Del Taco Restaurants, Inc. (Nasdaq: TACO, TACOW) (the “Company,” “we” or “our”) today announced that it has increased from 6,750,000 to 7,750,000 the number of warrants subject to its previously announced offer to exchange (“Offer to Exchange”) 0.2780 shares of the Company’s common stock (“Shares”) for each outstanding Company warrant exercisable for Shares at an exercise price of $11.50 per Share (the “Warrants”) (approximately one Share for every 3.6 Warrants tendered). The Company also announced that the Offer to Exchange has been extended until 11:59 p.m., Eastern time, on August 8, 2016, unless further extended or terminated. The Offer to Exchange was previously scheduled to expire at 11:59 p.m., Eastern time, on August 5, 2016. As of July 22, 2016, 4,500 Warrants have been tendered and not withdrawn. In addition, all of our directors and officers who beneficially own Warrants have agreed to tender not less than 1,500,000 of their Warrants.

Except for the increase in the number of Warrants subject to the Offer to Exchange and the extension of the expiration date, all of the material terms and conditions set forth in the Offer to Exchange, the related letter of transmittal and the other offer materials for the Warrant tender offer remain unchanged. The Company will mail to the Warrant holders a supplement to the Offer to Exchange reflecting the increased size of the Warrant tender offer and the extension of the expiration date.

The Company will exchange all Warrants properly tendered and not properly withdrawn prior to the expiration of the Offer to Exchange, subject to proration, as described in the Offer to Exchange Letter that was filed with the U.S. Securities and Exchange Commission (the “SEC”) and distributed to Warrant holders. Because of the proration provisions described in the Offer to Exchange Letter, the Company may exchange less than all of the Warrants tendered by a Warrant holder if more than an aggregate of 7,750,000 Warrants are properly tendered and not properly withdrawn.

None of the Company, its board of directors, officers or employees, nor the financial advisor, depositary or the information agent makes any recommendations to Warrant holders as to whether to tender or refrain from tendering their Warrants pursuant to the Offer to Exchange Letter. Warrant holders must decide how many Warrants they will tender, if any.

The financial advisor for the Offer to Exchange is Piper Jaffray & Co. The information agent for the Offer to Exchange is Morrow Sodali. The depositary for the Offer to Exchange is Continental Stock Transfer & Trust Company.
