Alonzo v. Dexcom Inc.
3:24-cv-01485
S.D. Cal.Dec 13, 2024Background
- Three federal securities class actions were filed against Dexcom, Inc. and its executives by shareholders, all alleging materially false and misleading statements related to Dexcom’s G7 glucose monitoring system, resulting in a significant stock drop after disappointing 2024 financial results.
- Plaintiffs sought consolidation of actions, appointment of lead plaintiff, and lead counsel. Four parties moved for these roles: K. George Thampy, Oakland County Employee entities, Dexcom Investor Group, and National Elevator Industry Pension Fund (Pension Fund).
- Thampy and Oakland County dropped out, leaving Dexcom Group (a coalition of unrelated investors formed post-litigation start) and Pension Fund (institutional investor) opposing each other.
- The court was required under the PSLRA to first determine whether to consolidate the cases before appointing a lead plaintiff and lead counsel.
- All actions alleged essentially the same Exchange Act §10(b) and §20(a) claims, over nearly identical class periods, focused on the share price impact of alleged misleading statements about Dexcom’s business.
