WGL Holdings, Inc. Reports Increased Second Quarter Earnings and Raise

WASHINGTON, April 27 /PRNewswire-FirstCall/ -- WGL Holdings, Inc. (the Company), the parent company of Washington Gas Light Company (Washington Gas or the regulated utility) and other energy-related subsidiaries, today reported net income of $79.9 million, or $1.63 per share, for the three months ended March 31, 2005, the second quarter of its fiscal year 2005. This represents a $714,000, or $0.01 per share, increase over net income of $79.2 million, or $1.62 per share, for the three months ended March 31, 2004. For the first six months of fiscal year 2005, the Company reported net income of $123.1 million, or $2.51 per share, an increase of $4.3 million, or $0.08 per share, over the same period of the prior fiscal year. Unless otherwise noted, earnings per share amounts are presented in this news release on a diluted basis, and are based on weighted average common and common equivalent shares outstanding. The Company's operations are seasonal, and accordingly, the Company's operating results for the three and six months ended March 31, 2005 are not indicative of the results to be expected for the twelve months ended September 30, 2005.

Commenting on second quarter results and the outlook for the remainder of the year, WGL Holdings' Chairman and CEO James H. DeGraffenreidt, Jr. said, "Our strong second quarter results demonstrate our success in generating shareholder value from our non-utility businesses while continuing to grow our utility operations." DeGraffenreidt added, "Our energy-marketing and commercial HVAC businesses have improved sales and increased margins. We also profitably grew our utility customer base, adding nearly 27,500 active customer meters in the past year."

Net income presented for all periods ended March 31, 2004 has been restated to recognize the effect of a $1.2 million, or $0.02 per share, benefit associated with a Medicare prescription drug subsidy. This restatement was made in accordance with an accounting standard issued by the Financial Accounting Standards Board in 2004 and adopted by the Company during the third quarter of fiscal year 2004. This standard permitted recognition of this Medicare subsidy benefit on a retroactive basis effective January 1, 2004, the beginning of the Company's second quarter of fiscal year 2004. The effect of the restatement, which was reflected in the annual earnings reported for fiscal year 2004, is being presented for the first time in this earnings release as the Company presents detailed financial results for the quarter ended March 31, 2004. Accordingly, earnings for the second quarter of fiscal year 2004 were restated from $1.60 to $1.62 per share, and earnings for the six months ended March 31, 2004 were restated from $2.41 to $2.43 per share.

Results from Normal Operations

The Company reviews its financial results from normal operations (based on normal weather, and uninfluenced by unique transactions) to monitor its progress towards achieving its five-year financial objectives. Excluding the effects of colder-than-normal weather and unique transactions described below, the Company's consolidated earnings from normal operations for the second quarter of fiscal year 2005 were $1.53 per share, a $0.23 per share increase over earnings from normal operations of $1.30 per share for the same quarter of fiscal year 2004. For the first six months of fiscal year 2005, the Company's consolidated earnings from normal operations were $2.41 per share, a $0.26 per share increase over earnings from normal operations of $2.15 per share for the corresponding period of the prior fiscal year. The significant increase in earnings from normal operations for both the current quarter and year-to-date periods was due primarily to customer growth, reduced expenses including operation and maintenance, depreciation and amortization, and income taxes, as well as increased earnings from the Company's major non-utility operations.

As discussed above, earnings from normal operations exclude the impact of variations from normal weather and unique transactions. The Company's regulated utility operations are weather sensitive, with a significant portion of its revenue coming from deliveries of natural gas to residential and commercial heating customers. Weather, when measured by heating degree days, was seven percent colder and ten percent colder than normal for the three months ended March 31, 2005 and 2004, respectively, enhancing net income in relation to normal weather by an estimated $5 million, or $0.10 per share, for the current quarter, as compared to $10 million, or $0.20 per share, for the same quarter in fiscal year 2004. For the six months ended March 31, 2005 and 2004, weather was five percent colder and seven percent colder than normal, respectively, contributing an estimated $5 million to net income, or $0.10 per share, for the current six-month period, as compared to $10 million, or $0.20 per share, for the corresponding period of the prior fiscal year.

