WASHINGTON – A Dickinson man, formerly the executive vice president of U.S. operations at a publicly traded Canadian oil-services company, pleaded guilty Wednesday to perpetrating a scheme to fraudulently inflate the company’s reported revenue, resulting in shareholder losses in excess of $886 million, according to the U.S. Department of Justice.

Court documents show Joseph Kostelecky, 60, admitted he engaged in a scheme to defraud while serving as the highest-ranking U.S. executive of Poseidon Concepts Corporation from about November 2011 to December 2012. Kostelecky admitted that, in his role, he caused Poseidon to falsely report about $100 million in revenue from purported long-term contracts with oil and natural-gas companies that were Poseidon’s customers.

Kostelecky’s misconduct included fraudulently directing Poseidon’s accounting staff at the U.S. corporate headquarters in Denver, Colorado, as well as its field office in Dickinson, to record revenue from such contracts and then assuring management that the associated revenue was collectable, when he knew that the contracts either did not exist or that the associated revenue was not collectable. After Poseidon reported a partial write-down of uncollectable accounts in its financial statements, resulting in a drop in the company’s stock price, Kostelecky fraudulently caused the issuance of a public filing falsely reporting that he had purchased a substantial number of shares of the company, when in fact he had made no such purchase.

Kostelecky admitted that when the inflated revenue came to light at the end of 2012, Poseidon’s stock price plunged and the company was forced into bankruptcy, causing over $886 million in shareholder losses. Kostelecky further admitted that he perpetrated the scheme to inflate the value of the company’s stock price and to enrich himself through the continued receipt of compensation and appreciation of his own stock and stock options.

Kostelecky pleaded guilty to one count of wire fraud and one count of securities fraud in the District of North Dakota. He is scheduled to be sentenced on Jan. 10 and faces a maximum penalty of 40 years in prison.

The U.S. Postal Inspection Service Criminal Investigation Group’s DOJ Mail Fraud Team is investigating the case.

Assistant Deputy Chief Anna G. Kaminska and Trial Attorney Jason M. Covert of the Criminal Division’s Fraud Section are prosecuting the case. The Securities and Exchange Commission and the U.S. Attorney’s Office for the District of North Dakota provided assistance.
