BLACK HILLS CORPORATION Notes to Consolidated Financial Statements (unaudited) (Reference is made to Notes to Consolidated Financial Statements included in the Company's Annual Report and Form 10-K) (1) MANAGEMENT'S STATEMENT The financial statements included herein have been prepared by Black Hills Corporation (the Company) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations; however, the Company believes that the footnotes adequately disclose the information presented. These financial statements should be read in conjunction with the financial statements and the notes thereto, included in the Company's 2000 Annual Report on Form 10-K filed with the Securities and Exchange Commission. Accounting methods historically employed require certain estimates as of interim dates. The information furnished in the accompanying financial statements reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the March 31, 2001, December 31, 2000 and March 31, 2000, financial information and are of a normal recurring nature. The results of operations for the three and twelve months ended March 31, 2001, are not necessarily indicative of the results to be expected for the full year. (2) RECLASSIFICATIONS Certain 2000 amounts in the financial statements have been reclassified to conform to the 2001 presentation. These reclassifications did not have an effect on the Company's stockholders' investment or results of operations as previously reported. (3) CHANGE IN ACCOUNTING PRINCIPLE In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No. 133 (SFAS 133), "Accounting for Derivative Instruments and Hedging Activities." SFAS 133, as amended, establishes accounting and reporting standards requiring that every derivative instrument be recorded in the balance sheet as either an asset or liability measured at its fair value. The Statement requires that changes in the derivative instrument's fair value be recognized currently in earnings unless specific hedge accounting criteria are met. SFAS 133 allows special hedge accounting for fair value and cash flow hedges. The Statement provides that the gain or loss on a derivative instrument designated and qualifying as a fair value hedging instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk be recognized currently in earnings in the same accounting period. SFAS 133 provides that the effective portion of the gain or loss on a derivative instrument designated and qualifying as a cash flow hedging instrument be reported as a component of other comprehensive income and be reclassified into earnings in the same period or periods during which the hedged forecasted transaction affects earnings. The remaining gain or loss on the derivative instrument, if any, must be recognized currently in earnings. 6

SFAS 133 requires that on date of initial adoption, an entity shall recognize all freestanding derivative instruments in the balance sheet as either assets or liabilities and measure them at fair value. The difference between a derivative's previous carrying amount and its fair value shall be reported as a transition adjustment. The transition adjustment resulting from adopting this Statement shall be reported in net income or other comprehensive income, as appropriate, as the effect of a change in accounting principle in accordance with paragraph 20 of Accounting Principles Board Opinion No. 20 (APB 20), "Accounting Changes." On January 1, 2001, the Company adopted SFAS 133. The Company had certain non-trading energy contracts and interest rate swaps documented as cash flow hedges, which upon adoption resulted in a cumulative decrease to accumulated other comprehensive income of $10.1 million. Upon adoption of SFAS 133, most of the Company's energy trading activities previously accounted for under Emerging Issues Task Force Issue No. 98-10, "Accounting for Energy Trading and Risk Management Activities" (EITF 98-10) fell under the purview of SFAS 133. The effect from this adoption on the energy trading companies and energy trading activities was not material because, unless otherwise noted, the trading companies do not designate their energy trading activities as hedge instruments. This "no hedge" designation results in these derivatives being measured at fair value and gains and losses recognized currently in earnings. This treatment under SFAS 133 is comparable to the accounting under EITF 98-10. (4) COMPREHENSIVE INCOME The following table presents the components of the Company's comprehensive income: Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Net income available for common stock $32,050 $9,061 $75,623 $37,097 Other comprehensive income: Unrealized gain on available-for-sale securities 1,023 - 210 - Fair value adjustment on derivatives designated as cash flow hedges (9,953) - (9,953) - -------- ------ ------- ------- Comprehensive income $23,120 $9,061 $65,880 $37,097 ======= ====== ======= ======= (5) SUMMARY OF INFORMATION RELATING TO SEGMENTS OF THE COMPANY'S BUSINESS The Company's reportable segments are those that are based on the Company's method of internal reporting, which generally segregates the strategic business groups due to differences in products, services and regulation. As of March 31, 2001, substantially all of the Company's operations and assets are located within the United States. The 7

