UPDATE 2-EQT AB down 7% after Swedish finance watchdog announces probe

(Adds EQT comment, updates shares)

STOCKHOLM, Sept 24 (Reuters) - Swedish regulators will investigate EQT over a delay in publishing information, the Financial Supervisory Authority (FSA) said on Friday, sending shares in the private equity firm lower.

EQT said last week that it was in dialogue with the FSA on the handling of information about a revision of the lock-up-structure for Partners in EQT AB and the sale of shares following that revision.

“The FSA has decided to open an investigation on EQT AB on suspected breach of market abuse regulations in connection with a delayed publication of insider information,” the financial watchdog said.

EQT, whose shares were down 6.9% at 1010 GMT, said it had noted the information from the FSA, while the dialogue continued.

“EQT AB’s assessment remains that the company has handled the timing of announcing the insider information correctly,” an EQT spokesperson said in an e-mail, adding the firm had no further comment.

EQT, which has around 71 billion euros ($83.3 billion) in assets, said last week that it estimated to have handled the information accurately, and that it had obtained external expert advice on the matter involved.

It announced on Sept. 7 that it had prolonged EQT AB Partners’ IPO share lock-up period to strengthen its long-term ownership framework. EQT also said partners would sell EQT shares representing 6% of the share capital.