Earnings comparisons between the current and corresponding prior year periods presented also reflect unique transactions related to the Company's utility and non-utility segments. While there were no unique transactions in the current quarter and year-to-date periods, earnings from normal operations for the three and six months ended March 31, 2004 exclude the effect of an after-tax gain of $5.8 million, or $0.12 per share, realized in the second quarter of fiscal year 2004 from the sale of two buildings by a third party in a commercial development project in which the Company held a carried interest. Additionally, earnings from normal operations for the first six months of the prior fiscal year exclude the effect of additional depreciation expense unrelated to those periods of $3.5 million (pre-tax), or $0.04 per share, that was recorded in connection with a Virginia rate order.

Reconciliations of the Company's and regulated utility segment's earnings per share reported in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP) to earnings per share from normal operations are attached to this press release.

Three Months Ended March 31, 2005 Regulated Utility Operations

The operating results of the Company's regulated utility segment are the primary influence on consolidated operating results. For the three months ended March 31, 2005, the regulated utility segment reported net income of $74.6 million, or $1.52 per share, as compared to net income of $75.4 million, or $1.54 per share, for the same quarter of the prior fiscal year. This comparison reflects a decrease in total natural gas deliveries to firm customers of 22.6 million therms, or three percent, to 626.9 million therms delivered during the second quarter of fiscal year 2005. The decline in total natural gas deliveries reflects three percent warmer weather in the current quarter when compared to the same quarter in fiscal year 2004. Weather was seven percent colder than normal for the three months ended March 31, 2005, enhancing net income for the current quarter in relation to normal weather by an estimated $5 million, or $0.10 per share. Weather for the three months ended March 31, 2004 was ten percent colder than normal, contributing $10 million, or $0.20 per share, to earnings for that period.

Earnings for the regulated utility segment for the current quarter were favorably affected by the addition of nearly 27,500 active customer meters, an increase of 2.8 percent from the end of the same quarter of the prior fiscal year. The regulated utility segment also benefited during the current quarter from a $1.7 million (pre-tax), or three percent, decrease in operation and maintenance expenses, increasing net income by $0.02 per share when compared to the same quarter of fiscal year 2004. The lower expense primarily reflects fewer employees and lower employee severance costs, partially offset by higher labor rates and employee benefits expense.

Second quarter 2005 earnings for the regulated utility segment reflect a $1.5 million (pre-tax), or $0.02 per share, decrease in depreciation and amortization expense due primarily to a reversal in the current period of $1.0 million of depreciation expense that was previously recorded in fiscal year 2004 related to the performance of an earnings test required by a regulatory order in Virginia. Additionally, a $500,000 provision was recorded in the second quarter of fiscal year 2004 related to an earnings test that did not recur in the current quarter.

The regulated utility segment also benefited from reduced income taxes during the current three-month period due to a lower effective federal income tax rate (primarily attributable to a non-taxable benefit of a Medicare prescription drug subsidy) that contributed an additional $0.03 per share of increased earnings for this segment.

Non-Utility Operations

The Company's non-utility operations reported net income of $5.3 million, or $0.11 per share, for the three months ended March 31, 2005, as compared to net income of $3.9 million, or $0.08 per share, for the same three months of the prior fiscal year. The increased earnings from non-utility operations were attributable primarily to a $0.12 per share improvement in the operating results of the Company's retail energy-marketing segment. Results for the quarter ended March 31, 2004 included an after-tax gain of $5.8 million, or $0.12 per share, from the sale of a carried interest in real estate that did not recur in the current fiscal year.

