Tyler Technologies Reports Earnings
For Third Quarter 2011

Quarterly revenue and backlog reach new highs

DALLAS — Oct. 26, 2011 — Tyler Technologies, Inc. (NYSE: TYL) today announced financial results for the quarter ended September 30, 2011. Tyler reported total revenue of $77.2 million and net income of $7.5 million, or $0.23 per diluted share. In the same quarter last year, the Company had revenue of $73.8 million and net income of $6.7 million, or $0.19 per diluted share. Gross margin increased 180 basis points to 46.8 percent compared to 45.0 percent in the year-ago quarter.

Recurring software revenue from maintenance and subscriptions was $45.0 million in the third quarter of 2011, an increase of 10.4 percent compared to the third quarter of 2010, and comprised 58.3 percent of the quarter’s total revenue.

Free cash flow for the third quarter of 2011 was $24.3 million (cash provided by operating activities of $25.8 million minus capital expenditures of $1.5 million) compared to $26.9 million (cash provided by operating activities of $27.6 million minus capital expenditures of $0.7 million) in the third quarter of last year.

EBITDA, or earnings before interest, income taxes, depreciation and amortization, was $14.8 million in the third quarter of 2011, compared to $14.3 million in the prior-year quarter.

Total backlog was a record high $298.7 million at September 30, 2011, up 17.7 percent from $253.8 million at September 30, 2010. Software-related backlog (excluding appraisal services) was $277.5 million, an increase of 28.4 percent compared to $216.2 million at September 30, 2010.

Tyler ended the third quarter of 2011 with $7.4 million in cash and investments and $83.7 million of availability under its $150.0 million revolving line of credit. During the third quarter, Tyler repurchased approximately 2.0 million shares of its common stock at an average price of $24.34 per share. As of September 30, 2011, the Company was authorized to repurchase up to 1.8 million additional shares.

“We are pleased by our results in the third quarter, which by many measures was our best quarter ever, particularly in a market that remains challenging. Although software license revenues remain weak, we continue to drive solid growth in recurring revenues from maintenance and subscriptions. In addition, our software services revenues grew for the first time in seven quarters,” said John S. Marr Jr., Tyler’s president and chief executive officer. “The leverage in our recurring revenues was reflected in our gross margin, which reached a new all-time high at 46.8 percent.”

“Bookings in the third quarter were good, pushing our backlog to a new high, and our new-business pipeline remains active with what appears to be a modest increase in market activity,” said Mr. Marr. “Although the market is certainly less than robust and the timing and mix of new business is somewhat unpredictable, our competitive position is strong and our current guidance for the year reflects an improvement from our prior outlook.”

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.

This document contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 that are not historical in nature and typically address future or anticipated events, trends, expectations or beliefs with respect to our financial condition, results of operations or business. Forward-looking statements often contain words such as “believes,” “expects,” “anticipates,” “foresees,” “forecasts,” “estimates,” “plans,” “intends,” “continues,” “may,” “will,” “should,” “projects,” “might,” “could” or other similar words or phrases. Similarly, statements that describe our business strategy, outlook, objectives, plans, intentions or goals also are forward-looking statements. We believe there is a reasonable basis for our forward-looking statements, but they are inherently subject to risks and uncertainties and actual results could differ materially from the expectations and beliefs reflected in the forward-looking statements. We presently consider the following to be among the important factors that could cause actual results to differ materially from our expectations and beliefs: (1) changes in the budgets or regulatory environments of our customers, primarily local and state governments, that could negatively impact information technology spending; (2) our ability to achieve our financial forecasts due to various factors, including project delays by our customers, reductions in transaction size, fewer transactions, delays in delivery of new products or releases or a decline in our renewal rates for service agreements; (3) economic, political and market conditions, including the recent global economic and financial crisis, and the general tightening of access to debt or equity capital; (4) technological and market risks associated with the development of new products or services or of new versions of existing or acquired products or services; (5) our ability to successfully complete acquisitions and achieve growth or operational synergies through the integration of acquired businesses, while avoiding unanticipated costs and disruptions to existing operations; (6) competition in the industry in which we conduct business and the impact of competition on pricing, customer retention and pressure for new products or services; (7) the ability to attract and retain qualified personnel and dealing with the loss or retirement of key members of management or other key personnel; and (8) costs of compliance and any failure to comply with government and stock exchange regulations. A detailed discussion of these factors and other risks that affect our business are described in our filings with the Securities and Exchange Commission, including the detailed “Risk Factors” contained in our most recent annual report on Form 10-K. We expressly disclaim any obligation to publicly update or revise our forward-looking statements.
