Income Tax Status	12 Months Ended
Dec. 31, 2025
EBP Plans
EBP, Tax Status [Line Items]
Income Tax Status	Income Tax Status The AYI Plan, ABL Plan, and Holophane Plan obtained their latest determination letters on August 12, 2013, July 10, 2013, and May 29, 2014, respectively, in which the IRS stated these plans are qualified under Section 401(a) of the Internal Revenue Code ("IRC"). The Plans have been amended since requesting the latest determination letters, and the Plan Administrator believes the Plans are currently designed and being operated in compliance with the applicable requirements of the IRC. Thus, the Plans and related trust continue to be tax-exempt. Therefore, no provision for income taxes is included in these financial statements. U.S. GAAP requires plan management to evaluate uncertain tax positions taken by the Plans. The financial statement impact of a tax position is recognized when the position is more likely than not, based on its technical merits, to be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plans and has concluded that as of December 31, 2025, there are no uncertain positions taken or expected to be taken. The Plans have recognized no interest or penalties related to uncertain tax positions. The Plans are subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

Fair Value Measurements

12 Months Ended

Dec. 31, 2025

EBP, Investment, Fair Value and NAV [Line Items]

In accordance with Accounting Standards Codification Topic 820, Fair Value Measurement ("ASC 820"), fair value measurements are determined using an exit price based on the assumptions a market participant would use in pricing an asset or liability. ASC 820 establishes a three-tiered hierarchy making a distinction between market participant assumptions based on (i) observable inputs such as quoted prices in active markets (Level 1), (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2), and (iii) unobservable inputs that reflect the Plans' best estimate of what market participants would use in pricing an asset or liability including consideration of the risk inherent in the valuation technique and the risk inherent in the inputs to the model (Level 3).

Level 1 (Quoted market prices in active markets for identical assets)

Mutual Funds - valued using the net asset value ("NAV") of shares held at year end as reported by the fund. Mutual funds held by the Acuity DC Trust are open-end mutual funds that are registered with the Securities and Exchange Commission.

Self-Directed Brokerage Accounts - valued at the closing price reported by the fund or in the market where such investments are primarily traded.

Acuity Stock Fund - valued at the last sales price in the market where such securities are primarily traded. If the last sales price is not available, the security is generally valued at the closing bid price obtained from the primary exchange.

Our unallocated cash and cash equivalents, which are required to be carried at fair market value and measured on a recurring basis, were $14,973 as of December 31, 2025. We had $157,242 of unallocated cash and cash equivalents outstanding as of December 31, 2024.

Assets Excluded from Fair Value Hierarchy

The common/collective trusts held by the Acuity DC Trust are valued using the NAV provided by the trustee, which are based on the fair value of the underlying investments held by a fund less its liabilities. The common/collective trusts' NAVs are used as a practical expedient to estimate fair value since it is not probable that the funds will sell the investment for an amount different than the reported NAV. There are currently no redemption restrictions or unfunded commitments on these investments. Generally, redemptions of the fund units for investments in this category may be made each business day, based upon a transaction price per unit that is substantially equivalent to net asset value per share as of the close of the previous business day.

The following table presents information about the Acuity DC Trust's investments that are carried at fair value as of December 31, 2025 and 2024:


	Fair Value Measurements as of:
	December 31, 2025				December 31, 2024
	Total Fair Value		Level 1		Total Fair Value		Level 1
Mutual funds	$	268,971,306	$	268,971,306	$	238,564,816	$	238,564,816
Acuity stock fund	14,081,073		14,081,073		11,854,007		11,854,007
Self-directed brokerage accounts	51,679,977		51,679,977		53,351,894		53,351,894
Common/collective trust	337,923,055		N/A		205,848,129		N/A
Total investments at fair value	$	672,655,411			$	509,618,846

No transfers between the levels of the fair value hierarchy occurred during the plan years presented. In the event of a transfer in or out of a level within the fair value hierarchy, the transfers would be recognized as of the end of the plan year.

EBP, Description of Plan [Line Items]

Description of the Plans

General

The financial positions and changes in net assets of the Acuity Inc. 401(k) Plan (the "AYI Plan"), the Acuity Brands Lighting, Inc. 401(k) Plan for Hourly Employees (the "ABL Plan"), and the Holophane Division of Acuity Brands Lighting 401(k) Plan for Hourly Employees Covered by a Collective Bargaining Agreement (the "Holophane Plan") (collectively, the "Plans") are included in the accompanying financial statements. The investment assets of the Plans are included in the Acuity Inc. Defined Contribution Plans Master Trust (the "Acuity DC Trust"). The Plans are subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

Refer to the respective plan agreement for additional information about the Plans' eligibility, funding, allocation, vesting, and benefit provisions.

Eligibility and Forfeitures

Each of the Plans is a defined contribution plan. The Plans cover substantially all U.S. salaried, commissioned, and union and non-union hourly employees of Acuity Inc. and its subsidiaries ("Acuity," "we," "our," "us," or the "Company"). Employees may immediately participate upon attaining the age requirement of each respective plan.

