Hartzog Conger Cason

A leading Oklahoma firm, Hartzog Conger Cason has more than 35 lawyers at its Oklahoma City office who represent a variety of clients, from individuals and families to not-for-profit organizations and commercial enterprises. The firm assists clients in a variety of sectors, with emphases on the energy, sports, food, aerospace, commercial lending and real estate sectors. Founded in 1979, the attorneys have developed a reputation in both the M&A and capital markets areas.  

Hartzog Conger & Cason’s M&A practice represents both buyers and sellers, including some of the biggest private equity firms.  

The firm grew over the research period with the additions of partners Mark McPhail and John Edwards, as well as with the additions of Scott Spradling, who is of counsel.

McAfee & Taft

Founded in 1952, McAfee & Taft is very strong in financial and corporate practice areas across a variety of sectors, including aerospace, agriculture, biotech, energy, oil and gas, food and health care. The state’s largest law firm, McAfee & Taft is based in Oklahoma City and it has offices in Tulsa and Springfield, Missouri.  

The corporate and financial team represents individuals, public and private corporations of all sizes, limited liability companies, partnerships and other forms of limited liability business organizations, private and public foundations, and other organizations involved in or contemplating any type of business or commercial transaction. The firm is also very active in merger and acquisition.  


Over the research period, the firm advised The Charles Machine Works on the sale of the company to The Toro for $700 million. The transaction is expected to close before August 2019. Another example can be seen in its representation of one of the nation’s top independent oil producers and Oklahoma’s largest state-chartered bank in their joint purchase of the Santa Fe Plaza Parking Garage. 

Porter Hedges

Beginning as a full-service Houston firm in 1981, the firm has cut out a unique niche dealing extensively with middle and lower market transactions, while still competing with the large coastal firms that have come to dominate Houston’s transactions.  

The firm is heavily involved with the oil and gas and healthcare industries, however they keep a diverse portfolio in dealing with business transactions of all sorts. 


Building on the firm’s Texas presence, Porter Hedges established their Oklahoma City office in 2014 in order to leverage mutual clients and further established relationships by putting a particular emphasis on advising corporate clients on upstream and midstream oil and gas transactions. 

The firm’s Oklahoma City team continues to be active in many local M&A transactions, including its representation of White Star Petroleum, a local Oklahoma City oil and gas company, in its sale of its interest in a midstream gathering system and associated assets  to 4 AM Midstream, a local midstream company. 


Porter Hedges’ capital markets group consists of six partners with expertise in representing issuers, underwriters, and trustees in public and private offerings and financings and financings of equity and debt securities across a broad array of industries, primarily focused in upstream, midstream alternative and oilfield services in the energy industry. The team’s experience can highlighted in serving as underwriter’s counsel for JP Morgan Securities in a public offering by Sanchez Energy Corporation of 10,500,000 shares of its common stock at a public offering price of $12.50. 

The firm’s powerhouse M&A practice represents public and private acquirers, targets, financial advisors, independent board committees, private equity funds, and other equity investors in domestic and international transactions. The team represented Five Point Capital Partners, a Houston based private equity firm, in the formation of San Mateo Midstream, along with Matador Resources Company. San Mateo Midstream will own, operate and expand natural gas, crude oil, and produced water midstream assets in the Delaware Basin, for a total value of $500 million at closing.  

The team’s restructuring practice represents debtors, creditors, trustees, creditors’ committees, institutional lenders and investors in connection with out of court debt restructurings, acquisitions and financings, in addition to Chapter 7, 9, and 11 bankruptcy cases throughout the US, with a particular focus on reorganisations. The firm’s restructuring practice can be seen in its representation of Business Property Lending, a wholly owned subsidiary of EverBank Financial Corporation, in prosecuting a creditor plan of liquidation and related disputes in the chapter 11 bankruptcy case of Cowboys Far West in the United States Bankruptcy Court for the Western District of Texas, San Antonio Division, with Everbank serving as the senior secured lender.
