We continue to work diligently on the merger between Superior and Complete Production Services, and we are getting closer to finalizing the deal, which will double the size of our company. Every day there are new developments and, as promised, I want to keep you informed of the latest news. On the regulatory front, here is an update of our progress.

In any corporate merger of this magnitude between two publicly traded companies, the details of the transaction must be reviewed and approved by two government entities, the Federal Trade Commission (FTC) and the Securities and Exchange Commission (SEC).

The FTC requires that before certain mergers can close, both companies must file a Notification and Report Form. This allows the FTC and the Department of Justice up to 30 days to request further information to ensure the transaction does not violate any antitrust laws. I am pleased to report we recently received notice from the FTC that we have been given early termination of the 30 day waiting period. This gives the merger some added momentum and will help keep us on track for our expected closing date which is projected to be as early as year-end.

In addition, on November 3 we filed with the SEC our joint proxy statement with Complete. A joint proxy statement contains information a company is required to provide to its shareholders so they can make informed decisions about matters that will be presented at each company’s respective special meeting of shareholders. We are currently waiting for a response from the SEC, and we will continue to keep you informed of the status.

I want to thank all of you for conducting business as usual during this time and for continuing to focus on service to our customers and workforce safety, both of which are critical. Again, if you would like to contact me directly with any questions or concerns, you can reach me at 281-999-0047 or dave.dunlap@superiorenergy.com.

FAQs

Will there be any layoffs?

 

A: This merger is about expansion not reduction of the work force, and there are no plans for layoffs. We are doing this to grow; not contract. Adding Complete’s approximately 7,500 employees to our current workforce of approximately 6,000 will only further improve our inventory of talented people.

What are the key terms of the deal?

 

A: Superior is acquiring Complete through a stock and cash consideration. Under the terms of the agreement, Complete stockholders will receive 0.945 common shares of Superior and cash of $7.00 in exchange for each share of Complete common stock held at closing. Upon closing, and reflecting the issuance of new Superior shares, Superior and Complete stockholders are expected to own approximately 52% and 48%, respectively, of Superior’s outstanding shares.
