Providence, Rhode Island — June 5, 2012 — United Natural Foods, Inc. (Nasdaq: UNFI) today reported net sales for the third quarter of fiscal 2012 ended April 28, 2012 of $1.39 billion, a $184.0 million, or 15.3%, increase compared with net sales of $1.20 billion recorded in the third quarter of fiscal 2011.

“Continued demand for UNFI’s products and services drove our 15.3% net sales growth during the fiscal third quarter,” said Steven Spinner, UNFI’s President and Chief Executive Officer. “Our results demonstrate UNFI’s continued commitment to growing at a rate that exceeds the industry while delivering exemplary customer service to the organic and specialty foods retailer.”

Gross margin was 17.6% for the third quarter of fiscal 2012, representing a 53 basis point decline from gross margin of 18.2% for the prior year comparable period.  Gross margin for the third quarter of fiscal 2012 was impacted primarily by the continued shift in customer mix to the conventional supermarket channel.

Total operating expenses as a percentage of net sales were 14.1% for the third quarter of fiscal 2012, a decrease of 81 basis points compared with the third quarter of fiscal 2011.  This improvement was driven by UNFI’s ongoing initiatives to enhance productivity throughout the organization and reduce operating expenses as a percentage of net sales.  Total operating expenses increased by $16.3 million, or 9.0%, to $195.9 million compared with the third quarter of fiscal 2011, which had operating expenses of $179.6 million.

Operating income as a percentage of net sales increased 27 basis points to 3.5% for the third quarter of fiscal 2012 compared with the third quarter of fiscal 2011.  Net income for the third quarter of fiscal 2012 increased by $5.7 million, or 24.3%, to $29.0 million or $0.59 per diluted share, from $23.4 million, or $0.48 per diluted share, for the third quarter of fiscal 2011.

“Our associates’ continued efforts towards productivity improvements combined with our strong sales volume contributed to our operating margin expansion in the quarter,” added Mr. Spinner. “We believe our year to date

results have left us in a solid position to achieve our operating result targets for fiscal 2012, which supports our revised fiscal 2012 guidance.”

Fiscal 2012 Year to Date Summary

Net sales for the nine months ended April 28, 2012 totaled $3.89 billion, a 15.5% increase over the comparable prior fiscal year period.  Gross margin was 49 basis points less than the comparable prior year period, at 17.6% of net sales for the nine months ended April 28, 2012.

At 14.7% of net sales, total operating expenses for the nine months ended April 28, 2012 were 39 basis points lower than the comparable prior year period.  Operating expenses for the nine months ended April 28, 2012 include approximately $6.9 million of expenses related to the previously announced restructuring and divestiture of the Company’s conventional non-foods and general merchandise lines of business and onboarding expenses related to the Company’s newest national customer.  Excluding these expenses, operating expenses as a percentage of net sales were 14.5% for the nine months ended April 28, 2012, a decrease of 57 basis points compared with the first nine months of fiscal 2011.

Operating income as a percentage of net sales was 2.9% for the nine months ended April 28, 2012, compared to 3.0% for the same period in fiscal 2011.  Excluding the approximately $6.9 million of restructuring and onboarding expenses noted above, operating income as a percentage of net sales was 3.1% for the first nine months of fiscal 2012, an increase of 8 basis points compared with the same period in fiscal 2011.

Updated Fiscal 2012 Guidance

Based on UNFI’s fiscal 2012 performance to date and the current outlook for the remainder of the 2012 fiscal year, the Company is raising its net sales guidance for fiscal year 2012, ending July 28, 2012, to a range of $5.18 billion to $5.22 billion, which represents a 14.3% to 15.3% increase in total net sales over fiscal 2011.  On

March 6, 2012, the Company previously provided fiscal 2012 net sales guidance of a range of $5.11 billion to $5.17 billion, an increase of approximately 12.8% to 14.1% over fiscal 2011, respectively.

The Company is narrowing and raising its GAAP diluted earnings per share guidance for fiscal 2012 to a range of approximately $1.84 to $1.88.  This reflects the impact of sales trends and anticipated leverage in operating efficiencies.  UNFI previously provided, on March 6, 2012, GAAP earnings guidance of $1.79 to $1.86 per diluted share.  The Company expects to incur approximately $6.8 million to $7.0 million in operating expenses associated with its previously announced divestiture of conventional non-foods and general merchandise lines of business and the start-up expenses associated with the on-boarding of a new national customer during fiscal 2012. Excluding the impact of these expenses, UNFI expects diluted earnings per share for fiscal 2012 in the range of approximately $1.92 to $1.96, which represents an increase of approximately 14.3% to 16.7% over fiscal 2011 diluted earnings per share of $1.68 excluding expenses in that period associated with its divestiture of conventional non-foods and general merchandise lines of business.

In addition, the Company is lowering its guidance on fiscal 2012 capital expenditures to a range of $35 to $40 million.  The Company had previously provided capital expenditure guidance of $47 to $52 million on September 8, 2011.

The following table details the amounts and effect of the expected restructuring and onboarding expenses and the reconciliation of net income and diluted earnings per share guidance, excluding the expected restructuring and onboarding expenses (non-GAAP basis), to net income guidance, including the expected restructuring and onboarding expenses (GAAP basis) for the fiscal year ending July 28, 2012.  All per diluted share amounts in the following table reflect an estimated number of approximately 49.2 million weighted average diluted shares outstanding.

“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 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. Any projections of future results of operations are based on a number of assumptions, many of which are outside the Company’s control and should not be construed in any manner as a guarantee that such results will in fact occur. These projections are subject to change and could differ materially from final reported results. The Company may from time to time update these publicly announced projections, but it is not obligated to do so.

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 the Company’s newest 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 nine months ended April 28, 2012 and expected full year fiscal 2012 excluding these 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 to internally prepared projections.
