Exhibit 99.2

October 24, 2022

Fellow Calix stockholders:

For the third quarter of 2022, the Calix team executed with excellence as we delivered record quarterly revenue despite the ongoing global supply challenge. Moreover, the power of our All Platform model continued to drive strong demand in the form of robust bookings and the continuation of our transformation. Robust bookings combined with supply chain outperformance led to the strong results in the quarter. We are seeing an acceleration in the number of new and legacy communication service providers and investors that are looking to become Calix platform-based Broadband Service Providers (BSPs) to simplify their businesses, excite their subscribers and grow their value for their members/investors and local community. The transformation of the service provider marketplace from builders of “dumb” pipes to providers of a managed experience is gaining momentum and will likely continue for at least the next decade. Our unique platforms – Intelligent Access Edge, Revenue Edge and Calix Cloud – position us perfectly to help this next generation of BSPs succeed.

Our All Platform strategy enables us to focus our investments for the benefit of our BSP customers and their subscribers. Our relentless quarterly cadence of agile innovation yields continuous advancements, which enable our BSP customers to be recognized as the technology and service leaders by their subscribers in their community. Furthermore, our focused product offerings allow us to continue to outperform in a challenging supply environment. Our supply chain team again performed with excellence as we endeavored to meet subscriber demand for our BSP customers’ service offerings. We are beginning to see early signs of supply chain normalization; however, we believe there are at least four quarters of supply unpredictability ahead. We remain resolute in our focus in this difficult environment.

Our mission is to enable our BSP customers to simplify their business, excite their subscribers and grow their value. We continued to make progress on our mission this quarter with an increasing number of BSP customers leveraging the full capabilities of our platforms to grow their businesses. In addition, our platforms and culture continue to be recognized by the technology industry. Our recent awards include:

•Calix Intelligent Access EDGE awarded 2022 Internet Telephony Product of the Year.

•Calix wins multiple Best Workplace Rankings from Fortune, including Best Workplaces for Millennials.

•Calix culture earned multiple Comparably Awards, including Employee Happiness, Work-Life Balance, Compensation and Benefits.

As a broadband cloud and software platform business, we are confident our financial performance improvement will manifest across four measurable objectives over the long term:

•Deliberate revenue growth

•Gross margin expansion

•Disciplined operating expense investment

•Increased predictability

Examples of our progress made in the quarter were:

•Added 26 new BSP customers in the quarter.

•Cloud customer count continued to increase with total Calix Marketing Cloud customers increasing by 28% compared with the year ago quarter.

•Record quarter for the EXOS platform with revenue up 81% compared with the year ago quarter as both new and existing customers continue to accelerate deployments of the Revenue EDGE solution.

•Record quarter for the AXOS platform with revenue increasing by 118% compared with the year ago quarter driven by the technology upgrade cycle to XGS PON.

Our near-term focus remains on serving the needs of our BSP customers, while our long-term focus remains on identifying strategically aligned service providers, regardless of their type, size or location, that are ready to transform and partners that are ready to integrate with our platforms to speed the success of our BSP customers. Furthermore, we remain committed to aligning our investments to our mission, vision and strategy while maintaining strong discipline over our operating expenses. Over the long term, we believe this focus will drive continued improvement in our financial performance.

Demand remained robust throughout the third quarter of 2022, and our supply chain team outperformed expectations despite the continued challenging global environment for component sourcing and supply chain logistics. Total revenue was above the high end of our guidance and increased 37% compared with the year ago quarter. Systems revenue for the third quarter of 2022 increased 38% compared with the year ago quarter with continued strong demand for our All Platform offerings as service providers continue to respond to higher subscriber demand for improved and next-generation services and supply becoming less constrained. Compared with the prior quarter, systems revenue increased 18% as our supply chain team was able to pull forward deliveries, which led to an increase in inventory as well. Services revenue increased 15% compared with the year ago quarter due to the continued ramp of our next generation services. Compared with the prior quarter, services revenue decreased 3%. We continue to align our services business with our All Platform model through the introduction of higher differentiated-value services. With the filing of our Form 10-K in 2023, we will no longer breakout services revenue.

Revenue from small customers was 79% of total revenue in the third quarter of 2022 and down from 86% in the year ago period, but increased 26% in absolute dollars due to higher demand for our All Platform offerings. This helped offset decreased purchases of our legacy systems. Revenue from medium-sized customers was 14% of total revenue in the third quarter of 2022 and up from 8% in the year ago period, and increased 136% in absolute dollars, reflecting significant shipments to a new medium customer and increased investments by many of the existing medium customers. Revenue from large customers was 7% of total revenue in the third quarter of 2022 and up from 6% in the year ago period, and increased 59% in absolute dollars, primarily due to greater shipments to two customers. We continue to focus on finding strategically aligned customers of all types and sizes for our All Platform offerings.

