Interview: John Batten, CEO, Twin Disc

How have major events such as the U.S./China trade war, oil price fall and COVID-19 impacted Twin Disc’s commercial marine business to date, and what adjustments have you made in response?These are the three things that I’ve been highlighting in employee communications and with investors over the last few months. For us, COVID was just the third punch after the other two. China is typically our second largest market after the U.S., and we lost lots of orders to our competitors as the trade war started to affect us. It’s rebounding a little, but it definitely impacted our sales into China.
