Company’s common stock, $0.0001 par value per share (the “Shares”),
in separately negotiated private placement transactions (the “Private Placement”) for gross proceeds of approximately
$26.2 million, including amounts funded under simple agreements for future equity. The purchase price per Share payable under the Purchase Agreements is $0.2541, which equaled the Nasdaq Official
Closing Price of the Common Stock on September 2, 2026. The Company intends to use the proceeds of the Private Placement for working capital
and general corporate purposes.
The Private Placement is expected to close on
September 4, 2026, subject to the satisfaction of the closing conditions set forth in the Purchase Agreements.
Pursuant to the Purchase Agreements, the Company
agreed to prepare and file a resale registration statement for the Shares with the Securities and Exchange Commission on or before October

of this type.

Act”), and/or Rule 506 of Regulation D promulgated thereunder.
This Current Report on Form 8-K does not constitute
an offer to sell or a solicitation of an offer to buy the Shares, nor shall there be any sale of the Shares in any jurisdiction in which
such offer, solicitation or sale would be unlawful.
The Shares have not been registered under the
Securities Act and may not be offered or sold in the United States absent registration or an applicable exemption from registration requirements.
