“Certain Litigation
In connection with the Merger
Agreement, seven complaints have been filed by purported Company stockholders as individual actions in United States District Courts against the Company and the Company’s directors. Six complaints have been filed in the United States District
Court for the Southern District of New York and are captioned O’Dell v. Forma Therapeutics Holdings, Inc., et al., 22-cv-7931 (filed September 16,
2022), Morgan v. Forma Therapeutics Holdings, Inc., et al., 22-cv-8243 (filed September 27, 2022), Whitfield v. Forma Therapeutics Holdings, Inc., et
al., 22-cv-8263 (filed September 27, 2022), Justice v. Forma Therapeutics Holdings, Inc., et al., 22-cv-8268 (filed September 28, 2022) Bushansky v. Forma Therapeutics Holdings, Inc., et al., 22-cv-8314 (filed
September 29, 2022), and Scott v. Forma Therapeutics Holdings, Inc., et al., 22-cv-8399 (filed October 1, 2022). One complaint has been filed in the
United States District Court for the District of Delaware and is captioned Johnson v. Forma Therapeutics Holdings, Inc., et al., 22-cv-1275 (filed
September 28, 2022). The foregoing complaints are referred to as the “Complaints.”
The Complaints allege that the defendants violated
federal securities laws by misrepresenting and/or omitting material information in the Schedule 14D-9. The Complaints seek, among other things, (i) injunctive relief preventing the consummation
of the Transactions contemplated by the Merger Agreement, (ii) rescissory damages or rescission in the event that the transactions contemplated by the Merger Agreement have already been consummated, (iii) damages, and
(iv) plaintiff’s attorneys’ and experts’ fees and expenses. The Company has also received a demand letter from a purported Company shareholder (the “Demand”) requesting that the Company provide additional
disclosures in connection with the Transactions. The Company believes that the claims asserted in the Complaints and the Demand are without merit and intends to defend vigorously against such claims. Additional lawsuits may be filed against the
Company, the Company Board, the Purchaser and/or the Surviving Corporation, and additional demand letters may be received, in connection with the Transactions, the Schedule TO and the
Schedule 14D-9.”
