Cintas Q1 FY2027: 51.5% Gross Margin on $3.01B, With UniFirst Pending

Cintas rents uniforms, floor mats and shop towels, and it kept more than half of every revenue dollar as gross margin last quarter. Revenue for the three months ended August 31, 2026 rose 10.9% to $3.01 billion. The cost of delivering it rose 8.1%. Gross margin reached 51.5%, which the company calls a record, operating income rose 15.2% to $711.9 million, and net income rose 12.3% to $551.7 million. In fiscal 2022 the same margin was 46.2%. Nothing dramatic happened in between. It moved up about a point a year, every year, and five years of filings show which lines moved it.

The Headline Numbers​

Start with the two cost lines. Revenue grew 10.9% and the combined cost of sales grew 8.1%. That gap is the whole quarter. Gross margin dollars rose $187.0 million on $295.9 million of added revenue, so 63 cents of each new revenue dollar reached gross margin, against a 50.3% rate on the existing book a year ago.

Selling and administrative expenses grew 10.5%, almost exactly in line with revenue. They were 27.4% of revenue this quarter and 27.5% a year ago. So the margin gain was earned in the plants and on the routes, and overhead neither helped nor hurt.

Two lines below operating income explain why net income grew more slowly than operating income. The effective tax rate was 20.0% against 17.6% a year ago. The release says both rates "were impacted by certain discrete items, primarily the tax accounting impact for stock-based compensation." And operating income carries $14.4 million of transaction expenses for the pending UniFirst acquisition. Without that line, operating income would have been $726.3 million, or 24.1% of revenue. The release reports adjusted diluted EPS of $1.39 on the same basis.

One note on the calendar. The quarter had 66 workdays against 65 a year ago. The release adjusts for that and for acquisitions and currency to reach organic growth of 8.9%. Organic growth in the four quarters of fiscal 2026 was 7.8%, 8.6%, 8.2% and 8.4%, so this is the fastest of the last five.

Revenue Deep Dive​

Uniform Rental and Facility Services is 76% of revenue and the reason the company exists. A truck runs a fixed route each week, drops clean garments, mats, mops and towels, and picks up the dirty ones. Revenue rose 9.7% and segment gross margin rose from 49.7% to 50.8%. Operating income rose 15.0% to $575.1 million. The fiscal 2026 10-K, filed in July, gives the mechanism for the same trend over the full year: the improvement was "primarily due to more efficient use of in-service inventory and production efficiency gains." The quarter's release does not break the gain down further.

First Aid and Safety Services grew fastest at 16.1% and has the highest gross margin at 57.6%. It stocks first aid cabinets, safety supplies and water coolers on the same kind of recurring route. Segment operating income rose 23.9% to $99.5 million. At a 25.6% operating margin it is now slightly more profitable per dollar than the rental business. Two years ago, in fiscal 2024, its full-year operating margin was 22.4%.

All Other is fire protection services and direct uniform sales. Revenue rose 13.1% and operating income rose 37.4% to $51.7 million, as gross margin moved from 47.2% to 49.5%. It remains the lowest-margin group at 15.6%.

The income statement itself uses a coarser split: uniform rental and facility services revenue of $2,294.7 million and "other" revenue of $719.2 million, which is First Aid plus All Other. The ledger keeps one revenue posting and records that split in its comment.

We read the release for the seven demand and supply themes we track in every earnings post. We did not read a call transcript, and nothing here is quoted from one. What the release says:

• Demand. The chief executive's statement describes "another strong quarter, producing record revenue and record operating margin." That is a statement about results. The release contains no sentence about customer demand, order intake or bookings. The 8.9% organic growth rate is the only demand evidence, and it is a number.
• Selling prices. The quarter's release does not mention pricing at all. The fiscal 2026 10-K names price increases in every business without sizing them. Rental revenue growth "was a result of new business, the penetration of additional products and services into existing customers and price increases, partially offset by lost business." Other revenue "improved from increases in sales representative productivity and price increases." For the company as a whole, the same filing says revenue grew organically "primarily as a result of increased sales volume."
• Market expansion. The only expansion language concerns the acquisition: "the substantial value we expect to create for shareholders and customers through the transaction."
• Guidance. Management raised it. Fiscal 2027 revenue is now expected between $12.15 billion and $12.27 billion, up from $12.10 billion to $12.25 billion, and adjusted diluted EPS between $5.45 and $5.54, up from $5.36 to $5.50.

Four themes are absent: demand exceeding supply, tight supply, an industry upcycle, and a product ramp. For a route business that is the expected finding. Cintas does not sell out. It adds stops. The claim to test is "ongoing investments in technology, capacity and talent", and the test is whether capital spending and overhead are rising faster than revenue. Neither is: capital expenditures were $107.5 million in the quarter against $102.0 million a year ago, up 5.5% on revenue up 10.9%.

The Margin Story​

Read the gross margin column top to bottom: 46.2%, 47.3%, 48.8%, 50.0%, 50.7%, and 51.5% in the latest quarter. That is 5.3 points in a little over four years with no step back.

