AI-Ready

As AI becomes an essential part of modern applications, we are pursuing a dual opportunity: enabling AI workloads for our customers and leveraging AI to enhance our platform’s usability and capabilities. Our platform offers semantic caching and edge data stores to speed up AI workloads, while support for real-time messaging and pre-processing of visual data for AI models reduces latency and improves efficiency for AI applications. Fastly’s platform also includes capabilities for managing agentic AI and AI bot traffic, and controlling services through natural language interfaces.

Platform Differentiators

The evolution of Fastly’s platform is powered by a set of core differentiators. These differentiators have allowed us to rapidly adapt to changing market needs.

Robust architecture: Our network is comprised of robust, high-density POPs (points of presence) designed to minimize footprint and colocation costs while delivering content closer to end users. Strategically located near major cloud providers and peered with Internet exchanges worldwide, our POPs are designed to achieve optimal performance with fewer nodes than traditional architectures.

Software-controlled: We built a smarter network using fast switches and server-layer routing intelligence, allowing us to deliver real-time responses by optimally routing customer traffic. Our network also supports origin health checks for CDN and Compute services, which are designed to monitor and direct traffic away from unhealthy backends to maintain service reliability.

Resilient by design: Our network is designed to withstand common performance degradation and connectivity issues with internet transit providers. Fast Path Failover provides automatic detection and rerouting of underperforming edge connections at the transport layer. Precision Path monitors origin connections and reroutes traffic in real time to the best available path. Autopilot, our automated egress traffic engineering solution, allows us to reliably manage high-traffic events without manual intervention. When it comes to protecting against DDoS attacks, our Adaptive Threat Engine is designed to enhance platform resilience by automatically detecting and mitigating attacks in real time, using advanced behavior modeling and traffic analysis to stop threats even when attackers rotate IPs.

Fully programmable: We have built a fully programmable platform that gives customers comprehensive control over how their content is cached and how it responds to end-user requests. Using our flexible APIs, customers can make configuration changes themselves, rather than relying on professional services. This results in faster end-user experiences and cost savings for our customers, while unlocking developer innovation.

Granular visibility: Customers need continuous insight into the status of their apps and services. Across our product lines, we provide real-time logging, rich metrics, alerts and dashboards enabling faster, data-driven decision making. Software engineers can monitor performance, detect anomalies, and troubleshoot issues faster using these tools, maximizing availability and performance for their apps and services. Fastly’s granular visibility enables customers to iterate quickly on new releases, bringing innovations to market faster so they can stay ahead of competitors.

DevOps-friendly: We make it easy for customers to integrate Fastly into their DevOps workflows through rich APIs and support for platforms like Terraform, Amazon S3, and Google Cloud Storage. Combined with our configurability and visibility, these integrations enable developers to include Fastly in their continuous integration and deployment processes, accelerating and optimizing software and feature releases to enable their business goals.

Network Services

Fastly is an extension of our customers’ infrastructure. Our Network Services are designed to speed up and optimize the delivery of web and application traffic while ensuring developers and engineers do not lose visibility or control. Whether customers are looking to deliver engaging web and streaming experiences to their users, move apps to the cloud, or scale their DevOps practices, our Network Services provide the speed, security, and flexibility customers need.

Content Delivery Network

•Dynamic Site Acceleration. Speeds up requests and responses between cache nodes in our Points of Presence (“POPs”) and customers’ origin servers to serve their dynamic web and mobile content faster.

•Origin Shield. Allows us to designate a specific POP to serve as a shield for a customer’s origin servers. When web content is refreshed and multiple end users request the new content simultaneously, a deluge of requests can hit a customer’s origin server. This can result in poor web or application performance. With Origin Shield, we collapse all these content requests into a single request and hold it in queue at the Origin Shield POP. That allows us to retrieve the new content from the customer’s origin server only once, and then serve it to all end users who requested it. This approach reduces costs for our customers, while improving performance for their end users.

