USA Mobility Reports First Quarter Operating Results;
Board Declares Regular Quarterly Dividend

Wireless Subscriber and Revenue Trends Improve;
Software Business Performance on Track;
Operating Expenses Again Reduced

Springfield, VA (May 4, 2011) —USA Mobility, Inc. (Nasdaq: USMO), a leading provider ofwireless messaging,mobile voice and data andunified communications solutions, today announced operating results for the first quarter ended March 31, 2011. In addition, the Company’s Board of Directors declared a regular quarterly dividend of $0.25 per share, payable on June 24, 2011 to stockholders of record on May 20, 2011.

Total revenue for the first quarter was $57.3 million, including $52.5 million from the Company’s wireless business (USA Mobility Wireless) and $4.8 million from its software business (Amcom Software), which the Company acquired on March 3, 2011. Software maintenance revenue was reduced by $0.9 million for purchase accounting adjustments. First quarter revenue from the wireless business was $52.5 million, compared to $54.6 million in the fourth quarter and $62.8 million in the first quarter of 2010. Reported results for the software business include only the 29-day period from March 3, 2011 to March 31, 2011. On a pro forma basis, reflecting Amcom results for the full quarter and excluding purchase accounting adjustments, total revenue was $65.6 million.

First quarter EBITDA (earnings before interest, taxes, depreciation, amortization and accretion) totaled $17.9 million, including $17.0 million from wireless and $0.9 million from software. First quarter EBITDA from wireless was $17.0 million, compared to $16.9 million in the prior quarter and $22.0 million in the year-earlier quarter. On a pro forma basis, excluding purchase accounting adjustments and one-time acquisition related expenses, first quarter EBITDA was $21.7 million or 33.0 percent of revenue.

Net income for the first quarter reflected 29 days of the software business as well as the maintenance revenue purchase accounting adjustment. Also, operating expenses (excluding depreciation, amortization and accretion)

reflected $2.9 million in one-time acquisition related expenses, and depreciation, amortization and accretion increased $0.5 million due primarily to acquired intangible assets. Additionally, the acquisition resulted in a $32.4 million reduction in the deferred income tax asset valuation allowance and a corresponding reduction in income tax expense. The result was net income for the first quarter of $40.7 million, or $1.82 per fully diluted share, compared to $8.9 million, or $0.39 per fully diluted share, in the year-earlier quarter. Excluding the purchase accounting adjustment to software maintenance revenue, the one-time acquisition related expenses and the reduction in the deferred income tax asset valuation allowance, net income for the first quarter would have been $10.9 million, or $0.49 per fully diluted share

First quarter results included:

Wireless

• Net unit losses improved to 61,000 in the first quarter, compared to 83,000 in the first quarter of 2010, and the quarterly rate of unit erosion improved to 3.2 percent from 3.8 percent in the year-earlier quarter. The annual rate of subscriber erosion was 12.9 percent in the first quarter, compared to 19.5 percent in the year-ago quarter, and was the lowest annual unit loss rate in more than six years. Units in service at March 31, 2011 totaled 1,828,000, compared to 2,099,000 a year earlier.

• The quarterly rate of revenue erosion improved to 3.9 percent from 4.0 percent in the first quarter of 2010, while the annual rate of revenue erosion was 16.3 percent in the first quarter, compared to 21.2 percent in the year-earlier quarter, reaching its lowest level in two years.

• Total ARPU (average revenue per unit) was $8.72 in the first quarter, compared to $8.74 in the fourth quarter and $9.00 in the first quarter of 2010.

Software

• Pro forma bookings for the quarter ended March 31, 2011 were $13.7 million and the backlog was $19.3 million at March 31, 2011.

• Revenue from the software business totaled $4.8 million in the period from March 3, 2011 to March 31, 2011, of which $0.9 million was maintenance revenue and $3.9 million was operations revenue (which includes software, professional services and equipment sales). Pro forma revenue, excluding purchase accounting adjustments of $0.9 million, was $5.7 million for the 29-day period.

