Acuity Inc. (AYI) FY2026 10-K: Intelligent Spaces Surge 45%, Driving 50.6% Gross Margin

When you walk into a modern office building, hospital, or airport, the lighting above you and the climate controls on the wall are increasingly part of an interconnected digital ecosystem. At the center of this industrial technology space is Acuity Inc. (NYSE: AYI)—formerly known as Acuity Brands—a leading provider of commercial lighting solutions and intelligent building management systems. Today, our goal is to dig into the income statement from the company’s latest 10-K filing for the fiscal year ended August 31, 2026, to see how the business is performing and what we can learn from its shifting revenue mix.

Expanding Margins Through Higher-Tech Offerings

For fiscal 2026, Acuity generated $4.64 billion in total net sales, a solid 6.8% increase over the $4.35 billion recorded in fiscal 2025. Even more impressive is what happened further down the income statement: while revenue grew nearly 7%, the cost of products sold ticked up by just 1.1% to $2.29 billion.

This dynamic pushed Acuity’s gross profit (revenue minus the direct costs of manufacturing products) up 13.1% to $2.35 billion, expanding its gross margin by 280 basis points (2.8 percentage points) to 50.6%.

After accounting for $1.61 billion in selling, distribution, and administrative expenses and $23.7 million in special charges (primarily severance and asset impairments), operating profit jumped 26.6% to $713.7 million, representing a healthy 15.4% operating margin. On the bottom line, net income rose 34.0% to $531.3 million, or $17.05 per diluted share (up from $12.53 in fiscal 2025), aided in part by the absence of a $30.9 million pension settlement loss that weighed on the prior year's miscellaneous expenses.

The following flow diagram illustrates how Acuity’s fiscal 2026 revenues flowed through its cost structure to reach net income:

Intelligent Spaces Steals the Spotlight

A closer look at Acuity’s two operating segments reveals the engine behind this margin expansion:

• Acuity Brands Lighting (ABL): This legacy segment produces commercial, architectural, and specialty LED luminaires and lighting controls sold primarily through independent sales networks ($2.70 billion) and direct channels ($314.2 million). In fiscal 2026, ABL’s revenue dipped 1.0% to $3.58 billion. However, disciplined cost management allowed ABL to expand its segment operating profit by 5.6% to $623.5 million (a 17.4% margin).
• Acuity Intelligent Spaces (AIS): This high-growth division focuses on building management software, HVAC controls, and cloud-manageable audio, video, and control platforms (bolstered by the January 2025 acquisition of QSC, LLC and its Q-SYS platform). AIS revenue surged 44.8% to $1.11 billion in fiscal 2026, crossing the billion-dollar threshold and growing from 17.6% of total company sales in 2025 to nearly 24% in 2026. Because software and smart-space controls carry much higher gross margins (61.3% for AIS vs. 46.8% for ABL), AIS’s operating profit more than doubled, soaring 145.1% to $186.5 million.

Cash Flow and Balance Sheet Discipline

Acuity’s strong earnings translated directly into cash generation. Operating cash flow jumped 37.3% to $825.6 million, helped by a $74.7 million reduction in inventory levels. Management deployed this cash aggressively to strengthen the balance sheet and reward shareholders:

• Deleveraging: After borrowing $600 million in fiscal 2025 to help fund the $1.24 billion QSC acquisition, Acuity paid down $400 million of its term loan during fiscal 2026 (while drawing $200 million on its credit agreement), and subsequently paid off the remaining $200 million credit agreement balance in September 2026.
• Shareholder Returns: The company repurchased roughly 900,000 shares for $289.5 million and paid $23.8 million in dividends ($0.77 per share).

Looking Ahead

Acuity’s fiscal 2026 results highlight a successful strategic pivot. While its core lighting business faces mature market conditions and intense competition from global heavyweights like Signify (Philips) and Hubbell—alongside ongoing supply chain sensitivities, tariff complexities, and interest-rate pressures on commercial construction—the rapid scaling of Acuity Intelligent Spaces is fundamentally reshaping the company's profitability profile. With AIS now generating nearly a quarter of total revenue at a 61%+ gross margin and acquisition debt rapidly being retired, Acuity enters fiscal 2027 on a remarkably solid financial footing.
