Portnoy Law Firm Announces Class Action on Behalf of Microsoft Corporation Investors

The Portnoy Law Firm has announced a class action lawsuit on behalf of Microsoft investors who purchased securities between May 1, 2025 and January 28, 2026. The lawsuit alleges that Microsoft misrepresented Copilot's capabilities and functionality, which allegedly suffered from severe issues causing user adoption to decline. On January 28, 2026, Microsoft revealed disappointing Azure growth and disclosed that Microsoft 365 Copilot premium customers totaled only 15 million, materially below analyst estimates, causing the stock to drop 10% ($48.13 per share).