•Instant Purge. Allows customers to clear the cached copy of their content globally in milliseconds, not seconds. We allow customers to send a command to our platform that invalidates an old version of their content throughout our global edge infrastructure. This causes a new version of content to be retrieved from the application server the next time it is requested. This feature enables our customers to serve highly dynamic content at the edge faster, facilitating delightful application experiences. Rapidly changing content like shopping cart items, flight search results, sports scores, or current weather conditions in any given location can all be served faster from the network edge.

•Surrogate Keys. Allows customers to fine-tune purging by tagging related objects across their site with a key name and description, then purging by that key. Customers can purge their entire site of a given object or set of objects all at once, without impacting performance. For example, customers could purge any images and content related to discontinued sale items, discounted products, or outdated news across their site all at once.

•Programmatic Control. Provides direct programmatic control of edge delivery services to our customers, allowing them to precisely control what content is cached, for how long and when it should be refreshed. Combined with comprehensive APIs, this allows our customers to build, test and deploy custom logic, using their own development, test and deployment environment, for even the most complex digital experiences.

•Content Compression. Compresses content with technologies like Gzip and Brotli, providing direct performance improvements and a more responsive web experience for end users.

•Reliability Features. Support the availability of customer content with features including origin health checks, a ‘grace mode’ feature that will continue serving content even when customer origin(s) fail, Multipath TCP, and real time error dashboards and API feeds that are backed by a 100% uptime Service Level Agreement (“SLA”).

•Fanout. Enables customers to push data in real time to many users, such as synchronous communication of messages in a chatroom, server updates to Internet of Things (“IoT”) devices and other types of data between devices. Real-time messaging is used in a wide range of data streaming applications, including IoT, live commenting, end-user notifications, chat and more.

•Domainr. Provides customers with a real-time and programmatic means for checking domain availability. A programmatic solution for verifying trust for domains is especially useful for platform customers. Using Domainr's APIs, customers can embed these functions directly into their workflows.

10

•Modern Protocols and Performance. Helps our customers, and the Internet in general, receive the best possible performance regardless of user device, connectivity or location though supporting the development of next generation web technologies and protocols such as HTTP/3, QUIC, client hints and HTTP prioritization.

•Staging Environment. Allows customers to test changes to their CDN or Compute service configurations in a staging environment before deploying them to the production network. This helps identify and resolve potential issues earlier in the development process. Staging features are automatically enabled for use in the Fastly API, command line interface, and via Terraform.

Video / Streaming

•Live Streaming. Delivers millions of concurrent high-quality live streams. It can deliver online content using major HTTP streaming formats while providing real-time feedback to optimize viewer experiences. In addition, we partner with multiple video platform vendors to improve the flexibility and scale of live-streaming workflows and reduce the total cost of ownership for customers.

•Video on Demand. Reduces the load on origin servers and accelerates time-to-first-frame by caching and rapidly delivering Video on Demand content. Our on-the-fly-packaging feature optimizes streaming media on demand and facilitates immediate playback, thus enhancing viewer experiences across regions, devices, and platforms.

•Media Shield. Large streaming customers typically use multiple CDNs for media delivery for redundancy and protection. Our Media Shield product supports these efforts and can reduce the total cost of ownership while also regaining lost visibility and improving performance. By collapsing multiple origin requests for identical content across several CDNs, content can be streamed faster, more efficiently, and with a significantly smaller infrastructure burden.

•Cache Reservation. Allows large streaming customers to reserve cache space at Fastly’s edge for high traffic events. By prioritizing a customer’s content cache storage, Cache Reservation allows that content to stay in cache for longer, minimizing content eviction in multi-tenant environments. It also helps reduce cloud egress costs by optimizing origin offload from any CDN, including Fastly.

•Live Event Monitoring. With real-time monitoring, streaming delivery, request collapsing, capacity planning, and flexible deployment, Fastly Live Event Monitoring gives customers insights into their live streaming performance and the ability to troubleshoot immediately, all while reducing costs.

Object Storage

•Object Storage. Fastly Object Storage is an Amazon S3-compatible large object storage solution that works seamlessly with both our CDN and Compute services. Customers can store large file sizes, improving latency, increasing cache hit ratios, and reducing egress charges. Objects stored in Object Storage are accessible via an S3-compatible interface. Our on-demand migration feature enables customers to only migrate their required working set of data, reducing egress charges from their source provider.

