The lawsuit alleges that Defendants made materially false and/or misleading statements and/or failed to disclose material adverse information, including allegations that: (i) DexCom had made material design changes to the G6 and G7 unauthorized by the United States Food and Drug Administration (the "FDA"); (ii) the foregoing design changes rendered the G6 and G7 less reliable than their prior iterations, presenting a material health risk to users relying on those devices for accurate glucose readings; (iii) accordingly, Defendants' purported enhancements to the G7, as well as the device's reliability, accuracy, and functionality, were overstated; (iv) Defendants downplayed the true scope and severity of the issues and health risks posed by adulterated G7 devices; (v) all the foregoing subjected DexCom to an increased risk of heightened regulatory scrutiny and enforcement action, as well as significant legal, reputational, and financial harm; and (vi) as a result, Defendants' public statements were materially false and/or misleading at all relevant times.
