Item 7. Financial Statements, Pro Forma Financial Information and Exhibits.

  The attached presents American Tower Corporation's (the Company) unaudited
pro forma condensed consolidated balance sheet as of September 30, 2000 and
unaudited proforma condensed consolidated statements of operations for the
nine months ended September 30, 2000 and the year ended December 31, 1999 and
notes thereto.

  The term pro forma transactions, as used in the Company's pro forma
condensed consolidated financial statements and notes thereto, is defined as
certain of the Company's major acquisitions and financings and includes the
following: the OmniAmerica merger, the Telecom merger, the UNIsite merger, the
ICG transaction, the AirTouch transaction, the AT&T transaction, the Company's
public offering of common stock and private placement of common stock in
February 1999 (February 1999 offerings), the Company's notes placement in
October 1999 (October 1999 notes placement), the Company's notes placement in
February 2000 (February 2000 notes placement) and the Company's public
offering of common stock in June 2000 (June 2000 offering). The pro forma
financial statements do not reflect all of the Company's consummated or
pending acquisitions. The adjustments assume that all pro forma transactions
were consummated on January 1, 1999, in the case of the unaudited pro forma
condensed consolidated statements of operations. The adjustments assume that
the then pending pro forma transactions were consummated as of September 30,
2000 in the case of the unaudited pro forma condensed consolidated balance
sheet. These pro forma financial statements should be read in conjunction with
the 1999 Annual Report on Form 10-K, quarterly report on Form 10-Q dated
November 13, 2000 and reports on Form 8-K dated September 17, 1999 and March
30, 2000. Although the AirTouch transaction and the AT&T transaction do not
involve the acquisition of a business, we have provided pro forma information
related to these transactions as we believe such information is material.

  The pro forma condensed consolidated financial statements may not reflect
the Company's financial condition or our results of operations had these
events actually occurred on the dates specified. They may also not reflect the
Company's future financial condition or results of operations.

See Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements. 3 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS We have prepared the unaudited pro forma condensed consolidated balance sheet as of September 30, 2000 to give effect, as of such date, to the remaining portion of the AirTouch and AT&T transactions, the only pro forma transactions not completed by that date. We will account for the remaining portions of the AirTouch and AT&T transactions under the purchase method of accounting. (a) The following table sets forth the pro forma balance sheet adjustments as of September 30, 2000 (in thousands):

- -------- (1) Upon completion of our evaluation of the purchase price allocations, we expect that the average life of the assets should approximate 15 years. (2) As of September 30, 2000 the Company had closed on 1,778 of the 2,100 towers included in the original AirTouch lease agreement, paid $677.3 million in cash, and issued warrants to purchase 3.0 million shares of Class A common stock at a price of $22.00 per share. The warrants vest based on the percentage of towers closed to total towers in the lease agreement (2,100). It is estimated that the Company will pay total consideration of approximately $70.8 million to close on an additional 172 towers through January 2001. The Company does not expect to close on approximately 150 towers included in the original agreement. (3) As of September 30, 2000 the Company has closed on 1,918 of the 1,942 towers included in the AT&T purchase agreement and paid $258.7 million in cash. It is estimated that the Company will pay approximately $1.3 million to close on any remaining towers. 4 AMERICAN TOWER CORPORATION UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS Nine Months Ended September 30, 2000 (in thousands, except per share data)

See Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements. 5 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The unaudited pro forma condensed consolidated statement of operations for the nine months ended September 30, 2000 gives effect to the pro forma transactions as if each of them had occurred on January 1, 2000. We have not adjusted the pro forma condensed consolidated statement of operations to reflect exchanges of our convertible notes for shares of our Class A common stock in May 2000. (a) To record the results of operations for the pro forma transactions. We have adjusted the results of operations to record a decrease in net interest expense of $4.6 million for the nine months ended September 30, 2000 as a result of the decrease in debt after giving effect to the proceeds of the February 2000 notes placement and the June 2000 offering. Debt issuance costs are being amortized on a straight-line basis over the term of the obligation. Amortization of issuance costs are included within interest expense. We have also adjusted the results of operations to record depreciation and amortization expense of $16.7 million for the nine months ended September 30, 2000 based on estimated allocations of purchase prices. With respect to unallocated purchase price, we have determined pro forma depreciation and amortization expense based on an expected average life of 15 years. The table below sets forth the detail for the pro forma transactions for the nine months ended September 30, 2000 (in thousands). The UNIsite operations for the 12 day period ended January 12, 2000 (acquisition closed January 13, 2000) have been excluded from the nine month period ended September 30, 2000 pro forma statement of operations due to immateriality.

(c) Includes adjustment for the 12.5 million shares of Class A common stock issued pursuant to the June 2000 offering. (d) Includes additional revenues recognized on a straight-line basis in accordance with terms stipulated in the AirTouch lease agreement (assumes the leasing of 1,950 towers). Approximately $3.5 million of annual third- party lease revenues existing as of the date the agreement was signed has not been included. (e) Includes additional revenues recognized on a straight-line basis in accordance with terms stipulated in the AT&T and AT&T Wireless Services lease agreements (assumes the acquisition of 1,942 towers). Approximately $7.6 million of annual third-party lease revenues existing as of the date the agreements were signed has not been included. (f) The towers involved in each of these acquisitions were operated as part of the wireless service divisions of AirTouch and AT&T. Accordingly, separate financial records were not maintained and financial statements were never prepared for the operation of these towers. In addition to land leases that we have assumed, we have estimated certain operating expenses we would expect to incur based on our own experience with comparable towers and with AirTouch and AT&T towers acquired to date. Such estimates include expenses related to utilities, repairs and maintenance, insurance and real estate taxes. These operating expenses are based on management's best estimate and, as such, the actual expenses may be different than the estimate presented. 6 AMERICAN TOWER CORPORATION UNAUDITED PRO FORMA CONDENSED CONSOLIDATED STATEMENT OF OPERATIONS Year Ended December 31, 1999 (in thousands, except per share data)

See Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements. 7 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 1999 gives effect to the pro forma transactions as if each of them had occurred on January 1, 1999. We have not adjusted the pro forma condensed consolidated statement of operations to reflect exchanges of our convertible notes for shares of our Class A common stock in May 2000. (a) To record the results of operations for the pro forma transactions. We have adjusted the results of operations to: (1) reverse historical interest expense associated with the companies included in the pro forma transactions; and (2) record an increase in net interest expense of $35.7 million for the year ended December 31, 1999 as a result of the increased debt after giving effect to the proceeds of the February 1999 offerings, the October 1999 notes placement, the February 2000 notes placement and the June 2000 offering. Debt discount is being amortized using the effective interest method. Debt issuance costs are being amortized on a straight-line basis over the term of the obligation. Amortization of debt discount and issuance costs are included within interest expense. We have also adjusted the results of operations to reverse historical depreciation and amortization expense of $18.8 million for the year ended December 31, 1999 and recorded depreciation and amortization expense of $105.6 million for the year ended December 31, 1999 based on estimated allocations of purchase prices. With respect to unallocated purchase price, we have determined pro forma depreciation and amortization expense based on an expected average life of 15 years. We have not carried forward certain corporate general and administrative expenses of the prior owners into the pro forma condensed consolidated financial statements. These costs represent duplicative facilities and compensation to owners and/or executives we did not retain, including charges related to the accelerated vesting of stock options and bonuses that were directly attributable to the purchase transactions. Because we already maintain our own separate corporate headquarters, which provides services substantially similar to those represented by these costs, we do not expect them to recur following the acquisition. After giving effect to an estimated $2.8 million of incremental costs, we believe that we have existing management capacity sufficient to provide the services without incurring additional incremental costs. 8 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The following table sets forth the detail for the pro forma transactions for the year ended December 31, 1999 (in thousands).
