What happened
Acuity Inc. (NYSE: AYI)'s smaller Intelligent Spaces business supplied the growth its lighting segment did not.
Fourth-quarter company sales rose 2.9% to $1.24 billion. Adjusted operating profit increased 3.4% to $232.9 million, and adjusted operating margin edged up 10 basis points to 18.7%.

Why it matters
Intelligent Spaces added $42.4 million of sales from a year earlier. That increase was $7.1 million larger than the entire company's $35.3 million increase. Lower Lighting sales and other consolidation effects offset part of the segment's growth.
The mix also moved toward Intelligent Spaces. Its sales equaled 23.9% of consolidated sales, up from 21.1% a year earlier. More important, the segment's adjusted margin moved above Lighting's margin rather than buying growth at weaker profitability.
That changes the assumption that Acuity Inc. (NYSE: AYI)'s newer portfolio is only a small acquisition-led add-on. It is now the clearer source of sales growth and adjusted margin expansion in the quarter.
The countercase is scale. Lighting still generated about 77% of consolidated sales, so a prolonged decline there can outweigh progress elsewhere. Acuity Inc. (NYSE: AYI) also did not separate organic growth from acquisition or portfolio effects for Intelligent Spaces in the release.
Reported profit benefited from $44.9 million of tariff refunds, but management excluded that item from adjusted results. The segment comparison above therefore uses adjusted operating margins rather than the larger GAAP profit increase.

What's next
Watch whether Intelligent Spaces keeps double-digit sales growth and a margin advantage as prior acquisitions become fully comparable. Named customer wins, recurring software revenue and cash conversion would make the shift more durable.
Lighting must also stabilize. If that segment returns to growth while holding margins, Acuity Inc. (NYSE: AYI) could have two operating engines. Another Lighting decline with slower Intelligent Spaces growth would show that one segment is still carrying the company.
