First Quarter EPS Increased by 34% to a First Quarter Record $0.71 per Share Diluted

Quarterly Comparison Overview:

– Net sales increased by 10.1%

– Sales volume was relatively unchanged

– Gross profit increased by 8.2%

– Net income increased by 35.1%

Elgin, IL, October 26, 2015 — John B. Sanfilippo & Son, Inc. (NASDAQ: JBSS) (the “Company”) today announced operating results for its first quarter of fiscal 2016. Net income for the first quarter of fiscal 2016 was $8.0 million, or $0.71 per share diluted, compared to $5.9 million, or $0.53 per share diluted, for the first quarter of fiscal 2015.

Net sales increased by 10.1% to $225.8 million in the first quarter of fiscal 2016 from net sales of $205.0 million for the first quarter of fiscal 2015 as a result of higher selling prices for most major nut types due to higher commodity acquisition costs. Sales volume, which is defined as pounds sold to customers, was relatively unchanged in the quarterly comparison. Sales volume declined in the consumer distribution channel mainly due to a 28.7% decline in volume for almond products. The decline in almond sales volume occurred primarily with existing private brand customers and was a contributing factor to a 1.4% decline in Fisher recipe nut sales volume. The decline in almond sales volume was attributable to the overall negative impact on consumer demand from significantly higher retail prices. Sales volume for Fisher snack nuts was down by 2.4%, which was mainly driven by lower peanut sales to an existing customer due to the timing of promotional activity. These sales volume declines were partially offset by new sales of Fisher Nut Exactly snack bites. Combined sales volume for Orchard Valley Harvest and Sunshine Country produce products increased by 2.8% in the quarterly comparison. The sales volume decline in the consumer distribution channel was offset by a sales volume increase in the contract packaging distribution channel, which primarily came from new product launches made by existing customers in that channel. Sales volume was relatively unchanged in the commercial ingredients and export distribution channels.

Gross profit increased by 8.2% to $33.2 million for the first quarter of fiscal 2016 compared to $30.7 million for the first quarter of fiscal 2015. The increase in gross profit was mainly attributable to improved alignment of selling prices and commodity acquisition costs. Gross profit margin, as a percentage of net sales, declined to 14.7% for the first quarter of fiscal 2016 compared to 15.0% for the first quarter of fiscal 2015. The gross profit margin decline was primarily driven by an increase in the manufacturing cost per produced pound, which was due to higher manufacturing spending and reduced shelling production for pecans, walnuts and peanuts in the quarterly comparison. Higher manufacturing spending mainly came from increases in employee related expenses, operating supplies and repair and maintenance expense. The shelling production decline occurred because the shelling of the pecan, walnut and peanut crops were completed earlier in the current first quarter in comparison to the completion of shelling in last year’s first quarter.

Total operating expenses, as a percentage of net sales, declined to 8.6% from 9.1% for the first quarter of fiscal 2016 due to increased net sales. Total operating expenses increased to $19.5 million from $18.7 million in the quarterly comparison. The increase in total operating expenses was primarily attributable to increases in product sampling, advertising and employee related expenses, which were offset in part by a decrease in shipping expense.

Interest expense declined by $0.1 million in the quarterly comparison mainly due to a reduction in long-term debt. Net rental and miscellaneous expense declined by $1.4 million in the quarterly comparison because last year’s first quarter included expenses associated with the repairs to the exterior of the office building located on our Elgin, Illinois campus. This project was completed during the second quarter of fiscal 2015.

The value of total inventories on hand at the end of the first quarter of fiscal 2016 increased by $16.5 million, or 9.6%, when compared to the value of total inventories on hand at the end of the first quarter of fiscal 2015. The increase in total inventory value was attributable primarily to increased acquisition costs for almonds and cashews and higher quantities of peanut, walnut, and work-in-process inventories on hand, which were offset in part by a decrease in the quantity of finished goods inventory on hand. The weighted average cost per pound of raw nut and dried fruit input stocks on hand at the end of the first quarter of fiscal 2016 was relatively unchanged compared to the weighted average cost per pound at the end of the first quarter of fiscal 2015.

“In respect to net income and diluted earnings per share, operating results for the current first quarter mark the third consecutive quarter where we have reported record earnings,” stated Jeffrey T. Sanfilippo, Chief Executive Officer. “Despite significant sales volume challenges for almonds due to high retail prices, we were able to maintain overall sales volume in the quarterly comparison primarily as a result of strong volume performance in our contract packaging distribution channel. To a large extent, the sales volume increase in the contract packaging channel resulted from leveraging our production and innovation capabilities to assist our key contract packaging customers in launching new items, a key component of our Strategic Plan,” stated Mr. Sanfilippo. “Sales volume gains for Fisher Nut Exactly snack bites and Orchard Valley Harvest and Sunshine Country produce products also made meaningful contributions in offsetting the decline in sales volume for almonds,” Mr. Sanfilippo added. “We acquired the

2

assets of Orchard Valley Harvest (“OVH”) in fiscal 2010, and relaunched the brand in fiscal 2012 to be more on trend and better meet the needs of consumers. We reformulated the products for a cleaner ingredient line, updated product packaging and introduced convenient snack consumption options, such as “on-the-go” minis and multipacks. We replaced the original OVH line with the current OVH product line in all but one major retailer. We are now launching the OVH on-the-go packs and transitioning the remainder of the line to our Sunshine Country brand at that major retailer. As a result of this brand replacement, pound volume for OVH produce products declined by 13.7% at retail according to IRI data for the quarterly comparison, which was largely offset by Sunshine Country increases,” Mr. Sanfilippo noted. “Though our sales volume declined for Fisher recipe nuts, Fisher recipe nuts outperformed the recipe nut category at retail with flat pound volume, while pound volume in that category fell by 8.7% according to IRI data for the quarterly comparison. Fisher snack nut pound volume at retail declined by 4.2% compared to a pound volume increase of 0.6% for the entire snack nut category according to IRI data for the quarterly comparison. The Fisher snack nut underperformance in that category was attributable to reduced merchandising activity,” Mr. Sanfilippo stated. “We continue to be excited about our new distribution gains for our Fisher Nut Exactly snack bite products and Orchard Valley Harvest produce products as part of our overall strategy in building our brands,” Mr. Sanfilippo stated. “As we noted above, retail consumers appear to be reacting negatively to high almond prices. For example, according to IRI data for the quarterly comparison, retail price increases for almonds ranged between 15% and 20%, while almond pound volume declined by approximately 11%, 22% and 13% in the snack nut, recipe nut and produce categories, respectively. We anticipate that sales volume declines for almonds will continue for the remainder of fiscal 2016 due to such historically high almond prices. To counter this trend, we will continue to focus on growing our brands and increasing our sales volume with existing key customers,” Mr. Sanfilippo concluded.
