Depending on various factors, including but not limited to the Company’s financial position and strategic direction, price levels of the Common Stock, conditions in the securities markets, various laws and regulations applicable to the Company and companies in its industry and the Reporting Persons’ ownership in the Company, and general economic and industry conditions, the Reporting Persons may in the future take actions with respect to their investment in the Company as they deem appropriate, including changing their current intentions, with respect to any or all matters required to be disclosed herein. Without limiting the foregoing, and subject to any applicable limitations described in Item 6 below, the Reporting Persons may, from time to time, acquire or cause affiliates to acquire additional shares of Common Stock or other securities of the Company (including any combination or derivative thereof), dispose, or cause affiliates to dispose, of some or all of their Common Stock or other securities of the Company or continue to hold, or cause affiliates to hold, Common Stock or other securities of the Company.

In addition, the Reporting Persons have had and intend to continue having discussions, from time to time, with management and the board of directors of the Company, and may engage with other stockholders or securityholders of the Company and other relevant parties, or take other actions concerning, the Company’s business, lines of business, operations, strategy, plans and prospects; any extraordinary corporate transactions (including, but not limited to, a merger, reorganization or liquidation); sales of a material amount of assets or divestitures; a change in the board of directors or management; a material change in the Company’s capitalization, capital structure or dividend policies; other material changes in the Company’s business, lines of business, or corporate structure; or similar actions.

Except as set forth herein, or as would occur upon completion of any of the matters discussed herein, the Reporting Persons have no present plans, proposals or intentions which would result in or relate to any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Although the foregoing reflects activities presently contemplated by the Reporting Persons and each other individuals named in Item 2 with respect to the Company, the foregoing is subject to change at any time.

The information set forth under Items 3 and 6 is incorporated by reference herein.

Item 5.

Interest in Securities of the Issuer.

(a)-(b) The information contained on the cover pages of this Schedule 13D is incorporated herein by reference.

The Reporting Persons beneficially own in the aggregate 19,306,283 shares of Common Stock, which represents approximately 49.9% of the outstanding shares of Common Stock. All calculations of percentage ownership in this Schedule 13D are based on (i) 30,313,428 shares of Common Stock outstanding as of March 20, 2024 as disclosed in the Company’s Annual Report on Form 10-K filed with the SEC on April 1, 2024, plus (ii) shares issuable upon conversion of the 11.00% / 13.00% Convertible Notes held by the Reporting Persons, to the extent the 11.00% / 13.00% Convertible Notes are then convertible and the resulting shares are considered beneficially owned under applicable rules promulgated under the Exchange Act, plus (iii) shares underlying the Amended Warrant, the Second Common Stock Warrant, the September 2023 Pre-Funded Warrants, the September 2023 Warrants, the December 2023 Additional Warrants and the December 2023 Exchange Warrants, to the extent such warrants are then exercisable and the resulting shares are considered beneficially owned under applicable rules promulgated under the Exchange Act. Note that this does not give effect to the pending offer and sale by the Company of an aggregate 5,454,548 shares of Common Stock in a registered direct offering or the pending offer and sale of warrants to purchase up to 5,454,548 shares of Common Stock in a concurrent private placement as disclosed in the Company’s Current Report on Form 8-K filed with the SEC on April 2, 2024 (such offers and sales, the “March 2024 Offering”).

To the knowledge of the Reporting Persons, none of the Covered Persons directly owns any shares of Common Stock; provided, however, that because of each Covered Persons’ status as a director, executive officer, manager, member or partner of a Reporting Person, a Covered Person may be deemed to be the beneficial owner of the shares of Common Stock beneficially owned by such Reporting Person. Except to the extent of their pecuniary interest, each of the Covered Persons disclaims beneficial ownership of the shares of the Common Stock reported herein and the filing of this Schedule 13D shall not be construed as an admission that any such Covered Person is the beneficial owner of any securities covered by this statement.

(c) Except as described herein, none of the Reporting Persons or, to their knowledge, none of the Covered Persons, has had any transactions in the Common Stock during the past 60 days.

(d) Except as set forth herein, to the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any shares of Common Stock.

(e) Not applicable.

