Roundy’s, Inc. Reports First Quarter 2015 Financial Results

MILWAUKEE – May 13, 2015 – Roundy’s, Inc. (“Roundy’s”) (NYSE: RNDY), a leading grocer in the Midwest, today reported financial results for the first quarter ended April 4, 2015.

Q1 2015¹

“We achieved our targeted EBITDA and gross margin rate for the first quarter, which were the result of improved operational efficiencies in both our Wisconsin and Illinois stores. Due to softer than anticipated March and Easter sales, our same-store sales were below our expectations,” said Robert A. Mariano, chairman, president and chief executive officer of Roundy’s. “We remain committed to improving financial performance across all of our banners. Our team has embarked on a number of initiatives aimed at managing expenses and further improving our operating efficiencies and execution.”

Financial Results for First Quarter of 2015

Results from Continuing Operations

Net sales from continuing operations for the first quarter of 2015 were $981.9 million, an increase of $119.2 million, or 13.8%, from $862.7 million for the first quarter of 2014. Same-store sales from continuing operations declined 1.6%, which was due to a 1.9% decrease in the number of customer transactions, partially offset by a 0.3% increase in average transaction size. Adjusted for the effect of the 2015 Easter holiday calendar shift, same-store sales declined 2.9%.

Net sales for the Company’s Wisconsin markets were $646.7 million for the first quarter 2015, a decrease of $16.8 million, or 2.5% from $663.5 million for the first quarter 2014. The decrease primarily reflects the closure of three stores during the fourth quarter of 2014. Same-store sales decreased 0.1%, due to a 0.8% decrease in the number of customer transactions, partially offset by a 0.7% increase in the average transaction

size. Same-store sales were positively impacted by the Easter holiday calendar shift from the second quarter of 2014 into the first quarter of 2015. Adjusted for the effect of the 2015 Easter holiday calendar shift, same-store sales declined 1.4%. Same-store sales in the Company’s Wisconsin markets continue to be negatively impacted by competitive store openings.

Net sales for the Company’s Illinois market were $335.2 million for the first quarter 2015, an increase of $136.0 million, or 68.2% from $199.2 million for the first quarter 2014. The increase primarily reflects the benefit of new and acquired stores in Illinois, partially offset by a 6.4% decrease in same-store sales. The decrease in same-store sales was due to a 5.5% decrease in the number of customer transactions and a 0.9% decrease in the average transaction size. Same-store sales were positively impacted by the Easter holiday calendar shift from the second quarter of 2014 into the first quarter of 2015. Adjusted for the effect of the 2015 Easter holiday calendar shift, same-store sales declined 7.7%. Same-store sales were negatively impacted by the cannibalization effect of new and acquired store openings in the Illinois market. In addition, same-store sales have been negatively impacted by the reopening of a significant number of former Dominick’s stores that were initially closed in early 2014 and are now operated by other competitors.

Gross profit for the first quarter of 2015 increased 13.5% to $261.6 million, from $230.5 million in the same period last year. Gross profit as a percentage of net sales was 26.6% for the first quarter of 2015, compared to 26.7% in the same period last year. The decrease in gross profit as a percentage of net sales primarily reflects increased shrink, partially offset by an increased perishable sales mix.

Operating and administrative expenses for the first quarter of 2015 increased to $248.8 million, from $218.1 million in the same period last year. Operating and administrative expenses as a percentage of net sales were 25.3% in the first quarter of 2015 and 2014, respectively.

For the first quarter of 2015, net loss from continuing operations was $0.4 million, or $0.01 diluted net loss per common share, compared to net loss from continuing operations of $5.5 million, or $0.12 diluted net loss per common share, for the first quarter of 2014. Adjusted net loss from continuing operations for the first quarter of 2015 was $0.4 million, or $0.01 adjusted diluted net loss per common share, compared to adjusted net loss from continuing operations of $0.8 million, or $0.02 adjusted diluted net loss per common share, for the first quarter of 2014. See “Reconciliation of Non-GAAP Amounts” for important information about Adjusted Net Loss from Continuing Operations and Adjusted Net Loss Per Common Share from Continuing Operations, which are non-GAAP financial measures, and for a full reconciliation of the most comparable GAAP measures.

Adjusted EBITDA from continuing operations for the first quarter of 2015 was $30.2 million, compared to $28.5 million in the first quarter of 2014. The increase primarily reflects the benefit of the 2015 Easter holiday shift.

