AYI — FY2026 Financial Report Analysis

Overview

Acuity Inc. (formerly Acuity Brands) closed its fiscal year on August 31, 2026 with net sales of $4.64 billion, up 6.8%, and diluted EPS of $17.05, up 36.1%. Most of that gap between sales growth and profit growth is not the business suddenly getting much more profitable. The sales gain came mainly from a full twelve months of QSC, the audio-video-control maker bought on January 1, 2025 (only eight months were in last year's numbers). The profit gain was inflated by $51.3 million of refunded tariffs booked this year and by roughly $84 million of one-time costs that weighed on last year. Underneath, the core lighting business shrank slightly, while the smaller Intelligent Spaces segment carried the growth.

The numbers

Segment sales add up to slightly more than the company total because of $41.2 million of sales between the two segments that are eliminated on consolidation. Operating margin is the share of sales left after running the business (factories, salaries, selling costs) but before interest and tax.

Takeaway: Acuity is now a two-speed company. Lighting, still about three-quarters of sales, shrank 1.0% and its adjusted profit fell 2.5%; the building-technology segment (AIS) grew 16.6% in the fourth quarter even with QSC in both years, and earned a 23.0% adjusted margin. The 36% EPS jump is mostly tariff refunds and easy comparisons; roughly 10% is the honest growth rate.

Two segments moving in opposite directions

Acuity Brands Lighting (light fixtures and controls for offices, schools, warehouses and the like) had sales down 1.0% to $3.58 billion. The 10-K attributes this to "lower net sales within the direct sales network and the OEM and other channel," partly offset by higher sales through independent sales agents and corporate accounts. Even so, ABL's reported operating profit rose 5.6% to $623.5 million and its margin improved from 16.4% to 17.4%. The filing explains the gross-profit gain with "lower net tariffs cost, including $38.2 million in IEEPA refunds, lower material costs, and lower quality costs." Take the refund away and the picture flips: the company's own adjusted ABL operating profit fell 2.5% to $646.0 million, with adjusted margin down 20 basis points to 18.1% (a basis point is one-hundredth of a percentage point). In the fourth quarter alone, ABL sales slipped 0.4% and adjusted operating profit fell 7.1%.

Acuity Intelligent Spaces (Distech building-management systems, the Atrius software platform, and now QSC's Q-SYS audio, video and control platform) grew sales 44.8% to $1.11 billion. The 10-K credits "the acquisition of QSC as well as higher net sales of Distech products." Because QSC joined on January 1, 2025, the full-year growth rate mixes in four extra months of an acquired business. The cleaner signal is the fourth quarter (June to August), when QSC was in both years: AIS sales still rose 16.6% to $297.6 million. AIS gross margin climbed from 55.5% to 61.3% and operating margin from 10.0% to 16.9%, partly because last year carried a $29.6 million inventory accounting charge from the QSC deal (acquired inventory gets marked up to fair value, which then flows through cost of sales as it is sold) and this year included $13.1 million of tariff refunds. On the company's adjusted basis, AIS margin went from 21.5% to 23.0%.

What the headline numbers hide

• Tariff refunds are a one-time gain. After a February 20, 2026 Supreme Court ruling on tariffs imposed under the International Emergency Economic Powers Act (IEEPA) and a March 2026 Court of International Trade ruling that importers are owed refunds, Acuity booked $51.3 million of refunds as a reduction in cost of products sold ($38.2 million in ABL, $13.1 million in AIS; $44.9 million of it in the fourth quarter). At the year's 21.9% tax rate that is roughly $40 million after tax, or about $1.29 per share by our arithmetic. It will not repeat.
• Last year's comparison was depressed by one-offs. Fiscal 2025 absorbed $29.6 million of QSC inventory fair-value charges, $23.8 million of acquisition professional fees and a $30.9 million non-cash pension settlement charge (booked in miscellaneous expense), about $84 million pre-tax in total, partly offset by an $8.2 million one-time tax benefit. None of these recurred. The pension item alone explains why miscellaneous expense fell from $41.7 million to $7.4 million.
• GAAP vs adjusted gap. Adjusted EPS ($19.90) is $2.85 above GAAP EPS ($17.05). The company adds back $93.1 million of amortization of acquired intangibles (mostly QSC's Q-SYS technology), $49.5 million of share-based pay and $23.7 million of special charges, and subtracts the $51.3 million tariff refund. Stock pay is a real, recurring cost, so the adjusted figure flatters the business somewhat; the amortization add-back is more defensible, since it reflects the price paid for QSC rather than an ongoing cash cost.
• Special charges keep recurring. $23.7 million this year (productivity actions in product portfolio, supply chain, footprint and labor) after $29.7 million last year, including $17.8 million in the fourth quarter alone. Two years in a row of "special" charges is closer to a normal cost of running the restructuring than a one-off.
• Cash conversion was strong, with help. Operating cash flow of $825.6 million was 1.55x net income. The 10-K attributes the rise to "higher profit, including $51.3 million of received tariff refunds, and lower income tax payments." Inventory fell 14.5% to $450.4 million (a $74.7 million cash release) while sales rose 6.8%; receivables rose 6.4%, in line with sales. Capital spending was $77.7 million, leaving about $748 million of free cash flow.
• Buybacks added a little to EPS growth. Diluted shares fell 1.5% to 31.15 million after $287.2 million of repurchases (about 0.9 million shares). Net income rose 34.0% versus EPS up 36.1%, so the buyback contributed roughly 2 points. A higher tax rate (21.9% vs 20.7%) and higher net interest expense ($25.6 million vs $22.0 million, because interest income fell as cash was used) worked slightly against EPS.
• No numeric outlook. Neither the 10-K nor the October 1 earnings release gives sales or EPS guidance for fiscal 2027, so there is no forecast to hold management to.

Balance sheet and capital allocation

Acuity repaid the remaining term loan it took to buy QSC, partly using a new five-year $800 million credit facility signed May 8, 2026. At year-end it had $697.4 million of debt (the 2.150% notes due 2030 plus $200.0 million drawn on the new facility) against $636.3 million of cash, so net debt was about $61 million. The 10-K says the $200.0 million revolver balance was voluntarily repaid in September 2026. Dividends rose to $0.77 per share for the year ($23.8 million total), and the earnings release says the dividend was increased 18%. Management lists acquisitions second among its capital-allocation priorities, after reinvesting in the business, and a near-zero net-debt balance sheet leaves room for another deal.

Outlook

With no formal guidance, the trajectory has to be read from the segments. In fiscal 2027 there is no QSC acquisition to lap and no tariff refund to repeat, so reported growth should drop toward the underlying rate: the fourth quarter showed total sales up 2.9%, ABL flat and AIS up 16.6%. If lighting stays flat and AIS keeps growing in the mid-teens, AIS's rising share of sales (24% this year) should lift group margins, because AIS earns a higher adjusted margin (23.0%) than ABL (18.1%). The risk sits in lighting: ABL's adjusted profit fell in both the full year and the fourth quarter, and the 10-K points to weaker direct-sales and OEM channels. For fiscal 2027, the two numbers to watch are whether AIS keeps growing double digits without acquisitions, and whether ABL's adjusted margin stabilises once tariff costs and refunds wash out. A reported EPS decline next year would not by itself signal a weaker business, since this year's GAAP figure includes about $1.29 per share of refunds.
