Acuity Inc. (AYI) reported fiscal fourth-quarter adjusted earnings of $5.77 per share. That cleared the $5.61 consensus but fell 0.5% short of the $5.80 Earnings Whisper number, a narrow miss of the bar investors actually cared about. Revenue of $1.244 billion grew 2.9% year over year but missed the $1.26 billion consensus by 1.2%. Earnings Whispers puts year-over-year earnings growth at 6.9%. The company's own adjusted comparison shows 11% growth, against a $5.20 prior-year base, an acceleration from roughly 4% in the third quarter. The central tension is that Acuity is increasingly two businesses moving at different speeds. Acuity Intelligent Spaces (AIS) is accelerating and expanding margins. Acuity Brands Lighting (ABL), the core lighting segment that still produced about 77% of sales, is flat-to-down and losing adjusted margin.
The quality of the quarter deserves scrutiny, mostly because of GAAP noise. GAAP diluted EPS jumped 56% to $5.63. That figure was flattered by $44.9 million in tariff refunds and by the absence of the prior year's $30.9 million pension settlement loss, partly offset by $17.8 million of special charges. Management excluded the tariff refunds from adjusted results, so the $5.77 adjusted figure is the cleaner read. On that basis, adjusted operating profit rose only 3.4% and adjusted operating margin improved just 10 basis points to 18.7%. Below the operating line, lower interest expense and a lower diluted share count, about 30.8 million shares versus 31.5 million, did meaningful work. The share count fell because Acuity repurchased $287 million of stock during the year.
The segments tell the real story. AIS sales rose 16.6% to $297.6 million, up from 15% growth in the third quarter. Adjusted operating margin reached 24.9%, a 350-basis-point year-over-year gain, compared with 150 basis points of expansion the prior quarter. Adjusted gross margin of 61.2% topped the 60% level management had previously called comfortable. ABL sales slipped 0.4% to $958.7 million, and adjusted operating margin fell 130 basis points to 18.8%. That decline was steeper than the 60-basis-point drop in the third quarter, as selling and administrative costs rose about 200 basis points of sales on technology investment. There was one genuine bright spot. ABL's independent sales network grew 3.8% after two flat quarters, and management cited share gains. Management's description of lighting demand has progressed steadily, from "tepid" early in the year to "continued firming" now. The direct sales network, however, fell 24.2%, and ABL's two-year stacked growth was flat versus +1% in the third quarter.
Initial fiscal 2027 guidance of $4.7 billion to $4.9 billion in sales and $20.50 to $22.00 in adjusted EPS implies modest growth from fiscal 2026's $19.90. The guide is credible but unspectacular, and the underlying assumptions show why. Management expects ABL to be flat to up low single digits while assuming the lighting market is flat to down, so the segment must rely on share gains. AIS is guided to low-to-mid-teens growth. However, memory cost inflation is now quantified at roughly 200 basis points of AIS gross margin pressure starting late in the fiscal first quarter. As a result, AIS operating margin is guided only flat to slightly up, which pauses the expansion story that drove this quarter. ABL also faces commodity, steel and freight inflation, though a normal price increase takes effect in December.
There are offsetting catalysts:
- a purpose-built data center luminaire and Distech controllers positioned with multiple hyperscalers;
- Ruth Gratzky, a former Siemens executive, named president of ABL;
- footprint consolidation and product rationalization aimed at ABL gross margin.
Cash generation was the cleanest positive. Operating cash flow rose to $826 million and free cash flow to $748 million, helped by the tariff refunds. The term loan used to fund the QSC acquisition was fully repaid after quarter-end, which frees capacity for an active AIS acquisition pipeline and further buybacks.
The market had been skeptical heading in. Shares fell 11.5% from the open after the June report to $309.81. That left them 1.7% below the 200-day moving average and just 4.8% above the inter-earnings low of $295.76 set September 17. They were 18.2% below the $378.65 high reached shortly after the last report, meaning the stock gave back its entire post-June rally. Investor sentiment remained positive but weakened materially, falling from 0.24 to 0.07. The AVWAP trend reading is negative, consistent with buyers who have been underwater since summer.
The bottom line is that Acuity delivered a respectable quarter whose strength sits almost entirely in Intelligent Spaces. The whisper miss is marginal, but the guidance does not offer the margin-expansion story that a de-rated stock might need to re-engage buyers. AIS margins are set to stall on memory costs, and ABL is still trading profitability for technology investment in a flat market. Bulls can point to firming lighting orders, data center traction, and a debt-free path to deploying capital. Bears have legitimate ammunition in decelerating ABL trends and a fiscal 2027 outlook that leans on share gains rather than market recovery.
