WSI INDUSTRIES REPORTS FISCAL 2016 First QUARTER Financial RESULTS

December 21, 2015—Minneapolis, MN – WSI Industries, Inc. (NASDAQ: WSCI) today reported sales for its fiscal 2016 first quarter ending November 29, 2015 of $9,731,000, versus the prior year amount of $10,098,000. Net income for the fiscal 2016 first quarter was $132,000 or $.05 per diluted share versus the prior year quarter of $167,000 or $.06 per diluted share.

Related to the quarter results, Benjamin Rashleger, president and chief executive officer, commented: “Our fiscal 2016 first quarter sales were down from the prior year quarter due to the continued slump in our energy business. However, our core business in the recreational powersports market experienced another rise with sales increasing by 11% over the prior year quarter.” Rashleger continued: “The impact of the low price of oil and natural gas has essentially idled our energy related business. This reduction has, and will continue to, impact our results while we backfill our available and underutilized capacity which leaves us well positioned to capture new business.”

Related to the business, Rashleger commented: “We understand the importance of having a robust business development system in place to drive our diversification and growth goals. We have been making important and strategic changes to our organization and strategy as it relates to business development, and we were pleased to recently announce the addition of Tom Schmeling as our Director of Business Development and Marketing. Tom will lead an independent and dedicated department and team with the sole responsibility of developing new business in strategic industries and with strategic accounts in those industries. Tom will be responsible for all of our business development and marketing strategies and the execution towards those strategies. We are excited about the potential Tom will bring to our organization, and for the benefit his contribution and leadership will bring to our diversification and growth goals. Tom’s addition will complement and further improve the traction we’ve developed in our current business development efforts, and we believe the quality of our existing opportunities remains good.”

The Company also announced today that its Board of Directors has declared a quarterly dividend of $.04 per share. The dividend will be payable January 20, 2016 to holders of record on January 6, 2016.
