On December 14, 2021, Adagio disclosed that its COVID-19 treatment and prevention product, ADG20, was 300 times less effective at neutralizing the Omicron variant than it was against other variants, despite previous assurance of the efficacy against Omicron.

On this news, Adagio’s stock price fell $27, or 78.8%, to close at $7.26 per share on December 14, 2021, thereby injuring investors.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that the published epitope mapping, structural studies, and sequence analyses which defendants had used to claim ADG20 was effective against Omicron were insufficient, unreliable, and inadequate to make claims of effectiveness of ADG20 against Omicron; (2) that defendants’ claims regarding ADG20’s efficacy against Omicron lacked a reasonable factual basis; (3) that ADG20 was over 300 times less effective against the Omicron variant as compared to its effectiveness against previous variants; and (4) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
