PART II. OTHER INFORMATION

XO Communications, Inc.
Notes to Interim Consolidated Financial Statements
(Unaudited)

1.    Basis of Presentation

      The consolidated financial statements include XO Communications, Inc., formerly known as NEXTLINK Communications, Inc., a Delaware corporation, and its majority-owned subsidiaries (together with its predecessors, referred to, collectively, as the Company). The Company, through predecessor entities, was formed in September 1994 and, through its subsidiaries, provides competitive local, long distance and enhanced telecommunications and data transmission and related services in selected markets in the United States. The Company is majority controlled by Craig O. McCaw through shares of Class A and Class B common stock held by Eagle River Investments, LLC, an entity controlled by Mr. McCaw, and other shares of the Company’s Class A and Class B common stock owned by Mr. McCaw or over which he has voting control.

      The Company’s financial statements include 100% of the assets, liabilities and results of operations of subsidiaries of which the Company has control. The Company’s investments in unconsolidated companies in which it has a less than majority interest but exercises significant influence are accounted for using the equity method and are included in other assets. Investments in entities in which the Company has no significant influence are accounted for using the cost method and are also included in other assets. All significant intercompany accounts and transactions have been eliminated.

      The interim financial statements are unaudited and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 1999, as filed with the Securities and Exchange Commission on March 30, 2000.

      The financial information included herein reflects all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the results for interim periods. The results of operations for the three-month and nine-month periods ended September 30, 2000 are not necessarily indicative of the results to be expected for the full year.

      On June 15, 2000, the Company effected a two-for-one stock split in the form of a 100% stock dividend to holders of its common stock as of the June 1, 2000 record date. Share and per share data has been adjusted to reflect the stock dividend.

2.    Significant Transactions

      On June 16, 2000, the Company merged with Concentric Network Corporation (Concentric), a provider of high-speed digital subscriber line, or DSL, web hosting, e-commerce, and other Internet and data transmission services. In the merger (the Concentric merger), the Company issued shares of the Company’s Class A common stock and assumed liabilities of Concentric. The aggregate value of the common stock and the assumed liabilities was approximately $3.6 billion.

      The Concentric merger was acccounted for using the purchase method of accounting. The consideration and purchase price allocation were as follows (in thousands):

Stock issued	$	2,542,356
Liabilities, warrants and options assumed		1,050,476
Consideration	$	3,592,832
In-process technology		36,166
Fair value of intangible assets acquired		246,234
Fair value of tangible assets		384,861
Goodwill		2,925,571
	$	3,592,832

      As a result of the Concentric merger, each issued and outstanding share of Concentric common stock was converted into 1.2868 shares of the Company’s Class A common stock. Approximately 68 million shares of the Company’s Class A common stock were issued to Concentric common stockholders. The Company assumed all obligations under Concentric’s $150.0 million of 12 3/4% senior notes due 2007 outstanding at the time of the merger. The 12 3/4% senior notes rank pari passu with the Company’s other outstanding senior notes. Additionally, outstanding shares of Concentric’s preferred stock were converted into 195,079 shares of the Company’s 13 1/2% Series E senior redeemable exchangeable preferred stock due 2010, and 53,296 shares of the Company’s 7% Series F convertible redeemable preferred stock due 2010. The 7% Series F preferred stock is convertible into an aggregate of 1.7 million shares of the Company’s Class A common stock.

      In connection with the Concentric merger, outstanding warrants to purchase Concentric common stock were converted into warrants to acquire shares of the Company’s Class A common stock based on the 1.2868 exchange ratio applicable to the Concentric common stock. Also, the Company assumed certain Concentric employee stock option and other benefit plans. As a result of the Concentric merger, holders of Concentric options and warrants outstanding at the time of the merger received the right to acquire approximately 17.6 million shares of the Company’s Class A common stock in the aggregate.

      The results of operations of Concentric have been included in the accompanying condensed consolidated statements of operations of the Company from June 16, 2000, the date of acquisition. The accompanying condensed consolidated financial statements also reflect the allocation of the purchase price, which is subject to adjustment. The goodwill of $2.9 billion is being amortized on a straight-line basis over five years. Other acquired intangible assets which include developed technology, customer lists, work force and trade names are being amortized on a straight-line basis over four years.

      Of the $3.6 billion purchase price, $36.2 million was allocated to in-process technology. The Company retained professional appraisal consultants to assist the Company with the assessment and allocation of a portion of the purchase price to the in-process technology. These allocations represent the estimated fair value based on risk-adjusted future cash flows related to the incomplete projects. At the date of the Concentric merger, the development of these projects had not yet reached technological feasibility and the technology had no alternative future uses. As such, the entire $36.2 million of in-process technology acquired was expensed as of the acquisition date.

      The pro forma operating results of the Company and Concentric for the nine months ended September 30, 2000 and 1999 have been prepared assuming the merger occurred on January 1, 1999 (dollars in thousands).

	Nine Months Ended
	September 30, 2000			September 30, 1999
Pro forma revenue	$	577,134		$	285,477
Pro forma net loss applicable to common shares	$	(1,060,018	)	$	(967,333	)
Pro forma loss per share	$	(3.04	)	$	(3.09	)

      The pro forma results do not purport to represent what the Company’s results of operations would have actually been had the merger occurred on the date indicated and are not indicative of future results.

