Notes to Consolidated Financial Statements

(Unaudited)

Note 1.     Introduction and Basis of Presentation

Denny’s Corporation, or the Company, is one of America’s largest full-service restaurant chains based on number of restaurants. As of September 27, 2023, the Company consisted of 1,644 restaurants, 1,570 of which were franchised/licensed restaurants and 74 of which were company operated.

The Company consists of the Denny’s brand ("Denny's") and the Keke’s Breakfast Café brand (“Keke’s”). Keke’s was acquired on July 20, 2022. As of September 27, 2023, the Denny's brand consisted of 1,588 restaurants, 1,522 of which were franchised/licensed restaurants and 66 of which were company operated. At September 27, 2023, the Keke's brand consisted of 56 restaurants, 48 of which were franchised restaurants and eight of which were company operated.

Our unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim financial information. Therefore, certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of the interim periods presented have been included. Such adjustments are of a normal and recurring nature. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions; however, we believe that our estimates are reasonable.

These interim consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto as of and for the fiscal year ended December 28, 2022 which are contained in our audited Annual Report on Form 10-K for the fiscal year ended December 28, 2022. The results of operations for the interim periods presented are not necessarily indicative of the results for the entire fiscal year ending December 27, 2023. Our significant interim accounting policies include the recognition of advertising and marketing costs, generally in proportion to revenue, and the recognition of income taxes using an estimated annual effective rate.

Note 2.     Summary of Significant Accounting Policies

Newly Adopted Accounting Standards

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” which was later clarified in January 2021 by ASU 2021-01, “Reference Rate Reform (Topic 848): Scope”. Additionally, in December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848”, which allows ASU 2020-04 to be adopted and applied prospectively to contract modifications made on or before December 31, 2024. The guidance provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The Company adopted ASU 2020-04 on March 12, 2020. The adoption of and future elections under this new guidance did not and are not expected to have a material impact on the Company’s consolidated financial position or results of operations. The guidance is effective through December 31, 2024.

Accounting Standards to be Adopted

We reviewed all other newly issued accounting pronouncements and concluded that they are either not applicable to our business or are not expected to have a material effect on our consolidated financial statements as a result of future adoption.

(1)    The fair values of our deferred compensation plan investments are based on the closing market prices of the elected investments and are included in other noncurrent assets in our Consolidated Balance Sheets.

(2)    The fair values of our interest rate swaps are based upon Level 2 inputs, which include valuation models. The key inputs for the valuation models are quoted market prices, interest rates, forward yield curves and credit risk adjustments that are necessary to reflect the probability of default by the counterparty or us. For disclosures about the fair value measurements of our derivative instruments, see Note 7.

(3)    The fair values of our investments are valued using a readily determinable net asset value per share based on the fair value of the underlying securities. There are no significant redemption restrictions associated with these investments.

Fair value measurements as of September 27, 2023:
Assets held and used (1)		$	—	$	1,711
(1)	As of September 27, 2023, impaired assets were written down to their fair value. To determine fair value, we used the income approach, which assumes that the future cash flows reflect current market expectations. These fair value measurements require significant judgment using Level 3 inputs, such as discounted cash flows from operations, which are not observable from the market, directly or indirectly. There is uncertainty in the projected future cash flows used in the Company's impairment analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods.

Assets that are measured at fair value on a non-recurring basis include property, operating right-of-use assets, finance right-of-use assets, goodwill and intangible assets. During the quarter and year-to-date period ended September 27, 2023, we recognized impairment charges of $1.7 million and $1.8 million, respectively, related to certain of these assets. See Note 9.

The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses are deemed to approximate fair value due to the immediate or short-term maturity of these instruments. The fair value of notes receivable approximates the carrying value after consideration of recorded allowances and related risk-based interest rates. The liabilities under our credit facility are carried at historical cost, which approximates fair value. The fair value of our senior secured revolver approximates its carrying value since it is a variable rate facility (Level 2).

Note 7.     Long-Term Debt

The Company and certain of its subsidiaries have a credit facility consisting of a five-year $400 million senior secured revolver (with a $25 million letter of credit sublimit). The maturity date for the credit facility is August 26, 2026. The credit facility includes an accordion feature that would allow us to increase the size of the facility to $450 million. Borrowings bear a tiered interest rate, which is based on the Company's consolidated leverage ratio. On March 31, 2023, the credit facility was amended to change the benchmark interest rate from LIBOR to Adjusted Daily Simple SOFR.

The credit facility is available for working capital, capital expenditures and other general corporate purposes. The credit facility is guaranteed by the Company and its material subsidiaries and is secured by assets of the Company and its subsidiaries, including the stock of its subsidiaries (other than its insurance captive subsidiary). It includes negative covenants that are usual for facilities and transactions of this type. The credit facility also includes certain financial covenants with respect to a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio. We were in compliance with all financial covenants as of September 27, 2023.

As of September 27, 2023, we had outstanding revolver loans of $248.1 million and outstanding letters of credit under the credit facility of $11.5 million. These balances resulted in unused commitments of $140.4 million as of September 27, 2023 under the credit facility.

As of September 27, 2023, borrowings under the credit facility bore interest at a rate of Adjusted Daily Simple SOFR plus 2.25%. Letters of credit under the credit facility bore interest at a rate of 2.38%. The commitment fee, paid on the unused portion of the credit facility, was set to 0.35%.

Prior to considering the impact of our interest rate swaps, described below, the weighted-average interest rate on outstanding revolver loans was 7.66% and 6.37% as of September 27, 2023 and December 28, 2022, respectively. Taking into consideration our interest rate swaps that are designated as cash flow hedges, the weighted-average interest rate of outstanding revolver loans was 5.28% and 5.31% as of September 27, 2023 and December 28, 2022, respectively.

Interest Rate Hedges

We have receive-variable, pay-fixed interest rate swaps to hedge the forecasted cash flows of our floating rate debt. A summary of our interest rate swaps as of September 27, 2023 is as follows:

Trade Date	Effective Date	Maturity Date	Notional Amount			Fair Value		Fixed Rate
			(In thousands)
Swaps designated as cash flow hedges
March 20, 2015	March 29, 2018	March 31, 2025	$	120,000		$	4,937	2.34	%
October 1, 2015	March 29, 2018	March 31, 2026	$	50,000		$	2,851	2.37	%
February 15, 2018	March 31, 2020	December 31, 2033	$	31,000	(1)	$	19,536	3.09	%
Total			$	201,000		$	27,324

(1)     The notional amounts of the swaps entered into on February 15, 2018 increase periodically until they reach the maximum notional amount of $335 million on August 31, 2033.

On March 31, 2023, the Company entered into amendments of its credit facility and interest rate swaps. The amendments transition our credit facility and interest rate swap benchmark interest rates from LIBOR to Adjusted Daily Simple SOFR, as such the fixed rates in the table above have been adjusted to the appropriate fixed rates. The conversion to Adjusted Daily Simple SOFR did not have a material impact on the Company's consolidated financial position or results of operations.

Termination and Designation of Certain Interest Rate Swaps

During the quarter ended March 29, 2023, we terminated a portion of our hedging relationship entered into in 2018 (“2018 Swaps”), reducing the previous maximum notional amount of $425 million on August 31, 2033 to $335 million. As a result, we expect our total swaps to approximate 80% of our outstanding debt prospectively. We received $1.5 million of cash as a result of the termination which is recorded as a component of operating activities in our Consolidated Statement of Cash Flows for the year-to-date period ended September 27, 2023.

