1 EXHIBIT 99.1 UNAUDITED PRO FORMA FINANCIAL DATA In March 1999, NTL acquired Diamond under the terms of the Diamond acquisition agreement in exchange for NTL's common stock. In December 1998, NTL acquired EGT in exchange for NTL's cash and preferred stock. In October 1998, NTL completed its acquisition of Comcast UK Cable Partners Limited in exchange for NTL's common stock. On June 16, 1998, NTL agreed to acquire substantially all of the operations of ComTel in a two-part transaction that was completed in September 1998 in exchange for approximately Pound Sterling 550 million. The cash portion of the purchase price was financed using funds available under NTL's credit facility. The amounts borrowed under the credit facility were repaid with most of the proceeds from the issuance of our 11 1/2% notes and our 12 3/8% notes in November 1998. The unaudited pro forma financial data presented herein give effect to the completed acquisitions of Partners, ComTel and EGT, and give further effect to the subsequent acquisition of Diamond. The pro forma financial data is based on the historical financial statements of Partners, ComTel, EGT, Diamond and NTL. The balance sheet data reflects the translation of all Pound Sterling denominated amounts at the December 31, 1998 rate of $1.6595 = Pound Sterling 1.00. The statements of operations data reflects the translation of all Pound Sterling denominated amounts at the average rate for the year ended December 31, 1998 of $1.6571 = Pound Sterling 1.00. The acquisitions have been accounted for in the pro forma financial data using the purchase method of accounting. Accordingly, the assets acquired and liabilities assumed have been recorded at their estimated fair values, which are subject to further adjustment based upon appraisals and other analyses. Management of NTL does not currently expect future adjustments from these analyses, if any, to be material to the unaudited pro forma financial statements. The pro forma financial statements do not give effect to the sale in January 1999 of NTL 5 1/4% preferred stock and warrants to Microsoft for $500 million. Under the terms of the Diamond indentures governing the terms of the Diamond notes, the share exchange in the Diamond acquisition constituted a "Change of Control". In general, upon the occurrence of a change of control, each holder of the Diamond notes has the right to require Diamond to repurchase the Diamond notes in cash at a purchase price equal to 101% of the accreted value or principal amount, as applicable. The pro forma financial statements do not give effect to the repurchase, if any, of the Diamond notes. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 1998 give effect to the acquisitions as if they had been consummated on January 1, 1998. The unaudited pro forma condensed combined balance sheet as of December 31, 1998 gives effect to the acquisition of Diamond as if it had been consummated on December 31, 1998. Partners owned a 27.5% interest (the "Birmingham Cable Equity Interest") in Birmingham Cable Corporation Limited and currently owns a 50% interest (the "Cable London Equity Interest" and, together with the Birmingham Cable Equity Interest, the "Equity Interests") in Cable London PLC ("Cable London"). Partners accounts for the Equity Interests using the equity method. The following pro forma financial data give effect to the issuance of 0.3745 shares of NTL common stock for each Partners common share and the sale of the Birmingham Cable Equity Interest to TeleWest Communications plc prior to the acquisition of Partners by NTL. The TeleWest agreement provides that at any time during the shoot-out period, Partners may give notice to TeleWest of an offer to sell to TeleWest the Cable London Equity Interest and related assets for the cash sum specified in the offer notice. If Partners fails to give the offer notice prior to the end of the shoot-out period, Partners will be deemed to have delivered an offer notice for a sum equal to Pound Sterling 100 million. TeleWest will have 30 days in which to accept or decline the offer. If TeleWest accepts the offer, Partners will sell to TeleWest the Cable London Equity Interest and related assets at the 2 sum specified in the offer notice. If TeleWest declines the offer, TeleWest will sell to Partners all of the shares in the capital of Cable London owned by TeleWest at the sum specified in the offer notice. The unaudited pro forma financial statements do not give effect to the sale of the Cable London Equity Interest to TeleWest or Partners' purchase of TeleWest's shares in the capital of Cable London, as management is currently unable to determine the probable outcome of the "shoot-out" procedure. The effect of the sale of the Cable London Equity Interest by Partners would be to eliminate Partners' investment in Cable London and increase cash by the amount of the proceeds. The effect of Partners' purchase of all of TeleWest's shares in the capital of Cable London would be to reduce Partners' cash and increase the amount of Partners' investment in Cable London. The pro forma adjustments are based upon available information and assumptions that the management of NTL believes are reasonable at the time made. The unaudited pro forma condensed combined financial statements do not purport to present the financial position or results of operations of NTL had the acquisitions occurred on the dates specified, nor are they necessarily indicative of the financial position or results of operations that may be achieved in the future. The unaudited pro forma condensed combined statements of operations do not reflect any adjustments for synergies that NTL expects to realize commencing upon consummation of the acquisitions. No assurances can be made as to the amount of cost savings or revenue enhancements, if any, that may be realized. 3 NTL INCORPORATED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS (UNAUDITED) FOR THE YEAR ENDED DECEMBER 31, 1998 (IN THOUSANDS, EXCEPT PER SHARE DATA) PRO FORMA NTL COMTEL PARTNERS EGT FOR PRIOR DIAMOND (HISTORICAL) (HISTORICAL) (HISTORICAL) (HISTORICAL) ADJUSTMENTS ACQUISITIONS (HISTORICAL) ------------ ------------ ------------ ------------ ----------- ------------ ------------ REVENUES.................... $ 747,015 $ 97,222 $105,348 $17,110 $ (789)C $ 965,906 $ 147,078 COSTS AND EXPENSES Operating expenses.......... 372,134 62,393 33,965 7,893 -- 476,385 47,088 Selling, general and administrative expenses.... 299,494 32,285 48,448 -- -- 380,227 61,573 Franchise fees.............. 25,036 -- -- -- -- 25,036 -- Corporate expenses.......... 17,048 -- 3,977 -- -- 21,025 -- Non-recurring charges.......

The credit facility bore interest at LIBOR plus 3% per annum increasing by 0.25% per annum each month beginning three months after the first drawdown to a maximum of 4% per annum. In November 1998, the credit facility was repaid using most of the proceeds from the issuance of our 11 1/2% notes and the 12 3/8% notes.
