PLANCHE 00 Executive Summary — 5 Key Findings
PLANCHE 01 Scale & Market Position — The UK's Commercial Ecosystem

Tesco PLC (TSCO:LSE) is not merely a supermarket chain. It is a £69.9B revenue commercial ecosystem — a retail media network ranked joint #1 in Europe, a wholesale empire underpinning 7,000+ independent convenience stores, and a 30-year loyalty programme covering 24M+ UK households. If you are selling to UK grocery, consumer goods, retail technology, wholesale, or foodservice — you are working around Tesco whether you like it or not.

The scale is not academic. Tesco's FY2025 results (52 weeks ended 22 February 2025) confirm a business operating with the financial discipline of a company that knows it cannot coast on market position. Pre-exceptional profit growth of +10.9% YoY — on a base that is already large — is the number that matters for the investment case.

28.5% share. Up 70bps year-on-year. Sainsbury's holds ~15%. Morrisons holds ~9%. No other UK grocer is within 5 percentage points. The gap has been widening, not narrowing, for the past four years.

PLANCHE 02 Clubcard Data Flywheel — 24M Households. £6.60 ROAS. One Moat.

Clubcard is 30 years old and more dangerous than ever. With 24M+ UK households holding a Clubcard — roughly 85% of all UK homes — Tesco's first-party purchase dataset is the largest in UK retail. That data powers the Tesco Media & Insight Platform (TMI), which delivered 9,000+ campaigns in FY24/25 to 450+ brand partners, achieving a reported £6.60 ROAS on multichannel placements vs £3.80 on other platforms.

The media network has attracted the world's largest media agencies as distribution partners — GroupM, The Trade Desk, Omnicom Media Group, and LiveRamp — all paying to access Clubcard's first-party, purchase-linked, consent-granted audience data. In an era of third-party cookie deprecation, this dataset is the rarest thing in advertising.

The loyalty programme has become the primary Aldi/Lidl defence mechanism: Clubcard Prices (~8,000 weekly deals) offers discounted member pricing that discounters cannot replicate without building their own loyalty infrastructure. Tesco's own published figure: members save an average of £392/year via Clubcard Prices. That is the price of ecosystem lock-in.
