Block, Inc. Director Anthony Eisen Files Form 144 for Routine 6,000 Share Sale

Executive Summary

On October 27, 2026, Block, Inc. director Anthony Mathew Eisen submitted a Form 144 notice proposing the sale of 6,000 shares of common stock through Morgan Stanley Smith Barney LLC, with an estimated aggregate market value of $448,740.00 (approximately $74.79 per share).

Transaction & Plan Background

• Trading Plan: The planned sale is executed pursuant to a Rule 10b5-1 trading plan adopted on March 2, 2026.
• Origin of Shares: The securities were acquired on January 31, 2022, from the issuer as restricted stock.
• Historical Selling Pattern: Eisen has been selling regular 6,000-share tranches on almost every trading day over the preceding three months, alongside a larger single sale of 41,000 shares on August 5, 2026.

Market & Trading Significance

• Significance Level: Low
• Rationale: The proposed sale represents a negligible fraction of Block's 540,816,000 shares outstanding. Given that it is executed systematically under a pre-established Rule 10b5-1 plan, it reflects routine diversification rather than an opportunistic signal regarding company fundamentals.
