On September 17, 2009, Sonic Automotive, Inc. entered into an underwriting agreement with J.P. Morgan Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith, Incorporated (the “Representatives”) for the sale of 9,000,000 shares of Sonic Automotive’s Class A common stock at a public offering price of $10.10 per share. In connection with this offering, Sonic Automotive granted the underwriters a 30-day option to purchase an additional 1,350,000 shares of Class A common stock to cover over allotments. On the same day, Sonic Automotive also entered into an underwriting agreement with the Representatives to sell $150,000,000 aggregate principal amount of convertible senior notes due October 1, 2029. In connection with this offering, Sonic Automotive granted the underwriters a 30-day option to purchase up to an additional $22,500,000 aggregate principal amount of the convertible senior notes to cover over allotments.

On September 18, 2009, the Representatives notified Sonic Automotive that the underwriters were exercising in full their over-allotment option in both the Class A common stock offering and convertible senior notes offering.

Sonic Automotive expects to close these offerings, including with respect to the over-allotments, on September 23, 2009. The total net proceeds from the offerings will be approximately $266.4 million, after deducting underwriters’ discounts and commissions and before offering expenses. Sonic Automotive intends to use these net proceeds to repay all or a portion of the principal amount outstanding on its 6.00% Convertible Senior Secured Notes due 2012 and 4.25% Convertible Senior Subordinated Notes due 2015, including through repurchases of approximately $143 million aggregate principal amount of 4.25% Convertible Senior Subordinated Notes, shortly following the closing of the offerings described above, near par pursuant to separate arrangements entered into from September 17, 2009 through September 23, 2009 between Sonic Automotive and certain holders of the 4.25% Convertible Senior Subordinated Notes following unsolicited offers to sell from those holders.
