ACUITY INC. (DE)

On July 1, 2026, Neil M. Ashe, our Chairman, President and Chief Executive Officer, adopted a Rule 10b5-1 trading arrangement for (i) the sale of shares of common stock of the Company and (ii) the exercise of employee stock options and sale of the underlying shares of common stock of the Company. The plan has an effective date of October 5, 2026, though no trading will occur until permitted in compliance with applicable SEC laws, rules, and regulations. The plan has an expiration date of March 31, 2028. The plan is intended to satisfy the affirmative defense of Rule 10b5-1(c) of the Exchange Act. Pursuant to the plan: (i) the aggregate number of shares of common stock of the Company to be sold is not to exceed (a)33,641 shares, plus (b) 100 percent of the net issued shares received as a result of restricted stock unit and performance stock unit vestings on October 24, 2026 and October 24, 2027, for which the aggregate number of shares to be sold is dependent on the terms and conditions of, and taxes on, the applicable units, and therefore, is indeterminable at this time; and (ii) the aggregate number of employee stock options to be exercised and underlying shares of common stock of the Company to be sold is not to exceed 77,720 shares.

Other than as described above, during the fourth quarter of fiscal 2026, none of our directors or Section 16 officers adopted or terminated any “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement” (as each term is defined in Item 408(a) of Regulation S-K).