The retail energy-marketing segment reported net income of $5.8 million, or $0.12 per share, for the current three-month period, compared to a net loss of $183,000 reported for the same three-month period of the prior fiscal year. The $6.0 million, or $0.12 per share, year-over-year improvement in earnings for this segment reflects higher gross margins from the sale of natural gas. Although natural gas sales volumes decreased slightly by one percent, gross margins per therm increased over three times. A significant portion of the higher gross margins from gas sales reflects the utilization of greater volumes of lower cost storage inventory, and the realization in the current quarter of market value gains associated with certain contracts used to hedge supply risks that occur due to the volatility in the price of natural gas. The retail energy-marketing segment also benefited during the current quarter from a relatively small improvement in gross margins from electric sales, reflecting a higher gross margin per kilowatt-hour sold that more than offset the affect of lower electric sales volumes caused by a reduced electric customer base.

The Company's commercial heating, ventilating and air conditioning (HVAC) segment reported a net loss of $256,000, or $0.01 per share, for the second quarter of fiscal year 2005, an improvement of $518,000, or $0.01 per share, over the net loss of $774,000, or $0.02 per share, reported for this segment for the same quarter of the prior fiscal year. This improvement primarily reflects increased sales and lower selling, general and administrative expenses during the period.

Six Months Ended March 31, 2005 Regulated Utility Operations

The regulated utility segment reported net income of $114.4 million, or $2.34 per share, for the first six months of fiscal year 2005, an increase of $4.4 million, or $0.09 per share, over net income of $110.0 million, or $2.25 per share, for the corresponding six-month period of the prior fiscal year.

Increased earnings for the regulated utility segment for the current six- month period reflect a 2.8 percent increase in active customer meters. The first six months of fiscal year 2005 also benefited $2.3 million, or $0.03 per share, from realizing the favorable effect of changes in rates charged to customers that were implemented in Maryland on November 6, 2003 and the District of Columbia on November 24, 2003. This benefit is net of the impact of a Virginia rate increase that went into effect on February 26, 2004, subject to refund, and included in this segment's operating results for the six months ended March 31, 2004, but that was not in effect during the six months ended March 31, 2005.

Total gas deliveries to firm customers fell 30.1 million therms, or three percent, to 1.021 billion therms delivered for the six months ended March 31, 2005, primarily due to warmer weather. Weather was two percent warmer in the current six-month period than in the comparable period of the prior fiscal year. Total gas deliveries to firm customers in the current six-month period also reflect declines experienced during the first three months of fiscal year 2005 that did not correlate with the change in heating degree days for that period. Weather was five percent colder than normal for the six months ended March 31, 2005, enhancing net income in relation to normal weather by an estimated $5 million, or $0.10 per share. Weather for the six-months ended March 31, 2004 was seven percent colder than normal, contributing $10 million, or $0.20 per share, to earnings for that period.

Current year-to-date earnings for the regulated utility segment benefited from a slight decline of $891,000 (pre-tax), or $0.01 per share, in operation and maintenance expense. The lower expense primarily reflects six percent fewer employees, and reduced employee severance costs, partially offset by the effect of higher labor rates and employee benefit costs.

Depreciation and amortization expense for the current six-month period declined by $4.6 million (pre-tax), or $0.06 per share. The current period reflects a reversal of $1.0 million (pre-tax), or $0.01 per share, of depreciation expense that was previously recorded in fiscal year 2004 related to the performance of an earnings test as required by a Virginia rate order. This reversal, combined with depreciation expense that was applicable to a prior period of $3.5 million, or $0.04 per share, recorded during the first six months of fiscal year 2004 in connection with a Virginia rate order, and depreciation expense of $500,000 recorded in connection with an earnings test in Virginia in the second quarter of fiscal year 2004, resulted in the favorable year-over-year expense comparison.

The regulated utility segment also benefited during the current year-to- date period from reduced income taxes due to a lower effective federal income tax rate (primarily attributable to a non-taxable benefit of a Medicare prescription drug subsidy) that contributed an additional $0.07 per share of increased earnings.

