PART I. FINANCIAL INFORMATION

ITEM 1. FINANCIAL STATEMENTS

PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Basis of Presentation

    The accompanying unaudited consolidated financial statements of Primus Telecommunications Group, Incorporated (the "Company" or "Primus") have been prepared in accordance with generally accepted accounting principles for interim financial reporting and Securities and Exchange Commission ("SEC") regulations. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all adjustments (of a normal and recurring nature) which are necessary to present fairly the financial position, results of operations, cash flows and comprehensive loss for the interim periods. The results for the three months ended March 31, 2001 are not necessarily indicative of the results that may be expected for the year ending December 31, 2001.

    The financial statements should be read in conjunction with the Company's audited consolidated financial statements included in the Company's most recently filed Form 10-K.

(2) Summary of Significant Accounting Policies

    Principles of Consolidation—The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and all other subsidiaries over which the Company exerts control. The Company owns 51% of the common stock of Matrix Internet, S.A. ("Matrix"), 51% of Cards & Parts Telecom GmbH ("Cards & Parts"), 51% of CS Communications Systems GmbH and CS Network GmbH ("Citrus"), 37% of Bekkoame Internet, Inc. ("Bekko"), and 60% of Direct Internet Private Limited ("DIPL"), all of which the Company has a controlling interest. All material intercompany profits, transactions and balances have been eliminated in consolidation. All other investments in affiliates are carried at cost, as the Company does not have significant influence.

    New Accounting Pronouncements—In June 1998, Statement of Financial Accounting Standards No. 133 ("SFAS 133"), "Accounting for Derivative Instruments and Hedging Activities," was issued. SFAS 133 established standards for the accounting and reporting of derivative instruments and hedging activities and requires that derivative financial instruments, including certain derivative instruments embedded in other contracts, be measured at fair value and recognized as assets or liabilities in the financial statements. The Company adopted SFAS 133 in the three months ended March 31, 2001. The adoption of SFAS 133 did not have a material effect on the consolidated financial position or results of operations of the Company.

(3) Acquisitions

    The Company acquired a 19% interest in Liquor Industry Services Technology (Australia) Pty Ltd ("LIST"), an Australian B2B business, for $0.6 million during the year ended December 31, 2000. In March 2001, the Company received the remaining 81% of LIST for no additional monetary consideration; LIST desired to be a part of a larger organization to sustain its operations.

    The Company has accounted for this acquisition using the purchase method of accounting, and accordingly, the net assets and results of operations of the acquired company have been included in the Company's financial statements since the acquisition date. The purchase price, including direct costs, of the Company's acquisition was allocated to the net assets acquired, including intangible assets and liabilities assumed, based on their respective fair values at the acquisition date. The valuation of the

5

---

Company's acquired assets and liabilities for the acquisition is preliminary, and as a result, the allocation of the acquisition costs among tangible and intangible assets may change.

(4) Marketable Securities

    In connection with a strategic business arrangement with Pilot Network Services ("Pilot"), in January 2000, the Company made a $15.0 million strategic investment in Pilot pursuant to which the Company purchased 919,540 shares, or 6.3%, of Pilot's common stock at a price of $16.3125 per share, and received a warrant to purchase an additional 200,000 shares at $25.00 per share. In March 2001, the Company wrote-off the investment of $15.0 million which is reported in Interest and Other Income (Expense). Based on current market quotes, the Company considered the decline in fair value to be permanent.

(5) Goodwill and Other Intangible Assets

    Goodwill and other intangible assets consist of the following (in thousands):

    Amortization expense for Goodwill and Other Intangible Assets for the three months ended March 31, 2001 was $15.4 million.

(6) Long-Term Obligations

    Long-term obligations consist of the following (in thousands):

    The indentures governing the senior notes and convertible debentures, as well as other credit arrangements, contain certain financial and other covenants which, among other things, will restrict the Company's ability to incur further indebtedness and make certain payments including the payment of dividends.

Hewlett-Packard also agreed to purchase up to $50 million in convertible debt. As of March 31, 2001, Hewlett-Packard funded the entire $50 million under the agreement. The convertible note is due in March 2005. Such debt will bear interest at a rate of 9.25% per annum. The outstanding principal and unpaid accrued interest are convertible into the Company's common stock at a price of $60 per share. As of March 31, 2001, the debt is convertible into 852,604 shares of the Company's common stock.

