Exhibit 99 TCS Reaffirms Second Quarter Outlook Company Expects Over $40 Million Revenue and Positive Net Income for the Quarter ANNAPOLIS, Md., June 30 /PRNewswire-FirstCall/ -- TeleCommunication Systems, Inc. (Nasdaq: TSYS), a global leader in wireless data technology, today announced it expects results for the quarter to be above the midpoint of the range of revenues and net income previously announced by the company: revenues between $38 and $42 million, and GAAP earnings per share between minus 3 and plus 5 cents per share. "Following a seasonally low first quarter for Government segment revenue, the company had very strong government orders and systems deliveries during the three months now ending," commented Maurice B. Tose, Chairman, President and CEO for TCS. "In addition, strong growth in our wireless carrier customers' usage of TCS text messaging technology generated significant license revenue for added capacity." "This will represent the third of four quarters that our company has reported positive GAAP net income (after deducting all noncash charges, which have approximated 10 cents a share per quarter in 2004.) With a growing order book for wireless carrier location-based software systems and the momentum in our Government segment, the company expects continued quarter over quarter improvement in performance during the balance of 2004. As we indicated at the beginning of the year, we intend to achieve overall revenue of $150 to $170 million for 2004, with per share net income of 12 to 18 cents a share." TCS cautioned that these anticipated results are based on the best information currently available, and are subject to change and the closing of the books and customary quarterly and yearly accounting procedures. The quarter end earnings release and investor conference call are tentatively scheduled for July 29; a press release announcing details for the call will be made in advance.
