Four core markets, with semiconductor & electronics the primary focus

In market terms, Comet remains committed to the four major core markets with strong long-term growth: first and foremost, the semiconductor and electronics sector, which offers great potential for both the plasma control and x-ray businesses. We also remain dedicated to serving the aerospace, automotive and security markets.

The semiconductor and electronics industry is Comet’s key market. Amid the accelerated pace of digitalization, this focus took on even greater significance in 2020. Going forward, we expect to generate up to 70% of our sales from this sector.

In addition, we continue to see attractive long-term potential to use our technology in the aerospace, automotive and security inspection markets. It is true that these “traditional” industries experienced a dramatic decline in sales in 2020 due to the pandemic and structural weakness. However, in the medium and long term, Comet identifies clear opportunities in these markets. Further, these industries are currently undergoing strong adoption of digitalization. They are expected to account for approximately 30% of the Group’s sales in 2025. At the end of the year, an improvement in the auto sector was already noticeable in China, the world’s largest automotive market. Globally, industry experts predict a significant rally in demand for fleet vehicles over the course of 2021 thanks to catch-up effects. As well, given the heightened awareness of climate change, it appears likely that companies and consumers will increasingly switch to electric transport. The situation is quite similar in the aerospace and security inspection sectors. As soon as enough of the population is vaccinated against Covid-19, a gradual recovery in travel and thus in business can be expected.
