Books on Corporate Scandals: Enron, Theranos, WeWork and Wirecard

Corporate scandals make gripping reading because they are human stories: brilliant, persuasive people, admiring investors, loyal employees, and a slowly growing gap between what a company said and what was true. They are also practical lessons for anyone who invests, works for a company, or runs one.

The four scandals at a glance

Enron: the smartest company in America

In the late 1990s, Enron was celebrated as one of the most innovative companies in the world. It transformed itself from a pipeline operator into a trading powerhouse, and its share price soared.

Behind the headlines, executives used complex accounting and off-balance-sheet partnerships to hide debt and make results look far better than they were. When the truth began to surface in 2001, confidence collapsed within weeks. Enron filed for bankruptcy in December 2001, and its auditor, Arthur Andersen, one of the world's largest accounting firms, collapsed with it.

The scandal led directly to the Sarbanes-Oxley Act of 2002, which tightened rules on corporate financial reporting in the United States.

The Rise and Fall of America's Biggest Corporate Fraud by Cole Osborne takes you inside the story, from Kenneth Lay's vision and Jeffrey Skilling's ideas to Andrew Fastow's financial structures and the culture that rewarded appearances over reality.

Theranos: the billion-dollar lie

Elizabeth Holmes founded Theranos with a promise that captured the imagination of Silicon Valley: hundreds of laboratory tests from a single drop of blood, faster and cheaper than ever before.

Investors poured in money, and a board filled with famous names lent credibility. But the technology didn't work as claimed. After investigative reporting from 2015 exposed the problems, the company unravelled. Holmes was convicted of fraud in 2022.

What makes Theranos so troubling is that the product touched people's health. Patients received test results that couldn't be trusted.

The Theranos Fraud by Cole Osborne tells how the image of a visionary founder, glowing magazine covers and a star-studded board concealed a company that could not do what it promised.

WeWork: the $47 billion story

WeWork's business was simple: lease office space, fit it out attractively, and rent it to freelancers and companies on flexible terms. What made it extraordinary was the story its founder, Adam Neumann, told about it: a movement that would change how people work and live.

Investors believed the story, and WeWork's private valuation reached $47 billion. When the company prepared to list on the stock market in 2019, its public filings exposed heavy losses and governance concerns. The listing was abandoned, Neumann stepped down, and the valuation collapsed.

WeWork is less a tale of hidden accounting than of hype: how capital, ambition and a compelling narrative can push a valuation far beyond what the underlying business supports.

The WeWork Illusion by Cole Osborne traces how a subletting business was sold as a world-changing mission, and why nobody with the power to stop it did.

Wirecard: Europe's greatest corporate scandal

Wirecard was Germany's fintech success story: a payments company that joined the DAX index of Germany's largest companies and was, for a time, worth more than Deutsche Bank.

Much of its reported business came from partner companies in Asia and the Middle East that barely existed. Journalists who questioned the numbers were attacked, and short-sellers were investigated. In June 2020, Wirecard admitted that €1.9 billion supposedly held in trust accounts probably didn't exist. It filed for insolvency within days. Its chief executive was arrested; its chief operating officer disappeared.

Wirecard and the Missing Billions by Cole Osborne explains how the machine that hid the gap was built, and how it finally broke.

The warning signs they shared

These companies worked in different industries, countries and decades. Yet the same patterns appear again and again:

The lesson isn't that charisma or ambition is bad. It is that belief, when nobody is checking, can carry a company a very long way from the truth.

Five lessons for investors, employees and founders

1. Follow the cash, not the story. Profits on paper mean little if real cash isn't coming in.
2. Complexity is a question, not an answer. If nobody can explain how a company makes money, find out why.
3. Famous names are not due diligence. A prestigious board or investor list doesn't prove a product works.
4. Listen to credible critics. In several of these stories, journalists and analysts were right for years before anyone acted.
5. Culture shapes behaviour. Companies that reward appearances over honesty eventually get the results they reward.

The people who saw it first

Every one of these stories has people who spotted the problem early, often at great personal cost. They are some of the most inspiring figures in business history.

• Enron: in 2001, Fortune journalist Bethany McLean asked in print how Enron actually made its money. Later that year, Enron vice president Sherron Watkins warned Kenneth Lay about the company's accounting.
• Theranos: young employees, including Tyler Shultz and Erika Cheung, raised concerns about the lab's testing. Their information helped Wall Street Journal reporter John Carreyrou expose the company from 2015.
• Wirecard: Financial Times journalist Dan McCrum reported on Wirecard's accounts for years, and faced investigation himself, before the company's collapse proved him right.
• WeWork: the company's own stock-market filing in 2019 gave analysts and journalists the numbers they needed to question its valuation publicly.

The common thread: individuals willing to ask simple questions, and keep asking them.

A simple early-warning checklist

You don't need to be an accountant to notice when something seems off. Ask these questions about any company you invest in or work for:

Other scandals worth knowing about

These four are not alone. Other collapses often discussed alongside them include Bernie Madoff's investment fraud, the fall of Lehman Brothers in the 2008 financial crisis, Volkswagen's emissions-test cheating and the collapse of the cryptocurrency exchange FTX. Each adds a different angle, from outright Ponzi schemes to reckless risk and engineering deception, but the warning signs above appear again and again.

How the scandals changed the rules

• After Enron: the Sarbanes-Oxley Act made executives personally certify their financial statements and strengthened oversight of auditors in the US.
• After Theranos: renewed debate about how much scrutiny health-technology start-ups and their investors apply to scientific claims.
• After WeWork: investors became more sceptical of founder control and of valuations far ahead of the business.
• After Wirecard: Germany reformed its financial supervision and scrutiny of auditors.

Which book should you read first?

Read all four and you will have a working education in how companies fail, and in how to spot the signs earlier than the people in these stories did.

Reading these books as case studies

If you are reading for study or work, a few habits get more from each book:

• Mark the turning points. Highlight the moments where someone could have stopped the problem, in one colour.
• Note the red flags. Add a note each time a warning sign appears, then compare across books.
• Track the timeline. Search for years and dates to rebuild how quickly each collapse happened.
• Discuss them. These books work well for book clubs and team reading, because everyone draws different lessons.

In short

Enron, Theranos, WeWork and Wirecard are four very different companies with one shared story: a compelling vision, admiring backers, weak checks and a truth that eventually couldn't be hidden. Read them for the drama, and keep them for the lessons. The next scandal will look different on the surface, and much the same underneath.
