Item 8.01 Other Events.

As previously disclosed by Celldex Therapeutics, Inc. (the “Registrant”) in its Annual Report on Form 10-K for the year ended December 31, 2019, and in subsequent Quarterly Reports on Form 10-Q, the Registrant sent an abandonment notice to Shareholder Representative Services LLC (“SRS”) (in its capacity as the representative of the former stockholders of Kolltan Pharmaceuticals, Inc. (“Kolltan”)) with respect to the abandonment of certain development, regulatory approval and sales-based milestones contained in the Agreement and Plan of Merger, dated November 1, 2016, by and among Kolltan, Connemara Merger Sub 1, Inc., Connemara Merger Sub 2 LLC, and SRS (the “Merger Agreement”). Also, as previously disclosed by the Registrant, SRS objected to that abandonment notice, and the Registrant disagreed with their objection, believed their objection to be without merit, and the Company entered into discussions with respect to potential amendments to the Merger Agreement with respect to the milestones with SRS. The Registrant and SRS have been unable to reach agreement with respect to that amendment.

On August 18, 2020, the Registrant filed a Verified Complaint in the Court of Chancery of the State of Delaware against SRS (acting in its capacity as the representative of the former stockholders of Kolltan pursuant to the Merger Agreement) seeking declaratory relief.

The action seeks an order from the Court of Chancery declaring the rights and obligations of the parties with respect to certain contingent milestone payments under the Merger Agreement. Specifically, the Registrant seeks the entry of an order declaring that:

(i) the Registrant’s determination to discontinue the development of CDX-0158 (formerly known as KTN0158) was proper and valid under the Merger Agreement;

(ii) the Milestone Abandonment Notice dated December 5, 2018 from the Registrant was valid and effective under the Merger Agreement and that the “Successful Completion of Phase I Clinical Trial for KTN0158” Milestone has not been achieved and has properly been abandoned; and

(iii) under the Merger Agreement as written, the CDX-0159 program is not a program that results in milestone payments under the Merger Agreement (supported by the determination of the Food and Drug Administration in September 2018 that the Registrant’s CDX-0159 is a New Molecular Entity that is distinct from CDX-0158 (formerly known as KTN0158) and thus the FDA required preclinical studies of CDX-0159 to be completed before clinical development of CDX-0159 could commence). As such, CDX-0159 should according to the terms of the Merger Agreement not be considered in determining whether any of the milestones therein identified have been achieved.
