MTS Announces First Quarter 2006 Financial Results

Thursday May 11, 7:30 am ET

RA'ANANA, Israel, May 11 /PRNewswire-FirstCall/ -- MTS - Mer Telemanagement
Solutions Ltd. (Nasdaq: MTSL - News), a global provider of business support
systems for comprehensive telecommunication management and customer care &
billing solutions, today reported its financial results for the first quarter of
2006, ended March 31, 2006.

Revenues for the first quarter were $2.8 million, which represents a 3% increase
over the $2.7 million reported in the first quarter of 2005.

Net loss for the quarter was $485,000 ($0.08 basic and diluted net loss per
ordinary share), which compares to the net loss of $2.0 million ($0.44 basic and
diluted net loss per ordinary share), reported for the first quarter of 2005.
The net loss narrowed year-over-year due to a reduction in total operating
expenses.

MTS ended the first quarter with a solid, accumulated backlog of orders of
approximately $2.7 million. The backlog represents orders booked but not yet
recognized as revenue as of March 31, 2006.

Eytan Bar, President and Chief Executive Officer commented, "During the first
quarter, MTS once again executed on its business strategy and capitalized on new
opportunities. We continued to cultivate business relationships and added new
partners in Europe, as well as gained market recognition with our customer care
and billing solution.

"MTS also continued to invest significantly in its future according to the
company's strategy. We continue to believe this investment is crucial to the
success of MTS, as these enhancements and new products will give us leverage in
market share and sales, and ultimately drive toward sustainable growth."

At the end of the first quarter of fiscal year 2006, MTS implemented the
Statement of Financial Accounting Standard No. 123(R), "Share-based Payments,"
which requires expensing the fair value of grants made under stock option
programs over the vesting period of the options beginning on January 1, 2006.

Shlomi Hagai, Corporate COO & CFO, noted, "We continued to deliver solid top
line performance in the first quarter despite unanticipated extended sales
cycles in some of the markets in which we participate. We believe that our
commitment to monitor and maintain expenses will allow us to continue to improve
our bottom line performance going forward."
