PwC Faces Fresh Audit Scrutiny as WH Smith’s Accounting Crisis Deepens

Britain’s accounting watchdog has launched an investigation into PricewaterhouseCoopers’ audit of WH Smith for the year ended August 2024, widening the fallout from the retailer’s accounting problems. The Financial Reporting Council did not specify the exact focus of the probe, but the timing is significant. WH Smith has already been under investigation by the Financial Conduct Authority over potential breaches of listing and disclosure rules, after the company uncovered inflated earnings in its North American business. PwC, which has audited WH Smith since 2015, said it would fully cooperate with the regulator, while WH Smith declined to comment.

The investigation matters because WH Smith’s accounting issue was not a minor internal correction. In 2025, the company said a review had found an overstatement of around £30 million in expected headline trading profit, mainly linked to supplier income in North America being booked too early. That forced a sharp cut to the profit outlook for the division, which had previously been seen as one of the retailer’s most important growth engines. The market reaction was severe, with shares falling heavily when the problem first emerged, showing that investors were not only reacting to lower profit expectations but also to doubts about internal controls and financial discipline.

The problem also arrived at a difficult point in WH Smith’s wider business transformation. The company had been moving away from its traditional UK high street identity and repositioning itself as a travel-focused retailer, with stores in airports, train stations, and other travel locations. That strategy depends heavily on passenger traffic, discretionary spending, and confidence that international expansion can generate reliable returns. Once accounting problems appeared in North America, the investment case became less straightforward. Investors were no longer just asking whether travel retail demand would recover, but whether management had enough visibility and control over the business it was trying to scale.

The pressure intensified further in 2026 when WH Smith warned that the Iran war was weighing on global travel, passenger numbers, and spending patterns. The company suspended its dividend and reduced its full-year profit forecast, adding operational stress to an already damaged governance story. For shareholders, this combination is uncomfortable: accounting concerns weaken trust in reported numbers, while softer travel demand weakens the earnings outlook. Even if the audit investigation does not immediately prove wrongdoing, the existence of overlapping regulatory scrutiny can raise the company’s cost of capital, limit investor patience, and make any turnaround plan harder to sell.

For PwC, the case adds to a broader debate about audit quality in the UK market. Large audit firms are expected to challenge management assumptions, test revenue recognition, and identify weaknesses before they become public-market problems. The FRC is also separately examining PwC’s audit of Digital 9 Infrastructure, meaning the WH Smith probe will be watched not only as a company-specific issue but also as part of a wider discussion about auditor accountability. The central question is no longer just whether WH Smith can repair its North American business. It is whether investors can regain confidence that the company’s numbers, controls, and external audit process are strong enough to support its next phase.
