Dallas, April 27, 2009 — Tyler Technologies, Inc. (NYSE: TYL) today reported the following financial results for the quarter ended March 31, 2009:

• Free cash flow was $9.9 million (cash provided by operating activities of $12.2 million minus capital expenditures of $2.3 million), versus free cash flow of $16.9 million (cash provided by operating activities of $17.8 million minus capital expenditures of $891,000) for the same period last year. Capital expenditures for the three month period ended March 31, 2009 include $1.5 million related to construction expenditures on a new office building for one of Tyler’s divisions.

• EBITDA, or earnings before interest, income taxes, depreciation and amortization, increased 62.6 percent to $12.3 million. EBITDA for the first quarter of 2008 totaled $7.6 million.

• Share-based compensation expense for the first quarter under FAS 123R totaled $1.1 million, of which $120,000 was included in cost of revenues and $1.0 million was included in selling, general and administrative expenses. For the first quarter of 2008, share-based compensation expense was $716,000, of which $69,000 was included in cost of revenues and $647,000 was included in selling, general and administrative expenses.

• Total backlog was $231.3 million at March 31, 2009, compared to $242.4 million at March 31, 2008. Software-related backlog (excluding appraisal services) was $206.4 million at March 31, 2009 versus $217.8 at March 31, 2008.

• Tyler ended the first quarter of 2009 with $11.1 million in cash and investments and $17.5 million of availability under its $25 million revolving line of credit. During the quarter, the Company repurchased 707,100 shares of its common stock at an aggregate purchase price of $8.8 million and used $525,000 in cash for an acquisition during the quarter.

“We are pleased to report a strong start to the year with solid results in the first quarter of 2009,” commented John S. Marr, Jr., Tyler’s President and Chief Executive Officer. “With double-digit growth in each of our software-related revenue lines, including a 29 percent increase in software licenses, our competitive position remains very strong. Our organic growth of 15% was supplemented by 2% growth from acquisitions completed in the last year. Tyler’s gross margin improvement, which reflects the operating leverage in our business as well as the elimination of a significant portion of our software amortization expense, was combined with SG&A expenses that grew in line with revenues. As a result, we more than doubled last year’s first quarter operating income and earnings per share, even as we increased our investment in research and development.

“Tyler’s first quarter free cash flow of approximately $9.9 million, including capital expenditures of $1.5 million related to the construction of an office facility, exceed GAAP net income but was lower than in the same period last year primarily due to unusually favorable billing terms on certain large contracts in the first quarter of 2008,” noted Mr. Marr. “We used cash generated from operations during the quarter to repurchase over 707,000 shares of our stock, as well as for the acquisition of PulseMark, LLC.

“Broad economic conditions and the related effects on local government budgets remain a concern, and we are closely monitoring market conditions and the potential impact on our business, especially in the second half of the year. While we have not seen a significant effect on our results to date, the leading indicators that we follow are somewhat mixed, and our current annual guidance for 2009 is unchanged from that provided earlier this year,” Mr. Marr continued.

Total revenues for 2009 are currently expected to be in the range of $292 million to $298 million. Tyler expects to have diluted earnings per share of approximately $0.66 to $0.72.

Tyler expects that free cash flow for the year 2009 will be between $28 million and $36 million (cash provided by operations of $43 million to $50 million minus capital expenditures of between $14 million and $16 million). Excluding estimated real estate capital expenditures of approximately $11 million, free cash flow for 2009 is expected to be between $39 million and $47 million.

Non-GAAP Measures:

This press release discloses the financial measures of EBITDA and free cash flow.

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.

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.
