Cautionary Statements and Supplemental Information

Forward-Looking Statements

Certain expectations and projections regarding our future performance referenced in this presentation, in other reports or statements we file with the SEC or otherwise release to the public, and
on our website, are forward-looking statements. Senior officers and other employees may also make verbal statements to analysts, investors, regulators, the media and others that are forward-
looking. Forward-looking statements involve matters that are not historical facts, such as statements regarding our future operations, prospects, strategies, financial condition, economic
performance (including growth and earnings), industry conditions and demand for our products and services. Because these statements involve anticipated events or conditions, 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," "seek," "should," "target," "would," or similar expressions. Forward-looking statements contained in this presentation include, without limitation, statements regarding future
earnings per share, capital expenditures, pension expenses, contracted capacity rates, costs related to our asset portfolio, dividend growth and EBIT contribution and our priorities for 2012. Our
expectations are not guarantees and are based on currently available competitive, financial and economic data along with our operating plans. While we believe our expectations are
reasonable in view of the currently available information, our expectations are subject to future events, risks and uncertainties, and there are several factors - many beyond our control - that
could cause results to differ significantly from our expectations.

Such events, risks and uncertainties include, but are not limited to, changes in price, supply and demand for natural gas and related products; the impact of changes in state and federal
legislation and regulation, including changes related to climate change; actions taken by government agencies on rates and other matters, including regulatory approval of new partnerships;
concentration of credit risk; utility and energy industry consolidation; the impact on cost and timeliness of construction projects by government and other approvals, development project delays,
adequacy of supply of diversified vendors, unexpected change in project costs, including the cost of funds to finance these projects; the impact of acquisitions and divestitures including the
Nicor merger; limits on natural gas pipeline capacity; direct or indirect effects on our business, financial condition or liquidity resulting from a change in our credit ratings or the credit ratings of
our counterparties or competitors; interest rate fluctuations; financial market conditions, including disruptions in the capital markets and lending environment and the current economic
uncertainty; general economic conditions; uncertainties about environmental issues and the related impact of such issues; the impact of changes in weather, including climate change, on the
temperature-sensitive portions of our business; the impact of natural disasters such as hurricanes on the supply and price of natural gas; the outcome of litigation; acts of war or terrorism; and
other factors which are provided in detail in our filings with the Securities and Exchange Commission. Forward-looking statements are only as of the date they are made, and we do not
undertake to update these statements to reflect subsequent changes.

Supplemental Information

Company management evaluates segment financial performance based on earnings before interest and taxes (EBIT), which includes the effects of corporate expense allocations and on
operating margin. EBIT is a non-GAAP (accounting principles generally accepted in the United States of America) financial measure that includes operating income, other income and
expenses. Items that are not included in EBIT are financing costs, including debt and interest expense and income taxes. The company evaluates each of these items on a consolidated level
and believes EBIT is a useful measurement of our performance because it provides information that can be used to evaluate the effectiveness of our 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. Operating margin is a non-
GAAP measure calculated as operating revenues minus cost of goods sold and revenue taxes, excluding operation and maintenance expense, depreciation and amortization, and taxes other
than income taxes. These items are included in the company's calculation of operating income. The company believes operating margin is a better indicator than operating revenues of the
contribution resulting from customer growth, since cost of goods sold and revenue taxes are generally passed directly through to customers. In addition, in this presentation, the company has
presented a non-GAAP measure of both its net income and its earnings per share each adjusted to exclude expenses incurred with respect to the Nicor merger. As the company does not
routinely engage in transactions of the magnitude of the Nicor merger, and consequently does not regularly incur transaction related expenses with correlative size, the company believes
presenting net income and EPS excluding Nicor merger expenses provides investors with an additional measure of the company’s core operating performance. EBIT, operating margin, net
income excluding merger expenses (also referred to as adjusted net income) and EPS excluding merger expenses (also referred to as adjusted EPS) should not be considered as alternatives
to, or more meaningful indicators of, the company's operating performance than operating income, net income attributable to AGL Resources Inc. or EPS as determined in accordance with
GAAP. In addition, the company's EBIT, operating margin, adjusted net income and adjusted EPS may not be comparable to similarly titled measures of another company. Reconciliations of
non-GAAP financial measures referenced in this presentation are available on the company’s Web site at www.aglresources.com

does not directly serve retail customers in
Georgia), so weather risk largely mitigated

