Hubris

Exaggerated pride or self-confidence in decision-makers, particularly CEOs, causing them to overestimate their ability to add value and overpay for acquisitions, as identified by researchers Hayward and Hambrick.

THE IDEA

1. Hubris

It is an unwritten law of the stock market that corporations must keep growing, year after year, and for the executives of a company straining to meet these growth expectations, buying another company can look like an awfully attractive shortcut. But it’s an expensive shortcut. The source reports an average acquisition premium for public companies of 41%, which means that if the target company is valued by the stock market at $100 million, the acquirer will bid $141 million for it. Or, to translate that into human terms, the acquiring CEO is basically saying to the target CEO, “I can run your company at least 41% better than you can.”

As you might imagine, this self-confidence often proves unwarranted. Warren Buffett said, “In the past, I’ve observed that many acquisition-hungry managers were apparently mesmerized by their childhood reading of the story about the frog-kissing princess. Remembering her success, they pay dearly for the right to kiss corporate toads, expecting wondrous transfigurations.” Unfortunately, said Buffett, “We’ve observed many kisses but very few miracles.”

Two business-school professors, Mathew Hayward and Donald Hambrick, were puzzled by this phenomenon. Why do CEOs keep making pricey acquisitions that rarely pay off? The answer, they suspected, might have more to do with human flaws than with financial miscalculations. They theorized that the acquiring CEOs were being led astray by their own hubris.

Hubris is exaggerated pride or self-confidence that often results in a comeuppance. In Greek mythology, a hubristic protagonist often suffers humiliation. When Icarus ignored advice not to fly too close to the sun, his wax wings melted and he fell to his death. (By contrast, in American business, hubris is less damning. If Icarus had been a bank CEO, he’d have escaped with a $10 million golden parachute.)

Hayward and Hambrick speculated that executives’ hubris—their confidence that they could work magic with their acquisitions—would lead them to overpay for their targets. The researchers tested this theory by analyzing every large acquisition ($100 million or more) conducted in the public markets during a two-year period, a sample that contained 106 transactions. They examined whether the price paid was associated with three factors that might inflate the acquiring CEO’s ego. The excerpt ends before identifying those factors or reporting the results.

When to use it

  • An executive team evaluating a large acquisition target, questioning whether the proposed premium is justified by synergy or inflated by CEO confidence.

  • A startup founder ignoring negative market feedback on a new product, believing their vision cannot fail based on past successes.

  • A hiring manager trusts their own ability to spot talent so completely that they dismiss contradictory interview evidence and reference checks.

FROM THEORY TO EVERYDAY LIFE

In practice

01

The Overpriced Acquisition

A CEO pays a 41% premium to acquire a target company, convinced their superior management skills can generate returns that justify the steep price, ignoring historical data showing that most such acquisitions fail to deliver value for the acquirer.

02

Icarus in the Boardroom

A company's board lavishes praise on the CEO for a series of successful small bets. Emboldened by this glory, the CEO pursues a massive, transformational deal that stretches the company's resources, confident that past success guarantees future results, a classic sign of hubris as described in the text.

A MOMENT TO REFLECT

Put it to work.

  1. In your own experience, when has confidence crossed the line into hubris, leading to a costly mistake?

  2. What organizational safeguards can be put in place to challenge a leader's overconfident vision or acquisition strategy?

  3. How can a leader distinguish between the necessary optimism to inspire a team and the dangerous hubris that blinds them to risks?