      On June 16, 2000, the Company acquired Craig O. McCaw’s 50% interest in LHP, L.L.C. which owns 100% of INTERNEXT, L.L.C., in exchange for approximately 6.8 million shares of the Company’s Class A common stock and the assumption of $9.9 million in liabilities. As a result of the transaction, the Company now owns 100% of INTERNEXT L.L.C., which owns exclusive rights to multiple “dark” fibers and empty conduits in the 16,000 mile, 50 city North American inter-city broadband network that is currently being constructed. The transaction was accounted for as a reorganization of entities under common control and, accordingly, was recorded by the Company at Mr. McCaw’s historical cost.

3.    Long Term Debt Financing

      In February 2000, the Company and certain of its subsidiaries, as guarantors, entered into a $1.0 billion secured credit facility (the facility) with various lenders. The facility is comprised of a $387.5 million senior secured multi-draw term loan A, a $225.0 million senior secured term loan B, and a $387.5 million revolving credit facility. At closing, the Company borrowed $150.0 million of the term loan A and the entire $225.0 million of the term loan B. As of September 30, 2000, no additional borrowings have been drawn under the facility.

      The security for the facility consists of all of the assets purchased with the proceeds of the facility, the stock of certain of the Company’s direct subsidiaries, all assets of the Company and, to the extent of $125.0 million of guaranteed debt, all assets of certain of the Company’s subsidiaries.

      Amounts drawn under the facility will bear interest, at the option of the Company, at an alternate base rate or reserve-adjusted LIBOR plus, in each case, applicable margins. Initially, the applicable margins for the term loan A and the revolving credit facility are 175 basis points over the alternate base rate and 275 basis points over LIBOR. After June 30, 2003, the applicable margins for the term loan A and the revolving credit facility range from 62 1/2 to 150 basis points over the alternate base rate and from 162 1/2 to 250 basis points over LIBOR, based on the ratio of the Company’s consolidated total debt to annualized consolidated EBITDA, as defined in the agreements relating to the credit facility. The applicable margin for the term loan B is fixed at 250 basis points over the alternate base rate and 350 basis points over LIBOR. Specific rates are determined by actual borrowings under each facility. Interest on the term loans and the revolving credit facility is payable on the earlier of the last day of each interest period, or each successive date three months after the first day of such interest period.

      The term loan A and the revolving credit facility mature on December 31, 2006, and the term loan B matures on June 30, 2007. In each case, the maturity dates are subject to acceleration to October 31, 2005 if the Company has not refinanced its 12 1/2% Senior Notes due 2006 by April 15, 2005. The term loans A and B and the revolving credit facility provide for automatic and permanent quarterly reductions of the amount available for borrowing under those facilities, beginning on March 31, 2004. The term loan B contains nominal amortization provisions beginning March 31, 2004 until maturity.

      The facility contains certain covenants, which, among other things, limit additional indebtedness, certain investments and other transactions, and dividend payments.

4.    Redeemable Preferred Stock

      In July 2000, the Company sold 268,750 shares of Series G cumulative convertible participating preferred stock and 131,250 shares of Series H convertible participating preferred stock to several investment funds controlled by Forstmann Little & Co. Each share of Series G and Series H stock has a liquidation preference of $1,000 per share plus accrued and unpaid dividends. The sale generated gross proceeds of $400.0 million. The Series G and Series H stock are convertible into shares of the Company’s Class A common stock at a conversion rate of $31.625 per share, and provide for a 3.75% annual dividend that is payable quarterly. The holders may convert the preferred stock into Class A common stock at any time after January 20, 2001.

      Shares of issued and outstanding preferred stock, redeemable in amounts equal to their respective aggregate liquidation preferences, are summarized in the table below (dollars in thousands):

	Shares Issued & Outstanding as of				Aggregate Liquidation Preference as of

PART I.       FINANCIAL INFORMATION

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operation

OVERVIEW

Our Business and Assets

      Since 1996, we have provided high-quality bundled local and long distance, as well as dedicated voice telecommunications services to the rapidly growing business market. We have expanded our services, through our acquisition of Concentric Network Corporation on June 16, 2000, to offer a complete, single source communications solution to our customers by combining our data and voice services. Our data services include the following:

• Internet Access. Our Internet access offerings, enabled by significant peering arrangements, include dedicated access facilities targeted at businesses that desire single or multipoint high-speed, dedicated connections to the Internet, at speeds ranging from 56 Kbps to 45 Mbps, and digital subscriber line, or DSL, services that include a wide range of dedicated access speeds.

• Virtual Private Network. Our virtual private network, or VPN, services enable customers to deploy tailored, Internet Protocol-based mission-critical business applications for secure internal enterprise, business-to-business and business-to-customer data communications among geographically dispersed locations, while also affording high-speed access to the Internet.

• Hosting Services. We offer a range of applications hosting services, including hosting and Web site traffic management solutions for Internet-centric businesses, and Web hosting, e-commerce, and streamed media services designed for small-to-medium sized businesses. Together, these Web hosting services manage a customer’s Web-based infrastructure and operational needs allowing customers to focus on their Web-based content. In addition, we provide server management tools and services to completely manage customers’ servers for them.

• Ethernet Services. We launched a suite of Ethernet services, including Gigabit Ethernet, or GigE, in selected markets in November, and we expect to launch those services throughout most of our 53 markets in the United States by mid-next year. Our Gigabit Ethernet solution is designed to connect customers’ local area networks, or LANs, within a metropolitan area, using extensive metro fiber assets currently spanning more than 4,300 route miles. These assets, combined with our suite of Ethernet services, are expected to yield private networking data speeds ranging from 10 to 100 Mbps and 1 Gbps connections which are designed to both simplify the customers’ network connections and significantly reduce customers’ costs.

