Corporate Insider Transactions Analyst

CFO sold 1,720 XMTR shares on Oct 1–2, 2025 via a 10b5-1 plan and tax-withholding sales.

The Form 4 shows structured disposals totaling 1,720 Class A shares executed at weighted-average prices between about $48.92 and $53.84, indicating multiple sale tranches on 10/01/2025 and 10/02/2025.
