What Management Said
Read the full Q4 2025 transcript ↗Today's call will include updates on our strategic progress and on our fiscal 2025 Fourth Quarter and Full Year performance. We grew net sales, expanded our adjusted operating profit and adjusted operating profit margin, and increased our adjusted diluted earnings per share. Throughout fiscal 2025, we have demonstrated our ability to deliver growth and consistent operating performance that created stakeholder value and compounded shareholder wealth. Acuity Brands Lighting delivered sales growth and improved adjusted operating profit and adjusted operating profit margin in the fourth quarter.
As part of our ABL growth algorithm, we are making organic investments for future growth, prioritizing verticals where we have not historically competed or where we are underpenetrated. We have transformed the company from principally a luminaires business to a data and controls and luminaires business and positioned ourselves well for long-term growth. Our focus in AIS will continue to be on growth with the opportunity for margin expansion. We grew net sales, improved our adjusted operating profit and adjusted operating profit margin, and increased our adjusted diluted earnings per share.
This was driven by growth in both business segments and includes three months of QSC sales. This improvement was due to the growth of AIS, including the acquisition of QSC, and the result of actions taken at ABL to control operating expenses. Adjusted operating profit margin during the quarter expanded to 18.6%, an increase of 130 basis points from the prior year. Through our investment policies and capital allocation decisions, these pension plans were overfunded.
What went well
- Total Acuity net sales reached $1.2 billion in the fourth quarter, up $177 million or 17% over the prior year, driven by growth in both business segments and three months of QSC sales.
- Adjusted operating profit grew to $225 million, up $47 million or 26%, and adjusted operating profit margin expanded 130 basis points to 18.6%, reflecting AIS growth and ABL operating-expense actions.
- Adjusted diluted earnings per share was $5.20, an increase of $0.90 or 21% over the prior year.
- Acuity Brands Lighting expanded its adjusted operating profit margin 210 basis points to 20.1% and grew adjusted operating profit $22 million to $194 million on the strength of third-quarter cost actions and productivity, with the independent sales network up 4% or $25 million.
- Acuity Intelligent Spaces grew sales $171 million to $255 million with a 21.4% adjusted operating profit margin, as legacy Atrius and Distech grew about 13% and QSC grew about 15% year-over-year, and management noted QSC picked up roughly 500 basis points of margin in eight months.
- The company allocated capital effectively across fiscal 2025, generating $601 million of operating cash flow, raising the dividend 13%, repurchasing about 436,000 shares for roughly $119 million, and repaying $200 million of its term loan.
What went wrong
- ABL sales grew only 1% ($7 million) to $962 million, as growth in the independent sales network was largely offset by declines in corporate accounts and the direct sales network, and the sequential fourth-quarter ramp came in below normal seasonality.
- The company recorded an approximately $31 million non-cash charge to de-risk its U.S. and Mexico qualified pension plans, and flagged an additional roughly $10 million non-cash GAAP charge expected in the first quarter of fiscal 2026 for the U.K. plan transfer.
- The combination of higher tariff costs and offsetting price increases is neutral on dollars but negative on margin percentage, creating an estimated 50-100 basis point (up to roughly 100 bps on a full-year basis) headwind to ABL margins that must be digested over time.
- Management is not modeling any improvement in the lighting end market and characterized the environment as tepid and directionless, with the ABL low-single-digit 2026 sales guide assuming the market stays flat to down.
- AIS margin expansion is expected to pause in the near term because, when faced with a choice between expanding margins or continuing growth, management will deliberately invest for growth rather than expand AIS margins over the next 12 months.
- Day's inventory has been rising, elevated by higher tariff-driven inventory cost and deliberate pre-buys to protect against increasing tariffs, and full-year operating cash flow was $18 million lower than the prior year on acquisition items and tariff-payment/inventory timing.

