A ranked snapshot analyzing year-over-year language changes in SEC 10-K annual filings for June 16, 2026. Two companies qualified: Sonoma Pharmaceuticals (ranked 1st with a full-filing similarity score of 0.985) and La-Z-Boy Inc (0.997). Sonoma's key changes include a push into consumer markets, a new Nasdaq delisting risk warning, and increased equity dilution from rising option grants. La-Z-Boy's main change is the addition of a Chief Information Security Officer with formal reporting lines to the CIO and Audit Committee. The methodology is grounded in academic research (Cohen et al., 'Lazy Prices', 2020) showing that companies making significant filing changes have historically underperformed, while stable-language filers earned positive abnormal returns.
