Bain and Advent Team Up on a Fresh Bid for Brazil’s Amil

Economy

Key Facts

—The move. Bain Capital has teamed with fellow buyout firm Advent on a new proposal for Amil, one of Brazil’s largest health insurers, according to Estadao.

—The seller. Owner Jose Seripieri Filho is said to be open to selling a stake while keeping control.

—The asset. Amil is Brazil’s fourth-largest insurer, with about 5.4 million members, 31 hospitals and revenue near R$26 billion (US$5.0 billion).

—The history. Seripieri bought Amil from UnitedHealth in late 2023 for about R$11 billion (US$2.1 billion), most of it assumed debt.

—The catch. Its individual-plans book has been deeply loss-making, making it a turnaround play rather than a clean asset.

—The hurdles. Any deal would need clearance from the health regulator, the ANS, and the antitrust watchdog, the CADE.

Two global private-equity firms have joined forces to chase Amil, reviving foreign interest in one of Brazil’s largest but most troubled health insurers.

Bain Capital has teamed up with Advent on a fresh proposal for the insurer, according to the Broadcast column of the newspaper Estadao. Both firms circled Amil separately during its last sale, in 2023, and are now said to be working together.

The owner, Jose Seripieri Filho, is reported to be willing to sell a stake while keeping control. That stance, if it holds, points to a deal closer to a partnership than an outright takeover.

Why private equity wants Amil

Amil is a heavyweight — Brazil’s fourth-largest health operator, with roughly 5.4 million members, 31 hospitals and 28 clinics, and revenue near R$26 billion (US$5.0 billion).

It is also a fixer-upper, an insurer that has bled money for years on its individual-plans book, a segment whose pricing no longer covers rising medical costs — exactly the kind of turnaround that buyout funds are built to run.

Bain knows the terrain, having backed NotreDame Intermedica, later merged into Hapvida, before cashing out; both Bain and Advent have long tracked Brazil’s consolidating private-health market.

Such deals usually come with an operator — in Brazil’s recent health-insurance turnarounds, funds have leaned on executives like Irlau Machado Filho, who ran the Bain-backed NotreDame Intermedica, to cut costs and reset pricing.

From UnitedHealth to a new auction

Amil has changed hands before — UnitedHealth bought about 90 percent of it for US$4.9 billion in 2012, then spent years trying to leave Brazil, where its individual plans kept losing money.

The asset has deep roots — Amil was built by the late Edson Bueno, whose family later founded the diagnostics group Dasa, before UnitedHealth absorbed it in what was then one of Brazil’s biggest foreign acquisitions.

In late 2023, Seripieri, the founder of Qualicorp and an ally of President Lula, took it off UnitedHealth’s hands for about R$11 billion (US$2.1 billion). Only R$2 billion (US$390 million) of that was equity, with the rest, roughly R$9 billion (US$1.7 billion), assumed liabilities, much of it tax and litigation.

Since then he has reshaped it, including a 2025 deal that folded Amil’s hospitals into a venture with the diagnostics group Dasa. A sale of a stake to Bain and Advent would be the next step in carving value from a business bought cheaply and as-is.

The wider sector explains the interest, with Brazil’s private-health market consolidating around a few large groups while medical-cost inflation punishes standalone individual plans — the very weakness dragging on Amil, which buyers now frame as fixable rather than failing.

Nothing is settled: the terms have not been disclosed, the companies typically decline to comment on market talk, and any transaction would face scrutiny from Brazil’s health and antitrust regulators before it could close. A change of control in health insurance is especially sensitive in Brazil, where regulators guard continuity of care for millions of members.

Frequently Asked Questions

What is Amil?

Amil is one of Brazil’s largest health insurers and hospital operators, ranking fourth by market share with around 5.4 million members, 31 hospitals and 28 clinics. It earns revenue near R$26 billion (US$5.0 billion) a year, but its individual-plans business has been heavily loss-making, which has shaped every attempt to sell or restructure it.

Who is trying to buy it?

According to Estadao’s Broadcast column, the private-equity firms Bain Capital and Advent have teamed up on a new proposal. Both pursued Amil separately during its 2023 sale, and the current owner, Jose Seripieri Filho, is reported to be open to selling a stake while keeping control.

How did the current owner acquire Amil?

Jose Seripieri Filho, founder of the health-plan administrator Qualicorp, bought Amil from UnitedHealth in late 2023 for about R$11 billion (US$2.1 billion). Only R$2 billion (US$390 million) was equity, with the rest assumed liabilities, in an as-is deal that let UnitedHealth exit Brazil after years of losses.
