Dow Inc. /zigman2/quotes/203121064/composite DOW -0.93% said it expects the coronavirus to shave about $400 million off first-quarter sales, after business in China saw a 20% to 30% dip in sales. Chief Financial Officer Howard Ungerleider told a JPMorgan industrials conference that the chemicals company expects some additional sales impact but that it's difficult to quantify for now. "However, if I had to size the total impact of COVID on our first quarter based on what I know today, both the impact in China and the knock-on impacts around the world, I would arrange the total impact to the Dow in the first quarter in the $200 million range on EBITDA," the executive told attendees, according to a FactSet transcript. "now, this is clearly a dynamic situation, but I would say the good news is that the cases in China and actually now in South Korea as well have been ramping down, in China for the last couple of weeks in South Korea for approximately a week." China is also returning to more normalized demand levels, he said. Dow shares were down 3.3% premarket.