The Plans provide that forfeitures of Company contributions may be used to pay plan administrative expenses or reduce future Company contributions. Forfeited nonvested accounts totaled $291,500 and $386,131 at December 31, 2025 and 2024, respectively. Employer contributions were reduced by forfeited nonvested accounts of $786,875 for the year ended December 31, 2025. No plan expenses were paid using forfeited nonvested accounts during the year ended December 31, 2025.

In the event of the cessation of operation of a plant or the discontinuance of a component of our business, plan participants identified for separation from the Company shall automatically become fully vested in employer contributions upon termination.

Administration

Administration of the Plans is the responsibility of our Investment Committee, members of which are designated by the President and Chief Executive Officer of the Company. Certain administrative expenses of the Plans were paid by the Company during the year ended December 31, 2025. The Investment Committee determines the appropriateness of the Plans' investment offerings and monitors investment performance.

Notes Receivable from Participants

Participant loans are reflected as notes receivable from participants on the Statements of Net Assets Available for Benefits. Participants may borrow the lesser of 50% of their vested balance or $50,000 (reduced by the participant's highest outstanding loan balance from the twelve months prior to the loan request). Participants agree to loan repayment terms upon endorsement of the borrowed funds. Participants within the AYI Plan and the ABL Plan may have up to two outstanding general-purpose loans during a calendar year. Participants within the Holophane Plan may have outstanding one general-purpose loan and one residential loan issued for the purchase of a primary residence during a calendar year. The loan interest rate is a fixed rate at the time the loan is taken out. The interest rate is set at one percent above the prime rate, as defined per the plan.

Loan repayments must be substantially equal in amount over the term of the loan and must be made by payroll deduction on an after-tax basis. General-purpose loans must be repaid within five years, and residential loans must be repaid within ten years.

Loan repayments may be suspended at our discretion for a period of not more than twelve months if a participant is on unpaid leave of absence, disability, or military service. Upon return, the loan will be amortized over the remaining initial loan repayment period.

Plan Termination

Although we intend for the Plans to be permanent, the Plan agreements provide us the right to discontinue contributions or to terminate the Plans at any time subject to the provisions of ERISA. In the event of a plan termination, participants shall be 100% vested in the balance of their accounts and their proportionate share of any future adjustments or forfeitures.

Parties-In-Interest and Related-Party Transactions

As of December 31, 2025 and 2024, the percentage of the Plans' net assets invested in the Acuity stock fund was approximately 2.0% and 2.1%, respectively. As described in Note 2 — Summary of Accounting Policies of the Notes to Financial Statements, the Plans paid certain expenses related to plan operations and investment activity to various service providers. The Plans also have outstanding notes receivable from participants. These transactions are party-in-interest transactions under ERISA.

Vesting

Participants are vested immediately in their contributions and the related earnings. Participants in the AYI Plan and the ABL Plan vest in employer contributions to their accounts ratably over a five-year service period. Participants in the Holophane Plan vest in our contributions to their accounts immediately upon the third anniversary of their hire date.

Payments of Benefits

On termination of service due to death, disability, or retirement, participants may elect to receive either a lump sum amount equal to the value of the vested interest in their accounts or annual installments over a ten-year period. For termination of service for other reasons, participants may receive the value of the vested interest in their accounts as a lump-sum distribution.

Participant Accounts

Each participant’s account is credited with the participant’s contributions and our matching contributions, as well as the applicable portion of net earnings/losses generated by the investment fund(s) selected by the participant. Net earnings/losses for each investment fund consist of both realized and unrealized gross earnings/losses, which are adjusted to incorporate fund management expenses specific to each investment fund. Additionally, participants are charged a quarterly administrative recordkeeping fee. We directly pay certain expenses of maintaining the Plans, which are excluded from these financial statements. Fees related to the administration of notes receivable from participants are charged directly to the participant's account. Participants are entitled to the benefits that can be provided from their vested accounts.

Contributions

The basis for determining Company contributions is outlined in the following table:


Plan Name			Employer Contributions
AYI Plan			Matching contribution of 60% up to 6% of participant compensation contributed. New hires are automatically enrolled at 3% contribution to the plan.
ABL Plan			Teamsters Local Union 673, IBEW Local 953, and non-union hourly associates have a matching contribution of 60% up to 6% of participant compensation contributed.
			IBEW Local 613, IBEW Local 1048, IBEW Local 1710, and Teamsters Local Union 728 associates participating in the plan do not receive a matching contribution.
Holophane Plan			USW Local Nos. 4, 105, and 525 - Participating associates hired prior to August 5, 2002 receive an employer matching contribution of 30% up to 6% of compensation contributed, plus an additional basic employer contribution of 5% of annual compensation. Participating associates hired on or after August 5, 2002 receive an employer matching contribution of 60% up to 6% of compensation contributed.

Under all of the Plans, participants are able to contribute up to 100% of their compensation. Participants direct the investment of their contributions into various investment options offered by the Plans. Additionally, participants who

have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. Participants may also contribute amounts representing distributions from other qualified plans. Participants may make traditional or Roth contributions in the Plans. Contributions are subject to certain Internal Revenue Service ("IRS") limitations.

