Pathology giant Healius, capitalised at $1.17 billion, has agreed to sell its Lumus radiology business to pan-Asian buyout group Affinity Equity Partners in what’s expected to be one of the largest healthcare corporate carve-outs in Australian M&A history.

Street Talk can reveal that Affinity Equity Partners, advised by Allier Capital and Gilbert + Tobin, will acquire Lumus for a price north of $900 million in the UBS-run auction. Affinity dealmaker Mark Chudek is running point on the deal, and an announcement will be made on the Australian Securities Exchange on Monday.
