Updates Financial Expectations

Increasing Guidance for Fourth Quarter and Full 2015 Fiscal Year Net Sales and Earnings Per Share

SPRINGFIELD, Mass., April 15, 2015 — Smith & Wesson Holding Corporation (NASDAQ Global Select: SWHC), a leader in firearm manufacturing and design, today announced that it is updating expectations for its fourth quarter and full 2015 fiscal year, which will end April 30, 2015. The company indicated that orders throughout its fiscal fourth quarter have been stronger than originally anticipated and it is therefore increasing its guidance.

Financial Outlook

For the fourth quarter of fiscal 2015, the company expects net sales of between $175.0 million and $179.0 million and GAAP earnings per diluted share from continuing operations of between $0.34 and $0.36. On a non-GAAP basis, the company expects earnings per diluted share to be between $0.39 and $0.41. (See below “Reconciliation of Expected GAAP Earnings per Share from Continuing Operations to Expected Non-GAAP Earnings per Share from Continuing Operations” table.)

For full 2015 fiscal year, the company expects net sales of between $546.0 million and $550.0 million and GAAP earnings per diluted share from continuing operations of between $0.84 and $0.86. On a non-GAAP basis, the company expects earnings per diluted share to be between $0.96 and $0.98. (See below “Reconciliation of Expected GAAP Earnings per Share from Continuing Operations to Expected Non-GAAP Earnings per Share from Continuing Operations” table.)

Reconciliation of U.S. GAAP to Non-GAAP Financial Measures

In this press release, certain non-GAAP financial measures, including non-GAAP earnings per share from continuing operations, are presented. From time-to-time, the company considers and uses these supplemental measures of operating performance in order to provide the reader with an improved understanding of underlying performance trends. The company believes it is useful for itself and the reader to review, as applicable, both GAAP measures that include: (i) fair value inventory step-up and backlog expense, (ii) amortization of acquired intangible assets, (iii) acquisition-related costs, and (iv) the tax effect of non-GAAP adjustments, which are primarily related to the acquisition of Battenfeld Technologies, Inc., and the non-GAAP measures that exclude such information. The company presents these non-GAAP measures because it considers them an important supplemental measure of its performance. The company’s definition of these adjusted financial measures may differ from similarly named measures used by others. The company believes these measures facilitate operating performance comparisons from period to period by eliminating potential differences caused by the existence and timing of certain expense items that would not otherwise be apparent on a GAAP basis. These non-GAAP measures have limitations as an analytical tool and should not be considered in isolation or as a substitute for the company’s GAAP measures. The principal limitations of these measures are that they do not reflect the company’s actual expenses and may thus have the effect of inflating its financial measures on a GAAP basis.
