WH Smith overstated North America profits by £30M — and £600M in market value vanished
WH Smith logged supplier income too early in its North America accounts, overstating profit by £30M and wiping almost £600M off its market cap in a single day.

What happened
In August 2025, WH Smith, the 233-year-old British retailer that had just sold its high street division to focus on travel retail, discovered an accounting error in its North American arm. The mistake was in how it calculated supplier income — rebates and marketing payments from brands — which had been logged too early, overstating trading profits.
The company cut its North America profit forecast from £55M to £25M and lowered its group pre-tax profit outlook to around £110M, well below market expectations of £140M. Shares plunged 42% in a single day, wiping almost £600M off the company's market value. The board commissioned Deloitte to conduct an independent review.
The error was a severe blow to WH Smith's fresh start. It had just sold its struggling UK high street business to focus on airport and travel retail, where it operates over 320 stores across the US. Analysts called the blunder a 'huge embarrassment' and a 'disaster' that tarnished the company's relaunch.
Why it happened
- Supplier income recognition was handled without enough controls to catch the timing error before the figures were published and relied on by the market.
- The company had just restructured around its North American growth story, so a profit miss in that division undermined the entire investment case.
- WH Smith commissioned Deloitte only after the error was discovered, meaning the inflated figures had already driven investor decisions for at least one reporting cycle.
The lesson
An accounting error in the division that is the growth story is not a bookkeeping problem — it's a strategy problem. A company that bet everything on one region cannot get that region's numbers wrong.
Aftermath
WH Smith cut its profit forecast, launched a Deloitte review, and saw its share price fall 42% in a single day. The error undermined investor confidence in the company's transition from high street to travel retail.