Until converted, the debt will be secured by equipment purchased from Hewlett-Packard with the proceeds of the investment.

(7) Operating Segment and Related Information

    The Company has three reportable operating segments based on management's organization of the enterprise into geographic areas—North America, Europe and Asia-Pacific. The Company evaluates the performance of its segments and allocates resources to them based upon net revenue and operating income/(loss). The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company offers voice, data, Internet, e-commerce, Web hosting, enhanced application, voice over Internet protocol (VOIP), virtual private network and other value-added services in all three segments. The Company also offers digital subscriber line (DSL) in North America and Asia-Pacific. Net revenue by reportable segment is reported on the basis of where services are provided. The Company has no single customer representing greater than 10% of its revenues. Operations and assets of the North America segment include shared corporate functions and assets, which the Company does not allocate to its other geographic segments for management reporting purposes.

    Summary information with respect to the Company's segments is as follows (in thousands):

(8) Commitments and Contingencies

    In December 1999, the Company agreed to purchase approximately $23.2 million of fiber capacity from Qwest Communications which will provide the Company with an asynchronous transfer mode (ATM) + Internet protocol (IP) based international broadband backbone of nearly 11,000 route miles of fiber optic cable in the United States and overseas as well as private Internet peering at select sites in the United States and overseas. In March 2000, the Company agreed to purchase an additional $20.8 million of fiber capacity. The Company has purchased $25.5 million under the agreements as of March 31, 2001.

    In December 2000, the Company entered into a financing arrangement for the purchase of fiber optic capacity under an IRU Agreement in Australia for 67.6 million Australian Dollars from Optus Networks Pty. Limited. The lease term begins in fiscal year 2001 and is payable over a four-year term with an interest rate of 14.29%.

    On December 9, 1999, Empresa Hondurena de Telecommunicaciones, S.A., based in Honduras, filed suit in Florida State Court in Broward County against TresCom and one of TresCom's wholly-owned subsidiaries, St. Thomas and San Juan Telephone Company, alleging that such entities failed to pay amounts due to plaintiff pursuant to contracts for the exchange of telecommunications traffic during the period from December 1996 through September 1998. The Company acquired TresCom in June 1998 and TresCom is currently the Company's subsidiary. Plaintiff is seeking approximately $14 million in damages, plus legal fees and costs. The Company filed an answer on January 25, 2000 and discovery has commenced. The Company's ultimate legal and financial liability with respect to such legal proceeding cannot be estimated with any certainty at this time, while an adverse result for the full amount sought or some significant percentage thereof could have a material adverse effect on the Company's financial results. The Company intends to defend the case vigorously. Management believes that this suit will not have a material adverse effect on the financial condition, results of operations or cash flows of the Company.

    The Company is subject to certain other claims and legal proceedings that arise in the ordinary course of its business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be decided unfavorably to the Company. Management believes that any aggregate liability that may ultimately result from the resolution of these matters will not have any material adverse effect on the financial condition or results of operations or cash flows of the Company.

(9) Stockholder's Equity

    On January 10, 2001, the Company received from Inktomi Corporation an investment, which is a part of a strategic alliance created between the two companies in June 2000, of $10 million in exchange for 2,862,254 restricted shares of the Company's common stock.

(10) Related Parties

    In January 2001, the Company loaned an officer of the Company the principal amount of $0.8 million in full recourse note. This loan is payable in full five years from the date of agreement (subject to earlier repayments upon the termination of the officer's employment under certain circumstances) and is secured by shares of the Company's common stock. Interest is compounded quarterly at a rate of 6% per annum and payable upon maturity. The portion of this note related to the issuance of stock is reflected as a reduction of stockholder's equity.

