Several companies have joined the Oklahoma Inc. pantheon, although they're not in this year's rankings because they didn't have a full year of results.
These newcomers, who should appear in next year's editions of Oklahoma Inc., should boost the rankings' energy-related bent.
Among the public offerings over the past year were two from SandRidge Energy Corp., which seemingly set the standard for such offerings this year in introducing investors to a pair of trusts.
The SandRidge Mississippian Trust, which trades as “SDT,” raised $340 million in April, followed by the SandRidge Permian Trust, “PER,” which at its initial offering grossed $621 million.
Other successful offerings from Oklahoma companies in 2011 included NGL Energy Partners in May and Compressco Partners in June.
Tulsa-based NGL netted $75.5 million from its initial public offering, while Compressco, which trades as “GSJK,” earned $54 million from becoming a public company.
Another planned IPO was canceled in October, robbing investors of a chance to buy into “JAWS.”
Oklahoma City-based Great White Energy Services withdrew its plans for an initial public offering after it was acquired by Bermuda-based Archer Limited.
Among the state-based offerings still being contemplated is an offering from Chesapeake Energy Corp. with a royalty trust that will hold a share of the proceeds from the company's Colony Granite Wash play in Washita County. That offering contemplates the sale of about 23 million common units, raising as much as $483 million.
Some Oklahoma Inc. firms made their final appearances in last year's rankings.
Pre-Paid Legal Services Inc. went private after the Ada company was acquired for $650 million by a New York-based private equity firm. The company, which sells a subscription to a package of limited legal services, has changed its name to LegalShield.
Broken Arrow-based XETA Technologies, a communications technology firm, was acquired by PAETEC Holdings Corp. in a $61 million deal.
And Bronco Drilling Co. was bought out by Chesapeake Energy Corp. in a $315 million transaction to merge into its current drilling company.
