The Data-Center Supercycle Powers Legrand’s Breakout First Half of 2026

Legrand, the French conglomerate known for wiring devices, lighting controls, Wiremold and its lighting lines in the electrical distribution segment, who has also built a robust data center offering, announced 1H 2026 earnings on July 29.

Legrand’s record first‑half 2026 performance with about $6.22 billion in sales, +17% sales growth, and +9.8% organic, with 20.8% margin. Growth in North & Central America, now representing 47% of the total group, was +24%, with US growth at +27%, confirming that the electrical industry’s center of gravity has shifted toward data centers, energy transition infrastructure, and digital building systems.

Why Legrand US Growth Matters to Electrical Distributors

For U.S. distributors, Legrand’s results signal a structural demand boom, intensifying competition and accelerating product mix changes across power, connectivity, and digital infrastructure. The drivers of data centers, energy‑transition offerings, and digital infrastructure, now represent 53% of sales.

Data center demand grew over 30% and now accounts for 32% of group revenue. Legrand offers over 140,000 SKUs, centered around busways, PDUs, racks, cable management, cooling interfaces, and digital power monitoring, for data centers and is well positioned to support the development of high-density AI data centers. This growth exceeds typical U.S. electrical market performance (~3–6%), signaling a structural shift toward digital power infrastructure. Although, to be far, much of the performance does not go through electrical distributors.

Drivers of US growth include

• explosive U.S. data‑center demand
• strong adoption of energy‑transition solutions, such as EV charging, power management, digital panels, and
• high-value acquisitions in U.S. power and data‑center markets.

Three acquisitions in particular contributed:

1. Avtron Power Solutions, which specializes in designing and manufacturing load banks and power test solutions for critical power infrastructure, ensuring reliable performance of generators and data center systems
2. Kratos Industries, which specializes in low and medium voltage power distribution, and
3. Girtz Industries, a specialist in the design of power integration solutions, testing, and technical services.

For the Lighting & Lighting Controls business, management noted strong demand for digital lighting controls tied to energy management and continued adoption of connected lighting in commercial buildings.

Tariffs and geopolitical uncertainty (especially China) did not materially impact 1H results, although FX was a –3.7% drag on sales.

Legrand’s data center sales break down into two primary product categories:

1. White Space Solutions – This category includes products for the part of the data center housing active IT components such as server racks, compute, in-room cooling, and power distribution. Legrand is the largest global player in white space equipment, which accounts for over 80% of their data center sales.
2. Gray Space Solutions – This includes infrastructure that supports electrical power provision and protection, such as electrical switchgear, transformers, backup generators, power supply, and cooling systems. Gray space equipment is typically installed early in the data center construction cycle and represents about 20% or less of Legrand’s data center sales. This is the space that electrical distributors, without an “electronics” offering, typically play.

Analyst Concerns Focus on Data Center Sustainability and Margins

Similar to the line of questioning in other earnings calls, the sustainability of data center growth was raised and management reiterated confidence, citing the multi-year AI and hyperscale buildouts, the strength of backlog visibility and the expansion of Legrand’s geographic reach via acquisitions. Chinese softness was a concern, and management noted the weak construction market and that they do not expect any meaningful recovery in 2026. Margin durability amid inflation was raised, with management emphasizing pricing discipline, cost productivity, and high-margin acquisitions. In terms of tariff exposure, management indicated limited impact due to diversified supply chain and strong U.S. manufacturing footprint.

Legrand Raises 2026 Guidance

Legrand raised its 2026 global targets for sales growth (ex‑FX) to +16% to +19% (previously +10% to +15%), organic growth to +8% to +10% (previously +4% to +7%), with acquisition growth ~8% but kept adjusted operating margin unchanged at the: 20.5%–21.0% range. This is one of the most aggressive full-year upgrades among global electrical manufacturers.

Implications for U.S. Electrical Distributors

For the electrical industry, Legrand’s results confirm that data-center electrical infrastructure is the fastest-growing segment in the global electrical market … and not just for switchgear or wire manufacturers

1. Manufacturers are shifting R&D and M&A toward digital power, cooling, connectivity, and monitoring. EV charging, smart panels, and digital power management are becoming core categories for manufacturers and distributors, accelerating product mix changes. Finally, connected wiring devices, access control, and digital lighting controls are becoming standard in commercial projects, reshaping building infrastructure.
2. For US electrical distributors, Legrand’s results illustrate the clear high growth areas data centers, industrial electrification and digital building systems and distributors exposed to these opportunities will outperform traditional construction-focused peers. Additionally, if you are in an area that does not support data centers, due to moratoriums, high energy costs, or geography, odds are that you will underperform the market. Manufacturers need to consider this in evaluating their reps and setting distributor goals.
3. Legrand’s mix shift means distributors must invest in technical sales talent, consider building data-center-specific inventory (there will be MRO business in these “data factories”) and strengthen project management capabilities. The competitive pressure has intensified with Legrand accelerating acquisitions in the US (expect more in 2H 2026), distributors face more integrated manufacturer–service models, faster product cycles, and higher expectations for digital integration (specification tools, BIM, remote monitoring).

Legrand’s 1H 2026 results are more than just a strong earnings story — they are a strategic signal. The electrical industry is being reshaped by data centers, energy transition, and digital infrastructure, and Legrand is positioning itself at the center of this transformation. For U.S. distributors, the message is clear: the future is digital, electrified, and data‑center driven — and the winners will be those who adapt fastest.