(11) Gain on Early Extinguishment of Debt

    In January 2001, the Company exchanged 8,308,258 shares of the Company's common stock for the extinguishment of $129.6 million in principal amount of the 2000 Convertible Debentures and purchased $38.2 million of principal amount of its high yield debt and convertible debentures, prior to maturity, for $11.6 million in cash. This resulted in an extraordinary gain of $106.1 million, or $2.11 per basic and diluted share. There was no tax provision due to the availability of Net Operating Loss Carryforwards.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

    Primus is a global facilities-based Total Service Provider offering bundled voice, data, Internet, DSL, e-commerce, Web hosting, enhanced application, VOIP, virtual private network (VPN) and other value-added services to business and residential retail customers and other carriers located in the United States, Canada, Brazil, the United Kingdom, continental Europe, Australia and Japan. The Company seeks to capitalize on the increasing demand for high-quality international communications services, which is being driven by the globalization of the world's economies, the worldwide trend toward telecommunications deregulation and the growth of global data and Internet traffic. The Company provides services over its network, which consists of (i) 23 carrier-grade switches, including 19 international gateway switches in the United States, Australia, Canada, France, Germany, Japan, Puerto Rico and the United Kingdom and four domestic switches in Australia; (ii) more than 300 points of presence (POPs) and Internet access nodes in additional markets within our principal service regions; (iii) both owned and leased transmission capacity on undersea and land-based fiber optic cable systems; and (iv) an international satellite earth station located in London, together with the capacity the Company leases on an Intelsat satellite. Utilizing this network, along with resale arrangements and foreign carrier agreements, the Company provides service to approximately 2.1 million customers.

    The Company's net revenue is derived from carrying a mix of business, residential and carrier long distance traffic, data and Internet traffic and in the United States, Canada, Brazil, United Kingdom, continental Europe, Australia and Japan, also from the provision of both local and cellular services in selected markets. Long distance net revenue is earned based on the number of minutes billable and is recorded upon completion of a call, adjusted for sales allowance. The Company generally prices its services at a savings compared to the major carriers operating in its principal service regions. The Company expects to generate net revenue from internal growth through sales and marketing efforts focused on customers with significant international long distance usage, including small- and medium-sized businesses, multinational corporations, ethnic residential customers and other telecommunications carriers and resellers.

    Cost of revenue is comprised primarily of costs incurred from other domestic and foreign telecommunications carriers to originate, transport and terminate calls. The majority of the Company's cost of revenue is variable, based upon the number of minutes of use, with transmission and termination costs being the Company's most significant expense. As the Company increases the portion of traffic transmitted over its leased or owned facilities, cost of revenue increasingly will be comprised of fixed costs.

    Although the Company's functional currency is the United States dollar, a significant portion of the Company's net revenue is derived from its sales and operations outside the United States. In the future, the Company expects to continue to derive a significant portion of its net revenue and incur a significant portion of its operating costs from outside of the United States; therefore, changes in foreign currency exchange rates have had and may continue to have a significant, and potentially adverse, effect on the Company's results of operations. The Company historically has not engaged in hedging transactions and does not currently contemplate engaging in hedging transactions to mitigate foreign exchange risks.

Results of operations for the three months ended March 31, 2001 as compared to the three months ended March 31, 2000.

    Net revenue decreased $8.0 million or 3% to $280.0 million for the three months ended March 31, 2001, from $288.0 million for the three months ended March 31, 2000.

North America: The Company's North American net revenue decreased $2.2 million or 2% from $127.6 million for the three months ended March 31, 2000 to $125.4 million for the three months ended March 31, 2001. The decrease is primarily attributed to $7 million in additional sales allowance to write-off bad debts from "dot-com" customers associated with 1492 Technologies, an acquired Web design/consulting business whose operations were discontinued during the three months ended March 31, 2001, and the negative impact of the declining value of the Canadian dollar against the United States dollar. The decrease is partially offset by increased traffic volumes in carrier operations and to a lesser extent increases in business and residential retail operations in the Company's Canadian division. The decrease is also offset by the results of operations of the Company's 2000 acquisitions including Shore.Net (since the March 2000 acquisition) and CTE (since the June 2000 acquisition).

Europe: European net revenue decreased $3.0 million or 4% from $85.4 million for the three months ended March 31, 2000 to $82.4 million for the three months ended March 31, 2001. The European net revenue decrease is primarily attributed to the negative impact of declining foreign currency exchange rates against the United States dollar and decisions made by the Company's carrier group not to carry traffic from other carriers who are in distressed financial circumstances. Additionally, the Company recorded approximately $1 million in additional sales allowance in the three months ended March 31, 2001 to cover several carrier and business customer bad debts from failing companies. The decrease is partially offset by the addition of LCR Telecom (since the February 2000 acquisition), Citrus (since the February 2000 acquisition), A-Tel (since the May 2000 acquisition) and InterNext (since the May 2000 acquisition).

