The Quick Take

• Addnode Group (FRA:AR7) EBITDA surged 68% in Q3 2026, driven by efficiency improvements and software subscription growth across its engineering and architecture software segments.
• Vitec Software Group (STU:7VS) posted 15% sales and EBITDA growth; Roko AB (FRA:N8Q) delivered 44% sales growth with 57% EBITDA growth, continuing the Nordic vertical software sector's exceptional earnings quality record.
• Grupo Rotoplas (MEX:AGUA), a Latin American water infrastructure company, added 10% sales growth and EBITDA improvement, reinforcing the water infrastructure and sustainability infrastructure investment thesis.

Nordic vertical software companies and a Latin American water infrastructure operator delivered strong Q3 2026 earnings beats, reflecting the durable earnings quality characteristics that have made this cohort a favourite of quality-growth institutional investors globally. Addnode Group, which serves architecture, engineering, and design markets with software solutions, reported a 68% EBITDA surge from efficiency improvements and subscription revenue growth — a signal that the company's transition toward recurring SaaS-model revenue is creating meaningful operating leverage. Vitec Software, a niche vertical software consolidator operating the serial acquirer model in Scandinavian and European industrial markets, grew sales and EBITDA 15% as its acquisition pipeline continues to generate consistent compounding returns.

Roko AB's 44% sales growth with 57% EBITDA growth represents the most striking result in this cluster, as the spread between revenue growth and EBITDA growth demonstrates positive operating leverage — a pattern that typically leads to analyst estimate upgrades and re-rating of the quality premium applied to the company's valuation. Nordic vertical software companies are closely studied by global investors because they consistently achieve high EBITDA margins (40-60%), recurring revenue ratios above 70%, and return on equity above 20% across full business cycles — characteristics associated with dominant niche market positions with high switching costs and pricing power. Grupo Rotoplas, Mexico's leading water storage and management infrastructure company, adds an emerging market infrastructure dimension: 10% sales growth in a water infrastructure company reflects genuine end-market demand rather than easy comparable base effects.

Forward signals across this earnings cluster point to sustained Nordic vertical software performance as the primary investment theme. Addnode's next acquisition announcement will reveal whether the 68% EBITDA surge is being used to fund balance sheet re-investment or returned to shareholders. Vitec Software's pipeline commentary will indicate whether the deal flow for its niche vertical acquisition model remains robust in the current interest rate environment. Grupo Rotoplas's Mexican domestic water infrastructure market is a structural growth story driven by urbanisation, water stress, and government infrastructure investment — watching management commentary on public sector contract pipeline will indicate whether the 10% growth rate can be sustained or accelerated.
