As of December 31, 2011, the Company was authorized to repurchase up to 1.7 million additional shares.

“Tyler’s strong fourth-quarter financial performance builds upon a trend of improving results that began in the second quarter as the market started to show signs of modest improvement,” said John S. Marr Jr., Tyler’s president and chief executive officer. “By many measures, our fourth-quarter results are the best we’ve ever reported. We achieved double-digit revenue growth driven by continued solid growth in recurring revenues from subscriptions and maintenance. We’re also pleased that software license revenue grew year-over-year for the first time since the fourth quarter of 2009. In addition, our gross margin of 47.5 percent represents a new quarterly high.

“New contract signings in the fourth quarter, which included a contract with the state of Maryland valued at approximately $45 million for our Odyssey^® court management system, were very good,” said Mr. Marr. “Tyler enters 2012 with a record backlog of signed contracts and a very active sales pipeline. We are cautiously optimistic that market conditions will continue to improve in 2012, and with Tyler’s strong competitive position our outlook for the coming year is positive.”

Non-GAAP Measures

This press release discloses the financial measures of EBITDA and free cash flow. These financial measures are not prepared in accordance with generally accepted accounting principles (GAAP) and are therefore considered non-GAAP financial measures. The non-GAAP measures should be considered in addition to, and not as a substitute for, or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. The non-GAAP measures used by Tyler Technologies may be different from non-GAAP measures used by other companies. We believe the presentation of these non-GAAP financial measures provides useful information to users of our financial statements and is helpful to fully understand our past financial performance and prospects for the future. We believe EBITDA and free cash flow are widely used by investors, analysts, and other users of our financial statements to analyze operating performance, provide meaningful comparisons to prior periods and to compare our results to those of other companies, and they provide a more complete understanding of our underlying operational results and trends, as well as our marketplace performance and our ability to generate cash. In addition, we internally monitor and review these non-GAAP financial measures on a consolidated basis as some of the primary indicators management uses to evaluate Company performance and for planning and forecasting future periods. Therefore, management believes that EBITDA and free cash flow provide meaningful supplemental information to the investor to fully assess the financial performance, trends and future prospects of Tyler’s core operations.
