Exhibit 99.2
calixlogo8ka232.jpg
July 21, 2020

Fellow Calix stockholders:

As the coronavirus has continued to spread around the world, the future remains uncertain. Without a vaccine, and with scant treatments available, no one knows how or when this terrible crisis will end. The escalating human cost and the massive changes in society we discussed last quarter have continued into this quarter … and will likely do so into the foreseeable future. It is critical all of us remain connected, and that is our mission.

There are two secular disruptions moving through the communications industry, and we are perfectly positioned to ride both. The pandemic is accelerating these disruptions as our lives have changed in almost every way from what they were just a little more than a quarter ago. Given more activity taking place at home on digital and social platforms, we have already seen, and are likely to continue to see, greater strain on service provider broadband networks across the globe. This in turn requires service providers to respond by increasing capacity on their networks to handle the higher data traffic. We have seen both effects driving demand for our products. The larger portion of the current demand is a pull forward to meet capacity, with the smaller effect being an acceleration of our All Platform business. For many, this response is clearly pulling forward capital investments that would have occurred in future periods be they quarters or even years. However, for innovative service providers, the pandemic presents an opportunity to seek better tools to do this most expeditiously and cost effectively. Insights and analytics available in Calix Cloud and tools inside EXOS and AXOS fit perfectly within this new normal as they enable service providers to reduce network complexity, decrease subscriber churn due to service outages and dramatically shrink network issue resolution time.
As a company, we remain focused on the health and welfare of our employees and their families. In our view, only by remaining healthy and strong can we continue to serve the needs of our customers. As we noted last quarter, we have been building a virtual culture for many years, and we accelerated our shift to an all-virtual mode, which remains in effect today. We have now made the decision to embrace a Work-From-Anywhere culture, and this operating mode dramatically reduces our physical facilities requirements. Furthermore, our customers are accelerating their interest in our All Platform offerings, and we took actions in the second quarter to align our product portfolio to this acceleration. Our second quarter financials reflect the impact of these actions as GAAP charges to our operating results.

With service providers of all types responding to the increased demand for their services, the value of our all platform offerings continues to resonate, and demand for our platforms continues to grow. With many of our customers still playing catch up to the surge in bandwidth usage on their networks continuing from what we discussed last quarter, we had a strong quarter with reported results above the high end of our guidance for revenue, non-GAAP gross margin, non-GAAP operating expenses and non-GAAP net income per diluted common share. In addition, for the fourth consecutive quarter, we generated positive operating cash flow. Despite highly limited in-person interaction during the quarter, we expanded our addressable market again this quarter as we added 18 new customers. As has been the trend over the past quarters, most of these new customers came from emerging customer verticals. This continued expansion of our customer base is fundamental to our transformation and creates a foundation for predictable, profitable growth for years to come.

Riding the Wave of Disruption

Our vision is focused on providing the platforms and services that enable innovative service providers to create services at a DevOps pace and provide their subscribers with an exceptional experience.

Service providers achieve this objective by building their infrastructure and service offerings on platforms. The ongoing wave of disruption sweeping across the communications space remains unprecedented in our experience. We continue to see traditional business models being disrupted as service providers of all types learn to adapt to the demands of the device-enabled subscriber. As the market continues to disrupt, the gap between subscriber needs and service provider supply continues to grow. New service providers are being created to address this unmet need, and capital is being formed to support them. We see this investment accelerating in the market, and it is well aligned with our mission; and we see the pace of existing service providers transforming to address this need hastening as well. As these service providers realign their investments, we are finding areas where our platforms can help them grow. In short, when a service provider of any type chooses to own the subscriber experience, we are well positioned to help them succeed.

Continued Transformation to an All Platform Company

Our relentless focus on the transformation of Calix into a communications cloud and software platform business yielded further progress in the second quarter of 2020. As we stated in our prior letters to stockholders, we continue to believe this transformation will manifest in improved financial performance across four measurable metrics over the long term:

Deliberate revenue growth
Gross margin expansion
Disciplined operating expense investment
Increased predictability

In the second quarter of 2020, we made solid progress on all these metrics, and we expect these metrics will continue to improve as our platforms increase as a percentage of our total business. Examples of our progress made in the quarter were:

Added 18 new customers in the quarter from all segments of the market.
Customers continue to recognize the power of data and analytics with Calix Cloud revenue increasing by more than 60% compared to the year ago quarter.
Record quarter for the EXOS platform with systems shipments up more than 60% year-over-year and revenue up more than three-fold as customers increasingly decide to implement the Revenue EDGE solution to deliver a superior broadband experience for their subscribers.
AXOS platform shipments increased by more than 70% compared to the year ago quarter as customers strive to increase bandwidth on their networks.
As customers increasingly implement the Revenue Edge solution, we saw an eight-fold year-over-year increase in customers choosing to utilize the CommandIQTM personalization service enabling customers to elevate both their brand and their subscriber’s broadband experience.

