There is no cost or obligation to you.

The complaint alleges that, throughout the Class Period, Defendants made materially false and misleading statements regarding the Company’s business, operations, and prospects. Specifically, Defendants made false and/or misleading statements and/or failed to disclose that: (i) the data submitted in support of the Tebipenem HBr NDA were insufficient to obtain FDA approval; (ii) accordingly, it was unlikely that the FDA would approve the Tebipenem HBr NDA in its current form; (iii) the foregoing would necessitate a significant workforce reduction and restructuring of Spero’s operations; and (iv) as a result, the Company’s public statements were materially false and misleading at all relevant times.

A lead plaintiff will act on behalf of all other class members in directing the Spero class-action lawsuit. The lead plaintiff can select a law firm of its choice to litigate the class-action lawsuit. An investor’s ability to share any potential future recovery of the Spero class action lawsuit is not dependent upon serving as lead plaintiff.
