Seoul Semiconductor achieves 1.04 billion US$ record annual revenues for fiscal year 2017

• Reported 2017 revenues of US$ 1.04 billion and an operating profit of
  US$ 92 million, an increase of 16% and 71% year-over-year respectively
  as a result of rising sales across all business divisions
• The increased revenue and profit are attributable to its portfolio of
  differentiated technologies and patents, which are gaining global wide
  recognition from its customers

ANSAN, South Korea–(BUSINESS WIRE)–$KOSDAQ046890 #Acrich–Seoul Semiconductor Co., Ltd. (KOSDAQ 046890), a market leader in LED
(light emitting diode) design and manufacturing, today announced 2017
fiscal year consolidated revenues of US$ 1.04 billion. The 16% rise in
consolidated revenues far exceeds the industry average, which grew 2%
during the same period. The growth of revenue is contributed to
improvements in both general lighting sales and IT product related sales
growing in the mid-teens as well as the automotive lighting business
which grew more than 20%.

The rise in revenue for the general lighting segment was largely due to
an increase in sales of 220V and 370V Acrich MJT products for household
and industrial applications. Other notable revenue increases were
reported for WICOP, an innovative product line of package-less LEDs, as
well as for the Acrich NanoDriver, which incorporates step drive methods
that achieve results greater than those of conventional SMPS technology.
In addition to offering these differentiated technologies, Seoul expects
its SunLike natural spectrum LED technology, which may offer health
benefits for human eyes, to lead the future of LED lighting and become a
large contributor to the future sales and profit for the company.

Researchers who won the Nobel Prize in 2017 were recognized for their
new findings of the impact of light on circadian rhythm in humans. This
has proven to be an important topic in our society and generated great
attention for Dr. Charles Czeisler, the Harvard professor that has
dedicated his research to this particular area. He is now conducting
research study with NASA on how light affects the circadian rhythms of
astronauts.

According to new research, myopia (near-sightedness) increased from 20%
in the 1950s to 80% in 2010 among populations in Asia. Fluorescent
lights and conventional LED light sources emit a strong blue light that
is known to cause eye fatigue, which may later result in retinal damage.
Seoul Semiconductor, together with Toshiba Materials of Japan, has
jointly developed SunLike natural spectrum LED technology, which
provides lighting conditions most similar to actual sun light and can be
seen as a solution that helps to protect human eyes from this potential
damage.

Company outlook

The company provided a revenue guidance of KrW 270 to 290 billion for
the first quarter of 2018. This figure is in range of 5% to 13% on a
year-over-year basis. Although first quarter is normally considered to
be an off-season, the company is showing a positive outlook for growth
from last year for this 2018 fiscal year.

Sangbum Kim, the company’s Chief Financial Officer, has stated that
fiscal year 2017 sales were a result of the company’s relentless efforts
to stay ahead of competition by continuously investing in R&D and
strengthening global sales organizations. In order to further accelerate
revenue growth into the double digit range for 2018, the company plans
to further drive sales of differentiated products such as SunLike while
also shifting more focus to its rapidly growing automotive lighting
business.
