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 on 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 2001 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, 2002, December 31, 2001 and March 31, 2001, financial information and are of a normal recurring nature. The results of operations for the three and twelve months ended March 31, 2002, are not necessarily indicative of the results to be expected for the full year. (2) RECLASSIFICATIONS Certain 2001 amounts in the financial statements have been reclassified to conform to the 2002 presentation. These reclassifications did not have an effect on the Company's total stockholders' equity or net income as previously reported. (3) RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS In June 2001, the FASB issued Statement of Financial Accounting Standards No. 143, "Accounting for Asset Retirement Obligations" (SFAS 143). SFAS 143 requires that the fair value of a liability for an asset retirement obligation be recognized in the period in which it is incurred with the associated asset retirement costs being capitalized as part of the carrying amount of the long-lived asset. Over time, the liability is accreted to its present value each period and the capitalized cost is depreciated over the useful life of the related asset. Management expects to adopt SFAS 143 effective January 1, 2003 and is currently evaluating the effects adoption will have on the Company's consolidated financial statements. 6

(4) RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS In June 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 141, "Business Combinations," (SFAS 141) and No. 142, "Goodwill and Other Intangible Assets" (SFAS 142). The Company has adopted SFAS 141, which requires all business combinations initiated after June 30, 2001 to be accounted for using the purchase method of accounting. Under SFAS 142, goodwill and intangible assets with indefinite lives are no longer amortized but the carrying values are reviewed annually (or more frequently if impairment indicators arise) for impairment. If the carrying value exceeds the fair value, an impairment loss shall be recognized. A discounted cash flow approach was used to determine fair value of the Company's businesses for the purposes of testing for impairment. Intangible assets with a defined life will continue to be amortized over their useful lives (but with no maximum life). The Company adopted SFAS 142 on January 1, 2002. The pro forma effects of adopting SFAS No. 142 for the three and twelve month periods ended March 31, 2002 and 2001 are as follows (in thousands): Three Months Ended Twelve Months Ended March 31 March 31 2002 2001 2002 2001 ---- ---- ---- ---- Net income as reported $14,008 $32,050 $69,509 $75,623 Less: cumulative effect of change in accounting principle, net of tax 141 - 141 - ------- ------- ------- ------- Income excluding cumulative effect of change in accounting principle 13,867 32,050 69,368 75,623 Add: goodwill amortization, net of tax - 235 575 1,022 ------- ------- ------- ------- Net income excluding cumulative effect of change in accounting principle and goodwill amortization $13,867 $32,285 $69,943 $76,645 ======= ======= ======= ======= The cumulative effect adjustment recognized upon adoption of SFAS 142 was $0.1 million (after tax), which had only a nominal impact on earnings per share. The adjustment consisted of income from the write-off of negative goodwill from prior acquisitions in our Power Generation segment of $1.5 million, offset by a $1.3 million write-off for the impairment of goodwill in our coal marketing business (fuel marketing segment). The goodwill impairment was a result of changes in the criteria for the measurement of impairments from an undiscounted to a discounted cash flow method. If goodwill amortization had been discontinued effective January 1, 2001, net income would have been higher for the twelve month period ended March 31, 2002 and the three and twelve month periods ended March 31, 2001 by $0.6 million, or 2 cents per share, $0.2 million, or 1 cent per share, and $1.0 million, or 4 cents per share, respectively. 7

The substantial majority of the Company's goodwill and intangible assets are contained within the Power Generation segment. Changes to goodwill and intangible assets during the three month period ended March 31, 2002, including the effects of adopting SFAS No. 142, are as follows (in thousands): Goodwill Other Intangible Assets -------- ----------------------- Balance at December 31, 2001, net of accumulated amortization $29,950 $86,961 Change in accounting principle 235 - Additions - 9,504 Impairment of intangible asset - (417) Amortization expense - (1,021) ------- ------- Balance at March 31, 2002, net of accumulated amortization $30,185 $95,027 ======= ======= On March 31, 2002, intangible assets totaled $95.0 million, net of accumulated amortization of $6.1 million. Intangible assets are primarily related to site development fees and above-market long-term contracts, and all have definite lives over which they continue to be amortized. Amortization expense for intangible assets is expected to be approximately $5.1 million to $4.5 million for each year from 2003 to 2007. Intangible assets increased during the three month period ended March 31, 2002 as a result of a $9.5 million addition related to preliminary purchase allocations in the acquisition of additional ownership interest in the Harbor Cogeneration Facility (See Note 9). This intangible asset primarily relates to an above-market contract at the Facility. Under the provisions of Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" there was also a $0.4 million (pre tax) impairment loss of certain intangibles at the Company's coal marketing business (Fuel Marketing segment), as a result of the depressed coal market. The impairment loss is included in "Depreciation, depletion and amortization" on the accompanying Consolidated Statements of Income. In August 2001, the FASB issued SFAS 144. SFAS 144 supersedes FASB Statement 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" (SFAS 121) and the accounting and reporting provisions of Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations - Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions" (APB 30). SFAS 144 establishes a single accounting model for long-lived assets to be disposed of by sale as well as resolves implementation issues related to SFAS 121. The Company adopted SFAS 144 effective January 1, 2002. Adoption did not have a material impact on the Company's consolidated financial position, results of operations or cash flows. 8

