ITEM 8.01 Other Events

On September 24, 2007, Moody’s Investors Service: (1) downgraded the debt ratings of Energen Corporation (senior unsecured) to Baa3 from Baa2; and (2) confirmed the debt ratings of Alabama Gas Corporation (senior unsecured) at A1. Both companies’ ratings outlooks were changed to “Stable” from “Rating Under Review.” In a news release announcing its decisions, Moody’s said the downgrade of Energen’s debt ratings reflected the assignment of more weight to the parent company’s increased exposure to oil and gas exploration and production operations.

The information provided in this Form 8-K is furnished to, but not filed with, the Commission.
