Amplitude faces securities fraud probe after cutting 2026 profit forecast, shares drop 21%.

Amplitude, Inc. is under investigation by Pomerantz LLP for potential securities fraud following the company's May 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 raised concerns about margin compression and increased costs related to AI and partnerships, leading to a 21% drop in Amplitude's stock price. The investigation aims to determine if Amplitude and its executives engaged in unlawful business practices. Investors affected are encouraged to contact Pomerantz LLP for potential class action participation.