(5) COMPREHENSIVE INCOME The following table presents the components of the Company's comprehensive income: Three Months Ended Twelve Months Ended March 31 March 31 2002 2001 2002 2001 ---- ---- ---- ---- (in thousands) Net income available for common stock $14,008 $32,050 $69,509 $75,623 Other comprehensive income: Unrealized gain (loss) on available- for-sale securities (219) 1,023 195 210 Fair value adjustment on derivatives designated as cash flow hedges 509 (9,953) 2,230 (9,953) ------- ------- ------- ------- Comprehensive income $14,298 $23,120 $71,934 $65,880 ======= ======= ======= ======= (6) CHANGES IN LONG-TERM DEBT AND NOTES PAYABLE On March 15, 2002, the Company closed on $135 million of senior secured financing for the Arapahoe and Valmont Facilities. These projects have a total of 210 megawatts in service and under construction and are located in the Denver, Colorado area. Proceeds from this financing were used to refinance $53.8 million of an existing seven-year senior secured term project-level facility, pay down approximately $50.0 million of short-term credit facility borrowings and approximately $31.2 million will be used for future project construction. At March 31, 2002, $114.3 million of the $135 million financing has been utilized. On January 4, 2002, the Company closed on a $50.0 million bridge credit agreement. The credit agreement supplements our revolving credit facilities in place at December 31, 2001 and has the same terms as those facilities with an expiration date of June 30, 2002. Outstanding borrowings under the agreement as of March 31, 2002 were $26.0 million. Other than the above transactions, the Company had no other material changes in its consolidated indebtedness, as reported in Notes 6 and 7 of the Company's 2001 Annual Report on Form 10-K. Our credit facilities contain certain restrictive covenants, including restrictions on the ability of certain subsidiaries with project level financings to upstream cash. The Company and its subsidiaries had complied with all the covenants at March 31, 2002. (7) 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, 2002, substantially all of the Company's operations and assets are located within the United States. The Company's operations are conducted through six business segments that include: Electric 9

group and segment, which supplies electric utility service to western South Dakota, northeastern Wyoming and southeastern Montana; Integrated 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; Power Generation, 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 2001 Annual Report on Form 10-K. In accordance with the provisions of SFAS No. 71, intercompany coal sales are not eliminated. 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) Quarter to Date March 31, 2002 Fuel marketing $211,911 $ 1,167 $ (218) Power production 32,082 - 5,671 Oil and gas 5,390 697 878 Mining 5,450 2,752 2,335 Electric 37,110 82 7,823 Communications 7,181 365 (2,227) Corporate - - (198) Intersegment eliminations - (2,313) - -------- -------- ------- Total $299,124 $ 2,750 $14,064 ======== ======== ======= External Inter-segment Operating Revenues Operating Revenues Net Income (loss) Quarter to Date March 31, 2001 Fuel marketing $452,299 $3,592 $15,559 Power production 18,045 - (1,106) Oil and gas 8,581 - 2,956 Mining 5,407 2,856 2,315 Electric 70,580 - 17,339 Communications 3,925 1,101 (3,891) Corporate - - (829) Intersegment eliminations - (4,693) (251) -------- ------ ------- Total $558,837 $2,856 $32,092 ======== ====== ======= 10

The Power Generation segment had a net addition to non working capital assets of approximately $52 million primarily related to ongoing construction of the expansions at the Las Vegas Cogeneration and Arapahoe facilities and the acquisition of additional ownership interest at the Harbor Cogeneration facility (Note 9). The Fuel Marketing segment acquired additional ownership interest in a pipeline company for $11.0 million (Note 9). 11

(8) RISK MANAGEMENT ACTIVITIES The Company actively manages its exposure to certain market risks as described in Note 2 of the Company's Annual Report on Form 10-K. Details of derivative and hedging activities included in the accompanying Consolidated Balance Sheets and Consolidated Statements of Income are as follows: Fuel Marketing Activities The Company's fuel marketing operations fall under the purview of Statement of Financial Accounting Standard No. 133 (SFAS 133), "Accounting for Derivative Instruments and Hedging Activities" and Emerging Issues Task Force Issue No. 98-10, "Accounting for Energy Trading and Risk Management Activities" (EITF 98-10). As such, these activities are accounted for under mark-to-market accounting.

