CCI Systems Wins 2021 Calix Partner of the Year Award, Showing Breakout Business Performance and Boosting Success for Multiservice Operators

Calix, Inc. (NYSE: CALX) today announced that CCI Systems has won the 2021 Calix Partner of the Year award. Announced at Calix ConneXions 2021 in Las Vegas, this award recognizes a partner for their overall business performance, level of innovation, and positive impact on Calix and CCI Systems broadband service provider (BSP) customers. An Elite Partner in the Calix Partner Community, CCI Systems has played an integral role in expanding the Calix presence in the U.S. multiservice operator (MSO) market, as well as with utilities and municipalities.

"We are honored to receive this prestigious recognition from Calix," said Mac Plymale, executive vice president at CCI Systems. "Our mission is to make life better by connecting people through innovative communication systems, and our partnership with Calix is central to achieving that. Together, we deliver a range of network solutions built on state-of-the-art technologies, supporting our customers' business, and contributing to their long-term success. We're excited to build on this partnership and capitalize on new opportunities."

Established in 1955, CCI Systems was selected based on their strong sales performance, business development capabilities, contributions to the development of Calix solutions, and commitment to partnership development. Highlights of the partnership include:

• Implemented Calix-based networks with 32 customers. Over the past two years, CCI Systems has implemented network solutions built on the Network Innovation Platform (AXOS®) and Intelligent Access EDGE portfolio with nearly three dozen service provider customers across a range of use cases. CCI is actively helping BSPs understand the benefits of migrating advanced routing and subscriber-based services closer to their subscribers to deliver a superior experience.
• Spearheaded new opportunities for Calix in the MSO market. With its deep relationships in the U.S. cable market, CCI Systems led the deployment of Calix FTTH solutions among Tier 2 and Tier 3 CATV (community antenna TV) companies, with an emphasis on fiber migration projects.
• Supported deployments with value-added professional services. In addition to technical solutions, CCI Systems provides professional services to ensure customers' success. Examples include assisting a large utility with grant funding and working with Calix on the design and the infrastructure to fulfill the project and developing a "municipality playbook" to simplify the quoting, installation, testing, and turn-up for municipal network projects.

"CCI Systems exemplifies what partnership is all about," said Stephen Eyre, vice president of partner ecosystem at Calix. "We leverage our joint experience, amplify our respective strengths, and share learnings to develop and implement advanced solutions that help our customers meet their business objectives. We are pleased to recognize CCI Systems as this year's Partner of the Year and look forward to even greater success together in the future."
