Item 3. Source and Amount of Funds or Other Consideration.

On October 27, 2017, the Company and Co-Invest LP entered into a Series B Preferred Stock Purchase Agreement (the “2017 Series B Stock Purchase Agreement”), which provided for the sale of shares of Series B Preferred Stock at a purchase price of $3.53 per share for an aggregate purchase price of $50.0 million.

On August 27, 2019, the Company and Acquisition LP entered into a Series B Preferred Stock Purchase Agreement pursuant to which Acquisition LP purchased shares of Series B Preferred Stock at $2.75 per share for an aggregate purchase price of $25.0 million.

On November 12, 2019, the Company and Acquisition LP entered into a Series B Stock Preferred Stock Purchase Agreement (the “2019 Series B Stock Purchase Agreement”) pursuant to which Acquisition LP purchased additional shares of Series B Preferred Stock at $2.25 per share for an aggregate purchase price of $25.0 million. The conversion price of the Series B Preferred Stock was lowered from $2.75 to $2.25 per share (or $13.90 per share as a result of the reverse stock split effected on June 10, 2020). Also on November 12, 2019, Acquisition 2 LP acquired all of the securities of the Company held by Acquisition LP.

On December 19, 2019 and February 28, 2020, Acquisition 2 LP purchased additional shares of Series B Preferred Stock pursuant to the 2019 Series B Stock Purchase Agreement for an aggregate purchase price of $25.0 million and $10.0 million, respectively, at a purchase price of $2.25 per share.

On March 31, 2020, Co-Invest LP and the Company entered into the First Amendment to the Credit Agreement (the “Credit Agreement Amendment”) providing for the payment in shares of the Company’s Series B Preferred Stock of the interest on the amount outstanding under the applicable credit agreement.

On April 3, 2020, the Company and Acquisition 2 LP entered into a Series B Preferred Stock Purchase Agreement pursuant to which Acquisition 2 LP purchased additional shares of Series B Preferred Stock at $2.25 per share for an aggregate purchase price of $10.0 million.

On May 8, 2020, the Company and 2020 LP entered into a Note Purchase Agreement pursuant to which 2020 LP purchased an unsecured convertible promissory note (the “Convertible Promissory Note”) with an annual interest rate of 8.0% and in an aggregate principal amount of $15.0 million.

In connection with the consummation of the Company’s initial public offering of its Common Stock, the Series B Preferred Stock and the Convertible Promissory Note converted, automatically and without any additional consideration, into 18,319,853 and 1,250,000 shares, respectively, of Common Stock. Further, on June 23, 2020, in connection with the initial public offering of the Company’s Common Stock, 2020 LP purchased 3,333,333 shares of Common Stock at a price of $15.00 per share. The funds used to purchase such shares were composed of the investment capital of 2020 LP.

On December 7, 2020, the Company consummated a follow-on public offering of its Common Stock and a concurrent private placement of its 7.25% convertible senior notes due 2025 (the “7.25% Convertible Notes”). Acquisition 2 purchased 4,128,440 shares of Common Stock, and Acquisition LP purchased an aggregate principal amount of $25,000,000 of the 7.25% Convertible Notes in connection with the offerings. Such shares of Common Stock were purchased for $3.27 per share of Common Stock for an aggregate purchase price of $13.5 million, and such 7.25% Convertible Notes were purchased for $25.0 million in cash, in each case at the same price offered to the public. The funds used to purchase such shares and 7.25% Convertible Notes, as applicable, were composed of the investment capital of the applicable Fund. At the same time, Co-Invest LP consummated an agreement to receive an aggregate principal amount of $78,500,000 of the 7.25% Convertible Notes and $95,833.33 in cash in exchange for the cancellation of the $78.6 million in principal and accrued and unpaid interest outstanding, as well as a prepayment penalty, under the Company’s credit agreement for which Co-Invest LP acted as the lender and collateral agent.

On June 1, 2021, Acquisition LP and Co-Invest LP entered into a Consent and Waiver Agreement and, on May 27, 2021, a Stock Issuance Agreement (the “Stock Issuance Agreement”), each with the Company, pursuant to which Acquisition LP and Co-Invest LP agreed to forgo and waive their right to receive interest in cash due on the 7.25% Convertible Notes held by Acquisition LP and Co-Invest LP, in exchange for the issuance of shares of Common Stock equal to $3,626,812.50, the amount of cash interest so waived, for a price of $2.86 per share. Pursuant to the Stock Issuance Agreement, Acquisition LP acquired 306,308 shares of Common Stock and Co-Invest LP acquired 961,807 shares of Common Stock.