Company's operations are conducted through six business segments that include: Electric group and segment, which supplies electric utility service to western South Dakota, northeastern Wyoming and southeastern Montana; Independent Energy group consisting of the following segments: Mining, which engages in the mining and sale of coal from its mine near Gillette, Wyoming; Oil and Gas, which produces, explores and operates oil and gas interests located in the Rocky Mountain region, Texas, California and other states; Fuel Marketing, which markets natural gas, oil, coal and related services to customers in the East Coast, Midwest, Southwest, Rocky Mountain, West Coast and Northwest regions markets; Independent Power, which produces and sells power to wholesale customers; and Communications group and Others, which primarily markets communications and software development services. Segment information follows the same accounting policies as described in Note 1 of the Company's 2000 Annual Report on Form 10-K. Segment information included in the accompanying Consolidated Balance Sheets and Consolidated Statements of Income is as follows (in thousands): External Inter-segment Operating Revenues Operating Revenues Net Income (loss) (In thousands) Quarter to Date March 31, 2001 Electric $ 70,580 $ -- $ 17,337 Mining 5,407 2,856 2,066 Oil and gas 8,581 -- 2,956 Fuel marketing 452,299 3,592 15,559 Independent power 18,045 -- (1,106) Communications and others 3,925 1,101 (4,720) Intersegment eliminations -- (4,693) -- -------- -------- -------- Total $558,837 $ 2,856* $ 32,092 ======== ======== ======== *In accordance with the provisions of SFAS No. 71, intercompany coal sales are not eliminated.

During the quarter ended March 31, 2001, as part of the Company's restructuring plan associated with the new "holding company" structure effected in the fourth quarter 2000, the Company transferred ownership interest in Wyodak Development Corporation between its wholly-owned subsidiaries Black Hills Power and Black Hills Energy Ventures. This transaction had the effect of reducing the "Electric" reporting segment's total assets by approximately $89.6 million. Black Hills Energy Ventures is an "intermediate level" holding company and is not included in a reporting segment. The Company had no other material changes in total assets of its reporting segments beyond changes resulting from normal operating activities. 9

(6) LEGAL PROCEEDINGS On April 3rd, 2001, we reached a settlement of ongoing litigation with PacifiCorp filed in the United States District Court, District of Wyoming, (File No. 0cv-155B). The litigation concerned the parties' rights and obligations under the Further Restated and Amended Coal Supply Agreement dated May 5, 1987, by which PacifiCorp purchased coal from our coal mine to meet the coal requirements of the Wyodak Power Plant. The Settlement Agreement provided for the dismissal of the litigation, with prejudice, coupled with the execution of several new coal-related agreements between the parties discussed below. We believe the value of the Settlement Agreements is equal to the net present value of the litigated Further Restated and Amended Coal Supply Agreement. New Restated and Amended Coal Supply Agreement: Effective January 1, 2001, the parties agreed to terminate the Further Restated and Amended Coal Supply Agreement, and replace it with the New Restated and Amended Coal Supply Agreement (New Agreement). The New Agreement begins on January 1, 2001, and extends to December 31, 2022. Under the New Agreement, we received an extension of sales beyond the June 8, 2013 term of the former Coal Supply Agreement. PacifiCorp will receive a price reduction for each ton of coal purchased. The minimum purchase obligation under the New Agreement increased to 1,500,000 tons of coal for each calendar year of the contract term, subject to adjustment for planned outages. The New Agreement further provides for a special one-time payment by PacifiCorp in the amount of $7,374,000, to be paid on or before September 1, 2001. This payment will be recognized as revenue over the life of the New Agreement. Coal Option Agreement: The term of this agreement begins no later than October 1, 2001, and extends until December 31, 2010. The agreement provides that PacifiCorp shall purchase 1,400,000 tons of coal during the period of October 1, 2001 through December 31, 2002, and 1,000,000 tons of coal in 2003 at a fixed price. The agreement further provides us with a "put" option for 2002 and 2003 under which we may put to PacifiCorp up to 500,000 tons of coal from the Wyodak Mine at a market based price. For each calendar year from January 1, 2004 through 2010, the put option is increased to a maximum of 1,000,000 tons at a market based price. The "put" tonnages will be reduced or offset for quantities of K-Fuel purchased by PacifiCorp under the KFx Facility Output Agreement. Additionally, for each calendar year during which we are selling to PacifiCorp K-Fuel under the KFx Facility Output Agreement described below, and in which we have not exercised our "put" option, PacifiCorp may elect to purchase an equal amount of tonnage from our coal reserves to use in a 50/50 blend with the K-Fuel, up to 500,000 tons per year in 2002 through 2007 at a market based price with a fixed floor. Asset Option Agreement: This agreement provides PacifiCorp an option to purchase a 10% interest in the KFx facility or the legal entity that owns the KFx facility at a market based price. Additionally, the agreement provides to PacifiCorp an option to sell us PacifiCorp's interest in the "In Pit" conveyor system currently owned by PacifiCorp and utilized at the Wyodak Mine at a fixed price. If PacifiCorp exercises its option to sell us the In Pit system, we have a corresponding right to put to PacifiCorp the "North Conveyor System," which serves as the backup coal delivery system for the Wyodak Power Plant at a fixed price. KFx Facility Output Agreement: The KFx plant is a coal enhancement facility we own located near our Wyodak Coal Mine. The KFx plant was built to produce an enhanced coal known as "K-Fuel." Assuming the plant becomes operational, PacifiCorp agrees to purchase K-Fuel for a term beginning January 1, 2002, and extending to December 31, 2007. If the plant is not operational on or before December 31, 2003, the agreement will 10

