SAFE Agreements [Abstract]
SAFE Agreements	(10) SAFE Agreements First SAFE 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%. On April 21, 2024, 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. Second SAFE On February 15, 2024, the Company entered into a second SAFE (the “Second SAFE”) with the Purchaser, in connection with the Purchaser investing $3.5 million in the Company. The Second SAFE did not accrue interest. The Second SAFE was initially convertible into shares of the Company’s common stock upon the initial closing of an Equity Financing transaction at a per share conversion price which was equal to the lower of (i) the Second SAFE Price, and (ii) 80% of the price per share of the Company’s common stock sold in an Equity Financing transaction. If the Company consummated a change of control prior to the termination of the Second SAFE, the Purchaser would have been automatically entitled to receive an amount equal to the greater of (i) $3.5 million and (ii) the amount payable on the number of shares of the Company’s common stock equal to $3.5 million divided by the Liquidity Price, subject to certain adjustments as set forth in the Second SAFE. 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%. On April 21, 2024, the Company entered into an amendment (“Second SAFE Amendment”) that converted the Second SAFE investment of $3.5 million into 9,722,222 shares of the Company’s common stock based on a conversion price of $0.36 per share, defined in the Second 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 Second SAFE Agreement of $3.5 million, a credit to Additional paid-in-capital of $4.4 million and recognized expense of $0.9 million within Other expense, net in its unaudited condensed consolidated statement of operations in the Company’s second fiscal quarter ended June 30, 2024. Third SAFE On May 13, 2024, the Company entered into a third SAFE (the “Third SAFE”) with the Purchaser, in connection with the Purchaser investing $1.0 million in the Company. The Third SAFE is convertible into shares of the Company’s common stock upon the initial closing of a bona fide transaction or series of transactions with the principal purpose of raising capital, pursuant to which the Company issues and sells shares of its common stock in an Equity Financing transaction, at a per share conversion price which is equal to 50% of the price per share of the Company’s common stock sold in an Equity Financing. If the Company consummates a change of control prior to the termination of the Third SAFE, the Purchaser will be automatically entitled to receive a portion of the proceeds of such liquidity event equal to $1.0 million, subject to certain adjustments as set forth in the Third SAFE. The Third SAFE is convertible into a maximum of 2,750,000 shares of the Company’s common stock, assuming a per share conversion price of $0.275, which is the product of (i) $0.55, the closing price of the Company’s common stock on May 13, 2024, multiplied by (ii) 50%. Given that the Third SAFE may be settled in cash or a variable number of shares, the Company has accounted for the instrument as a liability at its fair value. The estimated fair value of the Third SAFE was $0.5 million and $0.4 million as of September 28, 2025 and December 29, 2024, based upon the assumptions disclosed in Note 4 – Fair Value Measurements. The change in the fair value of the Third SAFE is recorded within Other expense, net in the accompanying condensed consolidated statements of operations and comprehensive loss. The change in the fair value of the Third SAFE was expense of $0.1 million and $0.9 million in the thirteen week periods ended September 28, 2025 and September 29, 2024, respectively. The change in the fair value of the Third SAFE was expense of $0.1 million and $0.9 million in the thirty-nine week periods ended September 28, 2025 and September 29, 2024, respectively.
