CTAS vs FA: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: FA is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CTAS and FA share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CTAS and FA exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

Cintas Corporation rents and services the unglamorous essentials that keep businesses running: work uniforms, floor mats, mops, restroom and hygiene supplies, first aid cabinets, safety training, and fire protection. Its core Uniform Rental and Facility Services segment is a route-based subscription model, where the same trucks visit hundreds of thousands of customer locations on a recurring schedule, which produces sticky, repeatable revenue. A smaller First Aid and Safety Services segment and a Fire Protection business round out the mix. Cintas is a component of the S&P 500 and the leading player in its category, with an estimated one-third share of a still-fragmented North American uniform rental market.

First Advantage Corporation provides background checks, identity verification, drug and health screening, and compliance solutions used by employers to vet and onboard workers. The company serves roughly 80,000 organizations globally and processes hundreds of millions of screens a year, positioning itself as infrastructure for hiring. Its early-2025 acquisition of Sterling Check for about $2.2 billion combined the two largest independent screeners and roughly doubled First Advantage's revenue, adding scale, cross-sell opportunities, and cost synergies.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CTAS drivers: Route density and cross-selling; Penetrating a fragmented market.
• FA drivers: Sterling integration and synergies; Recurring, embedded demand.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant risk is valuation: at roughly 35 times trailing earnings, the stock prices in years of continued execution, so any growth stumble could compress the multiple sharply. For FA, revenue is directly tied to hiring volumes, so a weakening labor market or slower base growth pressures results.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CTAS if you believe its drivers more; FA if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CTAS and FA guides.

CTAS. Cintas reported fiscal 2026 third-quarter revenue of about $2.84 billion, up roughly 8.9 percent year over year, with diluted earnings per share of about $1.24 and a record gross margin near 51 percent. Management raised full-year guidance toward $11.2 billion in revenue. The trailing price-to-earnings ratio in the mid-30s sits well above the commercial-services industry average, reflecting the market's premium for the company's consistency.

FA. First Advantage trades as a leveraged, scaled leader rather than a high-multiple growth name, with much of the equity story resting on debt reduction and synergy capture. FY2025 revenue jumped about 83 percent year over year, but that reflects the Sterling acquisition rather than organic growth, which runs in the mid-single digits. Adjusted EPS guidance of roughly $1.15 to $1.25 for 2026 frames the earnings base against the balance sheet.

Headline figures (approximate, JUNE 2026): CTAS shows revenue (ttm) ~$11.0B, fy2026 revenue guidance ~$11.21B to $11.24B, q3 fy2026 revenue ~$2.84B (up ~8.9%), net income (ttm) ~$1.9B; FA shows revenue (fy2025) ~$1.57B, q1 2026 revenue ~$385M (up ~8.6% YoY), 2026 revenue guidance ~$1.625B to $1.7B, 2026 adj. ebitda guidance ~$460M to $485M.

CTAS and FA are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
