Calix : Letter to Stockholders Q1 2026
CALX

April 21, 2026
Fellow Calix stockholders:
We are issuing this first quarter 2026 stockholder letter just ahead of our earnings call and on the eve of our 2026 Investor Day. With the migration of all customers to our AI-native third-generation platform ("Calix One") by the end of March, we began the third stage of the Calix journey. We look forward to hosting you tomorrow where we will expand on the significance of this milestone.
The year began with strong momentum as our customers continued to invest in the Calix platform to win new subscribers, reduce churn and expand revenue per subscriber. The team also continued its strong execution and progress in helping our customers to transform and win in the markets they serve. Our first quarter 2026 results highlight that strong momentum and execution.
Calix delivered record revenue of $280 million in the first quarter of 2026-our seventh consecutive quarter of growth-representing 3% sequential growth and 27% year-over-year growth. We also guided to continued sequential growth in the second quarter, underscoring sustained platform demand we continue to see from our customers. We added 14 new platform customers, who began their transformation by leveraging our appliances, software, cloud platform and managed services to differentiate their brands within the communities they serve.
Our operational execution remained strong. Days sales outstanding were 36 days; inventory turns were 3.0, reflecting targeted inventory investments to support demand; and we generated free cash flow of
$7 million. During the first quarter of 2026, we returned $171 million to shareholders in the form of share repurchases. Meanwhile, our cash and investments at the end of the first quarter of 2026 remained strong at $243 million.
One of the most significant achievements in the quarter was our launch of Calix One, anchored by Agent Workforce Cloud and SmartLife™. With the migration of all customers to Calix One, customers are now able to take advantage of AI workflows and agents as our product organization pivots from enabling AI on the platform to delivering tangible AI-driven outcomes that transform operations and accelerate differentiation to compete and win. We will highlight these developments at Investor Day tomorrow. This milestone, and our ongoing ability to invest, positions Calix to scale across new customer segments, geographies and use cases while maintaining the financial discipline that has long distinguished our company.
The clarity of our strategy, our commitment to long-term customer transformation, the launch of Calix One and our strong financial foundation continue to position Calix and our customers to benefit from a structural shift in broadband-the commoditization of speed-and-price connectivity and the broader shift that is happening across all industries as the pace of AI-induced change increases. We are ready to execute against these shifts at scale.
With Calix One now live and broadly available, Calix has entered a sustained growth phase that can extend for many years. Continued strong demand visibility reinforces our confidence in this transition.
Building on strong first-quarter execution and the successful launch of our AI-native Calix One platform, the team continued to be recognized for our culture and innovation. In the first quarter of 2026, we earned 14 awards, including:
TMC recognized SmartMDU as "Internet Telephony's Product of the Year"
Glassdoor ranked Calix 88/100 on their "Best Places to Work US" list
Glassdoor ranked Calix 22/25 "Best Places to Work in Tech and AI" list
TMC recognized CommandIQ for "Cybersecurity Excellence"
Comparably ranked Calix 1/100 for "Best Company Outlook"
This quarter's performance reflects our commitment to strengthening the Calix operating model. As industry commoditization advances in 2026, Calix One now integrates AI, cloud, software, managed services and appliances to help customers win subscribers, reduce churn and grow revenue per user. We continue this unified approach to drive better customer outcomes and support sustainable growth as we expand into MDUs, new geographies and private deployments. Our focus remains on delivering long-term results through four clear objectives.
Deliberate revenue growth
Gross margin expansion
Disciplined operating expense investment
Ongoing predictability
We look forward to discussing these priorities in greater detail at our Investor Day tomorrow morning at the New York Stock Exchange. The webcast will begin at 10:00 a.m. ET and will be available on the Calix Investor Relations website.

For the first quarter of 2026, revenue was $280.0 million, representing an increase of 3% from the prior quarter and an increase of 27% compared with the same quarter a year ago. We observed continued strong and broad-based demand from our customers during the quarter.
U.S. revenue was 95% of revenue for the first quarter of 2026 compared to 94% in the prior quarter and down from 96% for the year ago quarter.
U.S. revenue increased 4% sequentially and increased 26% compared with the year ago quarter. International revenue was 5% of revenue in the first quarter of 2026, down 14% sequentially and up 62% compared with the year ago
period. The sequential decrease in international revenue was primarily due to lower shipments to a European customer.
GAAP gross margin for the first quarter of 2026 was 56.9%, a decrease of 80 basis points sequentially and an increase of 120 basis points year-over-year. Excluding stock-based compensation, our non-
GAAP gross margin for the first quarter of 2026 was 57.2%, a decrease of 80 basis points
sequentially and an increase of 100 basis points from the year ago period. The sequential decreases in GAAP and non-GAAP gross margin related to our investment in dual cloud environments to support customer migrations to our third-generation cloud platform (which is now complete). The GAAP and non-GAAP year-over-year gross margin increases relate primarily to continued adoption of our platform by our customers and their winning new subscribers. U.S. tariff and tariff-related costs were not material to first quarter 2026 results.
