In the first seven months of 2026, Hon Hai's share of Taiwan-listed EMS revenue fell from 48.0% to 44.8%, while Quanta and Wistron posted cumulative growth of 92.7% and 88.2% — server assemblers are collectively eating into the leader's slice.

01

Hon Hai is still number one — so why is its share shrinking?

Hon Hai's cumulative revenue reached NT$5.59 trillion (~US$175.4 bn) over seven months, far ahead of any peer. July alone grew 54.2% year-on-year.
Yet 37.9% cumulative growth ranks only seventh among 20 sample companies. This means → Hon Hai is growing, just slower than the pack.
The other 19 firms posted 56.9% combined cumulative growth, lifting the subsector total to 47.8%. In plain terms = the industry pie is expanding fast, but Hon Hai is capturing a smaller share of each new slice.
02

Who is taking Hon Hai's share?

Quanta leads with 92.7% cumulative growth; July revenue hit NT$366.27 bn (~US$11.5 bn), more than doubling year-on-year (+131.3%).
Wistron follows at 88.2% cumulative growth, with July revenue of NT$308.22 bn (~US$9.7 bn). Both are now in the trillion-NT$ class.
Quanta, Wistron, and Wiwynn together lifted their combined share from 32.2% to 39.6%. This reflects a near-complete capture of the subsector's incremental revenue — mirroring Hon Hai's 3.2-percentage-point decline almost exactly.
03

How concentrated is this subsector?

The top 10 firms account for 99.5% of monthly revenue. The other 10 share less than 1%. In plain terms = this is effectively a top-tier-only industry.
What makes it unusual: 7 of the 10 largest firms also rank in the top 10 for cumulative growth. This means → in EMS, the big are not just big — they are getting bigger faster.
By comparison, only 4 of 10 overlap in IC design and 3 of 10 in semiconductor equipment. Scale and growth track together far more tightly in EMS.
04

Which small players stand out?

ASRock Rack surged 286.2% year-on-year in July, with revenue of NT$5.14 bn (~US$161 mn) and a 101.7% month-on-month jump.
AMAX grew 197.4% to NT$1.44 bn (~US$45.2 mn) and stated explicitly that its positioning in the AI infrastructure market is gradually taking effect — the most direct AI reference in any subsector monthly filing.
This reflects spillover from AI server demand reaching smaller suppliers, though their absolute scale remains tiny.
05

What does the month-on-month data signal?

8 of 20 firms posted lower July revenue than June, including Quanta (-4.9%), Wistron (-4.2%), Inventec (-11.8%), and Compal (-15.5%).
In plain terms = the annual trend is sharply upward, but the monthly rhythm is uneven — even the fastest growers can dip in any single month.
Pegatron is the only large supplier with negative cumulative growth (-2.0%), and its July revenue also fell 5.8% month-on-month. Three declining firms submitted no explanation.
06

Will Hon Hai's share keep falling?

The core variable is singular: whether Hon Hai's server business can grow fast enough to match Quanta and Wistron's expansion pace.
The gap is wide — Hon Hai at 37.9% cumulative vs. Quanta's 92.7% and Wistron's 88.2%. This means → unless the gap narrows, share erosion is arithmetic certainty.
But Hon Hai's absolute scale remains the industry's largest; 44.8% still dwarfs the second-place player. This reflects a shift from "one dominant leader" to "one leader, several strong challengers" — not a threat to the top position itself.
