Wirecard: How Due Diligence Missed a €1.9 Billion Hole

Wirecard was once one of Germany's most celebrated technology companies. The payments processor joined the DAX, Germany's leading stock index, in 2018, replacing Commerzbank. Less than two years later, in June 2020, it admitted that €1.9 billion of cash supposedly held in trust accounts in Asia probably did not exist. Within days, it filed for insolvency.

Wirecard is one of the largest corporate frauds in European history, and one of the most instructive for investors. Auditors, regulators, analysts and many investors missed warning signs that journalists and short sellers had raised for years. This post-mortem explains what happened and what it teaches about due diligence.

1. The Business

Wirecard processed card payments for merchants and offered related banking services. Much of its reported profit came from Asian operations run through third-party acquiring partners, businesses that processed transactions on Wirecard's behalf. Revenue and profits from these partners were difficult for outsiders to verify.

2. The Warning Signs

• Persistent allegations. Short sellers and analysts raised questions about Wirecard's accounting for years.
• Investigative journalism. The Financial Times published a series of reports from 2019 alleging accounting irregularities in Wirecard's Asian operations.
• Opaque third-party partners. A large share of profits came from partners with little visible substance.
• Cash that could not be seen. Large sums were reportedly held in escrow accounts rather than on Wirecard's own balance sheet.
• A special audit. A KPMG special audit completed in 2020 said it could not verify key parts of the business.

3. How Oversight Failed

• The auditor. EY signed off on Wirecard's accounts for years and later faced intense criticism over whether it properly verified the cash balances.
• The regulator. Germany's financial regulator, BaFin, banned short selling of Wirecard shares in 2019 and filed criminal complaints against journalists and short sellers, rather than focusing on the company itself.
• Investors and analysts often accepted management explanations and the credibility that came with index membership.

4. The Collapse

• In June 2020, Wirecard announced that the €1.9 billion probably did not exist, and filed for insolvency shortly after.
• Former CEO Markus Braun was arrested, and a long criminal trial followed.
• Former COO Jan Marsalek disappeared and became an internationally wanted fugitive.
• The scandal led to reforms of German financial supervision and audit oversight.

5. Lessons for Due Diligence

• Verify cash independently. Confirm balances directly with banks, not only through intermediaries or management.
• Follow the profits. Scrutinise revenue that depends on opaque third parties. See revenue recognition mistakes.
• Take critics seriously. Short sellers and investigative journalists can surface real problems.
• Do not outsource judgement. Index membership, audit opinions and regulatory approval are not guarantees.
• Watch for defensive behaviour that targets critics rather than answering their questions.

These lessons apply equally to private companies. See operational due diligence and due diligence red flags.

Frequently Asked Questions

What was the €1.9 billion?

Cash that Wirecard said was held in trust accounts in Asia. In June 2020 the company admitted it probably did not exist.

Why did the auditor not catch it?

This has been the subject of intense scrutiny. Critics argue the auditor relied too heavily on documents from third parties rather than confirming balances directly.

What role did the regulator play?

BaFin banned short selling of Wirecard in 2019 and pursued journalists and short sellers, decisions that were widely criticised after the collapse.

What happened to Wirecard's executives?

The former CEO was arrested and tried; the former COO fled and remains a fugitive.

The Bottom Line

Wirecard's collapse showed that audits, regulators and index membership can all fail. For investors, the enduring lesson is to verify independently, follow where profits and cash really come from, and treat credible criticism as a reason to dig deeper rather than dismiss it.
