1 EXHIBIT 99.1 PRO FORMA COMBINED CONSOLIDATED FINANCIAL INFORMATION The following unaudited pro forma combined condensed consolidated balance sheet combines the consolidated historical balance sheets of Peoples Heritage Financial Group, Inc. ("Peoples Heritage") and Banknorth Group, Inc. ("Banknorth"), assuming the merger of Banknorth with and into Peoples Heritage was consummated as of December 31, 1999 on a pooling of interests accounting basis, and the following unaudited pro forma combined condensed consolidated statements of operations present the combined consolidated statements of operations of Peoples Heritage and Banknorth assuming the merger was consummated as of the beginning of the indicated periods. Certain insignificant reclassifications have been reflected in the pro forma information to conform statement presentations. The effect of an expected reorganization and restructuring charge in connection with the merger has been reflected in the pro forma combined condensed consolidated balance sheet; however, because the reorganization and restructuring charge is nonrecurring, it has not been reflected in the pro forma combined condensed consolidated statements of operations. The pro forma financial data does not reflect cost savings, revenue enhancements and other operating synergies which are expected to be realized after the merger is completed. The pro forma information presented is not necessarily indicative of the results of operations or the combined financial position that would have resulted had the merger been consummated at December 31, 1999 or at the beginning of the periods indicated, nor is it necessarily indicative of the results of operations in future periods or the future financial position of the combined entities. The pro forma information should be read in conjunction with the historical consolidated financial statements of Peoples Heritage and Banknorth, including the related notes. 2 PRO FORMA COMBINED CONDENSED CONSOLIDATED BALANCE SHEET PEOPLES HERITAGE AND BANKNORTH DECEMBER 31, 1999 (Unaudited) (In Thousands) Peoples Pro Forma Heritage Banknorth Adjustments Combined -------- --------- ----------- -------- ASSETS Cash and due from banks $ 398,759 $ 148,057 $ -- $ 546,816 Federal funds sold and other short-term investments 203,789 25,790 -- 229,579 Securities available for sale, at market value 5,161,009 1,155,022 -- 6,316,031 Securities held to maturity 541,332 15,819 -- 557,151 Loans and leases held for sale 67,220 15,098 -- 82,318 Loans and leases 6,844,659 3,009,997 -- 9,854,656 Less: Allowance for loan and lease losses 107,871 47,177 -- 155,048 ------------ ------------ ------------ ------------ Net loans and leases 6,736,788 2,962,820 -- 9,699,608 Premises and equipment 141,739 50,801 -- 192,540 Goodwill and other intangibles 113,264 71,117 -- 184,381 Mortgage servicing rights 46,829 5,895 -- 52,724 Bank owned life insurance 228,423 60,360 288,783 Other assets 280,376 77,957 -- 358,333 ------------ ------------ ------------ ------------ Total assets $ 13,919,528 $ 4,588,736 $ -- $ 18,508,264 ============ ------------ ============ ============ LIABILITIES AND SHAREHOLDERS' EQUITY Deposits: Interest-bearing $ 6,629,847 $ 3,085,092 $ -- $ 9,714,939 Non-interest bearing 1,311,112 510,652 -- 1,821,764 Brokered deposits 173,798 -- -- 173,798 ------------ ------------ ------------ ------------ Total deposits 8,114,757 3,595,744 -- 11,710,501 ------------ ------------ ------------ ------------ Borrowings from the Federal Home Loan Bank of Boston 3,667,399 330,420 -- 3,997,819 Federal funds purchased and securities sold under repurchase agreements 1,089,316 213,505 -- 1,302,821 Other borrowings 31,849 34,989 -- 66,838 Other liabilities 96,455 42,781 30,972(1) 170,208 ------------ ------------ ------------ ------------ Total liabilities 12,999,776 4,217,439 30,972(1) 17,248,187 ------------ ------------ ------------ ------------ Corporation-obligated, mandatorily redeemable securities of subsidiary trust 68,775 30,000 -- 98,775 ------------ ------------ ------------ ------------ Shareholders' equity: Preferred Stock -- -- -- -- Common Stock: Peoples Heritage 1,066 -- 428(2) 1,494 Banknorth -- 23,548 (23,548)(2) -- Paid-in capital 509,009 85,396 19,543(2) 613,948 Retained earnings 530,002 257,236 (30,972)(1) 756,266 Unamortized employee restricted stock -- (992) -- (992) Unearned compensation (1,690) (69) -- (1,759) Accumulated other comprehensive income: Net unrealized loss on securities available for (105,149) (20,245) -- (125,394) sale Treasury stock, at cost (82,261) (3,577) 3,577(2) (82,261) ------------ ------------ ------------ ------------ Total shareholders' equity 850,977 341,297 (30,972)(1) 1,161,302 ------------ ------------ ------------ ------------ Total liabilities and shareholders' equity $ 13,919,528 $ 4,588,736 $ -- $ 18,508,264 ============ ============ ============ ============ 2 3 Notes to Pro Forma Combined Condensed Consolidated Balanced Sheet (1) Reflects an estimated $31 million, net of taxes, of reorganization and restructuring charges related to the merger. Additionally, in the first quarter of 2000, Peoples Heritage recorded $1 million, net of taxes, of special charges related to branch closings and Banknorth recorded $2 million, net of taxes, of special charges related to write-downs of a facility held for sale and auto lease residuals. In the second quarter of 2000, Peoples Heritage also expects to record approximately $10 million, net of taxes, in securities losses to restructure the combined investment portfolio. These items are not included in the above pro forma financial statements. (2) Reflects the par value of the Peoples Heritage common stock to be issued in exchange for Banknorth common stock in connection with the merger, with related adjustments to paid-in capital. The Peoples Heritage common stock to be issued in connection with the merger was calculated by multiplying the number of outstanding shares of Banknorth common stock as of December 31, 1999 by the 1.825 exchange ratio and adding the number of shares of Peoples Heritage common stock issuable or potentially issuable prior to the effective time of the merger, based on the 1.825 exchange ratio, with respect to the Banknorth common stock equivalents which were outstanding on such date. 3 4 PRO FORMA COMBINED CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS PEOPLES HERITAGE AND BANKNORTH YEAR ENDED DECEMBER 31, 1999 (Unaudited) (In Thousands, Except Share Data) Peoples Pro Forma Heritage Banknorth Combined(1) -------- --------- ----------- Interest and dividend income: Interest and fees on loans and leases $ 579,196 $ 247,369 $ 826,565 Interest and dividends on securities 328,739 72,215 400,954 ------------ ------------ ------------ Total interest and dividend income 907,935 319,584 1,227,519 ------------ ------------ ------------ Interest expense: Interest on deposits 252,195 121,331 373,526 Interest on borrowed funds 209,493 20,271 229,764 ------------ ------------ ------------ Total interest expense 461,688 141,602 603,290 ------------ ------------ ------------ Net interest income 446,247 177,982 624,229 Provision for loan and lease losses 14,100 9,475 23,575 ------------ ------------ ------------ Net interest income after provision for loan losses 432,147 168,507 600,654 ------------ ------------ ------------ Noninterest income: Customer services 53,402 18,842 72,244 Mortgage banking services 16,342 4,081 20,423 Trust and investment advisory services 19,923 19,455 39,378 Insurance commissions 20,289 -- 20,289 Net securities gains 281 374 655 Bank owned life insurance income 11,479 2,654 14,133 Bank owned life insurance claim -- 1,389 1,389 Other noninterest income 7,472 5,733 13,205 ------------ ------------ ------------ 129,188 52,528 181,716 ------------ ------------ ------------ Noninterest expenses: Salaries and employee benefits 163,621 67,879 231,500 Data processing 28,043 6,758 34,801 Occupancy 27,278 12,048 39,326 Equipment 21,068 10,309 31,377 Amortization of goodwill and deposit premiums 11,778 8,864 20,642 Distributions on securities of subsidiary trust 6,678 3,156 9,834 Advertising and marketing 9,456 4,716 14,172 Special charges 29,346 (1,344) 28,002 Other noninterest expenses 49,606 30,554 80,160 ------------ ------------ ------------ 346,874 142,940 489,814 ------------ ------------ ------------ Income before income tax expense 214,461 78,095 292,556 Income tax expense 72,039 23,559 95,598 ------------ ------------ ------------ Net income $ 142,422 $ 54,536 $ 196,958 ============ ============ ============ Basic earnings per share $ 1.38 $ 2.33 $ 1.35 ============ ============ ============ Diluted earnings per share $ 1.37 $ 2.30 $ 1.34 ============ ============ ============ Average common shares -

The cost savings, revenue enhancements and other operating synergies are expected to be achieved in various amounts at various times during the periods subsequent to consummation of the merger and not ratably over or at the beginning or end of such periods. No adjustment has been reflected in the pro forma combined statements of operations for the anticipated cost savings, revenue enhancements and other operating synergies. For the reasons noted above, it should not be assumed that the dilution in Peoples Heritage earnings per share reflected in the pro forma combined condensed consolidated statements of operations will represent actual dilution with respect to the merger. 7
