May 11 (Reuters) - Activist investor PrimeStone Capital on Monday urged Intertek's ITRK.L board to "engage constructively" with EQT EQTAB.ST, after the British company rejected a third sweetened takeover proposal from the Swedish private equity firm.
PrimeStone also urged Intertek to provide supervised due diligence access and take a more realistic approach when assessing the company's fair value in a public letter.
