BIG 5 SPORTING GOODS CORPORATION ANNOUNCES FISCAL 2015 THIRD QUARTER RESULTS

EL SEGUNDO, Calif., October 27, 2015 — Big 5 Sporting Goods Corporation (NASDAQ: BGFV) (the “Company”), a leading sporting goods retailer, today reported financial results for the fiscal 2015 third quarter ended September 27, 2015.

For the fiscal 2015 third quarter, net sales increased to $270.1 million from net sales of $265.1 million for the third quarter of fiscal 2014. Same store sales decreased 0.4% for the third quarter of fiscal 2015.

Gross profit for the fiscal 2015 third quarter was $85.2 million, compared to $86.1 million in the third quarter of the prior year. The Company’s gross profit margin was 31.5% in the fiscal 2015 third quarter versus 32.5% in the third quarter of the prior year, reflecting a decrease in merchandise margins of 51 basis points and an increase in store occupancy costs as a percentage of net sales.

Selling and administrative expense as a percentage of net sales was 27.7% in the fiscal 2015 third quarter versus 27.9% in the third quarter of last year. The Company’s selling and administrative costs for the fiscal 2015 third quarter increased $1.1 million from the prior year due primarily to higher employee labor expense and operating expense to support the increase in store count.

Net income for the third quarter of fiscal 2015 was $6.1 million, or $0.28 per diluted share, compared to net income for the third quarter of fiscal 2014 of $7.5 million, or $0.34 per diluted share.

For the 39-week period ended September 27, 2015, net sales increased to $754.1 million from net sales of $727.5 million in the comparable period last year. Same store sales increased 1.7% in the first 39 weeks of fiscal 2015 versus the comparable period last year. Net income was $11.0 million, or $0.50 per diluted share, including $0.06 per diluted share of charges for a legal settlement and expenses associated with the Company’s publicly disclosed proxy contest, for the first 39 weeks of fiscal 2015, compared to net income of $12.1 million, or $0.54 per diluted share, including $0.02 per diluted share of non-cash impairment charges, for the first nine months of fiscal 2014.

“Although we delivered earnings in-line with our guidance, our sales fell slightly short of our expectations,” said Steven G. Miller, the Company’s Chairman, President and Chief Executive Officer. “Our footwear category comped positively for the period, while our apparel and hardgoods categories each comped down low single-digits. As expected, sales were challenged by cycling the benefit of Men’s World Cup soccer-influenced sales during the third quarter of last year, as well as by the continuing impact of the drought in our markets on certain summer-related product categories.”

Mr. Miller continued, “Our same store sales are down low single-digits versus the prior year for the start of the fourth quarter, which historically is a low-volume period for our business. While we feel well positioned from a product and promotional perspective for the balance of the quarter, we do anticipate that the holiday period will be highly promotional again this year and, as always, weather conditions will be critical to the performance of our winter product business. We continue to work vigorously to improve same store sales and traffic trends, drive gross margin improvements and control expenses. To help ensure we are best positioned to succeed in the evolving retail environment, we have engaged consultants to assist us in evaluating store growth strategies and identifying potential avenues of profit enhancement, and we look forward to working on these initiatives.”

Quarterly Cash Dividend

The Company’s Board of Directors has declared a quarterly cash dividend of $0.10 per share, which will be paid on December 15, 2015 to stockholders of record as of December 1, 2015.

Share Repurchases

In the third quarter of fiscal 2015, the Company repurchased 181,969 shares of its common stock for a total expenditure of $2.0 million. For the year-to-date period through September 27, 2015, the Company repurchased 278,242 shares of its common stock for a total expenditure of $3.2 million. As of September 27, 2015, the Company had $3.9 million available for future share repurchases under its $20.0 million share repurchase program.

Guidance

For the fiscal 2015 fourth quarter, the Company expects same store sales to be in the low negative single-digit to low positive single-digit range and earnings per diluted share to be in the range of $0.10 to $0.20, including approximately $0.01 per diluted share of consulting expenses related to evaluating store growth strategies and potential profit improvement opportunities. As a result of the fiscal calendar, the fourth quarter of fiscal 2015 will include 14 weeks and the fourth quarter last year included 13 weeks. The Company’s same store sales guidance above reflects comparable 14-week periods.

Store Openings

During the third quarter of fiscal 2015, the Company opened one new store and closed one store, ending the quarter with 439 stores in operation. For the fiscal 2015 full year, the Company currently anticipates opening five new stores and closing five stores.