Load Balancing

•Load Balancer. Manages HTTP/HTTPS requests to a customer’s origin using granular content-aware routing decisions. We allow customers to manage traffic across multiple IaaS providers, data centers, and hybrid clouds. We also provide improved performance and cost savings over ADCs, especially during a spike or surge in traffic.

Image Optimization

•Image Optimizer. We offer a real-time image manipulation and delivery service and store transformations at the edge. When an image is requested, we resize it, adjust quality, crop/trim, change orientations, convert

11

formats, and more, all on demand. Transforming images at the edge eliminates latency and reduces traffic to origin servers, allowing customers to save on infrastructure and egress costs.

Origin Connect

•Origin Connect. Ideal for companies moving more than one gigabyte of data per second, such as media, video, and streaming companies, Origin Connect provides a direct private network connection between an organization’s origin server and an Origin Shield POP. This is an effective way to lower transit costs, reduce engineering complexity, and improve reliability for high-volume streaming content.

Security

Customers across multiple industries rely on Fastly to help rapidly secure their business-critical websites, apps, and APIs. Our modern approach to application security provides the accuracy, flexibility, and ease-of-use that our customers value and expect. Fastly provides a suite of security solutions focused on protecting websites, apps, and APIs from unwanted activity, including DDoS attacks, application layer attacks, and abusive behavior from automated software such as AI crawlers. This solution suite is designed to be real-time, scalable, and customizable, offering customers the ability to tailor and adapt their security to their unique and evolving business needs.

Next-Gen WAF. Our next-generation Web Application Firewall protects applications from malicious attacks that seek to compromise apps and APIs. Our context-aware solution requires no tuning, reducing our customers’ time to deploy software changes, and is more accurate than the traditional rule or signature-based approaches. Our WAF can be installed in any infrastructure: cloud, virtual private cloud, container, on-premise data center or hybrid environments or at the edge. Key features include:

•Bot Management. Bad bots can perform content scraping, tie up system resources, perform account brute forcing and other harmful actions. Our solution (available as part of our Next-Gen WAF) monitors web application and API traffic for automated bot activity, allowing customers to automatically block malicious bot-generated web requests, while providing access for wanted or verified bots. Additional advanced bot management features are available in our separate Bot Management product, described below.

•API Protection. Attackers often target sensitive APIs with malicious activity like attempting to validate stolen credit cards, perform ecommerce gift card fraud or obtain patient healthcare records. We help customers stop API abuse by enabling them to monitor for unexpected values and parameters submitted to API endpoints, and block unauthorized requests.

•Account Takeover Protection. Account takeover occurs when attackers use authentication credentials to take over legitimate user accounts. Attackers test stolen credentials in an automated manner called “credential stuffing.” Our Account Takeover Protection empowers customers to automatically block and alert on credential stuffing attacks.

•Deception. Our advanced deception feature blocks malicious login attempts while also misleading attackers with fake “invalid username/password” responses. Attackers are left frustrated, thinking their credentials are bad and retrying them without realizing they have been detected. This feature is currently available for our Next-Gen WAF, and our goal is to embed deception into both new and existing security products to create end-to-end attacker tracing across customer’s production environments.

•Advanced Rate Limiting. Advanced Rate Limiting enables customers to stop malicious and anomalous high volume web requests and reduce resource consumption while allowing legitimate traffic through to application and API endpoints—doing so means companies can provide a superior customer experience that scales to meet increasing demand.

Bot Management. Fastly Bot Management is an add-on service that provides customers with visibility into bot traffic, allowing them to differentiate between good and bad bots. They can then enforce rulesets and policies in the Fastly Next-Gen WAF control panel. Key features include AI Bot Management for controlling AI bot access, advanced client-side detection of sophisticated automated attacks, and support for dynamic challenges with Private Access Tokens (“PATs”), which allows for verification of legitimate users without relying on CAPTCHAs. Rather than

12

blocking all bots, our approach supports customers’ business goals by giving them granular control to block malicious bots while allowing legitimate automated traffic, such as search engine crawlers or monitoring tools, to access their services.

