The placement to institutional investors is underwritten by Forsyth Barr and UBS New Zealand at a price of $8.50 a share.
Ebos's last major acquisition was at the end of 2011 when it branched out into veterinary products with a $105 million purchase of Masterpet. It's tacked on 18 new businesses in the past decade, including the PRNZ unit it bought from Zuellig in 2007 for $86 million.
The company told shareholders last year it was still keen on more acquisitions, and Waller told BusinessDesk in January the company was looking in the animal and human health sectors.
Symbion is Australia's leading pharmaceutical wholesaler and distributor by revenue, with annual sales of A$3.9 billion. Zuellig owns healthcare, agri-business and agricultural equipment firms across the Asia-Pacific.
The transaction is expected to grow Ebos's pro-forma sales to $6.28 billion in the 12 months ended June 30 from $1.43 billion last year, with earnings before interest, tax, depreciation and amortisation of $198.8 million and profit of $91.7 million. The company expects to post first-half sales of $3.12 billion in the six months ended Dec. 31, with net profit of $48.7 million.
The transaction is expected to settle in early July.
In an independent adviser's report, Northington Partners said the $865 million cash and scrip purchase price was about 15 per cent below the mid-point of its valuation range, and the terms and conditions were fair to shareholders not associated with Zuellig.
The report expected Ebos will achieve improved earnings from the acquisition, achieving a market-leading position for the group in Australasia, though will likely result in ceding control to Zuellig
"On balance, we conclude that the transaction is likely to be beneficial for existing Ebos shareholders," the report said.
