EXHIBIT 99 UNAUDITED PROFORMA COMBINED CONDENSED FINANCIAL INFORMATION The following unaudited pro forma combined condensed balance sheet at December 31, 1999 gives effect to the NCE/NSP Merger as if it had occurred at December 31, 1999. The unaudited pro forma combined condensed statements of income for each of the three years in the period ended December 31, 1999 give effect to the NCE/NSP Merger as if it had occurred on January 1, 1997. These statements are prepared on the basis of accounting as required under a pooling of interests and do not reflect any cost savings anticipated by management as a result of the NCE/NSP Merger. Accordingly, the pro forma information is not necessarily indicative of the financial position or results of operations that would have occurred had the NCE/NSP Merger been consummated for the periods for which it is given effect, nor is it necessarily indicative of future operating results or financial condition. 147 Unaudited Pro Forma Combined Condensed Statement of Income Reflecting Completion of the NCE/NSP Merger Year ended December 31, 1999 (Thousands of Dollars, Except per Share Data) Northern New Century Reporting States Power Energies Adjustments Pro Forma Pro Forma (as Reported) (as Reported) (Note 2) Adjustments Combined ------------- ------------- ----------- ----------- ---------- Operating revenues: Electric....................................... $ 2,397,096 $ 2,527,341 $ (74) $ $4,924,363 Gas............................................ 471,915 764,943 (95,429) 1,141,429 Nonregulated and other revenues................ - 83,146 608,342 691,488 Earnings from equity investments............... - - 112,124 112,124 ------------- ------------- ----------- ----------- ---------- Total operating revenues.................... 2,869,011 3,375,430 624,963 6,869,404 Operating expenses: Electric fuel and purchased power.............. 773,680 1,185,232 - 1,958,912 Cost of gas sold and transported............... 278,240 485,107 (79,892) 683,455 Other operation and maintenance................ 768,169 538,967 90,989 1,398,125 Depreciation and amortization.................. 355,704 280,913 (9,063) 627,554 Taxes other than income taxes.................. 222,446 137,259 (2,034) 357,671 Income taxes - utility......................... 127,293 - (127,293) - Nonregulated operating expenses................ - 106,264 514,866 621,130 ------------- ------------- ----------- ----------- ---------- Total operating expenses.................... 2,525,532 2,733,742 387,573 5,646,847 Operating income................................ 343,479 641,688 237,390 1,222,557 Other income (expense): Income from nonregulated businesses before interest and taxes............................ 65,376 - (65,376) - Equity earnings from unconsolidated subsidiaries.................................. - 44,265 (44,265) - Other income (deductions) - net................

The unaudited pro forma combined condensed financial statements reflect the conversion of each share of NCE common stock, par value $1.00 per share, into 1.55 share of common stock of the combined company and the continuation of each share of NSP common stock, par value $2.50 per share, as one share of common stock of the combined company ($2.50 par value), as provided in the NCE/NSP Merger Agreement. The unaudited pro forma combined condensed financial statements are presented as if the companies were combined during all periods included therein. 2. The unaudited pro forma combined condensed income statements reflect certain reclassifications to conform the presentation of operating results. These reporting adjustments include: (a) separate presentation of nonregulated revenues and equity earnings in operating revenues; (b) separate presentation of all nonregulated expenses, including project write-downs, in operating expenses; (c) presentation of nonregulated interest and other income, including gains for project sales, in other income (deductions) - net; and (d) presentation of all income taxes (regulated and nonregulated) on a single line before arriving at net income. 3. The unaudited pro forma combined condensed balance sheet at December 31, 1999 reflects reporting adjustments to conform the presentation of: (a) investments and deferred charges (in other assets); (b) nonregulated property (in property, plant and equipment); and (c) construction work in progress (in other property, plant and equipment). 4. The allocation of the estimated costs savings resulting from the merger to NCE, NSP and their customers, net of the costs incurred to achieve such savings, will be subject to regulatory review and approval. At the time the merger agreement was signed, cost savings resulting from the merger were estimated to be approximately $1.1 billion over a ten-year period, net of transaction costs (including fees for financial advisors, attorneys, accountants, filings and printing) and net of costs to achieve the savings. Nonrecurring costs directly attributable to the NCE/NSP Merger are being deferred and total approximately $45 million as of December 31, 1999. Assuming the business combination is accounted for as a pooling-of- interests, these costs will be expensed upon the consummation of the NCE/NSP Merger. The unaudited pro forma combined condensed statements of income do not reflect any of these costs. The unaudited pro forma combined condensed balance sheet has been adjusted to reflect a write-off of the deferred costs and a related reduction of retained earnings. 5. Intercompany transactions (including purchased and exchanged power transactions) between NCE and NSP during the periods presented were not material and, accordingly, no pro forma adjustments were made to eliminate such transactions. 152
