⚔️ Adversarial Opposing Case: Why the AMPH Bull Thesis Could Fail

Gideon Ashmere Forensic Desk →

Even with a 71/100 (B-) score, AMPH faces multiple-compression risk if 11.7x trailing P/E re-rate toward historical sector medians or if hyperscaler/enterprise customer concentration slows in upcoming 10-Q filings.

⚠️ Forensic Kill-Switch #1

Recent SEC filings added new risk-factor disclosures that warrant keeping an eye on margins.

⚠️ Forensic Kill-Switch #2

Dilution & Margin Drag: Cannibal Buyback (-2.64% YoY Shares) — any gross margin slip below 47.0% triggers an automatic RQD downgrade.

⚠️ Forensic Kill-Switch #3

Technical & Forensic Kill-Switch: A daily close below the 50D SMA ($24.76) or 200D SMA ($22.25) invalidates the momentum regime and cuts Target Base ($28.51) toward Bear Floor ($22.08).