Item 6.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Fourth Amended and Restated Investors’ Rights Agreement

On August 27, 2019, Co-Invest LP, Acquisition LP and certain of their affiliates (the “Athyrium Parties”) entered into a fourth amended and restated investors’ rights agreement (the “Investors’ Rights Agreement”) with the Company and the other stockholders of the Company. The Investors’ Rights Agreement provides that the stockholders of the Company have certain registration rights described below. On November 12, 2019, in connection with its acquisition of the securities of the Company previously held by Acquisition LP, Acquisition 2 LP signed a joinder agreement to the Investors’ Rights Agreement and became one of the Athyrium Parties discussed below.

The registration rights described below will expire (i) with respect to any Athyrium Party, at the time such Athyrium Party can sell all of its registrable securities under Rule 144 or another similar exemption under the Securities Act of 1933, as amended (the “Securities Act” ), without limitation during a three-month period without registration, or (iii) upon termination of the Investors’ Rights Agreement.

The key registration rights under the Investors’ Rights Agreement are as follows:

•

Demand Registration Rights. At any time beginning 210 days after the effective date of the registration statement for the Company’s initial public offering, the holders of 50% or more of the registrable securities then outstanding may make a written request that the Company register all or a portion of their shares, subject to certain specified exceptions and conditions. The Company will then prepare and file a registration statement as requested, unless, in the good faith judgment of the Company’s board of directors, such registration would be seriously detrimental to the Company and its stockholders and filing should be deferred.

•

Piggyback Registration Rights. Subject to certain specified exceptions, if the Company proposes to register any of its securities under the Securities Act either for its own account or for the account of other stockholders, the holders of shares having registration rights are entitled to written notice and certain “piggyback” registration rights allowing them to include their shares in the Company’s registration statement. These registration rights are subject to specified conditions and limitations, including the right of the underwriters, in their sole discretion, to limit the number of shares included in any such offering under certain circumstances, but not below 15% of the total amount of securities included in such offering, unless all securities, other than the Company’s securities, are entirely excluded from the offering.

•

Form S-3 Registration Rights. At any time after the Company is qualified to file a registration statement on Form S-3, and subject to limitations and conditions, the holders of 50% or more of the registrable securities then outstanding are entitled to written notice of such registration and may make a written request that the Company prepare and file a registration statement on Form S-3 under the Securities Act covering their shares. The Company will then prepare and file the Form S-3 registration statement as requested, unless, in the good faith judgment of the Company’s board of directors, such registration would be seriously detrimental to the Company and its stockholders and filing should be deferred.

On November 10, 2020, the Company and the other stockholders party thereto entered into Amendment No. 1 to the Investors’ Rights Agreement in order to provide for the registration of the shares of Common Stock issued or issuable upon conversion of the Convertible Promissory Note.

On December 7, 2020, the Company and the other stockholders party thereto entered into Amendment No. 2 to the Investors’ Rights Agreement in order to provide for the registration of the shares of Common Stock issued or issuable upon conversion of the 7.25% Convertible Notes.

11.00% / 13.00% Convertible Notes

On December 19, 2023, the Company issued a new series of 11.00% / 13.00% Convertible Notes. The 11.00% / 13.00% Convertible Notes were issued pursuant to, and are governed by, an indenture, dated as of December 19, 2023, by and between the Company and GLAS Trust Company LLC, as trustee and collateral agent. The 11.00% / 13.00% Convertible Notes are the Company’s senior secured obligations and are secured by substantially all of the Company’s and its subsidiaries’ assets.

Interest on the 11.00% / 13.00% Convertible Notes is payable in cash, or at the Company’s election subject to certain limitations, with a combination of cash and shares of Common Stock (“blended payments”) or, with the agreement of the applicable holder, through payment-in-kind. The 11.00% / 13.00% Convertible Notes will accrue interest at a rate of 11.00% per annum in the case of cash payment and 13.00% in the case of blended payments or payments-in-kind, payable semi-annually in arrears on June 1 and December 1 of each year, with the initial payment on June 1, 2024. On December 19, 2023, the Company, Acquisition LP and Co-Invest LP agreed that payments of interest on 11.00% / 13.00% Convertible Notes held by Acquisition LP and Co-Invest LP would be made as payments-in-kind until Acquisition LP and Co-Invest LP provide five business days advance notice to the Company revoking this election.