(9) ACQUISITIONS On March 8, 2002, the Company acquired an additional 67 percent ownership interest in Millennium Pipeline Company L.P., which owns and operates a 200-mile pipeline. The pipeline has a capacity of approximately 65,000 barrels of oil per day, and transports imported crude oil from Beaumont, Texas to Longview, Texas, which is the transfer point to connecting carriers. The Company also acquired additional ownership interest in Millennium Terminal Company, L.P., which has 1.1 million barrels of crude oil storage connected to the Millennium Pipeline at the Oil Tanking terminal in Beaumont. The Millennium system is presently operating near capacity through shipper agreements. These acquisitions give the Company 100 percent ownership in the Millennium companies. Total cost of the acquisitions was $11.0 million and was funded through borrowings under short-term revolving credit facilities. 15

On March 15, 2002, the Company paid $25.7 million to acquire an additional 30 percent interest in the Harbor Cogeneration Facility (the Facility), a 98 megawatt gas-fired plant located in Wilmington, California. This acquisition was funded through borrowings under short-term revolving credit facilities and gives the Company an 83 percent ownership interest and voting control of the Facility. The Company's investments in these entities prior to the above acquisitions were accounted for under the equity method of accounting and included in Investments on the accompanying Consolidated Balance Sheets. Each of the above acquisitions gave the Company majority ownership and voting control of the respective entities, therefore, the Company now includes the accounts of each of the entities in its consolidated financial statements. The above acquisitions have been accounted for under the purchase method of accounting and, accordingly, the purchase prices have been allocated to the acquired assets and liabilities based on preliminary estimates of the fair values of the assets purchased and the liabilities assumed as of the date of acquisition. The estimated purchase price allocations are subject to adjustment, generally within one year of the date of the acquisition. The purchase prices and related acquisition costs exceeded the fair values assigned to net tangible assets by approximately $9.5 million, which was recorded as long-lived intangible assets. The impact of these acquisitions was not material in relation to the Company's results of operations. Consequently, pro forma information is not presented. 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 unregulated and regulated businesses have expanded significantly in recent years. Our integrated energy group, Black Hills Energy, Inc., produces and markets electric 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. Our electric utility, Black Hills Power, Inc., serves approximately 59,200 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 through Black Hills FiberCom, LLC. 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 2001 Annual Report on Form 10-K filed with the Securities and Exchange Commission. Our business strategy, industry outlooks, capital requirements and market risks as disclosed in that filing continue to be consistent with management's current expectations and assessments. 16

Results of Operations Consolidated Results 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 2002 2001 2002 2001 ---- ---- ---- ---- Revenues Integrated energy 86% 86% 84% 89% Electric utility 12 13 14 11 Communications 2 1 2 - --- --- --- --- 100% 100% 100% 100% === === === === Net Income/(Loss) Integrated energy 60% 61% 65% 59% Electric utility 56 54 51 62 Communications and other (16) (15) (16) (21) --- --- --- --- 100% 100% 100% 100% === === === === Three Months Ended March 31, 2002 Compared to Three Months Ended March 31, 2001. Consolidated earnings for the three month period ended March 31, 2002 were $14.0 million or $0.52 per share compared to $32.1 million or $1.37 per share in the same period of the prior year. Approximately $0.07 of the first quarter 2002 earnings per share was attributable to the collection of previously reserved amounts. The decrease in earnings was a result of substantial decreases in prevailing prices for natural gas, crude oil and wholesale electricity and in gross margins from natural gas marketing activities compared to the same period in 2001. Decreases in commodity prices also resulted in unrealized losses recognized through mark-to-market accounting at our Fuel Marketing segment having a negative impact on 2002 earnings compared to 2001. Unusual energy marketing conditions existed in the first quarter of 2001 stemming primarily from gas and electricity shortages in the West. Approximately half of the 2001 first quarter earnings were attributed to the unusual market conditions that existed at that time. Wholesale electricity average peak prices at Mid-Columbia were around $280 per megawatt-hour during the first quarter of 2001 compared to approximately $26 per megawatt-hour during the first quarter of 2002. Average spot gas prices in the West Coast region were approximately $13 per MMBtu in the first quarter of 2001 compared to $2.50 in the first quarter of 2002. While the above factors contributed negatively to earnings, we had an increase in the production of coal, oil and natural gas and our communications business unit showed a decrease in its net loss attributable to a substantial expansion of its customer base. Consolidated revenues for the three month period ended March 31, 2002 were $301.9 million compared to $561.7 million for the same period in 2001. The decrease in revenues was a result of the high energy commodity prices in 2001, slightly offset by increased revenue in the communications business unit and power production segment and increased production in coal, oil and gas. 17

