June 6 (Reuters) - Fast Private Proxy advisory firm ISS on Friday urged shareholders of casino operator Penn Entertainment to elect all three nominees of hedge fund HG Vora to its board ahead of its June 17 annual meeting.
"The company is facing sustained challenges, which have resulted in total shareholder return and operational underperformance," ISS said in a note.
Penn did not immediately respond to a request for comment.
HG Vora said in April that it planned to push ahead with a proxy fight at Penn to try and elect all three of its director candidates after the casino operator said it would appoint only two of them to its board.