      To complement these service offerings, in September 2000, we introduced revolutionary flat rate service packages throughout all of our 53 domestic markets. These convenient packages combine local, long distance, Internet Access and web hosting (including e-mail and domain registration) services designed specifically for small and medium-sized businesses.

      We believe that increasing usage of both telephone service and newer data application and information services will continue to increase demand for telecommunications capacity, and for new telecommunications services and applications. To serve our customers’ broad and expanding telecommunications needs, we have assembled a unique collection of high-bandwidth, local and inter-city network assets, both in North America and Europe. We intend to integrate these assets with advanced communications technologies and services to become one of the leading global providers of comprehensive communications services.

      To accomplish this, we have:

• built 33 metropolitan broadband fiber optic networks in 19 states, generally focused on the central business districts of the cities we serve, and we are continuing to build additional networks;

• become the nation’s largest holder of fixed wireless spectrum by acquiring Federal Communications Commission, or FCC, licenses covering 95% of the population of the 30 largest U.S. cities, which we will use to extend the reach of our networks to additional customers;

• acquired rights to use unlit fiber optic strands, known as dark fiber, and an empty conduit that will allow us to deploy additional fiber optic strands in a North American inter-city broadband network now being completed that will traverse over 16,000 miles and to connect more than 50 cities in the United States and Canada, including most of the major metropolitan markets that our current and planned local networks serve;

• announced plans to expand our existing European operations pursuant to a non-binding agreement in principle providing for the purchase of:

• five metropolitan networks in London, Frankfurt, Brussels, Amsterdam and Paris,

• rights to multiple dark fibers on a 3,700 mile inter-city network that will connect 21 cities through five European countries and

• transatlantic fiber optic capacity connecting North America and Europe, initially at 2.5 Gbps and expanding to 10 Gbps by the end of 2002; and

• acquired, through a Canadian joint venture, six broadband fixed wireless spectrum licenses covering Toronto, Montreal, Vancouver, Ottawa, Edmonton, Calgary and surrounding areas, which the joint venture plans to use, in conjunction with other network assets, to offer data and voice services comparable to those offered in the U.S.

      Our local and inter-city networks employ fiber optic technology, which uses light waves to transmit signals over cables consisting of many glass fiber strands. Fiber optic strands have enough capacity to carry tens of thousands times more traffic than traditionally-configured copper wire. In our newer markets, we install as many as 400 advanced fiber strands in each network, with built-in capacity for future growth. Our North American inter-city network will consist of 24 of the most advanced fiber strands and an empty conduit through which we can deploy numerous additional fiber strands. Recent advances in transmission technology, notably dense wave division multiplexing, or DWDM, have substantially increased the effective capacity of advanced fiber strands.

      Our goal is to own our networks or control them through the acquisition of dark fiber, which we believe will enable us to deliver higher quality and new services at a lower cost, thereby increasing our operating margins. Ownership of networks or rights to dark fiber gives us the flexibility to deploy optical transmission equipment designed to support a variety of communications technologies, enabling us to maximize our network’s capacity and performance. This flexibility will allow us to offer our customers a wide range of technology options to meet their changing needs and introduce new technologies as they become available.

      We have recently begun the first phase of an expansive migration to packet-based switching technology, which is expected to deliver the full range of traditional and enhanced local and long distance services and to increase our ability to efficiently handle an increasing amount of ISP traffic. We plan to deploy an Internet Protocol (IP)-based next-generation telecommunications switching platform, including soft-switch technology, throughout our North American fiber optic network over the next 18 months. Soft-switch technology is expected to allow us to realize cost savings both in reduced equipment cost and reduced physical co-location space needs. Additionally, switches using soft-switch technology are expected to be quickly scaleable and have capabilities to launch new and enhanced services.

      Another key component of our strategy is to own or control the physical connection for the short distance between our customers’ facilities and our networks. To make this connection, today we frequently lease the existing copper telephone wires from the dominant local telephone company. To reduce our reliance on these leased connections, we intend to increase the number of customers connected directly to our networks. In some cases, we will make this direct connection by constructing a new fiber optic extension from our network to the customer’s premises. In other cases, using our fixed wireless spectrum, we will deploy a high-bandwidth wireless connection between an antenna on the roof of the customer’s premises and an antenna attached to our fiber rings. These wireless connections offer high-quality broadband capacity and, in many cases, cost less than fiber to install. We have deployed wireless direct connections to our networks in 17 markets, and plan to have them deployed in a total of 25 markets by the end of 2000.

      We are also deploying DSL technology to meet the high bandwidth needs of those customers whose connection to our network remains over copper wire. DSL technology increases the effective capacity of existing copper

telephone wires. We are installing DSL equipment to provide these services ourselves, and we also resell other providers’ DSL services.

2000 Transactions and Developments

      Name Change

      In September 2000, in connection with the launch of our flat rate service packages, we announced that the XO Communications name would replace the NEXTLINK and Concentric brands in the marketplace, which is reflective of our core business strengths and signifies our transformation into a full-service, integrated broadband communications provider offering services that are both simple to use and understand. We began trading under the new ticker symbol (NASDAQ:XOXO) on Tuesday, September 26, 2000.