In addition, during the quarter ended March 29, 2023, we designated the remaining 2018 Swaps as cash flow hedges of our exposure to variability in future cash flows attributable to variable rate interest payments due on forecasted notional amounts.

Changes in Fair Value of Interest Rate Swaps

To the extent the swaps are highly effective in offsetting the variability of the hedged cash flows, changes in the fair value of the swaps are not included in the Consolidated Statements of Operations but are reported as a component of other comprehensive income (loss). Our interest rate swaps are designated as cash flow hedges with unrealized gains and losses recorded as a component of accumulated other comprehensive loss, net.

As of September 27, 2023, the fair value of the swaps designated as cash flow hedges was an asset of $27.3 million, recorded as a component of other noncurrent assets. The designated swaps have an offsetting amount (before taxes) recorded as a component of accumulated other comprehensive loss, net in our Consolidated Balance Sheets. See Note 13 for amounts recorded in accumulated other comprehensive loss related to interest rate swaps. We expect to reclassify $5.9 million from accumulated other comprehensive loss, net as a reduction to interest expense, net in our Consolidated Statements of Operations related to swaps designated as cash flow hedges during the next 12 months.

For the periods prior to their designation as cash flow hedges, changes in the fair value of the 2018 Swaps were recorded as a component of other nonoperating expense (income), net in our Consolidated Statements of Operations. For the year-to-date period ended September 27, 2023, we recorded expense of $10.6 million, and for the quarter and year-to-date period ended September 28, 2022, we recorded income of $10.8 million and $52.7 million, respectively, as a component of other nonoperating expense (income), net related to the 2018 Swaps resulting from changes in fair value.

Amortization of Certain Amounts Included in Accumulated Other Comprehensive Loss, Net

At September 27, 2023, we had a total of $64.3 million (before taxes) included in accumulated other comprehensive loss, net related to i) the discontinuance of hedge accounting treatment related to certain cash flow hedges in prior years and ii) the fair value of certain swaps at the date of designation as cash flow hedges that are being amortized into our Consolidated Statements of Operations as a component of interest expense, net over the remaining term of the related swap.

13

For the quarter and year-to-date period ended September 27, 2023, we recorded unrealized losses of $0.1 million and $0.2 million, respectively, to interest expense, net. For the quarter and year-to-date period ended September 28, 2022, we recorded unrealized losses of less than $0.1 million to interest expense, net. We expect to amortize $0.6 million from accumulated other comprehensive loss, net to interest expense, net in our Consolidated Statements of Operations related to dedesignated interest rate swaps during the next 12 months.

The Company purchases equipment related to various programs for franchise restaurants, including kitchen and point-of-sale system equipment. We bill our franchisees and recognize revenue when the related equipment is installed, less amounts contributed from the Company, which have been deferred as contract assets in the table above. We recognized $1.7 million and $4.6 million of revenue, recorded as a component of initial and other fees, related to the sale of equipment to franchisees during the quarter and year-to-date period ended September 27, 2023, respectively. We recognized $5.8 million and $13.8 million of revenue, recorded as a component of initial and other fees, related to the sale of equipment to franchisees during the quarter and year-to-date period ended September 28, 2022, respectively.

Deferred gift card liabilities consist of the unredeemed portion of gift cards sold in company restaurants and at third party locations. The balance of deferred gift card liabilities represents our remaining performance obligations to our customers. The balance of deferred gift card liabilities as of September 27, 2023 and December 28, 2022 was $5.7 million and $7.7 million, respectively. During the year-to-date period ended September 27, 2023, we recognized revenue of $0.4 million from gift card redemptions at company restaurants.

Employee Share Awards

During the year-to-date period ended September 27, 2023, we granted certain employees 0.3 million performance share units ("PSUs") with a weighted average grant date fair value of $18.39 per share that vest based on the total shareholder return (“TSR”) of our common stock compared to the TSRs of a group of peer companies and 0.3 million PSUs with a weighted average grant date fair value of $11.90 per share that vest based on our Adjusted EPS growth rate versus plan, as defined under the terms of the award. As the TSR based PSUs contain a market condition, a Monte Carlo valuation was used to determine the grant date fair value. The performance period for these PSUs is the three-year fiscal period beginning December 29, 2022 and ending December 31, 2025. The PSUs will vest and be earned at the end of the performance period at which point the relative TSR and Adjusted EPS growth rate achievement percentages will be applied to the vested units (from 0% to 200% of the target award). We recognize compensation cost associated with 0.5 million of these PSU awards over the entire performance period on a straight-line basis, with compensation cost for the remaining 0.1 million PSU awards recognized on a graded-vesting basis due to the accelerated vesting terms for certain retirement eligible individuals.

During the year-to-date period ended September 27, 2023, we also granted certain employees 0.7 million restricted stock units ("RSUs") with a weighted average grant date fair value of $11.83 per share. These RSUs generally vest evenly over the three-year fiscal period beginning December 29, 2022 and ending December 31, 2025. We recognize compensation cost associated with these RSU awards on a straight-line basis over the entire performance period of the award.

During the year-to-date period ended September 27, 2023, we issued 0.5 million shares of common stock related to vested PSUs and RSUs. In addition, 0.3 million shares of common stock were withheld in lieu of taxes related to vested PSUs and RSUs.

As of September 27, 2023, we had $16.3 million of unrecognized compensation cost related to unvested PSU awards and RSU awards outstanding, which have a weighted average remaining contractual term of 1.9 years.

16

Restricted Stock Units for Board Members

During the year-to-date period ended September 27, 2023, we granted less than 0.1 million RSUs (which are equity classified) with a grant date fair value of $10.71 per unit to non-employee members of our Board of Directors. The RSUs vest after a one year service period. A director may elect to convert these awards into shares of common stock either on a specific date in the future (while still serving as a member of our Board of Directors), upon termination as a member of our Board of Directors, or in three equal annual installments commencing after termination of service as a member of our Board of Directors.

During the year-to-date period ended September 27, 2023, 0.2 million RSUs were converted into shares of common stock.

As of September 27, 2023, we had $0.5 million of unrecognized compensation cost related to unvested RSU awards outstanding, which have a weighted average remaining contractual term of 0.6 years.

Note 11.     Income Taxes

The effective income tax rate was 17.6% for the quarter and 23.7% for the year-to-date period ended September 27, 2023, compared to 24.3% and 25.7% for the prior year periods, respectively. The effective income tax rate for the quarter and year-to-date period ended September 27, 2023 included discrete items relating to share-based compensation of (2.5)% and 0.4%, respectively.

Note 13.     Shareholders' Deficit

Share Repurchases

Our credit facility permits the repurchase of the Company's stock and the payment of cash dividends subject to certain limitations. Our Board of Directors approves share repurchases of our common stock. Under these authorizations, we may, from time to time, purchase shares in the open market (including pre-arranged stock trading plans in accordance with the guidelines specified in Rule 10b5-1 under the Securities Exchange Act of 1934, as amended) or in privately negotiated transactions, subject to market and business conditions. Currently, we are operating under a $250 million share repurchase authorization approved by the Board of Directors in December 2019.

