Subsequent Events [Abstract]
Subsequent Events	Subsequent Events As described in Note B (Liquidity and Going Concern), the Company's $300.0 million senior secured term loan facility under its Credit and Guaranty Agreement with Silver Point Finance, LLC, as administrative agent (see Note G), requires the Company to maintain compliance with certain financial covenants, including a minimum liquidity covenant. The Company was in compliance with these covenants as of April 30, 2026. Subsequent to April 30, 2026, the Company failed to comply with these covenants, specifically the minimum liquidity covenant and the minimum collateral coverage ratio covenant. The Company obtained a series of short-term waivers from its lenders and, on June 19, 2026, entered into an amendment to the Credit and Guaranty Agreement (the "Amendment") that provides covenant relief for a limited period extending through early September 2026, which may be extended through November 2026 only if specified conditions are satisfied. The Amendment requires the Company to satisfy certain milestones during the relief period. In connection with the waivers and the Amendment, the Company incurred additional debt issuance costs of approximately $18.0 million, which were added to the outstanding principal balance under the Credit and Guaranty Agreement. If the Company fails to satisfy these milestones or the other conditions of the Amendment, or is unable to obtain further covenant relief, waivers or financing prior to the expiration of the relief period, the lenders would be entitled to exercise remedies under the Credit and Guaranty Agreement, including acceleration of the outstanding indebtedness. On June 3, 2026, the Board of Directors approved a retention program for senior management, including the named executive officers, and other key employees, consisting of cash retention awards and stock options intended to support operational stability during the Special Committee's evaluation of strategic alternatives. Cash retention awards were $1,200,000 to the Chief Executive Officer, $563,000 to the Chief Financial Officer, $531,000 to the Chief Operating Officer, and $300,000 to the Chief Accounting Officer. Each award must be repaid, on a post-tax basis, if the executive's employment ends before the earlier of a change in control or one year from the grant date, unless the termination is without cause, for good reason, or due to death or disability. The stock options were granted at an exercise price equal to the closing stock price on the grant date and vest in four equal annual installments. A portion were issued as contingent options requiring stockholder approval of additional shares under the 2024 Equity Incentive Plan at the 2026 Annual Meeting; if approval is not obtained, those options will be voided.
