Data‑Center Expansion and Grid Modernization Propel US Electrical Equipment Parts Theme

October 29, 2026

The US Electrical Equipment Parts theme rose 7.8% over the past five days and 18.8% in the last three months, while six‑month performance is down 1.6%. The rally reflects a convergence of strong demand from data‑center builders, aggressive grid‑modernization programs, and policy‑driven renewable‑energy investment, offset by lingering supply‑chain constraints and rising raw‑material costs.

Data‑Center Build‑Out Fuels Short‑Term Upswing

Rapid expansion of AI‑driven workloads has spurred a wave of data‑center construction across the United States. Companies such as Microsoft, Google and AWS are signing long‑term production agreements that require large volumes of high‑reliability power equipment. This demand has lifted top performers like GrafTech International Ltd. (NASDAQ: GTLS), which posted a three‑month gain of 72.5%, and Prysmian S.p.A., up 48.0%. The sector‑wide sales growth for the trailing twelve months ended Q1 2026 averaged 10.5%, underscoring the strength of this demand tailwind.

Grid Modernization and Renewable Energy as Medium‑Term Tailwinds

U.S. utilities face the replacement of more than 40 million aging distribution transformers, many of which are past their design life. Federal initiatives—including the Inflation Reduction Act, the Defense Production Act, and the Grid Resilience and Innovation Partnerships (GRIP)—are channeling billions into transmission, distribution and renewable‑energy integration. Companies such as Atkore Inc. (+33.4%) and Preformed Line Products (+23.1%) are benefitting from these projects. Sector‑wide operating margins remain healthy at 8.2%, while gross profit margins sit at 30.1%, reflecting the profitability of large‑scale infrastructure contracts.

Supply‑Chain Constraints and Raw‑Material Costs as Headwinds

The sector continues to grapple with elongated lead times and part shortages. Copper prices have risen over 70 % since 2020, driving transformer prices up roughly 100 % in the past five years. Tariffs on imported electrical components—currently 15 % and slated to increase to 25 % after 2027—add further cost pressure. These constraints have hurt bottom performers such as Eos Energy Enterprises (‑37.9%) and FuelCell Energy (‑31.5%). Net‑debt‑to‑EBITDA for the sector averages 1.3, while interest coverage stands at 2.4, indicating modest financial flexibility amid rising input costs.

Sector Fundamentals and Valuation Context

Despite short‑term volatility, the underlying fundamentals remain solid. The trailing‑year return on equity averages 9.0% and return on assets 3.5%. Free‑cash‑flow‑to‑sales stands at 5.8%, and free‑cash‑flow‑to‑EBITDA at 81.3%, underscoring strong cash generation. Investors should monitor policy developments, especially tariff adjustments and IRA‑related incentives, as they will shape the risk‑reward profile over the coming months.
