VIENNA, Feb 27 (Reuters) - Austrian Erste Group Bank <ERST.VI>, emerging Europe's No.3 lender, signed a long-expected deal to get government support on Friday but scrapped its outlook for 2009 in view of the uncertain economic environment.
The deal to raise up to 2.7 billion euro ($3.4 billion) in capital comes after talks started in October and analysts said the mounting problems in emerging Europe may already have outgrown the support provided by the capital injection.
Economists who in October expected the former Communist part of Europe to grow this year now forecast a contraction of the region's economy. Recession and currency devaluations will likely lead to a rise in bad debts and weigh on banks' capital.
"It doesn't look to me as if that's going to be the end of capital injections," said Francois Boissin, analyst at Exane BNP Paribas. "I don't see how their solvency will be sufficient."
Erste acknowledged the emerging European crisis had worsened by scrapping a forecast made in December to post a 10 percent rise in operating earnings this year, saying on Friday it was not appropriate to give guidance in the current environment.
Erste shares were up 5.4 percent at at 8.17 euros by 0830 GMT, outperforming a 2.4 percent drop in the DJ Stoxx Banking index <.SX7P>.
The structure of the deal Erste signed also differed from that announced in October, as the bank now aims to raise money from private investors as well as the government to bypass dividend restrictions that would have come with pure state aid.
The bank said the government will underwrite up to 1.9 billion euros in non-voting participation capital, a form similar to preference shares, and it hopes to raise 400 million euros from current shareholders and new investors.
If it gets as much from private investors, it will have no restrictions on dividend payments under European Union rules and will only have to pay a coupon of 8 percent on the capital.
The remainder of the total sum is expected to be raised in hybrid capital, Erste said in a statement.
Erste reiterated earnings partly released two weeks ago, saying it made a 603 million euro net loss in the fourth quarter as loan loss provisions quadrupled and as it wrote off Icelandic bank debt and emerging European goodwill.
Net interest income, the group's main revenue source, still grew by 22 percent in the fourth quarter, to 1.34 billion euros, but the increase was eaten up by loan loss provisions of 469 million euros, four times the level of a year earlier.
Erste will cut its 2008 dividend to 0.65 euro from 2007's 0.75 euro. (Reporting by Boris Groendahl; editing by John Stonestreet and Dan Lalor) ($1 = 0.7853 euro)
