Shareholder Litigation

As previously disclosed in Menlo’s Registration Statement on Form S-4, on December 11, 2019 and December 18, 2019, purported shareholders of Foamix filed putative class action lawsuits against the members of Foamix’s board of directors (the “Foamix Board”), Foamix, Menlo and Merger Sub in the United States District Court for the District of Delaware and in the United States District Court for the District of New Jersey, respectively, and on December 12, 2019, December 17, 2019 and December 20, 2019, purported shareholders of Foamix filed individual lawsuits against the members of the Foamix Board and Foamix in the United States District Court for the District of New Jersey, the United States District Court for the Southern District of New York and the United States District Court for the Southern District of New York, respectively.

On January 7, 2020, a purported shareholder of Foamix filed a lawsuit against Foamix and the members of the Foamix Board in the United States District Court for the District of New Jersey, alleging that the joint proxy statement/prospectus issued in connection with the merger omitted material information in violation of Section 14(a) and Section 20(a) of the Securities Exchange Act of 1934 and Rule 14a-9 promulgated thereunder (the “Exchange Act”). The action, captioned Bushansky v. Foamix Pharmaceuticals Ltd., et al., Case No. 3:20-cv-00256 (D.N.J.), purports to be brought on behalf of the named plaintiff only and seeks, among other things, injunctive or other equitable relief, including to enjoin consummation of the merger, or alternatively rescission or rescissory damages, a declaration that the defendants violated Sections 14(a) and/or 20(a) of the Exchange Act, and an award of costs, including attorneys’ and experts’ fees and expenses. The defendants believe the lawsuit is without merit and intend to defend vigorously against it.
