A letter from our President and CEO

This past year at Ciena we made meaningful enhancements to our sustainability programming and drove progress toward our goals- progress that brings real value to our business. These efforts help us minimize our environmental impact, enabling our customers to meet their own sustainability and business goals and supporting our people and communities where we live and work. As the global leader in high-speed connectivity, we recognize the power of network innovation and the important role we play in connecting the world. This responsibility isn't something we take lightly. We embrace it and continue to embed it into every aspect of our company.

With the surge of cloud services and AI adoption, our reliance on connectivity continues to grow, as does the global demand for network capacity. Our focus remains on developing high-performance, energy-efficient solutions that enable our customers to meet their business needs while minimizing their environmental impact. In 2024, we achieved a 74.6% reduction

in our scope 3 emissions intensity per Gb/s of network capacity shipped compared to our 2019 baseline. This keeps us on track to meeting and maintaining our science-based target of reducing our emissions by 71.3% per capacity shipped in Gb/s by 2030, from 2019 levels, and directly translates into a smaller environmental footprint for Ciena and our customers.

Our product portfolio reflects this commitment to energy efficiency. Our WaveLogic™6 Extreme (WL6e) coherent technology hit the market in 2024, the first platform in the industry to deliver up to 1.6 Tb/s of

network capacity while requiring 54% less power per bit than the previous generation. We also continue to deliver novel, energy-efficient routing and switching solutions, shown by our WaveRouter® platform-the first of its kind to unify IP and optical in the metro while driving power efficiency. We also advanced our product sustainability through a significant packaging milestone in 2024: meeting our goal of using a minimum of 70% recycled content by weight across all product packaging. This allows Ciena and our customers to reduce waste within their supply chains.

Our software solutions, including the Blue Planet Intelligent Automation Portfolio and Ciena's Navigator Network Control Suite™(Navigator NCS), enable our customers to proactively monitor and troubleshoot network issues, reducing the need for truck rolls and optimizing energy use. Moreover, our services teams continue to work side-by-side with our customers, helping them optimize, transform, and modernize their networks for peak performance and maximum energy efficiency.

Our internal operations also reflect our commitment to environmental sustainability through investments in clean energy by sourcing renewable energy where direct grid access is available. We're proud to report a 91.9% reduction in our scope 1 and 2 emissions from our 2019 baseline, marking the second consecutive year of strong reductions. With continued progress, we will be on track to meet our science-based target of reducing our scope 1 and 2 emissions by 80.6% between 2019 and 2030.

Our people are the driving force behind Ciena's success, and we remain dedicated to fostering a supportive, inclusive, and empowering workplace where everyone can thrive. In 2024, this commitment was reflected in our strong overall employee engagement score of 83, five points above the industry benchmark, and in our low employee turnover rate of 3.7%.

To support our people, we provide a range of development opportunities to help them achieve their career aspirations. Our programs include Leadership and Manager Development programs that help our leaders become even more effective, support their teams, and enhance other soft skills. We also continue to offer a range of virtual learning opportunities and a mentorship program to further support our people's growth.

We also understand that our people thrive when they feel their best. In 2024, we continued to enhance our well-being programs through our benefits, Employee Assistance Programs, and resources available in our Work-Life Support Hub. In addition, our employee resource groups (ERGs) worked this year to foster a sense of community across our company, hosting events to engage all employees so that everyone feels included.

As a testament to our efforts, we earned recognition as a Great Place to Work in India as well as inclusion on the 2025 LinkedIn Top Companies list in Canada.

We believe in harnessing the power of our people and technology to drive positive impact in the communities where we live and work.

Our Ciena Cares volunteering and giving program empowers our employees to support causes they are passionate about. In 2024, our employees dedicated an incredible 37,048 hours of their time volunteering and, through employee giving and corporate matching, they generously donated $3.95 million to support organizations in

need. Notably, 50% of our employees actively participated in the Ciena Cares program during the year. This commitment led to Ciena receiving Benevity's People Power Goodness Award in 2024, recognizing our employee-driven culture of community impact.