become void. Under this agreement, PacifiCorp agrees to purchase the output of K-Fuel from the KFx plant, up to a maximum of 500,000 tons for each calendar year from 2002 through 2007 at fixed price with market based escalation. WRDC reserves the right to sell up to a total of 100,000 tons from the output of the KFx plant to other customers during the same time period. (7) PRICE RISK MANAGEMENT The Company is exposed to market risk stemming from changes in commodity prices. These changes could cause fluctuations in the Company's earnings and cash flows. In the normal course of business, the Company actively manages its exposure to these market risks by entering into various hedging transactions, which are authorized under its Risk Management Policies and Procedures that place clear controls on these activities. Hedging transactions involve the use of a variety of derivative financial instruments. The Company accounts for all energy trading activities at fair value as of the balance sheet date and recognizes currently the net gains or losses resulting from the revaluation of these contracts to fair value in its results of operations. As a result, substantially all of the energy trading activities of the Company's gas marketing, crude oil marketing, and coal marketing operations are accounted for under fair value accounting methodology as prescribed in SFAS 133 or EITF 98-10. The Company, through its independent energy business group, utilizes financial instruments for its fuel marketing services. These financial instruments include fixed-for-float swap financial instruments, basis swap financial instruments and costless collars traded in the over-the-counter financial markets. These derivatives are not held for speculative purposes but rather serve to hedge the Company's exposure related to commodity purchases or sales commitments. Under SFAS 133 and EITF 98-10, these transactions qualify as derivatives or energy trading activities that must be accounted for at fair value. As such, realized and unrealized gains and losses are recorded as a component of income. Because the Company does not as a policy permit speculation with "open" positions, substantially all of its trading activities are back-to-back positions where a commitment to buy/(sell) a commodity is matched with a committed sale/(buy) or financial instrument. The quantities and maximum terms of derivative financial instruments held for trading purposes at March 31, 2001 and 2000 are as follows: Max.

Non-trading Energy Activities ----------------------------- To reduce risk from fluctuations in the price of oil and natural gas, the Company enters into swaps and costless collar transactions. The transactions are used to hedge price risk from sales of the Company's forecasted crude oil and natural gas production. For such transactions, the Company utilizes hedge accounting as allowed under SFAS 133. At March 31, 2001, the Company had fixed-for-float swaps and costless collars to hedge portions of its crude oil and natural gas production. These transactions were identified as cash flow hedges, properly documented, and effectiveness testing established. At quarter-end, the hedges met the effectiveness testing criteria and retained their cash flow hedge status. The crude oil hedges recorded ineffectiveness due to basis risk and time value. The effective portion of the gain or loss on these derivatives is reported in other comprehensive income and the ineffective portion is reported in earnings. At March 31, 2001, the Company had fixed-for-float swaps for 17,000 barrels of crude oil per month through December of 2001 with a net fair value of $(0.2) million and 12

