FOR IMMEDIATE RELEASE

Quarterly Overview:

Elgin, IL, October 27, 2011 — John B. Sanfilippo & Son, Inc. (NASDAQ: JBSS) (the “Company”) today announced operating results for its first quarter of fiscal 2012. Net income for the first quarter of fiscal 2012 was $2.4 million, or $0.23 per share diluted, compared to $1.1 million, or $0.10 per share diluted, for the first quarter of fiscal 2011.

Net sales increased by $10.0 million, or 6.8%, to $156.8 million in the first quarter of fiscal 2012 from net sales of $146.8 million for the first quarter of fiscal 2011. The increase in net sales resulted from higher selling prices generated by pricing actions taken since the first quarter of fiscal 2011. Sales prices increased for all major product types due to higher commodity acquisition costs. Sales volume, which is defined as pounds shipped to customers, in the first quarter of fiscal 2012 decreased by 6.8% in comparison to sales volume for the first quarter of fiscal 2011. Sales volume decreased in all distribution channels mainly because of the impact of higher selling prices on consumer demand.

Gross profit increased by $1.2 million, and gross profit margin, as a percentage of net sales, decreased nominally to 13.9% for the first quarter of fiscal 2012 compared to 14.0% for the first quarter of fiscal 2011. The nominal decline in gross profit margin occurred as a result of a decline in gross profit margins on sales of cashews and products containing cashews, such as fruit and nut mixes and mixed nuts, due to a significant increase in cashew acquisition costs since the first quarter of fiscal 2011. The decline in gross profit margins on sales of these cashew products were offset by increases in gross profit margins on sales of walnuts, almonds,

peanuts, pistachios and pine nuts. The increase in gross profit margins on sales of these products primarily led to the $1.2 million increase in gross profit.

Total operating expenses for the first quarter of fiscal 2012 declined by $0.8 million to 10.4% of net sales from 11.6% for the first quarter of fiscal 2011 primarily because of a fair value adjustment recorded within administrative expense in the first quarter of fiscal 2011, which did not recur in the first quarter of fiscal 2012. The fair value adjustment recorded in the first quarter of fiscal 2011 related to the Orchard Valley Harvest earn-out liability.

Interest expense declined by $0.1 million in the quarterly comparison due to lower interest rates on our revolving credit facility and a decline in long term debt.

The total value of inventories on hand at the end of the first quarter of fiscal 2012 decreased by $2.3 million, or 2.0%, in comparison to the total value of inventories on hand at the end of the first quarter of fiscal 2011. Pounds of raw nut input stocks decreased by 22.0%, or 5.8 million pounds, as of the end of the first quarter of fiscal 2012 compared to pounds of raw nut input stocks on hand at the end of the previous year’s first quarter. Due to higher acquisition costs for most tree nuts that were purchased during the first quarter of fiscal 2012, the weighted average cost per pound of raw nut input stocks on hand increased by 18.4% as of the end of the first quarter of fiscal 2012 when compared to the weighted average cost per pound of raw input stocks as of the end of the same period in the prior year.

“Net income for the first quarter of fiscal 2012 more than doubled in comparison to net income for the previous year’s first quarter primarily due to improved alignment of sales prices and acquisition costs for most of the products that we sell, except for cashew products,” stated Jeffrey T. Sanfilippo, Chairman and Chief Executive Officer. “Pricing actions for cashews and products containing cashews are anticipated to be completed in the second quarter of fiscal 2012,” Mr. Sanfilippo added. “We expect that acquisition costs for most tree nuts should be relatively stable for the 2011 crop year (which falls into our 2012 fiscal year), but acquisition costs will remain at levels that are significantly higher than historical averages,” Mr. Sanfilippo noted. “Unlike tree nuts, peanut market prices for the 2011 crop have increased over 100% in comparison to peanut market prices for the 2010 crop. This remarkable increase in peanut market prices is due to reduced acreage, reduced yields caused by drought conditions in the majority of the peanut growing areas and the poor quality of the 2010 crop carryover stocks. Consistent with what has appeared in recent articles regarding the 2011 peanut crop, we also believe that there is a possibility of a peanut shortage during the 2011 crop year,” Mr. Sanfilippo stated. “Under these conditions, being a peanut sheller can deliver meaningful advantages. As a peanut sheller, we leveraged our longstanding relationships with our peanut farmers so that sufficient peanut acreage was planted to meet the majority of our peanut requirements. Additionally, because we entered into purchase contracts with our peanut farmers prior to planting in February and March and fixed our purchase costs at that time, we were therefore able to avoid a considerable portion of the year-over-year peanut market price increase,” Mr. Sanfilippo explained. “Consequently, we should be well positioned to meet our customers’ peanut needs over the next twelve months, assuming that the negative impact of the drought conditions on crop quality and yield does not exceed what we are anticipating,” Mr. Sanfilippo concluded.
