Shares of Vista Outdoor Inc. /zigman2/quotes/205852373/composite VSTO +0.97% plunged 11% toward a record low in premarket trading Thursday, after the outdoor sport and ammunition company reported a wider-than-expected loss, sales that fell more than analysts projected and provided a downbeat full-year outlook, citing continued and "unprecedented" challenges in its markets. The net loss for the quarter to June 30 narrowed to $16.6 million, or 29 cents a share, from $52.3 million, or 91 cents a share, in the same period a year ago. Excluding non-recurring items, the adjusted per share loss was 8 cents, wider than the FactSet loss consensus of 3 cents a share. Sales fell 13% to $459.8 million, below the FactSet consensus of $471.4 million. The company cut its fiscal 2020 sales guidance range to $1.79 billion to $1.89 billion from $1.94 billion to $2.03 billion, and said it expects adjusted EPS of 10 cents to 25 cents, which surrounds the FactSet consensus of 22 cents. "We are mitigating unprecedented challenges while making continued progress to a more growth-centric Vista Outdoor," said Chief Executive Chris Metz.
