What Intertek does
Intertek Group plc is a UK-headquartered, London Stock Exchange-listed (LSE: ITRK) Total Quality Assurance company operating 1,000+ laboratories and offices across 100+ countries with a workforce of approximately 35,000 people. The company's heritage traces to 1896 (Electrical Testing Laboratories), and it was rebranded and listed as Intertek Group plc in 2002. Intertek provides integrated Assurance, Testing, Inspection, and Certification (ATIC) services under its "Total Quality Assurance" platform, complemented by Auditing, Consulting, People Assurance, Training, Sourcing, and Business Assurance offerings. The business is organized into two reporting divisions: Testing & Assurance (approximately £1,844.4m revenue, 25.0% operating margin in 2025) covering consumer products, retail, food, healthcare, and chemicals; and Energy & Infrastructure (approximately £1,587.2m revenue, 10.0% operating margin) covering solar, wind, oil and gas, power, and construction.
The company serves enterprise and SMB clients across multiple verticals including Products & Retail (over one-third of global retailers' supply chains), Energy & Commodities, Food & Healthcare, Construction & Engineering, Transportation, and Chemicals. Revenue is generated through per-test fees, project-based testing contracts, recurring certification subscriptions, and multi-year enterprise agreements. Proprietary platforms include InterLink™ (data management), SupplyTek (supply chain market access), Intertek AI² (AI assurance), Protek (health, safety, wellbeing assurance), SATELLITE™ (client test program), and Inlight™ (supply chain intelligence). Recognized certification marks (ETL Listed, Tick Mark, BEAB Care, G Mark, S Mark, GS Mark, Warnock Hersey) are accepted by Authorities Having Jurisdiction globally, forming a core part of the value proposition.
Recent strategic developments include a £9.3 billion take-private acquisition by EQT AB (announced June 2026, backed by ADIA and Mubadala sovereign wealth funds), a strategic review to separate into two specialist businesses by mid-2027, and multiple bolt-on acquisitions in 2025–2026 spanning drone-based solar inspection (AePVI), US flooring testing (PTL), Costa Rica food/medical testing (Suplilab), and India's solar PV lab (Mitsui). Distribution combines global direct enterprise sales, regional channel partners, and self-serve client portals (i2Q, iCare, iEnable, Global Market Access, My TestCentral).