Consolidated operating expenses for the three month period decreased from $500.1 million in 2001 to $271.7 million in 2002. The decrease was due to a substantial decrease in gas prices as discussed above. Depreciation, depletion and amortization expense increased from $11.9 million in 2001 to $16.8 million in 2002 primarily as a result of our increased investment in independent power generation. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Consolidated earnings for the twelve month period ended March 31, 2002 were $69.5 million or $2.63 per share compared to $75.6 million or $3.32 per share for the same period of the prior year. The decrease in earnings for the twelve month period ended March 31, 2002 was a result of the substantial decrease in prevailing prices for natural gas, crude oil and wholesale electricity and in the gross margins from natural gas marketing activities compared to the same period of 2001. Decreases in commodity prices also resulted in unrealized losses recognized through mark-to-market accounting at our Fuel Marketing segment having a negative impact on 2002 earnings compared to 2001. Volumes of natural gas marketed and off-system electric sales also declined due to a decrease in the demand of natural gas and electricity in the western markets compared to the prior year. We estimate approximately one-third of the earnings for the twelve month period ended March 31, 2001 could have been attributable to high prices of natural gas and electricity related to the volatile western markets during that period of time. Consolidated revenues for the twelve month period ended March 31, 2002 were $1.3 billion compared to $1.9 billion for the same period in 2001. The decrease in revenues was a result of the high energy commodity prices in late 2000 and 2001, slightly offset by increased revenue in the oil and gas segment from increased production, power production segment and communications business unit. Consolidated operating expenses for the twelve month period decreased from $1.8 billion in 2001 to $1.2 billion in 2002. The decrease was due to the substantial decrease in gas prices as discussed above. All other operating expenses increased due to our growth primarily in the power production segment and communications business unit. 18

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 and various measures of power generation: Three Months Ended Twelve Months Ended March 31 March 31 2002 2001 2002 2001 ---- ---- ---- ---- Fuel production: Tons of coal sold 1,001,000 818,000 3,702,000 3,075,000 Barrels of oil sold 114,300 99,000 461,000 354,000 Mcf of natural gas sold 1,287,800 1,006,000 4,901,000 3,564,000 Mcf equivalent sales 1,973,600 1,600,000 7,667,000 5,688,000 19

Earnings for the integrated energy group for the three months ended March 31, 2002 were $8.5 million compared to $18.9 million in the same period of the prior year. Earnings decreased primarily due to a substantial decline in energy prices. The power generation segment reported earnings growth attributed to additional generating capacity and the reporting of additional net income of $1.9 million relating to the collection of previously reserved amounts for California operations. A 23 percent increase in gas and oil production sales partially offset an earnings decrease in the oil and gas segment caused by lower prices. Earnings from coal mining operations increased slightly, as increases in production were offset by lower prices received. The fuel marketing segment's earnings decreased primarily due to a substantial decrease in margins received and unrealized losses recognized through mark-to-market accounting as a result of decreased commodity prices at March 31, 2002. The independent energy business group's revenues and expenses both decreased 47 percent for the three months ended March 31, 2002 compared to the same period in 2001. The decrease in revenue and expenses was a direct result of the substantial decline in fuel and power prices. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Earnings for the integrated energy group for the twelve months ended March 31, 2002 were $45.5 million compared to $43.1 million for the same period of the prior year, a 6 percent increase. Earnings increases in the power generation, oil and gas and coal mining segments were partially offset by a decrease in fuel marketing earnings. The power generation segment reported earnings growth attributed to additional generating capacity and the reporting of additional net income relating to the collection in 2002 of previously reserved amounts for California operations that were reserved for in the prior twelve month period. A 35 percent increase in gas and oil production sales contributed to the earnings increase. Earnings from coal mining operations increased 67 percent as a result of: a 20 percent increase in production offset by lower prices received, a coal contract settlement and a gain on the sale of mining equipment. The fuel marketing segments earnings decreased primarily due to a substantial decrease in margins received and unrealized losses recognized through mark-to-market accounting as a result of decreased commodity prices at March 31, 2002. These decreases were partially offset by a 13 20

percent increase in the daily volumes of natural gas marketed. The independent energy business group's revenues and expenses decreased 36 percent and 37 percent, respectively, for the twelve months ended March 31, 2002 compared to the same period in 2001. The decrease in revenue and expenses was a direct result of the substantial decline in fuel and power prices.