• Received approval in 2011 to use $11.6
million of Universal Service Funds to aid in
the construction of CNG stations and
equipment to serve retail and commercial
fleet customers

Virginia Natural Gas

• Steps to Advance Virginia’s Energy (SAVE) Act

o Filed for an accelerated infrastructure replacement
program in January 2012

period

• Weather Risk

o Approved WNA program using 30 year normal
weather

o Coverage of commercial customers became
permanent as part of the 2011 rate case

• 2011 Rate Case Outcomes - Recovery
Mechanisms

o Gas portion of bad debts are now recovered through
the purchased gas adjustment

o $3.1 million of costs previously recovered through
base rates now recovered through the company’s
gas cost recovery rate

Elizabethtown Natural Gas

• Utility Infrastructure Enhancement (UIE)

o Accelerated enhanced infrastructure program
created in response to Governor’s request for
increasing infrastructure investments to spur
economic recovery

o First phase of the program completed in 2010

o Received approval in May 2011 to invest an
additional $40 million under the program through
2012

o Costs recovered through periodic adjustments to
base rates

o Expect to file for extension of the program in 2012

• Operating margin weather normalization
program in effect

o Required to return portion of WNA surcharge to
customers if return on equity exceeds authorized
return of 10.3%

• Focus on conversion opportunities from fuel
oil users

• Expect additional capital projects to augment
supply diversity and system reliability and
explore CNG fueling

Florida City Gas & Chattanooga Gas

• Florida City Gas

o Agreed to stay-out in 2007 when approval
received to include acquisition adjustment
amortization in operating income and acquisition
adjustment asset balance in rate base for
regulatory reporting

o Five-year stay-out provision ends in 2012; rate
case filing will be evaluated after full integration
of Nicor

o Minimal weather risk

o Energy conservation program in place and
funded by customers via a per therm surcharge

• Chattanooga Gas

o Gas portion of bad debts recovered through the
purchased gas adjustment

o Energy conservation program provides
programmable thermostats and customer
education; costs recovered through asset
management agreement proceeds

o Promote natural gas as the better alternative due to low natural gas commodity prices and
increased spreads between natural gas and oil/propane

o Prepare for housing markets stabilization and increasing industrial and commercial demand

o Foster natural gas for transportation (CNG behind the city gates)

• Remain a low-cost leader within the industry

o Continue to control costs by focusing on productivity improvements, leveraging common
systems, standardization and scale

o Complete Nicor integration and set the foundation to be the industry leader in natural gas
distribution

Commitment Summary as of Dec. 31, 2011

($ in Millions)

2012 Industry Outlook

• Extremely low price spreads for storage and transportation remain the key fundamental
challenge

o Seeing storage spreads improve and transportation spreads decrease

• Rapid shale gas growth to-date likely to slow due to low prices caused by mild winter

o Although challenging for Sequent in Q3 2011, portfolio is better positioned to take
advantage of new constraints if they occur

• Continued focus on growing pipeline transportation portfolio through existing and expected
constraints - likelihood of constraints is reduced with lower gas rig count

• Fixed costs of asset portfolio remains high in 2012 with significant 50% drop off of fixed
costs in 2013

o 2012 is likely a year requiring patience as legacy asset costs roll-off

o 2013 fixed asset cost is projected to be $76 million less than in 2012 - a portion of this
will roll into income

• Competitor earnings challenges should lead to more wholesale consolidation

2012 Priorities & Objectives

• Expect to deliver $15 million to $30 million of EBIT

• Significantly grow fuel supply to power generators and other fee-based services

• Strategically enhance Sequent’s position in Canada to complement lower 48
states’ asset position

• Capitalize on areas of volatility - West/Midwest transport, East constraints

• Renew material AMA’s & asset portfolio at lower fixed costs

• Integrate Nicor wholesale business and combine C&I business into one system

• Extend Compass and Enerchange C&I growth

Storage

Market Fundamentals

• Storage fundamentals are cyclical - currently in low point of the cycle

o Natural gas market is growing

o Significant barriers now exist to develop new storage

• Natural gas in favor

o Commodity price of natural gas remains low relative to oil

o Initial production from new basins showing promise

o Renewable energy sources are growing, but economics often require subsidies
