Austria's Raiffeisen plans bid for Vienna-listed Addiko

April 8 (Reuters) - Austria's Raiffeisen Bank International RBIV.VI said on Wednesday it plans to acquire smaller Vienna-listed lender Addiko ADKO.VI for 23.05 euros ($26.88) per share.

• RBI said it would make an offer for all outstanding shares of Addiko, in a deal valued at 444.6 million euros, based on Reuters calculations

• The offer price represents a discount of over 11% to Addiko's closing price of 26 euros on Wednesday

• Addiko said on Thursday RBI had not been in touch with the company before the day of the announcement of the intention to launch a takeover offer

• Addiko added it will make a statement after RBI publishes the offer document

• Once submitted, the acceptance period for the offer will run for 10 weeks, RBI said

• Following completion, the transaction would have a negative impact of about 45 basis points on RBI's common equity tier 1 ratio, excluding Russia

• RBI has a market capitalisation of $15.3 billion, compared with Addiko's valuation of $587.8 million

• The move follows another deal where RBI last month agreed to buy Istanbul-listed Garanti BBVA's GARAN.IS Romanian business for 591 million euros ($689.40 million)
