Mateen Justin 4

What Happened

• Justin Mateen, a director of American Bitcoin Corp. (ABTC), had 254,778 restricted stock units (RSUs) vest and convert into 254,778 shares of Class A common stock on June 22, 2026. The Form 4 shows a corresponding “Disposed” entry for the same 254,778 shares at $0, meaning no cash proceeds were reported from that disposition.

Key Details

• Transaction date: 2026-06-22 (reported on Form 4 filed 2026-06-24).
• Reported transactions: conversion/exercise of a derivative (code M) resulting in 254,778 shares acquired; a matching disposed entry for 254,778 shares at $0.
• Price/Value: Acquired via conversion (no purchase price reported); disposed at $0 (no cash proceeds shown).
• Shares owned after transaction: Not included in the provided excerpt of the filing.
• Footnotes: F1–F3 state these were RSUs that vested and converted one-for-one into Class A shares, that RSUs could be settled in stock or cash at the issuer’s discretion, and that the RSUs vested on the date of the issuer’s 2026 Annual General Meeting.
• Timeliness: Filing date is 2026-06-24 for a 2026-06-22 transaction (filed within the typical two-business-day Form 4 window).

Context

• The entries reflect RSU vesting and conversion rather than an open-market buy or sale. A disposed entry at $0 in these cases commonly reflects shares surrendered or withheld (or cash settlement) tied to RSU payout or tax withholding, consistent with the issuer’s note that RSUs could be settled in stock or cash — the filing itself does not specify the exact mechanics. This type of transaction is routine for equity compensation and does not, by itself, indicate a buy or sell signal from the insider.
