In addition, we provide digital government services and payment solutions.

MARKET OVERVIEW

The state and local government market is one of the largest and most decentralized IT markets in the country, consisting of all 50 states, approximately 3,000 counties, 36,000 cities and towns and 12,900 school districts. This market is also comprised of approximately 38,000 special districts and other agencies, each with specialized delegated responsibilities and unique information management requirements.

Traditionally, local government bodies and agencies performed state-mandated duties, including property assessment, record keeping, road maintenance, law enforcement, administration of election and judicial functions, and the provision of welfare assistance. Today, a host of emerging and urgent issues are confronting local governments, each of which demands a service response. These areas include criminal justice and corrections, administration and finance, public safety, health and human services, planning, regulatory and maintenance and records and document management. Transfers of responsibility from the federal and state governments to county and municipal governments and agencies in these and other areas also place additional service and financial requirements on these local government units. In addition, constituents of local governments are increasingly demanding improved service and better access to information from public entities. As a result, local governments recognize the increasing value of information management systems and services to, among other things, improve revenue collection, provide increased access to information, and streamline delivery of services to their constituents. Local government bodies are now recognizing that “e-government” is an additional responsibility for community development. From integrated tax systems to integrated civil and criminal justice information systems, many counties and cities have benefited significantly from the implementation of jurisdiction-wide systems that allow different agencies or government offices to share data and provide a more comprehensive approach to information management. Many city and county governmental agencies also have unique individual information management requirements, which must be tailored to the specific functions of each particular office.

Many local governments also have difficulties attracting and retaining the staff necessary to support their IT functions. As a result, they seek to establish long-term relationships with reliable providers of high quality IT products and services such as Tyler.

Although local governments often face budgetary constraints in their operations, their primary revenue sources are usually property taxes, and to a lesser extent, utility billings and other fees, which historically tend to be relatively stable. In addition, the acquisition of new technology typically enables local governments to operate more efficiently, more securely, and often provides a measurable return on investment that justifies the purchase of software and related services.

Gartner, Inc., a leading information technology research and advisory company, estimates that state and local government application and vertical specific software spending will grow from $23.6$27.8 billion in 20222023 to $32.3$40.0 billion in 2025.2026. The professional services and support segments of the market are expected to expand from $32.0$33.5 billion in 20222023 to $38.4$41.9 billion in 2025.2026. Application and vertical specific software sales in the primary and secondary education segments of the market is expected to expand from $4.9$5.4 billion in 20222023 to $6.0$6.6 billion in 20252026 while professional services and support are expected to grow from $5.1 billion in 20222023 to $6.3$6.1 billion in 2025.2026. For the national and international government markets, application and vertical specific software sales is expected to expand from $38.5$42.2 billion in 20222023 to $53.8$61.5 billion in 20252026 while professional services and support are expected to grow from $63.1$65.6 billion in 20222023 to $74.4$82.1 billion in 2025.2026.

PRODUCTS AND SERVICES

We provide a comprehensive and flexible suite of products and services that addresses the information technology needs of cities, counties, states, schools, federal agencies, and other government entities.

We design, develop, market and support a broad range of software solutions to serve mission-critical “back-office” functions of the public sector. Many of our software applications include Internet-accessible solutions that allow for real-time public access to a variety of information or that allow the public to transact business with governments online. Our software solutions and services are generally grouped in nine major areas:provided through seven business units, which focus on the following products:

Each of our core software systemssolutions consists of several fully integrated applications. For clients who acquire software for use on premises, we generally license our systemssolutions under standard perpetual license agreements that provide the client with a fully paid, nonexclusive, nontransferable right to use the software. In some of the product areas, such as financial management and education and property appraisal and tax, we offer multiple solutions designed to meet the needs of different sized governments.

We also offer SaaS arrangements for clients who do not wish to maintain, update and operate these systems or to make up-front capital expenditures to implement these advanced technologies. For these clients, the software and client data are hosted at our data centers or at third-party locations, and clients typically sign multi-year contracts for these subscription-based services.

A description of our suites of products and services follows:

Our financial management and education solutions are enterprise resource planning systems for the public sector, which integrate information across all facets of a client organization. Our financial management solutions include modular fund accounting systems that can be tailored to meet the needs of virtually any government agency or not-for-profit entity. Our financial management systems include modules for general ledger, budget preparation, fixed assets, requisitions, purchase orders, bid management, accounts payable, contract management, accounts receivable, investment management, inventory control, project and grant accounting, work orders, job costing, GASB reporting, payroll and human resources. All of our financial management systems are intended to conform to government auditing and financial reporting requirements and generally accepted accounting principles.

We sell utility billing systems that support the billing and collection of metered and non-metered services, along with multiple billing cycles. Our Web-enabled utility billing solutions allow clients to access information online such as average consumption and transaction history. In addition, our systems can accept secured Internet payments via credit cards and checks.

We also offer specialized products that automate numerous city and county functions, including municipal courts, parking tickets, equipment and project costing, animal licenses, business licenses, permits and inspections, code enforcement, citizen complaint tracking, ambulance billing, fleet maintenance, and cemetery records management.

In addition to providing financial management systems to K-12 schools, we sell student information systems for K-12 schools, which manage such activities as scheduling, grades and attendance. We also offer student transportation solutions to manage school bus routing optimization, fleet management, field trips and other related functions.

Tyler’s financial management and education solutions include Web components that enhance governments’ service capabilities by facilitating online access to information for both employees and citizens and enabling online transactions.

We offer a complete, fully integrated suite of judicial solutions designed to handle complex, multi-jurisdictional county or statewide implementations as well as single county systems. Our solutions help eliminate duplicate data entry, promote more effective business procedures, and improve efficiency across the entire justice process.

Our unified court case management system is designed to automate the tracking and management of information involved in all case types, including criminal, traffic, civil, family, probate and juvenile courts. It also tracks the status of cases, processes fines and fees and generates the specialized judgment and sentencing documents, notices and forms required in the court process. Documents received by the court can be scanned into the electronic case file and easily retrieved for viewing. Documents generated by the court can be electronically signed and automatically attached to the electronic case file. Additional modules automate the management of court calendars, coordinate judges' schedules and generate court dockets. Our targeted courtroom technologies allow courts to rapidly review calendars, cases and view documents in the courtroom. Courts may also take advantage of our related jury management system. We also offer a solution for online dispute resolution that automates the flow and resolution of common and historically time-consuming disputes including debt, landlord, tenant, small claims, child custody and other case types.

Our court and law enforcement systems allow the public to access, via the Internet, a variety of information, including non-confidential criminal and civil court records, jail booking and release information, bond and bondsmen information, and court calendars and dockets. In addition, our systems allow cities and counties to accept payments for traffic and parking tickets over the Internet, with a seamless and automatic interface to back-office justice and financial systems.

Our prosecutor system enables state attorney offices to track and manage criminal cases, including detailed victim information and private case notes. Investigative reports and charging instrument documents can be generated and stored for later viewing. Prosecutors can schedule and record the outcome of grand jury hearings. When integrated with the court system, prosecutors can view the electronic case file and related documents, as well as manage witness lists and subpoenas needed for court hearings.

Our supervision system allows pre-trial and probation offices to manage offender caseloads. Supervision officers can track contact schedules, risk/needs assessments and reassessments, detailed drug test results, employment histories, compliance with conditions and payments of fees and restitution. Documents and forms, like pre-sentence investigations or revocation orders, can be generated and stored for easy viewing. When integrated with the jail and court systems, supervision officers obtain easy access and quick notification of offenders that have court hearings scheduled, are arrested locally, and have new warrants issued.

We also offer a court case management solution that automates and tracks all aspects of municipal courts and offices. It is a fully integrated, graphical application that provides effective case management, document processing and cash/bond management. This system complies with all state reporting and conviction reports and includes electronic reporting and also integrates with certain of our financial management solutions and public safety solutions.

