Convent-backed Movares Acquires INNAX to Accelerate Energy Transition in Buildings

Movares Group B.V., a Dutch engineering and consultancy firm specializing in infrastructure and sustainable urban development backed by Dutch private equity firm Convent, has acquired INNAX Group B.V., a company focused on energy performance, monitoring, and realization of sustainability measures. The transaction, announced on June 1, 2026, aims to create an integrated organization capable of delivering scalable, data-driven solutions for the energy transition in the built environment.

The acquisition involves a full 100% stake in INNAX, with the deal expected to close in the third quarter of 2026. While financial terms were not disclosed, the integration will add approximately 400 professionals to Movares’ workforce, significantly expanding its capacity in sustainable building projects.

Movares, headquartered in Utrecht, Netherlands, offers engineering, design, and consultancy services across infrastructure, energy, and buildings. The company is known for its expertise in system integration, planning, and engineering with a strong emphasis on data and scalable solutions. INNAX complements this with its specialization in energy performance, digital monitoring, and implementation of sustainability measures, focusing on data and digitalization to optimize building energy use.

Barbara Visser, CEO of Movares, highlights the strategic rationale: “The energy transition in the built environment requires speed and scale. By combining Movares’ design and engineering capabilities with INNAX’s expertise in energy performance and digital solutions, we can offer clients integrated, scalable services that accelerate their sustainability goals.”

The combined entity will be among the first in the Netherlands to provide end-to-end services covering strategy, design, financing, realization, and ongoing monitoring of sustainable building projects. This integrated approach aims to reduce project lead times, lower costs, and deliver measurable CO₂ reductions.

Paul ten Kroode, COO of Movares, adds, “The built environment is a major contributor to CO₂ emissions. Our enhanced capabilities will enable faster progress toward Paris Agreement targets, leveraging innovation and digitalization to create Paris Proof buildings that maximize societal value.”

Market trends show increasing demand for sustainable, energy-efficient buildings driven by regulatory pressure, rising energy costs, and grid constraints. Movares and INNAX’s combined offering positions them to capture growth opportunities in green infrastructure and energy transition projects, both domestically and potentially across Europe.

Financial details such as valuation and multiples remain undisclosed. The transaction is expected to generate synergies through cross-selling, operational efficiencies, and enhanced innovation capacity. Integration challenges include aligning corporate cultures, IT systems, and retaining key talent.

Jörgen Waagenaar, General Director of INNAX, states, “Joining Movares allows us to scale our impact and better support clients in achieving Paris Proof status while building on our strong foundation.”

Following completion, Movares plans to integrate INNAX’s services fully, offering clients a seamless experience from ambition to verified sustainability outcomes. Regulatory approvals are anticipated without significant hurdles.

This acquisition marks a significant step for Movares toward market leadership in sustainable urban engineering and energy transition consultancy, reinforcing its commitment to innovation and comprehensive client solutions.
