Introductory Note

As previously announced, on April 24, 2023, Assertio Holdings, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Spade Merger Sub 1, Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), and Spectrum Pharmaceuticals, Inc., a Delaware corporation (“Spectrum”).

On July 27, 2023, the Company held a virtual special meeting of its stockholders (the “Special Meeting”) to vote on the proposals identified in the Company’s definitive joint proxy statement/prospectus initially filed with the Securities and Exchange Commission on June 2, 2023, and declared effective on June 15, 2023, and mailed to the Company’s stockholders on June 15, 2023. The stockholders approved all proposals.

On July 31, 2023, the Company completed the previously announced acquisition of Spectrum pursuant to the Merger Agreement. Under the Merger Agreement, Merger Sub merged with and into Spectrum (the “Merger”), with Spectrum surviving such Merger as a wholly owned subsidiary of the Company. The Merger became effective on July 31, 2023 upon the filing of the Certificate of Merger with the Secretary of the State of Delaware (the time of such filing, the “Effective Time”). Additionally, on July 31, 2023, in connection with the Merger Agreement, Assertio and Computershare Trust Company, N.A., as rights agent, entered into a contingent value right (“CVR”) agreement, pursuant to which each holder of (i) common stock, par value $0.001 per share, of Spectrum (“Spectrum Common Stock”) (other than holders of Common Stock (x) that was canceled in accordance with the terms of the Merger Agreement or (y) who properly exercised appraisal rights under Delaware law) and (ii) Spectrum restricted stock units ("Spectrum RSUs"), certain stock appreciation rights (“Spectrum SARs”), certain options to purchase Spectrum Common Stock (“Spectrum Stock Options”) and warrants to purchase Spectrum Common Stock (“Spectrum Warrants”), were entitled to one CVR. Each CVR entitled the holder thereof to receive contingent payments of cash or common stock, par value $0.0001 per share, of the Company (“Company Common Stock”) upon the achievement of certain milestones.

The following events took place in connection with the completion of the Merger.

Item 2.01 Completion of Acquisition or Disposition of Assets

The information included in the Introductory Note is incorporated herein by reference into this Item 2.01.

Merger Consideration

Under the Merger Agreement, at the Effective Time, each share of Spectrum Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) treasury shares, (ii) any shares of Spectrum Common Stock held directly by the Company or Merger Sub and (iii) shares of Spectrum Common Stock held by any holder who properly demanded appraisal of such shares in compliance with Section 262 of the Delaware General Corporation Law) was converted into the right to receive (A) 0.1783 (the “Exchange Ratio”) of a fully paid and non-assessable share of Company Common Stock and, if applicable, cash in lieu of fractional shares, subject to any applicable withholding (the “Upfront Consideration”), and (B) one CVR representing a contractual right to receive future conditional payments worth up to an aggregate maximum amount of $0.20, settleable in cash, additional shares of common stock of the Company or a combination of cash and additional shares of common stock of the Company, at the Company’s sole discretion (and subject, in each case, to deduction for any required withholding taxes), upon the achievement of certain sales milestones related to Spectrum’s product ROLVEDON^® (collectively, with the Upfront Consideration, the “Merger Consideration”).

At the Effective Time, each Spectrum Stock Option (other than an option under Spectrum’s employee stock purchase plan) to purchase Spectrum Common Stock granted under any of Spectrum’s equity incentive plans, that was outstanding immediately prior to the Effective Time became vested (if unvested) and was automatically and without any required action on the part of the holder or Spectrum, cancelled and treated as follows:

At the Effective Time, each Spectrum RSU with respect to Spectrum Common Stock granted under Spectrum’s equity incentive plans, whether vested or unvested, that was outstanding immediately prior to the Effective Time became fully vested, and the holder of such Spectrum RSUs automatically and without any required action on the part of the holder thereof or Spectrum received the Merger Consideration.

At the Effective Time, each unvested restricted Spectrum Common Stock granted under Spectrum’s equity incentive plans that was outstanding immediately prior to the Effective Time automatically and without any required action on the part of the holder thereof or Spectrum, became fully vested and is now treated like all other shares of Spectrum Common Stock.

At the Effective Time, each Spectrum SAR granted under Spectrum equity incentive plans that was outstanding as of immediately prior to the Effective Time, became vested (if unvested) and was automatically, and without any required action on the part of the holder or Spectrum, cancelled and treated as follows:

At the Effective Time, upon the election of the holder of each Spectrum Warrant, under that certain Warrant to Purchase Stock, dated as of September 21, 2022, by and between Spectrum and SLR Investment Corp., a Maryland corporation, that was outstanding immediately prior to the Effective Time were cancelled and, in exchange therefor, Spectrum shall pay to each former holder of any such cancelled Spectrum Warrant as soon as practicable following the Effective Time (i) a number of shares of Company Common Stock equal to the (A) product of (x) the excess of $1.10 over the exercise price per Spectrum Common Stock under such Spectrum Warrant, and (y) the number of shares of Spectrum Common Stock subject to such Spectrum Warrant, multiplied by (B) the Exchange Ratio, and (ii) one CVR for Spectrum Common Stock underlying such Spectrum Warrant, in each case, without interest, and subject to deduction for any required withholding of taxes.

The foregoing description of the Merger Agreement and the Merger does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which was attached as Exhibit 2.1 of the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (the “SEC”) on April 25, 2023, the terms of which are incorporated herein by reference.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

Appointment of Jeffrey Vacirca, MD, FACP, to the Company’s Board of Directors

As of the Effective Time and in accordance with the Merger Agreement, the Company’s Board of Directors (the “Board”) voted to increase the size of the Board from five directors to six directors and appointed Jeffrey Vacirca, MD, FACP to the Board. The Board has determined that Mr. Vacirca qualifies as an independent director under the corporate governance standards of The Nasdaq Stock Market and the applicable rules adopted by the U.S. Securities and Exchange Commission (the “SEC”).

The compensation of Mr. Vacirca for his service as a non-employee director will be consistent with that of the Company’s other non-employee directors, which is described in the Company’s definitive proxy statement filed on April 3, 2023 with the SEC.

Item 5.07 Submission of Matters to a Vote of Security Holders.

The information included in the Introductory Note is incorporated herein by reference into this Item 5.07.

As of June 13, 2023, the record date for the Special Meeting, there were 56,512,962 shares of the Company’s common stock issued and outstanding. At the Special Meeting, a total of 32,883,168 shares of the Company’s common stock were present virtually or by proxy, representing 58.187% of the total number of shares outstanding and entitled to vote at the Special Meeting and a quorum for all matters before the stockholders as required by the Company’s Amended and Restated Bylaws, as amended.

The number of votes cast for and against, as well as abstention votes and broker non-votes, as applicable, with respect to each proposal presented at the Special Meeting was as follows:

Proposal No. 1 - Approval of the Share Issuance.

The stockholders approved the issuance of shares of the Company’s common stock to Spectrum stockholders in connection with the Merger (including such shares issued as payment under the non-tradeable contingent value rights) (the “Assertio share issuance proposal”) as follows:

Proposal No. 2 - Adjournment of the Assertio Special Meeting.

The stockholders approved the proposal to adjourn the Special Meeting to solicit additional proxies if there are insufficient votes to approve the Assertio share issuance proposal or to ensure that any supplement or amendment to the joint proxy statement/prospectus is timely provided to Assertio stockholders as follows:

However, because Proposal No. 1 to approve the Assertio share issuance proposal was approved, the adjournment of the Special Meeting was not necessary to continue to solicit additional proxies and, accordingly, the Special Meeting was not adjourned.
