DESCRIPTION OF BUSINESS</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">El Pollo Loco Holdings, Inc. (“Holdings”) is a Delaware corporation headquartered in Costa Mesa, California. Holdings and its direct and indirect subsidiaries are collectively known as “we,” “us” or the “Company.” The Company’s activities are conducted principally through its indirect wholly-owned subsidiary, El Pollo Loco, Inc. (“EPL”), which develops, franchises, licenses and operates quick-service restaurants under the name El Pollo Loco ®. The restaurants, which are located principally in California but also in Arizona, Nevada, Texas, Utah and Louisiana, specialize in fire-grilling citrus-marinated chicken in a wide variety of contemporary Mexican and LA-inspired entrees, including specialty chicken burritos, chicken quesadillas, chicken tostada salads, chicken tortilla soup, variations on our Pollo Bowl®, Pollo Salads and our Pollo Fit entrees. At December 29, 2021, the Company operated 189 (141 in the greater Los Angeles area) and franchised 291 (135 in the greater Los Angeles area) El Pollo Loco restaurants. In addition, the Company currently licenses one restaurant in the Philippines. The Company’s largest stockholder is Trimaran Pollo Partners, L.L.C. (“LLC”), which is controlled by affiliates of Trimaran Capital, L.L.C. LLC acquired Chicken Acquisition Corp. (“CAC”), a predecessor of Holdings, on November 17, 2005 (the “Acquisition”) and has a 45.8% ownership interest as of December 29, 2021. LLC’s only material asset is its investment in Holdings.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">On April <span style="white-space:pre-wrap;">22, 2014, CAC, the LLC’s wholly owned subsidiary, Chicken Subsidiary Corp (“CSC”) and CSC’s wholly owned subsidiary, the former El Pollo Loco Holdings, Inc. (“Old Holdings”) entered into the following reorganization transactions: (i) Old Holdings merged with and into CSC with CSC continuing as the surviving corporation; (ii) CSC merged with and into CAC with CAC continuing as the surviving corporation and (iii) CAC renamed itself El Pollo Loco Holdings, Inc.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">Holdings has no material assets or operations. Holdings and Holdings’ direct subsidiary, EPL Intermediate, Inc. (“Intermediate”), guarantee EPL’s 2018 Revolver (see Note 6, “Long-Term Debt”) on a full and unconditional basis and Intermediate has no subsidiaries other than EPL. EPL is a separate and distinct legal entity, and has no obligation to make funds available to Intermediate. EPL and Intermediate may pay dividends to Intermediate and to Holdings, respectively.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;">The Company operates in one operating segment. All significant revenues relate to retail sales of food and beverages through either company or franchised restaurants.</p>

Actual results could materially differ from those estimates. The Company’s significant estimates include estimates for impairment of goodwill, intangible assets and property and equipment, insurance reserves, lease accounting matters, stock-based compensation, tax receivable agreement (the “TRA”) liability, contingent liabilities and income tax valuation allowances.</p>

Buildings and facilities leased from others are primarily for restaurants and support facilities. Restaurants are operated under lease arrangements that generally provide for a fixed base rent and, in some instances, contingent rent based on a percentage of gross operating profit or net revenues more than a defined amount. Initial terms of land and restaurant building leases generally have terms of 20 years, exclusive of options to renew. ROU assets and operating and finance lease liabilities are recognized at the lease commencement date, which is the date the Company takes possession of the property. Operating and finance lease liabilities represent the present value of lease payments not yet paid. ROU assets represent the Company’s right to use an underlying asset and are based upon the operating and finance lease liabilities adjusted for prepayments or accrued lease payments, lease incentives, and impairment of ROU assets. To determine the present value of lease payments not yet paid, the Company estimates incremental borrowing rates corresponding to the lease term including reasonably certain renewal periods. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">The Company’s leases generally have escalating rents over the term of the lease, and are recorded on a straight-line basis over the expected lease term. Additionally, tenant incentives used to fund leasehold improvements are recognized when earned and reduce the right-of-use asset related to the lease. These are amortized through the operating lease asset as reductions of expense over the lease term.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">Operating and finance lease liabilities that are based on an index or rate are calculated using the prevailing index or rate at lease commencement. Subsequent escalations in the index or rate and contingent rental payments are recognized as variable lease expenses. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;">Leases of equipment primarily consist of restaurant equipment, computer systems and vehicles. The Company subleases facilities to certain franchisees and other non-related parties which are recorded on a straight-line basis. </p>
