Constellation Energy Group Reports First Quarter 2003 Results

•Financial results consistent with Company forecasts

BALTIMORE, April 30, 2003 - Constellation Energy Group (NYSE: CEG) today reported earnings excluding special items of $59.1 million, equivalent to $0.36 per share, for the three months ending March 31, 2003.  Excluding the inter-quarter timing effect of a ($0.07) per share loss on hedges that were marked-to-market, first quarter earnings were $0.43 per share.  These results are consistent with the Company’s earnings guidance, provided in January 2003, of $0.33 to $0.43 per share.

As expected and previously disclosed, two new accounting standards affected the industry and resulted in a net charge to Constellation’s earnings of ($198.4) million, or ($1.20) per share.  In addition, the company recognized a net gain of $7.9 million after tax, or $0.04 per share, primarily associated with the sale of non-core assets.  Including both of these, the company reported a GAAP net loss of ($131.4) million, or ($0.80) per share, for the quarter.  An addendum detailing accounting changes and special items is attached.

The following table summarizes both earnings per share excluding special items and earnings per share reported in accordance with GAAP for the first three months of 2003 and 2002:

 “Our financial results this quarter mark the 6th consecutive quarter in which we have delivered on our earnings guidance,” said Mayo A. Shattuck III, Constellation Energy's Chairman, President and Chief Executive Officer. “We can attribute our strong performance to our continued focus on executing our business strategy while improving our competitive position.  As 2003 progresses, we continue to expand our competitive supply business in which we provide a comprehensive range of services to large energy consumers.  We have demonstrated superior management of plant construction and outages, completing two major projects in California and Maryland in April well ahead of schedule.  And, we delivered record earnings in the first quarter from our regulated utility.  Because of our diversification along the value chain and highly effective risk management structure, we were successful in navigating one of the most turbulent quarters in energy market history and are on track to meet our 2003 earnings forecast as presented in January.  This points to the underlying strength of our balanced business model, which we are confident will continue to perform well in 2003.”

Merchant Energy

The merchant energy business had a loss of ($0.13) in reported GAAP earnings per share for the first quarter of 2003.  Excluding special items, the merchant energy business reported a loss of ($0.12) per share in the first quarter of 2003, compared to earnings of $0.18 per share in the first quarter of 2002.  Earnings declined compared to the same quarter last year primarily due to:

•Lower mark-to-market earnings;

•The impact of volatile gas and power prices, cold northeastern weather, and outages at third party plants;

•The negative impact of three gas-fired plants brought on line after the first quarter of 2002; and

•The absence of 2002 first quarter income related to the reversal of a reserve for California utilities that began making payments.

These negatives were partially offset by the positive impact of:

•Wholesale accrual origination earnings;

•Earnings from our recent acquisitions — NewEnergy and Alliance — in the competitive supply business; and

•Favorable effects of our productivity initiatives.

These earnings also reflect the impact of a ($0.07) per share mark-to-market loss in this quarter on hedges in our competitive supply portfolio.  EITF 02-3 resulted in the conversion of many positions to accrual accounting effective January 1, 2003.  Several valid economic hedges did not qualify for accrual accounting hedge treatment and remained in the mark-to-market portfolio.  As a result, losses on these hedges were recognized in the first quarter, but we expect an approximately offsetting gain to be recognized in accrual earnings in the second through fourth quarters of this year.  This results in no net impact on our 2003 outlook.  Excluding the impact of these hedges, Merchant Energy would have recorded a loss excluding special items of ($0.05) per share for the quarter, in line with forecasts we provided in January and total company earnings excluding special items would have been $0.43 per share, at the top end of the guidance range provided in January.

Baltimore Gas and Electric

Baltimore Gas and Electric reported GAAP earnings and earnings excluding special items of $0.48 per share for the first quarter of 2003, compared to $0.35 per share excluding special items in the first quarter of 2002. The utility’s earnings benefited from higher electric volumes due to colder weather in its central Maryland service territory, lower interest expense, and favorable expense performance.

Other Nonregulated Businesses

Our other nonregulated businesses reported GAAP earnings of $0.05 per share for the first quarter of 2003.  Excluding special items, earnings from our other nonregulated businesses improved to $0.00 per share compared with a loss of ($0.04) per share in the first quarter of 2002.  The nonregulated businesses benefited from improved performance at BGE Home.

The March 2003 Financial Statements are attached.

Earnings Excluding Special Items

Constellation Energy presents earnings excluding special items in addition to its reported earnings per share in accordance with generally accepted accounting principles (Reported GAAP EPS).  Constellation Energy also provides its earnings guidance in terms of earnings excluding special items.  Earnings excluding special items is a non-GAAP financial measure that differs from Reported GAAP EPS because it excludes the cumulative effects of changes in accounting principles and other special items included in operations.  We exclude special items (which we define as items that are not related to our ongoing, underlying business or which distort comparability of results) because we believe that it is appropriate for investors to consider results excluding these items in addition to our results in accordance with GAAP.  We believe such a measure provides a picture of our results that is comparable among periods since it excludes the impact of items such as gains or losses on sales of non-core investments and workforce reduction costs, which may recur occasionally, but tend to be irregular as to timing, thereby distorting comparisons between periods.  Investors should note that this non-GAAP measure involves judgments by management (in particular, judgments as to what is or is not classified as a special item).  This non-GAAP measure is also used to evaluate performance and for compensation purposes.

Addendum — Accounting Changes and Special Items Recognized in First Quarter 2003

Cumulative Effects of Changes in Accounting Principles — net pre-tax charge of ($317.9) million, or ($1.20) per share

As previously expected and disclosed, in the first quarter of 2003 Constellation Energy recognized a net charge to earnings of ($1.20) per share from the cumulative effects of changes in accounting principles.  This consisted of a ($430.0) million pre-tax charge to earnings, or ($1.61) per share, relating to the January 1, 2003 implementation of Emerging Issues Task Force (EITF) consensus on Issue 02-3, Recognition and Reporting of Gains and Losses on Energy Trading Contracts Under EITF Issues No. 98-10 and No. 00-17, and a $112.1 million pre-tax gain, or $0.41 per share, relating to the January 1, 2003 implementation of Statement of Financial Accounting Standards No. 143, Accounting for Asset Retirement Obligations.

Special Items — $13.0 million net pre-tax gain, or $0.04 per share

Net Gains on Sales of Investments and Other Assets — $13.7 million pre-tax

In the fourth quarter of 2001, we announced our decision to focus efforts and capital on core domestic energy businesses and undertook a plan to sell a number of non-core businesses and investments. In the first quarter of 2003, we recognized approximately $13.7 million in pre-tax gains relating to the monetization of several non-core assets including:

•A $7.2 million pre-tax gain on the sale of an oil tanker to the U. S. Navy;

•A $5.3 million pre-tax gain on the favorable settlement of a contingent obligation we had previously reserved relating to the sale of our Guatemalan power plant operation in the fourth quarter of 2001; and

•A $1.2 million pre-tax installment sale gain on a parcel of real estate.

Workforce Reduction Costs — ($0.7) million pre-tax

We incurred ($0.7) million in expense associated with deferred payments to employees eligible for the 2001 Voluntary Special Early Retirement Programs.
