Electrical Distribution EES Adjusted EBITDA Margin

Electrical distribution EES adjusted EBITDA margin measures Wesco's Electrical & Electronic Solutions adjusted EBITDA as a percentage of EES net sales. It is an issuer-defined segment profitability measure, not the same thing as consolidated operating margin or a standardized peer EBITDA margin.

Wesco reported a 9.2% EES adjusted EBITDA margin in fiscal Q2 2026, up from 8.1% a year earlier.

The current-quarter formula is reproducible from $231.3M of EES adjusted EBITDA and $2.511B of EES net sales:

EES adjusted EBITDA margin = $231.3M / $2.511B = about 9.2%

A year earlier, EES generated $182.9M of adjusted EBITDA on $2.258B of sales, or about 8.1%. The margin therefore expanded by roughly 110 basis points.

A 140 bp gross-margin gain was partly offset by SG&A

The EES presentation gives a useful bridge for the margin expansion.

Gross margin increased from 23.0% to 24.4%, a 140 bp improvement. Adjusted SG&A expense moved from 14.9% to 15.2% of sales, a 30 bp headwind.

Those two movements reconcile closely to the 110 bp expansion in adjusted EBITDA margin:

1Gross-margin improvement        +140 bps
2Adjusted SG&A rate change        -30 bps
3Adjusted EBITDA margin change   +110 bps

That is more informative than saying adjusted EBITDA grew faster than sales. It shows that most of the profitability improvement came from gross-margin expansion, while SG&A consumed part of the benefit.

Growth came from both volume and price

EES net sales increased 11.2% year over year, while organic sales increased 10.9%. Wesco attributed the organic increase to roughly 6% volume growth and 5% pricing.

The demand mix was broad but not uniform. Construction grew at a high-single-digit rate, Industrial at a low-single-digit rate, and OEM sales increased more than 20%. Sales to data-center customers increased more than 70%, while non-data-center EES sales still delivered solid high-single-digit growth.

Backlog was also up about 30% year over year, with strong double-digit growth across Industrial, OEM, and Construction.

That context matters for margin interpretation. A higher adjusted EBITDA margin alongside strong volume, price, and backlog can reflect operating leverage and mix, but the company specifically identifies gross-margin expansion as the main bridge in this quarter.

Wesco's segment adjusted EBITDA has a specific reconciliation perimeter

Wesco's chief operating decision maker evaluates its reportable segments using adjusted EBITDA as the segment profit measure. The Q2 2026 EES reconciliation starts with $218.0M of EBITDA, then adds $12.6M of other expense and $0.7M of stock-based compensation to arrive at $231.3M of adjusted EBITDA.

The reportable segments do not incur income taxes or interest expense because those costs are centrally controlled through Wesco's corporate tax and treasury functions. Digital-transformation costs and cloud-computing arrangement amortization shown in Wesco's companywide reconciliation were also recorded at Corporate rather than added to EES in the segment table.

That perimeter prevents two common mistakes. First, the 9.2% EES margin should not be compared directly with another company's consolidated EBITDA margin without reviewing its adjustment policy. Second, company-level adjustments should not be allocated mechanically into EES when Wesco has not assigned them to the segment.

The prior-year reconciliation also deserves attention. Wesco's companywide 2025 adjusted EBITDA definition included restructuring costs that were no longer part of the Q2 2026 definition, although the EES segment table itself shows no restructuring add-back assigned to EES in either comparison shown here.

For current research, pair the margin with EES organic sales growth and EES backlog growth. The three measures together separate current demand, forward order visibility, and profit conversion rather than treating one percentage as the whole segment story.
