On September 29, 2025, the Issuer commenced an offer to exchange its Existing Convertible Notes for the new Notes and new shares of its Common Stock in order to reduce its leverage and extend its debt maturity (the "Exchange Offer"). Prior to October 10, 2025, the Reporting Persons tendered $117,820,000 in aggregate principal of the Existing Convertible Notes, which were held as an investment by WFFTL, in the Exchange Offer, and received 33,418,911 new shares of the Issuer's Common Stock and $23,486,000 in aggregate principal of the new Notes. On October 15, 2025, the Issuer completed the early settlement of the exchange of the Existing Convertible Notes that were validly tendered on or before the early tender deadline of 5:00 pm New York City time, on October 10, 2025 in the Exchange Offer. The new Notes were issued pursuant to an indenture, dated as of October 15, 2025 (the "New Convertible Notes Indenture"), by and between the Issuer and Wilmington Trust, National Association, as trustee and collateral agent (in such capacity, the "Collateral Agent"). The new Notes will mature on October 15, 2030 unless earlier redeemed, converted, equitized or repurchased in accordance with the terms of the new Notes. The new Notes bear interest at a rate of 7.00% per annum from October 15, 2025, which interest may be paid in cash or, subject to certain limitations, in shares of Common Stock. At the option of the Issuer, interest on the new Notes may be accrued and compounded in whole or in part for any interest period as "payment-in-kind" interest at a rate of 9.50% per annum from October 15, 2025. Pursuant to the New Convertible Notes Indenture, prior to obtaining stockholder approval of certain proposals that will allow the issuance of Common Stock pursuant to the terms of the new Notes (the "Requisite Stockholder Approval"), the Issuer will be permitted to satisfy its obligations upon conversion of the new Notes only in the form of cash settlement. Following the Requisite Stockholder Approval, the Issuer will be permitted to satisfy its obligations under the new Notes with any settlement method it is otherwise permitted to elect, including by cash, physical settlement of shares of Common Stock, or a combination of cash and shares of Common Stock (the "Issuer's Settlement Method Election"). A holder of new Notes will not be permitted to convert its new Notes at any time prior to the earlier of, (a) the date of the first special meeting at which the Issuer seeks stockholder approval of such proposals, whether or not such approvals are obtained and (b) the date that is 61 calendar days following the initial settlement date of the new Notes ("Convertibility Date"). Thereafter, the Notes will be convertible at any time prior to the close of business on the second trading day immediately preceding the maturity date. Pursuant to the New Convertible Notes Indenture, no new Note will be optionally convertible by the holder, and the Issuer will not effect any conversion of a new Note, to the extent that, after giving effect to such conversion, the holder together with any of the holder's Attribution Parties (as defined in the New Convertible Notes Indenture) collectively would beneficially own in excess of 9.9% of the shares of Common Stock outstanding immediately after giving effect to such conversion (the "9.9% Blocker"). The conversion rate for the new Notes will initially be a number of shares of Common Stock per $1,000 principal amount of new Notes equal to the lesser of (i) 1,029.2716 and (ii) an amount calculated based on a 10% premium to a reference price determined over an observation period consisting of 20 consecutive trading days immediately following October 15, 2025, with such conversion rate subject to customary adjustments. The conversion rate will be increased for conversions occurring prior to October 15, 2028 to reflect a "make-whole" premium, payable in the form of shares of Common Stock, to compensate holders for interest that would have been payable to such date. If certain corporate events constituting a make-whole fundamental change occur (which shall include, among other things, the acquisition by any person or group of more than 50% of the outstanding Common Stock or a delisting of the Common Stock), the Issuer shall offer to repurchase all of the outstanding new Notes for cash at a repurchase price equal to 100% of the aggregate principal amount of the new Notes then outstanding plus accrued and unpaid interest. If a fundamental change occurs, then the Issuer will in certain circumstances increase the conversion rate for the new Notes for a specified period of time on the terms set forth in the New Convertible Notes Indenture. The foregoing description of the New Convertible Notes Indenture does not purport to be complete and is qualified in its entirety by reference to the full text of the New Convertible Notes Indenture, a copy of which is attached hereto as Exhibit 3 and is incorporated by reference herein. In connection with the Exchange Offer, the Issuer entered into a transaction support agreement dated September 29, 2025 (the "Transaction Support Agreement") with certain beneficial owners or nominees, investment managers or advisors for beneficial holders of the Existing Convertible Notes, including WAM, who collectively held approximately 47% of the aggregate principal amount of the Existing Convertible Notes (the "Supporting Noteholders") as of the effective date of the Transaction Support Agreement. Pursuant to the Transaction Support Agreement, the Supporting Noteholders agreed, among other things, to tender all of their Existing