17

During the year-to-date period ended September 27, 2023, we repurchased a total of 3.4 million shares of our common stock for $35.9 million, including excise taxes. This brings the total amount repurchased under the current authorization to $133.4 million, leaving $116.6 million that can be used to repurchase our common stock under this authorization as of September 27, 2023. Repurchased shares are included as treasury stock in our Consolidated Balance Sheets and our Consolidated Statements of Shareholders' Deficit.

As of September 27, 2023, 11.7 million shares were held in treasury stock.

Note 16. Segment Information

We manage our business by brand and as a result have identified two operating segments, Denny’s and Keke’s. In addition, we have identified Denny’s as a reportable segment. The Denny’s reportable segment includes the results of all company and franchised and licensed Denny’s restaurants. Our Keke’s operating segment, which includes the results of all company and franchised Keke's restaurants, is included in Other.

The primary sources of revenues for all operating segments are the sale of food and beverages at our company restaurants and the collection of royalties, advertising revenue, initial and other fees, including occupancy revenue, from restaurants operated by our franchisees. We do not rely on any major customer as a source of sales and the customers and assets of all operating segments are located predominantly in the United States. There are no material transactions between segments.

Management’s measure of segment income is restaurant-level operating margin. The Company defines restaurant-level operating margin as operating income excluding the following three items: general and administrative expenses, depreciation and amortization, and operating (gains), losses and other charges, net. The Company excludes general and administrative expenses, which include primarily non restaurant-level costs associated with support of company and franchised restaurants and other activities at their corporate office. The Company excludes depreciation and amortization expense, substantially all of which is related to company restaurant-level assets, because such expenses represent historical sunk costs which do not reflect current cash outlays for the restaurants. The Company excludes operating (gains), losses and other charges, net, to provide a clearer perspective of its ongoing operating performance. Restaurant-level operating margin is used by our chief operating decision maker (“CODM”) to evaluate restaurant-level operating efficiency and performance.

The following tables present revenues by segment and a reconciliation of restaurant-level operating margin to net income:

The Company urges caution in considering its current trends and any outlook on its operations and financial results disclosed in this report. In addition, certain matters discussed in this report may constitute forward-looking statements. These forward-looking statements, which reflect management's best judgment based on factors currently known, are intended to speak only as of the date such statements are made and involve risks, uncertainties, and other factors that may cause the actual performance of Denny’s Corporation, its subsidiaries, and underlying restaurants to be materially different from the performance indicated or implied by such statements.

Except as may be required by law, the Company expressly disclaims any obligation to update these forward-looking statements to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated events. Factors that could cause actual performance to differ materially from the performance indicated by these forward-looking statements include, among others: economic, public health and political conditions that impact consumer confidence and spending; commodity and labor inflation; the ability to effectively staff restaurants and support personnel; our ability to maintain adequate levels of liquidity for our cash needs, including debt obligations, payment of dividends, planned share repurchases and capital expenditures as well as the ability of our customers, suppliers, franchisees and lenders to access sources of liquidity to provide for their own cash needs; competitive pressures from within the restaurant industry; our ability to integrate and derive the expected benefits from our acquisition of Keke's; the level of success of our operating initiatives and advertising and promotional efforts; adverse publicity; health concerns arising from food-related pandemics, outbreaks of flu viruses, or other diseases; changes in business strategy or development plans; terms and availability of capital; regional weather conditions; overall changes in the general economy (including with regard to energy costs), particularly at the retail level; political environment and geopolitical events (including acts of war and terrorism); and other factors from time to time set forth in the Company’s SEC reports and other filings, including but not limited to the discussion in Management’s Discussion and Analysis and the risks identified in Item 1A. Risk Factors contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 28, 2022 and in the Company's subsequent quarterly reports on Form 10-Q.

Overview

We manage our business by brand and as a result have identified two operating segments, Denny’s and Keke’s. As of September 27, 2023, the Denny's brand consisted of 1,588 restaurants, 1,522 of which were franchised/licensed restaurants and 66 of which were company operated. At September 27, 2023, the Keke's brand consisted of 56 restaurants, 48 of which were franchised restaurants and eight of which were company operated.

In addition, we have identified Denny’s as a reportable segment. The Denny’s reportable segment includes the results of all company and franchised and licensed Denny’s restaurants. We completed the acquisition of Keke's on July 20, 2022. Total revenues at Keke’s for the quarter and three quarters ended September 27, 2023 represented less than 5% of total consolidated revenues, therefore, the Keke’s operating segment is included in Other for segment reporting purposes.

Information discussed in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations relates to the Denny’s brand unless otherwise noted.

Company Restaurant Operations

Company restaurant sales increased $0.9 million, or 1.8%, for the quarter ended September 27, 2023 and $16.1 million, or 11.1%, year-to-date compared to the prior year periods. Company sales from Keke's increased $0.8 million and $8.1 million during the quarter and year-to-date period ended September 27, 2023, respectively, as a result of its acquisition on July 20, 2022. The increases in Denny's sales were primarily driven by increases in guest check average resulting from price increases to partially offset inflationary costs and one additional equivalent unit during the quarter and year-to-date period ended September 27, 2023. Denny's same-store sales decreased 1.4% for the current quarter and increased 4.1% year-to-date as compared to the prior year periods.

Total costs of company restaurant sales as a percentage of company restaurant sales were 86.3% for the quarter ended September 27, 2023 and 86.0% year-to-date compared to 92.8% and 90.7% for the prior year periods, respectively.

Product costs as a percentage of company restaurant sales were 25.6% for the quarter ended September 27, 2023 and 25.9% year-to-date compared to 27.7% and 26.7% for the prior year periods, respectively, primarily due to increased pricing for both the quarter and year-to-date period, partially offset by higher commodity costs for the year-to-date period.

Payroll and benefits as a percentage of company restaurant sales were 37.2% for the quarter ended September 27, 2023 and 37.5% year-to-date compared to 38.6% and 38.3%, respectively, in the prior year periods. The current quarter decreased as a percentage of company restaurant sales primarily due to a 0.6 percentage point decrease in incentive compensation. The year-to-date decrease was primarily due to a 0.8 percentage point decrease in payroll costs due to the leveraging effect of higher sales and a 0.4 percentage point decrease in incentive compensation. The decrease was partially offset by a 0.5 percentage point increase in workers' compensation costs primarily resulting from positive claims development in the prior year period.

Occupancy costs as a percentage of company restaurant sales were 7.9% for the quarter ended September 27, 2023 and 7.7% year-to-date compared to 8.2% and 7.8%, respectively, in the prior year periods. The current quarter decrease as a percentage of company restaurant sales was primarily due to a 0.8 percentage point decrease in general liability insurance costs resulting from negative claims development in the prior year period, partially offset by a 0.4 percentage point increase in rents and property taxes. The year-to-date decrease as a percentage of company restaurant sales was primarily due to a 0.5 percentage point decrease in general liability costs primarily resulting from negative claims development in the prior year period, partially offset by a 0.4 percentage point increase in rents and property taxes.

Other operating expenses were lower as a percentage of company restaurant sales as compared to the prior year periods primarily due to unfavorable developments in certain legal claims during the prior year periods.