10,000 barrels of crude oil per month for January through September of 2002 with a net fair value of $0.2 million. The Company had costless collars (purchased put - sold call)for 10,000 barrels of crude oil per month for 2001 with a net fair value of $0.2 million. In addition, the Company hedged its forecasted 2001 natural gas production with fixed-for-float swaps. At March 31, 2001 these natural gas swaps were for 1,131,000 MMBtus with a net fair value of $(2.2) million. The effective portion of the gains and losses on these derivatives was recorded in other comprehensive income. At March 31, 2001, other comprehensive income for all non-trading energy swaps and options was $1.6 million. Derivative fair value gains and losses are recorded in other comprehensive income for the effective portion of the hedge and in earnings for the ineffective portion. The ineffective portion includes both time value and basis risk. The net gain recognized in earnings prior to actual cash settlement is $0.4 million. Financing Activities -------------------- To reduce risk from fluctuations in interest rates, the Company enters into interest rate swap transactions. These transactions are used to hedge interest rate risk for variable rate debt financing. For such transactions, the Company utilizes hedge accounting per the requirements of SFAS 133. These transactions were identified as cash flow hedges, properly documented, and effectiveness testing established. At quarter-end, these hedges met effectiveness testing criteria and retained their cash flow hedge status. At March 31, 2001, the Company had interest rate swaps with a average balance notional amount of $163.3 million, having a maximum term of six years and a fair value of $(12.4) million. Because these hedges are fully effective (no time value or basis risk), the entire derivative fair value is recorded in other comprehensive income. At March 31, 2001, the Company had $390.6 million of outstanding, floating-rate debt of which $214.5 million was not offset with interest rate swap transactions that effectively convert the debt to a fixed rate. Credit Risk ----------- In addition to the risk associated with price movements, credit risk is also inherent in the Company's risk management activities. Credit risk relates to the risk of loss resulting from non-performance of contractual obligations by a counterparty. While the Company has not experienced significant losses due to the credit risk associated with these arrangements, the Company has off-balance sheet risk to the extent that the counterparties to these transactions may fail to perform as required by the terms of each such contract. (8) SUBSEQUENT EVENTS Common Stock Offering --------------------- During the first quarter of 2001, the Company announced the public offering of 3 million shares of common stock with an option for the underwriters to purchase 450,000 additional shares. Credit Suisse First Boston, Lehman Brothers, CIBC World Markets and UBS Warburg acted as the managers of the underwriting syndicate. 13

Early in the second quarter of 2001 the Company announced the offering price was set at $52 per share and all 3 million shares were sold with the underwriters exercising their over-allotment option to purchase an additional 383,000 shares. Net proceeds were approximately $165 million after commissions and expenses. The proceeds will be used to fund a portion of the expansion and construction costs related to certain power plant assets of the Company's independent energy group, to repay a portion of current indebtedness under revolving credit facilities, and for general corporate purposes. Acquisitions ------------ Early in the second quarter of 2001, the Company's independent power subsidiary, Black Hills Energy Capital, closed on the purchase of the Fountain Valley facility, a 240 megawatt generation facility located near Colorado Springs, Colorado, featuring six LM-6000 simple-cycle, gas-fired turbines. The facility is currently under construction and is expected to come on-line early in the third quarter of 2001. The facility was purchased from Enron Corporation for approximately $175 million and was financed primarily with non-recourse financing from Union Bank of California. In addition, the Company has obtained an 11-year contract with Public Service of Colorado to utilize the facility for peaking purposes. The contract is a tolling arrangement in which the Company assumes no fuel risk. 14

