Retail players, trends, and how to crack retail cases

The main retailers by region, the trends of 2024 to 2026, regulation basics, and the typical retail case prompts with the first driver to check.

Industry brief, with a one-minute summary: Retail

Firm processes and online tests change from year to year and differ by office. Use this to prepare, and confirm the exact current steps on the firm's own careers page.

Key takeaways

  • Common traps in retail cases: Praising total sales growth without asking for like-for-like growth.
  • Own brands keep gaining in Europe.
  • Retail theft became a board topic.
  • Cheap cross-border parcels face new duties. The US suspended its USD 800 duty-free threshold (de minimis) for all countries on 29 August 2025.

Key idea

Retail is local. The winning formats and players differ by country, so start every retail case by asking which format, which country, and whether the problem is in the stores the client already has or in its growth plan.

AfricaShoprite, plus many local chains and informal shopsShoprite reported revenue of about ZAR 257 billion and a net 281 new stores in the year to June 2025

So-what

Discounters and local champions win in many markets. A global name does not guarantee success in a new country.

Trends from 2024 to 2026 (checked September 2026)

  • Own brands keep gaining in Europe. NielsenIQ data published by PLMA show private label at about 38.7 percent of grocery value across 17 European countries in the year to week 40 of 2025, slightly up on 2024. Discounters such as Aldi and Lidl sell mostly own brands.
  • Retail theft became a board topic. In England and Wales, police-recorded shoplifting rose for several years, then fell 4 percent to about 507,000 offences in the year to March 2026, according to the ONS. Retailers still spend more on security tags, cameras, and staff.
  • Cheap cross-border parcels face new duties. The US suspended its USD 800 duty-free threshold (de minimis) for all countries on 29 August 2025. In November 2025 EU governments agreed to remove the EU's EUR 150 customs duty exemption in 2026, with a simple temporary way of charging duty on small parcels until a permanent system is ready, planned for 2028. Both changes help store-based apparel and home retailers compete with ultra-low-price online sellers.
  • In India, fast-growing quick commerce apps compete with supermarkets and small shops for top-up grocery shopping. The E-commerce and quick commerce module covers this.
Regulation basics (general, check the country)

Retailers need licences to trade and to sell some goods (alcohol, tobacco, medicines). Planning (zoning) rules can limit large out-of-town stores. Some countries limit opening hours, for example Sunday trading rules in parts of Europe. Food safety, price labelling, and consumer rights on returns apply almost everywhere. Some countries limit foreign ownership of retailers; India, for example, restricts foreign investment in multi-brand retail. In the EU, rules on unfair trading practices limit how large grocers can treat smaller food suppliers. Competition authorities also review mergers between large grocers.

Typical retail case prompts and how to crack them

A supermarket chain in Poland has falling profitsProfitabilityRevenue (stores x LFL sales) and costs (margin, shrink, staff, rent)Like-for-like sales, then gross margin by category

So-what

In most retail cases the first number to ask for is like-for-like sales or the economics of a single store.

For the full method behind these prompts, see the Profitability, Market expansion, and Declining industry and turnaround case-type modules. Retail also shows up inside Guesstimates and market sizing (how many supermarkets does Riyadh need?) and in Mergers, acquisitions, and due diligence (should a private equity fund buy this chain?).

Timed math drill

A grocer plans a new store in Riyadh. Fit-out and opening stock cost SAR 12 million. Once mature, the store earns a contribution of SAR 3 million a year. Ignoring the ramp-up year, what is the simple payback in years?

Common traps in retail cases

Praising total sales growth without asking for like-for-like growth. Treating a price increase in the basket as volume growth. Forgetting that new stores near old ones take sales from them (cannibalization). Comparing gross margins across formats. Ignoring shrink and markdowns because they are not a separate line in the summary P&L. Assuming a format that works in one country will work in another.

Check your understanding

A chain's profit fell. Like-for-like sales are flat and gross margin fell 2 points. Where do you look next?

Check your understanding

What does sales per square metre tell you?

Check your understanding

Why might the end of duty-free treatment for low-value parcels in the US and the EU help store-based fashion retailers?