Non-Utility Operations

The Company's non-utility operations reported net income of $8.6 million, or $0.17 per share, for the six months ended March 31, 2005, relatively unchanged from the corresponding period of the prior fiscal year. The current six-month period reflects a $0.10 per share improvement in the earnings of the retail energy-marketing segment. The results for the same period of the prior fiscal year included a gain related to the sale of a carried interest in real estate that was almost equal to the earnings improvement of the retail energy- marketing segment for the current period.

The retail energy-marketing segment reported net income of $9.9 million, or $0.20 per share, for the six months ended March 31, 2005 as compared to net income of $4.6 million, or $0.10 per share, reported for the same period last fiscal year. The $5.3 million, or $0.10 per share, year-over-year improvement in earnings primarily reflects higher gross margins from the sale of natural gas, and a small increase in gross margins from electric sales despite significantly lower electric sales volumes.

The Company's commercial heating, ventilating and air conditioning (HVAC) segment reported a net loss of $688,000, or $0.02 per share, for the six months ended March 31, 2005, an improvement of $584,000, or $0.01 per share, over the same period last fiscal year. This improvement, driven primarily by this segment's operating results for the current second quarter, primarily reflects increased sales and lower selling, general and administrative expenses during the period.

Earnings Outlook

The earnings guidance shown below should be read in conjunction with a press release issued by WGL Holdings, Inc. on April 27, 2005 and entitled, "WGL Holdings, Inc. Subsidiary Updates Estimated Costs of System Rehabilitation Program in Prince George's County, Maryland."

The Company is raising its consolidated earnings estimate for the full fiscal year 2005 to a range of $1.94 to $2.04 per share from its previous guidance of $1.83 to $1.93 per share. This updated estimate includes an increase in projected full fiscal year 2005 earnings from its unregulated businesses to a range of $0.16 to $0.20 per share from the previous range of $0.09 to $0.13 per share. The annual guidance for the consolidated entity includes an estimate for the third quarter ending June 30, 2005 of a seasonal net loss in the range of $0.11 to $0.21 per share, which reflects projected earnings from the Company's unregulated businesses of $0.01 to $0.03 per share.

This guidance includes the estimated effect of actual weather through April 25, 2005, and assumes normal weather thereafter. These estimates also: (i) assume an anticipated level of costs and a rate of incurrence of such costs throughout the remainder of fiscal year 2005 in connection with a large project to be performed in Prince George's County, Maryland, and assume approval by the Public Service Commission of Maryland of Washington Gas' proposed accounting treatment for certain of these costs, (ii) assume no additional effect that may result from performing earnings tests pursuant to a December 18, 2003 rate order issued by the State Corporation Commission of Virginia, and (iii) exclude the effect of other unusual items that could arise in the future.

(CONSOLIDATED) RECONCILIATION OF REPORTED GAAP EARNINGS PER SHARE AND ADJUSTED EARNINGS PER SHARE (Unaudited)

The reconciliation below is provided to demonstrate management's utilization of historical earnings per share, as derived in accordance with Generally Accepted Accounting Principles in the United States of America (GAAP), and adjusted earnings per share from normal operations, a non-GAAP measure. This reconciliation is provided to more clearly identify the results from normal operations for WGL Holdings, Inc. and its consolidated subsidiaries (the Company), and identify certain unique transactions that are not expected to repeat. This information should assist investors and analysts to track progress towards achieving the Company's five-year objectives, which are based on normal weather and uninfluenced by single, one-time, non- repeating transactions.

Utilization of normal weather is an industry standard, and it is Company practice to provide estimates and guidance on the basis of normal weather. Actual performance and results may vary from normal weather projections, and the Company consistently identifies and explains this variation to assist users in the analysis of actual results versus the guidance. There may be other uses for the data, and the Company does not imply that this is the only use or the best use of this data for purposes of this analysis.