Convertible Notes in the Exchange Offer prior to October 10, 2025 (the "Early Tender Date") and to consent to the Proposed Amendments on or before the Early Tender Date. The Issuer also agreed in the Transaction Support Agreement to pay or cause to be paid to the Supporting Noteholders, in proportion to the principal amount of Existing Convertible Notes held by each such Supporting Noteholder, a non-refundable amount at the initial settlement date of the new Notes equal to $12.5 million in aggregate principal amount of new Notes (the "SteerCo Premium"). The Reporting Persons received an additional aggregate principal amount of $2,741,000 in the new Notes as a result of the SteerCo Premium. Pursuant to the terms of the Transaction Support Agreement, WAM and each of the other Supporting Noteholders represented and warranted that it has not formed a "group" (within the meaning of Section 13(d)(3) of the Act) with any other Supporting Noteholder(s) (other than, for the avoidance of doubt, any Supporting Noteholders that are affiliates of such Supporting Noteholder) and has no current intention of doing so, and the parties to the Transaction Support Agreement agreed that no Supporting Noteholder shall, as a result of its entering into and performing its obligations under the Transaction Support Agreement, be deemed to be a part of a "group" (as that term is used in Rule 13d-5 under the Act) with any other party to the Transaction Support Agreement. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission by the Reporting Persons that they are a part of a group with the Supporting Noteholders or the beneficial owner of any of the shares of Common Stock beneficially owned by any Supporting Noteholders for purposes of Section 13(d) of the Act or for any other purpose, and such beneficial ownership is expressly disclaimed. The foregoing description of the Transaction Support Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Transaction Support Agreement, a copy of which is attached hereto as Exhibit 4 and is incorporated by reference herein. Also on September 29, 2025, WAM and each of the other Supporting Noteholders individually entered into a voting agreement with the Issuer (the "Voting Agreements") whereby such Supporting Noteholder agreed with the Issuer that it will appear at each special or annual meeting at which a vote is held on the Proposals (as defined in the Voting Agreement) until the earlier of (i) the termination, withdrawal and abandonment by the Issuer of the Exchange Offer prior to the initial settlement date of the new Notes and shares of Common Stock in the Exchange Offer, (ii) the date following the date of the Issuer's annual meeting in 2026, (iii) the date the Proposals are approved and (iv) June 19, 2026, or otherwise cause the shares of Common Stock it beneficially owns to be counted as present thereat for purposes of determining a quorum, and be present (in person or by proxy, which includes by remote communication) and vote (or cause to be voted) all of its shares of Common Stock it beneficially owns in favor of the Proposals. In addition, pursuant to the terms of the Voting Agreements, WAM and each of the other Supporting Noteholders has agreed with the Issuer that it shall not, from and after the initial settlement date of the new Notes and shares of Common Stock in the Exchange Offer and until 5:00 p.m., New York City time on the date that is the earlier of (i) the record date of the first special meeting proposed to be held following the consummation of the Exchange Offer and (ii) the date that is three (3) business days following the initial settlement date of the new Notes and shares of Common Stock in the Exchange Offer, transfer, sell, exchange, assign or convey any legal or beneficial ownership interest in, or any right, title or interest therein (including any right or power to vote), or otherwise dispose of (whether by sale, liquidation, dissolution, dividend, distribution or otherwise) any shares of Common Stock issued in the Exchange Offer, or enter into any contract, option, or other agreement with respect to any of the foregoing; provided, the lock-up will provide that an exchanging holder of the Existing Convertible Notes may sell its pro rata portion of the amount of shares of Common Stock it receives in the Exchange Offer that represents the amount by which the shares of Common Stock issued at the initial settlement date of the Exchange Offer that are subject to Voting Agreements at such time (whether entered into with the Issuer directly or pursuant to the terms of the Exchange Offer) exceed 50.1% of the shares of Common Stock outstanding on the initial settlement date of the new Notes and shares of Common Stock in the Exchange Offer. The foregoing description of the Voting Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Voting Agreement, a copy of which is attached hereto as Exhibit 5 and is incorporated by reference herein. The Reporting Persons acquired the securities reported herein for the account of WFFTL for investment purposes and in the ordinary course of their business. The Reporting Persons expect to review from time to time their investment in the Issuer and may, depending on the market, contractual obligations (including those disclosed herein), and other conditions: (i) purchase additional shares of Common Stock, new Notes, options or other securities in the open market, in privately negotiated transactions, directly from the Issuer, or otherwise; and (ii) sell all or a portion of the shares of Common Stock, new Notes, options or other securities now beneficially owned or hereafter acquired by them.