On June 14, 2021, the Company consummated a private placement of units (the “Private Placement”), with each unit consisting of one share of Common Stock and the right to buy an additional share of Common Stock for the exercise price specified in the warrant conferring such right (the “Common Stock Warrant”). In connection with the Private Placement, Acquisition 2 LP purchased 8,097,166 units for a price of $2.47 per unit and with an aggregate purchase price of $20.0 million.

On November 6, 2022, the Company and Acquisition 2 LP agreed to amend the Common Stock Warrant (as amended, the “Amended Warrant”) to reduce the exercise price to $0.3288 per share of Common Stock. The Amended Warrant is exercisable at any time on or after May 9, 2023 and until May 9, 2028, but not thereafter.

On November 6, 2022, Acquisition LP and Co-Invest LP entered into an Interest Waiver and Securities Issuance Agreement and a Securities Purchase Agreement (collectively, the “Interest Waiver Agreements”), in each case with the Company, pursuant to which Acquisition LP and Co-Invest LP agreed to forego and waive their right to receive an aggregate amount of $3,751,875 in cash interest due on the 7.25% Convertible Notes held by Acquisition LP and Co-Invest LP, in exchange for the issuance of shares of Common Stock and warrants to purchase an additional share of Common Stock (the “Second Common Stock Warrant”). In connection with the Interest Waiver Agreements, Acquisition LP acquired 3,020,833 shares of Common Stock and the right to purchase 3,020,833 shares of Common Stock pursuant to the Second Common Stock Warrant and Co-Invest LP acquired 9,485,417 shares of Common Stock and the right to purchase 9,485,417 shares of Common Stock pursuant to the Second Common Stock Warrant. The Second Common Stock Warrant has an exercise price of $0.3288 per share and is exercisable at any time on or after May 9, 2023 and until May 9, 2028, but not thereafter.

Item 4. Purpose of Transaction.

The Reporting Persons acquired the securities reported herein for investment purposes and intend to review their investments in the Company on a continuing basis. 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, previously announced restructuring, 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 capitalization 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 71,136,069 shares of Common Stock, which represents approximately 28.4% of the outstanding shares of Common Stock. All calculations of percentage ownership in this Schedule 13D are based on (i) 221,603,559 shares of Common Stock outstanding as disclosed in the Company’s prospectus filed with the SEC on November 9, 2022, and (ii) plus shares issuable upon conversion of the 7.25% Convertible Notes held by the Reporting Persons. The shares beneficially owned by the Reporting Persons do not include any of the shares underlying the Amended Warrant or the Second Common Stock Warrant since such warrants are not exercisable until May 9, 2023 and therefore do not represent a right to acquire the underlying shares of Common Stock within 60 days of this Schedule 13D.

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) five years after the completion of the Company’s initial public offering, (ii) 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.

On May 31, 2021, the Company and the other stockholders party thereto entered into Amendment No. 3 to the Investors’ Rights Agreement in order to provide for the registration of the shares of Common Stock issued pursuant to the Stock Issuance Agreement.

On August 19, 2021, in connection with the proposed sale by the Company of Common Stock and warrants to purchase Common Stock pursuant to the Company’s registration statement on Form S-3 filed with the SEC on July 30, 2021 (the “Shelf Registration Statement”), the Company and the stockholders party to the Investors’ Rights Agreement entered into that certain Notice and Waiver, pursuant to which such stockholders waived their respective right to request that the Company include the securities registrable pursuant to the Investor Rights Agreement among the securities registered on the Shelf Registration Statement.

7.25% Convertible Notes

On December 7, 2020, the Company issued a new series of 7.25% Convertible Notes. The 7.25% Convertible Notes were issued pursuant to, and are governed by, an indenture (the “Indenture”), dated as of December 7, 2020, by and between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. The initial conversion rate is 278.0094 shares of Common Stock per $1,000 principal amount of 7.25% Convertible Notes, which represents an initial conversion price of approximately $3.60 per share of Common Stock. The conversion rate and conversion price will be subject to customary adjustments upon the occurrence of certain events. In addition, if certain corporate events that constitute a “Make-Whole Fundamental Change” (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time.

Common Stock Warrant and Amended Warrant

On June 14, 2021, the Company issued a Common Stock Warrant to Acquisition 2 LP as registered holder. On November 6, 2022, the Company and Acquisition 2 LP agreed to amend the Common Stock Warrant. This Amended Warrant is exercisable for 8,097,166 shares of Common Stock at an exercise price of $0.3288 per share, at any time on or after May 9, 2023 and prior to May 9, 2028.

Second Common Stock Warrant

On November 9, 2022, the Company issued the Second Common Stock Warrant to Acquisition LP and Co-Invest LP in connection with the Interest Waiver Agreements. The Second Common Stock Warrant is exercisable for 12,506,250 shares of Common Stock, has an exercise price of $0.3288 per share of Common Stock and is exercisable at any time between May 9, 2023 and prior to its expiration on May 9, 2028.