Now read the next column. Selling and administrative expenses went the other way, from 26.0% of revenue to 27.4%. Cintas has spent more on selling and administration per revenue dollar, and the release's phrase about investments in "technology, capacity and talent" is where that shows. So operating margin rose 3.4 points across the same period in which gross margin rose 5.3. About a third of the plant-level gain was reinvested in overhead.

This matters for how to read "record operating margin". All of the gain came from cost of sales. The filings name the sources over the years: energy efficiency, routing, and above all how long a garment or mat stays in service before it is replaced. That last one is an accounting line as much as an operating one, and it is the reason the ledger gives it its own account, which we come to below.

On price versus volume, the filings give less than an analyst would like. Cintas does not disclose a price index or a unit count. The 10-K lists price increases among the growth drivers in each business, says total organic growth came "primarily as a result of increased sales volume", and attributes the gross margin gain to efficiency. A reader should not credit the margin to pricing on this evidence.

The One Big Question: What Does UniFirst Do to This Balance Sheet?​

On March 10, 2026, Cintas agreed to acquire UniFirst Corporation, which the 10-K describes as a North American supplier of uniform and workwear programs, facility service products and first aid and safety supplies. The filing values the transaction at approximately $5.5 billion. Each UniFirst share converts into $155.00 in cash and 0.7720 Cintas shares. UniFirst's shareholders approved the deal on June 12, 2026. It has not closed. The release says: "We continue to engage with the U.S. Federal Trade Commission as it reviews our transaction with UniFirst", and that completion is expected "prior to the end of calendar 2026." The July 10-K said "the second half of calendar 2026."

None of UniFirst is in these numbers. The guidance excludes it too. What is in the numbers is the cost of waiting and the shape of the balance sheet that has to absorb it.

Three facts stand out. First, a $5.5 billion purchase is more than half of Cintas's own total assets of $10.65 billion. Cintas has made many small acquisitions, between $46 million and $233 million of cash a year across fiscal 2022 through fiscal 2026. This one is a different order of size.

Second, Cintas runs with little cash: $243.6 million at quarter end. It is not a company that stockpiles. The cash portion of the deal will be borrowed. The 10-K describes the financing: a committed 364-day bridge facility of $2.85 billion in two tranches, one of which was replaced by $1.25 billion of commitments under a new $2.0 billion revolving credit facility that runs to March 2031. Nothing was drawn on either at May 31, 2026.

Third, $1.0 billion of 3.70% senior notes mature in fiscal 2027. They moved into "debt due within one year" at May 31, 2026, which is why current liabilities jumped from $1.64 billion to $2.69 billion in one year while total debt stayed at $2.43 billion. That refinancing arrives in the same year as the acquisition funding.

The cost of waiting is visible but small. Transaction expenses were $15.1 million in fiscal 2026 and $14.4 million in this quarter alone. The company also guides to fiscal 2027 net interest of about $103.0 million against $101.2 million, "primarily a result of the amortization of bridge loan financing expenses." And the guidance footnote says the adjusted EPS range excludes transaction costs "which cannot be reasonably estimated at this time."

Against that, the capacity to carry debt is real. Operating cash flow was $572.3 million in the quarter and $2.28 billion in fiscal 2026. Interest expense was $24.7 million against operating income of $711.9 million. A company that covers its interest about 29 times over can borrow. The question the filings cannot answer yet is what regulators require, and whether the deal closes on the terms signed.

Tracking an $11B Route Business in Plain Text​

A rental company's central asset is easy to miss in a summary: the garments and mats already sitting at customers. Double-entry bookkeeping puts that asset on its own line and forces its cost through the income statement on a schedule. The conventions are the ones we use for every company in this series: how we model every company. Income postings are credits (negative), expenses are debits (positive), and Equity:Adjustments takes net income so the transaction sums to zero while the balance assertions pin retained earnings. Cintas files in thousands, so the ledger keeps three decimals of MUSD and every figure equals the filed one.

; Check: −3,013.981 + 1,128.884 + 331.554 + 827.244 + 14.412 + 24.706 + −2.649 + 138.119 + 551.711 = 0 ✓
2026-08-31 * "Cintas Corporation" "FY2027Q1 Income Statement"
  Income:Revenue                              -3013.981 MUSD  ; total revenue: uniform rental and facility services 2,294,736 + other 719,245

  Expenses:SellingGeneralAdministrative          14.412 MUSD  ; UniFirst Corporation transaction expenses — the filing's own separate operating line (named one-off)

  Equity:Adjustments                            551.711 MUSD  ; net income offset (RE set by balance assertion)

Three things are worth noticing. Expenses:CostOfRevenue appears twice because the filing prints two cost lines and no total; the ledger keeps both as filed. The UniFirst expense is a second, labeled posting on the selling and administrative account, so the one-off can be seen and subtracted without being hidden. And revenue is a single posting whose comment carries the rental and other split.