Software revenue includes AXOS software licenses, which are recognized as delivered, and our SaaS offerings of Calix One (Agent Workforce Cloud and SmartLife™), which are recognized ratably over the service period. Service revenue includes customer success, support and warranty, which are recognized ratably over the service period, and professional services, which are recognized as delivered. Our software enables customers to benefit from the power of data-driven insights and improve their average revenue per user at higher margins with the greatest levels of subscriber satisfaction to drive best-in-class Net Promoter Scores℠. Our SmartLife managed services include: SmartHome™ (which includes Bark, Wi-FiIQ, CommandIQ®, ProtectIQ®, ExperienceIQ® and HomeOfficeIQ™), SmartBiz™, SmartMDU™ and SmartTown®.
During the first quarter of 2026, software and service revenue was $47.1 million, increases of 1% sequentially and 16% compared with the year ago quarter. The smaller sequential growth rate related to fewer days in the first quarter of 2026 relative to the fourth quarter of 2025 (87 days vs. 95 days).
The year-over-year increase related to continued strong demand year-over-year for software licenses, Calix Cloud and SmartLife managed services and to a lesser extent service revenue.
Software and service GAAP gross margin in the first quarter of 2026 was 54.3%, representing a decrease of 590 basis points sequentially and 920 basis points from the year ago period. Excluding stock-based compensation, software and service non-GAAP gross margin for the first
quarter of 2026 was 55.7%, representing a decrease of 560 basis points sequentially and 960 basis points from the year ago period. The sequential and year-over-year decreases related primarily to the transition from our second-generation platform to our third-generation platform during which time we operated in a dual cloud environment to successfully support customer migrations. We substantially completed this transition in the first quarter with no material impacts expected from dual clouds on our future quarterly results.
RPOs result from long-term commitments made by our customers and consist mainly of Calix Cloud, SmartLife managed services, extended warranties and support/maintenance agreements and exclude AXOS software licenses, month-to-month usage-based models and true-ups to actual usage from minimum commitments. These
minimum commitments generally have a three-year term at signing.
At the end of the first quarter of 2026, our RPOs were $376.3 million, a decrease of $8.7 million, or 2%, from the prior quarter and an increase of
$35.9 million, or 11%, from the same quarter a year ago. The sequential decrease in RPOs was due to our focus on migrating customers to our third-generation cloud platform. Our current RPOs were a record $156.7 million, up
$5.2 million, or 3% from the prior quarter and up $28.3 million, or 22%,
from the year-ago quarter. RPOs and current RPOs increased year-over-year due to strong demand for our cloud and managed services model. Our ability to deliver agentic workflows occurred only after customers migrated to our third-generations platform. As such, we expect the growth in RPOs will
accelerate in the second half of 2026 as we begin to deliver agentic workflows and demonstrate the value of Calix One and its ability to transform broadband businesses.
During the first quarter of 2026, appliance revenue, which includes our Access Edge, Experience Edge appliances and related optics, was $232.8 million, an increase of 3% sequentially and 30% compared with the year ago quarter on continued adoption of our platform. Our customers that adopt our
appliance-based platform can quickly pivot toward improving the subscriber experience, thereby enabling them to improve their average revenue per user at higher margins with the greatest levels of subscriber satisfaction.
Appliance GAAP gross margin in the first quarter of 2026 was 57.4%, representing an increase of 20 basis points sequentially and an increase of 340 basis points from the year ago period. Excluding stock-based compensation, appliance non-GAAP
gross margin in the first quarter of 2026 was 57.5%, representing an increase of 10 basis points sequentially and an increase of 330 basis points from the year ago period. The sequential and year-over-year increases relate primarily to the adoption of our platform and growing market share for network and on-premises appliances that are the foundation for the adoption of our software and services.
Our GAAP and non-GAAP operating expenses for the first quarter of 2026 were $146.6 million and
$126.9 million, representing 52% and 45% of revenue, respectively. Sequentially, GAAP operating expenses decreased by $1.4 million primarily due to stock-based compensation, and non-GAAP operating expenses were relatively flat
sequentially but higher than typical for the first quarter due primarily to investments in our agentic platform.
Compared with the year ago quarter, GAAP operating expenses increased by $17.8 million and non-GAAP operating expenses increased by $17.1 million primarily related to increased investments in platform innovation.
Non-GAAP sales and marketing investments were 20% of revenue, which was in-line with our Target Financial Model range of 18% to 20%.