Also our product solutions provide a suite of financial and communications applications ranging from deposit technologies for commissary, ordering, and warehouse technology to a host of informational, electronic communications, security, accounting, and financial trust management components for correctional facilities.

Our public safety software is a fully unified and comprehensive solution for law enforcement, fire and EMS, including 911 / computer aided dispatch (“CAD”), records management, mobile computing, corrections management, Web-based information sharing and decision support. The modules are fully integrated, utilizing a common database and providing full functionality between modules, reducing data entry. The software provides fast, efficient dispatching, and quick access to records, reports and actionable information from an agency’s database.

Our 911 / CAD solutions provide real-time, critical response dispatch functions in either single- or multi-jurisdictional environments. When integrated with our records management software, a vital link exists between dispatch and the most comprehensive records database available. Within seconds, the dispatch operator and the officer in the field can access critical information, such as prior incidents and outstanding warrants, increasing officer knowledge and safety. The solutions offer strong geographic information systems integration to help dispatchers quickly locate and send the best response during an emergency. Our 911 / CAD solutions dramatically improve performance, response time and unit safety.

Our records management solutions for law enforcement and fire track statistical, operational, investigative and management data for inquiry and reporting. The systems create an efficient case processing workflow and help solve crimes with an accessible database that maintains central files on people, places, property, vehicles and criminal activity. Our public safety records management solutions enable easy access to information and simplify reporting.

Our mobile computing solutions for law enforcement and fire provide instant access to local, state, regional and federal databases via mobile devices. Officers and firefighters can experience the benefits of obtaining critical, real-time information in the field, while saving time by preparing reports directly in their vehicles.

Our jail management systems document and manage information that meets the requirements of a modern jail facility. This includes the booking and housing of persons in custody, supervising defendants on a pre-trial release, maintaining offenders sentenced to local incarceration and billing other agencies for housing inmates. Searching, reporting and tracking features are integrated, allowing reliable, up-to-date access to current arrest and incarceration data, including digital mug shots. Our systems also provide warrant checks for visitors or book-ins, inmate classification and risk assessment, commissary, property and medical processing, automation of statistics, and state and federal reporting.

Our civil processing solutions manage civil process needs from document receipt through service, payment process and final closeout. We also have a mobile electronic citation solution through which law enforcement officers can easily enter citation information in a mobile device, which is automatically uploaded into the court or public safety records management systems, rather than hand-writing citations that must be re-entered into the systems.

We provide systems and software that automate the appraisal and assessment of real and personal property, including record keeping, mass appraisal, inquiry and protest tracking, appraisal and tax roll generation, tax statement processing, and electronic state-level reporting. These systems are image and video-enabled to facilitate the storage of and access to the many property-related documents and for the online storage of digital photographs of properties for use in defending values in protest situations. Other related tax applications are available for agencies that bill and collect taxes, including cities, counties, school tax offices, and special taxing and collection agencies. These systems support billing, collections, lock box operations, mortgage company electronic payments, and various reporting requirements.

Our planning, regulatory and maintenance software solutions are designed for public sector agencies such as community development, planning, building, code enforcement, tax and revenues, public works, transportation, land control, environmental, fire safety, storm water management, regulatory controls and engineering. These solutions help public sector agencies better manage their day-to-day business functions while streamlining and automating the many aspects of their land management, permitting and planning systems. Our mobile solutions extend automation to the field and Web access brings online services to citizens 24 hours a day, 365 days a year.

We also offer a number of specialized software applications designed to help local governments enhance and automate operations involving records and document management. These systems record, scan and index information for the many documents maintained by local governments, such as deeds, mortgages, liens, UCC financing statements and vital records (birth, death and marriage certificates). These applications include fully integrated imaging systems with batch and scan processing capabilities and fully integrated receipting and cashiering systems, as well as Web-enabled public access.

Our content management solutions allow state and local governments and school districts to capture, deliver, manage and archive electronic information. These solutions streamline the flow of digital information throughout the organization to increase efficiency by transforming paper forms and documents into electronic images that drive key business processes.

Our data and insights solutions make existing government data discoverable, usable, and actionable for government workers and the people they serve. The data and insights solution includes a data-as-a-service platform and cloud applications for open data and citizen engagement, exclusively for city, county, state, and federal government organizations. Our data and insights solutions allow government to analyze, visualize, and securely share data across multiple departments and programs. These solutions deliver data-driven innovation and cost-savings by bringing together disparate systems and leveraging the cloud to dramatically enhance the effectiveness of government programs, to improve quality of life for residents, to positively impact local economies, and to achieve excellence in government operations.

We offer a low-code application development platform solution for case management and business process management. Whether based on premises or in the cloud, its Data-First™ approach allows the application to be implemented immediately and configured continuously, enabling clients to get to work quickly while keeping costs low. Our low code application platform allows government agencies the ability to track, collaborate, and report on the data that drives activities forward.

On April 21, 2021, we acquired NIC, Inc. (“NIC”). NIC deliversWe deliver user-friendly digital services that make it easier and more efficient for citizens and businesses to interact with government providing valuable conveniences like applying for unemployment insurance, submitting business filings, renewing licenses, accessing information and making secure payments without visiting a government office. NICOur digital government services unit designs, builds, and operates digital government services on an enterprise-wide basis on behalf of state and local governments desiring to provide access to government information and to complete secure government-based transactions through multiple digital channels. These digital government services consist of websites and applications NIC has built that allow consumers, such as businesses and citizens, to access government information, complete transactions and make electronic payments. NICWe also providesprovide payment processing services, software development and digital government services, other than those services provided under state enterprise contracts, to federal agencies as well as state and local governments.

We derive our revenues from five primary sources:

Many of our software arrangements involve “off-the-shelf” software. We recognize the revenue allocable to “off-the-shelf” software licenses and specified upgrades at a point in time when control of the software license transfers to the customer, unless the software is not considered distinct. We consider "off-the-shelf" software to be distinct when it can be added to an arrangement with minor changes in the underlying code, it can be used by the customer for the customer’s purpose upon installation, and remaining services such as training are not considered highly interdependent or interrelated to the product's functionality.

For arrangements that involve significant production, modification or customization of the software, or where softwareprofessional services are otherwise not considered distinct, we recognize revenue over time by measuring progress-to-completion. We measure progress-to-completion primarily using labor hours incurred as it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. These arrangements are often implemented over an extended period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent.

Software license fees are billed in accordance with the contract terms. Typically, a majority of the fee is due when access to the software license is made available to the customer and the remainder of the fee due over a passage of time stipulated by the contract. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.

We recognize royalty revenue when the sale occurs under the terms of our third-party royalty arrangements. Currently, our third-party royalties are recognized on an estimated basis and adjusted if needed, when we receive notice of amounts we are entitled to receive. We typically receive notice of royalty revenuesrevenue we are entitled to and billed on a quarterly basis in the quarter immediately following the royalty reporting period and adjustments have not been significant.

We are the nation’s largest provider of property appraisal outsourcing services for local government taxing authorities. These services include:

Local government taxing authorities normally reappraise properties from time to time to update values for tax assessment purposes and to maintain equity in the taxing process. In some jurisdictions, law mandates reassessment cycles; in others, they are discretionary. While some taxing jurisdictions perform reappraisals in-house, many local governments outsource this function because of its cyclical nature and because of the specialized knowledge and expertise requirements associated with it. Our appraisal services business unit has operated in this business since 1938.

In some instances, we also provide property tax and / or appraisal software products in connection with appraisal outsourcing projects, while other clients may only engage us to provide appraisal services. Appraisal outsourcing services are somewhat seasonal in nature to the extent that winter weather conditions reduce the productivity of data collection activities in connection with those projects.

STRATEGY

Our objective is to grow our revenuerevenues and earnings organically, supplemented by focused strategic acquisitions. The key components of our business strategy are to:

SALES, MARKETING AND CLIENTS

We market our products and services primarily through direct sales and marketing personnel located throughout the United States. Other in-house sales staff focus on add-on sales, professional services and support. For certain products we also utilize a partner network for both sales and professional services, primarily in the state and federal markets.

