Nemetschek's 15.7% H1 Growth: Organic 2026 Outlook Confirmed, Reported View Expanded by HCSS

The guidance update was about reporting scope, not a faster organic target

The main point is straightforward: Nemetschek did not tell investors the core business just got a faster 2026 target. It fully confirmed the organic 2026 outlook, while the reported outlook was expanded following the acquisition of HCSS after HCSS was legally closed on 1 July 2026. After back-to-back guidance confirmations, the market is being asked to price a high-quality organic base first, and the added scale from HCSS second.

What the guidance math means

The core business still looks disciplined. Nemetschek delivered 15.7% constant-currency H1 revenue growth, and recurring revenues were 95.1% of mix, with subscription and SaaS representing up to 95% of group revenues. That mix matters because more of the revenue stream is predictable and recurring rather than dependent on one-off license transactions.

Bulls will argue that quality plus HCSS creates a better setup than the market is crediting. Bears will counter that the bar was raised on reported growth, not on the legacy business itself. The key test from here is simple: can HCSS support reported momentum while the organic base still holds its guide?

Recurring revenue and cash flow are the strength of the model

Nemetschek is no longer primarily selling one-off software licenses. It is selling ongoing access. In H1, subscription/SaaS revenue reached €514.7M, growing 32.4% at constant currency, while ARR climbed to €1.25B. That matters because a larger ARR base improves visibility into future quarters, supports cash generation, and makes the business less dependent on any single quarter's upside.

The profit engine also looks healthy. Nemetschek generated H1 EBITDA of €197.0M with a 30.7% EBITDA margin, while free cash flow before M&A totaled €168.2M. For a company funding AI development, product integration, and selective deals, that cash conversion matters. It shows the core business is not just growing in revenue terms; it is generating cash that can be reinvested.

Q2 was still solid, but consistency is the next test

The issue in Q2 was not weakness at the margins. It was consistency. In Q1, Nemetschek posted 17.0% revenue growth and a 31.4% EBITDA margin. In Q2, revenue growth slowed to 14.5% on a currency-adjusted basis, and the reported EBITDA margin came in at 30.1%. That still looks healthy in isolation, but for a compounding-style story, the trend matters.

After adjusting for acquisition-related one-off costs, Q2 EBITDA margin was 31.0%. That softens the bearish read. The slowdown was real, but it looks more like moderation than a breakdown in demand or pricing power.

AI and HCSS are the real proof points from here

This is where the organic-versus-reported distinction matters again. The core business held its guide. What now has to prove itself is whether AI helps strengthen the subscription engine and whether HCSS integrates without disrupting the operating rhythm.

On AI, management highlighted Bluebeam Max and broader AI rollout across the portfolio. The business logic is straightforward: if AI makes tools more useful inside customer workflows, retention and monetization can improve.

On HCSS, the risk is more operational. Integration can stretch sales teams, delay cross-sells, or make the first full quarter of contribution harder to read. That is why the next few quarters matter. Investors do not need heroic numbers. They need evidence that the new pieces are fitting together without slowing the main engine.