Plan Amendments

Effective December 29, 2025 , the Plans were amended and restated primarily to change the employer’s legal name from Acuity Brands, Inc. to Acuity Inc and to merge the QSC, LLC 401(k) Retirement Savings Plan (the "QSC Plan") into the Plans. Refer to Note 9 — Acquisitions

Summary of Accounting Policies (Policies) - EBP Plans	12 Months Ended
Summary of Accounting Policies (Policies) - EBP Plans	Dec. 31, 2025
EBP, Accounting Policy [Line Items]
Basis of Accounting	Basis of Accounting The accompanying financial statements are prepared on the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP").
Investments	Investments The investments in the Acuity DC Trust are subject to certain administrative guidelines and limitations as to the type and amount of securities held. Fund assets are allocated to selected independent investment managers to invest under these guidelines. Certain investments of the Acuity DC Trust are stated at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). Stable value funds are listed at contract value, which is defined as the amount participants would receive if they were to initiate transactions under the terms of the ongoing plan. Refer to Note 3 — Acuity DC Trust and Note 5 — Fair Value Measurements of the Notes to the Financial Statements for further discussion. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the dividend date. Net investment gain from Acuity DC Trust includes the Plans' gains and losses on investments bought and sold as well as held during the year. The Acuity DC Trust holds investments in the Invesco Stable Value Fund, which holds synthetic guaranteed investment contracts ("synthetic GICs") and a diversified portfolio of investments, including units of collective trust funds held in the name of the Acuity DC Trust. Refer to Note 4 — Stable Value Investments of the Notes to the Financial Statements for further discussion.
Notes Receivable from Participants	Notes Receivable from Participants The notes receivable from participants represent participant loans, which are carried at principal amounts outstanding plus accrued but unpaid interest. Interest income and fees recognized as administrative expense are recorded on the accrual basis. No allowance for credit losses has been recorded as of December 31, 2025 and 2024. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default, the participant loan balance is reduced, and a benefit payment is recorded.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
Contributions	Contributions Contributions to the Plans from participants, and when applicable, from the Company are recorded in the period that payroll deductions are made from Plan participants.

For the year ended December 31, 2025, total interest income, dividend income, and net appreciation in investments were $1,336,091, $15,575,037, and $68,577,407, respectively.

Summary of Accounting Policies	12 Months Ended
Summary of Accounting Policies	Dec. 31, 2025
EBP Plans
EBP, Accounting Policy [Line Items]
Summary of Accounting Policies	Summary of Accounting Policies Basis of Accounting The accompanying financial statements are prepared on the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). Investments The investments in the Acuity DC Trust are subject to certain administrative guidelines and limitations as to the type and amount of securities held. Fund assets are allocated to selected independent investment managers to invest under these guidelines. Certain investments of the Acuity DC Trust are stated at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). Stable value funds are listed at contract value, which is defined as the amount participants would receive if they were to initiate transactions under the terms of the ongoing plan. Refer to Note 3 — Acuity DC Trust and Note 5 — Fair Value Measurements of the Notes to the Financial Statements for further discussion. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the dividend date. Net investment gain from Acuity DC Trust includes the Plans' gains and losses on investments bought and sold as well as held during the year. The Acuity DC Trust holds investments in the Invesco Stable Value Fund, which holds synthetic guaranteed investment contracts ("synthetic GICs") and a diversified portfolio of investments, including units of collective trust funds held in the name of the Acuity DC Trust. Refer to Note 4 — Stable Value Investments of the Notes to the Financial Statements for further discussion. Notes Receivable from Participants The notes receivable from participants represent participant loans, which are carried at principal amounts outstanding plus accrued but unpaid interest. Interest income and fees recognized as administrative expense are recorded on the accrual basis. No allowance for credit losses has been recorded as of December 31, 2025 and 2024. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be in default, the participant loan balance is reduced, and a benefit payment is recorded. Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Contributions Contributions to the Plans from participants, and when applicable, from the Company are recorded in the period that payroll deductions are made from Plan participants. Payments Benefit payments are recorded when paid. Expenses Investment-related expenses are included within Net investment gain from Acuity DC Trust on the Statements of Changes in Net Assets Available for Benefits. Additionally, participants are charged a quarterly administrative recordkeeping fee, which is included within Expenses on the Statements of Changes in Net Assets Available for Benefits. Certain investment funds provide for a revenue sharing arrangement with the Plans that provides for a portion of the fund expenses to be credited to the Plans to pay for certain administrative expenses that are incurred by the Plans. The Company directly pays certain expenses of maintaining the Plans, which are excluded from these financial statements. Fees related to the administration of notes receivable from participants and certain administrative fees are charged directly to the participant's account and are included in expenses.

Accordingly, we assumed sponsorship of the QSC Plan effective on such date. On September 15, 2025, the QSC Plan was fully merged into the AYI and ABL plans, resulting in the transfer of plan assets from the QSC Plan totaling $115,651,010 and $7,208,446, respectively.