Non-GAAP research and development investments were 30% of gross profit, which is above our Target Financial Model of 29% as we invest in Agent Workforce cloud. Non-GAAP general and administrative investments were 8% of revenue, which is above our Target Financial Model of 7% and was the result of a leadership meeting in January 2026.
Our GAAP net income was $11.2 million for the first quarter of 2026, a sequential increase of $4.0 million and an improvement of $16.0 million from the year ago period. The sequential increase was primarily the result of higher revenue and lower operating expenses and GAAP income taxes. GAAP
net income for the first quarter of 2026 included stock-based compensation of $20.6 million.
Excluding stock-based compensation, our non-GAAP net income was $27.2 million, a decrease of $0.1 million compared with the prior quarter due to higher revenue and gross profit offset by lower interest and other income and higher operating expenses. Non-GAAP net income increased $14.1 million, when compared with net
income of $13.1 million in the year ago quarter due to higher revenue and gross margin.
Our balance sheet remained strong. Our DSO in the first quarter of 2026 was 36 days, up 1 day from the prior quarter and up 6 days from the year ago period, reflecting continued strong shipment linearity. Our Target Financial Model for DSO remains between 35 and 45 days. Inventory turns were 3.0, in-line with the prior quarter and down from 3.6
a year ago. The year-over-year decrease in inventory turns represents investments in inventory to address the robust demand environment and supply chain trends. Inventory turns were within our Target Financial Model of 3 to 4 turns.
Days payable outstanding (DPO) at the end of the first quarter was 37 days, up 11 days from the prior quarter and up 14 days from the year ago quarter. Our Target Financial Model for DPO is
between 25 and 35 days. Our cash conversion cycle was 122 days compared with 131 days in the prior quarter and 109 days in the same quarter last year. Our Target Financial Model for our cash conversion cycle remains between 100 and 130 days.
We ended the first quarter of 2026 with cash and investments of $243.3 million, a sequential decrease of $144.8 million. The decrease was primarily due to our common stock repurchases of 3.3 million shares for $170.9 million and capital expenditures of $8.1 million partially offset by proceeds from
equity-based employee benefit plans of $20.0 million and quarterly operating cash inflows of $14.6 million. We continue to expect both GAAP operating and non-GAAP free cash flow to remain strong due to continued non-GAAP profitability and a robust cash conversion cycle.
The remaining common stock repurchase authorization at the end of the first quarter of 2026 was $63.4 million.

Our guidance for the second quarter of 2026, ending June 27, 2026, reflects our expectations as of the date of this letter.
Our revenue guidance for the second quarter of 2026 is for revenue to be between $287 million and
$293 million, up 4% (at the midpoint) from the prior quarter taking into consideration the robust demand and visibility that we are experiencing across our customer base as well as taking into consideration the revenue impact from assessed surcharges to help partially offset memory component price increases. We expect our annual revenue to grow between 15% and 20% this year.
Our non-GAAP gross margin guidance for the second quarter of 2026 of 55.8% (at the midpoint) is down 140 basis points from the previous quarter. This decline is primarily due the increase in memory component costs and to a lesser extent to customer and product mix partially offset by memory surcharges and the improvement in software and service gross margin after completing customer migrations to the third-generation cloud platform and winding down the second-generation cloud platform. We expect our non-GAAP gross margin to be down by 50 to 150 basis points in 2026, reflecting the impact from memory surcharges, memory component costs not absorbed by surcharges and incremental cloud costs associated with the migration of customers to our latest platform.
Our non-GAAP operating expense guidance for the second quarter of 2026 of $128.0 million (at the midpoint) represents a sequential increase primarily related to accelerating the development of AI functionality and capabilities of our platform, cloud and managed services into the first half of 2026. We expect to return to our Target Financial Model for operating expenses by the fourth quarter of 2026.
We continue to expect our non-GAAP effective tax rate for 2026 will be in a range of 23% to 25%.
The Calix team is excited to enter this next period of growth as customers turn to AI-native Calix One and a partnership with our Customer Success teams to transform operations and accelerate differentiation to compete and win. The third generation of our platform, including Agent Workforce Cloud, SmartMDU and our third-generation mobile app, represents the culmination of 15 years of investment and learning in partnership with our customers.
Our demand visibility is at a near all-time high, and we are pairing that momentum with an AI-enabled internal transformation to evolve how we operate and serve customers. As we build execution readiness to scale Calix One across our base and into new markets, we are embracing new customer segments such as MDU, new sovereign geographies and new private platform customers to compete and win for years to come.
The foundation for our growth continues to be based on three consistent vectors:
With strong demand for the Calix One platform, we are confident in our sequential revenue growth and excited by the multi-year outlook for our business. We appreciate the ongoing support of our customers, employees, partners, vendors, and shareholders, and we are eager to engage in meaningful strategic discussions during tomorrow's investor day.
Sincerely,
Michael Weening, Cory Sindelar,
President and CEO CFO
