Cintas Posts Record $3 B Q1 Revenue, Raises FY2027 Outlook Amid Mixed Stock Reaction

CTAS reported fiscal 2027 first-quarter revenue of $3.01 billion on September 23, up 10.9% from $2.72 billion a year earlier and a quarterly record. That topped the $2.98 billion consensus, and diluted EPS of $1.36 edged past the $1.35 estimate. Adjusted EPS was $1.39, up 15.8%, and gross margin widened to 51.5% from 50.3%, with operating margin at 23.6% versus 22.7% a year ago.

Cintas raised its outlook on both lines. Full-year revenue guidance moved to $12.15 billion to $12.27 billion from $12.10 billion to $12.25 billion, and adjusted EPS guidance rose to $5.45 to $5.54 from $5.36 to $5.50. The quarter carried $14.4 million of transaction expenses tied to the proposed UniFirst acquisition, which reduced diluted EPS by $0.03.

The stock reaction was muted despite the beat-and-raise: shares fell 1.2% in premarket trading. The concrete reason in the coverage is that the new revenue guidance midpoint of $12.21 billion sits slightly below the $12.22 billion full-year consensus. Longer-running valuation debate adds to the caution: Simply Wall St notes the stock has slipped about 10% over the past year and trades at a 41.3x P/E, which leaves little room for margin gains to slow.

What to watch: whether Cintas keeps raising guidance through the year, the progress and cost of the UniFirst deal, and whether margin expansion holds as the company integrates it.