Sales of new systems are typically generated from referrals from other government offices or departments within a county or municipality, referrals from other local governments, relationships established between sales representatives and county or local officials, contacts at trade shows, direct mailings, and direct contact from prospects already familiar with us. We are active in numerous national, state, county, and local government associations and participate in annual meetings, trade shows, and educational events.

Clients consist primarily of federal, state, county and municipal agencies, school districts and other local government offices. In counties, clients include the auditor, treasurer, tax assessor/collector, county clerk, district clerk, county and district court judges, probation officers, sheriff, and county appraiser. At municipal government sites, clients include directors from various departments, including administration, finance, utilities, public works, code enforcement, personnel, purchasing, taxation, municipal court and police. At the state and federal levels, clients include Chief Information Officers and agency heads. Contracts for software products and services are generally implemented over periods of three months to one year, although some complex implementations may span multiple years, with annually renewing maintenance and support update agreements thereafter. Although either the client or we can terminate these agreements, historically almost all support and maintenance agreements are automatically renewed annually. During 2021,2022, approximately 30%25% of our revenue was attributable to ongoing support and maintenance agreements.

COMPETITION

We compete with numerous local, regional, and national firms that provide or offer some or many of the same solutions and services that we provide. Many of these competitors are smaller companies that may offer less expensive solutions than ours. Many of these firms operate within a specific geographic area and / or in a narrow product or service niche. We also compete with national firms, some of which have greater financial and technical resources than we do, including Oracle Corporation, Infor, SAP AG, Workday, Inc., CentralSquare Technologies, Thomson Reuters Corporation, Motorola Solutions, Inc., Axon Enterprise, Inc., and Constellation Software, Inc. In addition, we sometimes compete with consulting and systems integration firms, which develop custom systems, primarily for larger governments. We also occasionally compete with central internal information service departments of governments, which requires us to persuade the end-user department to discontinue service by its own personnel and outsource the service to us.

We compete on a variety of factors, including price, service, name recognition, reputation, technological capabilities, and the ability to modify existing products and services to accommodate the individual requirements of the client. Our ability to offer an integrated system of applications for several offices or departments is often a competitive advantage. Governmental units often are required to seek competitive proposals through a request for proposal process and some prospective clients use consultants to assist them with the proposal and vendor selection process.

SUPPLIERS

Substantially all of the computers, peripherals, printers, scanners, operating system software, office automation software, and other equipment necessary for the implementation and provision of our software systems and services are presently available from several third-party sources. Hardware is purchased on original equipment manufacturer or distributor terms at discounts from retail. We have not experienced any significant supply problems.

BACKLOG

At December 31, 2021,2022, our revenue backlog was approximately $1.80$1.89 billion, compared to $1.59$1.80 billion at December 31, 2020.2021. The backlog generally represents signed contracts under which the revenue has not been recognized. Approximately $840$886 million, or 47%, of the backlog is expected to be recognized during 2022.2023.

INTELLECTUAL PROPERTY, PROPRIETARY RIGHTS, AND LICENSES

We regard certain features of our internal operations, software, and documentation as confidential and proprietary and rely on a combination of contractual restrictions, trade secret laws and other measures to protect our proprietary intellectual property. We generally do not rely on patents. We believe that, due to the rapid rate of technological change in the computer software industry, trade secrets and copyright protection are less significant than factors such as knowledge, ability and experience of our employees, frequent product enhancements, and timeliness and quality of support services. We typically license our software products under non-exclusive license agreements, which are generally non-transferable and have a perpetual term.

Our experienced, collaborative team is one of the most significant contributors to our success in empowering the public sector to create smarter, safer, and stronger communities. Our effectiveness in attracting and developing talented team members, many of whom spend the majority of their careers at Tyler serving our public sector clients, demonstrates our commitment to providing a welcoming and safe workplace, with a culture, benefits, and opportunities for our team members to continually grow and develop their careers within Tyler.

Our team continues to work collaboratively with and for our clients and partners across multiple work arrangements: fully office-based, fully remote and a blended approach of office-based and remote work, each week which we refer to as flex-work.Regardless of where team members work, we do so together to develop for, sell to, implement and support our public sector clients.

We are committed to providing Tyler team members with career growth opportunities and the training and resources necessary to continually strengthen their skills. Our talent assessment and development programs provide managers and employees with the resources needed to achieve career goals, build management skills and lead their teams.

For example, in 2021:2022:

Our Human Resources team is tasked with leading and supporting our organization in managing employment-related matters, including recruiting and hiring, onboarding and training, compensation planning, talent management and development. Our executive team is responsible for periodically reviewing team member programs and initiatives, including healthcare and other benefits, as well as our management development and succession planning practices and our Diversity, Equity and Inclusion (“DEI”) efforts. Management periodically reports to the Board and its committees human capital measures and results that guide how we attract, retain and develop a workforce to enable our business strategies.

We believe that a diverse workforce is critical to our success, and we continue to monitor and improve the application of our hiring, retention, compensation and advancement processes for women and underrepresented populations across our workforce, including our team members of color, veterans and members of our LGBTQ community. Our Women’s Leadership Network, Veteran’s Employee Resource group (ERG),networks of support, made up of local diversity, equity, and local office diversity councils, among other programs,inclusion committees and employee resources groups, serve to enhance our inclusive and diverse culture.

INTERNET WEBSITE AND AVAILABILITY OF PUBLIC FILINGS

We file annual, quarterly, current and other reports, proxy statements and other information with the Securities and Exchange Commission, or SEC, pursuant to the Securities Exchange Act. You may read and copy any materials we file with the SEC at the SEC’s Public Reference Room by calling the SEC at 1-800-732-0330. The SEC maintains an Internet site that contains reports, proxy and other information statements, and other information regarding issuers, including us, that file electronically with the SEC. The address of this site is http://www.sec.gov.

We also maintain a website at www.tylertech.com. We make available free of charge through this site our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Forms 4 and 5, Current Reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to the SEC. In addition, copies of our annual report will be made available, free of charge, upon written request.

Our “Code of Business Conduct and Ethics” is also available on our website. We intend to satisfy the disclosure requirements regarding amendments to, or waivers from, a provision of our Code of Business Conduct and Ethics by posting such information on our website.

An investment in our common stock involves a high degree of risk. Investors evaluating our company should carefully consider the factors described below and all other information contained in this Annual Report. Any of the following factors could materially harm our business, operating results, and financial condition. Additional factors and uncertainties not currently known to us or that we currently consider immaterial could also harm our business, operating results, and financial condition. This section should be read in conjunction with the Financial Statements and related Notes and Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this Annual Report. We may make forward-looking statements from time to time, both written and oral. We undertake no obligation to revise or publicly release the results of any revisions to these forward-looking statements. Our actual results may differ materially from those projected in any such forward-looking statements due to a number of factors, including those set forth below and elsewhere in this Annual Report.

Threats to IT security can take a variety of forms. Individuals and groups of hackers, and sophisticated organizations including state-sponsored organizations, may take steps that pose threats to our clients and our IT. They may, for example, develop and deploy malicious software to attack our products and services and/or gain access to our networks and data centers or act in a coordinated manner to launch distributed denial of service or other coordinated attacks. Cyber threats are constantly evolving, thereby increasing the difficulty of detecting and successfully defending against them. Cyber threats can have cascading impacts that unfold with increasing speed across our internal networks and systems and those of our partners and clients. Breaches of our network or data security could disrupt the security of our internal systems and business applications, impair our ability to provide services to our

clients and protect the privacy of their data, result in product development delays, compromise confidential or technical business information harming our competitive position, result in theft or misuse of our intellectual property or other assets, require us to allocate more resources to improve technologies, or otherwise adversely affect our business. Our business policies and internal security controls may not keep pace with these evolving threats. Despite the network and application security, internal control measures, and physical security procedures we employ to safeguard our systems, we may still be vulnerable to a security breach, intrusion, or loss or theft of confidential client data, and transaction data, or proprietary company information, which may harm our business, reputation and future financial results. The lost revenue and containment, remediation, investigation, legal and other costs

In September 2020, we filed a Current Report on Form 8-K reporting a security incident (the "Incident") involving ransomware disrupting access to some of our internal IT systems and telephone systems. We promptly notified our clients of the Incident and provided timely updates to our clients through direct communications and updates to our website. There is no evidence that the environments where we host client applications were affected, and our hosting services to those clients were not interrupted. There was also no evidence of malicious activity on client networks associated with the Incident. We contained the Incident and recovered from it, resuming normal operations with our clients. We deployed supplemental remediation efforts as necessary and cooperated with law enforcement’s investigation.

