Continental Resources Inc. founder Harold Hamm confirmed Thursday he and his second wife, Sue Ann, are getting a divorce.
Hamm, Continental's chairman and CEO, owns about 68 percent of the Oklahoma City oil company's outstanding shares. His stake is worth $10.88 billion, based on Thursday's closing price of $86.17 a share.
The confirmation came as wire service Reuters reported details of the divorce filing, which has been sealed by Oklahoma County Special District Judge Howard Haralson.
Hamm, 67, who chaired the energy advisory committee for Republican presidential candidate Mitt Romney, made the latest Forbes list of the world's richest people. The magazine put Hamm's estimated net worth at $11.3 billion, ranking him at No. 90.
The Hamms married in Las Vegas in 1988. In a short statement, Harold Hamm confirmed the divorce filing and said the matter was private.
“As they work through the process, Mr. Hamm is requesting privacy for the sake of his family and children,” the statement said. “The court has issued a confidentiality order and he wishes to honor that order.”
In a separate statement, Continental said the divorce proceeding “has not and is not anticipated to have any impact or effect on the company's business or operations.”
Oklahoma County court records show the divorce petition was filed under seal May 18 with “Jane Doe” as the plaintiff.
Records that have not been sealed in the case show Sue Ann Hamm's attorneys have asked Continental Resources to produce documents, along with documents from several private companies in which Hamm has an ownership stake.
Sue Ann Hamm is a former Continental employee but no longer works at the company. Her employment dates were not immediately available Thursday.
The court granted Sue Ann Hamm, 56, an interim distribution of $12 million in February, records show.
It's not the first time the Hamms have gone to divorce court. Harold Hamm filed for divorce in Garfield County in 1998, citing “irreconcilable incompatibility” and asked the court to grant him custody of the couple's daughters, Jane, now 22, and Hilary, now 19. That divorce petition was withdrawn about a month later.
Sue Ann Hamm filed for divorce in October 2005 in Oklahoma County. That case was withdrawn in December 2005.
Harold Hamm has three children from his first marriage, which ended in divorce in 1987.
