POTBELLY CORPORATION AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Organization and Other Matters

Business

Potbelly Corporation (the “Company” or “Potbelly”), through its wholly owned subsidiaries, operates Potbelly Sandwich Works sandwich shops in 23 states and the District of Columbia. As of September 28, 2014, the Company had 319 company-operated shops. During the 39 weeks ended September 28, 2014, the Company opened 23 new company-operated shops and closed no shops.

The Company also sells and administers franchises of new Potbelly Sandwich Works sandwich shops. The first domestic and international franchise locations administered by the Company opened during February 2011. As of September 28, 2014, 14 franchised shops were in operation domestically and 12 franchised shops were in operation internationally. During the 39 weeks ended September 28, 2014, the Company opened four franchised shops and closed one franchised shop.

Basis of Presentation

The unaudited condensed consolidated financial statements and notes herein should be read in conjunction with the audited consolidated financial statements of Potbelly Corporation and its subsidiaries and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2013. The unaudited condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. In the opinion of management, all adjustments, which are of a normal and recurring nature (except as otherwise noted), that are necessary to present fairly the Company’s financial position as of December 29, 2013 and September 28, 2014, its statement of operations for the 13 and 39 weeks ended September 29, 2013 and September 28, 2014 and its statement of cash flows for the 39 weeks ended September 29, 2013 and September 28, 2014 have been included. The consolidated statements of operations for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year.

The Company does not have any components of other comprehensive income (loss) recorded within its consolidated financial statements, and, therefore, does not separately present a statement of comprehensive income (loss) in its consolidated financial statements.

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of Potbelly Corporation; its wholly owned subsidiary, Potbelly Illinois, Inc. (“PII”); PII’s wholly owned subsidiaries, Potbelly Franchising, LLC, Potbelly Sandwich Works, LLC (“LLC”) and 16 of LLC’s wholly owned subsidiaries and the LLC’s two joint ventures, collectively, the “Company.” All significant intercompany balances and transactions have been eliminated in consolidation. For the Company’s consolidated joint ventures, non-controlling interest represents the non-controlling partners’ share of the assets, liabilities and operations related to their respective joint venture investments. The Company has ownership interests ranging from 65-75% in these consolidated joint ventures.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions, primarily related to long-lived assets, income taxes, stock-based compensation and common stock equity valuations, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Fiscal Year

The Company uses a 52/53-week fiscal year that ends on the last Sunday of the calendar year. Approximately every five or six years a 53rd week is added. Fiscal 2013 and 2014 each consist of 52 weeks. The fiscal quarters ended September 29, 2013 and September 28, 2014 each consisted of 13 weeks.

POTBELLY CORPORATION AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements

(2) Fair Value Measurements

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and all other current liabilities approximate fair values due to the short maturities of these balances.

The Company assesses potential impairments to its long-lived assets, which includes property and equipment, whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. Shop-level assets are grouped at the individual shop-level for the purpose of the impairment assessment. Recoverability of an asset is measured by a comparison of the carrying amount of an asset to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. The fair value of the shop assets was determined using the discounted future cash flow method of anticipated cash flows through the shop’s lease-end date using fair value measurement inputs classified as Level 3. Level 3 inputs are derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. After performing a periodic review of our shops during each quarter of 2014, it was determined that indicators of impairment were present for certain shops as a result of continued underperformance of shop profitability. We performed an impairment analysis related to these shops and recorded impairment charges of $1.3 million and $2.1 million for the 13 and 39 weeks ended September 28, 2014, respectively, related to the excess of the carrying amounts recorded on our balance sheet over the identified shops’ estimated fair values.

In the third fiscal quarter of 2014, the Company established a non-qualified deferred compensation plan, “Potbelly Non-Qualified Deferred Compensation Plan,” which allows highly compensated employees to defer a portion of their base salary and variable compensation each plan year. The Company maintains a rabbi trust to fund obligations under the deferred compensation plan. Amounts in the rabbi trust are invested in mutual funds. The investments in the rabbi trust are designated as trading securities and carried at fair value. Fair market value of investments in the rabbi trust is measured using Level 1 inputs (quoted prices for identical assets in active markets). As of September 28, 2014, the fair value of the investments in the rabbi trust was $16 thousand, which is included in other assets in the condensed consolidated balance sheet. The Company records trading gains and losses in general and administrative expenses in the condensed consolidated statement of operations, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect its exposure to liabilities for payment under the deferred plan. For the three months ended September 28, 2014, the Company recorded an immaterial amount of unrealized losses on investments held in the rabbi trust.

