Ocado has overhauled its corporate structure as it gears itself up for a summer flotation.

The retailer, which is planning an initial public offering following the general election, has registered two new companies - Ocado Holdings and Ocado Group - with Companies House, as it aligns its structure more closely with that of other major supermarkets.

"Ocado has simply created a group structure, which separates the shareholding entity from the operating entity," said a spokesman.

This week, Ocado published full-year results showing it had narrowed its operating losses to £14.4m in the 52 weeks to 29 November 2009. Sales rose 25% to £402m and EBITDA increased to £9.2m from £2.2m in 2008.

Ocado also revealed it had formed a new partnership with customer insight company 5one, which would allow its suppliers to accurately analyse shopper behaviour and better target promotions.

5one's web portal will cover every SKU sold by Ocado over every day for the past 30 months and allow suppliers to view data from a category summary level right down to the micro-level of individual products.

Users can access promotional metrics, regional performance figures, basket profiles and product launch details.
