Brian Miller
Executive Vice President, Chief Financial Officer and Treasurer at Tyler Technologies
Thanks, Lynn. Yesterday, Tyler Technologies reported its results for the first quarter ended March 31, 2022. In our earnings release, we've included non-GAAP measures that we believe facilitate understanding of our results and comparisons with peers in the software industry. A reconciliation of GAAP to non-GAAP measures is provided in our earnings release. We've also posted on the Investor Relations section of our website under the Financial Reports tab, schedules with supplemental information provided on this call, including information about quarterly bookings, backlog and recurring revenues. Both GAAP and non-GAAP revenues for the quarter were $456.1 million, up 54.7%, with the inclusion of NIC and our other acquisitions from the last 12 months.
Organic revenue growth was the highest since Q4 of 2016 at 12.8%. Software licenses and services grew 24.7% or 3.7%, excluding NIC. Subscription revenues rose 139.5% with very strong organic growth of 33.8%. We added 149 new subscription-based arrangements and converted a new high of 88 existing on-premises clients, representing approximately $76 million in total contract value. In Q1 of last year, we added 84 new subscription-based arrangements and had 39 on-premises conversions, representing approximately $52 million in total contract value. Our software subscription bookings in the first quarter added $16.2 million in new ARR. Subscription contract value comprised approximately 80% of the total new software contract value signed this quarter, compared to 66% in Q1 of last year, reflecting our ongoing shift to a cloud-first approach to sales and increasing client preferences for cloud-based solutions. The value weighted average term of new SaaS contracts this quarter was 3.4 years compared to 4.0 years last year. Transaction-based revenues, which include NIC portal, payment processing, and e-filing revenues, and are included in subscriptions, were $152.9 million, up 461%. Excluding NIC, Tyler's transaction-based revenues grew 9.8%. E-filing revenues reached a new high of $18.2 million, up 16.9%.
For the first quarter, our non-GAAP ARR was approximately $1.45 billion, up 63.6%. Non-GAAP ARR for SaaS software arrangements was approximately $378.1 million, up 25.1%. Transaction-based ARR was approximately $603.7 million, up 461%. And non-GAAP maintenance ARR was down slightly at approximately $468.1 million, due to the continued migration of on-premises clients to the cloud. Our backlog at the end of the quarter was $1.76 billion, up 13.8%. Because the vast majority of NIC's revenues are transaction-based, their backlog at quarter end was only $26.3 million. Excluding the addition of NIC, Tyler's backlog grew 12.1%. Bookings in the quarter were strong at approximately $419 million, up 70.1%, including the transaction-based revenues at NIC. On an organic basis, bookings were also quite robust at approximately $283 million, up 14.7%. For the trailing 12 months, bookings were approximately $1.9 billion, up 65%, and on an organic basis were approximately $1.4 billion, up 21.7%. If our weighted average contract term for new SaaS contracts has been the same as last year, organic bookings growth would have been 17.1%.
Cash from operations declined this quarter by 25.3% to $53.5 million, mainly due to changes in working capital related to higher payments of accrued incentive compensation and cash tax payments related to stock-based compensation. Free cash flow declined by 33.5% to $41 million due to the decrease in cash from operations and somewhat higher capital spending this quarter. Our balance sheet remains very strong. During the quarter, we repaid $20 million of our term debt. And since completing the NIC acquisition, we have paid down $415 million of term debt. We ended the quarter with total outstanding debt of $1.32 billion and cash and investments of $322.6 million and net leverage of approximately 2.1 times trailing 12-month pro forma EBITDA. As Lynn mentioned earlier, we're off to a great start in 2022, resulting in an improvement in our outlook for the full year. As a result, we have raised our 2022 annual revenue and earnings guidance as follows. We expect both GAAP and non-GAAP total revenues will be between $1.835 billion and $1.87 billion. The midpoint of our guidance implies organic revenue growth of approximately 9.5%. We expect total revenues will include approximately $40 million of COVID-related revenues from NIC's TourHealth and pandemic rent relief services.
The TourHealth revenues are currently expected to continue through the second quarter of 2022, while revenues from the rent relief program are expected to continue through the third quarter. We expect GAAP diluted EPS will be between $3.92 and $4.08 and may vary significantly due to the impact of stock incentive awards on the GAAP effective tax rate. We expect non-GAAP diluted EPS will be between $7.48 and $7.64. Based on updated assumptions regarding additional interest rate hikes this year, we have increased our estimated interest expense for the year by $3.4 million to $23 million, with an impact on non-GAAP diluted EPS of approximately $0.06 a share. Other details of our guidance are included in our earnings release. Finally, before I turn the call back to Lynn, I'd like to announce that Hala Elsherbini will be joining Tyler as Senior Director of Investor Relations, effective May 9.
Many of you have worked with Hala in the past, and we're very excited to have an IR professional with Hala's experience and knowledge of Tyler join our team. Lynn?
