PART I – FINANCIAL INFORMATION

Item 1.  Financial Statements

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and with the rules and regulations of the Securities and Exchange Commission ("SEC").  Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements of Sonic Corp. (the “Company”).  In the opinion of management, these financial statements reflect all adjustments of a normal recurring nature, including recurring accruals, necessary for the fair presentation of the Company’s financial position, results of operations and cash flows for the interim periods presented in conformity with GAAP.  In certain situations, recurring accruals, including franchise royalties, are based on more limited information at interim reporting dates than at the Company’s fiscal year end due to the abbreviated reporting period.  Actual results may differ from these estimates.  These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended August 31, 2016,2017, included in the Company’s Annual Report on Form 10-K.  Interim results are not necessarily indicative of the results that may be expected for a full year or any other interim period. The second fiscal quarter is typically the most volatile for the company due to seasonality and weather.

The accompanying financial statements include the accounts of the Company, its wholly owned subsidiaries and a number of Company Drive-Ins in which a subsidiary has a controlling ownership interest.  All intercompany accounts and transactions have been eliminated.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”("ASU") No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled for the transfer of promised goods or services to customers.  The standard also requires additional disclosure regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.  The ASU will replace most of the existing revenue recognition requirements in U.S. GAAP when it becomes effective.  Further, in March 2016, the FASB has issued clarifying guidance with ASU No. 2016-08, “Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” which clarifies the guidance in ASU No. 2014-092016-10, “Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing,” and ASU No. 2016-20, “Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers.” ASU No. 2016-08 provides guidance for evaluating when another party, along with the entity, is involved in providing a good or service to a customer.  In April 2016, the FASB issued ASU No. 2016-10 “Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing,” which clarifies the guidance in ASU No. 2014-09 regarding assessing whether promises to transfer goods or services are distinct, and whether an entity's promise to grant a license provides a customer with a right to use or right to access the entity's intellectual property. In December 2016, the FASB issued ASU No. 2016-20 "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers," which provides corrections or improvements to issues that affect narrow aspects of the guidance issued in ASU No. 2014-09.guidance.

The Company plans to adopt the standardstandards in the first quarter of fiscal year 2019, which aligns with the required adoption date.  The standards are to be applied retrospectively or using a cumulative effect transition method, with early application not permitted.method.  The Company does not believe the new revenue recognition standard will impact the recognition of sales from Company Drive-Ins or the recognition of royalty fees from franchisees.franchisees, nor will it have a material impact to the recognition of gift card breakage. The Company expects the pronouncement will impact the recognition of the initial franchise fee, which is currently recognized upon the opening of a Franchise Drive-In. The impact on these fees hasis not yet been estimated,expected to be material to total revenue, and nothe Company anticipates electing the cumulative effect transition method has been selected.method. The Company is currently evaluatingcontinues to evaluate the effect that this pronouncement will have on the recognition ofprincipal versus agent considerations, other transactions, the financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, “Leases.”  The new standard, which replaces existing lease guidance, requires lessees to recognize on the balance sheet a liability to make lease payments and a corresponding right-of-use asset. The guidance also requires certain qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases. Accounting guidance for lessors is largely unchanged. The standard is effective for fiscal year 2020, with early application permitted. This standard requires adoption based upon a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with optional practical expedients. Based on a preliminary assessment, the Company expects that most of

its operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in a significant increase in the assets and liabilities on the consolidated balance sheet. The Company is continuing its assessment, which may identify additional impacts this standard will have on its consolidated financial statements and related disclosures.

In March 2016, the FASB issued ASU No. 2016-04, “Liabilities – Extinguishment of Liabilities: Recognition of Breakage for Certain Prepaid Stored-Value Products,” which is intended to eliminate current and future diversity in practice related to derecognition of prepaid stored-value product liability in a way that aligns with the new revenue recognition guidance.  The update is effective for fiscal year 2019; however, early adoption is permitted.  The adoption of the update is not expected to have a material impact on the Company’s financial statements.

