U.S. private equity firms Warburg Pincus and GTCR plan to sell healthcare services provider Sotera Health.

Sotera Health is exploring a potential sale worth as much as $5 billion including debt.

The company’s owners, Warburg Pincus and GTCR, are working with investment banks to assist them in the sales process.

Earlier this year, Sotera sold its medical isotopes business to U.S. power technology company BWX Technologies.
