Sidney Hsu v. PubMatic, Inc., et al.

Hsu · United States District Court for the Northern District of California · November 25, 2025 · No. 25-cv-07067-JSC

Summary

The United States District Court for the Northern District of California appoints Sidney Hsu as lead plaintiff in a Private Securities Litigation Reform Act class action involving PubMatic, Inc. securities. The Court appoints Glancy Prongay & Murray LLP as lead counsel and denies Julie Kim’s competing motion, concluding that her assigned claims may not give her a financial stake and subject her to unique standing defenses. The order also sets duties for lead counsel and requires the parties to meet and confer regarding a consolidated amended complaint.

Holdings

  1. Kim's assigned claims did not provide her with a financial stake in the action because the assignment directed the litigation proceeds to the assignor, Lee.
  2. Kim was subject to a unique standing defense that rendered her incapable of adequately representing the class, rebutting any presumption in her favor.
  3. Hsu was the proper lead plaintiff because he had the next greatest financial interest after Kim was disqualified and made a prima facie showing of typicality and adequacy.

Questions Presented

  1. Which movant was entitled to the PSLRA presumption of being the most adequate lead plaintiff?
  2. Whether Kim's assignment agreement gave her a financial interest in the litigation and subjected her to a unique standing defense that rebutted the lead-plaintiff presumption.
  3. Whether Hsu made a prima facie showing of typicality and adequacy under Federal Rule of Civil Procedure 23.
  4. Whether Glancy Prongay & Murray LLP should be appointed lead counsel.
