Apple suppliers TSMC, Foxconn announce record December revenues as iPhone sales soar
The iPhone's strong holiday sales helped two of Apple's biggest supply chain partners — Taiwan Semiconductor Manufacturing Co. and Hon Hai Precision Industry — post record monthly revenues in December …
Context & Ripple Effects
In January 2015, TSMC and Hon Hai/Foxconn both posted record monthly revenues on the back of holiday iPhone sales — a snapshot of peak iPhone-cycle leverage, when Apple's two biggest hardware partners rose and fell almost entirely with one product line.
The related coverage traces what happened next: Foxconn kept setting quarterly records ($47B in Q1 2021 on 5G device demand), but its growth engine rotated toward cloud products that cushioned a weak-smartphone quarter in 2022 and then AI servers which drove a 20% Q3 2024 jump while consumer electronics, including iPhones, was flat. Meanwhile Apple's China business, $16.1B and up 70% in early 2015, was down 4% YoY to $14.5B by late 2025 — the same supply chain, a decade apart, with different demand drivers.
First-order effects
- TSMC and Foxconn book their strongest month ever directly off iPhone holiday shipments, making their December results a real-time read on Apple unit demand before Apple itself reports.
Second-order effects
- Component and assembly capacity tightens around Apple's ramp, raising the stakes for any competitor trying to secure equivalent foundry and manufacturing slots during the same window.
Third-order effects
- The decade of follow-on coverage shows the structural endpoint: assembly partners deliberately dilute single-customer exposure, with Foxconn's cloud and AI-server businesses eventually outgrowing its consumer-electronics lines.
The trend: Apple's suppliers are migrating from pure iPhone-cycle dependence toward diversified cloud and AI-server revenue, even as each new iPhone launch still produces record months.