API Security. Fastly has a set of capabilities designed to help customers better protect their APIs. API Discovery automatically and continuously finds, collects and organizes customer API traffic across their Fastly services into one manageable interface. API Inventory allows customers to save and customize an accurate, detailed, and continuously-updated API inventory from the latest traffic surfaced in API Discovery. Being able to review and set aside APIs that are behaving as expected allows customers to more easily identify APIs which need security attention.

Client-Side Protection. Fastly Client-Side Protection helps our customers meet PCI-DSS compliance requirements. It provides real-time monitoring and protection against unauthorized modifications to client-side scripts and response headers, helping businesses secure sensitive customer data and maintain compliance.

Fastly DDoS Protection. Fastly’s DDoS Protection provides enhanced application-layer defense against DDoS attacks without requiring any upfront tuning. When unexpected volumetric events occur, our proprietary Adaptive Threat Engine leverages advanced, automated pattern analysis—including machine-learning–style behavior modeling—to determine legitimacy. If an attack is detected, it analyzes a comprehensive set of traffic characteristics to identify the attacker and quickly mitigate their attacks, even if IPs are rotated. Fastly DDoS Protection also features a zero-attack-fee billing model, ensuring customers are never charged for attack traffic.

TLS Encryption

•Transport Layer Security (“TLS”). As part of our standard product, our platform terminates HTTPS connections at our network edge, offloading encrypted traffic from our customers’ web servers for better performance. Predefined roles allow customers to more precisely manage TLS access without having to grant unnecessarily broad permissions. We also provide a number of different certificate procurement and hosting options.

•Platform TLS. Our Platform TLS offering is designed to allow customers with multiple web properties to manage TLS certificates at scale, while enabling a fast, secure experience for their end users. It supports delivery and management of hundreds of thousands of certificates, supported by our worldwide TLS termination and acceleration solution.

•Certainly. Certainly is our own publicly-trusted TLS Certification Authority. Fastly customers can use a certificate issued by Certainly to secure any website or API endpoint served by our CDN.

Privacy. Fastly offers several privacy enablement capabilities. Our OHTTP Relay solution provides fast, reliable separation and isolation of end user data, while passing along non-identifying requests to the business server. Fastly’s OHTTP Relay is designed to enhance online privacy for users of several of the largest internet vendors. Fastly has worked with others to develop and standardize the technology behind PATs. As an alternative to CAPTCHAs, PATs provide better user privacy by helping ensure there is no leakage of non-essential data.

Compliance. Our caching and delivery services are designed and measured against key audit and regulatory standards to help customers manage their compliance, including the Health Insurance Portability and Accountability Act (“HIPAA”), the European Union's General Data Protection Regulation (“EU GDPR”), the United Kingdom’s GDPR (“U.K. GDPR”), and industry standards like the PCI Data Security Standard and SSAE-18. Fastly is also certified to the ISO/IEC 27001:2022 standard for its Information Security Management System, and our Next-Gen WAF is FIPS 140-3 compliant for organizations that process sensitive government information or operate in regulated sectors.

AI Capabilities

AI is becoming an increasingly important part of modern application development. We have extended our powerful, programmable platform to include new products and feature enhancements that help customers accelerate, protect, and optimize their AI-driven workloads.

AI Bot Management. Fastly AI Bot Management is a feature within our Bot Management offering. It provides visibility and control over automated traffic by using behavioral analysis and threat intelligence to identify and classify AI bots. Customers can gain insight into how AI bots access and scrape their content, enabling them to evaluate whether this activity aligns with their business goals—such as generative engine optimization—or constitutes unauthorized use. They can then take targeted actions, including blocking, rate-limiting, or allowing this AI bot traffic. AI Bot Management is also integrated with Tollbit and other monetization vendors, to monetize AI bot scraping of customer content. The Tollbit integration allows customers to redirect AI bots to a paywall for token verification. AI bots with valid tokens are granted access to content, while AI bots without valid tokens are required to pay for access.

