First Quarter 2014 Net Income was $6.8 Million

Quarterly Overview:

Elgin, IL, October 28, 2013 — John B. Sanfilippo & Son, Inc. (NASDAQ: JBSS) (the “Company”) today announced operating results for its first quarter of fiscal 2014. Net income for the first quarter of fiscal 2014 was $6.8 million, or $0.61 per share diluted, compared to $7.5 million, or $0.69 per share diluted, for the first quarter of fiscal 2013. Approximately 50% of the $0.8 million decline in net income was attributable to the first quarter of fiscal 2013 containing a pre-tax gain on sale of assets of $0.6 million.

Net sales decreased slightly to $176.7 million in the first quarter of fiscal 2014 from net sales of $177.5 million for the first quarter of fiscal 2013 while sales volume, which is defined as pounds sold to customers, increased by 14.0%. The favorable impact on net sales from the sales volume increase was offset by lower selling prices. Selling prices decreased mainly in pecan and peanut products in response to lower acquisition costs. Competitive pricing pressure at two of our major private brand customers also contributed to the overall decrease in selling prices. Sales volume increased in the contract packaging, commercial ingredients and consumer distribution channels, and sales volume increased for all major product types except cashews and walnuts, both of which were relatively unchanged. The sales volume increase in the contract packaging distribution channel came primarily from new product launches and increased promotional activity implemented by a major existing customer. The sales volume increase in the commercial ingredients distribution channel was due primarily to increases in sales of (i) lower-priced products such as peanut crushing stock due to a record peanut harvest, (ii) almond products as a result of distribution gains achieved by a major existing customer and (iii) pecan

products due to the favorable impact on customer demand from lower selling prices. The sales volume increase in the consumer distribution channel primarily came from increased sales of private brand trail mix, snack nut and peanut butter products. Increased sales of Orchard Valley Harvest produce products also contributed to the sales volume increase. The increase in sales volume for these products was partially offset by a sales volume decrease in Fisher inshell peanut products due to reduced distribution at a major Fisher snack nut customer as a result of competitive pricing pressure. Fisher recipe nut sales volume declined marginally mainly due to reduced merchandising activity at a major Fisher recipe nut customer.

Gross profit decreased by $1.2 million, and gross profit margin, as a percentage of net sales, decreased to 16.6% for the first quarter of fiscal 2014 compared to 17.2% for the first quarter of fiscal 2013. The decreases in the gross profit and gross profit margin occurred primarily because of reduced selling prices to two of our major private brand customers caused by competitive pricing pressure. The decreases in gross profit and gross profit margin were offset in part by manufacturing efficiency improvements achieved during the quarter and the increase in sales volume. The increase in sales volume did not fully offset the reduction in gross profit and gross profit margin because the sales volume increase was generated mainly by increases in sales of lower-priced products.

Total operating expenses for the first quarter of fiscal 2014 increased to $17.0 million from $16.7 million for the first quarter of fiscal 2013. The increase in total operating expenses in the quarterly comparison occurred because total operating expenses in the first quarter of fiscal 2013 included a $0.6 million gain on the sale of assets.

Interest expense declined by $0.2 million in the quarterly comparison mainly due to a reduction in short-term and long-term debt.

The value of total inventories on hand at the end of the first quarter of fiscal 2014 increased by $23.4 million, or 17.4%, when compared to the value of total inventories on hand at the end of the first quarter of fiscal 2013. The increase in total inventory value was attributable primarily to increased quantities of raw nut input stocks and finished goods to support increasing sales volume. The weighted average cost per pound of raw nut input stocks on hand at the end of the first quarter of fiscal 2014 decreased by 15% over the weighted average cost at the end of the first quarter of fiscal 2013. The decrease in the weighted average cost per pound in the quarterly comparison was mainly attributable to lower acquisition costs for peanuts and pecans which were offset in part by higher acquisition costs for almonds.

“As you may recall, we reported record first quarter net sales and net income last fiscal year,” stated Jeffrey T. Sanfilippo, Chairman and Chief Executive Officer. “Notwithstanding the challenges we faced in the current first quarter, such as competitive pricing pressure with some of our major customers, we nearly matched those record levels, especially after factoring out the unfavorable impact on net income from sales of assets in the quarterly comparison. Significantly lower peanut selling prices compared to peanut selling prices in last year’s first quarter also put additional pressure on net sales and gross profit in the current first quarter,” Mr. Sanfilippo noted. “We recognized these challenges early on and responded to them by achieving meaningful efficiency improvements in our operations in continuance of our lean manufacturing efforts and by gaining new sales volume in our contract packaging and commercial ingredients distribution channels with existing key customers. As mentioned above, we were not provided with the opportunity to merchandise Fisher recipe nuts at a major Fisher recipe nut customer in

the current first quarter that was provided by that customer in last year’s first quarter. We also saw a sales volume decline for Fisher recipe nuts at certain government customers due to the sequester. Despite these challenges at these Fisher recipe nut customers, Fisher recipe nut share grew in both dollar and pound terms in the quarterly comparison according to Nielsen data,” Mr. Sanfilippo stated. “I am especially proud of the efforts of our employees in meeting these challenges and delivering a strong first quarter,” Mr. Sanfilippo concluded.
