Bentley Systems, Incorporated, the infrastructure engineering software company, announced that it has entered into a definitive agreement with investors led by Accel-KKR to acquire Seequent—a leader in software for geological and geophysical modeling, geotechnical stability, and cloud services for geodata management, visibility, and collaboration—for $900 million in cash, subject to adjustment, plus 3,141,361 BSY Class B shares.

The acquisition of Seequent is expected to initially add approximately 10% to each of Bentley Systems’ key financial metrics (ARR, annual revenue, and EBITDA) and is expected to be measurably accretive to Bentley’s organic growth rate. Most significantly, the combination will deepen the potential of infrastructure digital twins to help understand and mitigate environmental risks, advancing resilience and sustainability.

The acquisition is subject to customary closing conditions and regulatory approvals, including New Zealand Overseas Investment Act consent as well as clearance under the Hart-Scott-Rodino Antitrust Improvements Act. Upon closing, Seequent will operate as a stand-alone Bentley subsidiary, with Seequent’s current Chief Operating Officer Graham Grant, succeeding its retiring CEO Shaun Maloney, reporting to Bentley’s Chief Product Officer Nicholas Cumins.

Seequent, founded and headquartered in Christchurch, New Zealand, has more than 430 colleagues in 16 office locations, serving geologists, hydrogeologists, geophysicists, geotechnical engineers, and civil engineers in over 100 countries, and the world’s top mining companies. Its established presence in mineral-intensive geographies such as South America and southern Africa is expected to accelerate Bentley’s overall opportunities in these regions with significant infrastructure requirements. In turn, Bentley’s established presence in China, and its mainstay reach across civil engineering sectors, is expected to accelerate Seequent’s expansion in new markets.

Subsurface conditions comprise the “infrastructure of our infrastructure” and literally underlie the earth’s major environmental risks. Bentley current offerings enable digital twins to incorporate what’s constructed “near surface,” including foundations, drainage facilities, buried utilities, tunnels, and subsea structures. The addition of Seequent will now make it possible for infrastructure digital twins to reach full subsurface depths, augmenting environmental resilience against flood, seismic, climate, and water security threats.

Seequent first applied implicit modeling technology to geological science more than 15 years ago, using mathematical tools to derive and visualize 3D geological models from measured data and user interpretation. This software advancement caused a “leapfrogging” paradigm shift in the understanding of the earth’s subsurface and has been increasingly adopted by geoscientists and researchers around the world to uncover and visualize valuable insights about environmental conditions and challenges.

Seequent’s products include Leapfrog, its leading product for 3D geological modeling and visualization, Geosoft for 3D earth modeling and geoscience data management, and GeoStudio for geotechnical slope stability and deformation modeling. Bentley’s complementary geotechnical engineering software portfolio, including PLAXIS, gINT, and OpenGround, will be integrated in due course to support open digital workflows from borehole and drillhole data to geological models and geotechnical analysis applications.

The mining industry, with its economic sensitivity and environmental responsibilities, was the first and fastest to adopt 3D earth modeling, superseding traditional 2D processes to speed and improve decision cycles. A mine is at once a never-ending and continuously changing infrastructure construction project, and a valuable and environmentally critical infrastructure asset. Seequent recognized the potential, for ALL major infrastructure engineering projects and assets, to likewise “leapfrog” traditional 2D subsurface modeling and simulation processes. Leapfrog’s usage, often in conjunction with Bentley’s software offerings, has been growing consistently in civil infrastructure sectors.

The integration of Bentley’s and Seequent’s solutions, for deeper infrastructure digital twins, can contribute a multiplied “ESG handprint” to improve the world’s environment while improving the world’s economies. While Seequent’s products aren’t appreciably used in oil and gas exploration or production—which is served by its own dedicated industry of specialized geophysical software—imperatives for energy transition present new opportunities, even beyond the expansion of mining to produce the materials needed for widespread electrification. Seequent is a leader in 3D modeling for geothermal energy sources, and its software and cloud services provide the important geosciences context for water resources simulations and environmental engineering.
