Biggest changeThese risks are discussed more fully in the section titled “Risk Factors.” Material risks that may affect our business, financial condition, results of operations, and trading price of our Class A common stock include, but are not necessarily limited to, the following: Our recent growth may not be indicative of our future growth and, if we continue to grow, we may not be able to manage our growth effectively. If we are unable to sustain our revenue growth rate, we may not achieve or maintain profitability in the future. We may not be able to scale our business quickly enough to meet our customers’ growing needs, and if we are not able to grow efficiently, our operating results could be harmed. We are dependent on a single product, and the lack of continued market acceptance of our platform could cause our operating results to suffer. We currently face significant competition. If our security measures are actually or perceived to have been breached, or if unauthorized access to our platform or customer data occurs, our platform may be perceived as not being secure, and customers may reduce the use of or stop using our platform, and we may incur significant liabilities. We derive a material portion of our revenue from a limited number of customers, and the loss of one or more of these customers could materially and adversely impact our business, results of operations, and financial condition. We have experienced losses in the past, and we may not achieve or sustain profitability in the future. AI is a disruptive set of technologies that may affect the markets for our software dramatically and in unpredictable ways. We rely on the performance of highly skilled personnel, including senior management and our engineering, professional services, sales, and technology professionals, and if we are unable to retain or motivate key personnel or hire, retain, and motivate qualified personnel, our business would be harmed. If we do not continue to innovate and provide a platform that is useful to our customers, we may not remain competitive, and our revenue and operating results could suffer. We are substantially dependent upon customer renewals, the addition of new customers, and the continued growth of our subscriptions revenue. Because we generally recognize revenue from cloud subscriptions ratably over the term of the subscription agreement, near term changes in sales may not be reflected immediately in our operating results. We may not achieve market acceptance of our pre-built solutions, which may adversely affect our financial results. 11 If our platform fails to perform properly or there are defects or disruptions in the rollout of our platform updates or enhancements, our reputation could be adversely affected, our market share could decline, and we could be subject to liability claims. We rely upon Amazon Web Services, or AWS, to operate our cloud offering; any disruption of or interference with our use of AWS would adversely affect our business, results of operations, and financial condition. Our growth depends in part on the success of our strategic relationships with third parties. We employ third-party licensed software for use in or with our software, and the inability to maintain these licenses or errors in the software we license could result in increased costs or reduced service levels, which would adversely affect our business. If we do not or cannot maintain the compatibility of our platform with third-party applications that our customers use in their businesses, our revenue will decline. Because we collect and store personal information, domestic and international privacy concerns could result in additional costs and liabilities to us or inhibit sales of our software, and subject us to complex and evolving federal, state, and foreign laws and regulations regarding privacy, data protection, and other related matters. If our platform fails to function in a manner that allows our customers to operate in compliance with regulations and/or industry standards, our revenue and operating results could be harmed. We are subject to governmental export and import controls and economic and trade sanctions that could impair our ability to conduct business in international markets and subject us to liability if we are not in compliance with applicable laws and regulations. Any failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results. Portions of our platform utilize open source software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our business. Our ability to use net operating losses to offset future taxable income may be subject to certain limitations. The dual class structure of our common stock and the existing ownership of capital stock by Matt Calkins, our founder and Chief Executive Officer, have the effect of concentrating voting control with Mr.

Nothing is more transformative for an organization than improving their processes. Appian has both the platform and the expertise to enable enterprise transformation. The Appian Platform Appian is a leading platform for process orchestration, automation, and intelligence.
Removed
The past year has ushered in a whole new economy, in which AI promises to transform workflows to drive efficiency and innovation. As we enter 2024, the focus will shift from exploring these technologies to actively leveraging them to innovate with new products, services, and value creation for customers and employees alike.

Added
Appian tightly integrates data fabric; robotic process automation, or RPA; intelligent document processing, or IDP; generative artificial intelligence, or generative AI; artificial intelligence agents, or AI agents; low-code design; application programming interfaces, or APIs; business rules; and process intelligence capabilities in a single platform.
Removed
We see a human-centric future for AI, one of teamwork rather than replacement, where AI adds value to data and employees, and where all customers and businesses—not big tech—are the winners. We recognize AI is not a standalone technology. It is highly dependent on two foundational technologies: data and process.
Added
These capabilities are unified and scalable, meeting enterprise demands and easy to change as requirements evolve. • Process Orchestration: The Appian platform coordinates tasks between AI, automation, and humans to ensure processes run efficiently and intelligently. RPA enables customers to build bots with low-code to automate repetitive manual tasks.
Removed
Data is the intellectual fuel for AI, empowering it to make smart, informed decisions. The more data AI gets, and the better that data is, the better the AI answers may be. Data was already among the most important assets for leading organizations; now, it’s worth more than ever.
Added
Appian AI agents extract data, process documents, and initiate processes at scale. API integration easily connects systems with low-code design tools and hundreds of prebuilt connections. • Data Fabric: Appian’s data fabric is an integrated data layer that unifies data across systems without requiring companies to migrate their data.
Removed
Process is the necessary layer for customers to create a mixed autonomy, routing tasks between humans and AI automations. We believe customers will increasingly rely on AI to accelerate common tasks but must ensure humans maintain control and oversight of business processes. We offer leading expertise in all three areas.
Added
Appian empowers users to explore data in real-time, build reports, and get AI-powered insights for smarter decision-making. Our patented data fabric technology supports both analytical and transactional workloads, which allows users to build applications that create and update enterprise data. It also includes row-level security rules to enforce access controls at every level.