Fuel marketing is extremely competitive, and margins are typically very small. Three Months Ended March 31, 2002 Compared to Three Months Ended March 31, 2001. Revenues and earnings decreased primarily due to a substantial decline in commodity prices and margins received, as well as a 3 percent decrease in natural gas average daily volumes marketed. Unusual energy marketing conditions existed in the first quarter of 2001 stemming primarily from gas and electricity shortages in the West. Average spot gas prices in the West Coast region were approximately $13 per MMBtu in the first quarter of 2001 compared to $2.50 in the first quarter of 2002. As a result of changing commodity prices, earnings were impacted by unrealized losses recognized through mark-to-market accounting treatment. Unrealized mark-to-market gains/(losses) for the three month periods ended March 31, 2002 and 2001 were $(3.2) million and $5.0 million, respectively, resulting in a quarter over quarter earnings decrease of $(8.2) million. Earnings for the three months ended March 31, 2002, also include a $0.4 million pre-tax impairment of intangible assets in our coal marketing operations as a result of the depressed coal market and a $1.3 pre-tax impairment of goodwill recorded as a change in accounting principle resulting from the implementation of SFAS 142. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Revenues and earnings decreased 42 percent and 33 percent, respectively, primarily due to a substantial decrease in margins received and a decline in commodity prices, partially offset by a 13 percent increase in the daily volumes of natural gas marketed. Unusual energy marketing conditions existed for a substantial part of the twelve month period ended March 31, 2001, stemming primarily from gas and electricity shortages in the West. As a result of changing commodity prices, earnings were impacted by unrealized losses recognized through mark-to-market accounting treatment. Unrealized mark-to-market gains/(losses) for the twelve month periods ended March 31, 2002 and 2001 were $(5.1) million and $7.4 million, respectively, resulting in a year over year decrease of $(12.5) million. 21

Earnings for the twelve months ended March 31, 2002 also include a $0.4 million pre-tax impairment of intangible assets in our coal marketing operations as a result of the depressed coal market and a $1.3 million pre-tax impairment of goodwill recorded as a change in accounting principle resulting from the implementation of SFAS 142. Power Generation - ---------------- Three Months Ended Twelve Months Ended March 31 March 31 2002 2001 2002 2001 ---- ---- ---- ---- (in thousands) Revenue $32,082 $18,045 $108,331 $57,547 Operating income $15,281 $ 5,540 $ 37,196 $25,792 Net income (loss) $ 5,671 $(1,106) $ 8,353 $ 2,004 EBITDA $21,759 $ 7,168 $ 58,954 $24,828 Three Months Ended March 31, 2002 Compared to Three Months Ended March 31, 2001. Revenue, operating income and net income increased substantially for the three month period ended March 31, 2002 compared to the same period in 2001 attributed to additional generating capacity and additional earnings of $1.9 million in 2002 relating to the collection of previously reserved amounts for California operations that were reserved for in the prior period. As of March 31, 2002, we had 646 megawatts of independent power capacity in service compared to 250 megawatts at March 31, 2001. The increase in net income for the three month period ended March 31, 2002 was also benefited by approximately a $1.0 million after-tax adjustment for negative goodwill to reflect the impact of a change in accounting for goodwill in accordance with the adoption of Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" (SFAS 142) effective January 1, 2002. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Revenues nearly doubled and earnings more than quadrupled for the twelve months ended March 31, 2002, compared to the same period of the prior year, due to additional generating capacity, a full year of operations for this segment and the recording of certain non-recurring items. Our power generation segment began in the third quarter of 2000 with the acquisition of Indeck Capital. As of March 31, 2002, we had 646 megawatts of independent power capacity in service with an additional 364 megawatts under construction (including a 90 MW plant under a lease arrangement). Non-recurring items that affected earnings include: a $1.9 million after-tax benefit for the twelve month period ended March 31, 2002, relating to the collection of amounts previously reserved for in the prior period for exposure to the California market, a $1.0 million after-tax benefit for negative goodwill recorded in the twelve month period ended March 31, 2002, to reflect the impact of a change in accounting for goodwill in accordance with the adoption of SFAS 142, and a $4.4 million after-tax charge recorded in the twelve month period ended March 31, 2002, related to our exposure to Enron. 22

