HF Financial Corp. (Nasdaq: HFFC) (the “Corporation”) today announced it will hold its Annual Meeting of Stockholders on December 13, 2011 (the “Annual Meeting”). The record date for the Annual Meeting is October 17, 2011. The Corporation noted that it is consulting with the Federal Reserve Board regarding the intention of PL Capital Group, an owner of approximately 9.9% of the Corporation’s outstanding shares, to nominate two directors to the Corporation’s Board of Directors. The Board of Directors, in consultation with its outside counsel, has determined that PL Capital Group’s proxy solicitation and other recent actions are in violation of the federal banking laws because PL Capital Group has failed to obtain the required prior regulatory approval under the Federal Reserve Board’s control regulations. The Board has informed PL Capital Group of this issue. Given the potentially serious implications of PL Capital Group’s actions, the Corporation has advised the Federal Reserve Board of its concerns and plans to await the Federal Reserve Board’s direction before considering PL Capital Group’s nominations.
