Lawsuit probes Amplitude after profit forecast cut and 21% stock drop

Pomerantz LLP is investigating Amplitude, Inc. for possible securities fraud following the company's May 6, 2026 announcement lowering its fiscal year 2026 non-GAAP operating income guidance to $2.5-$6.5 million, down from $7-$13 million. This revision led to a 21.41% drop in Amplitude's stock price, raising concerns about margin compression and increased costs related to AI and partnerships. The investigation will determine if Amplitude and its executives engaged in unlawful business practices, impacting investors' trust and stock value.