The 11.00% / 13.00% Convertible Notes will mature on the earlier of December 19, 2028 and the date that is 90 days prior to the maturity of the 7.25% Convertible Notes solely to the extent there are 7.25% Convertible Notes outstanding in a principal amount equal to or greater than $5,000,000 as of such date, unless earlier repurchased, redeemed or converted.

At any time from the December 19, 2023 and before the close of business on the second scheduled trading day immediately before the maturity date, noteholders may convert their 11.00% / 13.00% Convertible Notes at their option into shares of Common Stock, together, if applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The initial conversion rate is 641.02564 shares of Common Stock per $1,000 principal amount of 11.00% / 13.00% Convertible Notes, which represents an initial conversion price of approximately $1.56 per share of Common Stock. Noteholders that convert their Notes will be entitled to an additional premium payment representing the amount of certain of the remaining interest payments on the 11.00% / 13.00% Convertible Notes as specified in the indenture, which the Company may settle in cash, shares of common stock, or a combination, subject to the terms of the indenture. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. The 11.00% / 13.00% Convertible Notes are subject to certain limitations on conversion, and limitations on the Company’s ability to issue Common Stock to satisfy obligations under the 11.00% / 13.00% Convertible Notes, including a limitation on the ability of the holder to convert or the Company to issue Common Stock if the holder’s beneficial ownership of Common Stock (together with its affiliates and certain attribution parties) would, in the case of Acquisition LP and Co-Invest LP, exceed 49.9% of the outstanding Common Stock.

The 11.00% / 13.00% Convertible Notes are redeemable, in whole and not in part, at the Company’s option at any time on or after December 19, 2024, and in some circumstances prior to that date, at a cash redemption price equal to the principal amount of the 11.00% / 13.00% Convertible Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Common Stock exceeds 150% of the conversion price on (i) each of at least 20 trading days, whether or not consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date the Company sends such notice.

If certain corporate events that constitute a “Fundamental Change” (as defined in the indenture) occur, then noteholders may require the Company to repurchase their 11.00% / 13.00% Convertible Notes at a cash repurchase price equal to the principal amount of the 11.00% / 13.00% Convertible Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. The definition of Fundamental Change includes certain business combination transactions involving the Company and certain de-listing events with respect to the Common Stock.

The indenture contains covenants restricting the Company’s ability to incur indebtedness, incur liens, make restricted payments, make asset sales and engage in transactions with affiliates, subject to certain baskets. The indenture also requires the Company to maintain minimum liquidity of $4 million and to add future assets to the collateral securing the 11.00% / 13.00% Convertible Notes and to add future subsidiaries as guarantors of the 11.00% / 13.00% Convertible Notes.

December 2023 Registration Rights Agreement

On December 19, 2023, in connection with the completion of the transactions contemplated by the December 2023 Purchase Agreement and the December 2023 Exchange Agreement, the Company, Acquisition LP, Acquisition 2 LP, Co-Invest LP and certain other parties thereto entered into a Registration Rights Agreement (the “December 2023 Registration Rights Agreement”), which requires the Company to register, among other things, the resale of all shares of Common Stock issuable upon conversion or exercise of, or otherwise issuable pursuant to, the 11.00% / 13.00% Convertible Notes, the December 2023 Additional Warrants or the December 2023 Exchange Warrants. The Company is required to prepare and file a registration statement with the SEC no later than five business days after the date of the agreement, and to use its commercially reasonable efforts to have the registration statement declared effective 120 days after the date of the agreement. The registration rights will expire on the earliest of (i) when a registration statement covering such securities becomes or has been declared effective by the SEC and such securities have been sold or disposed of pursuant to such effective registration statement; (ii) when such securities are held by the Company or one of its subsidiaries; and (iii) the date on which such securities may be sold by the holder thereof without volume or manner of sale restrictions under Rule 144 under the Securities Act.

March 2024 Offering Lock-Up and Voting Agreement

On March 31, 2024, the Company agreed to sell shares of Common Stock and warrants to purchase shares of Common Stock to certain institutional and accredited investors as part of the March 2024 Offering.

As a condition to the closing of the March 2024 Offering, each of the Funds is required to enter into a voting agreement with the Company (the “Voting Agreements”) pursuant to which each Fund agreed to vote all shares of Common Stock it holds for the approval of the issuance of shares of Common Stock pursuant to the terms of the warrants issued as part of the March 2024 Offering.