Although we completed our investigation into the Incident and believe we contained and recovered from the Incident, we are subject to risk and uncertainties as a result of the Incident. There can be no assurance as to what the ongoing impact of the Incident will be, if any. We maintain cybersecurity insurance coverage in an amount that we believe is adequate.

We store and process increasingly large amounts of personally identifiable information and other confidential information of our clients. The continued occurrence of high-profile data breaches provides evidence of an external environment increasingly hostile to information security. Despite our efforts to improve security controls, it is possible our security controls over personal data, our training of employees on data security, and other practices we follow may not prevent the improper disclosure of sensitive client data that we store and manage. Disclosure of personally identifiable information and/or other sensitive client data could result in liability and harm our reputation.

In addition, we may act as subcontractor to a third-party prime contractor to secure new projects. Subcontracting arrangements where we are not the prime contractor pose unique risks to us because we may not have control over the customer relationship, and our ability to generate revenuerevenues under such subcontracts may depend on the prime contractor, its performance and relationship with the customer, and its relationship with us. We could suffer losses in the event a prime contract under which we serve as a subcontractor is terminated, whether for non-performance by the prime contractor or otherwise. Upon a termination of the prime contract, our subcontract would similarly terminate, and the resulting contract loss could have an adverse effect on our business prospects, results of operations, cash flows, and financial condition and our ability to compete for future contracts and orders.

A material portion of our business is provided through software hosting services, which are sometimes hosted from and use computing infrastructure provided by third parties, including Amazon Web Services. These hosting services depend on the uninterrupted operation of data centers and the ability to protect computer equipment and information stored in these data centers against damage that may be caused by natural disaster, fire, power loss, telecommunications or Internet failure, acts of terrorism, unauthorized intrusion, computer viruses, and other similar damaging events. If any of our data centers were to become inoperable for an extended period, we might be unable to fulfill our contractual commitments. Although we take what we believe to be reasonable precautions against such occurrences, we can give no assurance that damaging events such as these will not result in a prolonged interruption of our services, which could result in client dissatisfaction, loss of revenue,revenues, and damage to our business.

Part of our future success continues to depend on the use of the Internet as a means to access public information and perform transactions electronically, including, for example, electronic filing of court documents. This in part requires ongoing maintenance of the Internet infrastructure, especially to prevent interruptions in service, as well as additional development of that infrastructure. This requires a reliable network backbone with the necessary speed, data capacity, security, and timely development of complementary products for providing reliable Internet access and services. If this infrastructure fails to be sufficiently developed or be adequately maintained, our business would be harmed because users may not be able to access our government portals.

Our software products are complex and may contain errors or defects, especially when first introduced or when new versions or enhancements are released. Any such defects could result in a loss of revenues or delay market acceptance. Our license agreements typically contain provisions designed to limit our exposure to potential liability. However, it is possible we may not always successfully negotiate such provisions in our client contracts or the limitation of liability provisions may not be effective due to existing or future federal, state, or local laws, ordinances, or judicial decisions. Although we maintain errors and omissions and general liability insurance, and we try to structure contracts to limit liability, we cannot assure you that a successful claim could not be made or would not have a material adverse effect on our future operating results.

The market for our products is characterized by technological change, evolving industry standards in software technology, changes in client requirements, and frequent new product introductions and enhancements. The introduction of products embodying new technologies and the emergence of new industry standards can render existing products obsolete and unmarketable. As a result, our future success will depend, in part, upon our ability to enhance existing products and develop and introduce new products that keep pace with technological developments, satisfy increasingly sophisticated client requirements, and achieve market acceptance. We cannot assure you that we will successfully identify new product opportunities and develop and bring new products to market in a timely and cost-effective manner. The products, capabilities, or technologies developed by others could also render our products or technologies obsolete or noncompetitive. Our business may be adversely affected if we are unable to develop or acquire new software products or develop enhancements to existing products on a timely and cost-effective basis, or if such new products or enhancements do not achieve market acceptance.

Many of our product and service offerings incorporate proprietary information, trade secrets, know-how, and other intellectual property rights. We rely on a combination of contracts, copyrights, and trade secret laws to establish and protect our proprietary rights in our technology. We cannot be certain that we have taken all appropriate steps to deter misappropriation of our intellectual property. There has also been an apparent evolution in the legal standards and regulations courts and the U.S. patent office may apply in favorably evaluating software patent rights. We are not currently involved in any material intellectual property litigation; however, we may be a party to such litigation in the future to protect our proprietary information, trade secrets, know-how, and other intellectual property rights. We cannot assure you that third parties will not assert infringement or misappropriation claims against us with respect to current or future products. Any claims or litigation, with or without merit, could be time-consuming, costly, and a diversion to management. Any such claims and litigation could also cause product shipment delays or require us to enter into royalty or licensing arrangements. Such royalty or licensing arrangements, if required, may not be available on terms acceptable to us, if at all. Therefore, litigation to defend and enforce our intellectual property rights could have a material adverse effect on our business, regardless of the final outcome of such litigation.

It is possible that our clients may elect to not renew maintenance contracts for our software, trying instead to maintain and operate the software themselves using their perpetual license rights (excluding software applications that we provide on a hosted or cloud basis). Alternatively, clients may elect to drop maintenance on certain modules that they ultimately decide not to use. This could adversely affect our revenues and profits. Additionally, they may inadvertently allow our intellectual property or other information to fall into the hands of third parties, including our competitors, which could adversely affect our business.

We derive substantially all of our revenues from sales of software and services to state, county, and city governments, other federal or municipal agencies, and other public entities. We expect that sales to public sector clients will continue to account for substantially all of our revenues in the future. We face many risks and challenges associated with contracting with governmental entities, including:

Each of these risks is outside our control. If we fail to adequately adapt to these risks and uncertainties, our financial performance could be adversely affected.

Because an increasing portion of our revenues are recurring, the effect of COVID-19 on our results of operations may also not be fully reflected for some time. We may see some more immediate impact on our business should there be new delays in government procurement processes and uncertainty around public sector budgets, or new delays in implementations caused by travel restrictions, closed offices, or clients shifting focus to more pressing issues.

Appraisal and software implementations projects may be delayed if clients put projects on hold or slow projects by extending go-live dates. While we have the ability to deliver most of our professional services remotely, some of our professional services, including appraisal assessments, are more effective when performed on-site, and certain clients may continue to insist on on-site services in any event. In addition, our delivery of some professional services requires the availability of client personnel. There may be a negative impact on our revenues if we are unable to deliver these services. Also, we expect software licenses and subscriptions revenues to be negatively affected if there are delays in procurement processes. Some clients could request changes to payment terms, negatively impacting the timing of collections of accounts receivables in future periods. For the twelve months ended December 31, 2021, 79%2022, 80% of our total revenuerevenues and earnings are relatively predictable as a result of our subscription and maintenance revenue, which is recurring in nature; thus the effect of the COVID-19 pandemic may not be fully reflected in our results of operations and overall financial performance until future periods.

