Calix Third Quarter 2026 Earnings Conference Call - CALIX INC

Financial Performance:

• Reported record Q3 2026 revenue of $302 million, representing a 3% sequential increase and 14% year-over-year growth.
• Software and service revenue reached a record $52 million (3% sequential, 19% YoY), driven by subscriber growth and market share gains.
• Non-GAAP gross margin was 53.5%; software and service gross margin hit a record 67.2% (up 340 bps sequentially), while appliance gross margin declined to 50.7% (down 220 bps) due to elevated memory costs.
• Non-GAAP operating expenses were $124 million (41% of revenue), down from 42% the prior quarter, reflecting early productivity gains from AI implementation.
• Remaining Performance Obligations (RPOs) reached a record $396 million (2% sequential, 12% YoY); software/service contracts of one year or less ($6M) were excluded from RPOs to avoid distortion, which would have adjusted sequential growth to 4% and YoY growth to 13%.
• Ended the quarter with $155 million in cash and investments; DSO was 38 days and inventory turnover was 2.8 days.

Guidance and Future Outlook:

• Q4 2026 revenue guidance is set between $311 million and $317 million, reflecting broad deployment of data and border visibility.
• Q4 non-GAAP gross margin guidance is 52.25% to 54.75%, accounting for component cost surcharges and product mix.
• Q4 non-GAAP operating expenses are projected between $129.5 million and $131.5 million; OpEx as a percentage of revenue is expected to drift below 40% as AI-driven productivity increases.
• Q4 non-GAAP EPS guidance is $0.41 to $0.49; full-year 2026 non-GAAP EPS is projected at $1.76, implying 30% EPS growth against 19% revenue growth.
• Long-term annual growth target remains 15%; management anticipates 2027 will see more innovation (1,400 capabilities) than 2025 and 2026 combined, with a flat R&D budget despite increased output.

Business Segments and Product Lines:

• CalixOne contracts signed in Q3 more than doubled from the prior quarter as customers commit to AI strategies.
• Launched Calix Communications Language Model (CLM) and Calix Gems (specialized models) to deliver communication-specific intelligence from cloud to premises.
• Smart Life products are now compatible with "Purple" (on-prem operating system standard for Tier 1s), with full OS Purple certification expected in early 2027.
• SmartMDU product saw major releases with a significant completeness milestone expected in February 2027, targeting broadband, MSPs, and hospitality markets.
• Introduced Workflow Studio for customer customization and released agentic Command IQ and AI Command Center applications.
• Expanded focus to Managed Service Providers (MSPs) serving MDUs and hospitality sectors, moving beyond traditional broadband providers.

Market and Competitive Landscape:

• Market narrative centers on AI as a non-optional necessity; Calix positions itself as the "easy button" for trusted, secure, and cost-predictable AI deployment.
• Case study cited: Allo, a Calix-exclusive partner, achieves 40% lower truck rolls, 60-point higher NPS, and operates with 25 IT staff versus 400.
• Competition in AI is viewed as fragmented and costly; Calix leverages open-weight models to create specialized, low-parameter "Gems" for specific tasks like cybersecurity and Wi-Fi management.
• Management highlights that competitors attempting to build AI in-house face "death and hacking," positioning Calix as the secure, standardized alternative.
• Inventory burn-down continues, but GigaSPire deployment rates are increasing, signaling sustained core demand.

Risks and Challenges:

• Significant supply chain volatility driven by AI data center build-outs, particularly regarding memory component costs, which remain a primary headwind for appliance margins.
• Management forecasts the 2027 cost environment to be "noisy" and potentially more challenging than 2026, with memory prices expected to remain elevated despite hopes for future correction.
• Geopolitical realignments in global supply chains add complexity to cost and logistics management.
• Need to invest in brand awareness for new markets (MSPs, hospitality) where Calix is less known compared to broadband providers.
• Risk of over-investment in AI infrastructure by hyperscalers potentially leading to a future memory glut, though timing is uncertain.

Management Commentary and Tone:

• Tone is highly confident and optimistic, emphasizing a shift from "experimentation to execution" following the Calix Connections event.
• CEO Michael Leaning described the internal R&D productivity jump as "massive," citing a 30-40% increase in output efficiency with a flat 2027 budget.
• Management views the platform transition as complete, declaring the "road forward is really freaking clear" with a focus on "grinding" out execution.
• Strong emphasis on AI as a transformative productivity lever, with leadership teams expected to "agentify" workflows to reduce repetitive tasks.
• CFO Corey Sindelar and CEO Leaning expressed frustration with hyperscalers' capital missteps but confidence that their own margin pressures will eventually reverse as memory prices normalize.

Analyst Questions and Answers:

• Ryan Kuntz (Needham): Asked about RPO mix and software booking trends; Management confirmed a surge in software bookings due to early AI adoption and clarified the $6M exclusion from RPOs.
• George Nodder (Wolff Research): Inquired about appliance unit growth and the "Customer Supply Assurance Program"; Management explained the program as a price-hedging mechanism for customers against memory volatility, ensuring non-cancelable orders in exchange for price certainty.
• Ben Tax (Craig-Hallum): Asked about 2027 growth and margin trajectory; Management reiterated a 15% long-term growth target and noted that while appliance margins face noise, software margins (70% target) are trending up within 2027.
• Joseph Cardozo (JPMorgan): Questioned software margin trends and free cash flow; Management confirmed software margins are heading toward 70% and expects FCF to improve as inventory investments peak and reverse in 2027.
• Scott Searle (Ross Capital): Asked about macro slowdowns and MDU expansion; Management stated decision-making remains robust due to AI urgency, highlighted the rapid ramp of SmartMDU and hospitality segments, and detailed the aggressive productivity gains in R&D.
• Tim Savigo (Northland Capital): Focused on OpEx leverage and memory cost impact; Management confirmed the goal to accelerate OpEx leverage to half revenue growth by 2027 but warned of continued 2027 supply chain noise, estimating appliance margin compression of roughly 500 bps year-to-date.

Other Key Points:

• Stock repurchase authorization increased by $100 million post-quarter, with $44 million remaining from previous balances.
• The CPO of the year award was highlighted as validation of the platform's rapid innovation trajectory.
• Management announced a shift in leadership expectations, requiring all managers to adopt "Six Sigma" workflows to analyze and agentify processes.
• Calix emphasized its role in enabling "predictability of return on investment" for customers, leveraging billions of annual workflows to rank and implement high-value agents.
• The "Customer Supply Assurance Program" has added over $75 million in inventory to the balance sheet over the last 12 months to ensure supply certainty for customers.