The balance-sheet line that tells this company's story is one most ledgers do not have:

2022-05-31 balance Assets:Current:UniformsAndRentalItemsInService        916.706 MUSD  ; uniforms and other rental items in service
2026-05-31 balance Assets:Current:UniformsAndRentalItemsInService       1276.174 MUSD  ; uniforms and other rental items in service
2026-08-31 balance Assets:Current:UniformsAndRentalItemsInService       1309.995 MUSD  ; uniforms and other rental items in service

Cintas carries $1.31 billion of uniforms and rental items in service, kept apart from the $433.3 million of inventory still on the shelf. The 10-K explains the accounting: these items are "valued at cost less amortization, calculated using the straight-line method", uniforms over 18 to 30 months and other rental items over 8 to 60 months. The amortization lands in cost of uniform rental and facility services. So when a garment lasts longer in use, less cost flows through that line. That is the "more efficient use of in-service inventory" the 10-K credits for the margin, and it is why this asset growing 39% from fiscal 2022 to fiscal 2026 while rental revenue grew 38% is a healthy sign: the stock of garments has kept pace with the revenue it supports, and no more.

Retained earnings give a second check. The balance moved from $13,074.0 million to $13,416.9 million in the quarter, an increase of $342.9 million. Net income was $551.7 million. The $208.8 million difference is the quarterly dividend, which the release says was paid on September 15, 2026. The ledger never records the dividend as a transaction. It falls out of two balance assertions and one income statement.

The Multi-Year Arc​

Revenue grew 43.4% from fiscal 2022 to fiscal 2026, or 9.4% a year. Net income grew 61.8%, or 12.8% a year. The gap between those two growth rates is the margin story in one line.

The route count explains part of it. Cintas reported approximately 11,300 local delivery routes at May 31, 2022 and approximately 12,500 at May 31, 2026. Routes grew about 11% while revenue grew 43%. By our arithmetic, revenue per route went from roughly $695,000 to roughly $901,000. A truck that already stops at a customer for uniforms can also drop first aid supplies and restroom products, and the fixed cost of the route is spread across more revenue. That is the compounding mechanism, and it does not depend on any one year.

The right-hand columns show where the money went. Over the five fiscal years Cintas earned $7.97 billion and returned $7.18 billion to shareholders: $2.67 billion in dividends and $4.51 billion in repurchases. That is 90% of net income. Treasury stock at cost is now $11.24 billion, more than the company's total assets. Shareholders' equity of $5.2 billion is what remains after buying back more than twice that amount.

This is also why the UniFirst deal is a change of habit. For five years the answer to "what does Cintas do with its cash" was "hand it back." A $5.5 billion acquisition funded partly with new shares and partly with debt is the first time in this ledger that capital goes the other way at scale.

For another route-like, recurring-revenue business with a May fiscal year and a large acquisition to digest, compare the Paychex ledger.

The Verdict: Bull vs. Bear​

Bull Case

• Gross margin has risen in every period in the ledger, from 46.2% in fiscal 2022 to 51.5% this quarter, and the filings attribute it to efficiency in the plants and in-service inventory, which does not reverse when a price increase lapses.
• Organic growth of 8.9% is the fastest of the last five quarters, and management raised both ends of its revenue and adjusted EPS guidance.
• All three business groups expanded gross margin and grew operating income faster than revenue: 15.0%, 23.9% and 37.4%.
• Operating cash flow was $572.3 million in the quarter, up 38.1%, against capital expenditures of $107.5 million.
• Interest expense of $24.7 million is covered about 29 times by operating income, which leaves room to finance an acquisition.

Bear Case

• The release makes no claim about demand, pricing or supply. "Record revenue and record operating margin" describes the result. A reader looking for forward evidence gets only the guidance range.
• Selling and administrative expenses have risen from 26.0% to 27.4% of revenue since fiscal 2022. The operating leverage is entirely in cost of sales, and gross margin cannot rise a point a year indefinitely.
• The UniFirst acquisition is still under Federal Trade Commission review more than six months after signing. Management expects closing "prior to the end of calendar 2026", the filings name no date, and transaction costs were $14.4 million this quarter.
• $1.0 billion of senior notes come due in fiscal 2027 against $243.6 million of cash, in the same year the deal's cash consideration must be funded.
• The effective tax rate rose from 17.6% to 20.0%, and the company guides to 20.4% for the year, so net income will keep growing more slowly than operating income.
• Guidance excludes UniFirst entirely. The numbers investors are given for fiscal 2027 describe a company that management expects to stop existing in that form before the year ends.

Our Take. This is a business that improves a little every year, and the quarter shows it still does. We think the margin record is real and well explained: it sits in cost of sales, the filings say why, and the in-service asset on the balance sheet is consistent with the explanation. What the quarter cannot tell you is the thing that matters most for the next two years. Cintas has spent five years returning 90% of its earnings and making small acquisitions. It is now waiting on a regulator to approve one worth more than half its balance sheet. The base business gives it the cash flow to carry that. The line to watch is Expenses:CostOfRevenue as a share of revenue once UniFirst's plants and routes are in it. If the combined company can bring those to Cintas's 50.8% rental gross margin, the deal works. The first combined quarter will show the starting point.