(3) Earnings per share

Basic income (loss) per common share attributable to common stockholders is calculated using the weighted average number of common shares outstanding for the period. For the 13 and 39 weeks ended September 29, 2013, diluted (loss) per common share attributable to common stockholders was computed by dividing the (loss) allocated to common stockholders utilizing the two-class method by the weighted average number of fully diluted common shares outstanding. In periods with net income attributable to common stockholders, the Company’s redeemable convertible preferred stock were all considered participating securities requiring the two-class method to calculate basic and diluted earnings per share. However, in periods of a net (loss) attributable to common stockholders, the redeemable convertible preferred stock were excluded from the computation of basic earnings per share due to the fact that they were not required to fund losses and the redemption amount was not reduced as a result of losses. For the 13 and 39 weeks ended September 29, 2013, the dilutive securities did not include stock options awarded to employees that had a performance condition requiring the completion of an initial public offering of common stock, as that performance condition was not satisfied at the reporting date and the holders of these options had no rights in our undistributed earnings until that time. On October 9, 2013, the Company completed an initial public offering. Effective upon the closing of such offering, all of the shares of preferred stock and non-voting common stock converted into common stock. As a result of the conversion, for subsequent reporting periods, the Company no longer utilized the two-class method in its calculation of diluted income (loss) per common share attributable to common stockholders. For the 13 and 39 weeks ended September 28, 2014, diluted income (loss) per common share attributable to common stockholders was calculated using income available to common shareholders divided by diluted weighted-average shares of common stock outstanding during the period.

(4) Income Taxes

The Company recognized income tax expense of $2.5 million on pre-tax income of $6.1 million, or an effective tax rate of 40.3%, for the 39 weeks ended September 28, 2014, compared to income tax expense of $2.8 million on pre-tax income of $7.8 million or an effective tax rate of 36.0%, for the 39 weeks ended September 29, 2013. The difference between the statutory rate and the effective tax rate is primarily attributable to state income taxes offset by certain federal and state tax credits. The increase in the effective tax rate primarily relates to the expiration of certain federal income tax credits for 2014 that were available in prior years as well as provision to return adjustments.

(5) Capital Stock

On October 9, 2013, the Company completed an initial public offering. Effective upon the closing of such offering, all shares of preferred stock and non-voting common stock converted into common stock. The terms of the non-voting common stock provided that all shares of non-voting common stock would convert into voting common stock on a 1:1 basis immediately prior to the closing of an underwritten IPO or sale of the Company. The redeemable convertible preferred stock included down-round provisions which would adjust the conversion price for any additional stock issued without consideration or for a consideration per share less than the respective conversion price for one or more of the series of preferred stock in effect immediately prior to the issuance of such additional stock. Each share of common stock has the same relative rights and was identical in all respects to each other share of common stock. Each holder of shares of common stock is entitled to one vote for each share held by such holder at all meetings of stockholders.

On August 1, 2014, the Company’s Board of Directors authorized a share repurchase program of up to $35.0 million of the Company’s common stock. Under this program, the Company may, from time to time, purchase shares in the open market (including in 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. During the 13 weeks ended September 28, 2014, the Company repurchased 471,290 shares of its common stock for approximately $5.8 million in open market transactions. As of September 28, 2014, the remaining dollar value of authorization under the share repurchase program was $29.2 million. Repurchased shares are included as treasury stock in the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Redeemable Convertible Preferred Stock and Equity.

(6) Stock-Based Compensation

Throughout the 39 weeks ending September 28, 2014, the Company issued 292,767 stock options under the 2013 Long-Term Incentive Plan to eligible employees and key executives. The fair value of the options was determined using the Black-Scholes option pricing model. The weighted average common stock fair value of options granted during the 39 weeks ended September 28, 2014 was $19.58 per share, as estimated using the following weighted average assumptions: expected life of options – seven years; volatility- 49.36%; risk-free interest rate – 1.28%; and dividend yield – 0.00%. The Company used the simplified method for determining the expected life of the options. Due to the lack of historical data as a newly public company, the Company calculated the specific stock price volatility using a blended volatility rate based on comparable publicly traded companies.

A summary of activity for the 39 weeks ended September 28, 2014 is as follows:


Options	Shares (Thousands)			Weighted Average Exercise Price		Aggregate Intrinsic Value (Thousands)		Weighted Average Remaining Term (Years)
Outstanding—December 29, 2013		5,030		$	9.41	$	78,575		6.31

Granted		293			19.58
Exercised		(339	)		8.81
Canceled		(105	)		11.64
Outstanding—September 28, 2014		4,879			10.01	$	12,136		5.81

Exercisable—September 28, 2014		3,680			8.99	$	11,910		5.94

During the 39 weeks ended September 28, 2014, the Company issued 28,240 shares of unrestricted common stock to certain non-employee members of its Board of Directors. The unrestricted stock had a weighted average grant-date share price of $15.29 upon issuance. The Company recorded $0.4 million in stock-based compensation expense, with a corresponding increase to additional paid-in capital, related to the issuance of common stock.

In accordance with ASC Topic 718, Compensation—Stock Compensation, stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite employee service period, which is generally the vesting period of the grant, with a corresponding increase to additional paid-in-capital. For the 13 and 39 weeks ended September 28, 2014, the Company recognized stock-based compensation expense of $0.6 million and $2.0 million, respectively, which includes $32 thousand and $0.4 million related to the unrestricted common stock granted during 2014, respectively. For the 13 and 39 weeks ended September 29, 2013, the Company recognized stock-based compensation expense of $1.2 million and $2.4 million, respectively. As of September 28, 2014, the unrecognized stock-based compensation expense was $6.0 million, which will be recognized through fiscal year 2018. The Company records stock-based compensation expense within general and administrative expenses in the consolidated statements of operations.

