CENTERPOINT ENERGY REPORTS FOURTH QUARTER AND

FULL YEAR 2012 EARNINGS

Houston, TX – February 27, 2013 – CenterPoint Energy, Inc. (NYSE: CNP) today reported net income of $134 million, or $0.31 per diluted share, for the fourth quarter of 2012, compared to $117 million, or $0.27 per diluted share the previous year. Operating income for the fourth quarter of 2012 was $310 million dollars, compared to $274 million dollars for the same period last year.

For the year ended December 31, 2012, net income was $417 million, or $0.97 per diluted share. The results for the year include two unusual items recorded in the third quarter: (i) a $252 million non-cash goodwill impairment charge associated with the competitive energy services business, which has no tax effect, and (ii) a $136 million pre-tax ($88 million after-tax) gain associated with the acquisition of an additional 50 percent interest in a gathering and processing joint venture. Excluding the effects of these unusual items, net income would have been $581 million, or $1.35 per diluted share, for the year ended December 31, 2012.

For the year ended December 31, 2011, net income was $1.357 billion, or $3.17 per diluted share.

Net income for 2011 included $811 million, or $1.89 per diluted share, which reflects the final resolution of the appeals of the 2004 true-up order of the Texas Public Utility Commission issued in connection with the restructuring of the Texas electric industry. Excluding this amount, net income would have been $546 million, or $1.27 per diluted share, for the year ended December 31, 2011.

Operating income for the year ended December 31, 2012, was $1.038 billion, compared to $1.298 billion for the same period of 2011. Excluding the goodwill impairment charge, operating income for the year ended December 31, 2012, would have been $1.290 billion.

“CenterPoint Energy’s 2012 financial results highlight the strength of our balanced energy delivery business portfolio,” said David M. McClanahan, president and chief executive officer of CenterPoint Energy. “Our regulated electric and gas utilities continue to benefit from strong service territories, timely rate recovery mechanisms and effective expense management. Our midstream and energy services businesses performed well given the current market environment of low natural gas prices and minimal geographic price differentials. We continue to look for opportunities to invest in each of our businesses where we believe we can create value for our shareholders.”

Electric Transmission & Distribution

The electric transmission & distribution segment reported operating income of $99 million for the fourth quarter of 2012, consisting of $64 million from the regulated electric transmission & distribution utility operations (TDU) and $35 million related to securitization bonds. Operating income for the fourth quarter of 2011 was $93 million, consisting of $62 million from the TDU and $31 million related to securitization bonds.

Fourth quarter operating income for the TDU benefited from continued strong customer growth and the ongoing recognition of deferred equity returns associated primarily with the company’s true-up proceeds. These increases were partially offset by higher net transmission costs.

Operating income for the year ended December 31, 2012, was $639 million, consisting of $492 million from the TDU and $147 million related to securitization bonds. Operating income for the same period of 2011 was $623 million, consisting of $496 million from the TDU and $127 million related to securitization bonds.

Operating income from the TDU declined due to a return to more normal summer weather when compared to the previous year as well as impacts from new rates implemented in September 2011. These impacts were offset by the addition of more than 44,000 metered customers, ongoing equity returns associated with true-up proceeds, higher revenues associated with right-of-way easement grants, and decreased labor and benefits costs.

Natural Gas Distribution

The natural gas distribution segment reported operating income of $91 million for the fourth quarter of 2012, compared to $73 million for the same period of 2011. Operating income benefited from a return to more normal winter weather, rate changes, customer growth, and reduced operation and maintenance expenses, partially offset by an increase in depreciation.

Operating income for the year ended December 31, 2012, was $226 million, unchanged from the previous year, despite substantially reduced revenues from near record mild temperatures in the first quarter of 2012. Weather hedges and weather normalization rate structures, reduced operation and maintenance expenses, lower bad debt expense, the addition of more than 22,000 customers and the effect of rate changes offset these significant weather impacts.

Interstate Pipelines

The interstate pipelines segment reported operating income of $47 million for the fourth quarter of 2012, compared to $52 million for the same period of 2011. The decline was primarily due to contract expirations, reductions in ancillary services driven by lower commodity prices, and reduced off system transportation revenue due to a lack of geographic price differentials.

In addition to operating income, this segment recorded equity income of $6 million for the fourth quarter of both 2012 and 2011 from its 50 percent interest in the Southeast Supply Header (SESH).

Operating income for the year ended December 31, 2012, was $207 million, compared to $248 million for the same period of 2011. Operating income decreased due to a backhaul contract that expired in 2011, as well as reductions in compressor efficiency on the Carthage to Perryville pipeline. In addition, the full year was also impacted by reduced off-system transportation revenues, lower seasonal and market-sensitive transportation contracts and ancillary services.

This segment also recorded equity income of $26 million for the year ended December 31, 2012, from its 50 percent interest in SESH compared to $21 million for the same period of 2011. Higher earnings resulted primarily from restructuring and extending a long-term agreement with an anchor shipper at the end of 2011.

Field Services

The field services segment reported operating income of $61 million for the fourth quarter of 2012, compared to $53 million for the same period of 2011. Operating income for the fourth quarter of 2012 benefited from the timing of revenue recognition from contracts with throughput commitments, increased gathering services and retained gas volumes and additional income from acquisitions completed during the year. This was partially offset by lower commodity prices on the sales of retained natural gas and higher depreciation expense.

Operating income for the year ended December 31, 2012, was $214 million, compared to $189 million for the same period of 2011. Operating income improved primarily from increased margins from gathering projects in the Haynesville shale, growth in gathering services and retained gas volumes, and the acquisitions completed during the year. These were partially offset by lower commodity prices on sales of retained natural gas.

Equity income from Waskom was $5 million for the year ended December 31, 2012, compared to $9 million for the same period 2011 primarily due to the classification of earnings as operating income subsequent to the acquisition of the remaining 50 percent interest in Waskom in July 2012.

Competitive Natural Gas Sales and Services

The competitive natural gas sales and services segment reported operating income of $12 million for the fourth quarter of 2012, compared to $3 million for the same period of 2011. The improvement was driven primarily by the termination of uneconomic transportation contracts and an increase in retail sales customers and volumes. Fourth quarter operating income for 2012 included a loss of $1 million resulting from mark-to-market accounting for derivatives associated with forward natural gas transactions used to lock in economic margins, compared to gains of $1 million for the same period of 2011. The fourth quarter of 2011 included a $4 million write-down of natural gas inventory to the lower of average cost or market.

Operating income for the year ended December 31, 2012, was a loss of $250 million, compared to $6 million for the same period of 2011. Excluding a third quarter goodwill impairment charge, operating income for the year ended December 31, 2012, would have been $2 million. Operating income for the year ended December 31, 2012, included mark-to-market accounting charges of $16 million, compared to a gain of $8 million for the same period of 2011.
