• Marine contractor Cal Dive International Inc., Houston, (NYSE: DVR) plans to repurchase a 12.6% stake in the company from majority shareholder Helix Energy Solutions Group Inc., Houston, (NYSE: HLX) for $86 million. Cal Dive will acquire 13,564,669 shares of the company’s common stock at $6.34 per share, representing an approximate 2% discount to the 30-day average price as of Jan. 16.
The repurchase will reduce Helix’s ownership interest in Cal Dive from approximately 57% to 51%. It will pay for the purchase with borrowings under its $300-million revolving credit facility. Cal Dive president and chief executive Quinn Hébert says the repurchase is attractive at current trading prices and that following the transaction the company will continue to have financial flexibility and liquidity through cash on hand and remaining borrowing capacity to fund operating needs. Cal Dive currently has no borrowings against the credit facility. The move represents another step in the company’s previously announced strategy of unlocking its asset value by divesting assets outside of its core business while simultaneously providing additional liquidity, which it considers important in the current economic environment.