Revenues

Total revenues increased by $6.7 million, or 8.5%, to $84.7 million during the 13 weeks ended September 28, 2014, from $78.0 million during the 13 weeks ended September 29, 2013. The increase in revenues primarily consisted of an increase of $6.2 million in sales from shops not yet in our company-operated comparable store sales base, a $0.1 million increase in franchise revenues and a $0.4 million, or 0.5%, increase in company-operated comparable store sales. The increase in company-operated comparable store sales resulted from an increase in average check from certain menu price increases and menu mix, partially offset by a reduction in traffic.

Cost of Goods Sold

Cost of goods sold increased by $1.0 million, or 4.5%, to $24.0 million during the 13 weeks ended September 28, 2014, compared to $23.0 million during the 13 weeks ended September 29, 2013, primarily due to the increase in revenues. As a percentage of revenues, cost of goods sold decreased to 28.4% during the 13 weeks ended September 28, 2014, from 29.5% during the 13 weeks ended September 29, 2013, primarily driven by certain menu price increases as well as volume-based rebates from certain vendors.

Labor and Related Expenses

Labor and related expenses increased by $2.5 million, or 12.0%, to $23.8 million during the 13 weeks ended September 28, 2014, from $21.2 million during the 13 weeks ended September 29, 2013, primarily due to new shop openings. As a percentage of revenues, labor and related expenses increased to 28.1% during the 13 weeks ended September 28, 2014, from 27.2% during the 13 weeks ended September 29, 2013, primarily driven by incremental training and shop-level staffing investments, as well as wage inflation in certain states as a result of statutory minimum wage increases.

Occupancy Expenses

Occupancy expenses increased by $1.2 million, or 12.6%, to $10.5 million during the 13 weeks ended September 28, 2014, from $9.3 million during the 13 weeks ended September 29, 2013, primarily due to new shop openings. As a percentage of revenues, occupancy expenses increased to 12.4% during the 13 weeks ended September 28, 2014, from 11.9% during the 13 weeks ended September 29, 2013, due to increased rent as a result of lease extensions in certain legacy markets, as well as increases in other occupancy-related costs.

Other Operating Expenses

Other operating expenses increased by $0.9 million, or 11.3%, to $8.8 million during the 13 weeks ended September 28, 2014, from $7.9 million during the 13 weeks ended September 29, 2013. The increase is attributable to new shop openings and increased fees associated with higher credit card usage in our shops. As a percentage of revenues, other operating expenses increased to 10.4% during the 13 weeks ended September 28, 2014, from 10.2% during the 13 weeks ended September 29, 2013, primarily due to increased utility costs as well as various other operating expenses, partially offset by the $0.2 million cumulative adjustment recorded for the change in accounting estimate related to gift card breakage. Refer to “Critical Accounting Policies and Estimates” for additional information regarding the change in accounting estimate.

General and Administrative Expenses

General and administrative expenses decreased by $0.7 million, or 8.1%, to $7.6 million during the 13 weeks ended September 28, 2014, from $8.3 million during the 13 weeks ended September 29, 2013. The net decrease is driven primarily by lower labor-related costs and lower costs associated with being a public company, including costs associated with our IPO in the prior year, partially offset by costs associated with our plans to move our corporate headquarters. As a percentage of revenues, general and administrative expenses decreased to 9.0% during the 13 weeks ended September 28, 2014, from 10.6% during the 13 weeks ended September 29, 2013, driven by the factors above, coupled with sales leverage (i.e., the ability to spread certain costs over a higher revenue base).

Depreciation Expense

Depreciation expense increased by $0.6 million, or 13.0%, to $5.0 million during the 13 weeks ended September 28, 2014, from $4.5 million during the 13 weeks ended September 29, 2013, primarily due to a higher depreciable base related to new shops and existing shop capital investments. As a percentage of revenues, depreciation increased to 6.0% during the 13 weeks ended September 28, 2014, from 5.7% during the 13 weeks ended September 29, 2013, driven partially from an increase in existing shop capital investments that have, on average, lower useful lives than new shops.

Pre-Opening Costs

Pre-opening costs decreased by $0.1 million, or 13.7%, to $0.3 million during the 13 weeks ended September 28, 2014, from $0.4 million during the 13 weeks ended September 29, 2013, primarily due to fewer new shops opened during the 13 weeks ended September 28, 2014 compared to the 13 weeks ended September 29, 2013.

Impairment and Loss on Disposal of Property and Equipment

Impairment and loss on disposal of property and equipment increased to $1.3 million during the 13 weeks ended September 28, 2014, from $0.3 million during the 13 weeks ended September 29, 2013. After performing a periodic review of our shops during the third quarter of 2014, it was determined that indicators of impairment were present for certain shops as a result of continued underperformance of shop profitability. We performed an impairment analysis related to these shops and recorded an impairment charge of $1.3 million related to the excess of the carrying amounts recorded on our balance sheet over the identified shops’ estimated fair values.

Interest Expense

Interest expense decreased by $55 thousand, or 56.7%, to $42 thousand during the 13 weeks ended September 28, 2014, from $0.1 million during the 13 weeks ended September 29, 2013, primarily due to repaying the $14.0 million outstanding under the senior credit facility on October 24, 2013. Interest expense for the 13 weeks ended September 28, 2014 is attributable to interest on the note payable, unused commitment fees and deferred financing fees.