Asia-Pacific: The Company's Asia-Pacific net revenue decreased $2.7 million or 4% from $74.9 million for the three months ended March 31, 2000 to $72.2 million for the three months

12

---

ended March 31, 2001. The net revenue decrease in the Asia-Pacific region was primarily attributable to the negative impact of declining foreign currency exchange rates against the United States dollar and the continuing competitive pricing pressures. The decrease was partially offset by increased traffic volumes from the provision of local access in Australia, the continued growth in the Company's data and Internet sales in Australia, and the operations of the Company's 2000 acquisitions including Bekko (since the March 2000 acquisition) and DIPL (since the March 2000 acquisition).

    Cost of revenue increased $1.0 million from $207.4 million for the three months ended March 31, 2000 to $208.4 million for the three months ended March 31, 2001. As a percentage of net revenue, the cost of revenue increased by 240 basis points from 72.0% to 74.4%. The increase in the cost of revenue is attributable to the increase in traffic volumes and associated net revenue growth which is offset by the additional sales allowance and the addition of expense from acquired operations including LCR, CTE and Bekko.

    Selling, general and administrative expenses increased $5.6 million to $84.9 million, or 30.3% of net revenue, for the three months ended March 31, 2001 from $79.3 million, or 27.5% of net revenue, for the three months ended March 31, 2000. The increase is partially attributable to severance pay and employee termination costs of approximately $1 million in connection with approximately half of an 11% workforce reduction of full-time employees during the three months ended March 31, 2001. The remaining workforce reduction will be concluded in the three months ended June 30, 2001. The increase is also due to the impact of increased advertising, marketing and sales expenses focused on retail revenue growth as well as the impact of the Company's acquisitions of LCR, CTE and Bekko.

    Depreciation and amortization expense increased by $14.3 million to $36.5 million for the three months ended March 31, 2001 from $22.2 million for the three months ended March 31, 2000. The increase is associated with the increased amortization expense related to intangible assets arising from the Company's acquisitions and with increased depreciation expense related to capital expenditures for fiber optic cable, switching, data center and other network equipment being placed into service. The increase is also attributed to approximately $2 million for the write-off of goodwill for the Company's Web design acquisitions and the write-off of software costs in the three months ended March 31, 2001.

    Interest expense increased from $29.9 million for the three months ended March 31, 2000 to $31.2 million for the three months ended March 31, 2001. The increase is primarily attributable to the $300 million 5³/4% Convertible Subordinated Debentures due 2007 ("2000 Convertible Debentures"), the $50 million 9¹/4% Hewlett-Packard convertible debt, and additional capital lease and equipment financing. The increase is partially offset by the interest savings from the principal reduction of the Company's high yield debt and convertible debentures.

    Interest and other income (expense) decreased to negative $11.5 million for the three months ended March 31, 2001 from $7.6 million for the three months ended March 31, 2000. The decrease is associated with the $15.0 million write-off of the Company's investment in Pilot Network Services because it became permanently impaired in March 2001.

Liquidity and Capital Resources

    The Company's liquidity requirements arise from cash used in operating activities, purchases of network equipment including switches, related transmission equipment and international and domestic fiber optic cable transmission capacity, satellite earth stations and satellite transmission capacity, interest and principal payments on outstanding indebtedness, and acquisitions of and strategic investments in businesses. The Company has financed its growth to date through public offerings, private placements of debt, equity securities, bank debt, equipment financing and capital lease financing.

    Net cash used by operating activities was $51.3 million for the three months ended March 31, 2001 as compared to net cash used by operating activities of $35.8 million for the three months ended March 31, 2000. The increase in operating cash used was comprised of an increase in interest expense and an increase in cost of sales expense and sales, general and administrative expenses. Operating cash was also used to reduce accounts payable, accrued interconnection costs and accrued expenses balances, but was partially offset by higher collections of accounts receivable.

    Net cash used by investing activities was $35.8 million for the three months ended March 31, 2001 compared to net cash used by investing activities of $70.3 million for the three months ended March 31, 2000. Net cash used by investing activities during the three months ended March 31, 2001 included $35.6 million of capital expenditures primarily for the expansion of the Company's global network as compared to $42.2 million during the three months ended March 31, 2000.

