Notice of Partial Revision to the Stock Compensation Plan

Background and Purpose of Stock Compensation Plan Revision

Komatsu Wall Industrial has resolved to partially revise its stock compensation plan “Stock Benefit Trust (BBT)” for directors (excluding non-executive directors) and executive officers, changing it to “Stock Benefit Trust with Restricted Stock (BBT-RS).” The purpose of this revision is to have directors and others hold restricted stock while in office, granting them rights similar to shareholders and thereby enhancing awareness towards improving corporate value. The proposal will be submitted at the shareholders meeting on June 18, 2026.

Overview and Operation of the Plan

This plan involves the Company contributing cash to a trust, which acquires shares to provide stock or cash to directors and others based on granted points. The shares granted to directors and others while in office will have transfer restrictions until their resignation. The maximum points granted per fiscal year are 42,000 points (of which 24,000 are for directors), with an upper limit of 210,000 shares on a stock count basis. The trust period starts from August 2016 and continues until termination. Voting rights of shares within the trust property will not be exercised. Non-executive directors are excluded, but transitional measures allow existing granted points to be transferred.