Income Tax Expense

Income tax expense increased by $0.4 million to $1.3 million for the 13 weeks ended September 28, 2014, from $0.9 million during the 13 weeks ended September 29, 2013. For the 13 weeks ended September 28, 2014, our effective tax rate was 39.2%, compared to 29.4% for the 13 weeks ended September 29, 2013. The increase in the effective tax rate primarily relates to the expiration of certain federal income tax credits that were available in prior years, as well as certain provision to return adjustments recorded in the prior year.

Revenues

Total revenues increased by $17.2 million, or 7.7%, to $242.2 million during the 39 weeks ended September 28, 2014, from $225.0 million during the 39 weeks ended September 29, 2013. The increase in revenues primarily consisted of an increase of $19.2 million in sales from shops not yet in our company-operated comparable store sales base, $0.3 million increase in franchise revenues, partially offset by a $2.3 million, or 1.1%, decrease in company-operated comparable store sales. The decrease in company-operated comparable store sales resulted from a reduction in entrée counts, which were impacted by reduced traffic as well as significantly adverse weather in the first quarter, partially offset by certain menu price increases and menu mix.

Cost of Goods Sold

Cost of goods sold increased by $3.3 million, or 5.0%, to $69.1 million during the 39 weeks ended September 28, 2014, compared to $65.8 million during the 39 weeks ended September 29, 2013, primarily due to the increase in revenues. As a percentage of revenues, cost of goods sold decreased to 28.5% during the 39 weeks ended September 28, 2014, from 29.2% during the 39 weeks ended September 29, 2013, primarily driven by lower commodity costs, certain menu price increases, as well as volume-based rebates from certain vendors.

Labor and Related Expenses

Labor and related expenses increased by $6.4 million, or 10.3%, to $68.6 million during the 39 weeks ended September 28, 2014, from $62.2 million during the 39 weeks ended September 29, 2013, primarily due to new shop openings. As a percentage of revenues, labor and related expenses increased to 28.3% during the 39 weeks ended September 28, 2014, from 27.7% during the 39 weeks ended September 29, 2013, primarily driven by deleveraging of the fixed component of these expenses as a result of lower company-operated comparable store sales, incremental training and shop-level staffing investments, as well as wage inflation in certain states as a result of statutory minimum wage increases.

Occupancy Expenses

Occupancy expenses increased by $3.8 million, or 14.2%, to $30.6 million during the 39 weeks ended September 28, 2014, from $26.8 million during the 39 weeks ended September 29, 2013, primarily due to new shop openings. As a percentage of revenues, occupancy expenses increased to 12.6% during the 39 weeks ended September 28, 2014, from 11.9% during the 39 weeks ended September 29, 2013, due to deleveraging of the fixed component of these expenses as a result of lower company-operated comparable store sales as well as increased rent as a result of lease extensions in certain legacy markets and increases in other occupancy-related costs.

Other Operating Expenses

Other operating expenses increased by $2.6 million, or 11.4%, to $25.7 million during the 39 weeks ended September 28, 2014, from $23.1 million during the 39 weeks ended September 29, 2013, primarily due to costs associated with new shop openings and increased fees associated with higher credit card usage in our shops. As a percentage of revenues, other operating expenses increased to 10.6% during the 39 weeks ended September 28, 2014, from 10.3% during the 39 weeks ended September 29, 2013. These increases are primarily due to deleveraging of the fixed component of these expenses as a result of lower company-operated comparable store sales as well as increased utility costs, partially offset by the $0.2 million cumulative adjustment recorded for the change in accounting estimate related to gift card breakage. Refer to “Critical Accounting Policies and Estimates” for additional information regarding the change in accounting estimate.

General and Administrative Expenses

General and administrative expenses remained consistent at $24.3 million during the 39 weeks ended September 28, 2014 and the 39 weeks ended September 29, 2013. As a percentage of revenues, general and administrative expenses decreased to 10.0% during the 39 weeks ended September 28, 2014, from 10.8% during the 39 weeks ended September 29, 2013, primarily driven by sales leverage (i.e., the ability to spread certain costs over a higher revenue base), lower labor-related expenses and costs associated with being a public company, including costs associated with our IPO in the prior year, offset by an increase in advertising expenses due to approximately $0.4 million related to the launch of the new Flats platform in late May and initial costs associated with our plans to move our corporate headquarters, among other costs.

Depreciation Expense

Depreciation expense increased by $1.2 million, or 9.5%, to $14.5 million during the 39 weeks ended September 28, 2014, from $13.3 million during the 39 weeks ended September 29, 2013, primarily due to a higher depreciable base related to new shops. As a percentage of revenues, depreciation increased to 6.0% during the 39 weeks ended September 28, 2014, from 5.9% during the 39 weeks ended September 29, 2013.

Pre-Opening Costs

Pre-opening costs decreased by $0.3 million, or 22.5%, to $0.8 million during the 39 weeks ended September 28, 2014, from $1.1 million during the 39 weeks ended September 29, 2013, primarily due to fewer new shops opened in new markets that, on average, have higher pre-opening costs during the 39 weeks ended September 28, 2014 compared to the 39 weeks ended September 29, 2013.

