Acuity

Acuity's sales grew 3% year on year to $1.2 billion in its fiscal fourth quarter, while adjusted operating profit rose 10 basis points to 18.7%. While sales were in line with expectations and the margin surprised a smidge to the upside, the stock declined by 3% on the trading day.

Why it matters: 2027 sales guidance was a touch light, but our outlook for adjusted EBITDA remains roughly the same. Our thesis continues to hang on the success of the intelligent spaces segment, though fears of a slowdown in lighting from higher interest rates are likely hurting sentiment. Lighting is Acuity's core business and roughly three-fourths of its sales mix, so softer sales guidance coupled with fears of a commercial slowdown are going to disproportionately affect Acuity's stock price. Still, we think these are transient, and the outlook benefits from self-help initiatives. Even with the slowdown in lighting, the outlook for intelligent spaces' top line continues to improve, particularly given the innovative offerings focused on both interoperable and autonomous systems. Order strength in this business should drive the rerating we're watching for.

The bottom line: We lift our fair value estimate for narrow-moat-rated Acuity to $388 from $380, solely due to the time value of money. We also raise our Morningstar Uncertainty Rating to High from Medium to reflect greater macroeconomic headwinds and memory cost inflation in intelligent spaces. The stock trades in 4-star territory, with nearly 30% upside. We think the market fails to appreciate how initiatives like pricing and productivity should help offset inflationary impacts, while lighting initiatives to enter new verticals should help offset cyclical sales headwinds. Acuity's positioning itself to win in the rapidly growing hyperscaler market. Strong brands position it well, and if it achieves success, we think it'd be hard to disintermediate it given how many functions are integrated into Acuity's automation controls.

Following fourth-quarter results, we lift our fair value estimate for narrow-moat rated Acuity to $388 from $380 solely due to time value of money. While 2027 sales guidance was a touch light our outlook for adjusted EBITDA remains roughly the same, and our long-term outlook remains unchanged.

We model mid-single-digit consolidated organic revenue growth during our five-year forecast. We expect lighting segment revenue to grow between a 2% and 3% compound annual rate, driven by market growth, market share gains, and entry into new verticals.

Our forecast assumes higher growth for the intelligent spaces segment. On an organic basis, we forecast segment revenue will grow at a low-double-digit compound annual rate, driven by market growth and market share gains. While we expect lighting to continue to contribute the bulk of revenue, we expect an increasing contribution from intelligent spaces. We expect the AIS segment to constitute over 29% of revenue in fiscal 2028, up from 18% in fiscal 2024.

We expect continued margin improvement. For lighting, we forecast roughly 45 basis points of segment operating margin improvements per year as the company continues to optimize its offerings and pricing strategy. As a result, we forecast segment adjusted operating margins to nearly 21% in fiscal 2029. For intelligent spaces, we forecast segment adjusted operating profit expanding to roughly 25% in fiscal 2029 from less than 22% in fiscal 2024. We see operating leverage as the primary driver of margin growth.

We award Acuity a narrow economic moat rating, based primarily on intangible assets in the Acuity Brands Lighting segment. Acuity has consistently earned returns on invested capital above its cost of capital, and we expect this to continue for at least the next decade.

The ABL segment consists of lighting and lighting controls offerings. ABL is the largest lighting business in North America, with an estimated market share of 25%, roughly equivalent to the second- and third-largest competitors combined. We believe ABL has carved out a moaty niche in North American professional lighting. We view this as the most attractive lighting market globally, given its unique industry structure relative to other lighting markets.

ABL products are sold through five channels: independent sales networks, direct sales networks, retail, corporate, and original equipment manufacturers/other. ISNs are most of the segment’s sales, consistently contributing about 70% of ABL's revenue. ISNs generally service the new-build and retrofit commercial and industrial segment, a large addressable market. The independent sales network is unique relative to other electrical equipment and other lighting markets, which lack a similar structure. We believe the unique sales structure of North American professional lighting creates barriers to entry for new entrants and is a key point in understanding Acuity’s moat.

