To Our Stockholders,

The last year has both highlighted the criticality of cybersecurity in every aspect of modern life and tested the foundational strength of our business. I am particularly proud of the way our employees have risen to the challenge of navigating this complex world where ransomware, breaches and nation-state threats regularly make the news. Tenable has been there, at every step along the way, to help our customers understand and reduce their cybersecurity risk, helping keep their businesses safer while accelerating their ability to innovate.

Our commitment to our customers

2021 was a year of milestones on many fronts, including a dramatic rise in high-profile cyber problems. As bad actors evolve from retrieving personal identification to crippling businesses and our communities, we remain completely focused on enabling our customers to answer the one question that is most critical to any digital enterprise: “How Secure Am I?” Our customer base has embraced digital transformation and all that it entails – shifting to the cloud and hyper-distributed modern applications. These same customers increasingly recognize that every new technology investment, every computer and asset type is interconnected and introduces risk. Tenable is working hand-in-glove with more than 40,000 organizations to help them expand their vulnerability management (VM) discipline to other areas of their infrastructure so they can understand and reduce their exposure to risk across software, identity and configurations.

During the year we delivered a platform that can provide our customers with the leverage they need by securing their tech investments so they can accelerate innovation. Tenable.ep brings our point solutions together to deliver the holistic insights and analytics modern enterprises require. We’re helping them understand how areas of attack are interconnected with an integrated solution and a complete picture of cyber risks. We are delivering unified visibility into code, configurations, assets and workloads. Because cyber risk is business risk, Tenable.ep helps organizations understand security concerns in the broader context of their business priorities. Tenable.ep combines the best of our past and present, establishing a better together framework that will serve our customers now as well as over the long term.

Our commitment to corporate social responsibility

In April of 2021, we published our first corporate sustainability report. We outlined our commitment to the environment, to our people and the investments we've made to foster this goal.

We know that Tenable is stronger because we bring different and inclusive perspectives to the table. What’s more, we are 100% focused on making Tenable a premier employer -- a company where people can thrive and succeed with meaningful careers. To that end, we instituted a number of initiatives to enhance the employee experience, including:

•Two days annually for career development,

•Enhanced learning opportunities, including diversity, equity and inclusion training,

•Remote work flexibility,

•Offices closed every Friday in August, and

•Annual equity grants to all eligible employees in good standing.

Nothing has made me more proud than watching the heroic efforts of our team throughout the last year. Their dedication to our customers, to our partners and to each other are constant. We will


Internet proxy voting will be provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions.