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS We are a growth oriented, diversified energy holding company operating principally in the United States. Our regulated and unregulated businesses have expanded significantly in recent years. Our independent energy group produces and markets power and fuel. We produce and sell electricity in a number of markets, with a strong emphasis in the western United States. We also produce coal, natural gas and crude oil primarily in the Rocky Mountain region and market fuel products nationwide. We also own Black Hills Power, Inc., an electric utility serving approximately 58,600 customers in South Dakota, Wyoming and Montana. Our communications group offers state-of-the-art broadband communications services to residential and business customers in Rapid City and the northern Black Hills region of South Dakota. The following discussion should be read in conjunction with Item 7. - Management's Discussion and Analysis of Financial Condition and Results of Operations - included in our 2000 Annual Report on Form 10-K filed with the Securities and Exchange Commission. Our business and industry outlooks, capital requirements and market risks as disclosed in that filing continue to be consistent with management's current expectations and assessments. Results of Operations Consolidated Results Consolidated earnings for the three month period ended March 31, 2001 were $32.1 million or $1.37 per share compared to $9.1 million or $0.42 per share in the same period of the prior year. Consolidated earnings for the twelve month period ended March 31, 2001 were $75.6 million or $3.32 per share compared to $37.1 or $1.72 per share for the same period of the prior year. Increases in earnings for the three and twelve month periods ended March 31, 2001 were primarily driven by strong natural gas marketing activity, increased fuel production, expanded power generation and increased wholesale off-system utility sales. Strong results in our independent energy business group and electric utility business group were partially offset by losses in our communications group and increased reserves for exposure to the unstable markets in the western United States. Unusual energy market conditions in the western United States continue to contribute to our strong financial performance. We estimate approximately half of the current three month period's and one-third of the current twelve month period's earnings per share could be attributable to high prices of natural gas and electricity related to the volatile western markets. Consolidated revenues for the three and twelve month periods ended March 31, 2001 were $561.7 million and $1.9 billion, respectively. Revenues for the same periods ended March 31, 2000 were $248.0 million and $871.6 million, respectively. The growth in revenues was a result of high energy commodity prices and increased volumes of fuel marketed, primarily as a result of extreme price volatility in the western markets, acquisitions and growth in the independent energy business group and increases in off-system sales by our electric utility. 15

Revenue and net income (loss) provided by each business group as a percentage of our total revenue and net income were as follows: Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- Revenues Independent Energy 86% 86% 89% 85% Electric utility 13 13 11 15 Communications 1 1 -- -- ---- ---- ---- ---- 100% 100% 100% 100% ==== ==== ==== ==== Net Income/(Loss) Independent energy 61% 43 59% 35% Electric utility 54 79 62 74 Communications and other (15) (22) (21) (9) ---- ---- ---- ---- 100% 100% 100% 100% ==== ==== ==== ==== Net income from the independent energy group exceeded net income derived from our utility for the first time in the first quarter 2001. We expect that earnings growth from the independent energy group over the next few years will be driven primarily by our continued expansion in the independent power production segment. We also believe that continued strength in commodity prices and energy markets will provide the opportunity for strong results in our fuel marketing and oil and gas production operations. Our electric utility has continued to produce modest growth in revenue and earnings from the retail business over the past two years. We believe that this trend is stable and that, absent unplanned system outages, it will continue for the next several years due to the extension of our electric utility's rate freeze until January 1, 2005. The share of the utility's future earnings generated from wholesale off-system sales will depend on many factors, including native load growth, plant availability and commodity prices in the western markets. Although our communications business continues to significantly increase residential and business customers, we expect it will sustain approximately $10 million in net losses in 2001, with annual losses decreasing thereafter and profitability expected in the next three to four years. 16

