Hubbell Incorporated (HUBB) Q3 2026 earnings review
Hubbell's data center sales jump, but meter demand falls again
Hubbell, a maker of power grid and commercial electrical gear, is riding data center construction while its smart-meter unit lags. Sales from businesses owned a year ago rose 11%, and total revenue jumped 25% to $1.87 billion on the recent purchase of connector maker NSI Industries. Chief executive Gerben Bakker raised the full-year outlook, which by our math points to 12% underlying sales growth in the fourth quarter.
| Sales from businesses owned a year ago | +11.3% from a year ago (+24.6% total) |
|---|---|
| Profit per share, excluding one-offs | $5.91 +14% from a year ago |
| Electrical Solutions underlying sales | +22.0% from a year ago (+51% total) |
| Full-year profit outlook (excl. one-offs) | Raised $0.10 middle of the range: $20.50 (+13%) |
⚖️ Verdict: 🟢 Bullish
The story got better because Electrical Solutions grew underlying sales by 22% and lifted its profit margin, reversing a first-half margin dip as NSI beat early plans. One caution: Grid Automation shrank 4% against its easiest comparison of the year, and higher deal fees plus interest costs kept standard accounting profit growth to just 4%.
The question now is how much of the third-quarter margin expansion came from a one-time tariff refund rather than ongoing operations. Either data center volume and NSI are strong enough to keep margins up on their own, or profitability will slip back once the refund passes. Fourth-quarter operating margins will tell.
🐂 Bull Case
Data Centers Push Electrical Growth Above 20%
Hubbell's Electrical Solutions division sells wiring, connectors and power gear for commercial buildings, factories and data centers. Chief executive Gerben Bakker said the division's third-quarter results "were highlighted by >20% organic growth in Electrical Solutions, led by strong datacenter markets and bolstered by content gains and capacity expansion investments".
- Sales from businesses owned a year ago: up 22.0% from a year ago, accelerating from 18.3% in the second quarter
- Total division sales: $844.7 million, up 51.2% including acquired businesses
- Division operating margin, excluding one-offs: 24.8%, up 4.0 percentage points from a year ago
This matters because the division suffered a margin drop in the first half of the year from factory reorganization costs and inflation. Higher sales volume, price increases and a tariff refund reversed that drop in the third quarter. The performance also drove management to raise the full-year company outlook.
What to watch: fourth-quarter underlying sales growth in Electrical Solutions. Holding a double-digit pace without the third quarter's tariff benefit would prove that data center demand alone can carry the higher margin.
NSI Integration Beats Initial Plans
Hubbell bought NSI Industries, a maker of electrical connectors and fittings, for $3.0 billion in June 2026 to expand its presence in commercial buildings. In its first full quarter under Hubbell's ownership, Bakker said NSI results were strong and "performance and integration efforts are trending ahead of our initial expectations".
Acquisitions added $162.5 million, or 29.1 percentage points, to Electrical Solutions sales growth this quarter. That beat the roughly $145 million quarterly pace implied by NSI's first-month sales in the second quarter, by our math, and helped lift the division's profit margin excluding one-offs by 4.0 percentage points.
What to watch: management's 2027 profit forecast for NSI in the fourth-quarter report. Staying on track for $0.80 per share of extra profit next year would show the deal is paying for its debt.
Grid Infrastructure Carries Utility Orders
Utility Solutions, Hubbell's larger division at $1.03 billion in quarterly sales, supplies components for electric power lines and substations. Within it, the Grid Infrastructure product group grew sales by about 13% from a year ago, as electric utilities spent money to upgrade aging power lines and connect large new power users.
Bakker said "Orders and end market demand remained strong, driving continued backlog build in the quarter". While the press release did not repeat the first half's 1.2-times ratio of orders to shipments, a growing order backlog means incoming orders still exceeded the $1.03 billion the division shipped.
What to watch: the exact ratio of orders to shipments on the conference call or in the annual report. A reading above 1.0 would confirm utilities are still booking high-voltage gear into 2027.
🐻 Bear Case
Grid Automation Shrinks Against Its Easiest Comparison
Grid Automation makes smart utility meters, sensors and control equipment inside the Utility Solutions division. After five straight quarters of shrinking sales, the unit grew 1% in the second quarter, and management raised the full-year Utility Solutions underlying growth plan to 7% to 9%.
In the third quarter, Grid Automation sales fell about 4% from a year ago. That drop happened against the easiest comparison of the cycle, because sales had fallen 18% in the third quarter of 2025. The reversal dragged total Utility Solutions underlying sales growth down to 4.9%, leaving nine-month underlying growth at 5.7%.
What to watch: fourth-quarter underlying sales growth in Utility Solutions. By our math, the division needs over 9% underlying growth in the fourth quarter just to reach the bottom of its prior 7% to 9% full-year target.
Deal Costs and Interest Eat Up Reported Profit
Hubbell emphasizes profit measures that leave out acquisition accounting and deal fees, because management says those measures show underlying performance better. On that basis, operating margin rose 1.6 percentage points to 25.5% and profit per share grew 14% to $5.91. Under standard accounting, operating margin slipped 0.2 percentage points to 21.8% and profit per share rose only 4% to $4.94.