Impairment and Loss on Disposal of Property and Equipment

Impairment and loss on disposal of property and equipment increased to $2.2 million during the 39 weeks ended September 28, 2014, from $0.3 million during the 39 weeks ended September 29, 2013. After performing a periodic review of our shops during each fiscal quarter of 2014, it was determined that indicators of impairment were present for certain shops as a result of continued underperformance of shop profitability. We performed an impairment analysis related to these shops and recorded an impairment charge of $2.1 million related to the excess of the carrying amounts recorded on our balance sheet over the identified shops’ estimated fair values.

Interest Expense

Interest expense decreased by $0.2 million, or 62.4%, to $0.1 million during the 39 weeks ended September 28, 2014, from $0.3 million during the 39 weeks ended September 29, 2013, primarily due to repaying the $14.0 million outstanding under the senior credit facility on October 24, 2013. Interest expense for the 13 weeks ended September 28, 2014 is attributable to interest on the note payable, unused commitment fees and deferred financing fees.

Income Tax Expense

Income tax expense decreased by $0.3 million, or 11.3%, to $2.5 million during the 39 weeks ended September 28, 2014, from $2.8 million during the 39 weeks ended September 29, 2013, as a result of lower taxable net income. For the 39 weeks ended September 28, 2014, our effective tax rate was 40.3%, compared to 36.0% for the 39 weeks ended September 29, 2013. The increase in the effective tax rate primarily relates to the expiration of certain federal income tax credits for 2014 that were available in prior years, as well as certain provision to return adjustments recorded in the prior year.

Liquidity and Capital Resources

General

Our primary sources of liquidity and capital resources are cash provided from operating activities, existing cash and cash equivalents and our credit facility. Our primary requirements for liquidity and capital are new shop openings, existing shop capital investments (maintenance and improvements), principal and interest payments on our debt, lease obligations, repurchases of our common stock, working capital and general corporate needs. Our requirement for working capital is not significant since our customers pay for their food and beverage purchases in cash or payment cards (credit or debit) at the time of sale. Thus, we are able to sell certain inventory items before we have to pay our suppliers for such items. Our shops do not require significant inventories or receivables. We believe that these sources of liquidity and capital will be sufficient to finance our continued operations and expansion plans for at least the next twelve months.

The following table presents summary cash flow information for the periods indicated (in thousands):


	For the 39 Weeks Ended
	September 28, 2014			September 29, 2013
Net cash provided by (used in):
Operating activities	$	23,294		$	24,379
Investing activities		(20,544	)		(21,265	)
Financing activities		(2,926	)		(590	)

Net (decrease) increase in cash	$	(176	)	$	2,524

Operating Activities

Net cash provided by operating activities decreased to $23.3 million for the 39 weeks ended September 28, 2014, from $24.4 million for the 39 weeks ended September 29, 2013. The $1.1 million decrease is primarily attributable to a net cash outflow of $1.6 million related to a vendor prepayment with no comparable prepayment made in the 39 weeks ended September 29, 2013, as well as $0.2 million of various net working capital changes. This was offset by a net cash inflow of $0.7 million related to increased net income before adjustments for interest, income taxes, depreciation and amortization and impairment/disposal of long-lived assets.

Investing Activities

Net cash used in investing activities decreased to $20.5 million for the 39 weeks ended September 28, 2014, from $21.3 million for the 39 weeks ended September 29, 2013. The decrease was primarily due to two fewer company-operated shop openings during the 39 weeks ended September 28, 2014 as compared to the same period in 2013 and partially offset by an increase in existing shop capital investments during the 39 weeks ended September 28, 2014 as compared to the same period in 2013.

Financing Activities

Net cash used in financing activities was $2.9 million for the 39 weeks ended September 28, 2014, as compared to $0.6 million for the 39 weeks ended September 29, 2013. The increase in net cash used was driven by the $5.8 million of treasury stock repurchased during the 39 weeks ended September 28, 2014, with no comparable transactions during the 39 weeks ended September 29, 2013, offset by $3.0 million in cash proceeds received by us related to the exercise of stock options, net of payroll taxes paid, during the 39 weeks ended September 28, 2014, with no comparable cash proceeds received during the 39 weeks ended September 29, 2013.

Stock Repurchase Program

On August 1, 2014, our Board of Directors authorized a share repurchase program of up to $35.0 million of the Company’s common stock. Under this program, we may, from time to time, purchase shares in the open market (including in pre-arranged stock trading plans in accordance with the guidelines specified in Rule 10b5-1 under the Exchange Act) or in privately negotiated transactions. During the 13 weeks ended September 28, 2014, we repurchased 471,290 shares of common stock for approximately $5.8 million in open market transactions. At September 28, 2014, the remaining dollar value of authorization under the share repurchase program was $29.2 million.