The following business group and segment information includes intercompany eliminations with the exception of intercompany coal sales which are not eliminated in accordance with the provisions of SFAS No. 71 and the calculations of EBITDA: Independent Energy Group Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $487,188 $214,111 $1,715,759 $737,369 Expenses 355,716 208,510 1,622,635 720,753 ------- ------- --------- ------- Operating income $131,472 $5,601 $93,124 $16,616 Net income $19,475 $3,854 $44,431 $13,111 EBITDA $42,445 $7,056 $99,933 $26,400 EBITDA represents earnings before interest, income taxes, depreciation and amortization and any non-recurring or non-cash items. EBITDA is used by management and some investors as an indicator of a company's historical ability to service debt. Management believes that an increase in EBITDA is an indicator of improved ability to service existing debt, to sustain potential future increases in debt and to satisfy capital requirements. However, EBITDA is not intended to represent cash flows for the period, nor has it been presented as an alternative to either operating income, or as an indicator of operating performance or cash flows from operating, investing and financing activities, as determined by generally accepted accounting principles. EBITDA as presented may not be comparable to other similarly titled measures of other companies. The following is a summary of sales volumes of our coal, oil and natural gas production: Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- Tons of coal sold 818,000 793,000 3,075,000 3,146,000 Barrels of oil sold 99,000 79,000 354,000 316,000 Mcf of natural gas sold 1,006,000 716,000 3,564,000 2,799,000 Mcf equivalent sales 1,600,000 1,190,000 5,688,000 4,695,000 17

The following is a summary of average daily fuel marketing volumes: Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- Natural gas - MMBtus 866,000 630,300 920,000 500,000 Crude oil - barrels 37,000 44,000 43,000 25,300 Coal - tons 6,100 4,600 4,700 4,700 The independent energy business group's revenues increased 128 percent and 133 percent for the three and twelve month periods, respectively. Earnings of this group increased 405 percent and 239 percent for the three and twelve month periods, respectively. The revenue and earnings increase for the periods were a direct result of increased volumes, increased fuel and power prices related to gas and electricity shortages in the West Coast markets, and the closing of the Indeck Capital acquisition. Daily volumes of natural gas marketed increased 37 percent and 84 percent for the three and twelve month periods, respectively. In addition, the increase in the twelve month period was aided by the acquisition of Indeck Capital and the sale of our ownership interest in a power fund management company which resulted in a $3.7 million pre-tax gain. Coal Mining Segment - ------------------- Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $8,263 $8,095 $30,698 $31,413 Operating income $2,674 $3,314 $8,155 $12,886 Net income $2,066 $2,363 $6,405 $9,399 EBITDA $3,330 $3,801 $10,387 $14,580 A planned five-week overhaul of the Wyodak plant during the second quarter of 2000 resulted in lower coal sales and earnings for the current twelve month period compared to the prior year. Oil and Gas Segment - ------------------- Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $8,581 $3,962 $23,802 $14,031 Operating income $4,398 $1,330 $10,974 $4,821 Net income $2,956 $890 $7,047 $3,086 EBITDA $6,127 $2,096 $16,025 $7,685 18

Revenue and earnings of the oil and gas production business segment increased for the three and twelve month periods due to increases in gas volumes sold of 40 percent and 27 percent, respectively, while average gas prices were 3.6 times and 1.7 times higher than the same periods in the prior year, respectively. Barrels of oil sold increased 25 percent and 12 percent for the three and twelve month periods while prices remained comparable. The following is a summary of our estimated oil and gas reserves at March 31 determined using constant product prices at the end of the respective period. Estimates of economically recoverable reserves are based on a number of variables, which may differ from actual results. 2001 2000 ---- ---- Barrels of oil (in millions) 4.2 3.9 Bcf of natural gas 17.2 17.4 Total in Bcf equivalents 42.9 41.0 In addition to the reserves as of March 31, 2001 noted above, we announced during the first quarter 2001 a definitive agreement to purchase operating and non-operating interests in 74 gas and oil wells from Stewart Petroleum for approximately $10 million. The acquisition was closed early in the second quarter of 2001 and is expected to increase our proved reserves by approximately 10 billion cubic feet equivalent of which approximately 86 percent are natural gas. The acquisition is expected to increase our current production rates by approximately 10 percent. Fuel Marketing Segment - ---------------------- Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $452,299 $202,054 $1,603,712 $691,925 Operating income $25,188 $988 $48,203 $(919) Net income $15,559 $570 $28,975 $688 EBITDA $25,819 $1,105 $48,693 $4,312 Revenues and earnings increased primarily due to a significant increase in natural gas volumes marketed during the current three and twelve month periods while margins received also increased substantially. The significant increases can, in part, be attributed to the unusual market conditions in the western markets, which primarily stem from the natural gas and electricity shortages in California and may not recur in the future. However, we believe that the continued growth in demand for natural gas will create opportunities for us to continue to generate strong fuel marketing operating results in the future. 19

