The New Zealand Shareholders' Association will vote against the $434 million sale of PGG Wrightson's seeds division to a Danish cooperative.
The retail investor lobby says the mostly cash offer from DLF Seeds is attractive at face value, with a $292m capital return attached. However, that short-term gain will shrink Wrightson to less than half its current size and leave it holding businesses inferior to the grains and seeds division.
"It seems to us that if shareholders accept DLF's offer, they will potentially lose in the long run unless PGW can pull a rabbit out of the hat and grow the rump business," the Shareholders' Association said.
The investor lobby group will vote its proxies against the resolution at next week's combined annual and special meeting. It said raising capital to fund organic growth was an obvious alternative to selling its most valuable business.
Agria Corp took control of Wrightson in 2011, having taken a cornerstone shareholding in 2009 to recapitalise the rural services firm in the aborted merger with Silver Fern Farms.
