Hana Lamphun Q1/21

• LPN recorded sales of +6% YoY

• Recovery in auto parts was strong – we worry chip shortage may impact us in Q2

• Demand for test & measurement was impacted due to material delivery issues

• Wafer scale testing (for cloud) computing increased due to continuing WFH (covid is not over yet!)

• Heart rate monitor sensors saw big increases

• LED lighting for auto remains strong

Over 1m cars impacted by chip shortage YTD

Projections for global auto sales 2019 to 2020 -15% 2020 to 2021 +9%

• Strong growth YoY for auto parts despite issues with semiconductor supplies. Replenishment of depleted stocks in 2020

• Hana’s auto companies are not cancelling any orders and continue to see high demand for auto parts despite IC shortage issues in Q1/21

• A change in JIT strategy may increase the levels of inventory being held.

• Many auto companies have been impacted due to chip shortages which may extend well into the second half of 2021

Hana AYT IC Q1/21

• AYT recorded sales of +15% YoY

• Demand for automotive, industrial, communication, infrastructure and healthcare all saw strong growth - mobile sensors & standard chips driven by 5G was also very strong.

• Adaptors (for fast mobile charging) continued to see strong demand due to major brands not including one with new models.

• Renovation to re-layout existing buildings to create ~25-30% more manufacturing floor is under way and planned to be completed within July.

• New equipment lead-time have increased from ~8 weeks to ~30 weeks, a reflection of the strong demand for IC expansion globally.

• Potential shortages certain suppliers e.g. lead frames raises concern for Q2 – Q3

• Equipment ordering lead time stretches out from ~12 weeks to >36 weeks

Smartphone sales surge 24% YoY driven by Covid affected low sales in Q1/20 & 5G

2021 YoY IC growth revised up again to +13%

Q1/21 Global Semiconductor Sales increase 17.6% YoY & 3.6% QoQ

The Semi bull market is expected to run in 2021 and into at least 1st half 2022

Hana JiaXing Q1/21

• IC sales were strong , YoY growth of 52% but limited by our capacity, mainly for smart phones + other consumer devices

• PCBA sales grew YoY 22% due to last year lock down and consolidation from two our large customers

• RFID cards/readers remained weak due to covid continuity in the West

• Q2 outlooks remains strong especially for IC but long lead times for equipment will mean we cannot benefit until Q3 /4

• Hana China is investing to expand our IC assembly driven by strong domestic demand

• Material shortages may start to have some impact in Q2 as lead times stretch out substantially

Hana Cambodia Q1/21

• KK YoY Q1 sales dropped 16% primarily due to the remote shutdown

• KK has added a few small a/c but hard to win new business due to travel restrictions

• Continuing lock down makes it hard for new customer introduction as customers want to view the plant for any new production start-up.

• We continue to control cost tightly

• Strong cost control has kept losses to a minimum.

15

• HMT recorded sales growth of 27% driven by consumer demand albeit these product have with lower margins.

• Telecom switches demand was very weak due to our main customer getting impacted in the China/US trade tensions. We expect a recovery in the second half as new lines are transferred to us

• Tyre tags also weak as less travel means less tyre usage. A shift to a lower cost version also impacted revenue – we hope volume will pick up in the second half

• HMT’s entry into the “inlay” tag business has got off to a good start with sales already starting in April and over 10m/mo orders onwards and growing. A shortage in IC however will impact our growth rates this year.

Hana Micro Technologies Ohio Q1/21

Q1/21 Global growth start to rebound – despite a mixed vaccine rollout

•China takes off with 18.3% growth

•US grows at 6.3%

•EU struggles to register any growth – some states decline

•Pent up demand will drive consumers

• 3rd waves suppress travel/hospitality

But the Euro Zone disappoints due to slow vaccine rollout

Pent up demand will drive consumer spending in 2021

• Most auto companies announce impact due chip shortages

• Mobiles, gaming, PC, consumer electronics are all starting to feel the impact.

• Companies double orders to ensure supply - exaggerating demand

• Lead times for semiconductor equipment stretches out to over 12 months especially for fab related machinery

• So far Hana have not been materially impacted but this may change in the future as the problem begins to spread to many industries as lead times for materials stretch out and companies over book to build inventory

Q2/21 Outlook Summary

• Continuing strong demand for autos / cloud computing / HRM / 5G / Industrial / Consumer

• Smartphone demand continue driven by 5G, concerns about chip shortages in second half.

• Overall IC demand remains very strong, additional equipment will increase output but long lead time will limit rate of growth

• Third covid wave will drag recovery for travel / hospitality but demand for electronics remains very robust

• US$ starts to weaken as inflations worries subside (for now)

• Material shortages may start to impact us towards the end of Q2 and beyond. Difficult to quantify the magnitude but unlikely Hana can escape

• Initial output of power devices from Korea shipped to interested customers for performance / quality testing – process can take 4-6 months depending on application.