    Net cash used by financing activities was $5.1 million for the three months ended March 31, 2001 as compared to net cash provided by financing activities of $315.1 million for the three months ended March 31, 2000. During the three months ended March 31, 2001, cash used by financing activities was $11.6 million for the purchase of certain of the Company's debt securities, $3.7 million of payments on capital leases and other long-term obligations, offset by $10.0 million in cash received from Inktomi Corporation in exchange for 2,862,254 shares of the Company's common stock. Cash provided by financing activities for the three months ended March 31, 2000 resulted primarily from $290.0 million of net proceeds from the sale of the February 2000 Debentures, as well as $25.0 million from the Hewlett-Packard investment, partially offset by $1.5 million of payments on capital leases and other long-term obligations.

    The Company believes that its existing cash and available capital lease and equipment financing (subject to the limitations in the Indentures related to the Company's senior notes and convertible debentures) will be sufficient to fund the Company's operating losses, debt service requirements, capital expenditures, acquisitions and other cash needs for its operations through the second quarter of 2002. The Company is continually evaluating the expansion of its service offerings and plans to make further investments in and enhancements to its switches and distribution channels in order to expand its service offerings. In order to fund these additional cash requirements, the Company anticipates that it will be required to raise additional financing from public or private equity or debt sources. However, the Company may also be required to reduce its expansion and capital expenditures in the event it cannot raise additional capital when needed. In that event, the Company may not be able to service its debt or other obligations and could be required to seek relief from such obligations. Additionally, if the Company's plans or assumptions change, including those with respect to the development of the network and the level of the Company's operations and operating cash flow, if its assumptions prove inaccurate, if it consummates additional investments or acquisitions, if it experiences unexpected costs or competitive pressures, or if existing cash and any other borrowings prove to be insufficient, the Company may be required to seek additional capital sooner than expected.

    The Company presently has no binding commitment or binding agreement with respect to any material acquisition, joint venture or strategic investment. However, from time to time, the Company may be party to one or more non-binding letters of intent regarding material acquisitions which, if consummated, may be paid for with cash or through the issuance of a significant number of shares of the Company's common stock. The Company and/or its subsidiaries will evaluate on a continuing basis the most efficient use of the Company's capital, including investment in the Company's network and systems, lines of business, potential acquisitions, and, depending upon market conditions, purchasing, refinancing or otherwise retiring certain of the Company's outstanding debt and/or equity securities in the open market or by other means to the extent permitted by its existing covenant restrictions.

Special Note Regarding Forward Looking Statements

    Statements in this Form 10-Q, including those concerning the Company's expectations of future sales, net revenue, gross profit, net income, network development, traffic development, capital expenditures, selling, general and administrative expenses, service introductions and cash requirements include certain forward-looking statements. As such, actual results may vary materially from such expectations. Factors, which could cause results to differ from expectations, include risks associated with:

    Liquidity Restrictions; Possible Inability to Obtain Necessary Financing. The Company believes that its existing cash and available capital lease and equipment financing (subject to the limitations in the Indentures related to the Company's senior notes) will be sufficient to fund the Company's operating losses, debt service requirements, capital expenditures, acquisitions and other cash needs for its operations through the second quarter of 2002. The Company is continually evaluating the expansion of its service offerings and plans to make further investments in and enhancements to its switches and distribution channels in order to expand its service offerings. In order to fund these additional cash requirements, the Company anticipates that it will be required to raise additional financing from public or private equity or debt sources. However, the Company may also be required to reduce its expansion and capital expenditures in the event it cannot raise additional capital when needed. In that event, the Company may not be able to service its debt or other obligations and could be required to seek protection under the bankruptcy laws of the United States or other similar laws in other countries. Additionally, if the Company's plans or assumptions change, including those with respect to the development of the network and the level of the Company's operations and operating cash flow, if its assumptions prove inaccurate, if it consummates additional investments or acquisitions, if it experiences unexpected costs or competitive pressures, or if existing cash and any other borrowings prove to be insufficient, the Company may be required to seek additional capital sooner than expected.

