Mid-market buyout firm Odyssey Private Equity has taken a 20 per cent stake in Delta Agribusiness, paving the way for the agricultural retailer to buy up rivals and open stores in its pursuit of a nationwide footprint.

Odyssey managing partner and ex-Quadrant Private Equity deal-maker George Penklis said it was unusual for private equity to invest in a rural merchandiser but the firm made an exception because Delta had "strong growth opportunities". Delta sells farm inputs such as agricultural chemicals, fertilisers and fencing materials across 28 outlets in regional NSW. It also provides advice and marketing services to farmers.