Credit Facility

On September 21, 2012, we entered into a five-year revolving credit facility agreement with JPMorgan Chase Bank, N.A. that expires in September 2017 and provides for borrowings up to $35.0 million to fund capital expenditures for new shops, renovations and maintenance of existing shops, and to provide ongoing working capital for other general and corporate purposes. We will be entitled to incur additional incremental increases in the revolving credit facility of up to $25.0 million that will be included in the credit facility if no event of default exists and certain other requirements are met. The credit facility contains customary representations, warranties, negative and affirmative covenants, including a requirement to maintain a maximum leverage ratio, as defined, of 2.25:1 and a minimum debt service coverage ratio, as defined, of 1.5:1. The credit facility also limits the restricted payments (primarily distributions and equity repurchases) that we may make, unless we obtain certain waivers or amendments from our lender. We were in compliance with these restrictions and conditions as of September 28, 2014. The credit facility is secured by substantially all assets of the Company. Borrowings under the credit facility bear interest at our option at either (i) a Eurocurrency rate determined by reference to the applicable LIBOR rate plus an applicable margin or (ii) a prime rate as announced by JPMorgan Chase plus an applicable margin. As of September 28, 2014, we had no amounts outstanding under the credit facility.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Critical accounting policies are those that management believes are both most important to the portrayal of our financial condition and operating results, and require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. We base our estimates on historical experience and other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Judgments and uncertainties affecting the application of those policies may result in materially different amounts being reported under different conditions or using different assumptions. We had no significant changes in our critical accounting estimates since our last annual report. Our critical accounting estimates are identified and described in our annual consolidated financial statements and related notes.

Revenues from our gift cards are deferred and were previously recognized upon redemption or after a period of 36 months of inactivity on gift card balances (“gift card breakage”) and we do not have a legal obligation to remit the value of the unredeemed gift cards to the relevant jurisdictions. We monitor our actual patterns of redemption and update our estimates and assumptions regarding redemption as the actual pattern changes. We estimate and record gift card breakage income based on our historical redemption pattern. During the third fiscal quarter of 2014, we updated our analysis of historical gift card redemptions based on approximately three years of historical data and changed our estimate to record gift card breakage income from 36 months to 24 months after the date of issuance for all gift cards that have not been redeemed. In accordance with ASC 250, “Accounting Changes and Error Corrections,” we recorded a cumulative adjustment of $0.2 million, which is included in other operating expenses, representing the effect of this change in accounting estimate.

Off-Balance Sheet Arrangements

As of September 28, 2014, we do not have any off-balance sheet arrangements, synthetic leases, investments in special purpose entities or undisclosed borrowings or debt that would be required to be disclosed pursuant to Item 303 of Regulation S-K under the Exchange Act.

New and Revised Financial Accounting Standards

We qualify as an “emerging growth company” pursuant to the provisions of the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, enacted on April 5, 2012. Section 102 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. However, we are choosing to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Our decision to opt out of the extended transition period is irrevocable.

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers.” The pronouncement was issued to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and IFRS. The pronouncement is effective for reporting period beginning after December 15, 2016. The adoption of ASU 2014-09 is not expected to have a significant impact on the Company’s consolidated balance sheet or consolidated statement of operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

For quantitative and qualitative disclosures about market risk, see Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” of our Annual Report on Form 10-K for the fiscal year ended December 29, 2013. Our exposures to market risk have not changed materially since December 29, 2013.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 28, 2014. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 28, 2014, our disclosure controls and procedures were effective in ensuring that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There have been no changes in our internal control over financial reporting that occurred during our fiscal quarter ended September 28, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits 31.1 and 31.2 to this Quarterly Report on Form 10-Q.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We are subject to legal proceedings, claims and liabilities, such as employment-related claims and slip and fall cases, which arise in the ordinary course of business and are generally covered by insurance. In the opinion of management, the amount of ultimate liability with respect to those actions should not have a material adverse impact on our financial position or results of operations and cash flows.

ITEM 1A. RISK FACTORS

A description of the risk factors associated with our business is contained in Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 29, 2013. There have been no material changes to our Risk Factors as previously reported.

<div> Basis of Presentation The unaudited condensed consolidated financial statements and notes herein should be read in conjunction with the audited consolidated financial statements of Potbelly Corporation and its subsidiaries and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 29, 2013. The unaudited condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. In the opinion of management, all adjustments, which are of a normal and recurring nature (except as otherwise noted), that are necessary to present fairly the Company’s financial position as of December 29, 2013 and September 28, 2014, its statement of operations for the 13 and 39 weeks ended September 29, 2013 and September 28, 2014 and its statement of cash flows for the 39 weeks ended September 29, 2013 and September 28, 2014 have been included. The consolidated statements of operations for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year. The Company does not have any components of other comprehensive income (loss) recorded within its consolidated financial statements, and, therefore, does not separately present a statement of comprehensive income (loss) in its consolidated financial statements. </div>

For the 13 and 39 weeks ended September 29, 2013, diluted (loss) per common share attributable to common stockholders was computed by dividing the (loss) allocated to common stockholders utilizing the two-class method by the weighted average number of fully diluted common shares outstanding. In periods with net income attributable to common stockholders, the Company’s redeemable convertible preferred stock were all considered participating securities requiring the two-class method to calculate basic and diluted earnings per share. However, in periods of a net (loss) attributable to common stockholders, the redeemable convertible preferred stock were excluded from the computation of basic earnings per share due to the fact that they were not required to fund losses and the redemption amount was not reduced as a result of losses. For the 13 and 39 weeks ended September 29, 2013, the dilutive securities did not include stock options awarded to employees that had a performance condition requiring the completion of an initial public offering of common stock, as that performance condition was not satisfied at the reporting date and the holders of these options had no rights in our undistributed earnings until that time. On October 9, 2013, the Company completed an initial public offering. Effective upon the closing of such offering, all of the shares of preferred stock and non-voting common stock converted into common stock. As a result of the conversion, for subsequent reporting periods, the Company no longer utilized the two-class method in its calculation of diluted income (loss) per common share attributable to common stockholders. For the 13 and 39 weeks ended September 28, 2014, diluted income (loss) per common share attributable to common stockholders was calculated using income available to common shareholders divided by diluted weighted-average shares of common stock outstanding during the period. <p style="MARGIN-BOTTOM: 0px;