Our near-term focus is on serving the needs of our service provider customers, while our long-term focus remains on finding like-minded customers regardless of their type, size or location. Furthermore, we remain committed to aligning our investments to our strategy and maintaining strong discipline over our operating expenses. Over the long term, we believe this focus will drive continuous improvement in our financial performance.

Overall results for the second quarter of 2020 were well above our financial guidance for the quarter as overall demand was robust and our supply chain outperformed despite the continued challenging global environment for component sourcing. Total revenue was above the high end of our guidance range, increasing 19% compared to the year-ago quarter. This strong performance was driven by demand for our platforms and the continued ramp of new offerings with the majority of growth coming from our small customer base. Non-GAAP gross margin was above the high-end of our guidance owing to improved product and customer mix. Meanwhile, our non-GAAP operating expenses undergrew revenue and were just above the high end of our guidance range due to our continued focus on maintaining financial discipline and higher incentive compensation due to the increased profitability in the second quarter, partially offset by a temporary benefit from reduced travel-related expenses. All of this resulted in earnings well above our guidance. Finally, our continuing focus on balance sheet discipline resulted in our fourth consecutive quarter of positive operating cash flow generation.

Systems revenue for the second quarter of 2020 increased 19% compared to the year ago quarter on strong demand for our Calix Cloud, EXOS and AXOS platforms along with near-term demand for our legacy systems as service providers respond to increased demand on their networks. Compared to the prior quarter, systems revenue increased 17%, which was above normal seasonality as service providers accelerated some deployments to relieve network capacity constraints. Services revenue increased 10% compared to the year ago quarter as the continued ramp in our next generation service offerings offset lower professional services related to CAF deployments. Compared to the prior quarter, services increased by 14% due to new program ramps. We continue to align our services business with our All-Platform model through the introduction of higher differentiated-value services.

Domestic revenue was 91% of total revenue in the second quarter and increased 26% compared to the year ago quarter due to strong demand for our platforms. International revenue was 9% of total revenue in the second quarter and declined 25% compared to the year ago quarter.
a2revcust1.jpg
Revenue from large customers was 21% of total revenue in the second quarter of 2020 and increased by 27% compared to the year ago quarter primarily due to greater shipments to Verizon and CenturyLink. CenturyLink was our only greater than 10% of revenue customer in the quarter at 15%. Revenue from medium-sized customers was 7% of total revenue in the second quarter of 2020 and increased 14% compared to the year ago quarter reflecting the initial quarter of shipments to a new medium-size customer along with increased demand among a small subset of customers. Revenue from small customers was 72% of total revenue in the second quarter of 2020 and increased 17% as compared to the year ago quarter due to strength in demand for Calix Cloud, EXOS and AXOS platforms along with increased demand for our legacy systems. We will continue to focus on finding strategically aligned customers of all types and sizes for our all-platform business.
a3gm1.jpg
Driven by favorable product and customer mix, both GAAP and non-GAAP gross margin, increased in the second quarter of 2020 relative to the year-ago quarter. Specifically, GAAP gross margin increased 290 basis points year over year and non-GAAP gross margin increased 360 basis points year over year. Our GAAP gross margin included a component inventory accrual of $1.8 million (or 151 basis points) related to our reduction and consolidation of legacy product lines. On a GAAP basis, including the above-mentioned charge, systems gross margin increased 290 basis points compared to the year ago quarter due to favorable product and customer mix along with lower U.S. tariff and tariff-related costs. In the second quarter of 2020, U.S. tariff and tariff-related costs and intangible asset amortization costs were 125 basis points of systems gross margin compared to 200 basis points in the year ago quarter, and the component inventory accrual was 162 basis points of systems gross margin. On a non-GAAP basis, systems gross margin of 51.8% reflects increases of approximately 310 basis points year-over-year and 360 basis points sequentially. The principal drivers of both the year-over-year and sequential increase in non-GAAP systems gross margin were continued growth in our All-Platform offerings along with favorable product and customer mix. On a GAAP basis, services gross margin increased by 920 basis points compared to the year ago quarter primarily due to improved mix towards our higher gross margin support services versus lower gross margin deployment services. Sequentially,