We think the structure is unique and key to Acuity’s moat because an ISN’s manufacturer-agent relationship is symbiotic, with the agent needing a strong manufacturer and the manufacturer needing a competent agent. This symbiotic relationship underpins our moat rating because Acuity is affiliated with the top-selling agent in a majority of North America’s roughly 60 lighting markets. Further, ISNs are typically affiliated with a particular brand. For example, in a given market, there will typically be an Acuity agent, a Cooper Lighting agent, and a Current (GE, Hubbell) agent, among others. Acuity’s relationship with many of the top-selling agencies in North America is a key to its success.

We think Acuity has developed strong relationships with top-selling agents due to its product breadth, vitality, and value. In the North American professional lighting market, we believe Acuity has among the greatest product breadth. It offers products across the quality range of good, better, and best. Historically, the majority of its sales have been made to order, further limiting new entrants that may lack the scale and market expertise of Acuity. For Acuity’s more standard products, it has materially increased its product vitality in recent years. Historically, roughly 10% of its products were refreshed each year. This is now 25% and ensures the company has the right product fit for the range of end-market applications. While Acuity has industry-leading product breadth and product vitality, it aims to sell at reasonable prices. We view its pricing strategy to be in line with peers, not at a material premium or discount.

Moreover, agents that sell Acuity luminaires (light fixtures, not the bulbs themselves) are not allowed to sell other companies’ lighting controls. This relationship drives an element of switching costs within the segment by requiring agents that want access to Acuity’s product breadth of luminaires to also sell its lighting controls. While we do not have an exact estimate of the revenue breakdown between luminaires and lighting controls, we believe lighting controls' contribution is nontrivial and continues to grow.

Beyond the ISNs, the ABL segment's sales consist of a direct sales network, corporate accounts, and retail sales. We believe the direct sales network and corporate accounts lend themselves to more moat dynamics than retail sales. The direct sales network consists of infrastructure projects (street and bridge lighting, for example) that carry high costs of failure, keeping lower-priced competition largely out of this market. On the other hand, corporate accounts address large brick-and-mortar chains that have a repeatable relationship with a particular lighting manufacturer. In contrast, we see the retail (residential) as the least moaty of the ABL sales. First, residential customers have little brand affinity in lighting. Also, this channel has by far the highest prevalence of low-cost imported products.

Acuity’s AIS segment houses intelligent building solutions. Traditionally, this segment has focused on building management systems, which allow for centralized control of building HVAC settings, lighting, fire, and other specifications for spaces like office buildings. Broadly, we view the building automation industry as lending itself to switching costs. Once installed within a building’s infrastructure, BMS solutions are cumbersome to switch, leading customers to stick with the initial solution for long periods of time. Furthermore, some BMS offerings only work with the same brand of equipment, forming a closed ecosystem that would be incompatible with other brands. However, Acuity is a newer entrant to the industry and lacks the scale and installed base of larger competitors like Honeywell or Johnson Controls.

In 2025, Acuity expanded its product offering in this segment to include intelligent audio and visual solutions via its acquisition of QSC. We see this acquisition as potentially enhancing Acuity’s position in the market by providing a one-stop shop of BMS and audio/visual controls. However, we await further traction in marrying the two product offerings before awarding a switching costs moat source.

Acuity is the largest lighting company focused on the North American professional market, with a share of approximately 25%.

The AIS segment offers higher margins and a capital-light business model, potentially increasing long-term returns on invested capital.

Acuity has the opportunity to expand margins in its ABL segment as it optimizes its product portfolio.

Acuity’s ABL segment is subject to competition from low-cost imports in portions of its portfolio.

Acuity’s investments in scaling its AIS segment via organic and inorganic growth could fail to pay off.

The lighting industry is sensitive to nonresidential construction spending, which is cyclical and subject to general economic activity.