<div> Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions, primarily related to long-lived assets, income taxes, stock-based compensation and common stock equity valuations, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. </div>

<div> (6) Stock-Based Compensation  Throughout the 39 weeks ending September 28, 2014, the Company issued 292,767 stock options under the 2013 Long-Term Incentive Plan to eligible employees and key executives. The fair value of the options was determined using the Black-Scholes option pricing model. The weighted average common stock fair value of options granted during the 39 weeks ended September 28, 2014 was $19.58 per share, as estimated using the following weighted average assumptions: expected life of options – seven years; volatility- 49.36%; risk-free interest rate – 1.28%; and dividend yield – 0.00%. The Company used the simplified method for determining the expected life of the options. Due to the lack of historical data as a newly public company, the Company calculated the specific stock price volatility using a blended volatility rate based on comparable publicly traded companies. A summary of activity for the 39 weeks ended September 28, 2014 is as follows:   <table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; BORDER-COLLAPSE: collapse" cellspacing="0" cellpadding="0" width="92%" align="center" border="0"> <tr> <td width="65%"></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td valign="bottom" width="4%"></td> <td></td> <td></td> <td></td> </tr> <tr style="FONT-SIZE: 8pt;

The unrestricted stock had a weighted average grant-date share price of $15.29 upon issuance. The Company recorded $0.4 million in stock-based compensation expense, with a corresponding increase to additional paid-in capital, related to the issuance of common stock. In accordance with ASC Topic 718, Compensation—Stock Compensation, stock-based compensation is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the requisite employee service period, which is generally the vesting period of the grant, with a corresponding increase to additional paid-in-capital. For the 13 and 39 weeks ended September 28, 2014, the Company recognized stock-based compensation expense of $0.6 million and $2.0 million, respectively, which includes $32 thousand and $0.4 million related to the unrestricted common stock granted during 2014, respectively. For the 13 and 39 weeks ended September 29, 2013, the Company recognized stock-based compensation expense of $1.2 million and $2.4 million, respectively. As of September 28, 2014, the unrecognized stock-based compensation expense was $6.0 million, which will be recognized through fiscal year 2018. The Company records stock-based compensation expense within general and administrative expenses in the consolidated statements of operations. </div>

Shop-level assets are grouped at the individual shop-level for the purpose of the impairment assessment. Recoverability of an asset is measured by a comparison of the carrying amount of an asset to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. The fair value of the shop assets was determined using the discounted future cash flow method of anticipated cash flows through the shop’s lease-end date using fair value measurement inputs classified as Level 3. Level 3 inputs are derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. After performing a periodic review of our shops during each quarter of 2014, it was determined that indicators of impairment were present for certain shops as a result of continued underperformance of shop profitability. We performed an impairment analysis related to these shops and recorded impairment charges of $1.3 million and $2.1 million for the 13 and 39 weeks ended September 28, 2014, respectively, related to the excess of the carrying amounts recorded on our balance sheet over the identified shops’ estimated fair values. <p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px"> In the third fiscal quarter of 2014, the Company established a non-qualified deferred compensation plan, “Potbelly Non-Qualified Deferred Compensation Plan,” which allows highly compensated employees to defer a portion of their base salary and variable compensation each plan year. The Company maintains a rabbi trust to fund obligations under the deferred compensation plan. Amounts in the rabbi trust are invested in mutual funds. The investments in the rabbi trust are designated as trading securities and carried at fair value. Fair market value of investments in the rabbi trust is measured using Level 1 inputs (quoted prices for identical assets in active markets). As of September 28, 2014, the fair value of the investments in the rabbi trust was $16 thousand, which is included in other assets in the condensed consolidated balance sheet. The Company records trading gains and losses in general and administrative expenses in the condensed consolidated statement of operations, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect its exposure to liabilities for payment under the deferred plan. For the three months ended September 28, 2014, the Company recorded an immaterial amount of unrealized losses on investments held in the rabbi trust. </div>

