LONDON, April 29 /PRNewswire/ --

Global Crossing (Nasdaq: GLBC), a leading global IP solutions provider, today announced fourth quarter and full year 2007 financial results for its subsidiary, Global Crossing (UK) Telecommunications Limited (GCUK).

Highlights

GCUK generated 76 million pounds in revenue for the fourth quarter, with adjusted gross margin at 70 percent of revenue and adjusted IFRS EBITDA of 22 million pounds. (Adjusted gross margin and adjusted IFRS EBITDA are non-GAAP metrics that are defined and reconciled below.) Cash provided by operations for the fourth quarter was 16 million pounds before payment of interest.

GCUK continued to add new customers and additional services to existing customer relationships. During the fourth quarter, the company announced a new contract with HM Revenue and Customs (HMRC) under which HMRC will employ Global Crossing's hosted IP telephony service for the operation of all its telephony service across the UK, supporting 85,000 users. HMRC is using the recently launched Global Crossing Unified Communications offering, which provides fully managed hosted IP telephony, collaboration and messaging solutions over a single, converged IP network. In addition, GCUK announced an extension to its Internet Protocol Virtual Private Network (IP VPN) for Superdrug. Following successful implementation of an IP VPN for 700 Superdrug stores, the company expanded the service to an additional 200 retail outlets.

"GCUK exited 2007 as a larger, stronger business than it was in 2006. The combination of Fibernet's assets and strong orders at the end of the year delivered revenue growth and improved margins at GCUK," said John Legere, Global Crossing's chief executive officer. "As enterprises continue shifting from legacy networks, demand for our IP-based solutions will drive GCUK and the rest of Global Crossing's business to even greater successes."

On December 28, 2006, GCUK acquired certain of the Fibernet group of companies from a subsidiary of Global Crossing Limited and began consolidating Fibernet's UK operations into its own operations; therefore, the impact of Fibernet on GCUK's operating results for the fourth quarter and full year 2006 was not significant.

Fourth Quarter Results

In the fourth quarter, GCUK generated revenue of 76 million pounds, compared with 73 million pounds in the third quarter of 2007 and 62 million pounds in the fourth quarter of 2006. The sequential increase in revenue was due to increased enterprise revenue with the addition of HMRC, as well as an increase in revenue from equipment sales. Year-over-year growth was primarily due to the inclusion of Fibernet into GCUK's operations.

Adjusted gross margin was 53 million pounds or 70 percent of revenue in the fourth quarter of 2007. This compares with 52 million pounds or 72 percent of revenue in the third quarter of 2007 and 42 million pounds or 68 percent of revenue in the fourth quarter of 2006. Excluding the third quarter benefit to cost of access arising from the reclassification of costs from cost of access to depreciation and amortization to align Fibernet's accounting policies with those of GCUK, adjusted gross margin as a percentage of revenue was flat on a sequential basis. Year-over-year growth in adjusted gross margin was due to the consolidation of Fibernet's UK operations into GCUK.

Cost of revenue, which includes cost of access, technical real estate, network and operations, third party maintenance and cost of equipment sales, was 45 million pounds for the quarter, compared with 44 million pounds in the third quarter of 2007 and 43 million pounds in the fourth quarter of 2006. The sequential increase in cost of revenue was primarily due to increases in cost of equipment sales and an increase in cost of access from the third quarter principally due to the benefit recorded in the third quarter described above. These increases were offset by a rebate in real estate, network and operations and lower third party maintenance costs. The year-over-year increase in cost of revenue was primarily due to the addition of Fibernet's UK operations, offset by lower equipment sales.

Sales, general and administrative expenses (SG&A) for GCUK were 8 million pounds in the fourth quarter, compared with 9 million pounds in the third quarter of 2007 and 9 million pounds in the fourth quarter of 2006. SG&A for the third quarter of 2007 included a restructuring charge of one million pounds related to vacating a Fibernet facility. Other expenses remained relatively flat in the fourth quarter resulting in a sequential improvement in SG&A. The year-over-year decrease in SG&A was primarily due to severance and other restructuring expense related to the acquisition of Fibernet in the fourth quarter of 2006, partially offset by higher SG&A costs due to the addition of Fibernet's UK operations.

GCUK's adjusted IFRS EBITDA for the fourth quarter was 22 million pounds, compared with 21 million pounds in the third quarter of 2007 and 19 million pounds in the fourth quarter of 2006. The fourth quarter of 2006 included an 8 million pound non-cash net gain arising from the acquisition of Fibernet. (See Table 2 notes for reference.)

The company's consolidated net loss applicable to common shareholders was 2 million pounds for the fourth quarter, compared with net profit of approximately one million pounds in the third quarter of 2007 and a net loss of 2 million pounds in the fourth quarter of 2006.

Full Year Results

GCUK generated 297 million pounds of revenue for 2007, 98 percent of which was generated from the "invest and grow" category - namely that part of the business focused on serving global enterprises and carrier customers excluding wholesale voice. This represents growth in total annual revenue of 56 million pounds, or 23 percent, compared with 2006. The growth in total annual revenue is primarily due to the addition of Fibernet's UK operations and to a lesser extent due to additional revenues from the new HMRC contract referenced above, a settlement with a certain customer, and additional revenues from new business within the carrier data channel, offset by continued attrition in the revenue base and by price reductions made available to some customers during the year.

In 2007, Camelot announced its intention to replace its existing service supplied by GCUK. As previously stated, Camelot's plans are to start migration of the network shortly. Although the precise impact on GCUK will depend on the details and timing of Camelot's actual network transition, the company has yet to see a revenue impact but expects revenue from Camelot to decline substantially through the third and fourth quarters of 2008 and the first quarter of 2009.

