NemetschekAcquirer
Nemetschek Group completed its acquisition of Heavy Construction Systems Specialists LLC (HCSS) on July 1, 2026, adding the heavy‑civil software provider to its Build & Construct segment and granting Thoma Bravo a 28% minority stake in that segment.
Deal Terms
Nemetschek Group has completed its acquisition of Heavy Construction Systems Specialists LLC (HCSS), adding the firm to its Build & Construct segment and giving private‑equity owner Thoma Bravo a 28% minority stake in the segment. The transaction value was not disclosed. Nemetschek refinanced HCSS’s existing debt and liabilities, an action that impacted the group’s net‑debt position by roughly €450 million.
Company Profiles
HCSS, founded in 1986 and headquartered in Sugar Land, Texas, delivers construction‑software solutions to the infrastructure and heavy‑civil markets in North America. In 2025 the company generated about $215 million in revenue, posted annual recurring revenue (ARR) growth of roughly 21%, and recorded an EBITDA margin near 40%. The firm serves more than 4,000 customers and employs over 550 people.
Nemetschek Group, a global provider of architecture, engineering and construction (AEC) software, operates the Build & Construct segment alongside Bluebeam, GoCanvas (including SiteDocs) and Nevaris. The segment targets a construction‑software market projected to reach $12 billion by 2028.
Strategic Rationale
The acquisition expands Nemetschek’s construction‑software portfolio across the full project lifecycle, from office‑based design to field execution. HCSS’s data‑rich platform and deep sector focus are expected to accelerate AI‑driven product development across the segment. Cross‑selling opportunities arise from the combined customer base, while broader channel access should improve market penetration beyond North America. Retaining Thoma Bravo as a 28% shareholder aligns the private‑equity firm’s incentives with the long‑term growth of the Build & Construct unit, potentially facilitating future co‑investment or add‑on deals.
Outlook
Nemetschek plans to extend HCSS’s reach into international markets, leveraging its existing global sales infrastructure. The integration also positions the group to capture a larger share of the $12 billion construction‑software market, particularly as AI‑enabled analytics become a differentiator for infrastructure owners and contractors.
Why It Matters
For Nemetschek, the deal deepens its foothold in heavy‑civil construction software, a segment where competitors such as Autodesk and Procore have been expanding AI capabilities. The added ARR and high‑margin profile of HCSS should lift the Build & Construct segment’s overall profitability and give the group leverage to bundle solutions across design, field, and compliance workflows. Thoma Bravo’s 28% stake turns the private‑equity firm from a seller into a strategic partner, ensuring continued capital support and potential follow‑on investments. Competitors will now face a more integrated suite that can cross‑sell between office and field, potentially accelerating customer migration toward platforms that combine AI‑driven analytics with end‑to‑end project management.
Key Points
- Nemetschek completed the acquisition of HCSS on July 1, 2026; deal value was undisclosed
- Thoma Bravo received a 28% minority stake in Nemetschek’s Build & Construct segment
- HCSS reported $215 million in 2025 revenue, ~21% ARR growth and ~40% EBITDA margin

Analysis
The HCSS deal gives Nemetschek a high‑margin, fast‑growing ARR stream that can be valued at typical construction‑software multiples of 6‑8x revenue, suggesting a potential enterprise value north of $1.3 billion for the combined segment. By integrating HCSS’s heavy‑civil data engine, Nemetschek can accelerate AI‑enabled analytics that are increasingly demanded by infrastructure owners seeking predictive maintenance and cost‑optimization. For investors, the transaction illustrates a trend of larger AEC platforms consolidating niche vertical SaaS players to broaden addressable markets and improve net‑revenue retention through bundled offerings. Operators will likely see tighter integration between design and field execution tools, reducing siloed workflows and enabling more accurate forecasting. The 28% equity position for Thoma Bravo aligns capital incentives, reducing the risk of future divestitures and supporting a longer‑term growth narrative for the Build & Construct unit.
