Two private-equity firms are reportedly teaming up with buy-out house KKR in its bid for US food group Del Monte Foods.

Vester Capital Partners and a fund run by a partner at Centerview Partners are joining KKR’s reported move for Del Monte, Reuters and Bloomberg have reported.

According to Bloomberg, Vestar and the Centerview fund, which is run by former Gillette CEO James Kilts, would make “significantly smaller” equity investments in Del Monte than KKR.

A deal could be announced in days, a source told Reuters.

Last week, Centerview announced the acquisition of US pizza manufacturer Richelieu Foods.