Fair Value Measurements	Sep. 28, 2014
Fair Value Disclosures [Abstract]
Fair Value Measurements	(2) Fair Value Measurements The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and all other current liabilities approximate fair values due to the short maturities of these balances. The Company assesses potential impairments to its long-lived assets, which includes property and equipment, whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. Shop-level assets are grouped at the individual shop-level for the purpose of the impairment assessment. Recoverability of an asset is measured by a comparison of the carrying amount of an asset to its estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset group exceeds its estimated undiscounted future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. The fair value of the shop assets was determined using the discounted future cash flow method of anticipated cash flows through the shop’s lease-end date using fair value measurement inputs classified as Level 3. Level 3 inputs are derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. After performing a periodic review of our shops during each quarter of 2014, it was determined that indicators of impairment were present for certain shops as a result of continued underperformance of shop profitability. We performed an impairment analysis related to these shops and recorded impairment charges of $1.3 million and $2.1 million for the 13 and 39 weeks ended September 28, 2014, respectively, related to the excess of the carrying amounts recorded on our balance sheet over the identified shops’ estimated fair values. In the third fiscal quarter of 2014, the Company established a non-qualified deferred compensation plan, “Potbelly Non-Qualified Deferred Compensation Plan,” which allows highly compensated employees to defer a portion of their base salary and variable compensation each plan year. The Company maintains a rabbi trust to fund obligations under the deferred compensation plan. Amounts in the rabbi trust are invested in mutual funds. The investments in the rabbi trust are designated as trading securities and carried at fair value. Fair market value of investments in the rabbi trust is measured using Level 1 inputs (quoted prices for identical assets in active markets). As of September 28, 2014, the fair value of the investments in the rabbi trust was $16 thousand, which is included in other assets in the condensed consolidated balance sheet. The Company records trading gains and losses in general and administrative expenses in the condensed consolidated statement of operations, along with the offsetting amount related to the increase or decrease in deferred compensation to reflect its exposure to liabilities for payment under the deferred plan. For the three months ended September 28, 2014, the Company recorded an immaterial amount of unrealized losses on investments held in the rabbi trust.

The unaudited condensed consolidated financial statements included herein have been prepared by the Company without audit, pursuant to the rules and regulations of the SEC regarding interim financial reporting. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the SEC’s rules and regulations. In the opinion of management, all adjustments, which are of a normal and recurring nature (except as otherwise noted), that are necessary to present fairly the Company’s financial position as of December 29, 2013 and September 28, 2014, its statement of operations for the 13 and 39 weeks ended September 29, 2013 and September 28, 2014 and its statement of cash flows for the 39 weeks ended September 29, 2013 and September 28, 2014 have been included. The consolidated statements of operations for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year. The Company does not have any components of other comprehensive income (loss) recorded within its consolidated financial statements, and, therefore, does not separately present a statement of comprehensive income (loss) in its consolidated financial statements. *Principles of Consolidation* The unaudited condensed consolidated financial statements include the accounts of Potbelly Corporation; its wholly owned subsidiary, Potbelly Illinois, Inc. (“PII”); PII’s wholly owned subsidiaries, Potbelly Franchising, LLC, Potbelly Sandwich Works, LLC (“LLC”) and 16 of LLC’s wholly owned subsidiaries and the LLC’s two joint ventures, collectively, the “Company.” All significant intercompany balances and transactions have been eliminated in consolidation. For the Company’s consolidated joint ventures, non-controlling interest represents the non-controlling partners’ share of the assets, liabilities and operations related to their respective joint venture investments. The Company has ownership interests ranging from 65-75% in these consolidated joint ventures. *Use of Estimates* The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions, primarily related to long-lived assets, income taxes, stock-based compensation and common stock equity valuations, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. *Fiscal Year* The Company uses a 52/53-week fiscal year that ends on the last Sunday of the calendar year. Approximately every five or six years a 53rd week is added. Fiscal 2013 and 2014 each consist of 52 weeks. The fiscal quarters ended September 29, 2013 and September 28, 2014 each consisted of 13 weeks.

Capital Stock	(5) Capital Stock On October 9, 2013, the Company completed an initial public offering. Effective upon the closing of such offering, all shares of preferred stock and non-voting common stock converted into common stock. The terms of the non-voting common stock provided that all shares of non-voting common stock would convert into voting common stock on a 1:1 basis immediately prior to the closing of an underwritten IPO or sale of the Company. The redeemable convertible preferred stock included down-round provisions which would adjust the conversion price for any additional stock issued without consideration or for a consideration per share less than the respective conversion price for one or more of the series of preferred stock in effect immediately prior to the issuance of such additional stock. Each share of common stock has the same relative rights and was identical in all respects to each other share of common stock. Each holder of shares of common stock is entitled to one vote for each share held by such holder at all meetings of stockholders. On August 1, 2014, the Company’s Board of Directors authorized a share repurchase program of up to $35.0 million of the Company’s common stock. Under this program, the Company may, from time to time, purchase shares in the open market (including in 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. During the 13 weeks ended September 28, 2014, the Company repurchased 471,290 shares of its common stock for approximately $5.8 million in open market transactions. As of September 28, 2014, the remaining dollar value of authorization under the share repurchase program was $29.2 million. Repurchased shares are included as treasury stock in the Condensed Consolidated Balance Sheets and the Condensed Consolidated Statements of Redeemable Convertible Preferred Stock and Equity.

Income Tax Disclosure [Abstract]
Income Taxes	(4) Income Taxes The Company recognized income tax expense of $2.5 million on pre-tax income of $6.1 million, or an effective tax rate of 40.3%, for the 39 weeks ended September 28, 2014, compared to income tax expense of $2.8 million on pre-tax income of $7.8 million or an effective tax rate of 36.0%, for the 39 weeks ended September 29, 2013. The difference between the statutory rate and the effective tax rate is primarily attributable to state income taxes offset by certain federal and state tax credits. The increase in the effective tax rate primarily relates to the expiration of certain federal income tax credits for 2014 that were available in prior years as well as provision to return adjustments.
