Montréal producer of ultra-high-purity specialty semiconductor compounds and wafers — cadmium telluride, cadmium zinc telluride and indium antimonide — plus multi-junction space solar cells, bismuth chemicals and low-melting-point alloys.
Canadian innovation builds a brighter tomorrow.
5N Plus describes itself as "a leading global producer of specialty semiconductors and performance materials", deploying proprietary and proven technologies to develop and manufacture advanced materials that are often core components of its customers' products. Its head office is at 4385 Garand Street, Montreal, with R&D, manufacturing and commercial centres across North America, Europe and Asia. The company states that "Since our founding in 2000, 5N Plus has pursued sustainable growth." Its history page records the origin: a group of employees of a major Canadian mining and metals company started their own company through a management buyout of certain assets, initially founded to provide materials for medical imaging purposes to reduce X-ray exposure.

U.S. Department of War award to establish domestic gallium arsenide electro-optical component production in St. George, Utah
The U.S. Department of War awarded 5N Plus US$7.3 million to expand its St. George, Utah facility with crystal-growth and gallium arsenide compounding equipment. Lockheed Martin is the initial customer partner, and the program covers qualification, low-rate production and a possible follow-on agreement.
Revenue of $122.4 million, up from $95.3 million, with adjusted EBITDA of $26.6 million, net earnings of $19.7 million and a backlog of $420.0 million. Full-year 2026 adjusted EBITDA guidance of $100-105 million was reaffirmed.
Wholly-owned subsidiary AZUR SPACE will add a further 25% capacity in 2026, phased in from the second half of the year, through process optimization and automation in existing space rather than major new capital.
Revised 2025-2026 terms raise cadmium telluride volume commitments by 33%, with a further 25% increase for 2027-2028, plus cadmium selenide deliveries starting in 2026. No contract value was disclosed.
