(NYSE: CNP) today reported net income of $81 million, or $0.25 per diluted share, for the fourth quarter of 2005 compared to $100 million, or $0.29 per diluted share for the same period of 2004.

"I am very pleased with our overall progress and accomplishments in 2005," said David M. McClanahan, president and chief executive officer of CenterPoint Energy. "2005 was a year of significant milestones for our company, marking the end to our transition. We completed the sale of our power generation business and began to recover our authorized true-up balance through the implementation of a competition transition charge and the issuance of $1.85 billion of transition bonds. We repaid our high-cost $1.31 billion term loan, reduced other debt and restructured our credit facilities to reduce interest costs, extend maturities and improve terms. Now that our transition is behind us, we look forward to further improving our operating performance while we explore opportunities to grow in a disciplined manner." -more-

Operating income for the fourth quarter of 2004 totaled $104 million, consisting of $95 million for the TDU and $9 million for the transition bond company. Revenues increased in the fourth quarter of 2005 primarily due to continued customer growth with the addition of over 60,000 metered customers since December 2004, increased customer usage and the implementation of a competition transition charge (CTC) in September 2005. Operating expenses increased primarily due to higher transmission costs, labor and benefit-related expenses, tree trimming expenses, and increased franchise fees paid to the City of Houston under a new 30-year franchise agreement. Operating income for the year 2005 was $487 million, consisting of $448 million for the TDU and $39 million for the transition bond companies. Operating income for 2004 totaled $494 million, consisting of $441 million for the TDU, $38 million for the transition bond company, and a $15 million reversal of a reserve related to the final fuel reconciliation of the former integrated utility recorded in the fourth quarter of 2004. For the year 2005, revenues increased primarily due to continued customer growth, increased customer usage driven by warmer weather, higher transmission cost recovery and implementation of the CTC. Operating expenses increased primarily due to higher transmission costs, labor and benefit-related expenses, tree trimming expenses, depreciation and amortization, and the increased franchise fees paid to the City of Houston. Operating expenses for 2004 reflected an $11 million credit from a land sale. NATURAL GAS DISTRIBUTION Beginning with the fourth quarter of 2005, the natural gas distribution segment excludes the company's non-rate regulated natural gas sales and services business, which is now reported as a separate segment, "competitive natural gas sales and services". All prior period segment information has been reclassified to conform to the 2005 presentation. -more-

Higher margins from the addition of nearly 44,000 customers since December 2004 were more than offset by increased litigation reserves and increased bad debt expense associated with higher natural gas prices. Operating income for the year 2005 was $175 million compared to $178 million for 2004. The benefits from rate increases and customer growth were more than offset by reduced customer usage, increased bad debt expense and litigation reserves, and higher depreciation. In 2004, operating expenses reflected severance and associated benefit-related expenses due to an organizational restructuring. COMPETITIVE NATURAL GAS SALES AND SERVICES The competitive natural gas sales and services business is engaged in the sale of natural gas and related services primarily to commercial and industrial customers and electric and gas utility companies. This segment reported operating income of $30 million for the fourth quarter of 2005, compared to $16 million for the same period of 2004. The increase was primarily attributable to higher sales to utilities and favorable basis differentials across the pipeline capacity that the company controls. Operating income for the year 2005 was $60 million compared to $44 million for 2004. The increase was primarily attributable to the same items noted above. Partially offsetting the margin increase were the effects of mark-to-market accounting related to non-trading financial derivatives used to lock in economic margins of certain forward gas sales, as well as increased employee-related and bad debt expenses. PIPELINES AND FIELD SERVICES The pipelines and field services segment reported operating income of $67 million for the fourth quarter of 2005 compared to $57 million for the same period of 2004. Within this segment, the pipeline business achieved higher operating income ($46 million vs. $42 million) driven by increased demand for transportation resulting from basis differentials across the system and higher demand for ancillary services. The field services business achieved higher operating income ($21 million vs. $15 million) driven by increased throughput and demand, increased gas gathering and ancillary services, and higher commodity prices. -more-

Operating income for the pipeline business for 2005 was $165 million compared to $129 million for 2004. The field services business recorded operating income of $70 million for 2005 compared to $51 million for 2004. The improvements in operating income for the year resulted primarily from the same items noted for the quarter. OTHER OPERATIONS The company's other operations reported an operating loss of $6 million for the fourth quarter of 2005 compared to a loss of $15 million for the same period of 2004. The operating loss for the year 2005 was $18 million compared to a loss of $32 million for 2004. OTHER 2005 EVENTS Additional significant events for CenterPoint Energy during 2005 included: o completion of the sale of the company's generation assets; proceeds of $2.231 billion and $700 million were received in 2004 and 2005, respectively; o issuance of over $1.85 billion in transition bonds to recover a portion of the company's authorized true-up balance; o implementation of a CTC to begin recovering the remaining authorized true-up balance of $596 million over 14 years, plus interest; o contribution of $75 million to the pension plan in 2005 following a $476 million pension plan contribution in 2004; and o completion of an exchange offer for $572 million of the company's 3.75 percent convertible senior notes. DIVIDEND DECLARATION On January 26, 2006, CenterPoint Energy's board of directors declared a regular quarterly cash dividend of $0.15 per share of common stock payable on March 10, 2006, to shareholders of record as of the close of business on February 16, 2006. In declaring this dividend, the board of directors indicated its intent to return to the company's traditional practice of paying consistent quarterly dividends. An annualized dividend based on a $0.15 per common share quarterly dividend represents a 50 percent increase over the $0.40 per common share in total dividends paid by the company in 2005. -more-

This guidance excludes any impacts related to the company's Zero-Premium Exchangeable Subordinated Notes (ZENS) and associated federal income tax consequences due to the uncertainties associated with the resolution of the ongoing dispute with the Internal Revenue Service.

In particular, the company has made certain assumptions regarding the impact to earnings of various regulatory proceedings but cannot predict the ultimate outcome of any of those proceedings. In providing this guidance, the company has not projected the impact of any potential changes in accounting standards, any impact from acquisitions or divestitures, or the outcome of pending legal proceedings related to the company's true up appeal.

In periods where only the term loan was assumed to be repaid, the actual interest paid was reclassified. In periods where a portion of the revolver was assumed to be repaid, the percentage of that portion of the revolver to the total outstanding balance was calculated, and that percentage was applied to the actual interest paid in those periods to compute the amount of interest reclassified. Total interest expense was $228 million and $162 million for the three months ended December 31, 2004 and 2005, respectively, and $849 million and $711 million for the year ended December 31, 2004 and 2005, respectively. Interest expense of $34 million for the three months ended December 31, 2004, and $72 million for the year ended December 31, 2004, was reclassified to discontinued operations of Texas Genco.
