EPS Rose to a Third Quarter Record $0.33 per Share Diluted

Quarterly Comparison Overview:

Elgin, IL, April 30, 2014 — John B. Sanfilippo & Son, Inc. (NASDAQ: JBSS) (hereinafter the “Company”) today announced operating results for its fiscal 2014 third quarter. Net income for the third quarter of fiscal 2014 was $3.7 million, or $0.33 per share diluted, compared to net income of $0.3 million, or $0.03 per share diluted, for the third quarter of fiscal 2013. Net income for the first three quarters of fiscal 2014 was $19.7 million, or $1.77 per share diluted, compared to net income of $16.2 million, or $1.47 per share diluted, for the first three quarters of fiscal 2013. Net income for the current third quarter and year to date period included a reduction in income tax expense of $0.6 million, or $0.06 per share diluted. The reduction in income tax expense for both periods was attributable to the tax benefit that resulted from an income tax loss from the divestiture of the Company’s investment in ARMA Energy, Inc. (“AEI”). Even before considering the reduction in income tax expense from the AEI divestiture, both net income and earnings per share diluted were the highest amounts ever reported by the Company for a fiscal quarter ending in March.

Net sales increased to $174.3 million for the third quarter of fiscal 2014 from $163.8 million for the third quarter of fiscal 2013. The increase in net sales was primarily attributable to an 8.1% increase in the weighted average sales price per pound, which was driven mainly by higher selling prices for almonds, mixed nuts (which contain almonds) and walnuts. Sales volume, which is defined as pounds sold to customers, declined by 1.6% in the quarterly comparison. The decline in sales volume was attributable to lower sales of inshell walnuts in the export distribution channel due to

decreased amounts of inshell walnuts available for export and lower sales of raw bulk peanuts to other peanut processors in the commercial ingredients channel due to a smaller peanut crop. The declines in sales volume in these two channels were largely offset by a 4.2% increase in sales volume in the consumer distribution channel. The increase in volume in the consumer distribution channel was driven by increased sales of private brand snack nuts and a 50.2% sales volume increase for Fisher recipe nuts. The substantial increase in sales volume for Fisher recipe nuts was due to increased in-store merchandising activity and product line expansion to larger package sizes by total weight.

Net sales increased to $576.1 million for the first three quarters of fiscal 2014 from $556.9 million for the first three quarters of fiscal 2013. The increase in net sales was primarily attributable to an 8.0% increase in sales volume. Sales volume increased significantly in the consumer, commercial ingredients and contract packaging channels in the year to date comparison. The volume increase in the consumer channel was driven by increased sales of Fisher recipe nuts and increased sales of private brand snack nuts and trail mixes. The sales volume increase in the commercial ingredients channel mainly came from increased sales of almonds to a major customer and increased sales of pecans due to product line expansion at an existing customer. The contract packaging sales volume increase primarily resulted from increased sales of almonds, trail mixes and chocolate- and yogurt-coated products due to new product launches executed by key customers in this channel.

Gross profit margin declined to 13.1% of net sales for the third quarter of fiscal 2014 from 14.0% for the third quarter of fiscal 2013 while gross profit remained relatively unchanged. The gross profit margin decline occurred because selling price increases for almonds, mixed nuts and walnuts were not fully implemented until the end of January while higher commodity acquisition costs for these products affected the entire month of January.

Gross profit margin for the first three quarters of fiscal 2014 decreased to 15.5% of net sales from 16.2% for the first three quarters of fiscal 2013 while gross profit decreased by $1.0 million. The decrease in gross profit margin was primarily due to competitive pricing pressures that existed in the first two quarters of fiscal 2014 and the delay in implementing selling price increases that was discussed in the quarterly comparison. The decline in gross profit margin was offset in part by manufacturing efficiency improvements that were achieved during the current fiscal year to date.

Total operating expenses for the current quarter decreased to 9.6% of net sales from 11.9% of net sales for the third quarter of fiscal 2013. The decrease in total operating expenses, as a percentage of net sales, in the quarterly comparison was mainly due to reductions in incentive compensation expense and advertising expense. Advertising expense declined in the quarterly comparison primarily due to the later Easter holiday, which falls into our 2014 fiscal fourth quarter this year.

Total operating expenses for the first three quarters of fiscal 2014 decreased to 9.4% of net sales from 10.5% of net sales for the year to date period in fiscal 2013. The decrease in total operating expenses, as a percentage of net sales in the year to date comparison was primarily attributable to decreased incentive compensation expense and advertising expense and a gain on the sale of an Elgin, Illinois site that occurred in the second quarter of fiscal 2014. The Elgin, Illinois site was originally purchased in 2006 for the Company’s facility consolidation project. These drivers in the reduction of total operating expenses were offset in part by increased shipping costs.

Interest expense for the third quarter of fiscal 2014 decreased to $1.1 million from $1.2 million for the third quarter of fiscal 2013. Interest expense for the current year to date period was $3.2 million compared to $3.5 million for the first three quarters of fiscal 2013. The decrease in interest expense in the quarterly and year to date comparisons primarily resulted from lower average total borrowing levels.

The value of total inventories on hand at the end of the current third quarter increased by $31.3 million or 18.8% when compared to the value of total inventories on hand at the end of the third quarter of fiscal 2013 primarily due to higher commodity acquisition costs for walnuts, almonds and pecans. As a result of higher acquisition costs for these nuts, the weighted average cost per pound of raw nut input stocks on hand at the end of the current third quarter increased by 23.3% compared to the weighted average cost per pound of raw nut input stocks on hand at the end of last year’s third quarter.

“We are especially pleased with the performance of our Fisher recipe brand during the current quarter as pounds sold increased by 50% over pounds sold in the third quarter of fiscal 2013, and pound and dollar market share also increased significantly in the quarterly comparison,” stated Jeffrey T. Sanfilippo, Chief Executive Officer. “I want to thank our Fisher sales and marketing team for this remarkable accomplishment, especially when considering the later Easter holiday this year,” Mr. Sanfilippo noted. “Our strategy of leveraging our innovation and manufacturing capabilities to grow our business with key non-branded customers also allowed us to realize significant volume gains with many of our major private brand, contract manufacturing and commercial ingredient customers,” Mr. Sanfilippo concluded.
