Summary

The suit alleges misstatements occurred between May 1 2025 and January 28 2026.

History

Historical Context

After the Enron collapse spurred hearings from December 2001 to April 2002, Congress passed the Sarbanes-Oxley Act on July 30 2002, with a Senate vote of 99-1 and co-sponsors Senator Paul Sarbanes and Rep. Michael Oxley. The law forces CEOs and CFOs to certify filings, a rule now invoked as a Michigan pension fund and Seattle court sue Microsoft’s Satya Nadella and Amy Hood over AI-related disclosures.
