What Happened

Stefano Langenbacher, Chief Technology Officer of Vivid Seats (SEAT), converted/treated derivative awards (RSUs) into common shares on June 11, 2026. The filing shows an aggregate 44,491 shares acquired via exercise/conversion of derivative awards. To cover tax withholding, 19,708 shares were surrendered/sold at $8.53 per share for total proceeds of $168,109. Additional derivative conversion/disposition lines (1,817; 4,448; and 38,226 shares) were recorded at $0.00, reflecting conversions/settlements of RSU-type awards rather than open-market sales.

Key Details

Transaction date: 2026-06-11; Form 4 filed 2026-06-15 (filed within the typical 2 business‑day window).
Reported sale for tax withholding: 19,708 shares at $8.53 = $168,109.
Other lines: 44,491 shares acquired (exercise/conversion, code M); 1,817, 4,448 and 38,226 shares listed as disposed at $0.00 (derivative conversions/settlements).
Footnotes: RSUs represent contingent rights to one share each (F1). Vesting schedules vary by grant (see F2–F4) with staggered quarterly vesting through 2027–2028; RSUs have no expiration date.
Shares owned after the transaction: not specified in the provided excerpt of the filing.

Context

These entries reflect RSU conversions/settlements and a tax-withholding disposition rather than an open-market investment sale; the cash generated ($168k) arose from withholding/sale to cover taxes.
Code meanings: M = exercise/conversion of a derivative (e.g., RSU to stock); F = shares withheld/surrendered to satisfy tax withholding.
Such routine post‑vesting withholding transactions are common and are not direct buy/sell signals about the insider’s market view.
