Certain statements contained in this Current Report on Form 8-K may be deemed to be forward-looking statements under federal securities laws, and we intend that such forward-looking statements be subject to the safe-harbor created thereby. Such forward-looking statements include, but are not limited to, statements regarding our belief there is an ongoing consumer preference for our concealed carry firearms; our belief that the M&P 15 Sport provides a great value for consumers and is the industry-leading rifle in this category; our belief that our products remain popular with consumers and that we remained the market leader in the handgun and the modern sporting rifle categories during the fourth quarter; our belief that inventories need to increase in preparation for the busy season of consumer activity that typically commences in September; our expectation that we will work closely with our wholesaler partners to ensure their inventory levels are appropriate for the current period; our belief that our new accessories division provides us with a broad, established platform for organic and inorganic growth in hunting and firearm accessories; our belief regarding the return to a more normalized consumer firearm market following an

earlier surge in demand; our goal to maintain EBITDAS margins above 20%; the success of our efforts to reduce our ongoing interest expense; potential uses of revolving line of credit; expectations regarding our 5.000% Senior Notes; our belief that consumer demand continues to trend to its normal, seasonal pattern; our expectations regarding trends based on NICS checks; the success of our strategy, including related to new products; our expectations about the new products that we have in the pipeline for the next three years, including our next generation M&P polymer pistol; our expectations regarding capital expenditures for fiscal 2016; our expectations regarding the Army’s solicitation for a modular handgun system; the opportunities the acquisition of Battenfeld Technologies, Inc. provides to recognize revenue synergies with our firearms division; our expectations regarding our accessories division, including that it will deliver double-digit, annual revenue growth, that revenue for that division is poised to grow in fiscal 2016, and it has the potential to deliver strong top line growth, both organic and inorganic, as well as very attractive gross margins; our expectations regarding our operational capacity and retail traffic during fiscal 2016; our expectations regarding our seasonable patterns in fiscal 2016, including its impact on our revenue by quarter; our estimates for revenue, GAAP and non-GAAP earnings per share, including adjustments, fully diluted share count, and tax rate for our first quarter and for full fiscal 2016; our belief that our industry is in the midst of a long-term, underlying growth trend; our expectations regarding growing our company and its share of our market; our expectations regarding our gross margins; our belief that the consumer firearm market is a heavy promotional environment with a lot of incentives; our goal of creating business by taking market share; our plans to remain aggressive with respect to promotional activities and wholesaler shows; our expectation that we will incur employee incentive expenses in fiscal 2016; our belief that employee incentive expenses will probably be the biggest driver of increased operating expenses in fiscal 2016 other than expenses associated with Battenfeld; our belief that we are strongly positioned to take market share and grow with an expanding market; our belief that the new products that we have in the pipeline will help us take more market share and strengthen our position; our goal to create flexibility on our balance sheet in order to act quickly if an acquisition opportunity arises, invest in our business or execute a share buyback if appropriate; our goal to lower our overall weighted average cost of capital; our belief that our understanding of forecasting metrics is better than ever before and helps us schedule the plant, collaborate with our strategic partners, wholesalers, and big box stores, time the launch of new products, and undertake strategic promotional activities; our expectation that Battenfeld will continue to grow very strongly; our estimates regarding the long-term prospects of the firearm industry; our belief that we will maintain or increase our market share; our belief regarding the return to a more normalized firearm market despite our competitors’ inventory levels; our belief that we are a brand of choice when it comes to the consumer; our belief that we have one of the strongest product portfolios in the firearm market; our expectation that capital expenditures in excess of our normal range will be due to a specialized IT project, capacity increases, or new product launches; our preference to execute a share buyback if we have excess cash; our belief that our leverage is very low; our expectation that we will not draw on our revolving line of credit immediately; our belief that our accessories business maintains a flatter demand profile and does not follow the seasonal pattern seen in the firearm industry more generally; our evaluation of acquisition opportunities with respect to our firearm and accessories divisions as well as opportunities for vertical integration; and our plan to integrate our Thompson/Center Arms accessories business and M&P accessories business into our accessories division.