Revenue and earnings of the oil and gas production business segment decreased for the three month period ended March 31, 2002, compared to the same period in 2001 due to a 43 percent decrease in the average price received partially offset by a 23 percent increase in production volumes. The increase in production was primarily related to the acquisition of 74 gas and oil wells from Stewart Petroleum Corporation of Denver, Colorado in the second quarter of 2001. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Revenue and earnings of the oil and gas production business segment increased 24 percent and 15 percent, respectively for the twelve month period ended March 31, 2002, compared to the same period in the prior year as a result of a 35 percent increase in production volumes partially offset by an 8 percent decrease in the average price received. The increase in production volumes was primarily due to development drilling and the acquisition of 74 gas and oil wells from Stewart Petroleum Corporation of Denver, Colorado in the second quarter of 2001.

Three Months Ended March 31, 2002 Compared to Three Months Ended March 31, 2001. Revenue and net income from our coal mining segment were relatively stable for the three month period ended March 31, 2002, compared to the same period in 2001. A 22 percent increase in tons of coal sold was offset by lower prices received. Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Revenue increased slightly for the twelve month period ended March 31, 2002, compared to the same period in the prior year due to a 20 percent increase in tons of coal sold, partially offset by lower prices received. Earnings increased $4.6 million as a result of a coal contract settlement, a gain on the sale of mining equipment and the increase in tons of coal sold. Tons of coal sold increased primarily due to the commencement of sales through our train load-out facility. In 2001, we reached a settlement of ongoing litigation with PacifiCorp concerning rights and obligations under a coal supply agreement under which PacifiCorp purchased coal from our coal mine to meet the coal requirements of the Wyodak Power Plant. As a result of this settlement, we recognized $5.6 million pre-tax, non-operating income in the twelve month period ended March 31, 2002. In addition, we sold a conveyor system which resulted in a $2.6 million pre-tax gain.

Revenue, operating expenses and net income decreased 47 percent, 45 percent and 55 percent, respectively for the three month period ended March 31, 2002 compared to the same period in the prior year primarily due to a 37 percent decrease in off-system electric megawatt-hour sales and an 81 percent decrease in the average price per megawatt-hour sold of off-system sales. Firm residential and contracted electricity sales increased, but were offset by a decline in industrial sales due to the closing of the Homestake Gold Mine at year-end 2001. 24

Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. Revenue, operating expenses and net income decreased 15 percent, 14 percent and 24 percent, respectively for the twelve month period ended March 31, 2002, compared to the same period in the prior year primarily due to a 40 percent decrease in the average price per megawatt-hour sold for off-system sales partially offset by a 4 percent increase in off-system electric megawatt-hour sales. The average price received for off-system sales for the twelve month period ended March 31, 2002, was approximately $60 per megawatt-hour compared to $99 per megawatt-hour for the same period in the prior year.

Intersegment revenue is primarily revenue from our information services company derived from providing services to our other business segments. March 31 December 31 2002 2001 2001 2000 ---- ---- ---- ---- Business customers 2,600 980 2,250 650 Residential customers 17,550 10,060 15,660 8,370 Three Months Ended March 31, 2002 Compared to Three Months Ended March 31, 2001. The communications business group reported EBITDA positive results in the first quarter of 2002. The net loss for the three month period ended March 31, 2002 was $(2.2) million, compared to $(3.9) million in 2001. The performance improvement is due largely to a substantial increase in revenue as a result of a larger customer base, partially offset by increased costs of sales and administrative expenses. The total number of customers exceeded 20,000 at the end of March 2002 - a 13 percent increase over the customer base at December 31, 2001 and an 82 percent increase compared to March 31, 2001. 25