Franchise Operations

Franchise and license revenue and costs of franchise and license revenue consisted of the following amounts and percentages of franchise and license revenue for the periods indicated:

Franchise and license revenue decreased $4.2 million, or 6.5%, for the quarter ended September 27, 2023 and decreased $3.1 million, or 1.7%, year-to-date compared to the prior year periods. Royalties increased $0.7 million, or 2.5%, and $5.8 million, or 6.9%, for the current quarter and year-to-date period, respectively, compared to the prior year periods. Royalties from Keke's franchise restaurants increased $0.3 million and $2.9 million during the quarter and year-to-date period ended September 27, 2023, respectively, as a result of its acquisition on July 20, 2022. The increase in royalties also includes Denny's domestic franchise same-store sales increases of 2.1% for the current quarter and 4.3% year-to-date as compared to the prior year periods. These increases were partially offset by the impacts of fewer Denny's franchise equivalent units for the current quarter and year-to-date period.

Advertising revenue increased $0.3 million, or 1.8%, for the current quarter and $2.2 million, or 3.8%, year-to-date compared to the prior year periods. The increases in advertising revenue also include the impact from the 2.1% and 4.3% increases in Denny's franchise domestic same-store sales for the current quarter and year-to-date period, respectively, compared to the prior year periods. The increases during the current quarter and year-to-date period were also partially due to $0.2 million and $0.4 million collected from Keke's franchise restaurants, respectively. These increases were partially offset by the impact of fewer Denny's franchise equivalent units for the current quarter and year-to-date period.

Initial and other fees decreased $4.4 million, or 56.3%, for the quarter ended September 27, 2023 and $9.0 million, or 45.1%, year-to-date compared to the prior year periods. The decreases in initial and other fees primarily resulted from a $4.2 million and $9.2 million decrease in revenue from the sale of equipment to franchisees during the current quarter and year-to-date period, respectively, as our kitchen modernization program has been substantially completed. The revenue recorded related to the sale of equipment has an equal and offsetting expense recorded in other direct costs as described below. Occupancy revenue

24

decreased $0.9 million, or 9.5%, for the current quarter and $2.1 million, or 7.2%, year-to-date compared to the prior year periods, primarily due to lease terminations.

Costs of franchise and license revenue decreased $4.8 million, or 13.8%, for the quarter ended September 27, 2023 and $7.9 million, or 7.8%, year-to-date compared to the prior year periods. Advertising costs increased $0.3 million, or 1.8%, for the current quarter and $2.2 million, or 3.8%, year-to-date, which corresponds to the related advertising revenue increase noted above. Occupancy costs decreased $0.5 million, or 8.8%, for the current quarter and $1.5 million, or 8.2%, year-to-date compared to the prior year periods, primarily due to lease terminations, which corresponds to the related occupancy revenue decrease noted above. Other direct franchise costs decreased $4.6 million, or 47.3%, for the current quarter and $8.5 million, or 33.4%, year-to-date compared to the prior year periods. The decreases in other direct franchise costs were primarily due to a decrease of $4.2 million of expense for the current quarter and $9.2 million of expense year-to-date related to the cost of equipment sold to franchisees as mentioned above. Additionally, other direct franchise costs included an increase of $0.4 million and $0.7 million in franchise administrative costs for the current quarter and year-to-date period, respectively. As a result of the changes in franchise and license revenue discussed above, costs of franchise and license revenue decreased to 48.8% and 49.5% of franchise and license revenue for the quarter and year-to-date period ended September 27, 2023, respectively, from 53.0% and 52.8% for the prior year periods, respectively.

Other Operating Costs and Expenses

Other operating costs and expenses such as general and administrative expenses and depreciation and amortization expense relate to both company and franchise operations.

General and administrative expenses consisted of the following:

	Quarter Ended				Three Quarters Ended
	September 27, 2023		September 28, 2022		September 27, 2023		September 28, 2022
	(In thousands)

Corporate administrative expenses increased $0.8 million for the quarter ended September 27, 2023 and $5.6 million for year-to-date period ended September 27, 2023 compared to the prior year periods. The increases were primarily due to compensation increases and administrative costs related to Keke's. Share-based compensation increased $0.9 million for the current quarter primarily due to having three long-term incentive plans vesting compared to two plans in the prior year quarter as a result of the 2020 long-term incentive plan fully vesting in May 2022. Share-based compensation decreased $1.0 million year-to-date primarily due to forfeitures. Changes in deferred compensation valuation adjustments have offsetting gains or losses on the underlying nonqualified deferred plan investments included as a component of other non-operating expense (income), net, for the corresponding periods.

Depreciation and amortization consisted of the following:

	Quarter Ended				Three Quarters Ended
	September 27, 2023		September 28, 2022		September 27, 2023		September 28, 2022

Gains on sales of assets and other, net for the year-to-date period ended September 27, 2023 were primarily related to the sale of three parcels of real estate. Gains on sales of assets and other, net for the quarter and year-to-date period ended September 28, 2022 were primarily related to the sale of two parcels of real estate.

Restructuring charges and exit costs consisted of the following:

	Quarter Ended				Three Quarters Ended
	September 27, 2023		September 28, 2022		September 27, 2023		September 28, 2022
	(In thousands)
Exit costs	$	12	$	38	$	64	$	88
Severance and other restructuring charges	985		434		2,695		1,209
Total restructuring and exit costs	$	997	$	472	$	2,759	$	1,297

Total restructuring and exit costs increased $0.5 million and $1.5 million for the quarter and year-to-date period ended September 27, 2023, respectively. The current quarter and year-to-date increases were primarily due to severance costs related to changes in our leadership team.

We recorded impairment charges of $1.7 million (consisting of property and right-of-use assets) during the quarter ended September 27, 2023, resulting from our assessment of underperforming restaurants and recoverability of right-of-use assets. We recorded impairment charges of $0.7 million and $1.0 million (consisting of property and right-of-use assets) during the quarter and year-to-date period ended September 28, 2022, respectively, resulting from our assessment of underperforming restaurants and recoverability of right-of-use assets.

Operating income was $14.0 million for the current quarter and $45.1 million year-to-date compared to $15.8 million and $43.0 million, respectively, for the prior year periods.

Interest expense, net consisted of the following:

	Quarter Ended				Three Quarters Ended
	September 27, 2023		September 28, 2022		September 27, 2023		September 28, 2022
	(In thousands)

Total interest expense, net	$	4,381	$	3,691	$	13,288	$	9,529

26

Total cash interest expense, net increased by $0.6 million for the current quarter and $3.5 million year-to-date compared to the prior year periods. These increases were primarily due to increased average borrowings and higher average interest rates, partially offset by our effective interest rate swaps.

Other nonoperating expense (income), net was expense of less than $0.1 million for the current quarter and $9.5 million year-to-date, compared to income of $10.5 million and $49.9 million for the prior year periods, respectively. Other nonoperating expense for the current quarter primarily consisted of $0.1 million of losses on deferred compensation plan investments. The year-to-date period primarily consisted of $10.6 million of losses related to valuation adjustments for dedesignated interest rate hedges, partially offset by gains of $1.0 million on deferred compensation plan investments. Prior year other nonoperating income, net for the quarter primarily consisted of $10.8 million of gains related to dedesignated interest rate swap valuation adjustments, partially offset by losses of $0.3 million on deferred compensation plan investments. The prior year-to-date period primarily consisted of $52.7 million of gains on interest rate swap valuation adjustments, partially offset by $2.6 million of losses on deferred compensation plan investments.