      Acquisition of Concentric Network

      On June 16, 2000, we consummated the acquisition of Concentric. In the merger and after giving effect to the June 15, 2000 two-for-one split, approximately 68 million shares of our Class A common stock were issued to Concentric common stockholders. In connection with the Concentric merger, we assumed Concentric’s outstanding warrants and employee stock option and other benefit plans and, to the extent such warrants and plans provided for the issuance or purchase of Concentric common stock, they now provide for the issuance or purchase of shares of our Class A common stock.

      In the merger, each issued and outstanding share of preferred stock of Concentric was converted into a share of a corresponding series of our preferred stock, with substantially identical terms as the corresponding series of preferred stock of Concentric (giving effect to amendments approved by the holders of those shares). Additionally, as a result of the merger, we have assumed the payment obligations and all other covenants required to be performed or observed by Concentric with respect to its 12 3/4% senior notes due 2007.

      Acquisition of Interest in North American Inter-City Network

      On June 16, 2000, Craig O. McCaw contributed to us his interest in the joint venture with us that owns exclusive interests in multiple “dark” fibers and empty conduits in a North American inter-city telecommunications network currently under construction. We now own all of these exclusive interests. In exchange for his interest, Mr. McCaw received approximately 6.8 million shares of our Class A common stock and we assumed $9.9 million in liabilities. In connection with this acquisition, we granted Mr. McCaw certain registration rights with respect to the Class A common stock issued to Mr. McCaw in the exchange. Mr. McCaw is a member of our board of directors and controls Eagle River Investments, L.L.C., our largest stockholder.

RESULTS OF OPERATIONS

Comparison of Financial Results

      Revenue grew 198.8% to $224.3 million during the third quarter of 2000 from $75.1 million in the same period in 1999. Year to date revenue of $470.8 million represented a 155.4% increase from the $184.3 million in revenue for the comparable period in 1999. In June 2000, we consummated a merger with Concentric which contributed to the increase in revenue over the comparable periods in 1999. Revenue reported consisted of the following components (in thousands):

	Three Months							Nine months
	Ended September 30,							Ended September 30,
	2000		1999		% Change			2000		1999		% Change
Data services	$	117,940	$	13,838		752.3	%	$	194,114	$	32,094		504.8	%
Voice services		103,943		58,365		78.1	%		273,888		149,030		83.8	%
Other services		2,371		2,856		(17.0	%)		2,751		3,178		(13.4	%)
Total revenue	$	224,254	$	75,059		198.8	%	$	470,753	$	184,302		155.4	%

      Data services includes revenue from Internet access, network access, and web hosting. Internet access services include services marketed to enterprise customers, such as dedicated access facilities and DSL services, and residential and small business dial-up access services which offers access at speeds up to 56 kbps across the United States and Canada. Network access services include primarily dedicated and VPN services, which enable customers to deploy tailored, IP-based business applications for internal enterprise, business-to-business and business-to-customer data communications on the private network while also affording high-speed access to the Internet. Applications hosting services include sophisticated high-end hosting and Web site traffic management solutions for Internet-centric businesses, in addition to web hosting, e-commerce and streamed media services designed for small-to-medium sized businesses. At September 30, 2000, we had 23,140 DSL lines in service. With respect to dedicated web hosting services, we had 2,582 managed servers residing in our 8 data centers. Hosted websites over shared servers totaled 212,327.

      Voice services revenue, consisting of bundled local and long distance, prepaid call processing, and other voice services including shared tenant services, interactive voice response, or IVR, and stand-alone long distance services, grew 78.1% to $103.9 million for the third quarter of 2000 from $58.4 million in the same period of 1999. For the nine months ended September 30, 2000, voice services revenue grew 83.8% to $273.9 million from $149.0 million

for the comparable period in 1999. This revenue growth can be attributed primarily to an increase in customer access lines installed, which was driven by growth in our existing markets as well as by new markets launched. At September 30, 2000, access lines in service totaled 737,433 compared to 349,154 as of September 30, 1999, an increase of 111.2%. Access line installations grew 69.3% to 110,271 and 76.8% to 309,398 for the three and nine months ended September 30, 2000 compared to 65,133 and 174,972 for the same periods of 1999.

      The table below provides expenses by classification and as a percentage of revenue (dollars in thousands):

				Three Months Ended
		September 30, 2000					September 30, 1999
		Amount		% of Revenue			Amount		% of Revenue
Costs and expenses:
	Operating	$	144,107		64.3	%	$	59,328		79.0	%
	Sales, general and administrative		169,082		75.4	%		71,322		95.0	%
	Stock-based compensation		13,396		6.0	%		2,535		3.4	%

	Amortization		175,634		78.3	%		3,166		4.2	%

				Nine Months Ended
		September 30, 2000					September 30, 1999
		Amount		% of Revenue			Amount		% of Revenue
Costs and expenses:
	Operating	$	317,015		67.3	%	$	156,395		84.9	%
	Sales, general and administrative		374,452		79.5	%		182,755		99.2	%
	Stock-based compensation		39,609		8.4	%		4,711		2.6	%
	Depreciation		139,984		29.7	%		67,429		36.6	%
	Amortization		216,788		46.1	%		11,177		6.1	%

      Operating expenses consist of costs directly related to providing facilities-based network and enhanced communications services,and also include salaries, benefits and related costs of operations and engineering personnel. Operating expenses increased 142.9% in the third quarter of 2000 to $144.1 million, an increase of $84.8 million over the same period in 1999. For the nine months ended September 30, 2000, operating expenses increased 102.7% to $317.0 million from $156.4 million over the same period in 1999. The increase was attributable to increased network costs related to provisioning higher volumes of local, long distance and enhanced communications services, an increase in employees, and an increase in other related costs primarily to expand our switched local and long distance service businesses in existing and planned markets as well as the inclusion of Concentric operating expenses from June 16, 2000, the date the Concentric merger was completed.We expect operating expenses to continue to increase in future periods in connection with our growth and expansion plans, but to decrease as a percentage of revenue.

