ISS Q1 Organic Growth of 7.4% Beats Estimates; Goldman Maintains Buy Rating

Overview

This report is Goldman Sachs' review of Danish facility services company ISS's Q1 2026 results. ISS achieved 7.4% organic growth, significantly exceeding market consensus (5.4%) and Goldman's estimate (6.3%), driven by stable pricing power and strong above-baseline business contribution. Based on this strong start, Goldman sees upside potential to the full-year organic growth guidance (>5%) and reiterates its Buy rating with DKK 275 target price. Additionally, ISS announced the acquisition of minority stake in ISS Turkey and expects resolution of Deutsche Telekom arbitration in H1.

Core views

Key Views: Strong Q1 performance supports full-year upside potential Demand & Growth Quality: ISS's Q1 organic growth of 7.4% (vs 4.3% in Q4) exceeded consensus by 200bps. Growth drivers: pricing contribution ~+4% (flat QoQ); like-for-like volume ~+1% (vs ~+1.5% in Q4); net new contracts ~+1% (improved from 0.5% in Q4); project & above-baseline work ~+1.5% (vs -2% in Q4). While above-baseline business is typically lower-quality growth, combined with stable pricing and improving new contracts, the overall growth structure remains healthy. Full-Year Guidance & Outlook: Management reaffirmed FY26 guidance: (1) organic growth >5% (including LFL volume >1% and net new >1%); (2) operating margin >5% (ex-IAS 29); (3) reported free cash flow >DKK 2.5bn. Notably, FX headwind narrowed to -1.5% from -2%, providing additional buffer. Goldman sees potential to exceed consensus (5.5%-6.0%). Capital Allocation & Key Events: On May 1, ISS announced acquisition of Actera's 40% stake in ISS Turkey at 5-6x EV/EBITA. Payment includes $100m cash in 2026, with deferred payments capped at $18m annually over three years. ISS Turkey has been fully consolidated with 25% revenue CAGR 2021-2025; transaction expected to increase FY26 leverage by ~0.1x. Deutsche Telekom arbitration resolution still expected in H1 2026. Valuation Rationale: Goldman's 12-month target price is DKK 275, using blended valuation: 85% fundamental (11.5x 2027E EV/EBITA) + 15% M&A theoretical (10x 2027E EV/EBITDA based on historical transactions). Investment thesis highlights that despite recent re-rating, ISS can return ~50% of market cap over five years, making it one of Europe's most attractive stocks for buyback potential.

Analysis framework

Institutional Analysis: Volume-Price Breakdown Validates Growth Quality + Blended Valuation Anchors Target Price Goldman employs a typical service industry 'volume-price breakdown' to assess growth quality. Unlike focusing solely on total revenue growth, organic growth is decomposed into pricing, LFL volume, new contracts, and above-baseline projects to distinguish sustainable core expansion from temporary factors. For valuation, given ISS's profile as a mature facility services company with both stable operations and M&A potential, Goldman uses a blended '85% fundamental + 15% M&A theoretical' model, reflecting both DCF logic and industry consolidation premium. This approach helps investors differentiate short-term fluctuations from long-term value drivers.

Methodology notes

• Industry Analysis FrameworkVolume-Price Breakdown

  Decomposing organic growth into pricing, like-for-like volume, new contracts, and special project contributions

  For B2B contract-based industries like facility services, growth numbers alone may mask structural issues. Volume-price breakdown identifies whether growth stems from price increases (short-term benefit but unsustainable), existing client optimization (high quality), or new orders (future sustainability indicator), enabling more accurate assessment of earnings beat quality.

• Valuation methodsEV/EBITDA valuation

  Using EV/EBITDA multiples for fundamental and M&A theoretical valuation

  Facility services is capital-intensive with high depreciation/amortization, making net income susceptible to accounting policies. EV/EBITDA eliminates capital structure and tax effects, better reflecting core operating cash flow generation, serving as the key anchor for cross-company comparisons and M&A pricing in this industry.

• Valuation methodsSOTP Segment Valuation

  Blended valuation: 85% fundamental + 15% M&A theoretical weighting

  When a company has both stable organic growth and clear industry consolidation/acquisition potential, single valuation methods may distort. SOTP or blended approaches allow separate valuation of 'standalone operations' and 'M&A target' scenarios, weighted by probability or strategic importance, to more comprehensively capture potential returns.

Impact & implications

The report argues that ISS's Q1 outperformance not only validates pricing power and operational resilience but, more importantly, builds confidence in full-year delivery. For investors, this suggests ISS can continue offering certainty premium amid macro uncertainty. While acquiring ISS Turkey's minority stake slightly increases leverage, it secures full control of a high-growth asset, benefiting long-term profit realization. Deutsche Telekom arbitration resolution in H1 would remove a major valuation overhang, combined with strong buyback potential, further reinforcing the risk-reward asymmetry under the Buy thesis.

Risks

• Margin improvement slower than expected
• Unfavorable Deutsche Telekom arbitration outcome
• Free cash flow below expectations
• Organic growth slower than expected
• Operational execution risk
• M&A integration and execution risk

What to watch

• H1 2026 final outcome of Deutsche Telekom arbitration
• Whether full-year organic growth continues exceeding >5% guidance
• Post-acquisition integration of ISS Turkey and leverage ratio changes
• Sustainability of H2 new contract wins and pricing trends