- Cost of goods sold (cost of making products): 63.2% of revenue, down 0.5 percentage points from a year ago
- Selling and administrative expenses (overhead and sales): 14.9% of revenue, up 0.7 percentage points, including $62.2 million of acquired intangible write-downs
- Net interest expense: $58.0 million, up from $13.6 million a year ago on NSI acquisition debt
The gap matters because interest payments and deal integration costs take real cash. Even as Hubbell raised its full-year profit outlook excluding one-offs by $0.10 at the middle of the range, it raised expected full-year deal and integration costs by the same $0.10 per share, leaving the standard accounting profit midpoint unchanged at $17.40.
What to watch: quarterly net interest expense and deal integration fees in the fourth quarter. A drop in both is required before standard accounting profit can grow at the same pace as operating profit.
Risks this quarter didn't answer
Four standing risks from prior quarters could not be fully tested from the third-quarter press release alone.
- Tariff refund size: both divisions cited a net tariff benefit in the third quarter, but the release did not disclose the dollar amount against the roughly $20 million management previously planned.
- Margin without tariff help: fourth-quarter operating margin in Electrical Solutions will be the first clean test of profitability after the third-quarter tariff refund rolls off.
- Price versus volume: management previously planned on 3 to 4 percentage points of price increases this year, and the quarterly filing will show how much of the 11.3% underlying sales growth came from price rather than volume.
- Tied growth cycles and tough comparisons: data centers and power grid upgrades drive both divisions and the debt paydown plan, and both face their toughest year-ago comparison in the fourth quarter.
👓 Other Themes
Industrial and Residential Markets Stay Soft
Outside of data centers and electric utilities, Hubbell's traditional building and factory markets remain sluggish. In its forward-looking risk disclosures, the company noted "continued softness in the heavy industrial and residential markets of Electrical Solutions". Strong data center orders and the NSI acquisition more than covered for those weaker markets in the third quarter, so they did not hold back overall segment growth.
💲 Other KPIs
Total debt minus cash and investments fell by $209.5 million from the second quarter, when Hubbell borrowed $3.0 billion to buy NSI. Total debt stood at 55% of total capital, down from 58% in June and below the 65% limit in its bank agreements. To save cash for debt paydown, the manufacturer bought back no shares in the third quarter.
Operating cash flow minus factory spending rose 10.5% from a year ago, reversing a slight year-over-year dip in the second quarter. Capital expenditures — money spent on factories and equipment — jumped 38.4% from a year ago to $42.2 million as the group added production lines for data center and power grid gear.
Bills owed by customers rose 35.0% from a year ago and 6.8% from the second quarter, outpacing the 24.6% rise in total third-quarter revenue. Carrying a full quarter of NSI sales and higher third-quarter shipments pushed receivables up, absorbing $253.1 million of operating cash over the first nine months of the year.
🔮 Guidance
Raised. The middle of the range moved up 1.5 percentage points to 18.5% growth, following a 17.1% rise across the first nine months. By our math, the full-year plan leaves about 22.3% total sales growth for the fourth quarter, down slightly from 24.6% in the third quarter. It is the third raise this year: +1.5 points in Q1, +7.5 points on the NSI deal in Q2, and +1.5 points now.
Raised. Hubbell lifted the bottom of the range by 1 percentage point, putting the middle of the range at 10.5% growth. By our math, that implies about 12.1% underlying sales growth in the fourth quarter, up from 11.3% in the third quarter even against a tough 8.9% comparison from late 2025. Fourth straight vintage raise: +1.5 points, +2.5 points, and +0.5 points.
Raised. The middle of the range rose $0.10 to $20.50, or about 12.6% growth for the year. By our math, after earning $15.37 in the first nine months, the outlook leaves $5.13 for the fourth quarter, or 8.5% growth from a year ago against 14.3% in the third quarter. Third raise of the year: +$0.075, +$0.825, and +$0.10.
Unchanged at the middle of the range. Management narrowed the range by $0.05 on each side, keeping the middle at $17.40, or 5.2% full-year growth. Higher expected deal integration costs ($0.60 per share versus $0.50 previously) offset the operational raise. By our math, the plan leaves $4.54 for the fourth quarter, or 8.4% growth from a year ago.
Unchanged. The electrical equipment maker still expects free cash flow to equal about 90% of full-year profit excluding one-offs, as it spends $175 million to $190 million on factory capacity. Over the first nine months, free cash flow of $539.2 million was 66% of adjusted net income ($817.9 million), requiring a seasonally heavy fourth-quarter cash inflow.
❓ Key Questions
How large was the third-quarter tariff refund in dollars?
Management previously guided to a $20 million net benefit in the third quarter from tariff refunds. Because the press release cited a net tariff benefit in both segments without a number, investors cannot tell how much of the 1.6-point margin jump was one-off.
Why did Grid Automation shrink against an easy comparison?
Grid Automation sales fell 4% from a year ago, even though third-quarter 2025 sales had already dropped 18%. Management had called the bottom for this unit in the first half, so the renewed decline raises questions about utility meter demand.
Did Utility Solutions keep its 7% to 9% growth target?
The press release raised the company-wide underlying sales outlook because of Electrical Solutions, but did not update the segment targets. With Utility Solutions underlying growth at 5.7% through nine months, hitting the old 7% to 9% range looks difficult.
What was NSI's standalone revenue and profit margin?
Acquisitions added $162.5 million to Electrical Solutions in the third quarter, and Bakker said NSI beat initial expectations. Without standalone revenue and margin figures for NSI, outside analysts cannot verify the building blocks for next year's $0.80 per share profit target.
