One of private equity’s biggest names just walked away from a software company it bought for $6.4 billion — a stark lesson in how debt-fuelled buyouts can unravel.

By the numbers

Private-equity firm Thoma Bravo has surrendered Medallia, a customer-experience software company, to its lenders — who are injecting $150 million of new capital to steady the business. For Thoma Bravo, the retreat represents a loss of roughly $5.1 billion. The firm had taken Medallia private in 2021 in a deal that valued the company at $6.4 billion, paying $34 a share in cash at the height of a software-buyout boom.

How a leveraged buyout works — and how it breaks

In a leveraged buyout, a private-equity firm buys a company using mostly borrowed money, then loads that debt onto the business it has just acquired. The plan is to sharpen the company — cutting costs, bolting on acquisitions, accelerating growth — and then sell it or float it on the stock market for a profit several years later. Used well, the borrowing acts as a lever: because the firm puts down only a fraction of the price in its own cash, even a modest rise in the company’s value can translate into an outsized return.

The catch is that the lever cuts both ways. The acquired company must generate enough cash to keep up the interest payments on all that debt. If growth disappoints, or if interest rates rise and make the debt more expensive to service, the borrowing turns from a lever into a millstone. When a company can no longer support its debt, the lenders can step in and take ownership — and the original equity owner is wiped out. That is exactly what has happened here: the lenders take the keys, Thoma Bravo absorbs the loss, and the $150 million injection is meant to stabilise the company the creditors now control.

Why this one broke

Medallia was bought in 2021, near the peak of a frenzy for software companies, when valuations were rich and borrowing was historically cheap. The years since have been unkind to exactly that combination. Interest rates climbed sharply, making the debt piled onto these businesses far costlier to carry, while growth at many software firms cooled from its pandemic-era highs. A purchase price that looked defensible in 2021 became very hard to justify — and very hard to refinance — by 2026.

In a leveraged buyout, debt is the engine — and when the engine stalls, it is the lenders, not the dealmakers, who end up with the keys.

Why it matters

The Medallia retreat is a warning sign for the broader wave of software buyouts struck in 2020 and 2021, and it may not be the last big name handed back to its creditors. It matters well beyond Wall Street, too. Pension funds, university endowments and other everyday savers invest heavily in private-equity funds, so multibillion-dollar losses ultimately ripple back to ordinary people. And it is a vivid, concrete reminder of a rule that applies just as much to households as to buyout barons: borrowed money magnifies both the gains and the losses.

What to watch

Keep an eye on how many other highly indebted software companies from the 2021 vintage run into the same wall as their debt comes due. Watch, too, for the growing role of private-credit lenders — the funds that increasingly provide this debt and, as in Medallia’s case, can end up owning the businesses outright when things sour.

Key takeaways

• Thoma Bravo handed Medallia to its lenders, booking a loss of about $5.1 billion on its 2021 $6.4 billion buyout.
• The lenders are injecting $150 million to steady the company they now control.
• It is a textbook case of how cheap-debt-era buyouts are straining now that interest rates are high.
