Subsequent Events [Abstract]
Subsequent Events	Note 17. Subsequent Events On January 11, 2024, the Company announced a reduction in its workforce that affected approximately 15% of its employees at that time. The Company estimates that it will incur approximately $1.2 million of costs in connection with the reduction in workforce related to severance pay and other termination benefits. The Company expects the majority of the costs to be incurred and payments made during the first quarter of 2024. Total annual cost savings from the reduction in workforce are estimated at $6.4 million. On January 16, 2024, the board of directors of the Company approved a stock option repricing (the Option Repricing), which was effective on March 14, 2024 (the Repricing Date). The Option Repricing applies to outstanding options to purchase shares of common stock of the Company (the Common Stock) that, as of the Repricing Date, are held by employees and certain non-employee directors of the Company (the Outstanding Options), and were granted under the Company’s 2016 Plan, 2020 Plan, and 2021 Plan (collectively, the Plans). As of the Repricing Date, all Outstanding Options were repriced such that the exercise price per share for such Outstanding Options will be reduced to the Fair Market Value (as defined in the Plans) of the Common Stock on the Repricing Date (the New Price), effective as of the Price Reduction Date (as defined below), provided that the holder remains employed by the Company or continues to serve as a member of the board of directors through such date. The Price Reduction Date is the earliest to occur of (i) September 14, 2025, (ii) the date of the holder’s termination of employment or service with the Company due to (x) a termination by the Company without cause or (y) the holder’s resignation for good reason, or (iii) the date on which a change in control of the Company occurs. For the avoidance of doubt, other than in event of a change in control, the reduced exercise price only applies to exercises that occur on or after the Price Reduction Date and if a holder’s employment by or service to the Company has not ended (other than due to a termination by the Company without cause or a resignation for good reason) prior to the Price Reduction Date. If a holder exercises any of his or her Repriced Options (as defined below) prior to the Price Reduction Date, the original (unmodified, current) exercise price will continue to apply. In addition, in the event that an Outstanding Option has an exercise price that is less than the New Price, such Outstanding Option will not be repriced as part of the Option Repricing. The Outstanding Options that are repriced on the Repricing Date (the Repriced Options) will include the Outstanding Options held by our employees (including our executive officers) and certain non-employee directors. There will be no changes to the number of shares, the vesting schedule, or the expiration date of the Repriced Options. The Option Repricing will result in additional share-based compensation expense that will be recognized in the Company’s statements of operations in future periods; however, the amount of additional share-based compensation expense and the periods over which it will be recognized have not yet been determined. On March 8, 2024, the Company entered into limited waivers and amendments (collectively Amendment No. 5, or, as amended, the Amended Credit Agreement) which includes a waiver from MidCap of the revenue covenant violations for each of the periods ending November 30, 2023 and January 31, 2024. Amendment No. 5 also reduced these requirements for future periods up to and including for the twelve months ending December 31, 2024, from $42 million to $34 million. Amendment No. 5 also removed those requirements for the periods ending January 31, 2025 through December 31, 2025, instead requiring that for each applicable twelve-month period ending after December 31, 2024, the Company’s minimum net revenue requirement will be determined by MidCap in its reasonable discretion in consultation with the Company’s senior management and based on financial statements and projections delivered to MidCap in accordance with the financial reporting requirements in the Amended Credit Agreement, so long as the minimum net revenue requirements for those periods shall not be less than the greater of (x) the applicable minimum net revenue requirement for the twelve-month period ending on the last day of the immediately preceding month and (y) $34.0 million. In addition, Amendment No. 5 also removed the advance rate for finished goods inventory in the determination of the borrowing base for the Revolving Loan and increased the minimum cash requirement from $9.0 million to $10.0 million. Finally, Amendment No. 5 conditions the next borrowing under the Revolving Loan on the Company achieving net revenue for the preceding twelve-month period of at least $38.0 million down from $45.0 million. The Amended Credit Agreement is unmodified in all other material respects. On March 8, 2024, as a condition to the effectiveness of Amendment No. 5, the Company issued to MidCap Funding XXVII a warrant to purchase up to an aggregate of 125,000 shares (the Common Warrant) of Common Stock with an exercise price of $2.9934 per share, subject to adjustment as provided therein. The Common Warrant is exercisable immediately, and will expire on the earlier to occur of the (i) expiration of the Common Warrant pursuant to Section 1.6 thereof, or (ii) tenth (10th) anniversary of the Issue Date (as defined therein). The exercise price and number of shares of Common Stock issuable upon the exercise of the Common Warrant will be subject to adjustment in the event of any stock dividend, stock split, recapitalization, reorganization or similar transaction, as described in the Common Warrant. MidCap may exercise the Common Warrant for cash or by means of a “cashless exercise.