      Selling, general and administrative, or SG&A, expenses include salaries, benefits and related personnel costs for non-operating and non-engineering personnel, facilities expenses, sales and marketing, information systems costs, consulting and legal fees. SG&A increased 137.1% to $169.1 million in the third quarter of 2000 from $71.3 million in the third quarter of 1999. For the nine months ended September 30, 2000, SG&A increased 104.9% to $374.5 million from $182.8 million in the same period of 1999. Consistent with the cost drivers of our operating expenses,

the increase was primarily due to an increase in the number of our employees, and other costs associated with the expansion of our local and long distance service businesses in our existing and planned markets, as well as the inclusion of Concentric SG&A expenses from the merger date. We expect SG&A to continue to increase in future periods in connection with growth and expansion plans.

      Stock-based compensation expense was recorded in connection with compensatory stock options granted to employees and also includes the cost associated with restricted stock granted to certain key Concentric officers and employees in connection with the Concentric merger. Compensation expense is recognized over the vesting periods of compensatory stock options based on the excess of the fair value of the stock options at the date of grant over the exercise price. Stock-based compensation expense increased $10.9 million in the third quarter of 2000 to $13.4 million relative to $2.5 million in the third quarter of 1999. For the nine months ended September 30, 2000, stock-based compensation expense increased $34.9 million to $39.6 million from $4.7 million in the same period of 1999. The increase was due to the issuance of compensatory stock options to senior executives during the latter half of 1999 and in the first half of 2000 and the issuance and accrual for issuance of restricted stock to Concentric employees in association with the Concentric merger.

      Depreciation expense increased 132.2% to $58.7 million from $25.3 million in the third quarter of 1999. For the nine months ended September 30, 2000, depreciation expense increased 107.6% to $140.0 million from $67.4 million in the same period of 1999. The increase was primarily due to placement in service of additional telecommunications network assets, including switches, fiber optic cable, network electronics and related equipment and the impact of Concentric’s depreciation expense included from the merger date. We expect depreciation expense to continue to increase as we expand our networks and install additional equipment associated with data and voice technologies.

      Amortization expense increased $172.5 million to $175.6 million in the third quarter of 2000 and $205.6 million to $216.8 million for the nine months ended September 30, 2000 due to amortization of additional goodwill and intangible assets arising from the Concentric merger.

      Interest expense increased 37.1% to $108.9 million from $79.4 million in the third quarter of 1999. For the nine months ended September 30, 2000, interest expense increased 70.7% to $324.6 million from $190.2 million in the same period of 1999. The increase was primarily due to an increase in our average outstanding indebtedness over the respective periods, resulting, to a large extent, from the issuance of senior notes in June 1999 and November 1999, a $375.0 million draw on our senior secured credit facility in the first quarter of 2000, and the inclusion of interest expense associated with Concentric’s senior notes, from the merger date. For more information, see “Liquidity and Capital Resources.”

      Interest income increased 105.7% to $50.2 million from $24.4 million in the third quarter of 1999. For the nine months ended September 30, 2000, interest income increased 129.0% to $141.3 million from $61.7 million in the same period of 1999. The increase in interest income corresponds with the increase in our cash and investment balances.

      We reported a net loss of $394.2 million for the third quarter of 2000 compared to a net loss of $141.6 million for the same quarter of 1999. The increased loss is a result of increases in costs associated with the expansion of our business through internal growth and acquisition of new businesses. For the nine months ended September 30, 2000, we reported a net loss of $609.7 million compared to a net loss of $366.6 million for the nine months ended September 30, 1999. The net loss for the nine month period ended September 30, 2000, takes into account our $226.5 million gain on sale of investment.

Other Operating Data

      The table below summarizes EBITDA, both in amount and as a percentage of revenue. EBITDA is our operating loss adjusted for stock based compensation, depreciation, amortization and in-process technology write-offs for the periods noted (dollars in thousands):

				Three Months Ended												Nine months Ended
	September 30, 2000						September 30, 1999						September 30, 2000						September 30, 1999
	Amount			% of Revenue			Amount			% or Revenue			Amount			% of Revenue			Amount			% or Revenue
EBITDA	$	(88,935	)		(39.7	%)	$	(55,591	)		(74.1	%)	$	(220,714	)		(46.9	%)	$	(154,848	)		(84.0	%)

      EBITDA is not a generally accepted accounting principle measure but rather a measure employed by management to view operating results adjusted for major non-cash items. EBITDA has been consistently improving as a percentage of revenue due to revenue growth and the decrease in operating and SG&A as a percentage of revenue as indicated above. In absolute dollars, our EBITDA loss has increased due to business expansion costs as discussed above.