We have historically evaluated goodwill for impairment annually as of AprilOctober 1, or more frequently if impairment indicators arose. During the second quarter 2021, we voluntarily changed the date of our annual assessment of goodwill to October 1 for all reporting units. The change in testing date for goodwill impairment is a change in accounting principle, which management believes is preferable as the new date of the assessment better aligns with our annual planning process. Subsequent to our annual goodwill impairment analysis, we monitor for any events or changes in circumstances, such as significant adverse changes in business climate or operating results, changes in management’s business strategy, an inability to successfully introduce new products in the marketplace, an inability to successfully achieve internal forecasts or significant declines in our stock price, which may represent an indicator of impairment. The occurrence of any of these events, which could be caused or impacted by the COVID-19 pandemic, may require us to record future goodwill impairment charges.

A prolonged economic slowdown or recession could reduce demand for our software products and services. Governments may face financial pressures that could in turn affect our growth rate and profitability in the future. There is no assurance that government spending levels will be unaffected by declining or stagnant general economic conditions, and if budget shortfalls occur, they may negatively impact government IT spending and could adversely affect our business.

Many governmental agencies purchase products and services through an open bidding process. Generally, a governmental entity will publish an established list of requirements requesting potential vendors to propose solutions for the established requirements. To respond successfully to these requests for proposals, we must accurately estimate our cost structure for servicing a proposed contract, the time required to establish operations for the proposed client, and the likely terms of any other third-party proposals submitted. We cannot guarantee that we will win any bids in the future through the request for proposal process, or that any winning bids will ultimately result in contracts on favorable terms. Our failure to secure contracts through the open bidding process, or to secure such contracts on favorable terms, may adversely affect our revenuerevenues and gross margins.

We believe we are a leading provider of integrated solutions for the public sector. However, we face competition from a variety of software vendors that offer products and services similar to those offered by us, as well as from companies offering to develop custom software. We compete based on a number of factors, including:

Our market is highly fragmented with a large number of competitors that vary in size, product platform, and product scope. Our competitors include consulting firms, publicly held companies that focus on selected segments of the public sector market, and a significant number of smaller, privately held companies. Certain competitors have greater technical, marketing, and financial resources than we do. We cannot assure you that such competitors will not develop products or offer services that are superior to our products or services or that achieve greater market acceptance.

We also compete with internal, centralized IT departments of governmental entities, which requires us to persuade the end-user to stop the internal service and outsource to us. In addition, our clients and prospective clients could elect to provide information management services internally through new or existing departments, which could reduce the market for our services.

We could face additional competition as other established and emerging companies enter the public sector software market and new products and technologies are introduced. Increased competition could result in pricing pressure, fewer client orders, reduced gross margins, and loss of market share. Current and potential competitors may make strategic acquisitions or establish cooperative relationships among themselves or with third parties, thereby increasing the ability of their products to address the needs of our prospective clients. It is possible that new competitors or alliances may emerge and rapidly gain significant market share. We cannot assure you that we will be able to compete successfully against current and future competitors, and the failure to do so would have a material adverse effect upon our business.

Some of our contracts are structured on a fixed-price basis, which can lead to various risks, including:

If we do not adequately assess and manage these and other risks, we may be subject to cost overruns and penalties, which may harm our financial performance.

Some of our clients, primarily those for our property appraisal services, require that we secure performance bonds before they will select us as their vendor. In addition, we have in the past been required to provide letters of credit as security for the issuance of a performance bond. We cannot guarantee that we will be able to secure such performance bonds in the future on terms that are favorable to us, if at all. Our inability to obtain performance bonds on favorable terms or at all could impact our future ability to win some contract awards, particularly large property appraisal services contracts, which could negatively impact revenues. In addition, the general insurance markets may experience volatility and/or restrictive coverage trends, which may lead to future increases in our general and administrative expensesexpense and negatively impact our operating results.

As of December 31, 2021,2022, we had outstanding an aggregate principal amount of $600 million of our Convertible Senior Notes and $755$395 million under our 2021 Credit Agreement. In April 2021, we entered into the 2021 Credit Agreement with significantly increased borrowing capacity of up to $1.4 billion and on the closing of the acquisition of NIC on April 21, 2021, we borrowed initial loans in

Pursuant to their terms, holders may convert their Convertible Senior Notes at their option prior to the scheduled maturities of their Convertible Senior Notes under certain circumstances. Upon conversion of the Convertible Senior Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be obligated to make cash payments. In addition, holders of our Convertible Senior Notes will have the right to require us to repurchase their Convertible Senior Notes upon the occurrence of a fundamental change (as defined in the Indenture, dated as of March 9, 2021, between the Company and U.S. Bank National Association, as trustee (the “Trustee”) (the “Indenture”), at a repurchase price equal to 100% of the principal amount of the Convertible Senior Notes to be repurchased, plus accrued and unpaid interest, if any. Although it is our intention, and we currently expect to have the ability, to settle the Convertible Senior Notes in cash, there is a risk that we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of Convertible Senior Notes surrendered or Convertible Senior Notes being converted. In addition, our ability to make payments may be limited by law, by regulatory authority, or by agreements governing our future indebtedness. Our failure to repurchase Convertible Senior Notes at a time when the repurchase is required by the Indenture or to pay any cash payable on future conversions of the Convertible Senior Notes as required by the Indenture would constitute a default under the Indenture. A default under the Indenture or the fundamental change itself could also lead to a default under agreements governing our other existing or future indebtedness. If the repayment of other indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the other indebtedness and repurchase the Convertible Senior Notes or make cash payments upon conversions thereof.

Our ability to make scheduled payments of the principal and interest on our indebtedness when due or to make payments upon conversion or repurchase demands with respect to our Convertible Senior Notes, or to refinance our indebtedness as we may need or desire, depends on our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to satisfy our obligations under our existing indebtedness, and any future indebtedness we may incur, and to make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, refinancing, or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance existing or future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our existing or future indebtedness and have a material adverse effect on our business, results of operations, and financial condition.

The Indenture governing the Convertible Senior Notes and the 2021 Credit Agreement do, and our future indebtedness agreements may, contain covenants that may restrict our ability to finance future operations or capital needs or to engage in other business activities. Subject to customary carve-outs, thresholds and baskets, the 2021 Credit Agreement (and the Indenture by means of a cross-default) restricts, absent consent of the agent and lenders under the 2021 Credit Agreement, our ability and the ability of our restricted subsidiaries to, among other things:

In addition, the 2021 Credit Agreement (and the Indenture by means of a cross-default) contains other customary affirmative and negative covenants, and events of default. The 2021 Credit Agreement is unsecured but requires us to maintain certain financial ratios regarding our total leverage and interest coverage and other financial conditions in addition to the restrictions described above. Events beyond our control, including changes in general economic and business conditions, may result in a breach of any of these covenants and result in a default under the 2021 Credit Agreement that may, in turn, result in a default under the Indenture. If an event of default under the 2021 Credit Agreement occurs, the lenders could terminate all commitments to lend and elect to declare all amounts outstanding thereunder, together with accrued interest, to be immediately due and payable. If we were unable to pay such amounts, the lenders could proceed against the guarantees by our direct and indirect material domestic subsidiaries. Should the lenders proceed

Our borrowings under the 2021 Credit Agreement are, and are expected to continue to be, at variable rates of interest and expose Tyler to interest rate risk. If interest rates continue to increase, our debt service obligations on the variable rate indebtedness would increase even though the amount borrowed remained the same, and our net income would decrease. Revolving credit facility loans and Term A-1 Loans under the 2021 Credit Agreement bear interest at a per annum rate equal to, at our option, either (1) the administrative agent’s prime commercial lending rate (subject to certain higher rate determinations) (the “Base Rate”) plus a margin of 0.125% to 0.75% or (2) the one-, three-, six-, or, subject to approval by all lenders, twelve-month LIBOR rate plus a margin of 1.125% to 1.75%. Our Term A-2 Loans bear interest, at our option, at a per annum rate of either (1) the Base Rate plus a margin of 0.00%0% to 0.50%0.5% or (2) the one-, three-, six-, or, subject to approval by all lenders, twelve-month LIBOR rate plus a margin of 0.875% to 1.50%1.5%. The margin in each case is based upon our total net leverage ratio, as determined pursuant to the 2021 Credit Agreement. Based on the debt under the 2021 Credit Agreement, the aggregate principal outstanding balance as of December 31, 20212022 is $755.0$395.0 million, and each quarter point change in interest rates would result in a $1.9$1.0 million change in annual interest expense.

