ATLANTA, April 30, 2013 - AGL Resources Inc. (NYSE: GAS) today reported first quarter 2013 net income of $154 million, or $1.31 per basic and diluted share. Earnings before interest and taxes (EBIT) were $304 million.

(1) A reconciliation of these non-GAAP measures to GAAP financial measures can be found at the end of this release.

"With weather that was 5% colder-than-normal in Illinois and slightly colder-than-normal in Georgia, our first quarter performance significantly improved year-over-year when compared to record warm weather in 2012. Beyond weather effects, our strategic approach of utilizing a shared services model continues to bring benefits to our customers and shareholders through the optimization of operations and maintenance expenses," said John W. Somerhalder II, chairman, president and chief executive officer of AGL Resources. "Our wholesale services and midstream operations remain challenged in an environment of low natural gas price volatility, but we have positioned them to operate more efficiently. With a strong first quarter complete, we reaffirm our 2013 earnings per share guidance of $2.50 to $2.70 per share."

FIRST QUARTER 2013 EBIT RESULTS BY SEGMENT
(in millions)

(1)     Before noncontrolling interest of $10 million for 1Q13 and $9 million for 1Q12.
(2)     Includes $10 million of Nicor merger-related expense in 1Q12.

Distribution Operations EBIT Variance Drivers

• Weather in Illinois was 34% colder than first quarter 2012, resulting in a $14 million EBIT improvement year-over-year at Nicor Gas.
  • 5% colder-than-normal weather in Illinois resulted in an EBIT benefit vs. normal weather of $2 million during the first quarter of 2013.
• EBIT improved $8 million as a result of increased revenues from regulatory infrastructure programs at Atlanta Gas Light.
• Operations and maintenance expense was essentially flat year-over-year, excluding pass through expenses and depreciation and amortization, as we achieved efficiencies that offset inflationary costs.
• Depreciation and amortization was higher by $2 million year-over-year as a result of infrastructure improvements.

Retail Operations EBIT Variance Drivers

• Weather in Georgia was 49% colder than first quarter 2012, resulting in a $10 million EBIT improvement year-over-year.
  • Weather was 1% colder-than-normal, resulting in an EBIT benefit vs. normal weather of $4 million during the first quarter of 2013.
• The January 31, 2013 acquisition of 500,000 retail warranty contracts contributed $1 million of EBIT.
• Operations and maintenance expense was in line with the prior year.

Wholesale Services EBIT Variance Drivers

• Commercial activity was higher by $26 million compared to the same period in the prior year, driven primarily by the recognition of operating margin resulting from the physical withdrawal of storage economically hedged at the end of 2012.
• Higher commercial activity was offset by:
  • Storage hedge losses of $17 million in first quarter 2013 compared to storage hedge gains of $19 million in first quarter 2012, and
  • Hedge losses of $4 million compared to hedge gains of $9 million in first quarter 2012 related to natural gas transportation positions.
• The storage rollout schedule is $34 million as of March 31, 2013 compared to $27 million at December 31, 2012 and $19 million at March 31, 2012.

Midstream Operations EBIT Variance Drivers

• First quarter 2013 EBIT decline was driven by higher operating expenses related to new facilities being placed into service in 2012, partially offset by slightly higher operating margin and other income from equity interest in Horizon pipeline.

Cargo Shipping EBIT Variance Drivers

• First quarter 2013 EBIT improvement was driven by a 10% increase in twenty-foot-equivalent units and lower depreciation and amortization expense.

INTEREST EXPENSE, INCOME TAXES AND MINORITY INTEREST

• Interest expense for the first quarter of 2013 was $46 million, a decline of $1 million compared to the first quarter of 2012.
• Income tax expense for the first quarter of 2013 was $94 million compared to $80 million first quarter of 2012 due to higher consolidated earnings for the quarter relative to the prior year.
• Net income attributable to noncontrolling interest for the first quarter of 2013 was $10 million compared to $9 million for the first quarter of 2012. This reflects the 15% ownership interest of our partner in SouthStar Energy Services.

Supplemental Information
Company management evaluates segment financial performance based on earnings before interest and taxes (EBIT), which include the effects of corporate expense allocations. EBIT is a non-GAAP (accounting principles generally accepted in the United States of America) financial measure that includes operating income and other income and expenses. Items that are not included in EBIT are income taxes and financing costs, including debt and interest expense, each of which the company evaluates on a consolidated basis.  The company believes EBIT is a useful measurement of its performance because it provides information that can be used to evaluate the effectiveness of its businesses from an operational perspective, exclusive of the costs to finance those activities and exclusive of income taxes, neither of which is directly relevant to the efficiency of those operations.

In addition, in this press release AGL Resources has presented a non-GAAP measure of adjusted earnings per share (EPS) that excludes expenses incurred with respect to the Nicor merger and a non-GAAP measure of adjusted EPS that excludes the wholesale services segment. As the company does not routinely engage in transactions of the magnitude of the Nicor merger, and consequently does not regularly incur transaction and integration-related expenses of correlative size, the company believes presenting EPS excluding Nicor merger-related expenses provides investors with an additional measure of AGL Resources' core operating performance. Examples of such expenses related to the merger and integration are: employee severance, relocation, consulting services, temporary labor and certain travel costs. In addition, the company believes that presenting EPS excluding wholesale services provides investors with additional measure of core operating performance excluding the volatility effects resulting from mark-to-market accounting in the wholesale services segment. Details related to these adjustments are included in the management discussion and analysis section of the Annual Report on Form 10-K. 

EBIT and adjusted EPS should not be considered as alternatives to, or more meaningful indicators of, the company's operating performance than net income attributable to AGL Resources Inc. or EPS as determined in accordance with GAAP. In addition, the company's EBIT and adjusted EPS may not be comparable to similarly titled measures of another company.

Reconciliation of non-GAAP financial measures referenced in this press release and otherwise in the earnings conference call and webcast is attached to this press release and is available on the company's Web site athttp://www.aglresources.com/ under the Investor Relations section.
