The complaint alleges that throughout the Class Period, Defendants made materially false and misleading statements and failed to disclose that:

Key Events:

• March 10, 2025 – FDA Warning Letter:
  The FDA issued a Warning Letter stating that DexCom had "adulterated" its G6 and G7 sensors by modifying them without prior approval, resulting in larger inaccuracies and increased health risks for users.  Stock dropped $7.12 (−9.15%) to $70.72.

• March 25–26, 2025 – Public Disclosure:
  The FDA published the Warning Letter on its website, further confirming the product issues. Stock fell another $3.19 (−4.24%) to $72.13.

• September 8, 2025 – Oppenheimer Downgrade:
  Oppenheimer downgraded DexCom to "perform" from "outperform", citing rising patient concerns over G7 sensor accuracy issues, failed insertions, and abrupt stoppages. Stock declined $2.51 (−3.12%) to $78.00.

• September 18, 2025 – Hunterbrook Report:
  Hunterbrook Research published a report titled "DexCom's Fatal Flaws," revealing through FDA records and interviews that G7 devices had caused hospitalizations and deaths due to inaccurate readings. The report accused DexCom of cutting corners to protect margins. Stock plunged $8.99 (−11.76%) over two sessions to $67.45.