In the event the conditional conversion feature of the notes is triggered, holders of our Convertible Senior Notes will be entitled to convert the Convertible Senior Notes at any time during specified periods at their option. If one or more holders elect to convert their Convertible Senior Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Convertible Senior Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Our Convertible Senior Notes may become convertible in the future at the option of their holders under certain circumstances. If holders of our Convertible Senior Notes elect to convert their notes, we may settle our conversion obligation by delivering to them a significant number of shares of our common stock, which would cause dilution to our existing shareholders.

Our revenues and operating results are difficult to predict and may fluctuate substantially from quarter to quarter for a variety of reasons, including:

In each fiscal quarter, our expense levels, operating costs, and hiring plans are based to some extent on projections of future revenues and are relatively fixed. If our actual revenues fall below expectations, we could experience a reduction in operating results. Also, if actual revenues or earnings for any given quarter fall below expectations, it may lead to a decline in our stock price.

An important element of our corporate strategy is to continue to dedicate a significant amount of resources to research and development and related product and service opportunities both through internal investments and the acquisition of intellectual property from companies that we have acquired. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position, and research and development expensesexpense could adversely affect operating margins.

The market price of our common stock may be volatile. Examples of factors that may significantly impact our stock price include:

In addition, the stock market has from time to time experienced significant price and volume fluctuations that have particularly affected the market prices of technology company stocks and may in the future adversely affect the market price of our stock. Sometimes, securities class action litigation is filed following periods of volatility in the market price of a particular company’s securities. We cannot assure you that similar litigation will not occur in the future with respect to us. Such litigation could result in substantial costs and a diversion of management’s attention and resources, which could have a material adverse effect upon our financial performance.

From time to time, in press releases and otherwise, we may publish forecasts or other forward-looking statements regarding our results, including estimated revenues or earnings. Any forecast of our future performance reflects various assumptions. These assumptions are subject to significant uncertainties, and as a matter of course, any number of them may prove to be incorrect. Further, the achievement of any forecast depends on numerous risks and other factors (including those described in this discussion), many of which are beyond our control. As a result, we cannot be certain that our performance will be consistent with any management forecasts or that the variation from such forecasts will not be material and adverse. Current and potential stockholders are cautioned not to base their entire analysis of our business and prospects upon isolated predictions, but instead are encouraged to utilize our entire publicly available mix of historical and forward-looking information, as well as other available information regarding us, our products and services, and the software industry when evaluating our prospective results of operations.

A material portion of our historical growth has resulted from strategic acquisitions. Although our focus is on organic internal growth, we will continue to identify and pursue strategic acquisitions with suitable candidates. These transactions involve significant challenges and risks, including risks that a transaction does not advance our business strategy; that we do not achieve the expected return on our investment; that we have difficulty integrating business systems and technology; that we have difficulty retaining or integrating new employees; that the transactions distract management from our other businesses; that we acquire unforeseen liabilities; and other unanticipated events. Our future success will depend, in part, on our ability to successfully integrate future acquisitions into our operations. It may take longer than expected to realize the full benefits of these transactions, such as increased revenue, enhanced efficiencies, or increased market share, or the benefits may be ultimately less than we expected. Although we conduct due diligence reviews of potential acquisition candidates, we may not identify all material liabilities or risks related to acquisition candidates. There can be no assurance that any such strategic acquisitions will be accomplished on favorable terms or will result in profitable operations.

We continue to expand our operations by pursuing existing and potential market opportunities. This growth places significant demands on management and operational resources. In order to manage growth effectively, we must implement and improve our operational systems, procedures, and controls on a timely basis. If we fail to implement these systems, our business may be materially adversely affected.

Our continued success will depend upon the availability and performance of our key management, sales, marketing, client support, and product development personnel. The loss of key management or technical personnel could adversely affect us. We believe that our continued success will depend in large part upon our ability to attract, integrate, and retain such personnel. We have at times experienced and continue to experience challenges in recruiting qualified personnel. Competition for qualified software development, sales, and other personnel is intense, and we cannot assure you that we will be successful in attracting and retaining such personnel. In addition, competitive job markets may increase our costs relating to compensation packages due to higher salary expectations and pressures.

Changing laws, regulations, and standards relating to corporate governance, compliance, and public disclosure can create uncertainty for public companies. The costs required to comply with such evolving laws across the various states and at the federal level are difficult to predict and/or harmonize. To maintain high standards of corporate governance, compliance, and public disclosure, we intend to invest all reasonably necessary resources to comply with evolving standards. This investment may result in an unforeseen increase in general and administrative expensesexpense and a diversion of management’s time and attention from revenue-generating activities, which may harm our operating results.

We have not declared nor paid a cash dividend since we entered the business of providing software solutions and services to the public sector in 1998. We intend to retain earnings for use in the operation and expansion of our business. We do not anticipate paying any cash dividends on our common stock in the foreseeable future.

Our board of directors may issue up to 1,000,000 shares of preferred stock and may determine the price, rights, preferences, privileges, and restrictions, including voting and conversion rights, of these preferred shares. These determinations may be made without any further vote or action by our stockholders. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock may make it more difficult for a third-party to acquire a majority of our outstanding voting stock. In addition, some provisions of our Certificate of Incorporation, Bylaws, and the Delaware General Corporation Law could also delay, prevent, or make more difficult a merger, tender offer, or proxy contest involving us.

The client has not filed responsive pleadings and no material legal proceedings pending to whichother significant activity has occurred in the lawsuit. Although we believe our products and services were delivered in accordance with the terms of our contract and that we are partyentitled to payment in connection with the termination for convenience, at this time the matter remains unresolved. We are unable to estimate the probability of a favorable or unfavorable outcome with respect to whichthe dispute or estimate the amount of potential loss, if any, ofrelated to this matter.

Most of our stockholders hold their shares in street name; therefore, there are substantially more than 1,0901,065 beneficial owners of our common stock.

We did not pay any cash dividends in 20212022 or 2020.2021. Our bank credit agreement contains restrictions on the payment of cash dividends. We intend to retain earnings for use in the operation and expansion of our business and do not anticipate paying a cash dividend in the foreseeable future.

CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS

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) the ongoingcontinuing effects of the COVID-19 pandemic, including its potential effects on the economic environment, our customers and our operations, as well as any changes to federal, state or local government laws, regulations or orders in connection with the pandemic; (2) changes in the budgets or regulatory environments of our clients, primarily local and state governments, that could negatively impact information technology spending; (3) disruption to our business and harm to our competitive position resulting from cyber-attacks and security vulnerabilities; (4) our ability to protect client information from security breaches and provide uninterrupted operations of data centers; (5) our ability to achieve growth or operational synergies through the integration of acquired businesses, while avoiding unanticipated costs and disruptions to existing operations; (6) material portions of our business require the Internetinternet infrastructure to be adequately maintained; (7) our ability to achieve our financial forecasts due to various factors, including project delays by our clients, reductions in transaction size, fewer transactions, delays in delivery of new products or releases or a decline in our renewal rates for service agreements; (8) general economic, political and market conditions;conditions, including inflation and changes in interest rates; (9) technological and market risks associated with the development of new products or services or of new versions of existing or acquired products or services; (10) competition in the industry in which we conduct business and the impact of competition on pricing, client retention and pressure for new products or services; (11) 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 (12) 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 Item 1A, “Risk Factors”. We expressly disclaim any obligation to publicly update or revise our forward-looking statements.

