Wesco International (WCC) Q3 2026 earnings review
Wesco raises its sales plan, but its cash target stalls
Wesco International, the industrial and electrical distributor, grew faster inside data centers and across its traditional markets at once. Revenue rose 17% from a year ago to $7.2 billion, while profit per share excluding one-offs climbed 47%. Chief executive John Engel raised the full-year profit and sales outlook for a third straight quarter, as the order backlog jumped 80%.
| Sales from businesses owned a year ago | +16.6% $7.23B total sales |
|---|---|
| Data center sales | $1.8B +55% from a year ago |
| Profit per share, excluding one-offs | $5.77 +47% from a year ago |
| Full-year sales outlook | Raised $800M middle of the range: 14.4% growth |
⚖️ Verdict: 🟢 Bullish
The story got better because growth broadened into electrical equipment and finally lowered overhead costs as a share of sales. Sales outside data centers rose 7%, and higher volume pushed operating margins up by a full percentage point. One caution: management left its full-year free cash flow target unchanged at $300 million to $600 million, which by our math leaves only $20 million for the fourth quarter.
The question now is whether the 80% backlog jump turns into cash next year or stays tied up in inventory and unpaid customer bills. Either multi-year projects convert smoothly and lift cash flow, or funding large orders keeps absorbing most of the profit gain. Fourth-quarter cash generation and the 2027 outlook in February will settle it.
🐂 Bull Case
Data Center Demand Expands Into Electrical Equipment
Wesco supplies the wiring, switchgear, cooling and server-room hardware inside large computing facilities. Management wants customers to buy both server-room gear and building-wide power systems from its catalog. Critics worry that relying so heavily on a handful of giant tech buyers leaves the distributor exposed if construction slows.
Sales to data centers reached $1.8 billion this quarter, up about 55% from a year ago. In Electrical and Electronic Solutions (EES, the unit selling building power and industrial gear), data center revenue more than doubled. Management raised its full-year data center growth target to over 40%, up from over 30%.
- Data center revenue: $1.8 billion in Q3, up from $1.5 billion last quarter
- Share of total sales: about 23% over the past twelve months, or roughly $6 billion
- Communications and Security Solutions (CSS, the network and security unit): data center sales up about 40%
The expansion into electrical gear matters because building power projects carry higher profit margins and pull in extra service work. By our math, data centers provided 58% of the company's total dollar sales gain this quarter, so concentration remains high even as the product list widens.
What to watch: fourth-quarter data center revenue in dollars. A drop below the $1.8 billion third-quarter run-rate would show that major tech customers are pausing orders after a two-year building spree.
Backlog and Non-Data-Center Sales Accelerated Together
"The past five consecutive quarters of double-digit sales growth demonstrate Wesco’s higher growth profile which extends well beyond our important data center positioning," chief executive John Engel said. Critics had questioned whether traditional industrial, construction and utility buyers were actually growing alongside the computing boom.
Revenue outside data centers grew 7% from a year ago, stepping up from roughly 5% last quarter. Meanwhile, the backlog of unshipped customer orders jumped about 80% from a year ago, setting a record in all three business units.
- Communications and Security Solutions backlog: up about 140% from a year ago
- Utility and Broadband Solutions (UBS, the power-grid and telecom unit) backlog: up about 90%, led by grid services
- Electrical and Electronic Solutions backlog: up about 40%, with original equipment manufacturer sales up about 30%
Engel attributed the order book to "multi-year customer commitments" across power, electrical and communications markets. That supports the claim of broader demand, because EES construction sales grew in the mid-teens and investor-owned utilities bought more grid equipment.
What to watch: the 2027 sales outlook issued with fourth-quarter results in February. It will show how much of the 80% backlog jump ships next year rather than sitting in multi-year schedules.
Higher Volume Finally Lowered Overhead Costs
For several quarters, overhead costs grew faster than revenue even as sales climbed. Management blamed employee commissions and software investments, promising that higher volume would eventually outpace office and warehouse expenses.
In the third quarter, selling, general and administrative expenses (advertising, payroll and overhead) rose 15.1% to $1,062.4 million, driven "due to an increase in commissions and incentives due to company performance, as well as higher salaries and benefits". Excluding software overhaul charges, overhead fell 0.3 percentage points to 14.4% of sales.
Gross margin (profit after the cost of products sold) also rose 0.4 percentage points to 21.7% on better pricing in electrical and communications gear. Together, product margins and overhead savings lifted EBITDA margin excluding one-offs by 1.0 percentage point to 7.8%. One quarter fades the cost concern, but nine-month overhead is still flat at 14.9% of sales.
What to watch: fourth-quarter overhead as a share of sales. Another year-over-year drop would confirm that revenue growth is now outrunning payroll and commission increases.
🐻 Bear Case
Working Capital Still Holds Back Full-Year Cash
"We are particularly pleased with our free cash flow generation during the quarter which was strong given the sales growth we delivered," Engel said. Free cash flow reached $184.2 million, turning around a $89.3 million cash outflow a year ago and bringing nine-month cash generation to $429.9 million.
