Carlisle Companies (CSL) Q3 2026 earnings review
Carlisle sales grow 9%, but higher material costs squeeze margins
Carlisle Companies, a maker of commercial roofing and building insulation, grew sales briskly while higher chemical and freight bills squeezed its profit margins. Sales rose 9% to $1.5 billion with no let-up after customers bought early last quarter, but operating profit stood still because price increases lagged oil-linked material costs. Net profit fell, yet per-share profit excluding one-offs rose 6% because buybacks shrank the share count.
| Sales from businesses owned a year ago | +8.8% up from +7.9% last quarter |
|---|---|
| Adjusted EBITDA margin | 23.8% -2.1 percentage points from a year ago |
| Profit per share, excluding one-offs | $5.92 +6% from a year ago on 8% fewer shares |
| Fourth-quarter margin outlook | Flat YoY implies full-year margin falls 0.6 points by our math |
⚖️ Verdict: 🔴 Bearish
The story got worse because the second-half margin recovery management promised in July has slipped into next year. Chief executive Chris Koch blamed the Middle East conflict for pushing material and freight costs above the July plan, and by our math the fourth-quarter outlook leaves full-year adjusted EBITDA margin down 0.6 percentage points instead of flat. One bright spot: both divisions kept growing volume and taking market share even as they raised prices.
The question now is whether Carlisle's price increases will catch up with chemical costs in early 2027 or merely keep pace with inflation. If raw material costs level off, delayed price increases will lift margins next year; if construction stays weak or oil keeps rising, per-share profit growth will keep leaning on debt-funded buybacks. Fourth-quarter segment margins in February will show whether the gap is closing.
🐂 Bull Case
Roofing Sales Accelerated After Pre-Buying
Carlisle makes commercial roofing and building insulation, and last quarter a couple of percentage points of its growth came from customers buying early before price increases. That raised the risk of a third-quarter air pocket, especially with commercial and residential new construction still weak. Instead, sales from businesses owned a year ago rose 8.8%, faster than the 7.9% pace in the second quarter.
Carlisle Construction Materials (CCM, the commercial roofing unit) grew underlying sales 8.5%, which chief executive Chris Koch attributed to "strong volume from our strategic initiatives, including growing traction in data centers, together with solid re-roofing demand and price realization". Carlisle Weatherproofing Technologies (CWT, which makes building insulation and waterproofing) grew underlying sales 9.6% on market share gains and "weather conditions that drove demand for roof coatings".
This matters because the company passed through three rounds of price increases and higher freight charges without losing order volume. Management also forecast high-single-digit sales growth in both divisions for the fourth quarter, showing that replacement roofing demand is overriding the new-construction slump.
What to watch: the split between volume and price in the third-quarter conference call remarks. If volume grew in both divisions after the second-quarter early buying, underlying demand is stronger than the building market.
Nine of Twelve New Products Reached the Market
A core part of Carlisle's strategy is launching energy-efficient building products that save contractors labor on the roof. By the end of the third quarter, the building-products maker had put nine of the twelve new products planned for 2026 into the market, up from about half the slate three months ago, while spending $11.9 million on research and development.
These launches, alongside growing sales into data centers and higher demand for roof coatings, helped both divisions grow faster than their end markets. What to watch: full-year revenue from new products at the fourth-quarter report. Rising contribution per square foot would show the new lineup is lifting prices and market share.
🐻 Bear Case
Chemical and Freight Costs Wiped Out Margin Plans
Carlisle has raised prices and freight surcharges since April, and bulls expected those increases to lift revenue and restore profit margins in the second half. "Renewed escalation of the conflict in the Middle East drove petroleum-derived raw material, diesel, and freight costs higher, well above what we anticipated in our July outlook," chief executive Chris Koch said. "We view this as a timing issue, not a structural one."
The numbers show the margin recovery has slipped out of 2026. Cost of goods sold — the cost of making and shipping the products — jumped 2.2 percentage points of revenue to 66.2%, pulling gross margin down to 33.8%.
- Adjusted EBITDA margin: 23.8%, down 2.1 percentage points from a year ago
- Commercial roofing (CCM) adjusted EBITDA margin: 28.2%, down 2.0 percentage points and below the roughly 29% July plan
- Fourth-quarter margin outlook: flat from a year ago at about 22.1%, implying 23.8% for the full year by our math
That implied 23.8% full-year margin falls 0.6 percentage points short of last year's 24.4%, breaking the company's July plan for a flat full-year margin. It is the second time this year management has lowered its margin sights after starting 2026 planning for a 0.5 percentage point expansion.
What to watch: fourth-quarter CCM adjusted EBITDA margin against last year's 26.8%. A reading below 26.8% would mean price increases still have not caught up with chemical and freight bills.
Weatherproofing Factory Savings Missed the Target
Carlisle has been consolidating factories and adding automation in its weatherproofing division (CWT), and bulls viewed the second quarter's margin improvement as the start of a structural turnaround. On the July call, management projected CWT's adjusted EBITDA margin would rise 2.5 percentage points from a year ago in the third quarter, to about 19.9%, as those savings took hold.
In the third quarter, CWT operating profit rose 31% to $38.9 million and adjusted EBITDA rose 13% to $68.3 million, helped by "investments in automation, manufacturing consolidation, and in-house expanded polystyrene resin capacity", Koch said. However, the segment's adjusted EBITDA margin reached only 18.0%, up 0.6 percentage points from a year ago and 1.9 percentage points below the July target because raw material and freight inflation ate up most of the savings.
What to watch: CWT's fourth-quarter adjusted EBITDA margin against the 15.9% it recorded a year ago. An increase smaller than 2.5 percentage points would confirm that chemical costs are absorbing the $20 million annual factory savings.
