Hubbell Q3 2026: sales up 25% on data centers and NSI, but GAAP EPS rose just 3.6% to $4.94

Hubbell makes the hardware that moves electricity: connectors, insulators, substation gear and meters sold to power utilities (its Utility Solutions segment), and wiring devices, fittings and electrical components used inside buildings, factories and data centers (its Electrical Solutions segment).

In the third quarter of 2026 (July–September), net sales rose 24.6% to $1,872.5 million. About half of that growth was organic (11.3 points, from businesses Hubbell already owned a year ago, excluding currency) and about half was bought (13.2 points, mostly in the segment that took in the $3.0 billion NSI Industries acquisition in June). Diluted EPS rose only 3.6% to $4.94, while adjusted EPS, which strips out acquisition amortization and deal costs, rose 14% to $5.91. The gap between those two numbers is the story of this quarter: the business grew fast, but the cost of paying for NSI and a much higher tax rate absorbed most of it before it reached reported earnings.

Key metrics

Gross margin is worked out from the income statement (gross profit of $688.2 million on $1,872.5 million of sales, against $544.3 million on $1,502.4 million). Adjusted figures exclude amortization of acquisition-related intangible assets and transaction, integration and separation costs. Free cash flow is operating cash flow minus capital spending.

Takeaway: Last quarter the worry was margin: in Electrical Solutions, cost inflation and tariffs ate more than price and productivity recovered. This quarter that reversed. The segment's adjusted margin jumped to 24.8% from 21.2% in Q2 and 20.8% a year ago, with NSI in for a full quarter and 22% organic growth on top. The reported EPS of +3.6% badly undersells that, because it carries the full cost of the NSI financing and a tax rate six points higher than last year's unusually low one.

Segment performance

Electrical Solutions: the growth engine, now with margins to match. Sales rose 51.2%. Organic growth contributed 22.0 points ($123.1 million) and acquisitions 29.1 points ($162.5 million); NSI joined this segment when it closed in June, so this is its first full quarter in the numbers. Adjusted operating income rose 80% to $209.5 million. The release attributes the margin move to "volume growth, the impact of acquisitions, favorable price realization, productivity and a net tariff benefit, partially offset by higher cost inflation and raw material costs." On a GAAP basis margin was flat at 19.8%. The difference is $39.0 million of amortization in the segment this quarter, against $4.8 million a year ago, which mostly reflects writing down NSI's acquired intangible assets (customer relationships, brands and the like) over time.

Utility Solutions: steady, with grid hardware doing the work. Sales rose 8.9% to $1,027.8 million, with 4.9% organic growth that the CEO says was "led by distribution, transmission and substation markets." Inside the segment, Grid Infrastructure (poles-and-wires and substation products) grew about 13%, while Grid Automation (meters and related systems) fell about 4%. The $36.3 million of acquired sales here comes from DMC Power and Nicor, which our Q2 report notes closed in October 2025; DMC passes its one-year mark this month, so from Q4 its sales count as organic. Adjusted margin edged up to 26.0% from 25.7%.

The release gives segment sales, margins and growth rates but not the 10-Q's detail on unit volume versus price, or sales by business group in dollars. The full Q3 10-Q has not been filed yet.

What the headline numbers hide

Tax did more damage to EPS than the acquisition. Pretax income rose 11.0% to $345.3 million, but the provision for income taxes jumped to $80.7 million from $54.4 million. That takes the effective tax rate to 23.4% from 17.5%. The release does not explain the swing, but the prior-year rate looks like the outlier: Hubbell's own full-year guidance assumes an adjusted rate of 22.0–22.5%, and the nine-month GAAP rate is 22.1%. Had Q3 been taxed at last year's rate, net income would have been roughly $20 million higher, about $0.38 a share. So most of the gap between 11% pretax growth and 3.6% EPS growth is a harsh tax comparison, not weaker operations.

