Hammond Power Solutions

What Hammond Power Solutions does

Hammond Power Solutions Inc. (HPS) is a Canadian designer and manufacturer of dry-type transformers and related magnetics, founded in 1917 and headquartered in Guelph, Ontario. The company produces standard and custom transformer solutions across low- and medium-voltage classes (up to 46kV), as well as power quality equipment including harmonic filters, reactors, sinewave motor protection filters, and active/passive harmonic compensation products. HPS maintains an engineering database of over one million designs and creates more than 9,000 custom designs annually, supported by 50+ engineers and technicians at its Guelph design center. HPS holds the position of largest dry-type transformer manufacturer in North America.

HPS operates seven manufacturing facilities across Canada (Guelph, Walkerton, Granby), the United States (Baraboo, Compton), and Mexico (Monterrey), supported by nine regional warehouses that enable 48-hour delivery of standard stocked product to 90% of customers. The portfolio serves customers in data centers, renewable energy, EV charging infrastructure, oil and gas, mining, commercial construction, and healthcare across more than 50 countries. Distribution is hybrid: direct enterprise sales offices handle custom and large accounts, while channel partners — Affiliated Distributors (618 members), IMARK (1,100+ distributors), Rockwell Automation's PartnerNetwork, and Electro-Federation Canada — provide broad mid-market reach, supplemented by the HPS E-Portal and product configurator.

The business model is anchored in quote-based hardware sales of standard catalog products and custom-engineered solutions, with pricing not publicly disclosed. HPS reported record FY2025 sales of $898.3 million (a 13.9% increase year-over-year) and Q1 2026 sales of $264.8 million (a 31.5% increase year-over-year), with record FY2025 adjusted EBITDA of $133.3 million and a backlog that grew 122% year-over-year. HPS is publicly traded on the Toronto Stock Exchange under ticker HPS.A and is currently executing the announced C$365 million all-cash acquisition of AEG Power Solutions (expected to close in Q2 2026), which will add approximately C$326 million in annualized revenue, 780+ employees, and five manufacturing facilities across Europe and Asia.
