Metrocall Reports Second Quarter 2004 Operating Results

Company Reports Revenues of $87.1 Million, Progress with WebLink Integration
and Continued Reduction in Operating Expenses

     Alexandria, VA, Friday, August 6, 2004 — Metrocall Holdings, Inc. (NASDAQ: MTOH), a leading provider of paging and wireless messaging services, today announced total revenues for the second quarter of 2004 of $87.1 million and net income of $7.2 million for the quarter compared to revenues of $90.7 million and net income of $7.5 million for the first quarter of 2004. On May 17, 2004 Metrocall redeemed the remaining $6.8 million aggregate liquidation balance of its series A preferred (series A) stock outstanding. As of June 30, 2004 Metrocall had cash and cash equivalents of $26.7 million, compared to $14.7 million on March 31, 2004.

     Metrocall Wireless President & CEO Vince Kelly stated, “Metrocall’s free cash flow-based business strategy over the past year and a half enabled us to achieve another important milestone in the second quarter, the redemption of the balance of our series A preferred stock, satisfying a closing condition to our Arch merger transaction and marking the full retirement of all long-term debt and series A obligations well ahead of the schedule specified in our 2002 Plan of Reorganization. We continue to focus on our improving retention of our direct subscriber base, which lost fewer subscribers during the quarter as compared to the first quarter. The majority of our subscriber attrition was in the indirect channels, as opposed to our higher RPU direct base, the channel that generates the majority of the Company’s revenues.”

     Metrocall reported 3,003,391 ending subscribers for the quarter ended June 30, 2004, representing a reduction of 222,031 as compared to March 31, 2004. This reduction was comprised of 205,961 traditional units and 16,070 advanced messaging (two-way) units. Average revenue per unit in service was $7.42 for traditional and $18.17 for advanced messaging, representing an increase of $0.18 and a decrease of $0.52 per unit, respectively from the three months ended March 31, 2004.

     Metrocall’s direct base (which includes both one-way paging and two-way paging) was reduced by 72,442 subscribers during the second quarter, as opposed to the 90,871 direct subscribers lost during the first quarter. Metrocall’s indirect base (which also includes both one-way paging and two-way paging) was reduced by 149,589 subscribers during the second quarter, compared to 148,651 subscribers during the first quarter. Of the subscriber unit reduction between the first and second quarters of 2004, approximately 67.4% and 32.6% were from the indirect and direct channels respectively, compared to 62.1% and 37.9% between the fourth quarter of 2003 and the first quarter of 2004. RPU for the direct channel was $11.19 in the second quarter vs. $11.44 in the first quarter. RPU for the indirect channel was $2.84 in the second quarter vs. $2.28 in the first quarter.

     Overall, compared to first quarter results, the second quarter 2004 total revenue loss was $3.6 million or 4%.

     Operating expenses including, cost of products sold, service, rent and maintenance, selling and marketing and general and administrative expenses (but excluding stock-based, depreciation and amortization expenses) for the second quarter of 2004 totaled approximately $62.6 million compared to $64.4 million reported for the first quarter. Operating expenses however included approximately $3.0 million in the second quarter and $1.1 million for the first quarter in general and administrative expenses related to legal and other expenses associated with the proposed merger between Metrocall and Arch Wireless, Inc.

     Overall operating expenses, independent of costs incurred for the Metrocall/Arch merger preparation, were reduced by approximately $3.7 million or 5.8%, and capital expenditures of $3.9 million were 18% lower.

     Kelly further stated, “Metrocall’s integration of the former assets of WebLink Wireless, acquired in November 2003, influenced second quarter operating results and further cost containment targets are expected to be achieved as the integration nears completion in the months ahead. Metrocall paid $2.4 million in income tax estimates during the quarter and expects to pay in a range of $9.0 million to $11.0 million for 2004. During the quarter we also continued to make significant progress on planning for the integration of Metrocall and Arch.”

     The Company reported basic and diluted earnings per share of $1.30 and $1.24 respectively compared to basic and diluted earnings per share of $1.38 and $1.31, respectively for the quarter ended March 31, 2004.

     On March 29, 2004, Metrocall announced the execution of a definitive merger agreement with Arch Wireless, Inc. A new holding company, USA Mobility, Inc., has been formed to own both Arch and Metrocall. Under terms of the agreement, Arch and Metrocall shareholders will own approximately 72.5% and 27.5% of USA Mobility, Inc., respectively and Metrocall shareholders will also receive $150 million in cash for 2 million shares of Metrocall common stock.
