AMERICAN ELECTRIC POWER

Preliminary, unaudited results

COLUMBUS, Ohio, Jan. 27, 2014 – American Electric Power (NYSE: AEP) today reported fourth-quarter 2013 earnings, prepared in accordance with Generally Accepted Accounting Principles (GAAP), of $346 million or $0.71 per share, compared with $21 million or $0.05 per share in 2012. Operating earnings (excluding special items) for fourth-quarter 2013 were $296 million or $0.60 per share, compared with fourth-quarter 2012 operating earnings of $242 million or $0.50 per share. The difference in fourth-quarter 2013 GAAP and operating earnings was primarily due to the reversal of a third-quarter Texas regulatory disallowance.

GAAP earnings for year-end 2013 were $1.480 billion or $3.04 per share, compared with $1.259 billion or $2.60 per share in 2012. Operating earnings for 2013 were $1.573 billion or $3.23 per share, compared with $1.497 billion or $3.09 per share in 2012.

For the year, operating earnings were $93 million, or $0.19 per share higher than GAAP earnings, due to the following items (net of tax): plant impairments of $124 million, or $0.25 per share; a $25 million, or $0.05 per share, regulatory disallowance resulting from a Virginia State Corporation Commission order related to the ownership transfer of Amos Plant Unit 3; a $19 million, or $0.04 per share, reversal of a storm cost deferral in Virginia; and a $5 million, or $0.01 per share, restructuring charge. These negative items were offset partially by the effects of a U.S. Supreme Court decision resulting in a favorable $80 million, or $0.16 per share, United Kingdom (U.K.) windfall profits tax credit.

A full reconciliation of 2013 and 2012 GAAP earnings with operating earnings for the quarter and year to date is included in tables at the end of this news release.

"Our solid financial performance in 2013, despite the loss of significant retail margins in Ohio, reflects our focus on our earnings growth strategy – investment in our core regulated operations, including our transmission business, and achieving cost savings through sustainable process improvements," said Nicholas K. Akins, AEP's chairman, president and chief executive officer. "We remain committed to growing earnings 4 to 6 percent off of our 2013 earnings guidance range of $3.05 to $3.25 per share.

"AEP shareholders received a 14.2 percent total return in 2013, including dividends, which exceeded the total shareholder return of 7.8 percent for the S&P 500 Electric Utilities Index. We increased our annual dividend by 6.4 percent, and our debt to total capitalization improved to 54.3 percent, the lowest ratio in 15 years. Additionally, our qualified pension plan funding reached 99 percent.

"We benefited from successful regulatory proceedings in several jurisdictions, and our transmission investments delivered earnings improvement in every quarter, with transmission nearly doubling its earnings contribution in 2013," Akins said.

"We completed corporate separation of our Ohio assets on schedule and received all necessary approvals to transfer our AEP Ohio generating assets Dec. 31, 2013, to regulated affiliates and our new competitive generation affiliate. We appreciate the constructive participation from the regulators and stakeholders who were engaged in this process.

"I'm most impressed with the diligence and performance of our employees over the last year. We completed a second consecutive year with no fatalities, and they demonstrated an incredible commitment to safety, environmental stewardship and process improvement. Their creativity and focus on doing things better have been amazing, and I'm confident that we'll identify additional sustainable savings as we expand our initiatives to more areas of the company," Akins said.

EARNINGS GUIDANCE

Management reaffirmed 2014 operating earnings guidance of $3.20 to $3.40 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, impairments 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 OF RESULTS BY SEGMENT

$ in millions

Operating earnings from Utility Operations for fourth-quarter 2013 and the year decreased compared with the same periods in 2012 by $39 million and $73 million, respectively. This reflects the negative impact of the transition to competition in Ohio, including reduced capacity payments in the PJM Interconnection (PJM), and a change in the effective tax rate, partially offset by successful rate proceedings and the impact of colder weather in the first and fourth quarters of 2013 compared with milder weather in 2012.

Operating earnings from Transmission Operations for fourth-quarter 2013 and the year increased compared with the same periods in 2012 by $14 million and $36 million, respectively, due to increased transmission investment.

Operating earnings from All Other for fourth-quarter 2013 and the year increased $61 million and $107 million, respectively, compared with the same periods in 2012, primarily as a result of increased interest income associated with a favorable court decision related to U.K. windfall profit taxes and costs associated with the early retirement of parent debt in fourth-quarter 2012.

OPERATING MARGIN FROM UTILITY OPERATIONS

$ in millions

Retail Sales – Retail margins for fourth-quarter 2013 and the year were $82 million and $230 million higher, respectively, than for the same periods in 2012. Retail margins benefited from the favorable impact of rate decisions, partially offset by customer switching in Ohio. Additionally, in the first and fourth quarters of 2013, AEP experienced colder weather throughout its service territories compared with milder winter conditions in 2012. Retail sales include the East Regulated Integrated Utilities, Ohio Power Company, West Regulated Integrated Utilities, and Texas Wires.

Off-System Sales – Margins from Off-System Sales were $5 million higher for fourth-quarter 2013 and $93 million lower for the year compared with the same periods in 2012. The decrease for the year is primarily due to reduced capacity payments in PJM, lower trading activity and true-ups related to prior-period PJM expenses.

Transmission Revenue – 3rd Party – Transmission Revenue for fourth-quarter 2013 and the year was $22 million and $85 million higher, respectively, than for the same periods in 2012, primarily because of increased revenues in PJM, including revenues associated with customer switching.

SELECT OTHER OPERATING EXPENSES - UTILITY OPERATIONS

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

Operations and Maintenance expenses in fourth-quarter 2013 and the year were $68 million and $153 million higher, respectively, when compared with the same periods in 2012. Approximately three-fourths of the yearly difference is the result of expenses associated with rate riders/trackers that provide dollar-for-dollar recovery. The remaining difference is primarily attributable to incremental plant outage work.

Depreciation and Amortization expense for the year decreased by $48 million when compared with the same period in 2012, primarily because of lower depreciation from Ohio plant impairments recorded in November 2012, partially offset by higher depreciation expense related to the Turk Plant entering service in December 2012.

Other Income & Deductions decreased in fourth-quarter 2013 and the year by $5 million and $45 million, respectively, when compared with the same periods in 2012, primarily due to lower Allowance for Funds Used During Construction related to the Turk Plant.

Taxes Other Than Income Taxes increased in fourth-quarter 2013 and the year by $16 million and $28 million, respectively, when compared with the same periods in 2012, primarily due to increased property taxes.