During the quarter ended March 29, 2023, we terminated a portion of our hedging relationship entered into in 2018 (“2018 Swaps”), reducing the previous maximum notional amount of $425 million on August 31, 2033 to $335 million. As a result, we expect our total swaps to approximate 80% of our outstanding debt prospectively. In addition, during the quarter ended March 29, 2023, we designated the remaining 2018 Swaps as cash flow hedges of our exposure to variability in future cash flows attributable to variable rate interest payments due on forecasted notional amounts. As a result, subsequent to the designation of the 2018 Swaps, gains and losses related to these cash flow hedges have been and will be recorded as a component of accumulated other comprehensive loss, net.

Provision for income taxes was $1.7 million for the quarter ended September 27, 2023 and $5.3 million year-to-date, compared to $5.5 million and $21.4 million, respectively, for the prior year periods. The effective tax rate was 17.6% for the current quarter and 23.7% year-to-date, compared to 24.3% and 25.7% for the prior year periods. The effective income tax rate for the quarter and year-to-date period ended September 27, 2023 included the impact of discrete items relating to share-based compensation of (2.5)% and 0.4%, respectively.

Net income was $7.9 million for the quarter ended September 27, 2023 and $17.0 million year-to-date compared to $17.1 million and $61.9 million, respectively, for the prior year periods.

Liquidity and Capital Resources

Our primary sources of liquidity and capital resources are cash generated from operations and borrowings under our credit facility (as described below). Principal uses of cash are operating expenses, capital expenditures, the repurchase of shares of our common stock, and in the prior year, the acquisition of Keke's.

The following table presents a summary of our sources and uses of cash and cash equivalents for the periods indicated:

	Three Quarters Ended
	September 27, 2023		September 28, 2022
	(In thousands)
Net cash provided by operating activities	$	50,768	$	24,950
Net cash used in investing activities	(3,024)		(83,974)
Net cash (used in) provided by financing activities	(50,245)		32,746
Decrease in cash and cash equivalents	$	(2,501)	$	(26,278)

Net cash flows provided by operating activities were $50.8 million for the year-to-date period ended September 27, 2023 compared to $25.0 million for the year-to-date period ended September 28, 2022. The increase in net cash flows provided by operating activities was primarily due to the timing of inventory purchases, receivable collections, and accrual payments related to our franchise kitchen equipment project over the past two years. We believe that our estimated cash flows from operations, combined with our capacity for additional borrowings under our credit facility and cash on hand, will enable us to meet our anticipated cash requirements and fund capital expenditures over the next 12 months.

27

Net cash flows used in investing activities were $3.0 million for the year-to-date period ended September 27, 2023. These cash flows included capital expenditures of $5.5 million, investment purchases of $1.3 million, and a real estate acquisition of $1.2 million, partially offset by net proceeds from the sale of three parcels of real estate for $3.1 million and net investment proceeds of $1.9 million. Net cash flows used in investing activities were $84.0 million for the year-to-date period ended September 28, 2022. These cash flows included $81.5 million for the acquisition of Keke's, $0.8 million for the acquisition of one Denny's franchised restaurant and capital expenditures of $10.1 million, partially offset by proceeds from the sale of two parcels of real estate of $4.1 million, real estate deposit refunds of $3.6 million and net investment proceeds of $0.5 million.

Our principal capital requirements have been largely associated with the following:  

	Three Quarters Ended
	September 27, 2023		September 28, 2022
	(In thousands)
Facilities	$	3,199	$	3,618
New construction	730		29
Remodeling	404		3,738
Information technology	732		2,246
Other	434		515
Capital expenditures	$	5,499	$	10,146

Net cash flows used in financing activities were $50.2 million for the year-to-date period ended September 27, 2023, including cash payments for stock repurchases of $35.4 million, payments of tax withholding on share-based compensation of $3.0 million and net long-term debt payments of $14.8 million, partially offset by net bank overdrafts of $2.9 million. Net cash flows provided by financing activities were $32.7 million for the year-to-date period ended September 28, 2022, which included net long-term debt borrowings of $95.0 million primarily for funding the Keke's acquisition, partially offset by cash payments for stock repurchases of $57.5 million and payments of tax withholding on share-based compensation of $4.8 million.

Our working capital deficit was $56.0 million at September 27, 2023 compared to $43.3 million at December 28, 2022, primarily due to a decrease in receivables and inventories related to our franchise equipment projects during the year-to-date period ended September 27, 2023. We are able to operate with a substantial working capital deficit because (1) restaurant operations and most food service operations are conducted primarily on a cash (and cash equivalent) basis with a low level of accounts receivable, (2) rapid turnover allows for a limited investment in inventories, and (3) accounts payable for food, beverages and supplies usually becomes due after the receipt of cash from the related sales.

Credit Facility

The Company and certain of its subsidiaries have a credit facility consisting of a five-year $400 million senior secured revolver (with a $25 million letter of credit sublimit). The credit facility includes an accordion feature that would allow us to increase the size of the facility to $450 million. Borrowings bear a tiered interest rate, which is based on the Company's consolidated leverage ratio. The maturity date for the credit facility is August 26, 2026.

The credit facility is available for working capital, capital expenditures and other general corporate purposes. The credit facility is guaranteed by the Company and its material subsidiaries and is secured by assets of the Company and its subsidiaries, including the stock of its subsidiaries (other than its insurance captive subsidiary). It includes negative covenants that are usual for facilities and transactions of this type. The credit facility also includes certain financial covenants with respect to a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio. We were in compliance with all financial covenants as of September 27, 2023.

As of September 27, 2023, we had outstanding revolver loans of $248.1 million and outstanding letters of credit under the credit facility of $11.5 million. These balances resulted in unused commitments of $140.4 million as of September 27, 2023 under the credit facility.

As of September 27, 2023, borrowings under the credit facility bore interest at a rate of Adjusted Daily Simple SOFR plus 2.25% and the commitment fee, paid on the unused portion of the credit facility, was set to 0.35%.

28

Prior to considering the impact of our interest rate swaps, described below, the weighted-average interest rate on outstanding revolver loans was 7.66% and 6.37% as of September 27, 2023 and December 28, 2022, respectively. Taking into consideration our interest rate swaps that are designated as cash flow hedges, the weighted-average interest rate of outstanding revolver loans was 5.28% and 5.31% as of September 27, 2023 and December 28, 2022, respectively.

Technology Transformation Initiatives

The Company has committed to investing approximately $4 million toward a new cloud-based restaurant technology platform in domestic franchise restaurants, which will lay the foundation for future technology initiatives to further enhance the guest experience. We currently expect the rollout to occur in 2024 and 2025.

Contractual Obligations

Our future contractual obligations relating to long-term debt and related interest obligations as of September 27, 2023 are as follows:

		Payments Due by Period
		Total		Less than 1 Year		1-2 Years		3-4 Years		5 Years and Thereafter
		(In thousands)
	Long-term debt	$	248,100	$	—	$	—	$	248,100	$	—
	Interest obligations (a)	37,457		3,243		25,474		8,740		—
	Total	$	285,557	$	3,243	$	25,474	$	256,840	$	—
(a)	Interest obligations represent payments related to our long-term debt outstanding at September 27, 2023. For long-term debt with variable rates, we have used the rate applicable at September 27, 2023 to project interest over the periods presented in the table above, taking into consideration the impact of the interest rate swaps that are designated as cash flow hedges for the applicable periods.