LIQUIDITY AND CAPITAL RESOURCES

      Our business is capital-intensive and, as such, has required and will continue to require substantial capital investment. We build high capacity networks with broad market coverage, a strategy that initially increases our level of capital expenditures and operating losses and requires us to make a substantial portion of our capital investments before we realize any revenue from them. These capital expenditures, together with the associated early operating

expenses, will continue to result in negative cash flow unless and until we are able to establish an adequate customer base. We believe, however, that over the long term this strategy will enhance our financial performance by increasing the capacity of, and traffic flow over, our networks.

Capital Uses

      During the first nine months of 2000, cash used in operating activities was $238.6 million, compared to $231.5 million used in the same period in the prior year. The increase in cash used was primarily due to the timing of expenditures and customer receipts.

      During the first nine months of 2000, cash used in investing activities was $1,264.7 million, compared to $887.7 million used in the same period in the prior year. Our investment in property and equipment increased from $396.0 million for the first nine months of 1999 to $853.7 million for the same period of 2000. This increase was offset by a decrease in investments in fixed wireless licenses year-over-year from $488.5 million invested in the first nine months of 1999 to $37.3 million for the nine months ended September 30, 2000. The increase in cash used in investing activities for the first nine months of 2000 also was offset partially due to the receipt of $245.1 million from the sale of an equity investment and $46.9 million of net cash acquired in the Concentric merger.

      We expect that our business will continue to require substantial amounts of cash expenditures to fund operations and capital expenditures in 2000 and beyond relating to our existing and planned network development and operations. These funds are expected to relate to:

• the purchase and installation of switches, routers, servers and other data-related equipment and related electronics in existing networks, for expansion of existing networks and in networks to be constructed or acquired in new markets;

• the purchase and installation of fiber optic cable and electronics to expand existing networks and develop new networks, including the connection of new buildings;

• the development of our comprehensive information technology platform;

• the purchase and installation of equipment associated with the deployment of fixed wireless services using our fixed wireless spectrum;

• funding of the commitments to build our North American inter-city network, our European inter-city and metro networks, and our transatlantic capacity, and related expenses we expect to incur in building these networks;

• the purchase and installation of equipment associated with deployment of DSL and other data services;

• the funding of the Wispra Networks Canadian joint venture, of which we are a member; and

• the funding of operating losses and working capital.

      Our strategic plan also calls for expansion into additional market areas. This expansion will require significant additional capital for:

• potential acquisitions of businesses or assets;

• design, development and construction of new networks; and

• the funding of operating losses and working capital during the start-up phase of each market.

Acquired Debt and Redeemable Preferred Stock

      In connection with the Concentric merger, we assumed the payment obligations and all other covenants required to be performed or observed by Concentric with respect to the $150 million of Concentric’s 12 3/4% senior notes due 2007 outstanding at the time of the merger. The 12 3/4% senior notes rank pari passu with our other outstanding senior notes. With the consent of the holders of Concentric’s 12 3/4% senior notes due 2007, and in consideration for the payment of a consent fee of approximately $3.0 million, we conformed certain covenants contained in the indenture relating to Concentric’s senior notes to corresponding covenants in our 10 1/2% senior notes due 2009. We may redeem the 12 3/4% senior notes, in whole or in part, at any time on or after December 15, 2002, at redemption rates (expressed as a percentage of the principal amount) commencing with 106.375% on December 15, 2002, and declining to 100.0% on December 15, 2005, plus accrued and unpaid interest to the date of redemption.

      As a result of the Concentric merger, the 195,079 shares of Concentric’s 13 1/2% senior redeemable exchangeable preferred stock due 2010 outstanding at the time of the merger were converted into an equal number of shares of our 13 1/2% Series E senior redeemable exchangeable preferred stock, which has substantially identical terms as the Concentric 13 1/2% preferred stock. With the consent of the holders of Concentric’s 13 1/2% preferred stock, and in consideration for the payment of a consent fee of approximately $3.8 million, we conformed certain covenants contained in the certificate of designations relating to Concentric’s preferred stock to corresponding covenants in our 10 1/2% senior notes due 2009. Each share has a liquidation preference of $1,000 per share. The Company may redeem the Series E shares, in whole or in part, at any time on or after June 1, 2003, at redemption rates (expressed as a percentage of the liquidation preference) commencing with 106.75% on June 1, 2003 and declining to 100% on June 1, 2008, plus accumulated and unpaid dividends to the date of redemption. The Company is required to redeem the Series E shares at their liquidation preference, plus accumulated and unpaid dividends on June 1, 2010. On any scheduled dividend payment date, the Company may, at its option, exchange in whole, but not in part, the then outstanding Series E shares for 13 1/2% senior subordinated debentures due 2010 with a principal amount equal to the aggregate liquidation preference of the exchanged Series E shares. Dividends on the 13 1/2% preferred stock accrue at a rate of 13 1/2% per annum of the liquidation preference thereof and are payable quarterly in arrears. Dividends are payable in cash, except that on each dividend payment date occurring on or prior to June 1, 2003, dividends may be paid, at our option, by the issuance of additional shares of Series E preferred stock having an aggregate liquidation preference equal to the amount of such dividends.

