The agentic AI inflection is strengthening storage and optical interconnect momentum; North American hardware chain still requires selective exposure
Citi believes AI data-center demand remains strong, with the clearest preference for NAND/HDD storage, followed by AI-related OEMs and optical interconnect/connectors; weaker PC, smartphone, and automotive demand is the main drag.
- The covered basket is up about 110% year-to-date, substantially outperforming the S&P 500's roughly 10%, led mainly by storage, AI-related hardware OEMs tied to AI deployment/enterprise server refresh, and connectors.
- Citi expects U.S. Big Five hyperscale capex to grow 82% year-over-year in 2026 and 35% year-over-year in 2027, and views AI compute demand as still undersupplied.
- Storage is the highest-conviction theme: AI infrastructure spending is driving NAND/SSD and HDD demand well above supply; NAND has exceptional pricing power and HDD remains in persistent shortage.
- Non-AI end markets are mixed: preliminary 2Q unit shipments for PCs were down 5% year-over-year, and Citi expects 2026 PC unit shipments to decline 15%; smartphone shipments are expected to decline 17% year-over-year in 2026; global auto production has been trimmed to down 2.6%.
- On the short-term view, Citi keeps or adds SNDK, STX, and WDC to the Upside 90-Day Short-Term View, with key catalysts from tight supply-demand, pricing improvement, earnings, and investor days.
Report interpretation
Overview
This report is Citi’s 2Q26 earnings preview for the North America connectors, electronic components, hardware, and storage coverage set. The key conclusion is that the evolution of AI toward agentic AI is shifting infrastructure bottlenecks from pure compute expansion to a tightly coupled compute-storage ecosystem, continuing to support data center, NAND, HDD, eSSD, optical interconnect, and some AI hardware OEM demand. At the same time, non-AI end markets such as PCs, smartphones, and autos are weakening, increasing dispersion across the sector.
Core views
The strongest storyline is AI-driven storage supply-demand tightness: demand for NAND/SSD and HDD is significantly above supply, with hyperscalers prioritized for allocation, while consumer, PC, and channel markets are being crowded out; this creates room for both pricing and margin improvement. The second storyline is network and optical interconnect demand supported by AI capex, benefiting GLW and APH. The third is that AI servers and enterprise infrastructure refresh support hardware OEMs, but customer concentration, order tempo, backlog delivery dynamics, and component-pass-through need close monitoring. The report is clearly cautious on PC, smartphone, and auto demand.
Analysis framework
The report combines the 2Q26 earnings preview, company target price and EPS revisions, end-market demand data, the Citi CIO survey, Big Five capex model, server forecasts, expert interviews, management commentary, and valuation multiples, and then ranks exposures across storage, connectors, optical communications, OEMs, PCs, and autos.
Methodology notes
Agentic AI brings sustained inference, tool interaction, and data persistence, pushing storage demand from training expansion to inference and durable data retention.
The report uses NAND, eSSD, and nearline HDD supply-demand and pricing changes to assess storage vendors’ earnings leverage, emphasizing that current demand exceeds supply while supply growth remains constrained.
Segment demand health across data centers, PCs, smartphones, industrial, autos, connectors, and other end markets.
Data center and industrial are relatively stronger, while PCs, smartphones, and autos are weaker; connector and OEM companies need selective exposure by end-market.
Adjust target prices by forward EPS and P/E multiples.
Target price upgrades for APH, GLW, STX, and WDC mainly reflect stronger earnings expectations and elevated long-term fundamental conviction; the TEL cut reflects lower automotive demand assumptions and compressed valuation multiples.
Potential stock-moving drivers over the next 90 days, including earnings, sector commentary, macro fundamentals, and idiosyncratic events.
SNDK, STX, and WDC are listed as Upside, with catalysts including tight supply-demand, pricing improvement, earnings, the FMS conference, and SNDK investor day.

Impact & implications
The investment implication is to continue positioning AI infrastructure chain as a core theme for North American hardware, but with differentiation across beneficiaries. Storage benefits directly from agentic AI's data generation, duplication, versioning, and KV cache spillover demand, supported by both supply-demand and pricing. Optical interconnect and connectors benefit from AI cluster expansion and rising bandwidth density. AI OEMs benefit from deployment and server refresh cycles, but order tempo, customer concentration, margin ramp, and component-price pass-through risks can weaken transmission. Weak non-AI end markets imply more limited near-term upside in valuation and earnings upgrades for companies with larger exposure to PCs, smartphones, and autos.
Risks
- AI capex and agentic AI infrastructure demand come in below expectations, slowing orders for storage, optical interconnect, and AI servers.
- Storage supply discipline weakens or new capacity ramps faster than expected, eroding NAND and HDD pricing power.
- PC, smartphone, and automotive demand continues to deteriorate, weighing on revenue from related hardware, connectors, and distributor names.
- AI OEMs face risks from customer concentration, order tempo, margin ramp, and component-price pass-through.
- High valuations and crowded positioning could amplify drawdowns if earnings or guidance miss expectations.
- Geopolitics, power infrastructure, supply chain, and memory/chipset shortages could affect costs, delivery, and end-market demand.