The NSI deal costs show up in two places. Net interest expense rose to $58.0 million from $13.6 million, the cost of the roughly $2.8 billion of new long-term debt raised for NSI. Acquisition amortization rose to $62.2 million from $24.7 million ($0.89 a share, versus $0.35). Adjusted EPS adds back the amortization and $5.9 million of transaction and integration costs ($0.08 a share). It does not add back the interest. Keep in mind that the amortization is non-cash but tied to a real $3.0 billion purchase price: the adjusted figure shows how the operations are doing, not what shareholders paid for them.

A "net tariff benefit" is in the margin, size unknown. Both segments list "a net tariff benefit" among the reasons margins improved. Our Q2 report flagged about $30 million of IEEPA tariff refunds Hubbell received after June, which under its accounting are booked only once realized. This release does not say how much of the benefit is refunds versus lower ongoing tariff costs, and its cautionary statements mention "anticipated additional" IEEPA refunds. Part of the margin gain may therefore be one-time; the 10-Q should quantify it.

Cash conversion was solid in the quarter, lighter year to date. Operating cash flow of $322.6 million was 1.23 times net income, and free cash flow of $280.4 million was 89% of adjusted net income. For nine months, free cash flow is $539.2 million against $817.9 million of adjusted net income (66%), short of the ~90% management expects for the full year. Receivables and inventory together used $401.5 million of cash in nine months, versus $185.6 million a year earlier, partly from a bigger business after NSI and partly from growth.

Buybacks played no part. Diluted shares fell only 0.6% to 53.1 million. Repurchases for nine months were $203.5 million, the same figure as the first half in the Q2 10-Q, so Hubbell bought back no stock in Q3. Dividends paid were $75.0 million in the quarter ($225.4 million for nine months less $150.4 million for the first half), up from $70.2 million a year ago.

On balance the quarter is understated: GAAP EPS rose 3.6%, but pretax income rose 11.0% and the tax rate climbed to 23.4% from an unusually low 17.5%; the unquantified tariff benefit is the main thing pulling the other way.

Did last time's read hold up?

Our Q2 report named three things to watch in Q3:

• Would Electrical Solutions' adjusted margin stabilize with NSI in for a full quarter? It did more than stabilize: 24.8%, up from 21.2% in Q2 and 20.8% a year ago.
• How much of the ~$30 million tariff refund would show up? Partly answered. A "net tariff benefit" helped both segments, but the release does not size it.
• How fast would Hubbell pay down NSI debt? It started. Total debt fell to $5,120.2 million at September 30 from $5,372.6 million at June 30, and net debt (debt minus cash and investments) fell to $4,664.7 million from $4,874.2 million. Net debt is now 51% of total capital, against 52% in June and 28% at the end of 2025.

Outlook

Management raised its full-year 2026 guidance, "primarily driven by stronger anticipated Electrical Solutions growth":

The gap between GAAP and adjusted EPS is now about $2.50 a share of amortization and about $0.60 of transaction, integration and separation costs (up from about $0.50). Guidance assumes a 22.0–22.5% adjusted tax rate, about $20 million of restructuring, and free cash flow of about 90% of adjusted net income. CEO Gerben Bakker says orders "remained strong, driving continued backlog build in the quarter."

Our read: With nine-month adjusted EPS at $15.37, the new range implies $5.03–$5.23 for Q4, below Q3's $5.91. The release does not explain the step-down, so it is the number to test against the Q4 report. Three things to watch:

• Electrical Solutions organic growth. Management's raise depends on it. A 22% rate in Q3 sets a high bar, and the release's cautionary statements still flag "continued softness in the heavy industrial and residential markets."
• The tariff line. The 10-Q should say how much of Q3's margin came from refunds; if it is large, Q4 margins may look weaker by comparison.
• Cash. Reaching ~90% free cash flow conversion for the year means converting well over 100% of Q4 adjusted net income, which would also speed up debt paydown.
