FOR IMMEDIATE RELEASE

SONIC AUTOMOTIVE, INC. – HURRICANE AND EARNINGS UPDATE

CHARLOTTE, NC (October 11, 2017) – Sonic Automotive, Inc. (NYSE: SAH) provided an update today on the impact of Hurricanes Harvey and Irma on its operations.

Sonic has nineteen franchise stores and five collision repair centers in the greater Houston market. Hurricane Harvey affected operations at all of Sonic’s Houston market locations during the third quarter. Approximately 20% of Sonic’s consolidated revenues for the first six months of fiscal 2017 were attributable to the Houston market locations. Hurricane Irma affected Sonic’s operations in Florida, Alabama and Georgia in varying degrees. Twenty-four stores in these regions were impacted by Irma, with 11 Florida locations being impacted the most. As of and since September 15, 2017, all of the locations affected by Hurricanes Harvey and Irma were operating, with some locations’ operations being limited due to damaged facilities.

The effect of these events has had a negative impact on third quarter fiscal 2017 results. As of today, Sonic now expects to report GAAP earnings per share from continuing operations for the third quarter of fiscal 2017 ranging between $0.44 and $0.46 and adjusted earnings per share from continuing operations for the third quarter of fiscal 2017 ranging between $0.39 and $0.41. Sonic estimates the negative impact experienced in the third quarter of fiscal 2017 to be offset by a lift of increased automotive retail sales and service activity in the fourth quarter. Accordingly, Sonic expects fiscal 2017 GAAP earnings per share from continuing operations to be between $1.55 and $1.65 and expects fiscal 2017 adjusted earnings per share from continuing operations to be between $1.85 and $1.95. See the attached table for the reconciliation of these adjusted amounts to their corresponding GAAP amounts.
