Hubbell Inc (HUBB) | The Buildout — AI Infrastructure
The Verdict
Hubbell makes the electrical and utility hardware that moves and manages power — connectors, insulators, switches, enclosures, arresters, smart meters, and modular power skids. Its Utility Solutions segment supplies equipment that goes on transmission lines and in substations; its Electrical Solutions segment supplies components inside buildings and data centers. In the AI buildout, Hubbell is a second-derivative supplier: data centers need power, and power needs transmission, substations, and balance-of-system electrical gear. The company does not present itself as an AI company, and management does not disclose AI-specific revenue.

What We Like
- Data-center sales grew approximately 65% in Q2 2026, up from ~40% in Q1; the full-year data-center outlook was raised to ~50% from more than 25%.
- Utility first-half book-to-bill ran ~1.2x, with orders booked into 2027, particularly in transmission and substation.
- The $3.0B NSI Industries acquisition closed in early June 2026, expected to add ~$0.20 of adjusted EPS accretion in 2026 and ~$0.80 in 2027.
- Management introduced 765 kV high-voltage transmission as a market: ~$1.5B addressable over ten years and ~7,000 miles, with Hubbell saying it serves 85% to 90% of material on a transmission line.
- Full-year guidance was raised twice in two quarters, lifting organic growth to +9-11% and adjusted operating margin to 23.1-23.4% (a 40-70 bps expansion).
What We’re Watching
- Electrical Solutions adjusted operating margin fell 130 bps y/y in Q2 2026 to 21.2%; management guides to expansion in both Q3 and Q4 2026 and declined to say whether it holds excluding the IEPA/tariff benefit.
- The $20M IEPA/tariff net benefit is dated to Q4 in prepared remarks and Q3 in Q&A — unreconciled on the call.
- Pro forma net debt/EBITDA stands at ~2.9x after NSI, with deleveraging planned over 24-30 months against capital expenditures of $175-190M.
- Free cash flow conversion was reset to ~90% 'for the next couple of years' because capex is now 2.5-3% of sales versus under 2% historically.
On the demand side the thesis is strengthening: data-center growth accelerated from ~40% to ~65%, utility book-to-bill ran ~1.2x, and guidance was raised twice in two quarters. The margin side is less clean — Electrical margin fell 130 bps y/y despite 18% organic growth, the full-year margin guide leans on a one-time IEPA/tariff benefit, and management declined to reconcile the ex-benefit picture. The open question is whether Electrical margin expands in Q3 and Q4 2026 on its own.
Earnings Beat
Hubbell reported Q2 2026 net sales of $1.712B, up 15% year over year — 10% organic plus 5 points from acquisitions. Gross margin was 35.8%, down from 37.2% in the prior-year quarter. Adjusted operating profit was $409M, up 13%, for a 23.9% adjusted operating margin, a modest contraction; adjusted diluted EPS was $5.52, up 12%. The standout metric was data-center sales, up approximately 65%, which lifted the full-year data-center outlook to about 50%.
| Metric | Q2 FY2026 | Q1 FY2026 | Q2 FY2025 | YoY |

Data center sales were up approximately 65% in the quarter as capacity additions, new product introductions and content gains drove outgrowth in a strong underlying market.— Joe Capozzoli, Chief Financial Officer, 2026-07-28
Management tone: Across the two calls in evidence, management's tone became more specific and more confident. Q1 2026 introduced a new high-voltage market and raised guidance, but trimmed the full-year margin outlook to ~20 bps and framed price/cost as dilutive. Q2 2026 reversed that: it raised the margin outlook to 40-70 bps, closed the NSI acquisition, and more than doubled the data-center outlook. Grid Automation's framing moved from stabilization to recovery. Management was mostly direct in Q&A, but declined to quantify whether Electrical margin would expand excluding the IEPA/tariff benefit and left the IEPA refund timing unreconciled between Q3 and Q4.
Management Guidance
Management guided FY2026 total sales growth to +16-18% and organic growth to +9-11%, with about 5 points of the total coming from the NSI acquisition. Adjusted operating margin is guided to 23.1-23.4%, a 40-70 bps expansion, including ~30 bps from the net IEPA/tariff benefit and ~40 bps from NSI. Adjusted EPS is guided to $20.25-$20.55. Other assumptions: net interest expense of ~$170M; an adjusted tax rate of 22.0-22.5%, with ~24% in Q3 on discrete items; capital expenditures of $175-190M; restructuring of ~$20M, back-half loaded; and free cash flow conversion of ~90%. Data-center growth is guided to ~50% for the year.
Trajectory
Revenue is accelerating. Net sales were $1.493B in the December 2025 quarter, $1.517B in Q1 2026, and $1.712B in Q2 2026 — a 12.9% sequential increase. The organic pace also stepped up, from +8% in Q1 to +10% in Q2, and the full-year organic guide rose to +9-11%. Data-center sales drove much of it, up ~40% in Q1 and ~65% in Q2. Margins are mixed: gross margin was 33.3% in Q1 and 35.8% in Q2, while the adjusted operating margin of 23.9% in Q2 was a modest contraction on a difficult comparison. Electrical Solutions margin fell 130 bps y/y despite 18% organic growth.
The Model
The model projects FY+1 revenue of $6,880M and EBITDA of $1,734M, a 25.2% margin, then FY+2 revenue of $7,835M and EBITDA of $2,025M, a 25.85% margin. The near term is anchored by the raised full-year guidance — organic growth of +9-11%, data-center growth of ~50%, and about 5 points of sales from the NSI acquisition. FY+2 depends on transmission and substation orders already booked into 2027 converting, first 765 kV shipments beginning in 2027, and NSI synergies landing.