      In addition, as a result of the Concentric merger, 53,296 shares of Concentric 7% convertible redeemable preferred stock outstanding at the time of the merger were converted into an equal number of shares of our 7% Series F convertible redeemable preferred stock, which has substantially identical terms to Concentric’s 7% preferred stock. Each share of 7% preferred stock has a liquidation preference of $1,000 per share. The Company may redeem the Series F shares, in whole or in part, at any time on or after June 1, 2003 at redemption rates commencing with 105.125% declining to 100% on June 1, 2010. The Company is required to redeem the Series F shares at their liquidation preference, plus accumulated and unpaid dividends, on September 1, 2010. Dividends on the 7% preferred stock accrue at the rate of 7% per annum of the liquidation preference thereof and are payable quarterly in arrears. Dividends are payable in cash, except that on each dividend payment date dividends may be paid, at our option, by the issuance of additional shares of Series F preferred stock having an aggregate liquidation preference equal to the amount of such dividends. The holder of shares of Series F preferred stock has the right, at its option, to convert at any time any shares of Series F preferred stock into shares of our Class A common stock at the conversion price of $31.0258.

Capital Resources

      As of September 30, 2000, we had unrestricted cash and marketable securities of $2,710.2 million. During the first nine months of 2000, cash provided by financing activities was $1,621.6 million, compared to $1,297.7 million in the same period in the prior year. We received $1,248.9 million, net of financing fees, from the issuance of preferred stock to Forstmann Little & Co. and $375.0 million from the draws on credit facility in the first nine months of 2000. During the same period in 1999, we received $1,000.0 million from a public offering of senior notes and $310.5 million from a public offering of our Class A common stock.

      Secured Credit Facility. In February 2000, we and certain of our subsidiaries, as guarantors, entered into a $1.0 billion secured credit facility with various lenders. The security for the facility consists of all of the assets purchased with the proceeds thereof, the stock of certain of our subsidiaries, all assets of the Company and, to the extent of $125.0 million of guaranteed debt, all assets of certain of our subsidiaries. A portion of the facility is available to provide working capital and for other general corporate purposes with the remainder available to provide financing for the construction, acquisition or improvement of telecommunication assets. The facility consists of a $387.5 million multi-draw term loan A, a $225.0 million term loan B, and a $387.5 million revolving facility. In addition, the facility may be increased by up to an additional $1.0 billion under certain circumstances. At closing, we borrowed $150.0 million of the term loan A and the entire $225.0 million of the term loan B. As of September 30, 2000, no additional borrowings had been made under the facility.

      The revolving credit facility and the term loan A mature on December 31, 2006, and the term loan B matures on June 30, 2007. The maturity date for each of the facilities may be accelerated to October 31, 2005 unless we have refinanced our $350 million 12 1/2% Senior Notes by April 15, 2005. Amounts drawn under the revolving credit facility and the term loans bear interest, at our option, at the alternate base rate or reserve-adjusted London Interbank Offered Rate (LIBOR) plus, in each case, applicable margins.

      Forstmann Little Investments. In December 1999, several investment funds controlled by Forstmann Little & Co. agreed to invest $850.0 million in the Company, to be used to expand our networks and services, introduce new technologies and fund our business plan. The investment was completed in January 2000. Forstmann Little & Co. invested an additional $400.0 million in the Company in July 2000 increasing their total investment to $1.25 billion. In the transactions, the investors acquired shares of four series of convertible preferred stock that together are convertible into Class A common stock at a conversion price of $31.625 per share and provide for a 3.75% dividend payable quarterly. The holders of these preferred shares may convert the preferred stock into Class A common stock at any time after January 20, 2001. We may redeem the Series C and Series D preferred stock at any time after the later of January 20, 2005 or the date we have redeemed our 12 1/2% Senior Notes due 2006 in full, and may redeem the Series G and Series H preferred stock at any time after the later of July 6, 2005 or the date when we have redeemed our 12 1/2% Senior Notes due 2006 in full. The holders of the Series C and Series D preferred shares will also have the option of requiring redemption of the preferred stock during the 180-day period commencing January 20, 2010. The holders of the Series G and Series H preferred shares will also have the option of requiring redemption of the preferred stock during the 180-day period commencing on July 6, 2010.

Liquidity Assessment

      We believe that the amounts available under the secured credit facility, cash and marketable securities on hand at September 30, 2000, and revenues from operations will provide sufficient funds for us to expand our business as planned and to fund operating losses into the latter half of 2001. However, the amount of future funding requirements will depend on a number of factors, including the success of our business, the dates at which we further expand our network, the types of services we offer, staffing levels, acquisitions and customer growth, as well as other factors that are not within our control including competitive conditions, government regulatory developments and capital costs. In the event our plan or assumptions change or prove to be inaccurate, or available borrowings under the secured credit facility, cash and investments on hand and cash generated from operations prove to be insufficient to fund our growth in the manner and at the rate currently anticipated, we may be required to delay or abandon some or all of our development and expansion plans or we may be required to seek additional sources of financing earlier than currently anticipated. In the event we are required to seek additional financing, there can be no assurance that such financing will be available on acceptable terms or at all.

INFORMATION REGARDING FORWARD LOOKING STATEMENTS

      Some statements and information contained in this report are not historical facts, but are “forward-looking statements”, as such term is defined in the Private Securities Litigation Reform Act of 1995. These forward-looking statements can be identified by the use of forward-looking terminology, such as “believes,” “expects,” “plans,” “may,” “will,” “would,” “could,” “should,” or “anticipates” or the negative of these words or other variations of these words or other comparable words, or by discussions of strategy that involve risks and uncertainties. Such forward-looking statements include, but are not limited to, statements regarding:

• market development, the number of markets we expect to serve, and the expected number of addressable business lines in such markets;

• network development, including those with respect to IP and ATM network and facilities development and deployment, switches using soft-switch technology, broadband fixed wireless technology, testing and installation, high speed technologies such as DSL, and matters relevant to our national network; and

• liquidity and financial resources, including anticipated capital expenditures, funding of capital expenditures and anticipated levels of indebtedness.