Yet the distributor left its full-year free cash flow forecast unchanged at $300 million to $600 million, even as it raised its full-year sales plan by $800 million at the middle of the range. Three months ago, management had cut that same cash target from $500 million to $800 million.
- Nine-month inventory build: $704.9 million cash outflow to stock large projects
- Nine-month customer receivables build: $1,003.5 million cash outflow from rising sales
- Customer deposits and supplier payables: $1,152.3 million payable inflow plus "advance payments from customers and milestone billings"
The unchanged outlook cuts against Engel's upbeat cash framing. By our math, the $450 million middle of the full-year range leaves only about $20 million of free cash flow for the fourth quarter, because funding new inventory and unpaid customer bills eats up the extra profit.
What to watch: fourth-quarter free cash flow against the $450 million full-year midpoint. A weak finish would keep the company's earlier $3 billion three-year cash goal out of reach.
Software Overhaul Costs Keep Growing Outside Headline Profit
Wesco is building a company-wide software system to unify its warehouses and sales offices. When calculating its headline profit measures, the distributor strips out both the direct spending on this digital overhaul and the amortization of cloud software setup costs.
In the third quarter, digital overhaul charges more than doubled to $24.8 million from $10.4 million a year ago. Cloud software amortization added another $12.6 million, up from $9.0 million. Management also raised its full-year stock-based compensation add-back to about $75 million, up from $70 million in July.
Over the past twelve months, the digital and cloud exclusions totaled $121.8 million by our math, or nearly 7% of headline EBITDA. These are ongoing cash and software expenses required to run a modern distributor, and management has given no end date for the project.
What to watch: the 2027 outlook assumptions in February for digital overhaul and cloud amortization charges. Another increase would mean the software project is becoming a permanent cost.
Risks This Quarter Didn't Answer
Three standing questions about project margins, order conversion and acquisition accounting remained open in the third-quarter release and presentation.
- Utility gross margin: UBS gross margin stayed flat from a year ago at 17.8%; the presentation said "Public Power competitive market dynamics have stabilized throughout the year", but year-over-year price pressure remained a headwind.
- Backlog dollar value and delivery schedule: management reported backlog only as an 80% growth rate, so investors still cannot calculate how much ships in 2027 versus later years.
- Newark Engineering Group accounting: the preliminary purchase price breakdown due this quarter does not appear in the release and awaits the quarterly SEC filing.
👓 Other Themes
Supplier Price Increases Add More to Sales
Higher product prices added about 3 percentage points to third-quarter revenue growth, led by a 5% price lift in electrical equipment, while unit volumes grew across all three divisions. Management raised its full-year pricing assumption to about 3 percentage points of sales growth, up from 2 points in July, and continued to assume no Federal Reserve interest rate cuts in 2026.
💲 Other KPIs
Net debt divided by twelve-month EBITDA excluding one-offs fell to 2.8x, down from 3.0x last quarter and 3.4x at the end of 2025. Total debt net of cash was $5,215.7 million, down slightly from $5,224.6 million at year-end, so higher operating profit drove the improvement.
Customer receivables plus inventory minus supplier payables rose 14.0% from a year ago by our math, up from $5,362.7 million last quarter. Averaged over four quarters, working capital sat at 20.2% of twelve-month sales, nearly unchanged from 20.3% in the second quarter.
Weighted-average diluted shares edged down 0.4% from 49.5 million a year ago. The electrical distributor spent $75.0 million on common stock buybacks over the first nine months, matching last year's pace to offset employee stock awards.
🔮 Guidance
Raised. The middle of the range moved up $800 million to $26.9 billion, or 14.4% growth by our math. That leaves about 14.2% growth for the fourth quarter, down from 16.6% in the third quarter. It is the third raise this year: +$200 million, +$850 million, +$800 million.
Raised. The middle of the underlying sales plan moved up 3.5 percentage points to 13.5% growth. By our math, that leaves about 12.4% underlying growth for the fourth quarter, even though preliminary October sales per workday grew in the high teens.
Raised. Management lifted the full-year margin target by 0.2 percentage points at the middle of the range. After delivering 7.2% over the first nine months and 7.8% in the third quarter, the target points to a seasonal fourth-quarter dip to 7.2%.
Raised. The middle of the range rose $1.50 to $18.25, or 41.4% growth by our math. That leaves $4.55 per share for the fourth quarter, up 33.8% from a year ago. Third raise this year, and each was larger: +$0.50, +$0.75, +$1.50.
Unchanged. Management kept the cash target where it was after cutting it by $200 million in July. With $429.9 million already collected in the first nine months, the $450 million middle of the range leaves just $20.1 million for the fourth quarter by our math.
New. The fourth-quarter plan calls for roughly 13% sales growth at the middle of the range, aligned with the 14.2% implied by the full-year dollar target. That is slower than the third quarter's 16.6% pace and October's high-teens start.
New. Adding 0.5 percentage points to last year's 6.7% fourth-quarter margin puts the target at 7.2% by our math. That is 0.6 percentage points below the third quarter's 7.8% reading due to normal winter seasonality.
