Net Sales Increased by 16% on Higher Pricing and Strong Sales Volume

Quarterly Comparison Overview:

Elgin, IL, October 23, 2014 — John B. Sanfilippo & Son, Inc. (NASDAQ: JBSS) (the “Company”) today announced operating results for its first quarter of fiscal 2015. Net income for the first quarter of fiscal 2015 was $5.9 million, or $0.53 per share diluted, compared to $6.8 million, or $0.61 per share diluted, for the first quarter of fiscal 2014.

Net sales increased to $205.0 million in the first quarter of fiscal 2015 from net sales of $176.7 million for the first quarter of fiscal 2014 primarily as a result of higher selling prices for most major nut types due to higher commodity acquisition costs. A 7.1% increase in sales volume, which is defined as pounds sold to customers, also contributed to the increase in net sales in the quarterly comparison. Sales volume increased in the consumer and export distribution channels, and sales volume increased for all major product types except pecans. The sales volume increase in the consumer distribution channel came mainly from significant increases in sales of private brand snack nut and trail mix products and Fisher recipe and snack nut products. The sales volume increase in the export distribution channel was due primarily to increased sales of private brand and Fisher snack nuts. Sales volume declined in the contract packaging distribution channel, which was mostly attributable to a former customer discontinuing a seasonal item. The decline in sales volume in the commercial ingredients distribution channel was attributable to lower pecan sales, which primarily resulted from a major customer discontinuing a promotional item that contained pecans.

Gross profit increased by $1.3 million, and gross profit margin, as a percentage of net sales, decreased to 15.0% for the first quarter of fiscal 2015 compared to 16.6% for the first quarter of fiscal 2014. The increase in the gross profit was mainly attributable to increased sales volume. The decrease in gross profit margin was attributable to higher acquisition costs for certain grades of pecans and almonds.

Total operating expenses for the first quarter of fiscal 2015 increased to $18.7 million from $17.0 million for the first quarter of fiscal 2014. The increase in total operating expenses in the quarterly comparison was primarily attributable to increases in shipping expense due to increased sales volume and compensation expense.

Interest expense declined by $0.1 million in the quarterly comparison mainly due to a reduction in short-term and long-term debt. The $1.4 million increase in net rental and miscellaneous expense was attributable to expenses associated with repairs to the exterior of the office building located on our Elgin, Illinois campus. The increase in repair expenses for this project accounted for the majority of the decline in net income in the quarterly comparison. We expect to incur additional expense of approximately $0.4 million to complete the project, which should occur in the second quarter of fiscal 2015.

The value of total inventories on hand at the end of the first quarter of fiscal 2015 increased by $13.4 million, or 8.5%, when compared to the value of total inventories on hand at the end of the first quarter of fiscal 2014. The increase in total inventory value was attributable primarily to increased commodity acquisition costs for all major nut types except cashews. The weighted average cost per pound of raw nut input stocks on hand at the end of the first quarter of fiscal 2015 increased by 7.7% over the weighted average cost at the end of the first quarter of fiscal 2014.

“We continue to see strong sales volume growth, especially in our consumer distribution channel, which increased by almost 19% in the quarterly comparison,” stated Jeffrey T. Sanfilippo, Chairman and Chief Executive Officer. “The increase in volume in the consumer distribution channel came mainly from a 19% volume increase in private brand products driven primarily by increased sales of snack nuts and trail mixes. A 17% increase in volume for Fisher recipe nuts and a 30% increase in volume for Fisher snack nuts also contributed significantly to overall sales volume growth in the consumer distribution channel,” Mr. Sanfilippo noted. “Though the increase in sales volume drove the increase in gross profit, the volume increase in the current first quarter and in the previous three quarters did put pressure on our gross profit margin for the first quarter of 2015. The increased volume depleted our favorable purchase coverage on certain grades of pecans and almonds sooner than anticipated, which ultimately led to increased acquisition costs for these particular nuts when we covered the shortfall during the current first quarter. Consequently, the favorable impact on gross profit from the volume increase did not fully cover the increase in total operating expenses, which partially contributed to the decline in net income in the quarterly comparison,” Mr. Sanfilippo explained. “The majority of the decline in net income in the quarterly comparison was primarily attributable to expenses associated with our Elgin office building repair project, which is expected to be completed in the second quarter,” Mr. Sanfilippo concluded.
