DALLAS – Oct. 24, 2012 – Tyler Technologies, Inc. (NYSE: TYL) today announced financial results for the quarter ended September 30, 2012. Total revenue grew 21.6 percent to $93.8 million and net income was $10.8 million, or $0.33 per diluted share. In the same quarter last year, the Company had revenue of $77.2 million and net income of $7.5 million, or $0.23 per diluted share. Gross margin increased 110 basis points to 47.9 percent compared to 46.8 percent in the year-ago quarter.

Recurring software revenue from maintenance and subscriptions was $55.8 million in the third quarter of 2012, an increase of 24.0 percent compared to the third quarter of 2011, and comprised 59.4 percent of the quarter’s total revenue.

Excluding capital expenditures associated with real estate, free cash flow for the third quarter of 2012 was $32.9 million compared to $24.3 million in the third quarter of last year. Including real estate capital expenditures, free cash flow for the current quarter was $31.8 million compared to $24.3 million for the same period in 2011.

EBITDA, or earnings before interest, income taxes, depreciation and amortization, increased 45.9 percent to $21.6 million in the third quarter of 2012, compared to $14.8 million in the prior-year quarter.

Total backlog was $357.9 million at September 30, 2012, up 19.8 percent from $298.7 million at September 30, 2011. Software-related backlog (excluding appraisal services) reached a new high of $328.2 million, an increase of 18.3 percent compared to $277.5 million at September 30, 2011.

“Tyler achieved exceptional results for the quarter, returning organic revenue growth of over 13 percent and together with revenues from our recent acquisitions, total growth of over 21 percent from the same period last year. We are encouraged that all of our software-related revenue lines, and particularly our recurring revenues, experienced strong double-digit growth,” said John S. Marr Jr., Tyler’s president and chief executive officer. “Tyler’s gross margin of 47.9 percent and operating profit margin of almost 20 percent were both new quarterly highs.

“Bookings in the third quarter increased 15 percent over last year, continuing a trend of improvement that reflects both improved market conditions and our strong competitive position. In addition, our new business pipeline remains very active, with volume near historically high levels,” said Mr. Marr. “Our revenue and earnings guidance is consistent with that issued earlier in the year, with the ranges narrowed slightly to reflect our current expectations for the mix of new business between SaaS and deployed license contracts.”

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.
