Providence, Rhode Island — September 11, 2012 — United Natural Foods, Inc. (Nasdaq: UNFI) (the “Company”) today reported net sales for the fourth quarter of fiscal 2012 ended July 28, 2012 of $1.34 billion, an increase of 16.0%, or $185.0 million, compared with $1.16 billion for the comparable quarter in fiscal 2011.

Net income for the fourth quarter of fiscal 2012 increased by $8.0 million, or 46.4%, to $25.1 million compared with $17.2 million for the comparable quarter in fiscal 2011.  This was primarily due to improvements in our operational efficiency, as well as pre-tax expenses of $6.3 million recognized during the fourth quarter of fiscal 2011 in connection with the restructuring of the Company’s UNFI Specialty Distribution Services division (“UNFI Specialty”), including the impairment of the Company’s Harrison, Arkansas facility and other expenses incurred in connection with the divestiture of the Company’s general merchandise and conventional non-food lines of business (collectively the “restructuring expenses”).  Excluding the restructuring expenses recognized in the fourth quarter of fiscal 2011, net income for the fourth quarter of fiscal 2012 increased by $4.2 million, or 20.1%, to $25.1 million, from $20.9 million for the comparable fiscal 2011 period.  Earnings per diluted share for the fourth quarter of fiscal 2012 were $0.51, compared with $0.35 in the prior fiscal year comparable period.  Earnings per diluted share for the fourth quarter of fiscal 2012 rose 18.6% to $0.51, from $0.43 per diluted share for the fourth quarter of fiscal 2011 excluding the restructuring expenses recognized in that period.

Gross margin was 17.2% for the fourth quarter of fiscal 2012, representing a 41 basis point sequential decline from the gross margin of 17.6% for the third quarter of fiscal 2012.  The lower gross margin was due to purchasing and logistics inefficiencies experienced in the fourth quarter of fiscal 2012, and to a lesser extent, the

continued shift in the Company’s customer mix to lower margin conventional supermarkets and lower fuel surcharge revenues.  Gross margin for the fourth quarter of fiscal 2012 was 137 basis points lower than the prior year’s comparable quarter, primarily attributable to the continued shift in UNFI’s customer mix, as well as the lower fuel surcharge revenues in the fourth quarter of fiscal 2012.

Operating expenses as a percentage of net sales for the fiscal 2012 fourth quarter decreased to 14.0% from 16.0% for the prior year comparable period, in part as a result of the $6.3 million of pre-tax restructuring expenses recognized during the fiscal 2011 fourth quarter.  Operating expenses as a percentage of net sales for the fourth quarter of fiscal 2012 decreased 150 basis points compared with the fiscal 2011 fourth quarter after excluding restructuring expenses recognized in that quarter.  Operating income as a percentage of net sales was 3.2% for the fiscal 2012 fourth quarter, compared with 2.5% in the prior year comparable quarter.  Operating income as a percentage of net sales for the fourth quarter of fiscal 2012 increased 12 basis points compared with the fiscal 2011 fourth quarter after excluding restructuring expenses recognized in that quarter.

The following table details the amounts and effect of the restructuring expenses and the reconciliation of pre-tax income and net income, excluding this special item (Non-GAAP basis), to pre-tax income and net income, including this special item (GAAP basis) for the fourth quarter of fiscal 2011 ended July 30, 2011:

All Non-GAAP numbers for the fourth quarter of fiscal 2011 have been adjusted to exclude this special item.  A description of the Company’s use of Non-GAAP information is provided under “Non-GAAP Financial Measures” below.

Fiscal Year 2012 Summary

Net sales for fiscal 2012 totaled $5.24 billion, a 15.6% increase over the prior fiscal year.  Diluted earnings per share were $1.86 for fiscal 2012, a 16.3% increase over $1.60 per diluted share for fiscal 2011.  Excluding the restructuring expenses that were recognized in both periods and the expenses recognized in fiscal 2012 related to the onboarding of a national customer (the “onboarding expenses”), earnings per diluted share were $1.94 for fiscal 2012, a 15.5% increase over fiscal 2011 earnings per diluted share of $1.68.  Earnings per diluted share for fiscal 2012 also included the additional dilutive effect of the Company’s common stock offering of 4.43 million new shares completed in the first quarter of fiscal 2011.

Gross margin at 17.5% of net sales for fiscal 2012 was 72 basis points lower in fiscal 2012 than fiscal 2011, primarily as a result of the continued shift in customer mix.  Total operating expenses as a percentage of net sales for fiscal 2012 were 14.5%, compared with 15.3% for the prior fiscal year.  Excluding the restructuring expenses that were recognized in each period and the onboarding expenses recognized in fiscal 2012, total operating expenses were 14.4% of net sales for fiscal 2012, 81 basis points lower than the prior fiscal year.  Operating income for fiscal 2012 increased by $25.5 million, or 19.7%, over fiscal 2011 to $155.2 million, resulting in an operating margin of 3.0%.  Excluding the restructuring expenses that were recognized in each period and the onboarding expenses recognized in fiscal 2012, operating income increased $25.9 million, or 19.0% over fiscal 2011 to $161.8 million for fiscal 2012, resulting in an operating margin of 3.1% as a percentage of net sales.

“Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995: Statements in this press release regarding the Company’s business that are not historical facts are “forward-looking statements” that involve risks and uncertainties and are based on current expectations and management estimates; actual results may differ materially. The risks and uncertainties which could impact these statements are described in the Company’s filings under the Securities Exchange Act of 1934, as amended, including its annual report on Form 10-K filed with the Securities and Exchange Commission on September 28, 2011 and other filings the Company makes with the SEC, and include, but are not limited to, the Company’s dependence on principal customers; the Company’s sensitivity to general economic conditions, including the current economic environment; changes in disposable income levels and consumer spending trends; the Company’s ability to reduce its operating expenses in amounts sufficient to offset its increased focus on sales to conventional supermarkets and the resulting lower gross margins on these sales; the Company’s ability to timely and successfully deploy its new warehouse management system throughout its distribution centers; increased fuel costs; the Company’s sensitivity to inflationary and deflationary pressures; the relatively low margins and economic sensitivity of the Company’s business; the ability to identify and successfully complete acquisitions of other natural, organic and specialty food and related product distributors; and management’s allocation of capital and the timing of capital expenditures. Any forward-looking statements are made pursuant to the Private Securities Litigation Reform Act of 1995 and, as such, speak only as of the date made. The Company is not undertaking to update any information in the foregoing reports until the effective date of its future reports required by applicable laws.

Non-GAAP Financial Measures:  To supplement its financial statements presented on a generally accepted accounting principles (“GAAP”) basis, the Company has included in this press release non-GAAP financial measures (including operating expenses, operating income, net income and diluted earnings per share) which, in each case exclude expenses associated with the restructuring and divestiture of the Company’s general merchandise and conventional non-foods lines of business and the start-up costs associated with the onboarding of a national customer.  The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for any measure prepared in accordance with GAAP. The Company believes that presenting its operating expenses, operating income, net income and diluted earnings per share for the fiscal year ended July 28, 2012 excluding the restructuring expenses and onboarding expenses facilitates making period-to-period comparisons and is a meaningful indication of its operating performance. The Company’s management utilizes this non-GAAP financial information to compare the Company’s operating performance during the 2012 fiscal year versus the comparable periods in the 2011 fiscal year and its operating performance projected for the 2013 fiscal year to the 2012 fiscal year performance, as well as to internally prepared projections.
