Global Crossing Reports GCUK’s First Quarter Results

FOR IMMEDIATE RELEASE: MONDAY, JUNE 14, 2010

London — Global Crossing Limited (NASDAQ: GLBC), a leading global IP solutions provider, today announced first quarter results for its subsidiary, Global Crossing (UK) Telecommunications Limited (GCUK).

Highlights

For the first quarter of 2010, GCUK generated revenue of 78 million pounds and Operating Income Before Depreciation and Amortization (OIBDA) of 20 million pounds. (OIBDA is a non-GAAP measure defined and reconciled below.) The company also reported cash use from operations of 8 million pounds before interest payments of 1 million pounds.

“Our investments in new products and services, and the expansion of our enterprise sales force are progressing as planned,” said John Legere, chief executive officer of Global Crossing. “These actions will enable us to diversify and profitably grow GCUK’s revenue over the coming quarters of 2010.”

First Quarter Results

GCUK generated revenue of 78 million pounds, flat sequentially and a year-over-year decrease of 1 percent. The year-over-year decline was primarily due to a decrease in wholesale voice revenue.

Gross profit was 29 million pounds for the quarter, a 1 million pound increase sequentially and year over year. The sequential and year-over-year increase in gross profit was principally due to an improvement in revenue mix with lower equipment and professional services costs, partially offset by an increase in access costs.

GCUK’s OIBDA for the first quarter was 20 million pounds, compared with 16 million pounds in the fourth quarter of 2009 and 17 million pounds in the first quarter of 2009. The sequential and year-over-year increases were driven by 6 million pounds of property tax and insurance recoveries in the quarter, partially offset by an increase in accrued incentive compensation, salaries and commissions and higher restructuring provisions for real estate.

GCUK recorded a net loss of 5 million pounds for the first quarter, compared with a net loss of 2 million pounds in both the fourth quarter of 2009 and the first quarter of 2009. The sequential and year-over-year increases in net loss were primarily due to an unfavorable foreign exchange impact on net U.S. dollar-denominated debt.

Cash and Liquidity

As of March 31, 2010, GCUK had cash and cash equivalents of 33 million pounds, compared with 37 million pounds at the end of December 31, 2009, and 33 million pounds at the end of March 31, 2009.

GCUK’s cash and cash equivalents decreased 4 million pounds in the first quarter. Net cash used in operating activities during the first quarter totaled 9 million pounds, including cash use from operating working capital of 27 million pounds and interest payments of 1 million pounds. During the quarter, GCUK recorded purchases of property, plant and equipment of 5 million pounds, and principal payments on finance leases and other debt of 3 million pounds. In addition, GCUK borrowed 13 million pounds from Global Crossing Europe Limited, a subsidiary of Global Crossing Limited, for general corporate purposes.

In accordance with the indenture governing the senior secured notes, on May 14, 2010, the company repurchased approximately 0.2 million pounds of its senior secured notes, including aggregate principal amount and accrued and unpaid interest.

International Financial Reporting Standards

GCUK’s results reported here include unaudited consolidated financial results for the three months ended March 31, 2010, December 31, 2009 and March 31, 2009; the unaudited consolidated balance sheet as of March 31, 2010; and the audited consolidated balance sheet as of December 31, 2009, all in accordance with IFRS and in pounds sterling, as published by the International Accounting Standards Board (IASB). GCUK’s results for the first quarters of 2010 and 2009 and the fourth quarter of 2009 were included in Global Crossing’s consolidated results previously reported on April 28, 2010, in accordance with U.S. GAAP and in U.S. dollars.

Non-GAAP Financial Measures

Consistent with the U.S. Securities and Exchange Commission’s (SEC’s) Regulation G, the attached tables include a definition of OIBDA, as well as a reconciliation of such measure to the most directly comparable financial measure calculated in accordance with IFRS.

SUPPLEMENTAL INFORMATION PROVIDED PURSUANT TO THE INDENTURE GOVERNING THE GCUK SENIOR SECURED NOTES

GCUK is required to provide the holders of its Senior Secured Notes due 2014 with quarterly information pursuant to Section 4.17(a)(2) of the indenture governing such notes. For quarters prior to the first quarter of 2010, GCUK satisfied this requirement by providing the note holders with a quarterly report separate and apart from its quarterly earnings press releases. Starting with the first quarter of 2010, GCUK will satisfy this requirement by providing the note holders with its quarterly earnings press releases. This schedule of supplemental information is being included with the earnings release to ensure the information being provided complies with Section 4.17(a)(2) of the indenture.

