Deals move Oklahoma companies into and out of rankings

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.