Edge Data Storage. Fastly Key-Value Store and Object Storage are edge data storage solutions which can help optimize AI workloads. Key-Value Store supports semantic caching of large language model (“LLM”) responses, allowing applications to instantly serve relevant results while reducing calls to expensive, high-latency model APIs. Object Storage supports AI workloads by providing a cost-effective way to store and serve large datasets for LLM training, enabling organizations to scale AI model training while reducing storage costs.

Fanout. Fastly Fanout simplifies the delivery of real-time workloads by managing complex, persistent client-server communications at the edge.

Our Growth Strategy

Our growth strategy focuses on making our edge cloud platform accessible to a broader base of customers through enhancing our product experience, investments in technology and infrastructure, attracting new business, growing partnerships, and vertical expansion. Key elements of our growth strategy include the following:

•Product strategy. Built upon a strategy of durable innovation, our programmable edge cloud platform creates a consistent and predictable pipeline of innovation. We plan to expand existing product lines like Network Services and Security, and expect to further incubate newer products for future growth.

17

With the goal of making it easier for customers to do business with us, we continue to build out a single, unified platform where they can access and manage all their Fastly services in one place. Our security products - DDoS Protection, Next-Gen WAF, Bot Management, Client-side Protection, and API Security - are available on one platform, and easily accessible through the Fastly Control Panel. We have also taken steps to further simplify customer onboarding and service usage, through easy access to self-training information from within the Fastly app, and more code samples and support.

•Expansion into additional vertical markets. Our platform offers a broad range of capabilities. Our differentiated high performance and low-latency delivery network and edge compute platform, as well as enhanced security capabilities, allows us to serve the needs of our existing customers and continue to add customers from a diverse set of industries.

•Expand existing customer relationships. Over time, our customers have expanded their use of our platform. In more technically savvy organizations, software engineering leaders have championed our solution, paving the way for us to engage with business decision makers. For more traditional organizations, we are often brought in to initially help facilitate a move to the cloud and from there we extend our product to support many other use cases. We plan to continually increase wallet-share over time for existing customers as we build out new products and features, and as customers continue to fully recognize the value of our platform.

•Grow our technical partner ecosystem. We operate between and complement the “big 3” origin cloud platforms, Amazon Web Services (“AWS”), Microsoft (Azure), and Google Cloud Platform, and a growing community of companies that provide big data, AI, and security solutions. In this sense, we act as the unifying layer for a growing number of cloud services. As customers consume more cloud and software as a service (“SaaS”) offerings, we can create additional value and grow with these partners.

•Attract new customers. With new product innovations, additional vertical focus areas, growing partners, and an optimized go-to-market engine, we plan to attract new business and continue to grow. In addition, we can help new customers accelerate, protect, and optimize their AI-driven workloads, AI-generated software, and traditional applications that increasingly experience agentic interactions.

•International expansion. As our customer base grows, we plan to scale our network to bring edge computing closer to where our customers are. We believe significant opportunities exist for international growth.

Partner Ecosystem

Partners are one of the ways Fastly creates new value for customers, reaches new markets, and builds things we couldn’t do alone. Our strategy is to create economic, reputational, and technical value with our partners and to be the engine that powers their revenue and growth. To achieve this, we partner with a number of global channel partners who offer our performant and secure solutions on top of their own value-added services. We work with top cloud service providers to combine our complementary products and services and to offer streamlined procurement through cloud marketplaces. We also partner with a number of third-party technical partners to extend our capabilities across new markets and use-cases. Ultimately, partners help our customers by:

•Providing a complete suite of value-added services and solutions

•Offering flexible and efficient engagement and purchasing models

•Acting as a single point of contact; and

•Extending geographic coverage and support.

Channel Partners. Fastly’s partners take full advantage of our powerful, open, and programmable edge cloud platform to build and deliver high-margin services and value-added offerings for end customers. Our partner program operates like a flywheel to innovate, market, sell, and deliver solutions jointly with our partners. The three primary channel partner types we work with are:

•Referral partners: Recommend Fastly products to their customers for a commission and include partners like agencies and consultants.

18

•Reseller partners: Act as a reseller to offer additional value on top of Fastly’s products and services and include partners like value-added resellers, system integrators, and more.