on a GAAP basis, services gross margin increased by 250 basis points again due to a higher mix of support services as compared to deployment services.
a4opex1.jpg
Operating expenses on a GAAP basis increased compared to the prior quarter and the year ago quarter primarily due to restructuring charges of $6.3 million. During the second quarter of 2020, we realigned our real estate portfolio to better balance our future needs as many of our employees have elected to work remotely on a permanent basis, and as a result, we recorded a facilities-related restructuring charge of $5.1 million. In addition, we took actions to further our All-Platform model, resulting in severance-related restructuring charges of $1.2 million. On a non-GAAP basis, operating expenses in the second quarter increased 7% year over year due to sales and marketing investments, higher incentive compensation and a provision for bad debt. Meanwhile, non-GAAP operating expenses increased 3% sequentially, while revenue increased by 17%, as short-term reductions in travel and entertainment expenses were offset by greater than expected incentive compensation and a provision for bad debt. As demonstrated this quarter, we expect to maintain our operating expense leverage while maintaining our pace of innovation.
a5ni1.jpg
We reported a net profit on a non-GAAP basis in the second quarter of 2020. On a GAAP basis our net loss decreased by $0.8 million year-over-year, including restructuring charges of $6.3 million and a component inventory accrual of $1.8 million, from a loss of $5.0 million to a loss of $4.2 million. Our GAAP net loss for the second quarter of 2020 included restructuring charges of $6.3 million, stock-based compensation of $3.2 million, a component inventory accrual of $1.8 million, U.S. tariff and tariff-related costs of $0.7 million and intangible asset amortization of $0.7 million. With the increased revenue and higher gross margin compared with the year ago quarter, our non-GAAP profitability for the second quarter of 2020 improved by $9.1 million from a net loss of $0.6 million to a net income of $8.5 million.

Balance Sheet and Cash Flow
a6opcf1.jpg
We ended the second quarter of 2020 with cash of $50.6 million, a sequential increase of $4.4 million. The sequential increase in our cash was primarily the result of positive operating cash flow of $2.7 million and proceeds from equity-based employee benefit plans of $9.2 million partially offset by lower borrowing of $4.0 million on our line of credit and capital expenditures of $2.8 million. Operating cash flow increased sequentially despite our previously disclosed inventory investment in order to improve our responsiveness to customer needs as shipment and billing linearity was improved relative to the prior quarter. Compared to the year ago quarter, our cash increased by $15.6 million primarily due to positive operating cash flow of $11.8 million and proceeds from equity-based employee benefit plans of $14.7 million partially offset by capital expenditures of $8.3 million, lower borrowing of $4.0 million on our line of credit and payments under financing arrangements of $2.8 million.
a7cashconv1.jpg
Our team remains focused on operational excellence and customer satisfaction. During the second quarter of 2020, our supply chain team performed well to meet customer needs despite continued component supply challenges caused by the coronavirus pandemic as we continue to qualify new suppliers and incur expediting costs. With our Oracle ERP transition behind us, our days sales outstanding (DSO) at quarter end returned to a more normalized level and was 45 days, down 13 days from the prior quarter and down 10 days from the prior year. Inventory turns were 5.9 at quarter end, compared to 5.2 turns in the prior quarter and 3.8 turns in the year ago quarter. The higher inventory turns in the quarter were the result of a higher level of revenue. We expect to further add to our inventory in the third quarter of 2020 to improve our ability to respond to customer needs. Days payable outstanding at quarter end was 12 days, down 23 days from the prior quarter and down 47 days from the year ago quarter. Our cash conversion cycle increased slightly to 94 days compared to 93 days in the prior quarter as the decrease in days payable outstanding offset the improvement in DSO and inventory turns. Compared to the year ago quarter, our cash conversion cycle increased by 4 days from 90 days.

We continue to believe our existing cash, expected positive operating cash flow and line of credit will provide us sufficient liquidity for our business operations while navigating the uncertainty created by the coronavirus pandemic.

Our non-GAAP gross margin guidance for the third quarter of 2020 reflects continued growth of our platform offerings as well as favorable customer, product and regional mix, offset by a sequential increase in expediting costs as we continue to face component supply limitations.

Our non-GAAP operating expense guidance for the third quarter of 2020 reflects planned investments in sales and marketing along with a modest increase in travel and entertainment expenses. Consistent with past quarters, we remain focused on operating expense investment discipline.
Finally, we expect positive free cash flow next quarter reflecting expected GAAP and non-GAAP profitability and continued focus on working capital velocity.

Summary

We are proud of our team as we focused on executing on behalf of our customers. Strong demand for our platforms along with the rapid expansion of our customer base continues to demonstrate the progress we made towards our mission in the second quarter. As we remain focused on executing on our market opportunity and supporting our customers, we expect to see our financial performance continue to improve as we drive toward our target financial model starting in 2021.

In the second quarter of 2020, we capitalized on a strong demand environment as our customers continued to respond to the increased demand for broadband. We demonstrated solid revenue growth, increased gross margin, disciplined operating expense investments and generated positive operating cash flow for the fourth consecutive quarter. Based on a strong backlog exiting the quarter and a solid pipeline of opportunities for our platforms, we are excited to project another quarter of double-digit year-over-year revenue growth, improved profitability and continued positive operating cash flow.

We see many innovative service providers looking to Calix to provide the solutions and services to enable them to improve their subscribers’ experience, thereby driving their revenue higher, lowering their churn and increasing their return on investment. With an expanding pipeline of opportunities spanning service providers of every type, we believe we are well placed to continue building Calix … an all platform company … that is positioned in front of two substantial disruptions for service providers impacting network architecture and business models. We remain committed to our vision, and we sincerely thank our employees, customers and stockholders for their continued support as we capitalize on this opportunity.

Sincerely,
