Nokia (NOK) Q1 2026 earnings review
AI Supercycle Ignites Optical Growth, Masking Telco Weakness
Nokia delivered a strong Q1 2026, validating its strategic pivot toward data center infrastructure. Comparable net sales grew 4% in constant currency to EUR 4.5B, while comparable operating margin expanded 200 bps to 6.2%. The headline story is the massive 49% growth in AI & Cloud customer sales, which drove Optical Networks revenue up 20%. This robust momentum, backed by EUR 1B in new AI/Cloud orders, prompted management to significantly raise the Network Infrastructure full-year growth outlook to 12-14%. However, the traditional telco business remains a drag, with Telecommunication Provider sales down 2% and Fixed Networks contracting 13%. Overall, earnings quality is improving as the company successfully replaces lower-margin legacy business with hyper-growth AI infrastructure contracts.
🐂 Bull Case
Nokia booked EUR 1B in AI & Cloud orders in Q1 alone. Management raised the addressable market CAGR for this segment from 16% to 27%, indicating massive, multi-year tailwinds.
Comparable gross margin jumped 320 bps to 45.5%. This was driven by Infinera integration synergies, favorable software mix, and aggressive cost discipline.
🐻 Bear Case
Telecommunication Provider sales fell 2%, keeping Radio Networks revenue completely flat. The legacy customer base is still compressing.
Fixed Networks sales dropped 13% as the company shifts away from consumer fiber products, temporarily bleeding revenue from the Network Infrastructure segment.
⚖️ Verdict: 🟢
Bullish. Nokia is successfully transitioning from a stagnant traditional telco supplier to a critical player in the AI/data center infrastructure buildout. The raised guidance in Network Infrastructure signals excellent forward visibility.
Key Themes
AI & Cloud Supercycle Pulls Network Infrastructure Forward
AI & Cloud sales grew 49% in Q1 and now account for 8% of total group sales. This direct exposure to hyperscaler data center buildouts drove a 20% surge in Optical Networks and allowed management to confidently revise the 2025-2028 addressable market CAGR for AI/Cloud from 16% up to 27%.
Infinera Integration and DSP Innovation
Technological innovation is accelerating. At the OFC conference, Nokia launched 4 new Digital Signal Processors (DSPs) that power 13 new application-optimized solutions (including Ontario, Huron, Superior, and Pacific platforms). These innovations reduce Total Cost of Ownership (TCO) by up to 70% for customers. Coupled with Infinera synergies, this vertical integration is a primary driver behind the 320 bps group gross margin expansion.
Mobile Infrastructure Margin Recovery
Despite flat revenues in Radio Networks, the Mobile Infrastructure segment's operating margin skyrocketed from 5.1% in 25Q1 to 8.9% in 26Q1 (+380 bps). This was achieved through stringent cost discipline, a 5% growth in high-margin Core Software, and the absence of a prior-year one-time contract settlement charge.
Telecommunication Provider Weakness Contradicts Boom Narrative
While the headline growth is positive, a critical data point contradicts the 'supercycle' narrative for the broader company: sales to 'Telecommunication Providers' (Nokia's largest historical customer base) fell 2% in constant currency to EUR 3.27B. The company's overall growth is currently entirely reliant on the smaller EUR 350M AI & Cloud segment scaling fast enough to offset the decay in this massive legacy base.
Fixed Networks Contraction
Fixed Networks was the clear laggard, with sales dropping 13% in constant currency. Management attributes this to a deliberate strategic shift away from lower-margin consumer premise fiber products toward higher-margin operator premise terminals. Until this transition completes, it acts as a severe drag on the Network Infrastructure division's top line.
Extending Supply Chain Lead Times (Macro)
Management explicitly warned of macro supply chain pressures, noting that 'demand is accelerating and lead times are extending' due to the sheer scale of global AI investment. If Nokia's new San Jose indium phosphide manufacturing facility (ramping later this year) faces delays, the company risks leaving highly lucrative Optical Network revenue on the table during this critical land-grab phase.
Other KPIs
Reversing. FCF was exceptionally strong, rebounding significantly from weaker historical first quarters. This was primarily driven by a EUR 400M net working capital inflow (largely due to a EUR 220M decrease in receivables). Management reiterated their full-year FCF conversion target of 55% to 75%.
Accelerating. Net cash and interest-bearing financial investments increased 27% YoY from EUR 2.99 billion in 25Q1. This provides Nokia with a formidable balance sheet to sustain its aggressive R&D investments, dividend payments (EUR 0.04/share declared), and potential M&A.
Stable to Accelerating. R&D spending increased 3% YoY on a comparable basis, reflecting targeted investments to capture accelerating demand in AI & Cloud and Optical Networks, while SG&A expenses were kept under tighter control (+4%).
Guidance
Stable. The official guidance range was maintained, but management provided a bullish caveat, stating they are 'currently tracking somewhat above the mid-point' of this outlook due to outperformance in Optical Networks.
Accelerating. This is a massive upward revision from the previous assumption of 6% - 8% growth. The upgrade is entirely driven by demand acceleration in AI & Cloud and increased supply visibility.
Accelerating. Upgraded drastically from the previous 10% - 12% expectation. This sub-segment is the primary beneficiary of hyperscaler data center interconnect spending.
Key Questions
Supply Chain Constraints vs Target Upgrades
You noted that macro lead times are extending across the supply chain. What specific supply guarantees or internal manufacturing milestones (e.g., the San Jose facility ramp) give you the confidence to radically upgrade Optical/IP growth guidance to 18-20% despite these bottlenecks?
Telecommunication Provider Stabilization
Sales to Telecommunication Providers declined 2% in constant currency. Do you see this legacy customer segment finding an absolute floor in H2 2026, or should we model structural, low-single-digit declines indefinitely?
Fixed Networks Revenue Bridge
Fixed Networks contracted 13% due to your strategic shift away from consumer premise fiber. In what quarter do you expect the growth in higher-margin operator premise terminals to finally overtake the consumer drag and return this unit to absolute revenue growth?