OVERVIEW

General

As of January 1, 2021, certain administrative costs related to information technology,2022, the appraisal and tax software solutions, land and vital records management software solutions, and property appraisal service business unit, which werewas previously reported in the ES and Appraisal & Tax ("A&T segments, were&T") reportable segment, was moved to the CorporateES reportable segment. The digital government and payments solutions, which was previously reported in the NIC reportable segment, and development platform solutions moved to the PT reportable segment to reflect changes in the way in which management makes operating decisions, allocates resources, and manages the growth and profitability of the Company. As a result of the changes in our reportable segments, the former A&T and NIC reportable segments are no longer considered separate segments. Prior yearperiod amounts for allthe ES and PT reportable segments have been adjusted to reflect the segment change. See Note 15,17, "Segment and Related Information," in the notes to the consolidated financial statements for additional information.

On September 9, 2021, we acquired all the equity interest of Ultimate Information Systems, Inc. (dba Arx). Arx is a cloud-based platform which creates accessible technology to enable a modern-day police force that is fully transparent, accountable, and a trusted resource to the community it serves. The total purchase price, net of cash acquired, was approximately $12.8 million, of which $12.4 million was paid in cash and approximately $0.5 million was accrued for indemnity holdbacks, subject to certain post-closing adjustments.million.

On September 1, 2021, we acquired VendEngine, Inc (VendEngine) as contemplated by the Agreement and Plan of Merger dated June 3, 2021. As result of the merger, VendEngine became a direct subsidiary of the Company. VendEngine is, a cloud-based software provider focused on financial technology for the corrections market. The total purchase price, net of cash acquired of $1.7 million, was approximately $83.8$83.6 million, consisting of $80.2$81.6 million paid in cash, and approximately $5.4$3.8 million related to indemnity holdbacks, subject to certain post-closing adjustments.holdbacks.

On April 21, 2021, (“the Closing Date”), we acquired NIC, as contemplated by the Agreement and Plan of Merger dated February 9, 2021. As result of the merger, NIC became a direct subsidiary of the Company and NIC’s subsidiaries became indirect subsidiaries. NIC is a leading digital government solutions and payment company that primarily serves federal and state government agencies. The total purchase price, net of cash acquired of $331.8 million, was approximately $2.0 billion, consisting of cash paid of $2.3 billion and $1.9 million of purchase consideration related to the conversion of unvested restricted stock awards, subject to post-closing adjustments.awards.

On March 31, 2021, we completed two acquisitions, Glass Arc, Inc. (dba ReadySub) and DataSpec, Inc. (DataSpec), for the combined purchase price of $12.1 million.

Our backlog atThe majority of our revenues are comprised of revenues from subscriptions and maintenance, which we consider to be recurring revenues. Annualized recurring revenues ("ARR") is calculated based on quarter-to-date end total recurring revenues multiplied by four. ARR was $1.50 billion and $1.39 billion as of December 31, 2022, and 2021, was $1.80 billion, a 12.6%respectively. ARR increased 8% compared to the prior period, due to an increase in subscriptions revenue due to an ongoing shift toward SaaS arrangements.

For the twelve months ended December 31, 2022, total revenues include COVID-related subscriptions revenue of $10.8 million from last year.NIC’s Tour Health offering and professional services revenue of $40.2 million from pandemic unemployment and Virginia rent relief offerings. These programs all ended in 2022 and we do not expect to generate COVID-related subscriptions revenue and professional services revenue in future periods.

We monitor and analyze several key performance indicators in order to manage our business and evaluate our financial and operating performance. These indicators include the following:

The local government software market continues to be active with sales activity trending at or near pre-pandemic levels in most sectors of our business, and our backlog at December 31, 20212022 reached $1.80$1.89 billion, a 12.6%5% increase from the prior year.period. We expect to continue to achieve solid growth in revenuerevenues and earnings. With our strong financial position and cash flow, we plan to continue to make significant investments in product development and accelerating our move to the cloud to better position us to continue to expand our addressable market and strengthen our competitive position over the long term. The expenses associated with the cloud transition are expected to pressure operating margins in 20222023 and 2023.2024.

Our discussion and analysis of financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities at the date of the financial statements, the reported amounts of revenues, cost of revenues and expenses during the reporting period, and related disclosure of contingencies. The Notes to the Financial Statements included as part of this Annual Report describe our significant accounting policies used in the preparation of the financial statements. Significant items subject to such estimates and assumptions include the application of the progress toward completion methods of revenue recognition, estimated standalone selling price ("SSP") for distinct performance obligations, the carryingfair value amount and estimated useful lives of intangible assets, determination of share-based compensation expense and valuation allowance for receivables.losses and sales adjustments. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe the following critical accounting policies require significant judgments and estimates used in the preparation of our financial statements.

Most of ourOur software arrangements with customers contain multiple performance obligations that range from software licenses and SaaS arrangements, installation, training, and consulting to software modification and customization to meet specific customer needs (services), hosting, and PCS. For these contracts, we account for individual performance obligations separately when they are distinct. We evaluate whether separate performance obligations can be distinct or should be accounted for as one performance obligation. Arrangements that include softwareprofessional services, such as training or installation, are evaluated to determine whether the customer can benefit from the services either on their own or together with other resources readily available to the customer and whether the services are separately identifiable from other promises in the contract. Many of our software arrangements involve “off-the-shelf” software. We recognize the revenue allocable to "off-the-shelf" software licenses and specified upgrades at a point in time when control of the software license transfers to the customer, unless the software is not considered distinct. We consider off-the-shelf software to be distinct when it can be added to an arrangement with minor changes in the underlying code, it can be used by the customer for the customer’s purpose upon installation, and remaining services such as training are not considered highly interdependent or highly interrelated to the product's functionality.

For arrangements that involve significant production, modification or customization of the software, or where softwareprofessional services are otherwise not considered distinct, we recognize revenue over time by measuring progress-to-completion. We measure progress-to-completion primarily using labor hours incurred as it best depicts the transfer of control to the customer which occurs as we incur costs on our contracts. These arrangements are often implemented over an extended period and occasionally require us to revise total cost estimates. Amounts recognized in revenue are calculated using the progress-to-completion measurement after giving effect to any changes in our cost estimates. Changes to total estimated contract costs, if any, are recorded in the period they are determined. Estimated losses on uncompleted contracts are recorded in the period in which we first determine that a loss is apparent. When softwareprofessional services are distinct, the fee allocable to the service element is recognized over the time we perform the services and is billed on a time and material or milestones basis.

Subscription-based services consist of revenues derived from SaaS arrangements, which primarily utilize the Tyler private cloud, transaction and payment processing, electronic filing transactions, and digital government services. Revenue from subscription-based services is generally recognized over time on a ratable basis over the contract term, beginning on the date that our service is made available to the customer. For SaaS arrangements, we evaluate whether the customer has the contractual right to take possession of our software at any time during the hosting period without significant penalty and whether the customer can feasibly maintain the software on the customer’s hardware or enter into another arrangement with a third-party to host the software. We allocate contract value to each performance obligation of the arrangement that qualifies for treatment as a distinct element based on estimated SSP. We recognize SaaS arrangements ratably over the terms of the arrangements, which range from one to ten years, but are typically for periods of three to five years. For softwareprofessional services associated with certain SaaS arrangements, we have concluded that the services are not distinct, and we recognize the revenue ratably over the remaining contractual period once we have provided the customer access to the software. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.

For transaction and payments revenue and e-filing transaction fees, we have the right to charge the customer an amount that directly corresponds with the value to the customer of our performance to date. Therefore, we recognize revenue for these services over time based on the amount billable to the customer in accordance with the 'as invoiced' practical expedient in ASC 606-10-55-18. In some cases, we are paid on a fixed fee basis and recognize the revenue ratably over the contractual period. Typically, the structure of our arrangements does not give rise to variable consideration. However, in those instances whereby variable consideration exists, we include in our estimates, additional revenue for variable consideration when we believe we have an enforceable right, the amount can be estimated reliably and its realization is probable.

