A Partner in Simpson Thacher’s Litigation Department, Meredith Karp represents clients in a wide range of high-stakes complex commercial litigation, including securities, M&A and breach of contract disputes, as well as in connection with government and internal investigations, corporate governance matters and cross-border international arbitrations. Her work involves the representation of corporations, financial institutions, and private equity firms, as well as boards of directors, board committees and executives.


Meredith’s representative experience includes:

  • Valeant Pharmaceuticals in dozens of securities litigations;
  • The Toronto-Dominion Bank in litigation related to Robert Allen Stanford, orchestrator of one of the largest-ever Ponzi schemes; 
  • Paramount in a derivative and stockholder class action arising out of the merger between CBS and Viacom;
  • SeaWorld in a securities class action; shareholder derivative suit; and government investigations;
  • Commercial bank’s successor and acquiring entities in multiple federal and state enforcement and regulatory inquiries; 
  • TaskUs in a putative securities class action;
  • L3Harris in a securities class action; shareholder litigations; a breach of contract dispute; and government investigations;
  • Corp Group in an international arbitration regarding shareholder rights in a Colombian bank in excess of $600 million;
  • KKR in international arbitration and related cross-border litigation;
  • Virtus Investment Partners in obtaining denial of class certification; and
  • Blackstone and Kyndryl in breach of contract disputes.


In addition to the matters above, Meredith is also committed to pro bono work. Most recently, Meredith and the Simpson Thacher team, partnering with Campaign Legal Center and Kansas attorney Mark Johnson, secured a significant First Amendment victory on behalf of the Voter Participation Center following a bench trial on a paper record in the United States District Court for the District of Kansas. The Court’s ruling, which follows a 2021 entry of a preliminary injunction, permanently blocked the enforcement of anti-voter provisions in H.B. 2332, protecting voter access to personalized advance mail ballot applications in Kansas.


Meredith received her J.D. from Harvard Law School, where she received the Dean’s Scholar Prize, and her B.A., summa cum laude and with Distinction in all subjects, from Cornell University, where she was elected a member of Phi Beta Kappa.
