[Foxconn](https://theinference.org/markets/companies/foxconn-hon-hai-precision-industry), formally Hon Hai Precision Industry, said cloud and networking gear, the segment that assembles AI servers, [passed smartphones as its biggest source of revenue](https://asia.nikkei.com/spotlight/supply-chain/taiwan-s-foxconn-has-strong-confidence-in-2027-due-to-ai-demand) [1][4]. The segment took 54 percent of third-quarter sales, up from 51 percent the quarter before [1]. The quarter that made the flip official also produced a record profit of NT$77.5 billion (US$2.4 billion), ahead of the NT$70.3 billion analysts expected [2]. Chairman Young Liu says [capacity is booked for at least 18 months](https://theinference.org/article/foxconn-s-october-revenue-jumped-46-with-capacity-booked-18-months-out-texas-permits-are-the-new-risk), with [AI rack shipments guided to high double-digit growth again this quarter](https://cryptobriefing.com/foxconn-ai-server-rack-shipments-q4/) [1]. Orders are booked, which settles the demand question and leaves margin as the open one. *Chart: **Server gear is swallowing the assemblers' revenue mix** Column chart comparing share of revenue from server gear: Foxconn cloud and networking 51 percent in Q2 and 54 percent in Q3 2026; Quanta servers above 80 percent in Q3 and guided 85 to 90 percent for 2027.* *Each company's own segment disclosure: Foxconn cloud and networking, Quanta servers. The Quanta 2027 figure is company guidance. [1][6]* ## Operating profit outran revenue, which answers the pass-through charge The bear case treats Foxconn as plumbing: [Nvidia](https://theinference.org/markets/companies/nvidia)-linked volume passed through at thin assembler margins. The income statement now argues back. Gross margin narrowed to 6.02 percent [3]. [Operating income still grew 64 percent, faster than revenue](https://www.securities.io/foxconn-q3-operating-profit-rises-64-as-revenue-grows-46/), on better product mix and scale, and net profit lagged only because non-operating items collapsed [3]. Scale is converting into core profit, not just into sales. *Chart: **Foxconn's operating income grew faster than revenue last quarter** Bar chart of Foxconn's third-quarter 2026 year-on-year growth: revenue 46 percent, operating income 64 percent, net profit 34 percent.* *Year-on-year growth for the July to September 2026 quarter, in New Taiwan dollars. Source: Foxconn quarterly results, via Securities.io. [3]* The cash statement is the qualification. The first nine months consumed NT$287 billion of free cash as capex and receivables grew [3]. Foxconn is financing part of the AI buildout from its own working capital, and that line decides how durable the margin story is. ## Supply, not demand, is the bottleneck now Liu expects demand to keep outpacing supply into next year, with tight conditions persisting [2], and names component shortages, geopolitics, inflation and monetary policy as the 2027 risks [4]. The buildout runs from Nvidia's chips through racks to the electricity feeding data centers, and the constraint has moved from orders to parts and power: [DIGITIMES](https://www.digitimes.com/news/a20261112PD243/quanta-2027-capex-ai-server-revenue.html) reports that [Quanta](https://theinference.org/markets/companies/quanta-computer), the other big rack maker, is shifting its 2027 capex toward power [5]. [Quanta more than doubled revenue the same week on a gross margin of 4.75 percent](https://cryptobriefing.com/quanta-computer-record-revenue-ai-servers-margin/) [6]. That is where next year's winners get decided. ## Shares are up 4 percent while Taiwan's index gained 49 [Foxconn builds roughly 40 percent of the world's AI servers](https://theinference.org/article/foxconn-nvidia-s-biggest-ai-server-maker-grew-october-revenue-45-7-but-its-ai-segment-slipped) and aims for half [1], yet [its shares are up 4 percent this year](https://www.msn.com/en-us/news/other/taiwans-foxconn-reports-34-rise-in-q3-profit-beats-forecasts/ar-AA2hgMDg) [7], while Taiwan's broader index gained 49 percent [7]. The builders who turn Nvidia's silicon into working racks are the ones closing the gap between AI capability and what people actually use, and this quarter the operating line started to show it. Watch whether the margin holds as racks become the whole company, and whether cash comes back before the order book turns. ## Takeaway AI server gear is now more than half of Foxconn's revenue, and the quarter's operating profit grew faster than sales, so the assembler is keeping some of the AI buildout rather than only passing Nvidia volume through. The cash statement is the catch: NT$287 billion of free cash went out in nine months. ## Sources 1.