See Management's Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for the year ended December 28, 2022 for information concerning other future contractual obligations and commitments.

Critical Accounting Policies and Estimates

For information regarding our Critical Accounting Policies and Estimates, see the "Critical Accounting Policies and Estimates" section in Part II, Item 7, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended December 28, 2022.

Implementation of New Accounting Standards

Information regarding the implementation of new accounting standards is incorporated by reference from Note 2 to our unaudited Consolidated Financial Statements set forth in Part I, Item 1 of this report.

Item 3.     Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We have exposure to interest rate risk related to certain instruments entered into for other than trading purposes. Specifically, as of September 27, 2023, borrowings under our credit facility bore interest at variable rates based on Adjusted Daily Simple SOFR plus 2.25% per annum.

29

We have receive-variable, pay-fixed interest rate swaps to hedge the forecasted cash flows of our floating rate debt. A summary of our interest rate swaps as of September 27, 2023 is as follows:

Trade Date	Effective Date	Maturity Date	Notional Amount			Fair Value		Fixed Rate
			(In thousands)
Swaps designated as cash flow hedges
March 20, 2015	March 29, 2018	March 31, 2025	$	120,000		$	4,937	2.34	%
October 1, 2015	March 29, 2018	March 31, 2026	$	50,000		$	2,851	2.37	%
February 15, 2018	March 31, 2020	December 31, 2033	$	31,000	(1)	$	19,536	3.09	%
Total			$	201,000		$	27,324

(1)     The notional amounts of the swaps entered into on February 15, 2018 increase periodically until they reach the maximum notional amount of $335 million on August 31, 2033.

On March 31, 2023, the Company entered into an amendment of its credit facility. The amendment transitions our credit facility benchmark interest rate from LIBOR to Adjusted Daily Simple SOFR, as such the fixed rates in the table above have been adjusted to the appropriate fixed rates. The conversion to Adjusted Daily Simple SOFR did not have a material impact on the Company's consolidated financial position or results of operations.

As of September 27, 2023, our swaps effectively increased our ratio of fixed rate debt from 4% of total debt to 82% of total debt. Based on the levels of borrowings under the credit facility at September 27, 2023, if interest rates changed by 100 basis points, our annual cash flow and income before taxes would change by $0.3 million. This computation is determined by considering the impact of hypothetical interest rates on the credit facility at September 27, 2023, taking into consideration the interest rate swaps that will be in effect during the next 12 months. However, the nature and amount of our borrowings may vary as a result of future business requirements, market conditions and other factors.

Depending on market considerations, fluctuations in the fair values of our interest rate swaps could be significant. With the exception of these changes in the fair value of our interest rate swaps and in the levels of borrowings under our credit facility, there have been no material changes in our quantitative and qualitative market risks since the prior reporting period. For additional information related to our interest rate swaps, including changes in the fair value, refer to Note 6, Note 7 and Note 13 to our unaudited Consolidated Financial Statements in Part I, Item 1 of this report.

Item 4.     Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, our management conducted an evaluation (under the supervision and with the participation of our Chief Executive Officer, Kelli F. Valade, and our Executive Vice President and Chief Financial Officer, Robert P. Verostek) as of the end of the period covered by this Quarterly Report on Form 10-Q, of the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) under the Exchange Act. Based on that evaluation, Ms. Valade and Mr. Verostek each concluded that our disclosure controls and procedures are effective to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms and (ii) is accumulated and communicated to our management, including Ms. Valade and Mr. Verostek, as appropriate to allow timely decisions regarding required disclosure.

On July 20, 2022, we closed on the acquisition of substantially all of the assets of Keke’s. We are in the process of integrating Keke's into our internal control structure and expect that this effort will be completed in fiscal 2023.

Other than as discussed above, there were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during our fiscal quarter ended September 27, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Introduction and Basis of Presentation

Introduction and Basis of Presentation

Denny’s Corporation, or the Company, is one of America’s largest full-service restaurant chains based on number of restaurants. As of September 27, 2023, the Company consisted of 1,644 restaurants, 1,570 of which were franchised/licensed restaurants and 74 of which were company operated.

The Company consists of the Denny’s brand ("Denny's") and the Keke’s Breakfast Café brand (“Keke’s”). Keke’s was acquired on July 20, 2022. As of September 27, 2023, the Denny's brand consisted of 1,588 restaurants, 1,522 of which were franchised/licensed restaurants and 66 of which were company operated. At September 27, 2023, the Keke's brand consisted of 56 restaurants, 48 of which were franchised restaurants and eight of which were company operated.

Our unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission for interim financial information. Therefore, certain information and notes normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of the interim periods presented have been included. Such adjustments are of a normal and recurring nature. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions; however, we believe that our estimates are reasonable.

These interim consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto as of and for the fiscal year ended December 28, 2022 which are contained in our audited Annual Report on Form 10-K for the fiscal year ended December 28, 2022. The results of operations for the interim periods presented are not necessarily indicative of the results for the entire fiscal year ending December 27, 2023. Our significant interim accounting policies include the recognition of advertising and marketing costs, generally in proportion to revenue, and the recognition of income taxes using an estimated annual effective rate.

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Newly Adopted Accounting Standards

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” which was later clarified in January 2021 by ASU 2021-01, “Reference Rate Reform (Topic 848): Scope”. Additionally, in December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848”, which allows ASU 2020-04 to be adopted and applied prospectively to contract modifications made on or before December 31, 2024. The guidance provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The Company adopted ASU 2020-04 on March 12, 2020. The adoption of and future elections under this new guidance did not and are not expected to have a material impact on the Company’s consolidated financial position or results of operations. The guidance is effective through December 31, 2024.

Accounting Standards to be Adopted

We reviewed all other newly issued accounting pronouncements and concluded that they are either not applicable to our business or are not expected to have a material effect on our consolidated financial statements as a result of future adoption.

(1)    The fair values of our deferred compensation plan investments are based on the closing market prices of the elected investments and are included in other noncurrent assets in our Consolidated Balance Sheets.

(2)    The fair values of our interest rate swaps are based upon Level 2 inputs, which include valuation models. The key inputs for the valuation models are quoted market prices, interest rates, forward yield curves and credit risk adjustments that are necessary to reflect the probability of default by the counterparty or us. For disclosures about the fair value measurements of our derivative instruments, see Note 7.

(3)    The fair values of our investments are valued using a readily determinable net asset value per share based on the fair value of the underlying securities. There are no significant redemption restrictions associated with these investments.

Those assets and liabilities measured at fair value on a non-recurring basis are summarized below:

		Significant Unobservable Inputs (Level 3)		Impairment Charges for the Quarter Ended September 27, 2023

Fair value measurements as of September 27, 2023:
Assets held and used (1)		$	—	$	1,711
(1)	As of September 27, 2023, impaired assets were written down to their fair value. To determine fair value, we used the income approach, which assumes that the future cash flows reflect current market expectations. These fair value measurements require significant judgment using Level 3 inputs, such as discounted cash flows from operations, which are not observable from the market, directly or indirectly. There is uncertainty in the projected future cash flows used in the Company's impairment analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods.