• The pro forma renewal rate for maintenance in the first quarter was 99.5 percent.

Total Company

• Operating expenses (excluding depreciation, amortization and accretion) totaled $39.5 million in the first quarter, with $35.6 million for wireless (which included $2.9 million of acquisition related expenses) and $3.9 million for software.

• EBITDA margin (or EBITDA as a percentage of revenue) was 31.2 percent. EBITDA margin for wireless was 32.3 percent, compared to 30.9 percent in the fourth quarter and 35.0 percent in the year-earlier quarter.

• Capital expenses were $1.5 million, compared to $1.7 million in the first quarter of 2010.

• The Company’s cash balance at March 31, 2011 was $23.4 million.

• The outstanding debt balance was $51.9 million at an interest rate of 5.25 percent.

Vincent D. Kelly, president and chief executive officer, said: “Consistent with financial guidance we provided earlier this year, USA Mobility continued to make excellent progress during the first quarter, meeting or exceeding key performance goals for both our wireless and software businesses. We were particularly pleased to see solid results from our recently acquired Amcom Software subsidiary, as well as continued improvement in the pace of subscriber and revenue erosion in our wireless business. At the same time, we continued to reduce expenses, maintain strong operating margins, and generate sufficient cash flow to again return capital to stockholders in the form of dividend distributions.”

Kelly said the Company continued to focus sales and marketing efforts in its wireless business during the quarter around its core market segments of Healthcare, Government and Large Enterprise. “These core segments represented approximately 88.9 percent of our direct subscriber base and 83.8 percent of our direct paging revenue at the end of the first quarter, compared to 86.8 percent and 81.5 percent, respectively, a year earlier. Healthcare continued to be our best performing market segment with the highest rate of gross placements and lowest rate of net unit loss as healthcare providers continue to benefit from the reliability of paging for their most critical messaging needs.”

Commenting on the software business, Kelly said: “Our integration of Amcom is on track and going exceptionally well. To date we have initiated training programs for both sales teams to share leads and cross sell products and services into our key market segments, especially Healthcare. Additionally, we have received very positive feedback from our healthcare customer base with respect to the merger and its impact on our future. Moving forward we expect to leverage additional operational capabilities from each business, including customer relationships, technical know-how, and back-office support. Despite the distraction of the acquisition in the first quarter,” Kelly noted, “our software business generated strong bookings and has a $19.3 million backlog going into the second quarter.”

Shawn E. Endsley, chief financial officer, said the Company continued to reduce operating expenses in the first quarter. “Recurring operating expenses (excluding depreciation, amortization and accretion) for wireless decreased

20.0 percent from the year-earlier quarter,” Endsley noted, “exceeding the rate of wireless revenue decline. At the same time, ARPU remained strong and capital expenses declined. With respect to Amcom,” Endsley added, “the addition of software operations required a review of the recovery of our deferred income tax assets. The expected additional taxable income from Amcom allowed for a reduction in the deferred income tax asset valuation allowance and income tax expense of $32.4 million. Including software operations from March 3, 2011, the combined businesses generated operating cash flow of $12.7 million in the quarter.”

Regarding financial guidance for 2011, Endsley said the Company is reiterating its prior guidance for the full year for the wireless company as well as its full year pro-forma guidance for the software company. Additionally, the software company guidance for financial reporting purposes has been broken out separately in the schedules attached to this press release and has been adjusted to reflect: (1) results for the partial year (March 3 to December 31); and (2) purchase accounting adjustments for deferred revenue. As such, Endsley said the Company expects total revenues for 2011 to range from $224 million to $240 million, with wireless between $182 million and $192 million and software between $42 million and $48 million; operating expenses (excluding depreciation, amortization and accretion) to range from $167 million to $176 million, with wireless between $132 million and $136 million and software between $35 million and $40 million; and capital expenses to range from $6 million to $9 million, with wireless between $5 million and $7 million and software between $1 million and $2 million.