Liquidity and Capital Resources

In the long term, GCUK expects its operating results and cash flows to improve as a result of growth of its revenues, including the economies of scale expected to result from such growth, and from ongoing cost management initiatives, including initiatives to optimize the access network and effectively lower unit prices. Thus, in the long term, GCUK expects to generate positive cash flow from operating activities in an amount sufficient to fund all investing and financing requirements, subject to the need to refinance its existing major debt instruments as described below. However, its ability to improve cash flows is subject to the risks and uncertainties, such as the variability of quarterly liquidity, discussed below.

In the short term, GCUK expects cash provided by operating activities to exceed purchases of property and equipment. In addition, its short term liquidity and more specifically its quarterly cash flows are subject to considerable variability as a result of the timing of interest payments as well as the factors noted below.

•

Working capital variability significantly impacts its cash flows and can cause its intra-quarter cash balances to drop to levels significantly lower than those levels prevailing at the end of a quarter.

•

Adverse general economic conditions could cause customer buying patterns with GCUK to change as a result of their cash conservation efforts, which could have an adverse impact on its cash flows. Such adverse conditions could also adversely impact its working capital to the extent suppliers seek more timely payment from GCUK or customers pay GCUK on a less timely basis.

•

Within 120 days after each calendar year, GCUK must offer to purchase a portion of the Senior Secured Notes at 100% of their principal amount with 50% of the Operating Cash Flow (as defined in the Indenture) for that year. In respect of 2009, it offered to purchase £11.8 million of the Notes, excluding accrued interest and purchased £0.2 million of the Notes, plus accrued interest through the purchase date.

•

GCUK’s liquidity may also be adversely affected if it is found liable in respect of contingent legal, tax and other liabilities. The amount and timing of the resolution of these contingencies remain uncertain.

Financing activities

On March 30, 2010, GCUK entered into a £0.9 million finance lease facility with Huawei Technologies (UK) Co Ltd which was fully drawn down at that time. The lease is subject to an applicable rate of interest of 8% per annum, with payments made over a period of 18 months from April 30, 2010.

On March 31, 2010, GCUK borrowed $20.0 million from Global Crossing Europe Limited (“GCE”), a subsidiary of Global Crossing Limited. The loan matures on September 15, 2013 and accrues interest at 12% per annum, payable semi-annually on March 15 and September 15 of each year.

Schedule 6

Global Crossing (UK) Telecommunications Limited and Subsidiaries

Reconciliation of OIBDA to Net Loss

Results below are in pounds sterling in thousands

Pursuant to the SEC’s Regulation G, the following table provides a reconciliation of OIBDA, which is considered a non-GAAP (Generally Accepted Accounting Principles) financial measure, to net loss under IFRS.

OIBDA is defined as operating profit before depreciation and amortization and foreign exchange gains (losses) on operating working capital movements, based upon our consolidated statements of operations. OIBDA differs from operating profit, in that it excludes depreciation and amortization. Such excluded expenses primarily reflect the non-cash impacts of historical capital investments, as opposed to the cash impacts of capital expenditures made in recent periods. In addition, OIBDA does not give effect to cash used for debt service requirements and thus does not reflect available funds for reinvestment, distributions or other discretionary uses.

Management uses OIBDA as an important part of our internal reporting and planning processes and as a key measure to evaluate profitability and operating performance, make comparisons between periods, and to make resource allocation decisions. Management believes that the investment community uses similar performance measures to compare performance of competitors in our industry.

There are material limitations to using non-GAAP financial measures. Our calculation of OIBDA may differ from similarly titled measures used by other companies, and may not be comparable to those other measures. Additionally, OIBDA does not include certain significant items such as depreciation and amortization, finance revenue, finance charges, foreign exchange gains (losses) income taxes and other non-operating profit or loss items. OIBDA should be considered in addition to, and not as a substitute for, other measures of financial performance reported in accordance with GAAP.

Management believes that OIBDA is useful to our investors as it is a relevant indicator of operating performance, especially in a capital-intensive industry such as telecommunications. OIBDA provides investors with an indication of the underlying performance of our everyday business operations. It excludes the effect of items associated with our capitalization and tax structures, such as interest income, interest expense and income taxes, and of other items not associated with our everyday operations.