    Substantial Indebtedness; Liquidity. The Company currently has substantial indebtedness and anticipates that it and its subsidiaries will incur additional indebtedness in the future. The level of the Company's indebtedness (i) could make it more difficult for it to make payments of interest on its outstanding debt; (ii) could limit the ability of the Company to obtain any necessary financing in the future for working capital, capital expenditures, debt service requirements or other purposes; (iii) requires that a substantial portion of the Company's cash flow from operations, if any, be dedicated to the payment of principal and interest on its indebtedness and other obligations and, accordingly, will not be available for use in its business; (iv) could limit its flexibility in planning for, or reacting to, changes in its business; (v) results in the Company being more highly leveraged than some of its competitors, which may place it at a competitive disadvantage; and (vi) will make it more vulnerable in the event of a downturn in its business.

    Limited Operating History; Entry into Developing Markets. The Company was founded in February 1994, began generating revenue in March 1995. The Company intends to enter additional markets or businesses, including establishing an Internet business, where the Company has limited or no operating experience. Accordingly, the Company cannot provide assurance that its future operations will generate operating or net income, and the Company's prospects must be considered in light of the risks, expenses, problems and delays inherent in establishing a new business in a rapidly changing industry.

    Limited Operating History; Entry into Internet and data business. The Company has recently begun targeting businesses and residential customers for Internet and data services through its subsidiary iPRIMUS.com and other recently acquired ISPs. The Company has been expanding and intends to continue to expand its offering of data and Internet services worldwide. The Company anticipates offering a full-range of Internet protocol-based data and voice communications over the global broadband ATM+IP network which the Company has deployed. The Company has limited

15

---

experience in the Internet and Web hosting business and cannot provide assurance that it will successfully establish or expand the business. Currently, the Company provides Internet services to business and residential customers in the United States, Australia, Canada, Japan, Brazil, Germany, France and Spain, and offers Internet transmission services in the Indian Ocean/Southeast Asia regions through its satellite earth station in London.

    The market for Internet connectivity and related services is extremely competitive. The Company's primary competitors include other ISPs that have a significant national or international presence. Many of these carriers have substantially greater resources, capital and operational experience than the Company does. The Company also expects it will experience increased competition from traditional telecommunications carriers that expand into the market for Internet services. In addition, the Company will require substantial additional capital to make investments in its Internet operations, and it may not be able to obtain that capital on favorable terms or at all. The amount of such capital expenditures may exceed the amount of capital expenditures spent on the voice portion of its business going forward.

    Further, even if the Company is able to establish and expand its Internet business, the Company will face numerous risks that may adversely affect the operations of its Internet business. These risks include:

•

competition in the market for Internet services;



•

the Company's limited operating history as an ISP;



•

the Company's reliance on third parties to provide maintenance and support services for the Company's ATM+IP network;



•

the Company's reliance on third-party proprietary technology to provide certain services to the Company's customers, including, among others, software applications, Web hosting services and VOIP services;



•

the Company's ability to recruit and retain qualified technical, engineering and other personnel in a highly competitive market;



•

the Company's ability to adapt and react to rapid changes in technology related to the Internet business;



•

uncertainty relating to the continuation of the adoption of the Internet as a medium of commerce and communications;



•

vulnerability to unauthorized access, computer viruses and other disruptive problems due to the accidental or intentional actions of others;



•

adverse regulatory developments;



•

the potential liability for information disseminated over the Company's network; and



•

the Company's need to manage the growth of its Internet business, including the need to enter into agreements with other providers of infrastructure capacity and equipment and to acquire other ISPs and Internet-related businesses on acceptable terms.

    Finally, the Company expects to incur operating losses and negative cash flow from its Internet and data business as the Company expands, builds out and upgrades this part of the business. Any such losses and negative cash flow are expected to partially offset the expected positive cash flow generated by the voice business and effectively reduce the overall cash flow of the Company as a whole.

    Managing Rapid Growth. The Company's strategy of rapid growth has placed, and is expected to continue to place, a significant strain on the Company. In order to manage its growth effectively, the

16

---

Company must continue to implement and improve its operational and financial systems and controls, purchase and utilize additional transmission facilities, and expand, train and manage its employees, all within a rapidly-changing regulatory environment. Inaccuracies in the Company's forecast of traffic could result in insufficient or excessive transmission facilities and disproportionate fixed expenses.