Twelve Months Ended March 31, 2002 Compared to Twelve Months Ended March 31, 2001. The net loss for the twelve month period ended March 31, 2002 was $(10.6) million, compared to $(13.8) million for the same period in the prior year. The performance improvement was the result of an 82 percent increase in our customer base offset by increased cost of sales, administrative expenses, reserves for inventory and carrier billings and increased interest expense. We expect our communications group will sustain approximately $6.5 million in net losses in calendar year 2002, with annual losses decreasing thereafter and profitability expected by 2004. The recovery of capital investment and future profitability are dependent primarily on our ability to attract new customers. If we are unable to attract additional customers or technological advances make our network obsolete, we could have a material write-down of assets. Critical Accounting Policies Goodwill and Other Intangible Assets As required, on January 1, 2002 we adopted the provisions of Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" (SFAS 142). Under SFAS 142, goodwill and intangible assets with indefinite lives are no longer amortized but the carrying values are reviewed annually (or more frequently if impairment indicators arise) for impairment. Intangible assets with a defined life will continue to be amortized over their useful lives (but with no maximum). Initial adoption of SFAS 142 did not have a material impact on our financial position or results of operations. Adoption of SFAS 142 provisions for non-amortization of goodwill and indefinite lived intangibles will impact our future earnings results. Results for the three months ended March 31, 2002 were approximately $0.2 million, or 1 cent per share, higher than the comparable period in 2001 due to non-amortization of goodwill. Other than the above, there have been no material changes in our critical accounting policies from those reported in our 2001 Annual Report on Form 10-K filed with the Securities Exchange Commission. For more information on our critical accounting policies, see Part II, Item 7 in our 2001 Annual Report on Form 10-K. Liquidity and Capital Resources Cash Flow Activities During the three month period ended March 31, 2002, 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 to fund a material amount of our property additions. We continue to fund property and investment additions primarily related to construction of additional electric generation facilities for our integrated energy business group through a combination of operating cash flow, increased short-term debt and long-term non-recourse project financing. Cash flows from operations decreased $39.6 million for the three month period ended March 31, 2002 compared to the same period in the prior year primarily due to the decrease in net income and working capital. 26

On March 8, 2002, we acquired an additional 67 percent interest in Millennium Pipeline Company, L.P., which owns and operates a 200-mile pipeline and an additional ownership interest in Millenium Terminal Company, L.P., which has 1.1 million barrels of crude oil storage connected to the Millennium Pipeline at the Oil Tanking terminal in Beaumont, Texas. Total cost of the acquisition was $11.0 million and was funded through borrowings under short-term revolving credit facilities. On March 15, 2002, we acquired an additional 30 percent interest in the Harbor Cogeneration Facility, a 98 megawatt gas-fired plant located in Wilmington, California for $25.7 million. This acquisition was also funded through borrowings under short-term revolving credit facilities. On March 15, 2002, we closed on $135 million of senior secured financing for the Arapahoe and Valmont facilities, 210 megawatts in service and under construction in the Denver, Colorado area. Proceeds from this financing were used to refinance $53.8 million of an existing seven-year secured term project-level facility, pay down approximately $50.0 million of short-term credit facility borrowings and approximately $31.2 million will be used for future project construction. In addition, during the first quarter of 2002, we completed a $50.0 million bridge credit agreement. The credit agreement supplements our revolving credit facilities and has the same terms as those facilities with an expiration date of June 30, 2002. Dividends Dividends paid on our common stock totaled $0.29 per share in the first quarter of 2002. This reflects a 3.6 percent increase approved by our board of directors in January 2002 from $0.28 per share in the first quarter of 2001. Dividends were paid out of current earnings. The determination of the amount of future cash dividends, if any, to be declared and paid will depend upon, among other things, our financial condition, funds from operations, the level of our capital expenditures, restrictions under our credit facilities and our future business prospects. Short-Term Liquidity and Financing Transactions Our principal sources of short-term liquidity are our revolving bank facilities and cash provided by operations. As of March 31, 2002 we had $66.2 million of cash and $450 million of bank facilities. The bank facilities consist of a $50 million bridge facility due June 30, 2002, a $200 million facility due August 27, 2002 and a $200 million facility due August 27, 2004. These bank facilities can be used to fund our working capital needs, for general corporate purposes and to provide liquidity for a commercial paper program if implemented. At March 31, 2002, we had $389 million of bank borrowings outstanding under these facilities. The corresponding amount outstanding at April 30, 2002 was $393 million. After inclusion of applicable letters of credit, the remaining borrowing capacity under the bank facilities was $27 million and $23 million at March 31, 2002 and April 30, 2002, respectively. The above bank facilities include covenants that are common in such arrangements. Such covenants include a consolidated net worth in an amount of not less than the sum of $375 million and 50 percent of the aggregate consolidated net income beginning June 30, 2001; a recourse leverage ratio not to exceed 0.65 to 1.00; an interest coverage ratio of not less than 3.00 to 1.00; and a credit rating of at least "BBB-" from Standard & Poor's or" Baa3" from Moody's Investor Service. If these covenants are violated, it would be considered an event of default and the 27