•MSP and MSSP partners: Managed Service Providers (MSP) and Managed Security Service Providers (MSSP) can earn technical certifications to provide certified implementation services and/or embed Fastly technology to enhance their SaaS or Platform as a Service offerings.

Partners work with Fastly’s sales and presales teams to scale sales cycle support. This helps expand our worldwide network of partners dedicated to protecting and delivering customers’ content. We have expanded the reach and breadth of these partners to include cross-selling delivery and security products. We have made significant investments in this area by adding additional channel sales and marketing resources, technical training and enablement, partner discounts, and an elevated partner program to offer partners even more benefits.

Cloud Partners. We integrate with major cloud providers to enhance their services and create solutions that are powerful, scalable, and secure. We have exclusive Private Network Interconnects (PNIs) and peering arrangements with key cloud providers such as Google Cloud Platform, AWS, and others to eliminate or minimize egress fees, enhance security, and improve overall performance. We are also available for purchase on the Google Cloud Marketplace and AWS Marketplace which can help eliminate the need for customers to have separate billing arrangements and makes Fastly services eligible for Google Cloud and AWS committed spends. We have strong go-to-market relationships with our cloud partners which allow us to access the benefits of their partner programs like joint business planning, co-selling, account support, added marketing funding, and more.

Integration Partners. We integrate with a number of third-party partners who offer complementary technology across a number of strategic use-cases and industries. These partners help expand our reach into new markets by offering customers a solution that seamlessly integrates with their existing technology stack making our technology even stickier. Here are some examples:

•Security: Our Next-Gen WAF integrates seamlessly with a broad ecosystem of third-party tools, enabling customers to streamline workflows, strengthen DevOps processes, enhance security visibility, and improve operational efficiencies. Our Next-Gen WAF supports Kubernetes and service mesh and API gateway technologies such as Envoy, Istio, and Ambassador to accommodate modern microservices architectures. It is also compatible with major cloud and platform providers, including Amazon Web Services, Microsoft Azure, Heroku, and VMware Tanzu.

The Fastly Next-Gen WAF is also integrated with A10 Networks ADC appliances enabling optional application security controls for their customers. This partnership expands our reach to new customer segments, including organizations that primarily operate in private data centers, maintain a smaller public cloud footprint, or are located in different geographic regions where Fastly has had more limited historical penetration.

•Logging & Analytics: Our real-time logging feature integrates with more than 20 logging endpoint partners to allow customers to customize and visualize their edge data for better monitoring of performance and security anomalies. Examples include DataDog, Looker (Google Cloud), SumoLogic, Logentries, Google Cloud Platform (GCP), Microsoft (Azure Blob Storage), and more.

•Compute: We work with a growing ecosystem of partners who are tapping into our powerful Compute serverless technology to extend their solutions across a variety of different use-cases.

•Media & Entertainment: We have partnerships across a number of technology providers in the media and entertainment industry to enhance our edge platform’s performance features, modern security offerings, and real-time metrics.

Competition

Our platform spans several markets from cloud computing and cloud security to CDNs. We segment the competitive landscape into six key categories:

19

•Legacy CDN platform solutions like Akamai;

•Application and API security vendors like Akamai, Cloudflare, F5, and Thales (Imperva);

•Point CDN players like Bunny CDN, CDNetworks, CDN77, and Qwilt;

•CDN providers that also offer serverless edge compute functionality like Akamai and Cloudflare;

•Public cloud providers that have added CDN and WAF capabilities like Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft (Azure); and

•Traditional on-premise, data center appliance vendors for load balancing, WAF, and/or DDoS like F5, Thales (Imperva), and Radware.

The principal competitive factors in our market include:

•platform functionality, scalability, performance, ease of use, ease of integration and programmability, reliability, security availability, and cost effectiveness;

•global network coverage and availability;

•ability to support modern application development processes and utilize new and proprietary technologies to offer services and features previously not available in the marketplace;

•ability to identify new markets, applications, and technologies;

•ability to attract and retain customers;

Our Culture and Human Capital Resources

Our Values

Technology has the potential to make a radically positive impact on the world, and we aspire to improve human lives through our work. We were founded on strong ethical principles, and have intentionally grown values-first, scaling our workforce, services, customer portfolio, and investment partners purposefully. Our values guide our hiring practices as well as the ethics we are committed to upholding as we scale. We believe that as a result of our values, we have been able to identify, attract, engage and retain great people. We want to serve the very best of the Internet. We choose to work with customers that we believe have integrity, are trustworthy, and do not promote violence or hate. Our eight core values define who we are and how we choose to grow, hire, train, work, communicate, make decisions, support each other, and serve our customers.

