About GROLLEAU

GROLLEAU is a French industrial group specializing in the design, manufacturing, integration and commissioning of metal energy cabinets, street cabinets, technical shelters and customized solutions for complex operating environments. Historically rooted in telecommunications and power distribution infrastructure, the company has broadened its scope over time to address smart city applications, digital networks, electric mobility and selected critical industrial uses. Grolleau emphasizes its ability to control the full value chain, from engineering to delivery, with production made in France at its Montilliers site in the Maine-et-Loire region. The company positions itself as a leading player in France across several domestic niches, including telecom/energy urban cabinets and on-street EV charging stations, with a stated market share above 50% in certain French segments. Its product portfolio includes power management and distribution cabinets, NRO shelters, outdoor fiber-optic cabinets, micro-data center solutions, standard cabinets for street lighting, traffic signaling, electrical distribution and water treatment, as well as EV charging infrastructure. Grolleau serves a diversified customer base made up of telecom operators, local authorities, large corporations, industrial clients and urban infrastructure players. According to the company’s institutional communication, it has more than 75 years of history, highlighting a long industrial legacy while steadily strengthening its exposure to digitalization and energy-transition themes. In 2023, the group also acquired a 49.9% stake in OMP Mechtron, a European industrial company specialized in mechanical and electronic integration, to expand its industrial footprint and capabilities. On the financial front, Grolleau reported 2024 revenue of €40.0 million, slightly below the 2023 pro forma level, reflecting a less favorable product and geographic mix, while 2025 data showed a return to growth in the fourth quarter. Overall, Grolleau remains a specialized, engineering-led industrial niche player positioned at the intersection of infrastructure, energy, telecommunications and sustainable mobility.