lender has the right to terminate the remaining commitment and accelerate the principal and interest outstanding to become immediately due. In addition, certain of our interest rate swap agreements include cross-default provisions. These provisions would allow the counterparty the right to terminate the swap agreement and liquidate at a prevailing market rate, in the event of default. Our consolidated net worth was $525.7 million at March 31, 2002. The long-term debt component of our capital structure at March 31, 2002 was 49 percent and our total debt leverage (long-term debt and short-term debt) was 63 percent. In addition, Enserco Energy, Inc., our gas marketing unit, has a $75 million uncommitted, discretionary line of credit to provide support for the purchase of natural gas. We provide no guarantee to the lender under this facility. At March 31, 2002, there were outstanding letters of credit issued under the facility of $43.8 million with no borrowing balances on the facility. Similarly, Black Hills Energy Resources, Inc., our oil marketing unit, has a $25 million uncommitted, discretionary credit facility. This line of credit provides credit support for the purchases of crude oil by Black Hills Energy Resources. We provide no guarantee to the lender under this facility. At March 31, 2002, Black Hills Energy Resources had letters of credit outstanding of $21.1 million and no balance outstanding on its overdraft line. Black Hills Coal Network, Inc. has a $5.5 million uncommitted, discretionary line of credit to provide support for the purchase of coal. At March 31, 2002 there were outstanding borrowings on the facility of $0.3 million and outstanding letters of credit issued in the amount of $0.8 million. Based upon our expected cash flows from operations, expected project financings for the year, credit facility capacity, and projected cash needs in the near term, we currently believe we have sufficient capital to fund all requirements to July 2002 and anticipate that we will be able to obtain additional financing to fund future requirements. We are currently seeking long-term project-level non-recourse financing in the range of $200-$220 million for the Las Vegas Project, a 277 megawatt gas-fired generation complex located in North Las Vegas, Nevada prior to June 30, 2002. Total project costs are estimated to be $330 million of which approximately $269 million was expended as of March 31, 2002 and was funded with short-term credit facility borrowings. We are in the early stages of planning an $80-$100 million first mortgage bond offering at our Electric Utility business segment and anticipate renewing our $200 million credit facility that expires in August 2002. Completion of these financings will substantially improve our liquidity. Our ability to obtain additional financing will depend upon a number of factors, including our future performance and financial results and capital market conditions. We cannot be sure that we will be able to raise additional capital on reasonable terms or at all. There have been no other material changes in our forecasted changes in liquidity and capital requirements from those reported in Item 7 of our 2001 Annual Report on Form 10-K filed with the Securities Exchange Commission. 28

Forward Looking Statements The above information includes "forward-looking statements" as defined by the Securities and Exchange Commission. These statements concern the Company's plans, expectations and objectives for future operations. All statements, other than statements of historical facts, included above that address activities, events or developments that the Company expects, believes or anticipates will or may occur in the future are forward-looking statements. The words believe, intend, anticipate, estimate, aim, project and similar expressions are also intended to identify forward-looking statements. These forward-looking statements may include, among others, such things as expansion and growth of the Company's business and operations; future financial performance; future acquisition and development of power plants; future production of coal, oil and natural gas; reserve estimates; future communications customers; and business strategy. These forward-looking statements are based on assumptions which the Company believes are reasonable based on current expectations and projections about future events and industry conditions and trends affecting the Company's business. However, whether actual results and developments will conform to the Company's expectations and predictions is subject to a number of risks and uncertainties which could cause actual results to differ materially from those contained in the forward-looking statements, including the following factors: prevailing governmental policies and regulatory actions with respect to allowed rates of return, industry and rate structure, acquisition and disposal of assets and facilities, operation and construction of plant facilities, recovery of purchased power and other capital investments, and present or prospective wholesale and retail competition; changes in and compliance with environmental and safety laws and policies; weather conditions; population growth and demographic patterns; competition for retail and wholesale customers; pricing and transportation of commodities; market demand, including structural market changes; changes in tax rates or policies or in rates of inflation; changes in project costs; unanticipated changes in operating expenses or capital expenditures; capital market conditions; counterparty credit risk; technological advances; competition for new energy development opportunities; legal and administrative proceedings that influence the Company's business and profitability; and unanticipated developments in the western power markets, including unanticipated governmental intervention, deterioration in the financial condition of counterparties, default on amounts due, adverse changes in current or future litigation and adverse changes in the tariffs of the California Independent System Operator Corporation. Any such forward-looking statements should be considered in conjunction with Black Hills Corporation's most recent annual report on Form 10-K and its interim quarterly reports on Form 10-Q on file with the Securities and Exchange Commission. New factors that could cause actual results to differ materially from those described in forward-looking statements emerge from time to time, and it is not possible for the Company to predict all such factors, or to the extent to which any such factor or combination of factors may cause actual results to differ from those contained in any forward-looking statement. The Company assumes no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events, or otherwise. ITEM 3.
