HSW Wins Full Dismissal of Securities Class Action in SDNY

March 4, 2026

Harris St. Laurent & Wechsler LLP secured dismissal of all claims against former Integral Ad Science Holding Corp. Chief Financial Officer Tania Secor in a securities class action pending in the U.S. District Court for the Southern District of New York.

In Oklahoma Firefighters Pension & Retirement System v. Integral Ad Science Holding Corp., et al., the plaintiffs asserted claims under Section 10(b) of the Securities Exchange Act and Rule 10b-5, alleging that IAS and certain executives misled investors regarding pricing competition and revenue performance. The complaint also challenged the company's stock sales by Vista Equity Partners, its former majority shareholder.

HSW moved to dismiss the complaint for failure to state a claim under the heightened pleading standards of the Private Securities Litigation Reform Act. Judge Lewis A. Kaplan granted the motion, dismissing all claims against all defendants and denying the plaintiffs leave to amend.

The decision fully resolves the claims asserted in the SDNY action.

Partner Andrew St. Laurent led the representation of Secor, with significant contributions from associate Megan Gao.

IAS and Vista Equity Partners are represented by Kirkland & Ellis, and Berman Tabacco represented the plaintiff.