U.S. revenue was 91% of total revenue in the third quarter of 2022 and increased 58% compared with the year ago quarter and increased 17% sequentially. This increase is primarily due to continued sales and marketing investments in the U.S. to address the significant opportunity ahead. International revenue was 9% of total revenue in the third quarter and decreased 43% compared with the year ago quarter primarily due to lower shipments to a European customer and increased sequentially 13% due to increased shipments to a European customer partially offset by lower shipments to the Middle East and Africa.

Remaining performance obligations, or RPOs, result from long-term commitments made by our customers and consist mainly of Calix cloud, extended-warranty, IQ suites and support agreements. These commitments generally have an initial term of three years. At the end of the third quarter, our RPOs were $173.1 million, which is an increase of $68.1 million, or 65%, from the year ago period. The increase reflects the higher adoption of our All Platform offerings by an increasing number of our BSP customers. Compared with the prior quarter, RPOs increased $10.3 million, or 6%, which reflects the inherent lumpiness in the contracting business.

Supply chain challenges continue to impact our GAAP and non-GAAP gross margin. While we achieved another quarter of growth in our All Platform offerings, this positive trend was offset by significantly higher component and logistics costs in the quarter. Specifically, GAAP gross margin decreased 190 basis points year over year to 50.1%, and non-GAAP gross margin decreased 150 basis points to 50.7%. On a GAAP basis, systems gross margin decreased 220 basis points to 51.0% compared with the year ago quarter due to higher component and logistics costs and increased 40 basis points sequentially primarily due to product mix. On a non-GAAP basis, systems gross margin of 51.5% decreased 180 basis points

4

year-over-year due to higher component and logistics costs, which more than offset the benefit from continued growth in our All Platform offerings as a percent of revenue. Sequentially, systems gross margin on a non-GAAP basis increased 50 basis points due mainly to product mix. This represents the first sequential increase in gross margin in six quarters. Compared with the year ago quarter, services gross margin on a GAAP and non-GAAP basis increased 140 and 200 basis points, respectively, primarily due to the continued ramp of services in support of our All Platform offerings. Sequentially, services gross margin on a GAAP basis decreased 20 basis points due to increased stock-based compensation and on a non-GAAP basis increased 20 basis points due to higher revenue and the continued ramp of our next generation services. As stated earlier, with the filing of our Form 10-K in 2023, we will no longer breakout services revenue, and thus we will no longer breakout services gross margin at the same time.

Compared with the year ago quarter, GAAP and non-GAAP operating expenses increased by 38% and 35%, respectively, primarily due to headcount increases in sales and marketing, a higher level of investments in research and development programs and continued investments in our IT systems. These investments are needed to support the current and future demand for our All Platform offering. Sequentially, GAAP and non-GAAP operating expenses increased by 9% primarily due to increased headcount.

Non-GAAP operating expenses were slightly above the high-end of our guidance range primarily due to higher headcount during the quarter and increased incentive compensation given the revenue overperformance. Our investments relative to our non-GAAP target financial model fell short this quarter due to the significant revenue overperformance. Specifically, sales and marketing investments were 18% of revenue, which is at the mid-point of our target financial model range of 17% to 19% versus our desired level of 19%. Research and development investments were 26% of systems gross profit, which is short to our target financial model of 30%. General and administrative investments were 6% of revenue, below our target financial model of 8%. We expect to maintain our operating expense discipline and align our investments with our target financial model to capitalize on this multi-year opportunity.

5

On a GAAP basis, our net income of $13.4 million for the third quarter of 2022 decreased $164.0 million year-over-year. The unusually high GAAP net income in the third quarter last year was due primarily to the reversal of a substantial portion of the valuation allowance against our deferred tax assets in the year ago period. The release and other charges amounted to $160.2 million and are excluded from our non-GAAP net income. Compared with the prior quarter, our GAAP net income increased by $5.9 million primarily because of higher revenue at slightly elevated gross margin. Our GAAP net income for the third quarter of 2022 included stock-based compensation of $11.0 million and intangible asset amortization of $0.7 million partially offset by the income tax effect of these items of $1.4 million. Compared with the year ago period, our non-GAAP net income for the third quarter of 2022 decreased $0.1 million to a net income of $23.8 million from a net income of $23.9 million primarily due to higher income taxes of $8.4 million as we began providing for income taxes in 2022 as our valuation allowance reversed in the third quarter of 2021 nearly offset by growth in revenue, resulting in increased operating income. Compared with the prior quarter, our non-GAAP net income increased $9.0 million to $23.8 million from $14.8 million. This increase is the result of the revenue overperformance at a slightly higher gross margin and our inability to react within the quarter and invest to our target financial model.

