Description of simple agreement for future equity terms and conditions |  |  |  | On January 31, 2024, the Company entered into a Simple Agreement for Future Equity (“SAFE”) (the “First SAFE”) with the Rodgers Massey Freedom and Free Markets Charitable Trust (the “Purchaser”), a related party, affiliated with Thurman J. Rodgers, the Company’s Chief Executive Officer and a director, in connection with the Purchaser investing $1.5 million in the Company. The First SAFE did not accrue interest. The First SAFE was initially convertible into shares of the Company’s common stock, par value $0.0001 per share, upon the closing of a bona fide transaction or series of transactions with the principal purpose of raising capital, pursuant to which the Company would have issued and sold shares of its common stock at a fixed valuation (an “Equity Financing”), at a per share conversion price which was equal to the lower of (i) (a) $53.54 million divided by (b) the Company’s capitalization immediately prior to such Equity Financing (such conversion price, the “SAFE Price”), and (ii) 80% of the price per share of its common stock sold in the Equity Financing. If the Company consummated a change of control prior to the termination of the First SAFE, the Purchaser would have been automatically entitled to receive a portion of the proceeds of such liquidity event equal to the greater of (i) $1.5 million and (ii) the amount payable on the number of shares of common stock equal to (a) $1.5 million divided by (b)(1) $53.54 million divided by (2) the Company’s capitalization immediately prior to such liquidity event (the “Liquidity Price”), subject to certain adjustments as set forth in the First SAFE. The First SAFE was convertible into a maximum of 1,431,297 shares of the Company’s common stock, assuming a per share conversion price of $1.05, which is the product of (i) $1.31, the closing price per share of the Company’s common stock on January 31, 2024, multiplied by (ii) 80%. |  |  |  |  |
Description of simple agreement for future equity amendment |  | the Company entered into an amendment (“First SAFE Amendment”) that converted the First SAFE investment of $1.5 million into 4,166,667 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the First SAFE Amendment as the product of (i) $0.45, the closing price of the Company’s common stock on April 19, 2024, multiplied by (ii) 80%. Upon conversion, the Company recorded a debit to the First SAFE Agreement of $1.5 million, a credit to Additional paid-in-capital of $1.9 million and recognized expense of $0.4 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024. |  |  |  |  |  |  |

The Second SAFE was convertible into a maximum of 3,707,627 shares of the Company’s common stock, assuming a per share conversion price of $0.94, which is the product of (i) $1.18, the closing per share price of its common stock on February 15, 2024, multiplied by (ii) 80%. |  |  |  |  |  |