    Historical and Future Operating Losses; Negative EBITDA; Net Losses. Since inception, the Company had cumulative negative cash flow from operating activities and cumulative negative EBITDA. In addition, the Company incurred net losses since inception and has an accumulated deficit of approximately $385 million as of March 31, 2001. The Company expects to continue to incur additional operating losses and negative cash flow as it expands its operations and continues to build-out and upgrade its network. There can be no assurance that the Company's revenue will grow or be sustained in future periods or that it will be able to achieve or sustain profitability or positive cash flow from operations in any future period.

    Acquisition and Strategic Investment Risks. Acquisitions, a key element in the Company's growth strategy, involve operational risks, including the possibility that an acquisition does not ultimately provide the benefits originally anticipated by management, while the Company continues to incur operating expenses to provide the services formerly provided by the acquired company, and financial risks including the incurrence of indebtedness by the Company in order to affect the acquisition and the consequent need to service that indebtedness.

    Integration of Acquired Businesses. There can be no assurance that the Company will be successful in identifying attractive acquisition candidates, completing and financing additional acquisitions on favorable terms, or integrating the acquired business or assets into its own. There may be difficulty in integrating the service offerings, distribution channels and networks gained through acquisitions with the Company's own. Successful integration of operations and technologies requires the dedication of management and other personnel which may distract their attention from the day-to-day business, the development or acquisition of new technologies, and the pursuit of other business acquisition opportunities.

    Intense Competition. The long distance telecommunications industry is intensely competitive and is significantly influenced by the marketing and pricing decisions of the larger industry participants. Competition in all of the Company's markets is likely to increase and, as deregulatory influences are experienced in markets outside the United States, competition in non-United States markets is likely to become similar to the intense competition in the United States. Many of the Company's competitors are significantly larger and have substantially greater financial, technical and marketing resources and larger networks than the Company, a broader portfolio of service offerings, greater control over transmission lines, stronger name recognition and customer loyalty, as well as long-standing relationships with the Company's target customers. In addition, many of the Company's competitors enjoy economies of scale that result in a lower cost structure for transmission and related costs which could cause significant pricing pressures within the industry.

    Dependence on Transmission Facilities-Based Carriers. The Company's ability to maintain and expand its business is dependent upon whether the Company continues to maintain favorable relationships with the transmission facilities-based carriers to carry the Company's traffic.

    International Operations. In many international markets, the existing carrier will control access to the local networks, enjoy better brand recognition and brand and customer loyalty, and have significant operational economies, including a larger backbone network and correspondent agreements. Moreover, the existing carrier may take many months to allow competitors, including the Company, to interconnect to its switches within its territory. There can be no assurance that the Company will be able to obtain the permits and operating licenses required for it to operate, obtain access to local transmission facilities or to market services in international markets. In addition, operating in international markets generally involves additional risks, including: unexpected changes in regulatory

17

---

requirements, tariffs, customs, duties and other trade barriers; difficulties in staffing and managing foreign operations; problems in collecting accounts receivable; political risks; fluctuations in currency exchange rates; foreign exchange controls which restrict repatriation of funds; technology export and import restrictions; seasonal reductions in business activity.

    Dependence on Effective Information Systems. The Company's management information systems must grow as the Company's business expands and are expected to change as new technological developments occur. The financial systems in Europe must also be made compliant with the conversion to the Euro currency. There can be no assurance that the Company will not encounter delays or cost-overruns or suffer adverse consequences in implementing new systems when required.

    Industry Changes. The international telecommunications industry is changing rapidly due to deregulation, privatization, technological improvements, expansion of infrastructure and the globalization of the world's economies. In order to compete effectively, the Company must adjust its contemplated plan of development to meet changing market conditions. The telecommunications industry is marked by the introduction of new product and service offerings and technological improvements. The Company's profitability will depend on its ability to anticipate, assess and adapt to rapid technological changes and its ability to offer, on a timely and cost-effective basis, services that meet evolving industry standards.

    Network Development; Migration of Traffic. The long-term success of the Company is dependent upon its ability to design, implement, operate, manage and maintain the network. The Company could experience delays or cost overruns in the implementation of the network, or its ability to migrate traffic onto its network, which could have a material adverse effect on the Company.

    Dependence on Key Personnel. The loss of the services of K. Paul Singh, the Company's Chairman and Chief Executive Officer, or the services of its other key personnel, or the inability of the Company to attract and retain additional key management, technical and sales personnel (for which competition is intense in the telecommunications industry), could have a material adverse effect upon the Company.

