Third Quarter Financial Highlights:

“Tyler achieved exceptional results for the third quarter, with our second consecutive quarter of revenue growth greater than 20 percent and non-GAAP net income growth greater than 40 percent,” said John S. Marr Jr., Tyler’s president and chief executive officer. “All of our software-related revenue lines delivered double-digit growth, including 26 percent growth in software license and royalty revenues and 49 percent growth in subscriptions.

“Our record earnings have also generated record cash flow thus far in 2014. For the third quarter, Tyler’s cash flow from operations of $66.3 million actually exceeded our full-year 2013 cash flow from operations. We ended the quarter with cash of more than $157 million, and the strength of our balance sheet positions us well to take advantage of future growth opportunities.

“Tyler followed our record bookings in the second quarter of this year with another very good quarter for new contract signings, which illustrates our strong competitive position and resulting high win rates. Excluding the eFileTexas contract signed in last year’s third quarter, our bookings rose nearly 5 percent for the quarter, and 22 percent for the trailing 12 months. New contract signings were solid across product lines and in both our on-premises and cloud-based offerings.

“We have a sharp focus on executing at a high level with respect to sales, implementations and client support to continue to build on our considerable strengths in the market. With the results achieved in the first three quarters of 2014, combined with our continued positive outlook for the fourth quarter, we have again revised upward our revenue and earnings guidance,” Mr. Marr concluded.

Non-GAAP Financial Measures

Tyler Technologies has provided in this press release financial measures that have not been prepared in accordance with generally accepted accounting principles (GAAP) and are therefore considered non-GAAP financial measures. This information includes non-GAAP gross profit, non-GAAP gross margin, non-GAAP operating income, non-GAAP operating margin, non-GAAP net income, non-GAAP earnings per diluted share, EBITDA and adjusted EBITDA. We use these non-GAAP financial measures internally in analyzing our financial results and believe they are useful to investors, as a supplement to GAAP measures, in evaluating Tyler’s ongoing operational performance. Tyler believes the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing our financial results with other companies in our industry, many of which present similar non-GAAP financial measures. Non-GAAP financial measures discussed above exclude share-based compensation expense, employer portion of payroll taxes on employee stock transactions, and expenses associated with amortization of intangibles arising from business combinations. We use these measures and believe they are useful to investors because they provide additional insight in comparing results from period to period.

Non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial information prepared in accordance with GAAP. The non-GAAP measures used by Tyler Technologies may be different from non-GAAP measures used by other companies. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures, which has been provided in the financial statement tables included below in this press release.
