AMERICAN ELECTRIC POWER

Preliminary, unaudited results

COLUMBUS, Ohio, April 26, 2013 – American Electric Power (NYSE: AEP) today reported first-quarter 2013 earnings, prepared in accordance with Generally Accepted Accounting Principles (GAAP), of $363 million or $0.75 per share, compared with $389 million or $0.80 per share in first-quarter 2012. Operating earnings (excluding special items) for first-quarter 2013 were $387 million or $0.80 per share, compared with first-quarter 2012 operating earnings of $389 million or $0.80 per share.

For first-quarter 2013, operating earnings were $24 million, or $0.05 per share higher than GAAP earnings, due to a $30 million ($19 million, net of tax) reversal of a storm cost deferral due to a change in Virginia law and a $7 million restructuring charge ($5 million, net of tax) associated with additional sustainable cost-control efforts. A full reconciliation of 2013 GAAP earnings with operating earnings for the quarter is included in tables at the end of this news release.

“Our solid performance in the first quarter reflects our continued progress in advancing our earnings growth strategy,” said Nicholas K. Akins, AEP president and chief executive officer. “AEP’s Board increased our quarterly dividend April 23 by $0.02 to $0.49 per share based on its confidence in that strategy and in support of our goal to achieve a dividend payout ratio in the range of 60 to 70 percent of consolidated earnings.

“Strong residential and commercial sales combined with positive regulated rate recovery supported our first-quarter performance. Weather in the first quarter of 2013 was close to normal, but much better than last year’s very mild winter. The industrial segment of our business continues to struggle, and our projections point to continued overall flat demand. However, our employees are acutely focused on cost discipline and process improvements as we strive to continue delivering greater value to our customers and shareholders. The increase in Operations and Maintenance spending in the first quarter of 2013 is partially offset by rate trackers that provide dollar-for-dollar recovery in various jurisdictions,” Akins said.

“Our transmission business is delivering earnings improvement each quarter, and our performance to date this year has us on track to meet our 2013 transmission earnings goal of $0.14 per share. The positive decision last week from the Indiana Utility Regulatory Commission on the Pioneer project and the Transource Missouri settlement agreement filed earlier in April should allow us to make further progress this year on our longer-term transmission investment plan.

“We also continue to make progress on the transition to full competition in Ohio. The Public Utilities Commission of Ohio finalized approval of our corporate separation order, and we anticipate a decision soon from the Federal Energy Regulatory Commission on our plan to fully separate our Ohio generation from our Ohio utility operations. We remain on track to complete corporate separation of our Ohio assets at the end of 2013,” Akins said.

EARNINGS GUIDANCE

AEP reaffirmed its operating earnings guidance range for 2013 of $3.05 to $3.25 per share. In providing operating earnings guidance, there could be differences between operating earnings and GAAP earnings for matters such as, but not limited to, divestitures or changes in accounting principles. AEP management is not able to estimate the impact, if any, on GAAP earnings of these items. Therefore, AEP is not able to provide a corresponding GAAP equivalent for earnings guidance.

SUMMARY ONGOING RESULTS BY SEGMENT

$ in millions except EPS

Operating earnings from Utility Operations for first-quarter 2013 decreased $11 million compared with the same period in 2012. This reflects the negative impact of lower earnings due to customer switching in Ohio, partially offset by successful rate proceedings and the impact of colder weather in 2013 compared with mild temperatures in 2012. The difference between GAAP and operating earnings for first-quarter 2013 relates to the previously discussed reversal of a storm cost deferral due to a change in Virginia law and expenses related to cost-reduction initiatives.

Operating earnings from Transmission Operations for first-quarter 2013 increased $4 million compared with the same period last year due to increased transmission investment.

Operating earnings from AEP River Operations for first-quarter 2013 were $11 million lower than for the same period in 2012 primarily due to the 2012 drought, which continued to have negative impacts on river conditions and 2012 crop yields, resulting in reduced grain exports in 2013.

Operating earnings from Generation and Marketing for first-quarter 2013 increased $8 million compared with 2012 due to increased retail activity resulting from AEP’s 2012 acquisition of BlueStar Energy Solutions and higher trading and marketing margins, partially offset by lower wind production.

Operating earnings from All Other during first-quarter 2013 increased $8 million primarily due to a reduction in interest expense.

OPERATING MARGIN FROM UTILITY OPERATIONS

$ in millions

Retail Sales – Retail margins for first-quarter 2013 were $117 million higher than for the same period in 2012. In first-quarter 2013, AEP experienced colder weather throughout its service territories compared with the mild winter conditions last year. Retail margins also benefitted from the continuing favorable impact of rate decisions, partially offset by customer switching in Ohio. Retail Sales includes the East Regulated Integrated Utilities, Ohio Power Company, West Regulated Integrated Utilities and Texas Wires.

Off-System Sales – Margins from Off-System Sales were lower in first-quarter 2013 compared with the same period in 2012 primarily because of lower capacity revenues.

Transmission Revenue – 3rd Party – Transmission Revenue for first-quarter 2013 was $21 million higher than in the same period in 2012, primarily because of increased revenues in PJM, including revenues associated with customer switching.

Other Operating Revenue – Other Operating Revenue for first-quarter 2013 was $16 million higher than in first-quarter 2012, primarily due to an increase in revenues related to the securitization of stranded costs in Texas in March 2012.

SELECT OTHER OPERATING EXPENSES - UTILITY OPERATIONS

The following Utility Operations expense categories had significant fluctuations in first-quarter 2013 compared with first-quarter 2012 (dollars in millions):

Operations and Maintenance expense in first-quarter 2013 increased $85 million compared with the same period in 2012, of which approximately $44 million is the result of expenses associated with rate riders/trackers that provide dollar-for-dollar recovery. Higher costs from scheduled plant outages in 2013 and the February 2012 reversal of an obligation to make certain contributions resulting from the rejection of the Ohio modified stipulation also contributed to the increase. These increases were partially offset by continued discipline in controlling costs.

Depreciation and Amortization expense in first-quarter 2013 decreased $6 million compared with the same period in 2012 because of lower depreciation due to Ohio plant impairments in November 2012, partially offset by increases in depreciation rates in certain jurisdictions and higher depreciation related to the John W. Turk Jr. Power Plant, which was placed into service in December 2012.

Other Income & Deductions decreased in first-quarter 2013 by $27 million compared with the same period in 2012 due to lower AFUDC because of the Turk Plant going into service in December 2012 and carrying cost income associated with the Texas capacity auction true-up that was recognized in July 2011. The capacity auction true-up amount, including accrued interest, was securitized in March 2012.