    Government Regulation. The Company's operations are subject to constantly changing regulation. There can be no assurance that future regulatory changes will not have a material adverse effect on the Company, or that regulators or third parties will not raise material issues with regard to the Company's compliance or non-compliance with applicable regulations, any of which could have a material adverse effect upon the company.

    Natural Disasters. Many of the geographic areas where the Company conducts its business may be affected by natural disasters, including hurricanes and tropical storms. Hurricanes, tropical storms and other natural disasters could have material adverse effect on the business by damaging the network facilities or curtailing telephone traffic as a result of the effects of such events, such as destruction of homes and businesses.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

    The Company's primary market risk exposures relate to changes in foreign currency exchange rates and to changes in interest rates.

    Foreign currency—Although the Company's functional currency is the United States dollar, a significant portion of the Company's net revenue is derived from its sales and operations outside the United States. In the future, the Company expects to continue to derive a significant portion of its net revenue and incur a significant portion of its operating costs outside the United States, and changes in exchange rates have had and may continue to have a significant, and potentially adverse effect on the Company's results of operations. For example, the Company estimates that the total adverse impact of foreign currency exchange rate changes from the three months ended March 31, 2000 reduced the reported revenue for the three months ended March 31, 2001 by approximately $21 million. Due to the large percentage of the Company's revenues derived outside of the United States, continuing strengthening of the United States dollar would continue to have an adverse impact on the company's results of operations. The operations of affiliates and subsidiaries in foreign countries have been funded with investments and other advances. Due to the long-term nature of such investments and advances, the Company accounts for any adjustments resulting from translation as a charge or credit to "accumulated other comprehensive loss" within the stockholders' equity section of the consolidated balance sheet. The Company historically has not engaged in hedging transactions to mitigate foreign exchange risk.

    Interest rates—We are currently not exposed to material future earnings or cash flow exposures from changes in interest rates on long-term debt obligations because a substantial majority of our long-term debt obligations are at fixed interest rates. However, we are exposed to interest rate risk as additional financing may be required due to the large operating losses and capital expenditures associated with establishing and expanding our networks and facilities. The interest rates that we will be able to obtain on additional financing, if any, will depend on market conditions at that time, and may differ from the rates we have secured on our current debt. We do not currently anticipate entering into interest rate swaps and/or similar instruments. The estimated fair value of the Company's 2000 Convertible Debentures, 1999, 1998 and 1997 Senior Notes (carrying value of $941 million), based on quoted market prices, at March 31, 2001 was $263 million.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

    On December 9, 1999, Empresa Hondurena de Telecommunicaciones, S.A., based in Honduras, filed suit in Florida State Court in Broward County against TresCom and one of TresCom's wholly-owned subsidiaries, St. Thomas and San Juan Telephone Company, alleging that such entities failed to pay amounts due to plaintiff pursuant to contracts for the exchange of telecommunications traffic during the period from December 1996 through September 1998. We acquired TresCom in June 1998 and TresCom is currently our subsidiary. Plaintiff is seeking approximately $14 million in damages, plus legal fees and costs. We filed an answer on January 25, 2000 and discovery has commenced. Our ultimate legal and financial liability with respect to such legal proceeding cannot be estimated with any certainty at this time, while an adverse result for the full amount sought or some significant percentage thereof could have a material adverse effect on our financial results. We intend to defend the case vigorously. Management believes that this suit will not have a material adverse effect on our financial condition, results of operations or cash flows.

    We are subject to certain other claims and legal proceedings that arise in the ordinary course of its business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be decided unfavorably to us. Management believes that any aggregate liability that may ultimately result from the resolution of these matters will not have any material adverse effect on our financial condition or results of operations or cash flows.

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

    In January 2001, the Company received from Inktomi Corporation an investment, which is a part of a strategic alliance created between the two companies in June 2000, of $10 million in exchange for 2,862,254 restricted shares of the Company's common stock.

    In January 2001, the Company exchanged 8,308,258 shares of the Company's common stock for the extinguishment of $129.6 million in principal amount of the 2000 Convertible Debentures and purchased $38.2 million of principal amount of its high yield debt and convertible debentures.