Earnings Call Themes & Trends
| Topic | Previous mention | Current period | Trend |
|---|---|---|---|
| QSC integration and AIS build-out | QSC acquired and being integrated; expected to move QSC margins toward legacy AIS levels | Integration going well after ~eight months; QSC gained ~500 bps of margin (mid-teens to low 20s) over two quarters and grew ~15%; AIS now a larger part of the company with a consistent M&A pipeline plus organic expansion (e.g., expanded India experience center). | — |
| Data interoperability and monetization (Atrius Data Lab) | Early vision of consolidating the data state of a built space across Atrius, Distech, and QSC | Near-term value comes through outcomes and experiences delivered on strong control platforms; specific software opportunities in market now with more over 12-24 months; data monetization to manifest as accelerating software revenue and possibly data-specific products over time. | — |
| Tariffs, supply chain, and China de-risking | Prudent to evaluate the second half amid changing tariff policy; supply-chain and price actions underway | Majority of tariff-exposed material moved away from China within a month of the April 2 announcements; total China exposure down to ~20% of a prior peak; pricing used strategically (low-to-mid single digits) to offset tariff dollars, biased toward share gains over incremental margin. | — |
| ABL growth algorithm (market, share, new verticals) | Grow with the market, take share, enter new verticals | Delivering consistently in a tepid market; new verticals (healthcare via Care Collection/Nightingale, refuel, sport lighting) worth ~50-100 bps to the top line; Contractor Select and specifier brands taking share. | — |
| Margin trajectory vs. growth investment | Continued margin expansion across both segments | ABL keeps driving productivity-led margin gains but absorbs a ~100 bps tariff/price percentage headwind near term; AIS deliberately prioritizes growth over margin expansion for the next 12 months while margins still trend higher long term. | — |
| Capital allocation | Grow organically and through acquisitions, reward shareholders, don't grow the balance sheet as fast | Invested over $1.2B in acquisitions and $68M capex, raised the dividend 13%, repurchased ~436K shares (~$119M), and repaid $200M of term debt; since Q4 FY2020 repurchased ~10M shares (~25% of then-outstanding) at an average ~$150 funded by organic cash flow. | — |
Q&A Summary
Chris Snyder (Morgan Stanley) asked, roughly eight months after the QSC acquisition, about the M&A pipeline and which categories within the smart-building ecosystem are attractive.
Ashe said Acuity has a consistent pipeline of potential acquisitions that would expand its ability to consolidate the data state of a built space (how a building operates, the experiences in it, who is in it), alongside organic expansion opportunities, and that the path of travel for Intelligent Spaces is clear both for deploying capital and growing organically.
Chris Snyder (Morgan Stanley) followed up on ABL's fourth-quarter sequential ramp coming in below seasonality, asking whether it reflected the Q3 pull-forward, softening end markets, or channel-inventory dynamics heading into fiscal 2026.
Ashe said that taking the third and fourth quarters together, ABL landed exactly where management expected after the tariff-driven supply-chain and cost actions; the project business (independent plus direct networks) stayed strong while the lumpier corporate-accounts business was down for the quarter and year, and he reiterated the belief that ABL outperformed the industry.
Tim Wojs (Baird) asked about the key milestones to watch as Acuity integrates the front of the house (QSC) with the back of the house (Distech and Atrius) into a more wholesome AIS solution.
Ashe said each of the three businesses will keep developing organically and taking share, while Atrius Data Lab integrates their data (IT/OT, front/back of house); over time customers will begin commingling products and articulating new capabilities they hadn't realized were possible from combining the hardware with the data and software layer.
Tim Wojs (Baird) asked a two-part guidance question on how much price is embedded in the low-single-digit ABL guide and whether an implied ~17-18% adjusted EBIT margin is the right ballpark.
Holcom said ABL pricing actions have totaled about low-to-mid single digits, taken strategically (some prices up, some down across Contractor Select, Design Select, and Made to Order) to offset the dollar impact of tariffs rather than applied uniformly. Ashe used the full-year call to highlight the dramatic margin improvement since fiscal 2019/2020 and announced Acuity will now disclose both gross and operating profit margin at the segment level.
