Costa Mesa-based El Pollo Loco Holdings Inc. (Nasdaq: LOCO) shares jumped 23% in midday trading Thursday to a $396 million market cap, a day after the company updated investors on coronavirus-related matters.

The restaurant operator said its same-store sales for the quarter ended March 25 were off 1.5%. Comparable sales were up across restaurants 3.7% in February, prior to stay-at-home orders and the shuttering of non-essential businesses.

The elimination of in-restaurant dining across the industry as a result of COVID-19 isn't hitting El Pollo Loco as hard, with the company saying it historically has had off-premise diners. They account for roughly 78% of sales, about half from drive-thru service.
