July 9 (Reuters) - Auto parts retailer Bapcor

rejected on Tuesday the A$1.83 billion ($1.23 billion) buyout

offer from private equity firm Bain Capital, saying the proposal

"does not represent fair value for Bapcor".

Bain Capital had offered to buy Bapcor for A$5.4 per share

in cash, representing a 23.9% premium to the stock's June 7

close of A$4.36.

Bapcor had a market value of A$1.72 billion as of Monday's

close, according to LSEG data.

Bain Capital did not immediately respond to a Reuters'

request for comment.

In a separate announcement, Bapcor named Angus McKay as its

executive chairman and chief executive officer.

The struggling automotive retailer also said its statutory

net profit after tax for the second half of the year would be

hit by impairment charges in the retail business.