Assets that are measured at fair value on a non-recurring basis include property, operating right-of-use assets, finance right-of-use assets, goodwill and intangible assets. During the quarter and year-to-date period ended September 27, 2023, we recognized impairment charges of $1.7 million and $1.8 million, respectively, related to certain of these assets. See Note 9.

The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued expenses are deemed to approximate fair value due to the immediate or short-term maturity of these instruments. The fair value of notes receivable approximates the carrying value after consideration of recorded allowances and related risk-based interest rates. The liabilities under our credit facility are carried at historical cost, which approximates fair value. The fair value of our senior secured revolver approximates its carrying value since it is a variable rate facility (Level 2).

Debt Disclosure [Abstract]

Long-Term Debt

Long-Term Debt

The Company and certain of its subsidiaries have a credit facility consisting of a five-year $400 million senior secured revolver (with a $25 million letter of credit sublimit). The maturity date for the credit facility is August 26, 2026. The credit facility includes an accordion feature that would allow us to increase the size of the facility to $450 million. Borrowings bear a tiered interest rate, which is based on the Company's consolidated leverage ratio. On March 31, 2023, the credit facility was amended to change the benchmark interest rate from LIBOR to Adjusted Daily Simple SOFR.

The credit facility is available for working capital, capital expenditures and other general corporate purposes. The credit facility is guaranteed by the Company and its material subsidiaries and is secured by assets of the Company and its subsidiaries, including the stock of its subsidiaries (other than its insurance captive subsidiary). It includes negative covenants that are usual for facilities and transactions of this type. The credit facility also includes certain financial covenants with respect to a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio. We were in compliance with all financial covenants as of September 27, 2023.

As of September 27, 2023, we had outstanding revolver loans of $248.1 million and outstanding letters of credit under the credit facility of $11.5 million. These balances resulted in unused commitments of $140.4 million as of September 27, 2023 under the credit facility.

As of September 27, 2023, borrowings under the credit facility bore interest at a rate of Adjusted Daily Simple SOFR plus 2.25%. Letters of credit under the credit facility bore interest at a rate of 2.38%. The commitment fee, paid on the unused portion of the credit facility, was set to 0.35%.

Prior to considering the impact of our interest rate swaps, described below, the weighted-average interest rate on outstanding revolver loans was 7.66% and 6.37% as of September 27, 2023 and December 28, 2022, respectively. Taking into consideration our interest rate swaps that are designated as cash flow hedges, the weighted-average interest rate of outstanding revolver loans was 5.28% and 5.31% as of September 27, 2023 and December 28, 2022, respectively.

Interest Rate Hedges

We have receive-variable, pay-fixed interest rate swaps to hedge the forecasted cash flows of our floating rate debt. A summary of our interest rate swaps as of September 27, 2023 is as follows:

Trade Date	Effective Date	Maturity Date	Notional Amount			Fair Value		Fixed Rate
			(In thousands)
Swaps designated as cash flow hedges
March 20, 2015	March 29, 2018	March 31, 2025	$	120,000		$	4,937	2.34	%
October 1, 2015	March 29, 2018	March 31, 2026	$	50,000		$	2,851	2.37	%
February 15, 2018	March 31, 2020	December 31, 2033	$	31,000	(1)	$	19,536	3.09	%
Total			$	201,000		$	27,324

(1)     The notional amounts of the swaps entered into on February 15, 2018 increase periodically until they reach the maximum notional amount of $335 million on August 31, 2033.

On March 31, 2023, the Company entered into amendments of its credit facility and interest rate swaps. The amendments transition our credit facility and interest rate swap benchmark interest rates from LIBOR to Adjusted Daily Simple SOFR, as such the fixed rates in the table above have been adjusted to the appropriate fixed rates. The conversion to Adjusted Daily Simple SOFR did not have a material impact on the Company's consolidated financial position or results of operations.

Termination and Designation of Certain Interest Rate Swaps

During the quarter ended March 29, 2023, we terminated a portion of our hedging relationship entered into in 2018 (“2018 Swaps”), reducing the previous maximum notional amount of $425 million on August 31, 2033 to $335 million. As a result, we expect our total swaps to approximate 80% of our outstanding debt prospectively. We received $1.5 million of cash as a result of the termination which is recorded as a component of operating activities in our Consolidated Statement of Cash Flows for the year-to-date period ended September 27, 2023.

In addition, during the quarter ended March 29, 2023, we designated the remaining 2018 Swaps as cash flow hedges of our exposure to variability in future cash flows attributable to variable rate interest payments due on forecasted notional amounts.

Changes in Fair Value of Interest Rate Swaps

To the extent the swaps are highly effective in offsetting the variability of the hedged cash flows, changes in the fair value of the swaps are not included in the Consolidated Statements of Operations but are reported as a component of other comprehensive income (loss). Our interest rate swaps are designated as cash flow hedges with unrealized gains and losses recorded as a component of accumulated other comprehensive loss, net.

As of September 27, 2023, the fair value of the swaps designated as cash flow hedges was an asset of $27.3 million, recorded as a component of other noncurrent assets. The designated swaps have an offsetting amount (before taxes) recorded as a component of accumulated other comprehensive loss, net in our Consolidated Balance Sheets. See Note 13 for amounts recorded in accumulated other comprehensive loss related to interest rate swaps. We expect to reclassify $5.9 million from accumulated other comprehensive loss, net as a reduction to interest expense, net in our Consolidated Statements of Operations related to swaps designated as cash flow hedges during the next 12 months.

For the periods prior to their designation as cash flow hedges, changes in the fair value of the 2018 Swaps were recorded as a component of other nonoperating expense (income), net in our Consolidated Statements of Operations. For the year-to-date period ended September 27, 2023, we recorded expense of $10.6 million, and for the quarter and year-to-date period ended September 28, 2022, we recorded income of $10.8 million and $52.7 million, respectively, as a component of other nonoperating expense (income), net related to the 2018 Swaps resulting from changes in fair value.

Amortization of Certain Amounts Included in Accumulated Other Comprehensive Loss, Net

At September 27, 2023, we had a total of $64.3 million (before taxes) included in accumulated other comprehensive loss, net related to i) the discontinuance of hedge accounting treatment related to certain cash flow hedges in prior years and ii) the fair value of certain swaps at the date of designation as cash flow hedges that are being amortized into our Consolidated Statements of Operations as a component of interest expense, net over the remaining term of the related swap.

For the quarter and year-to-date period ended September 27, 2023, we recorded unrealized losses of $0.1 million and $0.2 million, respectively, to interest expense, net. For the quarter and year-to-date period ended September 28, 2022, we recorded unrealized losses of less than $0.1 million to interest expense, net. We expect to amortize $0.6 million from accumulated other comprehensive loss, net to interest expense, net in our Consolidated Statements of Operations related to dedesignated interest rate swaps during the next 12 months.

