Exhibit 99.02 UNAUDITED PRO FORMA FINANCIAL INFORMATION The following unaudited pro forma financial information adjusts the historical consolidated balance sheets and statements of income of NSP and WEC after giving effect to their proposed business combination transaction (the Transaction) to form Primergy and a new subsidiary structure. The unaudited pro forma combined condensed balance sheets at Dec. 31, 1995 give effect to the Transaction as if it had occurred on that date. The unaudited pro forma combined condensed statements of income for each of the three years in the period ended Dec. 31, 1995 give effect to the Transaction as if it had occurred at Jan. 1, 1993. These statements are prepared on the basis of accounting for the Transaction as a pooling of interests and are based on the assumptions set forth in the notes thereto. The following pro forma financial information has been prepared from, and should be read in conjunction with, the historical consolidated financial statements and related notes thereto of NSP and WEC. The following information is not necessarily indicative of the financial position or operating results that would have occurred had the Transaction been consummated on the date, or at the beginning of the periods, for which the Transaction is being given effect nor is it necessarily indicative of future operating results or financial position. Primergy Pro Forma Combined Condensed Information The pro forma financial information combines the historical financial statements of NSP and WEC after giving effect to the Transaction to form Primergy.

PRIMERGY CORPORATION NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS 1. The pro forma combined condensed financial statements reflect the conversion of each share of NSP common stock outstanding ($2.50 par value) into 1.626 shares of Primergy Common Stock ($.01 par value) and the continuation of each share of WEC Common Stock outstanding as one share of Primergy common stock ($.01 par value), as provided in the Merger Agreement. The pro forma combined condensed financial statements are presented as if the companies were combined during all periods included therein. NSP equivalent shares shown on the pro forma combined condensed income statements represent the pro forma equivalent of one share of NSP Common Stock calculated by multiplying the pro forma information by the conversion ratio of 1.626 shares of Primergy Common Stock for each share of NSP Common Stock. 2. The allocation between NSP and WEC and their customers of the estimated cost savings, resulting from the Transaction, net of the costs incurred to achieve such savings, will be subject to regulatory review and approval. Cost savings resulting from the Transaction are estimated to be approximately $2 billion over a 10-year period, net of transaction costs (including fees for financial advisors, attorneys, accountants, consultants, filings and printing) and net of costs to achieve the savings of approximately $30 million and $122 million, respectively. None of the estimated cost savings, the costs to achieve such savings, or the transaction costs have been reflected in the pro forma combined condensed financial statements. 3. Intercompany transactions (including purchased and exchanged power transactions) between NSP and WEC during the periods presented were not material and, accordingly, no pro forma adjustments were made to eliminate such transactions. 4. A pro forma adjustment has been made to conform the presentation of noncurrent deferred income taxes in the pro forma combined condensed balance sheet into one net amount. All other report presentation and accounting policy differences are immaterial and have not been adjusted in the pro forma combined condensed financial statements. 5. Certain reclassifications have been made to the 1994 and 1993 NSP financial statements to conform with the 1995 presentation. These reclassifications had no effect on net income or earnings per share.