Buybacks Carry Earnings Growth as Cash Drops
Carlisle pitches itself as a capital-return story, and this quarter it raised its dividend 14% — its 50th straight annual increase — while buying back $350 million of stock to reach $850 million for the first nine months. Those buybacks cut the diluted share count by 7.7% from a year ago to 39.6 million, which turned a 2.6% drop in net profit excluding one-offs ($235.0 million vs $241.2 million) into a 5.5% rise in per-share profit to $5.92.
Funding that $990 million of nine-month shareholder returns against $406.9 million of free cash flow has drained cash from $1,112.1 million at year-end to $546.7 million. By our math, net debt rose 32% over the last nine months to $2,346.0 million while stockholders' equity fell 20% to $1,438.3 million, and quarterly interest expense jumped 30% from a year ago to $27.7 million.
What to watch: the 2027 share repurchase target and plans for the $600 million of senior notes due in 2027, given on the fourth-quarter call. A smaller buyback target would take away the main prop under per-share profit growth.
Long-Term Profit Goal Needs Faster Growth
Under its Vision 2030 plan, Carlisle aims to reach $40 of per-share profit excluding one-offs, and Koch said management "remain confident in our path to $40 of adjusted EPS". Through the first nine months of 2026, however, per-share profit excluding one-offs grew 7% to $16.55, and third-quarter operating profit was unchanged from a year ago at $293.2 million.
Reaching $40 by 2030 from roughly $21 this year requires about 17% annual growth, more than double the current pace. The two catalysts management previously named to close that gap — a recovery in new construction and acquisitions — are still missing, as the fourth-quarter plan assumes no construction rebound and nine-month acquisition spending is zero.
What to watch: initial 2027 earnings outlook in February. Another year of single-digit or low-double-digit growth would push the required 2028–2030 growth rate above 20% a year.
Risks this quarter didn't answer
Three standing issues from last quarter are not covered in the earnings release and await the quarterly filing or conference call.
- Extended-warranty cash deferrals: fell 7.7% in the first half even as sales grew; the third-quarter filing's contract-liability note will show whether warranty attachment is still slipping.
- Chemical supply disruptions: suppliers declared shortages on insulation chemicals last quarter; the call will show whether CWT faced volume limits beyond higher prices.
- Large acquisition policy: after market rumors of a bid for Owens Corning last quarter, the release repeated the bolt-on deal criteria without addressing large targets.
💲 Other KPIs
Free cash flow — operating cash flow minus capital spending — fell 29.4% from $392.7 million a year ago, reducing the free cash flow margin to 19.0% from 29.2%. Through nine months, free cash flow is $406.9 million (10.0% of revenue) versus $620.3 million last year, leaving a steep climb to reach the company's 15% full-year margin target.
Overhead and sales costs rose 4.6% from $177.9 million a year ago, growing half as fast as revenue. By our math, that discipline trimmed selling and administrative expenses by 0.5 percentage points of revenue to 12.7%, cushioning a small part of the 2.2 percentage point jump in manufacturing and freight costs.
Factory and equipment spending rose 9.9% from $33.5 million a year ago, equal to 2.5% of third-quarter sales. Nine-month capital spending sits at $106.8 million against $91.3 million last year, running well below the pace needed to spend the roughly $200 million full-year budget.
🔮 Guidance
New. Management expects fourth-quarter sales to grow in the high single digits (about 8% at the middle of the range) from $1,127.7 million a year ago. By our math, that puts full-year revenue growth at about 5.7%, near the top of the prior mid-single-digit full-year plan and driven by price increases and replacement roofing against a weak fourth-quarter 2025 base.
New. The commercial roofing division plans for high-single-digit sales growth in the fourth quarter, matching its 8.4% third-quarter pace. By our math, hitting ~8% in the fourth quarter lifts full-year CCM sales growth to about 5.3%, consistent with the mid-single-digit full-year target set in July.
New. The weatherproofing division also expects high-single-digit fourth-quarter sales growth, slightly below its 9.4% third-quarter growth. By our math, that brings full-year CWT sales growth to about 6.8%, ahead of the prior mid-single-digit full-year plan.
New. The fourth-quarter plan calls for adjusted EBITDA margin to match last year's 22.1%, down from 23.8% in the third quarter on winter seasonality. Because nine-month margin is down 0.8 percentage points at 24.3%, a flat fourth quarter leaves the full-year margin at about 23.8% by our math — down 0.6 percentage points for the year and missing the July plan for a flat full-year margin.
❓ Key Questions
How much did price and volume each add in Q3?
Management said in July that price increases would add mid-single-digit growth in the third quarter and high-single-digit growth in the fourth. Without the exact split, investors cannot tell how much of the 8.8% underlying sales growth was real volume versus price.
How much did factory savings add to CWT in Q3?
The company previously targeted $20 million of full-year savings in weatherproofing from automation, plant closures and in-house resin. With CWT margin rising only 0.6 percentage points against a 2.5-point target, we need the dollar savings achieved this quarter.
Why is the full-year margin table missing from the release?
In July, Carlisle guided for a flat full-year adjusted EBITDA margin of 24.4%. The third-quarter release gives only a fourth-quarter outlook that, by our math, leaves full-year margin down 0.6 percentage points at 23.8%, without stating the full-year cut.
Will full-year free cash flow reach the 15% margin goal?
Nine-month free cash flow is $406.9 million, or 10.0% of revenue. Hitting 15% on roughly $5.3 billion of full-year sales requires about $390 million in the fourth quarter, above last year's $352.1 million despite higher inventory costs.