Our Hiring Strategy

At Fastly, our ability to innovate and compete in the edge compute, delivery, security, and observability markets is directly tied to our ability to attract and retain specialized technical talent. We view our workforce as a strategic extension of our platform architecture: distributed, resilient, and high-performing.

Cultivating Technical Excellence and Belonging We are committed to building a workforce comprised of highly qualified individuals who reflect our core values. Our engineering recruitment focuses on attracting world-class experts in the foundational technologies of the internet, including Rust, WASM, and high-scale network security to foster our edge computing innovation.

Strategic Talent Pipelines and Development To maintain a competitive edge and a service-oriented culture, we leverage non-traditional talent pipelines. A key component of our strategy is our internal mobility program, which identifies high-potential talent from various backgrounds and technical training programs for our support organizations. These individuals often transition into broader roles across the company, infusing our product and engineering teams with a deep, customer-centric mindset and practical operational experience.

Total Rewards and Retention To attract and retain our highly qualified employees and executive team, we offer a competitive compensation program designed to align employee interests with long-term company success. This program includes a combination of competitive base salaries, performance-based incentives, comprehensive benefits, and a robust equity compensation component intended to motivate and reward long-term commitment and innovation.

21

We are building a global workforce and an inclusive culture that empowers and supports our employees and customers, regardless of background. We onboard all new employees with training programs on our values, our business, and important policies, including our Safe, Welcoming, and Productive Work Environment Policy. Annually thereafter we provide employees with code of conduct and security awareness training, a learning reimbursement program and performance evaluations. Our employee engagement efforts currently include company-wide newsletters and all-hands meetings, through which we aim to keep our employees well-informed and increase transparency. Our Employee Resource Groups are open to all employees and focus on making Fastly a better place where all employees are included, valued and engaged. We also use employee engagement surveys to collect employee feedback and assess the effectiveness of our culture, our strategy, and various health and well-being programs.

Employees

As of December 31, 2025, we had a total of 1,140 employees worldwide and 258 employees located outside of the United States; 47% of our employees resided within 50 miles of a Fastly office and 53% of our employees worldwide were considered remote, which means they resided more than 50 miles from a Fastly office or in locations where we do not have a Fastly office. We will continue to search for the best possible talent for every role and cultivate best-in-class in-office and remote employee experiences.

Our Organization

Sales & Marketing

Sales and marketing work closely to attract new customers and expand the adoption of our platform to help customers drive business outcomes.

We are building a go-to-market engine that scales, becomes increasingly more efficient, and is nimble enough to continue to grow our business in four dimensions:

•Customer logo acquisition

•Expansion into additional vertical markets and within existing customers

•Partner ecosystem leverage

•International expansion

Fastly’s marketing efforts have a significant impact on new logo acquisition, demand generation, and brand awareness. We are focused on optimizing the return on our marketing investment to drive demand across our portfolio and regions.

Our sales and marketing organizations collaborate to cultivate customer relationships with developers and business leaders at enterprises and technology-savvy organizations to drive revenue growth. We have geographically-based sales teams that continue to enhance our value-based selling methodology. Our land and expand sales strategy for enterprise customers has successfully demonstrated our platform’s capabilities, and our customer support enables broad adoption of our technology within an organization.

Customer Support

We have designed our products and platform to be self-service and require minimal customer support. Customers are automatically covered by our Standard support plan as soon as they sign up with us. They can file a ticket with the support team, and access documentation including online FAQs, API references, and configuration guidelines. Our support approach is unique and built with developers in mind. Our first-line support employee typically has an engineering background and is highly technical.