In connection with certain of our contracts, we have recorded retentions receivable or unbilled receivables consisting of costs and estimated profit in excess of billings as of the balance sheet date. Many of the contracts which give rise to unbilled receivables at a given balance sheet date are subject to billings in the subsequent accounting period. We review unbilled receivables and related contract provisions to ensure we are justified in recognizing revenue prior to billing the customer and that we have objective evidence which allows us to recognize such revenue. In addition, we have a sizable amount of deferred revenue, which represents billings in excess of revenue earned. The majority of this liability consists of subscriptions and maintenance billings for which payments are made in advance and the revenue is ratably earned over the subscription or maintenance billing period, generally one year. We also have deferred revenue for those contracts in which we receive a deposit and the conditions in which to record revenue for the service or product have not been met. On a periodic basis, we review by customer the detail components of our deferred revenue to ensure our accounting remains appropriate.

For tangible and identifiable intangible assets acquired in a business combination, management estimates the fair value of assets acquired and liabilities assumed based on quoted market prices, the carrying value of the acquired assets and widely accepted valuation techniques, including discounted cash flows and market multiple analyses. The assumptions made in performing these valuations include, but are not limited to, discount rates, future revenues and operating costs, projections of capital costs, and other assumptions believed to be consistent with those used by principal market participants.

Due to the specialized nature of these calculations, we engage third-party specialists to assist management in evaluating our assumptions as well as appropriately measuring the fair value of assets acquired and liabilities assumed. We adjust the preliminary purchase price allocation, as necessary, up to one year after the acquisition closing date as we obtain new information about facts and circumstances that existed as of the closing date. If actual results are materially different than the assumptions we used to determine fair value of the assets acquired and liabilities assumed through a business combination as well as the estimated useful lives of the acquired intangible assets, it is possible that adjustments to the carrying values of such assets and liabilities will have a material impact on our financial position and results of operations.

We assess goodwill for impairment annually, or more frequently whenever events or changes in circumstances indicate its carrying value may not be recoverable. We begin with the qualitative assessment of whether it is more likely than not that a reporting unit's fair value is less than its carrying value before applying the quantitative assessment described below. When testing goodwill for impairment quantitatively, we first compare the fair value of each reporting unit with its carrying amount. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized. The fair values calculated in our impairment tests are determined using discounted cash flow models involving several assumptions (Level 3 inputs). The assumptions that are used are based upon what we believe a hypothetical marketplace participant would use in estimating fair value. We base our fair value estimates on assumptions we believe to be reasonable but that are unpredictable and inherently uncertain. We evaluate the reasonableness of the fair value calculations of our reporting units by comparing the total of the fair value of all of our reporting units to our total market capitalization.

Determining the fair value of our reporting units involves the use of significant estimates and assumptions and considerable management judgment. We base our fair value estimates on assumptions we believe to be reasonable at the time, but such assumptions are subject to inherent uncertainty. Changes in market conditions or other factors outside of our control, such as the COVID-19 pandemic, could cause us to change key assumptions and our judgment about a reporting unit’s prospects. Similarly, in a specific period, a reporting unit could significantly underperform relative to its historical or projected future operating results. Either situation could result in a meaningfully different estimate of the fair value of our reporting units, and a consequent future impairment charge.

All intangible assets (other than goodwill) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of other intangible assets is measured by comparison of the carrying amount to estimated undiscounted future cash flows. The assessment of recoverability or of the estimated useful life for amortization purposes will be affected if the timing or the amount of estimated future operating cash flows is not achieved. Such indicators may include, among others: a significant decline in expected future cash flows; a sustained, significant decline in stock price and market capitalization; a significant adverse change in legal factors or in the business climate; unanticipated competition; and reductions in growth rates. In addition, products, capabilities, or technologies developed by others may render our software products obsolete or non-competitive. Any adverse change in these factors could have a significant impact on the recoverability of goodwill or other intangible assets. During 2021,2022, we did not identify any triggering events that would indicate that the carrying amount of our intangible assets may not be recoverable.

There were no new not yet adopted accounting pronouncements currently issued that would affect the Company or are expected to differ from such estimates. Changes in estimated forfeitures are recognized in the periodhave a material impact on its consolidated financial position or results of change and will also impact the amount of expense to be recognizedoperations in future periods. Forfeiture rate assumptions are derived from historical data.

The following table sets forth a comparison of our subscriptions revenue for the years ended December 31:31 ($ in thousands):

Subscription-basedSubscriptions revenue increased 124%grew 29% compared to 2020,2021, primarily due to the inclusion of NIC’stransaction-based revenues from NIC including Rapid and US eDirect from the daterespective dates of acquisition. Excluding the incremental impact of revenue from 2021recent acquisitions, of $351.7 million, subscriptions revenue increased 23.4%6%. New SaaS clients as well as existing clients who converted to our SaaS model provided the majority of the subscriptionsubscriptions revenue increase. In 2021,2022, we added 533609 new SaaS clients and 239336 existing clients elected to convert to our SaaS model. Also,Our mix of new software contracts in 2022 was approximately 23% perpetual software license arrangements and approximately 77% subscription-based arrangements compared to total new client mix in 2021 of approximately 33% perpetual software license arrangements and approximately 67% subscription-based arrangements.

SoftwareProfessional services revenue primarily consists of professional services billed in connection with implementing our software, converting client data, training client personnel, custom development activities and consulting. New clients who purchase our proprietary software licenses or subscriptions generally also contract with us to provide for the related softwareprofessional services. Existing clients also periodically purchase additional training, consulting and minor programming services.

G&A expense increaseddecreased approximately 50%2% compared to the prior year period, primarily due to the inclusion NIC’s SG&A expenses. Excluding the impact of SG&A expense from 2021 acquisitions of $49.1 million, SG&A increased 31.6% compared to prior year periods.period. The increasedecrease in SGG&A is primarily attributed to lower transaction costs related to recent acquisitions higher stockand lower share-based compensation expense, higher bonus and commission expense due to improved operating results and other administrative expenses compared to prior periods. In 2021, SGexpense. G&A includes $23.5$2.0 million of transaction expenses related to acquisitions completed in 2021. We also incurred $1.62022 compared to $23.5 million of transaction expense related to a separation agreement with NIC's former Chief Executive Officer.acquisitions completed in 2021. During 2021,2022, stock compensation expense rose $31.8declined $5.5 million compared to prior periods, primarily2021, generally due to an increase in share-based awards issued in connection with our stock compensation plan coupled with the highera lower fair value of each share-based award due toresulting from the increasedecline in our stock price. SGThe decreases are offset by inclusion of G&A expense from acquisitions of $21.5 million, higher bonus expense due to improved operating results, increases in amortization of software development for internal use, increases in travel-related expenses and other administrative costs, and higher personnel costs from increased employee headcount. In 2022, G&A expense also included $3.2$2.8 million related to an accrual for litigation.

Research and development expense consists primarily of salaries, employee benefits and related overhead costs associated with new product development. The following table sets forth a comparison of our research and development expense for the years ended December 31:31 ($ in thousands):

Research and development expense consists mainly of costs associated with development of new products and technologies from which we do not currently generate significant revenue.

Research and development expense as a percent of total revenue was 5.7% in 2022 compared to 5.9% in 2021. Research and development expense increased 6%13% in 20212022 compared to the prior year period, mainly due to a number of new Tyler product development initiatives across our product suites, including increased investments in research and development at recently acquired businesses. To support these initiatives, our research and development staff grew by 107 since December 31, 2020.

AcquisitionOther intangibles are comprised of the excess of the purchase price over the fair value of net tangible assets acquired that isare allocated to acquired software leases and customer andrelated, trade name, and leases acquired intangibles. The remaining excess purchase price is allocated to goodwill that is not subject to amortization. Amortization expense related to acquired software is included with cost of revenues while amortization expense of customer and trade name intangibles is recorded as operating expense. The estimated useful lives of both customer and trade nameother intangibles range from fiveone to 25 years.