Independent Power Production Segment - ------------------------------------ Our independent power segment produced revenues of $18.0 million and $57.5 million for the three and twelve month periods ended March 31, 2001, respectively. Earnings for the same periods were $(1.1) million and $2.0 million, respectively. Results from this segment were not significant for the three and twelve month periods ended March 31, 2000. Current periods results stem from our acquisition of Indeck Capital in the third quarter of 2000. The net loss for the current three month period is due to credit reserves of $2.5 million being established to offset this segments' direct exposure to the volatile western markets. Early in the second quarter of 2001, we closed on the purchase of the Fountain Valley facility, a 240 megawatt generation facility located near Colorado Springs, Colorado, featuring six LM-6000 simple-cycle, gas-fired turbines. The facility is currently under construction and is expected to come on-line early in the third quarter of 2001. In addition, we obtained an 11-year contract with Public Service of Colorado to utilize the facility for peaking purposes. The contract is a tolling arrangement in which the Company assumes no fuel risk. Electric Utility Group - ---------------------- Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $70,580 $33,299 $210,589 $133,437 Operating income $28,664 $13,644 $83,228 $52,555 Net income $17,337 $7,198 $47,244 $27,611 EBITDA $33,167 $17,478 $98,983 $67,949 Electric utility revenues increased 112 percent and 58 percent for the three and twelve month periods ended March 31, 2000, respectively, compared to the same periods in the prior year. Earnings for the segment increased 141 percent and 71 percent over the same periods, respectively. The increase in revenues and earnings for the three and twelve month periods was primarily due to a 145 percent and a 91 percent increase in wholesale off-system sales at average prices that were seven times and four times higher than the average prices in the same periods of the prior year, respectively. The increase in off-system sales was driven by high spot market prices for energy since the middle of 2000, which enabled us to generate more energy from our combustion turbine facilities, including the Neil Simpson combustion turbine which we placed into commercial operation in June 2000. 20

Communications Group - -------------------- Three Months Ended Twelve Months Ended March 31 March 31 2001 2000 2001 2000 ---- ---- ---- ---- (in thousands) Revenue $3,925 $549 $11,065 $827 Operating expenses 7,697 2,712 25,160 6,289 ----- ----- ------ ----- Operating income $(3,772) $(2,163) $(14,095) $(5,462) Net income $(3,891) $(1,899) $(14,019) $(3,315) EBITDA $(1,436) $(1,466) $(6,874) $(3,011) As of March 31, 2001 our Communications business group is providing broadband services to approximately 10,000 residential and 1,000 business customers. Operating losses primarily attributable to increased interest, depreciation and operating expenses, are expected to continue as we proceed with completion of the network and increase the customer base. Liquidity and Capital Resources During the three and twelve month periods ended March 31, 2001, we generated sufficient cash flow from operations to meet our operating needs, to pay dividends on common and preferred stock, to pay long-term debt maturities and substantially increase our cash position over March 31, 2000. We continue to fund property additions primarily related to construction of additional electric generation facilities for our independent energy business group through a combination of operating cash flow, increased short-term debt and long-term non-recourse project financing. Investing and financing activities increased primarily due to short and long-term borrowings related to project financing. During the first quarter of 2001, the Company announced the public offering of 3 million shares of common stock with an option for the underwriters to purchase 450,000 additional shares. Credit Suisse First Boston, Lehman Brothers, CIBC World Markets and UBS Warburg acted as the managers of the underwriting syndicate. Early in the second quarter of 2001 the Company announced the offering price was set at $52 per share and all 3 million shares were sold with the underwriters exercising their over-allotment option to purchase an additional 383,000 shares. Net proceeds were approximately $165 million after commissions and expenses. The proceeds will be used to fund a portion of the expansion and construction costs related to certain power plant assets of the Company's independent energy group, to repay a portion of current indebtedness under revolving credit facilities, and for general corporate purposes. There have been no material changes in our forecasted changes in liquidity and capital requirements from those reported in Item 7 of our 2000 Annual Report on Form 10-K filed with the Securities Exchange Commission. 21
