The complaint alleges that on December 7, 2021, AeroVironment announced second quarter results below market estimates and reduced revenue guidance for the remainder of the fiscal year from a range of $560 million to $580 million to a range of $440 million to $460 million. AeroVironment also lowered its EBITDA guidance from $105 million to $110 million to $59 million to $65 million. On this news, AeroVironment’s stock declined the following day by nearly 30% to close at $57.98/share causing significant losses to shareholders at the time.
