NOVI, Mich., October 31 2013, ITC Holdings Corp. (NYSE: ITC) today announced its results for the third quarter and nine month period ended September 30, 2013.  Reported net income for the quarter, measured in accordance with Generally Accepted Accounting Principles (GAAP), was $59.0 million, or $1.12 per diluted common share, compared to $51.2 million or $0.98 per diluted common share for the third quarter of 2012.  For the nine months ended September 30, 2013, reported net income was $156.6 million, or $2.96 per diluted common share, compared to $139.6 million, or $2.68 per diluted common share for the same period last year.

Operating earnings for the third quarter of 2013 were $66.5 million, or $1.26 per diluted common share, compared to $56.1 million, or $1.07 per diluted common share for the third quarter of 2012. For the nine months ended September 30, 2013, operating earnings were $188.6 million, or $3.57 per diluted common share, compared to $159.5 million, or $3.05 per diluted common share for the same period last year.  Operating earnings are a non-GAAP measure that exclude the impact of the following after-tax expenses associated with:

·                  The Entergy Corporation (Entergy) transaction of approximately $7.5 million or $0.14 per diluted common share, and $5.0 million or $0.09 per diluted common share, for the third quarter 2013 and 2012, respectively. These expenses totaled approximately $31.9 million or $0.61 per diluted common share and $11.6 million, or $0.21 per diluted common share, for the nine months ended September 30, 2013 and 2012, respectively.

·                  An estimated refund liability of approximately $0.1 million for the third quarter 2013 recorded for certain acquisition accounting adjustments for ITC Midwest, ITCTransmission

and METC resulting from the FERC audit order on ITC Midwest issued in May 2012. For the nine months ended September 30, 2013 and 2012, amounts recorded associated with this matter totaled $0.2 million and $8.3 million or $0.16 per diluted common share respectively.

Operating earnings increased by $10.5 million, or $0.19 per diluted common share, for the third quarter compared to the same period in 2012. For the nine months ended September 30, 2013, operating earnings increased $29.1 million, or $0.52 per diluted common share, compared to the same period last year.  The increases in both periods were largely attributable to higher income associated with increased rate base and AFUDC at our operating companies, resulting from the continued execution of our capital investment plans.

ITC invested $648.9 million in capital projects at its operating companies during the first nine months of 2013, including $170.7 million at ITCTransmission, $127.8 million at METC, $245.8 million at ITC Midwest and $104.6 million at ITC Great Plains.

“Thus far, 2013 has proven to be a demanding year for us as we seek to continue to execute on our stand-alone initiatives while also advancing the Entergy transaction towards a successful close,” said Joseph L. Welch, chairman, president and CEO of ITC. “I am very pleased with how the organization has risen to meet this challenge and believe that we are well-positioned to meet our operational and financial objectives for the year.  We are also continuing to navigate the complex regulatory approval process for the Entergy transaction and hope to make meaningful progress with these efforts by year-end.”

EPS and Capital Expenditure Guidance

For 2013, ITC is updating its full year operating earnings per share guidance to a range of $4.84 to $4.92, from the previous range of $4.80 to $5.00.  Capital investment guidance for 2013 has also been updated to a range of $810 to $860 million, from the prior range of $760 to $860 million.  The updated guidance range includes capital forecasts at our regulated operating subsidiaries of $215 to $230 million for ITCTransmission, $170 to $180 million for METC, $285 to $300 million for ITC Midwest and $140 to $150 million for ITC Great Plains.

Third Quarter 2013 Operating Earnings Financial Results Detail

ITC’s operating revenues for the third quarter increased to $238.8 million compared to $214.8 million for the third quarter of 2012. This increase was primarily due to higher revenue requirements attributable to higher rate base at our regulated operating subsidiaries. In addition, regional cost sharing revenues increased due to additional capital projects being placed in-service that have been identified as eligible for regional cost sharing.

Operation and maintenance (O&M) expenses of $29.7 million decreased by $1.8 million compared to the same period in 2012. This decrease was primarily due to lower vegetation management requirements and lower NERC compliance activities associated with surveying overhead transmission lines.

General and administrative (G&A) expenses of $22.9 million were $2.4 million higher compared to the same period in 2012. The amounts for the third quarter 2013 and 2012 exclude approximately $9.0 million and $7.4 million, respectively, associated with adjustments to operating earnings relating to Entergy transaction costs noted previously.  This increase was primarily due to higher general business expenses, including an increase in information technology expenses and higher labor related expenses associated with personnel increases.  These increases were partially offset by lower outside legal fees.

Depreciation and amortization expenses of $29.8 million increased by $2.3 million compared to the same period in 2012 due to a higher depreciable base resulting from property, plant and equipment additions.

Taxes other than income taxes of $16.7 million were $2.0 million higher than the same period in 2012. This increase was due to 2012 capital additions at our regulated operating subsidiaries, which are included in the tax base for 2013 personal property taxes.

Interest expense of $43.0 million increased by $4.3 million compared to the same period in 2012. The amounts for the third quarter 2013 and 2012 exclude approximately $1.1 million and $0.2 million, respectively, associated with adjustments to operating earnings noted previously. This increase was due primarily to higher borrowing levels to finance capital investments.

The effective income tax rate for the third quarter of 2013 was 35.9 percent compared to 35.7 percent for the same period last year. The amounts for the third quarter 2013 and 2012 exclude approximately $2.6 million and $2.7 million, respectively, associated with adjustments to operating earnings noted previously.

Year-To-Date 2013 Financial Results Detail

ITC’s operating revenues for the nine months ended September 30, 2013 increased to $685.9 million compared to $619.9 million for the same period last year, which amount excludes an $11.0 million reduction in revenues associated with the ITC Midwest FERC audit-related refunds recorded for ITCTransmission, METC and ITC Midwest. This increase was primarily due to higher network revenues attributable to higher rate base at all of our regulated operating subsidiaries. In addition, the increase resulted from higher regional cost sharing revenues primarily due to additional capital projects being placed into service that have been identified as eligible for regional cost sharing.

O&M expenses of $83.9 million were $6.4 million lower for the nine months ended September 30, 2013 compared to the same period in 2012. This decrease was primarily due to lower vegetation management requirements and lower NERC compliance activities associated with surveying overhead transmission lines.

G&A expenses of $68.9 million were $7.5 million higher compared to the same period in 2012. The amounts for 2013 and 2012 exclude approximately $41.9 million and $17.4 million, respectively, associated with adjustments to operating earnings relating to Entergy transaction costs noted previously.  This increase was due to higher labor related expenses associated with personnel increases and higher professional services associated with legal, advisory and financial service fees.

Depreciation and amortization expenses of $87.6 million increased by $9.1 million for the nine months ended September 30, 2013 compared to the same period in 2012. This increase was primarily due to a higher depreciable base resulting from property, plant and equipment additions.

Taxes other than income taxes of $49.5 million were $5.3 million higher compared to the same period in 2012. This increase was due to 2012 capital additions at our regulated operating subsidiaries, which are included in the tax base for 2013 personal property taxes.

Interest expense of $121.8 million increased by $6.3 million compared to the same period in 2012. The amounts for year-to-date 2013 and 2012 exclude approximately $1.7 million and $1.4 million, respectively, associated with adjustments to operating earnings noted previously.