The Company has reviewed all other recently issued accounting pronouncements and concluded they are not applicable or not expected to be significant to our operations.

The following table sets forth the computation of basic and diluted earnings per share:

In August 2015, the Company’s Board of Directors extended the Company’s share repurchase program, authorizing the Company to purchase up to $145.0 million of its outstanding shares of common stock through August 31, 2016.  The Board of Directors further extended the share repurchase program effective May 2016, authorizing the purchase of up to an additional $155.0 million of our outstanding shares of common stock through August 31, 2017.  During fiscal year 2016, approximately 5.2 million shares were repurchased for a total cost of $148.3 million, resulting in an average price per share of $28.48.

During the first three months of fiscal year 2018, approximately 1.7 million shares were repurchased for a total cost of $40.8 million, resulting in an average price per share of $24.51. The total remaining amount authorized under the share repurchase program as of February 28,November 30, 2017 was $75.4$119.2 million.

Share repurchases may be made from time to time in the open market or otherwise, including through an accelerated share repurchase program, under terms of a Rule 10b5-1 plan, in privately negotiated transactions or in round lot or block transactions.  The share repurchase program may be extended, modified, suspended or discontinued at any time.

Accounts and notes receivable consist of the following:

The Company’s receivables are primarily due from franchisees, all of whom are in the restaurant business.  Substantially all of the notes receivable from franchisees are collateralized by real estate or equipment. The receivables from system funds represent transactions in the normal course of business. Royalties and other trade receivables have decreased primarily as a result of the seasonality of the business.  The decrease in current notes receivable from franchisees is due to short-term financing for refranchised drive-ins and newly constructed drive-ins sold to franchisees that were established in fiscal year 2016 and were repaid in the first quarter of fiscal year 2017. The increase in other current accounts and notes receivable is due to the timing of various receipts and disbursements. The decrease in noncurrent receivables from system funds is due to payment on notes extended in fiscal year 2016 related to the establishment of the Brand Technology Fund.

The Company is involved in various other legal proceedings and has certain unresolved claims pending.  Based on the information currently available, management believes that all such other claims currently pending are either covered by insurance or would not have a material adverse effect on the Company’s business operating results or financial condition.

On December 20, 2013, the Company extended a note purchase agreement to a bank that serves to guarantee the repayment of a franchisee loan, with a term through 2018.  In the event of default by the franchisee, the Company would purchase the franchisee loan from the bank, thereby becoming the note holder and providing an avenue of recourse with the franchisee.  The Company recorded a liability for this guarantee which was based on the Company’s estimate of fair value.  As of February 28,November 30, 2017, the balance of the franchisee’s loan was $5.7$5.5 million.

The Company has obligations under various operating lease agreements with third-party lessors related to the real estate for certain Company Drive-In operations that were sold to franchisees.  Under these agreements, which expire through 2029, the Company remains secondarily liable for the lease payments for which it was responsible as the original lessee.  As of February 28,November 30, 2017, the amount remaining under these guaranteed lease obligations totaled $6.8$14.1 million.  At this time, the Company does not anticipate any material defaults under the foregoing leases; therefore, zero liability has been provided.

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties.  The Company has no financial liabilities that are required to be measured at fair value on a recurring basis.

The Company categorizes its assets and liabilities recorded at fair value based on the following fair value hierarchy established by the FASB:

The Company’s cash equivalents, some of which are included in restricted cash, are carried at cost which approximates fair value and totaled $27.3$70.9 million at February 28,November 30, 2017 and $59.2$73.9 million at August 31, 2016.2017.  This fair value is estimated using Level 1 inputs.

