Director Karen Firestone buys 3.8K shares of AMLX at $13.51; stock now down 30.0% from 52-week high, company unprofitable with $-41.3M net income

Karen Firestone purchased 3,800 shares at $13.51 on 2026-05-21, increasing her holdings by 6.0% to 66,900 shares total. The purchase occurs as AMLX trades at $13.01, down 30.0% from its 52-week high of $18.60 and down 11.7% over the past 30 days. Notably, Firestone's prior two purchases at AMLX (2025-12-23 and 2024-09-05) both showed positive 90-day returns of 30.4% and 146.7% respectively, establishing a pattern of well-timed entries at this ticker. However, the company's fundamentals present significant headwinds: latest quarterly revenue is $0.00, full-year net income was $-41.3M, and annual revenue growth declined 100.0% year-over-year, indicating an unprofitable business in significant financial distress.
