USA Mobility Reports Preliminary 2005 Operating Results

First Year Marked by Successful Merger Integration,
Repayment of Debt and Return of Capital to Shareholders

Alexandria, VA (Apri1 3, 2006) — USA Mobility, Inc. (Nasdaq: USMO), a leading provider of wireless messaging services, today announced preliminary and unaudited operating results for the fourth quarter and year ended December 31, 2005, its first full year of operations following the merger between Arch Wireless, Inc. and Metrocall Holdings, Inc. on November 16, 2004.

The company announced on March 31, 2006 that it delayed the filing of its 2005 Form 10-K and its amended Form 10-K/A for the year ended December 31, 2004, and amended Form 10-Q/A’s for the three interim quarterly periods for 2004 and 2005. The delay was the result of unforeseen time requirements in connection with completing its restatements of income taxes and deferred tax assets for the years 2003 and 2004, and interim periods of 2004 and 2005. The company is working diligently on completing this work and intends to file these statements as soon as practicable.

Upon completion of the audit and related filings, USA Mobility expects to report the following results: revenue of $618.6 million for 2005, with EBITDA of $155.9 million, or 25 percent of revenue; and operating income for 2005 of $2.5 million, as the company accelerated depreciation of the former Arch two-way paging system. Decommissioning of the system was completed in the fourth quarter of 2005. Additionally, the company recorded operating expenses in 2005 of $16.6 million for severance and contract termination costs associated with the integration of Arch and Metrocall.

The company said the merger integration, which is substantially complete, was the catalyst for significant improvements in 2005 operating results for the combined company.

Highlights of 2005 included:

• The company completed a new long-term contract with its largest tower landlord. In addition, subsequent to year end and effective January 1, 2006, the company completed a long-term contract with its second largest landlord. These contracts are expected to provide substantial cost savings compared to its previous site rent expense.

• In the fourth quarter of 2005, the company completed its planned decommissioning of the former Arch two-way paging system. The process included the decommissioning of more than 2,100 transmitters and will ultimately result in $21 million of annual savings by 2009 when all lease commitments expire.

• The company made substantial progress in rationalizing its one-way paging systems, decommissioning approximately 1,200 one-way transmitters during the year.

• Through new landlord contracts and network rationalization the company expects to reduce its total annual site rent expense $87 million, or 70 percent, by 2010.

• Integration and consolidation efforts reduced the number of employees from more than 2,800 at the time of the merger to 1,617 at December 31, 2005. This 43 percent reduction in workforce unlocked significant improvement in revenue per employee, which had been decreasing for both Arch and Metrocall over the four quarters leading up to the merger. Since the merger, revenue per employee has increased 40 percent and reached $343,000 of annualized revenue per employee as of the fourth quarter of 2005.

• The company streamlined its sales organization from three divisions, which included 15 regions, to a single nationwide sales organization with 11 regions. The consolidation included a significant reduction in management overhead.

• In total, all integration and cost consolidation efforts reduced the company’s operating expense, excluding depreciation and amortization, by $41.6 million per quarter, from $144.4 million on a pro-forma basis in the fourth quarter of 2004, to $102.8 million in the fourth quarter of 2005.

• The company repaid $140 million in debt, which it incurred to consummate the merger, within the first nine months of operations.

• The company paid a $1.50 per share dividend in December 2005, representing a $41 million return of capital to its investors.

• The company began exploring alternative revenue sources, including the execution of an agreement with Advanced Metering Data Systems (AMDS) in which USA Mobility would share revenue derived from its narrowband PCS meter reading network.

• USA Mobility strengthened and enhanced its executive management team, including the recruitment of its chief financial officer, general counsel and executive vice president for marketing, as well as filled the positions of chief operating officer and executive vice president of sales through internal promotions.

In addition to the benefits of the merger and subsequent integration, the company also experienced improved revenue and subscriber trends during 2005.

• The rate of revenue erosion continued to show improvement. In all four quarters since the merger the year-over-year rate of revenue decline improved on a pro-forma basis from 22.7 percent in first quarter, 22.4 percent in second quarter, 20.6 percent third quarter and finally to 20.3 percent in the fourth quarter.

• The quarterly loss in subscribers slowed significantly from over 500,000 in the first quarter of 2004 on a pro-forma basis to 230,000 in the fourth quarter of 2005. More importantly, the quarterly rate of erosion declined from 6.5 percent to 4.5 percent during the same period.

“We made excellent progress in our first year following the merger,” said Vincent D. Kelly, president and chief executive officer. “We substantially integrated the nation’s two largest paging carriers, achieving significant synergies and operational costs savings.” Kelly added: “In addition, while the paging and wireless messaging sector remains challenging, we were encouraged by the improvement in subscriber erosion during the year as well as the improving trends in the pace of revenue decline. As we move forward to complete the integration process and implement new sales and marketing initiatives in 2006, we anticipate even further financial and operational improvements that will allow us to better meet the needs of our customers nationwide.”

Thomas L. Schilling, chief financial officer, said: “We continued to strengthen our financial position since the merger. We significantly reduced our operating costs, paid off $140 million in debt, paid out $41 million in dividends and ended the year with $37.5 million in cash, and expect to end the first quarter of 2006 with a cash balance of approximately $73 million.” Schilling also outlined the company’s guidance for 2006, stating: “In 2006 the company expects revenue to be in a range from $480 million to $500 million, operating expenses, excluding depreciation and amortization, are expected to be in a range from $370 million to $380 million, and capital expenses in a range from $15 million to $20 million.”