At February 28,November 30, 2017 and August 31, 2016,2017, the fair value of the Company’s Series 2016-1 Senior Secured Fixed Rate Notes, Class A-2 (the “2016 Fixed Rate Notes”) and Series 2013-1 Senior Secured Fixed Rate Notes, Class A-2 (the “2013 Fixed Rate Notes” and, together with the 2016 Fixed Rate Notes, the “Fixed Rate Notes”) approximated the carrying value, including accrued interest, of $578.2 million and $579.6 million, respectively.million.  At February 28,November 30, 2017 the fair value of the Company's Series 2016-1 Senior Secured Variable Funding Notes, Class A-1 (the “2016 Variable Funding Notes” and, together with the Fixed Rate Notes, the “Notes”) approximated the carrying value of $26.1$98.2 million, including accrued interest. At August 31, 20162017 the 2016 Variable Funding Notes had no$60.1 million balance. The fair value of the Notes is estimated using Level 2 inputs from market information available for public debt transactions for companies with ratings that are similar to the Company’s ratings and from information gathered from brokers who trade in the Company’s notes.

During the first quarter of fiscal year 2017, the Company recorded a gain of $3.8 million on the sale of minority investments in franchise operations retained as part of a refranchising transaction that occurred in fiscal year 2009. The gain is reflected in other operating income, net, on the condensed consolidated statement of income.

The following is a summary of the pretax activity recorded as a result of the refranchising initiative ($ in thousands)(in thousands, except number of refranchised Company Drive-Ins):

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

In the Quarterly Report on Form 10-Q, unless the context otherwise requires, the terms “Sonic Corp.,” “the Company,” “we,” “us” and “our” refer to Sonic Corp. and its subsidiaries.

Overview

SystemwideSystem same-store sales decreased 7.4%1.7% during the secondfirst quarter and decreased 4.6% for the first six months of fiscal year 20172018 as compared to an increasea decrease of 6.5% and 5.9%, respectively,2.0% for the same periodsperiod last year. Same-store sales at Company Drive-Ins decreased 8.9%3.2% during the secondfirst quarter and 5.5% for the first six months of fiscal year 20172018 as compared to an increasea decrease of 6.3% and 5.3%, respectively,2.4% for the same periodsperiod last year.  Approximately one percentage point of the decrease in sales for the second quarter and approximately one-half percentage point of the decrease for the first six months of fiscal year 2017 are attributable to one additional day of operations in February 2016 versus February 2017, due to leap year.  The same-store sales decrease reflectsdecreases reflect a decline in traffic, driven by lowersluggish consumer spending in the restaurant industry and aggressive competitive activity, and strong performanceas well as adverse weather in the prior-year periods.quarter. We continue to execute on our long-term strategies, including new technology, people initiatives, product innovation, a greater emphasis on personalized service, targeted value promotions and our fully integrated media strategy.  All of these initiatives drivefuel Sonic’s multi-layered growth strategy, which incorporates same-store sales growth, operating leverage,new drive-in development and deployment of cash, an ascending royalty rate and new drive-in development.cash.  Same-store sales growth is the most important layer and drives operating leverage and increased operating cash flows.

Revenues decreased to $100.2 million for the second quarter and $229.7$105.4 million for the first six monthsquarter of fiscal year 20172018 from $133.2$129.6 million and $279.0 million, respectively, for the same periodsperiod last year, primarily due to a decrease in Company Drive-In sales. The decrease in Company Drive-In sales was a result of refranchising certain Company Drive-Ins during the fourth quarter of fiscal year 2016 and the first half of fiscal year 2017, as part of our initiative to move toward an approximately 95%-franchised system, as well assystem. To a lesser degree the decline in revenues is also attributed to decreased same-store sales. Restaurant margins at Company Drive-Ins were unfavorable by 33010 basis points during the secondfirst quarter of fiscal year 20172018 as compared to the same period last year, reflecting commodity cost inflation and 220 basis points for the first six months of fiscal year 2017, reflecting the de-leveraging impact of same-stores sales decreases, andoffset by the impact of fees paid to the Brand Technology Fund (“BTF”) that was established in the third quarter of fiscal year 2016.refranchising underperforming drive-ins.

SecondFirst quarter results for fiscal year 20172018 reflected net income of $11.0$11.4 million or $0.25$0.29 per diluted share as compared to net income of $10.8$13.1 million or $0.22$0.28 per diluted share for the same periods last year.  Net income and diluted earnings per share for the first six months of fiscal year 2017 were $24.1 million and $0.53, respectively, as compared to net income of $23.3 million or $0.46 per diluted share for the same period last year.  Adjustments to net income are detailed below in Results of Operations.