Removed
We weave all three elements together in a single product that empowers our customers to achieve rapid value. 4 The Appian Platform The Appian Platform enables customers to easily design, automate, and optimize their mission-critical business processes, driving continuous innovation.
Added
Companies can use AI to monitor processes, identify issues, and get intelligent recommendations for optimization. • Artificial Intelligence: We believe the key to unlocking AI’s full potential is embedding it inside a business process. Process is where business happens. It’s where companies make decisions, save and spend money, serve customers, and scale business operations.
Removed
Through Appian's unified platform, customers can swiftly develop new digital solutions using a low-code approach, creating applications and workflows tailored to their unique business requirements. We catalyze the AI-driven enterprise by combining AI, data, and process capabilities in a single platform. Our low-code design experience delivers solutions for customers quickly.
Added
When AI operates within processes, it gains purpose, governance, and accountability—all essential to delivering value from AI. Appian can embed AI into every process, which gives AI the context and actions it needs to accelerate outcomes for the enterprise. 4 Appian delivers six key benefits with our “AI in process” approach: 1. Process makes AI easy.
Removed
It is unified, reduces training times and dependencies on additional tools, and is built for enterprise-grade applications requiring high reliability, security, and scalability. Appian’s architecture is based on our four critical capabilities: process automation, data fabric, total experience, and continuous improvement through process mining. Process Automation We are a long-time innovator in process automation.
Added
Deploying AI in isolated projects is complex and costly. By embedding AI within a process, enterprises can easily access valuable AI capabilities when and where they need them. 2. Process gives AI structure. AI is only as useful as the structure surrounding it. A process gives AI defined goals in a structured flow of work.
Removed
Our process capabilities are crucial in orchestrating AI alongside humans and systems within business environments. Our business rules technology allows organizations to encode and enforce policies and routing decisions that reduce risk, while our native RPA and AI enable organizations to automate process steps to deliver greater efficiency and increase customer and employee satisfaction.
Added
AI can work alongside humans and automation tools, escalating issues so humans always maintain oversight and control. 3. Process gives AI data. AI is nothing without data. But most enterprises struggle to feed AI complete data from across systems, while still ensuring privacy and maintaining access privileges.
Removed
We sell our platform as a unified set of automation technologies that accelerates customer implementation times and return on investment. Data Fabric Data is at the heart of AI's transformative power, and we excel in enabling customers to utilize data effectively.
Added
By integrating AI into processes, enterprises ensure AI receives quality, real-time data from all systems. Organizations can enforce privacy controls to prevent unauthorized access and optimize data governance to comply with regulations (such as GDPR, HIPAA, etc.). 4. Process makes AI safe. AI is powerful, but no one wants to give AI free reign over their enterprises.
Removed
By leveraging our sophisticated data fabric, organizations can unify data across the enterprise into a single virtual data model, empower users to make informed decisions, and train AI models, transforming reservoirs of enterprise data into a source of powerful innovation.
Added
Processes provide crucial safety mechanisms, including human approval steps for high-risk actions and escalation paths to ensure AI errors don’t cause harm. Additionally, activity logs make auditing and compliance simple for organizations with strict regulatory requirements. 5. Process makes AI measurable. For many enterprises, AI is a black box, which can’t be measured for impact.
Removed
This capability is pivotal in feeding AI algorithms and human workers with quality data and extracting meaningful insights that drive business decisions. In addition, the secure infrastructure of our data fabric architecture is designed to provide a safe environment for storing and handling sensitive information, ensuring confidential data remains protected.
Added
Appian processes track every AI action, allowing organizations to measure performance, identify bottlenecks, and optimize outcomes. 6. Process makes AI enterprise-grade. A process provides the necessary infrastructure to scale AI use. The right tooling puts AI to work with security certifications, enterprise scalability, and other capabilities such as process orchestration, automation, and intelligence.
Removed
Total Experience Total experience is about creating superior experiences across desktop and mobile devices for every user, uniting customers and employees in a seamless workflow.
Added
Processes take AI from a collection of disconnected pilots to an enterprise-wide capability. Appian’s unified approach delivers all the capabilities leading organizations need to orchestrate their business processes in one place.