Projections are the median of 4 independent model runs. The model’s revenue sits 11.1% above analyst consensus.
Management guided FY2026 total sales growth to +16-18% and organic growth to +9-11%, with about 5 points of the total coming from the NSI acquisition. Adjusted operating margin is guided to 23.1-23.4%, a 40-70 bps expansion, including ~30 bps from the net IEPA/tariff benefit and ~40 bps from NSI. Adjusted EPS is guided to $20.25-$20.55. Other assumptions: net interest expense of ~$170M; an adjusted tax rate of 22.0-22.5%, with ~24% in Q3 on discrete items; capital expenditures of $175-190M; restructuring of ~$20M, back-half loaded; and free cash flow conversion of ~90%. Data-center growth is guided to ~50% for the year.
What Could Go Right — and Wrong
- Data-center growth holds near ~50% and capacity additions of roughly $25M per quarter come online, letting more of the booked-out long-cycle skid business ship.
- Utility book-to-bill stays at or above ~1.0x, with 2027 orders continuing to build in transmission and substation.
- Electrical Solutions margin returns to expansion in Q3 and Q4 2026 — and holds even excluding the one-time IEPA/tariff benefit.
- NSI synergies land at or above 2-3% of sales and 3-5% of cost over three years, with accretion at or above $0.20 in 2026 and $0.80 in 2027.
- 550 kV components ship in the second half of 2026 and the first 765 kV shipments begin in 2027, converting the ~$1.5B high-voltage opportunity into revenue.
- Transmission and substation project timing slips, undercutting the orders-into-2027 claim and the second-half utility acceleration, which management guides to double-digit full-year growth.
- Electrical margin fails to expand in Q3 and Q4 2026 — a second consecutive miss after the 130 bps y/y decline in Q2 — calling the recovery into question.
- Price/cost stays margin-dilutive, pressuring a full-year margin guide that leans on ~30 bps of one-time tariff benefit and ~40 bps of NSI.
- NSI integration or deleveraging disappoints, with cash conversion stuck below ~90% and leverage of ~2.9x not falling on the 24-30 month path.
- Data-center growth decelerates sharply from ~50%; read-throughs show peers stepping down, such as WESCO's data-center growth easing from ~+70% to ~+45%.
Looking Ahead
Over the next 12 months, the tests are specific: whether Electrical Solutions margin returns to expansion in Q3 and Q4 2026, where the IEPA/tariff benefit actually lands, and whether data-center growth holds near ~50%. Utility orders already booked into 2027 and first-half book-to-bill of ~1.2x support the multiyear transmission and distribution cycle. Capacity additions at roughly $25M per quarter and capital expenditures of $175-190M are the levers for converting demand. Management says it will share its long-term strategy at an investor day on March 4, 2027, at its Centralia, Missouri training center.

Business Segments
Competitive Landscape
Hubbell competes in electrical and utility equipment, a field of large diversified manufacturers. Peer filings place it in several competitor sets: ABB's Electrification business, Atkore's Safety & Infrastructure group, and TE Connectivity's Industrial Solutions segment all name Hubbell as a competitor. In a few areas management describes a stronger-than-commodity position — Hubbell says it serves 85% to 90% of the material on a transmission line, DMC Power's crimp connector replaces a field weld, and Systems Control builds substation control houses in a factory. But the company says it is 'not typically a backlog driven business,' and its products are largely specified components rather than sole-source systems.