In June 2016, we announced plans to refranchiseThe Company Drive-Ins as part ofcompleted a refranchising initiative to move toward an approximately 95%-franchised system.in fiscal year 2017. During the first quarter of fiscal year 2017, we completed transactions to refranchise the operations of 56 Company Drive-Ins were refranchised, and the Company retained a non-controlling minority investment in the franchise operations. In the second quarterThe Company recorded a loss of fiscal year 2017, the Company completed additional transactions to refranchise the operations of 54 Company Drive-Ins and retained a non-controlling minority investment in 50 of these refranchised drive-ins.

The following table provides information regarding the number of Company Drive-Ins and Franchise Drive-Ins operating as of the end of the periods indicated as well as the systemwidesystem change in sales and average unit volume.  SystemwideSystem information includes both Company Drive-In and Franchise Drive-In information, which we believe is useful in analyzing the growth of the brand as well as the Company’s revenues since franchisees pay royalties based on a percentage of sales.

Results of Operations

Same-store sales for Company Drive-Ins decreased 8.9% for the second quarter and 5.5%3.2% for the first six monthsquarter of fiscal year 2017,2018, as compared to an increasea decrease of 6.3% and 5.3%2.4% for the same periodsperiod last year, reflecting a decrease in traffic due to lowersluggish consumer spending in the restaurant industry and aggressive competitive activity and strong performance in the prior-year periods.activity.  We continue to focus on our innovative product pipeline, multi-day-part promotions and increased media effectiveness.  Company Drive-In sales decreased $31.0 million during the second quarter and $47.8$24.6 million during the first six monthsquarter of fiscal year 20172018 as compared to the same periodsperiod last year. The decrease in Company Drive-In sales in the secondfirst quarter and first six months of fiscal year 20172018 is primarily due to a decrease in sales from stores soldthe sale of certain Company Drive-Ins to franchisees under the refranchising initiative in fiscal year 2017. Associated sales declines related to those divestitures for the first quarter of $23.8 million and $36.9 million, respectively, and afiscal year 2018 are $23.3 million. The decrease in same-store sales resulted in sales declines for the same period of $6.4 million and $8.6 million, respectively.$2.0 million.

The following table reflects the change in franchise sales, the number of Franchise Drive-Ins, average unit volumes and franchising revenues.  While we do not record Franchise Drive-In sales as revenues, we believe this information is important in understanding our financial performance since these sales are the basis on which we calculate and record franchise royalties.  This information is also indicative of the financial health of our franchisees.

Same-store sales for Franchise Drive-Ins decreased 7.3% for the second quarter and 4.5%1.6% for the first six monthsquarter of fiscal year 20172018 as compared to an increasea decrease of 6.5% and 5.9%, respectively,2.0% for the same periodsperiod last year, reflecting a decrease in traffic due to lowersluggish consumer spending in the restaurant industry and aggressive competitive activity and strong performance in the prior-year periods.activity.  We continue to focus on our innovative product pipeline, multi-day-part promotions and increased media effectiveness. Franchising revenues decreased $1.4increased $0.9 million, or 3.9%, for the second quarter and decreased $1.4 million, or 1.8%2.3%, for the first six monthsquarter of fiscal year 2017,2018, compared to the same periodsperiod last year.  Franchise royalties were negativelypositively impacted by the decrease in same-store sales and were partially offset by an increase in royalties related to franchisee acquisitions of Company Drive-ins and net new unit growth.growth, partially offset by the decrease in same-store sales.

The following analysis of non-GAAP adjustments is intended to supplement the presentation of the Company’s financial results in accordance with GAAP.  We believe the exclusion of these items in evaluating the change in net income and diluted earnings per share for the periods below provides useful information to investors and management regarding the underlying business trends and the performance of our ongoing operations and is helpful for period-to-period and company-to-company comparisons, which management believes will assist investors in analyzing the financial results for the Company and predicting future performance.