Employee Share Awards

During the year-to-date period ended September 27, 2023, we granted certain employees 0.3 million performance share units ("PSUs") with a weighted average grant date fair value of $18.39 per share that vest based on the total shareholder return (“TSR”) of our common stock compared to the TSRs of a group of peer companies and 0.3 million PSUs with a weighted average grant date fair value of $11.90 per share that vest based on our Adjusted EPS growth rate versus plan, as defined under the terms of the award. As the TSR based PSUs contain a market condition, a Monte Carlo valuation was used to determine the grant date fair value. The performance period for these PSUs is the three-year fiscal period beginning December 29, 2022 and ending December 31, 2025. The PSUs will vest and be earned at the end of the performance period at which point the relative TSR and Adjusted EPS growth rate achievement percentages will be applied to the vested units (from 0% to 200% of the target award). We recognize compensation cost associated with 0.5 million of these PSU awards over the entire performance period on a straight-line basis, with compensation cost for the remaining 0.1 million PSU awards recognized on a graded-vesting basis due to the accelerated vesting terms for certain retirement eligible individuals.

During the year-to-date period ended September 27, 2023, we also granted certain employees 0.7 million restricted stock units ("RSUs") with a weighted average grant date fair value of $11.83 per share. These RSUs generally vest evenly over the three-year fiscal period beginning December 29, 2022 and ending December 31, 2025. We recognize compensation cost associated with these RSU awards on a straight-line basis over the entire performance period of the award.

During the year-to-date period ended September 27, 2023, we issued 0.5 million shares of common stock related to vested PSUs and RSUs. In addition, 0.3 million shares of common stock were withheld in lieu of taxes related to vested PSUs and RSUs.

As of September 27, 2023, we had $16.3 million of unrecognized compensation cost related to unvested PSU awards and RSU awards outstanding, which have a weighted average remaining contractual term of 1.9 years.

Restricted Stock Units for Board Members

During the year-to-date period ended September 27, 2023, we granted less than 0.1 million RSUs (which are equity classified) with a grant date fair value of $10.71 per unit to non-employee members of our Board of Directors. The RSUs vest after a one year service period. A director may elect to convert these awards into shares of common stock either on a specific date in the future (while still serving as a member of our Board of Directors), upon termination as a member of our Board of Directors, or in three equal annual installments commencing after termination of service as a member of our Board of Directors.

During the year-to-date period ended September 27, 2023, 0.2 million RSUs were converted into shares of common stock.

As of September 27, 2023, we had $0.5 million of unrecognized compensation cost related to unvested RSU awards outstanding, which have a weighted average remaining contractual term of 0.6 years.

Share Repurchases

Our credit facility permits the repurchase of the Company's stock and the payment of cash dividends subject to certain limitations. Our Board of Directors approves share repurchases of our common stock. Under these authorizations, we may, from time to time, purchase shares in the open market (including pre-arranged stock trading plans in accordance with the guidelines specified in Rule 10b5-1 under the Securities Exchange Act of 1934, as amended) or in privately negotiated transactions, subject to market and business conditions. Currently, we are operating under a $250 million share repurchase authorization approved by the Board of Directors in December 2019.

During the year-to-date period ended September 27, 2023, we repurchased a total of 3.4 million shares of our common stock for $35.9 million, including excise taxes. This brings the total amount repurchased under the current authorization to $133.4 million, leaving $116.6 million that can be used to repurchase our common stock under this authorization as of September 27, 2023. Repurchased shares are included as treasury stock in our Consolidated Balance Sheets and our Consolidated Statements of Shareholders' Deficit.

As of September 27, 2023, 11.7 million shares were held in treasury stock.

The Denny’s reportable segment includes the results of all company and franchised and licensed Denny’s restaurants. Our Keke’s operating segment, which includes the results of all company and franchised Keke's restaurants, is included in Other.

The primary sources of revenues for all operating segments are the sale of food and beverages at our company restaurants and the collection of royalties, advertising revenue, initial and other fees, including occupancy revenue, from restaurants operated by our franchisees. We do not rely on any major customer as a source of sales and the customers and assets of all operating segments are located predominantly in the United States. There are no material transactions between segments.

Management’s measure of segment income is restaurant-level operating margin. The Company defines restaurant-level operating margin as operating income excluding the following three items: general and administrative expenses, depreciation and amortization, and operating (gains), losses and other charges, net. The Company excludes general and administrative expenses, which include primarily non restaurant-level costs associated with support of company and franchised restaurants and other activities at their corporate office. The Company excludes depreciation and amortization expense, substantially all of which is related to company restaurant-level assets, because such expenses represent historical sunk costs which do not reflect current cash outlays for the restaurants. The Company excludes operating (gains), losses and other charges, net, to provide a clearer perspective of its ongoing operating performance. Restaurant-level operating margin is used by our chief operating decision maker (“CODM”) to evaluate restaurant-level operating efficiency and performance.

The following tables present revenues by segment and a reconciliation of restaurant-level operating margin to net income:

Accounting Policies [Abstract]

Newly Adopted Accounting Standards and Accounting Standards to be Adopted

Newly Adopted Accounting Standards

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” which was later clarified in January 2021 by ASU 2021-01, “Reference Rate Reform (Topic 848): Scope”. Additionally, in December 2022, the FASB issued ASU 2022-06, “Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848”, which allows ASU 2020-04 to be adopted and applied prospectively to contract modifications made on or before December 31, 2024. The guidance provides optional guidance, for a limited time, to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The Company adopted ASU 2020-04 on March 12, 2020. The adoption of and future elections under this new guidance did not and are not expected to have a material impact on the Company’s consolidated financial position or results of operations. The guidance is effective through December 31, 2024.

Accounting Standards to be Adopted

We reviewed all other newly issued accounting pronouncements and concluded that they are either not applicable to our business or are not expected to have a material effect on our consolidated financial statements as a result of future adoption.

Financial assets and liabilities measured at fair value on a recurring basis are summarized below: 

	Total		Quoted Prices in Active Markets for Identical Assets/Liabilities (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
	(In thousands)
Fair value measurements as of September 27, 2023:

Investments (3)	1,746		—		1,746		—
Total	$	32,611	$	10,818	$	21,793	$	—

(1)    The fair values of our deferred compensation plan investments are based on the closing market prices of the elected investments and are included in other noncurrent assets in our Consolidated Balance Sheets.

(2)    The fair values of our interest rate swaps are based upon Level 2 inputs, which include valuation models. The key inputs for the valuation models are quoted market prices, interest rates, forward yield curves and credit risk adjustments that are necessary to reflect the probability of default by the counterparty or us. For disclosures about the fair value measurements of our derivative instruments, see Note 7.

(3)    The fair values of our investments are valued using a readily determinable net asset value per share based on the fair value of the underlying securities. There are no significant redemption restrictions associated with these investments.

Schedule of Financial Assets and Liabilities Measured at Fair Value on a Non - Recurring Basis

Those assets and liabilities measured at fair value on a non-recurring basis are summarized below:

		Significant Unobservable Inputs (Level 3)		Impairment Charges for the Quarter Ended September 27, 2023
		(In thousands)
Fair value measurements as of September 27, 2023:
Assets held and used (1)		$	—	$	1,711
(1)	As of September 27, 2023, impaired assets were written down to their fair value. To determine fair value, we used the income approach, which assumes that the future cash flows reflect current market expectations. These fair value measurements require significant judgment using Level 3 inputs, such as discounted cash flows from operations, which are not observable from the market, directly or indirectly. There is uncertainty in the projected future cash flows used in the Company's impairment analysis, which requires the use of estimates and assumptions. If actual performance does not achieve the projections, or if the assumptions used change in the future, the Company may be required to recognize impairment charges in future periods.