Ryan Merkel (William Blair) asked whether there are any signs orders and demand are improving, or whether lower interest rates are needed before the lighting market lifts.
Ashe said management continues to grind out performance without economic stability and is modeling more of the same with no improvement built in; he emphasized the ABL growth algorithm delivers results regardless of context, and any market tailwind would simply be an accelerant on top.
Ryan Merkel (William Blair) also pressed on gross margins, noting the Street models 2026 down, and asked whether the prior 50% gross-margin target via productivity is still reasonable.
Ashe said the whole company keeps expanding on mix and improved ABL performance, but the tariff-cost/price-increase combination is dollar-neutral and margin-percentage-negative to the tune of roughly 50-100 basis points, which claws back some ABL margin expansion for a period while the longer-term strategy and expectations stay intact.
Joe O'Dea (Wells Fargo) asked about QSC's fourth-quarter margins (appearing around 20% versus legacy AIS near 23%) and the timeline to align QSC with legacy margins.
Holcom said Acuity is pleased with QSC's progress, having brought its performance closer to the legacy business over two quarters through strong sales growth and adoption of the better, smarter, faster operating system to drive productivity without adding cost; she said QSC remains a margin-expansion opportunity over time, but the AIS focus stays on growth.
Joe O'Dea (Wells Fargo) also asked Ashe to elaborate on the cost and supply-chain actions, including where China now sits as a percentage of sourcing.
Ashe said Acuity moved the majority of tariff-exposed material away from China (to other Asia and within its own footprint) within the first month after the April 2 announcements, bringing total China exposure down to roughly 20% of a prior peak; on ABL, the company reevaluated operating expenses, accelerated productivity projects, and eliminated a portion of employees as permanent cost changes.
Christopher Glynn (Oppenheimer) asked, given listless markets and a confident revenue guide, where in the commercial RFP environment Acuity sees the most competitive momentum beyond product.
Ashe pointed to new verticals (healthcare, refuel, and sport lighting) adding roughly 50-100 basis points to the top line, strong fourth-quarter performance from the Contractor Select portfolio where Acuity is pressing its advantage, and renewed strength in its specifier brands, all contributing to share gains in a tepid environment.
Brian Lee (Goldman Sachs) asked about the directional margin story, whether ABL is holding the line while AIS builds for growth, and whether AIS gross margins could backslide in 2026.
Ashe said ABL will keep driving productivity-led margin gains while absorbing a roughly 100-basis-point tariff/price percentage headwind, and that AIS, growing low-to-mid teens, will invest for growth when forced to choose between growth and margin; he noted Acuity added ~500 basis points of margin to QSC in eight months and expects AIS margins to keep rising over time.
Brian Lee (Goldman Sachs) also asked about data-monetization opportunities in AIS and whether they could be quantified or broken out.
Ashe said the near-term impact comes through outcomes delivered on Acuity's strong control platforms, with specific software opportunities in the market now and more coming over the next 12-24 months; longer term, data monetization should manifest as accelerating software revenue and potentially data-specific products, but he did not commit to breaking it out.
Jeffrey Sprague (Vertical Research Partners) asked whether Acuity's tariff counter-actions leave it over-priced for tariffs it is no longer exposed to, creating an embedded margin opportunity, and whether any 2025 cost actions are temporary and need to return in 2026.
Ashe said Acuity has been conservative, mitigating tariffs through productivity and sourcing transitions first and pricing second, and would bias any excess toward taking share rather than banking incremental margin; he said the 2025 cost actions are permanent (not short-term Band-Aids), while ongoing OpEx will keep rising with technology investment that drives productivity. Holcom added that elevated inventory reflects higher tariff-driven cost plus deliberate pre-buys and should draw down over the year.