Balance Sheet and Cash Flow

We ended the quarter with record cash and investments of $234.7 million, a sequential increase of $9.8 million. The increase was primarily the result of the proceeds from equity-based employee benefit plans of $7.0 million and positive non-GAAP free cash flow of $3.3 million. We continued to generate positive

6

operating and non-GAAP free cash flow and expect this trend will continue. Due to the challenging supply chain environment, our inventory remains elevated to improve our responsiveness to customer demand. Compared with the year ago quarter, our cash and investments increased by $46.0 million primarily due to positive free cash flow of $21.2 million and proceeds from equity-based employee benefit plans of $28.4 million.

Our team remains focused on operational excellence and customer satisfaction. During the third quarter of 2022, our supply chain team exceeded our expectations despite the continued challenges in component supply and logistics. While port congestion improved, costs remain elevated, lead times remain extended and de-commits, while diminishing, were still a challenge. Despite these headwinds, we saw a pull forward of deliveries, leading to our third quarter revenue over performance and the buildup of inventory at quarter end. Our days sales outstanding (DSO) at quarter end was 39 days, which was the same as the prior quarter and 10 days lower than the prior year, reflecting shipment linearity during the quarter despite ongoing supply chain disruptions. Our target financial model for DSO remains between 35 and 45 days. Inventory turns were 3.1 at quarter end, down slightly from the prior quarter’s 3.5 turns and down from 3.8 turns in the year ago quarter. This aligns with our target financial model for inventory turns to be between 3 and 4 to better support the needs of our customers. The year-over-year and sequential decreases in inventory turns in the quarter were the result of a higher level of inventory. Days payable outstanding (DPO) at quarter end was 39 days, up 17 days from the prior quarter and up 2 days from the year ago quarter. Our target financial model for DPO is to be between 25 and 35 days. Our cash conversion cycle was 117 days compared with 122 days in the prior quarter mostly due to higher DPO partially offset by inventory turns. Compared with the year ago quarter, our cash conversion cycle increased 9 days as the increase in inventory turns more than offset the lower DSO. Our target financial model remains for our cash conversion cycle to be between 100 and 130 days. We continue to believe our existing cash and investments and expected positive non-GAAP free cash flow will provide us with sufficient liquidity for our business.

Fourth Quarter 2022 Guidance

2	Based on 69.6 million weighted-average diluted common shares outstanding.

Our guidance for the fourth quarter of 2022 ending December 31, 2022, reflects our expectations as of the date of this letter. These expectations reflect our current inventory level and assessment of supply chain and logistical challenges.

Our revenue guidance for the fourth quarter of 2022 at the mid-point is for a sequential increase of 2% and a year-over-year increase of approximately 36%. At the mid-point of our guidance, annual revenue would represent a 27% year-over-year increase.

Our non-GAAP gross margin guidance for the fourth quarter of 2022 at the mid-point represents a decrease of approximately 80 basis points relative to the year ago quarter. This reflects expectations of product mix and higher component and logistics costs partially offset by a positive benefit from the continued increase of our All Platform offerings as a percent of total revenue. Non-GAAP gross margin continues to be burdened by increasing costs for components and logistics that will continue to flow through inventory for the foreseeable future. We continue to expect the increase in our All Platform offerings as a percent of total revenue to positively benefit non-GAAP gross margin by 100 to 200 basis points per year starting next year.

Summary

Every day the magnitude of the opportunity becomes clearer while at the same time growing ever larger. Our relentless focus on seizing this opportunity begins with helping our customers succeed by enabling them to simplify, excite and grow.

Our All Platform software, cloud, associated systems and services offerings have enabled us to build our ecosystem to speed our customers’ success. On September 30th, we took the next step in our evolution by promoting Michael to President and Chief Executive Officer. Michael’s deep experience in customer success as an operating strategy, software, cloud, platform and ecosystem businesses, allied with his six-year tenure at Calix, has prepared him well to lead us forward. Carl will remain Chairman of the Board and continue to guide and oversee this next phase of our evolution.

We remain in the early stages of an enormous secular opportunity, and our focus on executing the fundamentals of our strategy to capture this opportunity will bring value to our customers, their subscribers, our employees and our stockholders. We sincerely thank our employees, customers, partners, vendors and stockholders for their continued support as we pursue our future.

Sincerely,

Carl Russo Chairman Michael Weening President and CEO     Cory Sindelar CFO