Net cash flows used in operating activities for the thirteen weeks ended April 4, 2015 were $5.4 million, compared to $13.7 million for the thirteen weeks ended March 29, 2014. The decrease in cash used by operating activities was due primarily to a decrease in accounts receivable and prepaid expenses and lower payments for interest and taxes.

Discontinued Operations

During the second quarter of 2014, the Company entered into definitive agreements to sell 18 Rainbow stores in the Minneapolis / St. Paul market to a group of local grocery retailers, including SUPERVALU INC. (“Rainbow Store Sale”). The Rainbow Store Sale closed during the third quarter of 2014. The remaining nine Rainbow stores which were not included in the Rainbow Store Sale were closed during the third quarter of 2014 as the Company exited the Minneapolis / St. Paul market entirely. The 27 Rainbow stores are included in discontinued operations in the Consolidated Statements of Comprehensive Loss for the thirteen weeks ended March 29, 2014 and April 4, 2015, respectively.

Adjusted Net Loss from Continuing Operations and Adjusted Net Loss Per Common Share from Continuing Operations (Unaudited)

The following is a summary of the calculation of Adjusted Net Loss from Continuing Operations and Adjusted Net Loss Per Common Share from Continuing Operations for the thirteen weeks ended March 29, 2014 and April 4, 2015 (in thousands, except per share amounts):

The Company presents Adjusted Net Loss and Adjusted Net Loss Per Common Share, non-GAAP measures, to provide investors with a view of operating performance excluding significant and non-recurring items.

7

Adjusted EBITDA (Unaudited)

The following is a summary of the calculation of Adjusted EBITDA for the thirteen weeks ended March 29, 2014 and April 4, 2015 (in thousands):

The Company presents Adjusted EBITDA, a non GAAP measure, to provide investors with a supplemental measure of its operating performance. The Company believes that Adjusted EBITDA is a useful performance measure and is used by the Company to facilitate a comparison of its operating performance on a consistent basis from period-to-period and to provide for a more complete understanding of factors and trends affecting the Company’s business than measures under U.S. generally accepted accounting principles (‘‘GAAP’’) can provide alone. The Company’s board of directors and management also use Adjusted EBITDA as one of the primary methods for planning and forecasting overall expected performance and for evaluating on a quarterly and annual basis actual results against such expectations, and as a performance evaluation metric in determining achievement of certain compensation programs and plans for employees, including its senior executives.

The Company defines Adjusted EBITDA as earnings before interest expense, provision for income taxes, depreciation and amortization, LIFO charges, amortization of deferred financing costs, non-cash compensation expenses arising from the issuance of stock, costs incurred in connection with the Company’s IPO (or subsequent offerings of Roundy’s common stock), loss on debt extinguishment, certain non-recurring or unusual employee and pension related costs, costs related to acquisitions, costs related to debt financing activities, goodwill and asset impairment charges, gain or loss on the disposition of assets, one-time charges due to the closing of stores or a distribution facility, non-recurring gains or losses on lease terminations and Adjusted EBITDA from discontinued operations. Omitting interest, taxes and the other items provides a financial measure that facilitates comparisons of the Company’s results of operations with those of companies having different capital structures. Since the levels of indebtedness, tax structures, and methodologies in calculating LIFO expense that other companies have are different from the Company’s, it omits these amounts to facilitate investors’ ability to make these comparisons. Similarly, the Company omits depreciation and amortization because other companies may employ a greater or lesser amount of owned property, and because in the Company’s experience, whether a store is new or one that is fully or mostly

8

depreciated does not necessarily correlate to the contribution that such store makes to operating performance. The Company believes that investors, analysts and other interested parties consider Adjusted EBITDA an important measure of the Company’s operating performance. Adjusted EBITDA should not be considered as an alternative to net income as a measure of the Company’s performance. Other companies in the Company’s industry may calculate Adjusted EBITDA differently than the Company does, limiting its usefulness as a comparative measure.

Adjusted EBITDA has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of the Company’s results as reported under GAAP. The limitations of Adjusted EBITDA include: (i) it does not reflect the Company’s cash expenditures or future requirements for capital expenditures or contractual commitments; (ii) it does not reflect changes in, or cash requirements for, the Company’s working capital needs; (iii) it does not reflect income tax payments the Company may be required to make; and (iv) although depreciation and amortization are non-cash charges, the assets being depreciated and amortized often will have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.