      All such forward-looking statements are qualified by the inherent risks and uncertainties surrounding expectations generally, and also may materially differ from our actual experience involving any one or more of these matters and subject areas. The operation and results of our business also may be subject to the effect of other risks and uncertainties in addition to the relevant qualifying factors identified in this report and in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 1999, filed with the Securities and Exchange Commission on March 30, 2000, including, but not limited to:

• general economic conditions in the geographic areas that we are targeting for communications services;

• the ability to achieve and maintain market penetration and revenue levels sufficient to provide financial viability to our business;

• access to sufficient debt or equity capital to meet our operating and financing needs;

• the quality and price of similar or comparable communications services offered or to be offered by our competitors; and

• future telecommunications-related legislation or regulatory actions.

NEW ACCOUNTING STANDARDS

      In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No. 133 “Accounting for Derivative Instruments and Hedging Activities,” which establishes accounting and reporting standards for derivative instruments and hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the balance sheet and measure those instruments at fair value. The standard was initially proposed to be effective for all fiscal quarters of all fiscal years beginning after June 15, 1999, however the FASB issued SFAS 137 “Accounting for Derivative Instruments and Hedging Activities – Deferral of the Effective Date of FASB Statement No. 133”, and the effective date of this SFAS has been deferred until issuance by the FASB. Management believes that the adoption of SFAS 133 will not materially impact the Company’s results of operations or financial position.

      In December 1999, the Securities and Exchange Commission (“the SEC”) issued Staff Accounting Bulletin No. 101, “Revenue Recognition in Financial Statements” (“SAB No. 101”) that provides guidance for applying generally accepted accounting principles to revenue recognition, presentation, and disclosure in financial statements. Subsequently, the SEC has amended the implementation date so that the Company is required to adopt the provisions of SAB No. 101 in the fourth fiscal quarter of 2000. We believe that the bulletin will not materially impact the Company’s results of operations or financial position.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

      We currently have instruments sensitive to market risks relating to exposure to changing interest rates. As disclosed in the consolidated financial statements, we had $4,366.0 million in fixed rate debt and $2,071.4 million in fixed rate redeemable preferred stock as of September 30, 2000. We do not have significant cash flow exposure to changing interest rates on our long term debt and redeemable preferred stock because the interest rates are fixed. However, the estimated fair values of the fixed-rate debt and redeemable preferred stock are subject to market risk.

      We also maintain an investment portfolio consisting of U.S. government and other securities with an average maturity of less than one year. These securities are classified as “available for sale”. If interest rates were to increase or decrease immediately, it could have a material impact on the fair value of these financial instruments. However, changes in interest rates would not likely have a material impact on interest earned on our investment portfolio. We do not currently hedge these interest rate exposures.

      There have been no material changes in market risk since December 31, 1999.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

      The Company, as successor to Concentric in the Concentric merger, is a defendant in a lawsuit filed in New Jersey state court on November 1, 1999. The complaint seeks statutory damages, treble damages, and injunctive relief under the Telephone Consumer Protection Act of 1991 and alleges that, in or about March and June 1999, 9Net Avenue, Inc. (9Net Avenue) transmitted unsolicited facsimiles advertising its services. Although Concentric purchased only the assets of 9Net Avenue and did not assume any liabilities related to 9Net Avenue’s activities prior to the October 1999 asset purchase, plaintiff contends that Concentric succeeded to any liability 9Net Avenue incurred in connection with the alleged faxes. The suit has been brought as a purported class action on behalf of all recipients of the allegedly unsolicited faxes. In October 2000, the trial judge in the case ruled that the requirements for a class action were not met. In October 2000, the plaintiffs representing the purported class filed an appeal of the class certification decision, which the New Jersey Court of Appeals has agreed to consider.

Item 2.    Changes in Securities and Use of Proceeds

      The initial public offering (IPO) of our Class A common stock took place in October 1997 (File No. 333-32001). The net proceeds we received from the offering totaled approximately $226.8 million. As of December 31, 1999, proceeds from the IPO remain available for future network build out and working capital requirements. We have raised additional funding from debt and additional equity offerings in 1998 through 2000. The proceeds from these recent offerings have been applied first in funding the expansion of our network and other working capital requirements.

Item 3.    Defaults Upon Senior Securities

      None.

Item 4.    Submission of Matters to a Vote of Security Holders

      On September 11, 2000, our Board of Directors approved an amendment to our certificate of incorporation to change the name of the company to the XO Communications, Inc. This amendment also was approved by two of our stockholders, Eagle River Investments, L.L.C. and Wendy P. McCaw, by a written consent in lieu of stockholder meeting, dated September 11, 2000, pursuant to Section 228(a) of the Delaware General Corporation Law. As of September 11, 2000, Eagle River and Mrs. McCaw together held shares of our Class A and Class B common stock that represent shares with a majority of the total number of votes attributable to all shares of outstanding capital stock entitled to vote for the amendment. Because we are a corporation organized under the laws of the State of Delaware, our stockholders may take action by written consent without a meeting. The Board has not solicited any proxies or consents from any other stockholders in connection with this action. The amendments became effective on October 25, 2000, 20 days following the date on which we mailed an information statement with respect to the amendment to stockholders of XO, in accordance with rules of the Securities and Exchange Commission.
