Cautionary Statement Regarding Forward-Looking Statements

To the extent any statements made in this communication contain information that is not historical, these statements are forward-looking statements and are subject to uncertainties and risks. These forward-looking statements relate to, among other things, the expected benefits of the transaction such as efficiencies, cost savings, growth potential, and the expected timing of the completion of the transaction. Forward-looking statements often include words such as “anticipate,” “assume,” “believe,” “can,” “could,” “estimate,” “expect,” “forecast,” “future,” “goal,” “indicate,” “intend,” “may,” “outlook,” “plan,” “potential,” “predict,” “project,” “proposed,” “seek,” “should,” “target,” “would” or similar expressions. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements. Although certain of these statements set out herein are indicated above, all of the statements in this document that contain forward-looking statements are qualified by these cautionary statements. Although AGL Resources Inc. (the “Company”) believes that the expectations reflected in such forward-looking statements are reasonable, such statements involve risks and uncertainties, and undue reliance should not be placed on such statements. Certain material factors or assumptions are applied in making forward-looking statements, including, but not limited to, factors and assumptions regarding the items outlined above. Actual results may differ materially from those expressed or implied in such statements. Important factors that could cause actual results to differ materially from these expectations include, among other things, the following: the failure to receive, on a timely basis or otherwise, the required approvals in connection with the transaction with The Southern Company by the Company’s shareholders and government or regulatory agencies (including the terms of such approvals); the risk that another condition to closing of the merger may not be satisfied; and other risk factors relating to the energy industry, as detailed from time to time in the Company’s reports filed with the SEC. There can be no assurance that the transaction will in fact be consummated.

Additional information about these factors and about the material factors or assumptions underlying such forward-looking statements may be found in the body of this communication, as well as under Item 1.A in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2014, and Item 1.A in the Company’s most recent Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2015. The Company cautions that the foregoing list of important factors that may affect future results is not exhaustive. When relying on forward-looking statements to make decisions with respect to the Company, investors and security holders should carefully consider the foregoing factors and other uncertainties and potential events. All subsequent written and oral forward-looking statements concerning the transaction or other matters attributable to the Company or any other person acting on its behalf are expressly qualified in their entirety by the cautionary statements referenced above.

There also may be other factors that we do not anticipate or that we do not recognize are material that could cause results to differ materially from expectations. Forward-looking statements speak only as of the date they are made. The Company expressly disclaims any obligation to update or revise any forward-looking statement, whether as a result of future events, new information or otherwise, except as required by law.