GCUK reported adjusted gross margin of 209 million pounds, or 70 percent, for 2007. This compares with 164 million pounds, or 68 percent of revenue, in 2006. The 45 million pounds year-over-year increase was primarily due to the addition of Fibernet's UK operations and associated savings in cost of access expense during the year.

Cost of revenue was 185 million pounds in 2007, or 62 percent of revenue, compared with 159 million pounds, or 66 percent of revenue, in 2006. The 26 million pound year-over-year increase was primarily due to the inclusion of Fibernet, an increase in cost of access due to greater enterprise and carrier sales volume, and an increase in cost of equipment sales.

SG&A expenses were 36 million pounds, or 12 percent of revenue in 2007, compared with 31 million pounds, or 13 percent of revenue, in 2006. The year-over-year increase was primarily due to the inclusion of Fibernet, increased salaries and sales commissions, retention and motivation grant expenses, and charges relating to Global Crossing's May 2007 restructuring plan.

GCUK reported 78 million pounds of adjusted IFRS EBITDA for 2007, compared with 62 million pounds of adjusted IFRS EBITDA for 2006.

The company's consolidated net loss applicable to common shareholders was 2 million pounds for 2007, compared with net income of 13 million pounds in 2006.

Cash Position

As of December 31, 2007, GCUK had 24 million pounds of cash and cash equivalents. Net cash provided from operating activities totaled less than half a million pounds after 16 million pounds of interest paid during the fourth quarter. After interest income of 2 million pounds and a use of 9 million pounds for capital expenditures and principal payments on capital leases, GCUK's net decrease in cash and cash equivalents in the fourth quarter was 6 million pounds.

Net cash provided from operating activities during 2007 totaled 14 million pounds after 34 million pounds of interest paid during the year. GCUK's net decrease in cash and cash equivalents was 16 million pounds for 2007 after capital expenditures of 40 million pounds including principal payments on capital leases.

Cost of revenue: Under U.S. GAAP, the company includes cost of access, real estate, network and operations, third party maintenance and cost of equipment sales within cost of revenue.

Net gain arising from acquisition of Fibernet: Under IFRS, the company includes the gain on settlement of contracts due to Fibernet acquisition (8,411 pounds), the gain on recognition of negative goodwill (1,050 pounds) and charges related to restructuring Fibernet's operations (1,706 pounds) in net gain arising from acquisition of Fibernet within operating profit.

(1) Initial accounting for the acquisition of Fibernet was determined only provisionally as at December 31, 2006. In accordance with IFRS 3, any adjustment to the provisional values as a result of completing the initial accounting requires adjustment of comparative financial statements. During the year ended December 31, 2007, an adjustment to increase the liabilities assumed in the acquisition was recorded which resulted in a change in the amount of negative goodwill and resulting gain recorded at the acquisition date. This adjustment has been reflected in the consolidated income statement for the year ended December 31, 2006. On October 11, 2006, GC Acquisitions, a wholly-owned subsidiary of Global Crossing Limited and affiliate of Global Crossing (UK) Telecommunications Ltd.

Global Crossing (UK) Telecommunications Limited and Subsidiaries Table 5 Reconciliation of Adjusted IFRS EBITDA to Profit (Loss) for the Period (unaudited) Results below are in pounds sterling in thousands. Three months ended Year ended December December December December 31, 2007 31, 2006 (1) 31, 2007 31, 2006 (1) (unaudited) (unaudited) (unaudited) (unaudited) Adjusted IFRS EBITDA 22,424 19,372 78,218 61,586 Non-cash stock compensation 158 41 (2,280) (217) Depreciation and amortization (10,877) (6,387) (42,161) (24,551) Finance revenue 1,608 (20) 4,527 1,503 Finance costs (10,303) (4,327) (33,548) (16,191) Taxation (4,646) (11,020) (6,297) (9,377) (Loss) profit for period (1,636) (2,341) (1,541) 12,753 Consistent with the SEC's Regulation G, the foregoing table provides a reconciliation of adjusted IFRS EBITDA, which is considered a non-GAAP (Generally Accepted Accounting Principles) financial metric, to profit (loss) for the period, which is the most directly comparable IFRS measure. Management believes that adjusted IFRS EBITDA is a relevant indicator of operating performance, especially in a capital-intensive industry such as telecommunications. Adjusted IFRS EBITDA is an important aspect of the company's internal reporting and is also used by the investment community in assessing financial performance. This non-GAAP measure should be used in addition to, but not as a substitute for, the analysis provided in the consolidated statement of operations. Definition: Adjusted IFRS EBITDA consists of profit (loss) for the period before non-cash stock compensation, taxation, finance costs, finance revenue and depreciation and amortization expense recorded to cost of sales and administrative expenses. On October 11, 2006, GC Acquisitions, a wholly-owned subsidiary of Global Crossing Limited and affiliate of Global Crossing (UK) Telecommunications Ltd. (GCUK), took control of Fibernet Group Plc (Fibernet), and since that date the results of Fibernet have been consolidated into Global Crossing's results. On December 28, 2006, GCUK acquired all of Fibernet's UK operations from GC Acquisitions. Accordingly, Fibernet's UK operation results are included in GCUK's 2006 results as of December 28, 2006. (1) Initial accounting for the acquisition of Fibernet was determined only provisionally as at December 31, 2006. In accordance with IFRS 3, any adjustment to the provisional values as a result of completing the initial accounting requires adjustment of comparative financial statements. During the year ended December 31, 2007, an adjustment to increase the liabilities assumed in the acquisition was recorded which resulted in a change in the amount of negative goodwill and resulting gain recorded at the acquisition date. This adjustment has been reflected in the consolidated income statement for the year ended as at December 31, 2006.