We also provide several options for premier, hands-on support from a team of highly-technical senior support engineers and technical account managers. They act as a single point of contact for our support, product, and engineering teams. Our support model is global, with 24/7 coverage and support offices located in North America, EMEA, and APAC.

Research & Development

Our research and development team members are responsible for the design, development, and reliability of all aspects of our edge cloud platform. Continuous improvement and innovation are core to our DNA, and these efforts are baked directly into our service life cycle. Scale, performance, security, and reliability are core functional requirements of everything we build into our platform to serve our customers.

Our philosophy of customer empowerment guides our research processes. Our product managers regularly engage with customers and developers, DevOps and site reliability engineering communities, as well as our internal stakeholders and subject matter experts, in order to understand customer needs. Our engineering team includes experts with deep experience who intimately understand customers’ technical challenges and build solutions that deliver outcomes our customers value the most.

Throughout the strategic design and build phases of our product life cycle, our development organization works closely with our product, infrastructure, operations, and compliance teams to design, develop, test, and launch any given solution. We strive for a balance of rapid iteration without compromise on the core functional requirements that our customers expect: scale, performance, security, and reliability.

As of December 31, 2025, we had 415 employees in our research and development group. Our research and development expenses were $162.7 million for the year ended December 31, 2025.

Infrastructure

Our infrastructure team is responsible for the design, deployment, and maintenance of the servers and network hardware that form the foundation of our mission critical edge cloud environment. We invest in research into global Internet geography to identify optimal colocation site selection, network partner identification, and network-to-network interconnection opportunities. These activities allow us to connect in close proximity to core Internet backbones and Internet service providers, thereby enhancing network performance. We carefully evaluate and test hardware from leading server, network, and component manufacturers to assess their compliance with our workload performance, system efficiency, and mean time-to-repair standards. In our process, we evaluate commodity server and network platforms to avoid vendor lock-in, while optimizing the mix of components in an effort to improve efficiency and optimize our capital expenditures. We intend to grow the number of data center colocation sites as traffic on our network grows and as demand for new markets justify investment.

Trust

Our security, compliance and data governance teams, as well as other departments across the company, continually iterate on our trust programs to better meet growing customer needs, updated regulatory requirements, and the evolving security threat landscape. To help validate the controls that safeguard our platform and the data moving through it, we have expanded our portfolio of security and compliance-related assessments and certifications over time.

Intellectual Property

We rely on a combination of patent, copyright, trademark, and trade secret laws in the United States and other jurisdictions, as well as license agreements and other contractual protections, to protect our proprietary technology. We also rely on a number of registered and unregistered trademarks to protect our brand.

As of December 31, 2025, in the United States, we had 112 issued or allowed patents, which expire between August 2033 and March 2043, 5 patent applications pending for examination. As of such date, we also had 22 issued patents and one patent application published or pending for examination in foreign jurisdictions, all of which are related to U.S. patents and patent applications. In addition, as of December 31, 2025, we had 18 registered trademarks and no pending trademarks in the United States. As of such date, we also had 35 registered trademarks in foreign jurisdictions.

In addition, we seek to protect our intellectual property rights by requiring our employees and independent contractors involved in development of intellectual property on our behalf to enter into agreements acknowledging that all works or other intellectual property generated or conceived by them on our behalf are our property, and assigning to us any rights, including intellectual property rights, that they may claim or otherwise have in those works or property, to the extent allowable under applicable law.

23

Despite our efforts to protect our technology and proprietary rights through intellectual property rights, licenses, and other contractual protections, unauthorized parties may still copy or otherwise obtain and use our software and other technology. In addition, we intend to continue to expand our international operations, and effective intellectual property, copyright, trademark, and trade secret protection may be unavailable or limited in foreign countries. Any significant impairment of our intellectual property rights could harm our business or our ability to compete. Further, companies in the communications and technology industries own large numbers of patents, copyrights, and trademarks and frequently threaten litigation, or file suit based on allegations of infringement or other violations of intellectual property rights. We are currently subject to, and expect to face in the future, allegations that we have infringed the intellectual property rights of third parties. From time to time, we also receive demands for indemnification from our customers under the terms of our contracts with them for infringement of a third-party’s intellectual property rights.
