APPENDIX NASDAQ: NOVT

Use of Non-GAAP The non-GAAP financial measures used in this presentation are non-GAAP Adjusted Revenue, Adjusted EBITDA, and Adjusted Diluted EPS from continuing operations. The Company believes that these non-GAAP financial measures provide useful and supplementary information to investors regarding the Company’s operating performance. It is management’s belief that these non-GAAP financial measures would be particularly useful to investors because of the significant changes that have occurred outside of the Company’s day-to-day business in accordance with the execution of the Company’s strategy. This strategy includes streamlining the Company’s existing operations through site and functional consolidations, strategic divestitures and product line closures, expanding the Company’s business through significant internal investments, and broadening the Company’s product and service offerings through acquisition of innovative and complementary technologies and solutions. The financial impact of certain elements of these activities, particularly acquisitions, divestitures, and site and functional restructurings, is often large relative to the Company’s overall financial performance, which can adversely affect the comparability of its operating results and investors’ ability to analyze the business from period to period. Adjusted Revenue excludes the JK Lasers business to only show the results of ongoing operations of the Company as the JK Lasers business was sold in April 2015. We excluded JK Lasers sales from Adjusted Revenue because divestiture activities can vary between reporting periods and between us and our peers, which we believe make comparisons of long-term performance trends difficult for management and investors, and could result in overstating or understating to our investors the performance of our operations. Additionally, we include estimated revenue from contracts acquired with business acquisitions that will not be fully recognized due to business combination rules. Because GAAP accounting rules require the elimination of this revenue, GAAP results alone do not fully capture all of our economic activities. These non-GAAP adjustments are intended to reflect the full amount of such revenue. The Company defines Adjusted EBITDA as Operating Income (loss) from Continuing Operations before deducting depreciation, amortization, non-cash share-based compensation, restructuring, acquisition, divestiture and other costs, impairment of goodwill and intangible assets, acquisition fair value adjustments, CEO transition costs and inventory related charges associated with product line closures. The Company’s Adjusted EBITDA is used by management to evaluate operating performance internally, communicate financial results to the Board of Directors, benchmark results against historical performance and the performance of peers, and evaluate investment opportunities including acquisitions and divestitures. In addition, Adjusted EBITDA is used to determine bonus payments for senior management and employees. Accordingly, the Company believes that this non-GAAP measure provides greater transparency and insight into management’s method of analysis. Adjusted Diluted EPS from Continuing Operations excludes amortization of acquired intangible assets and revenue fair value adjustments related to business acquisitions, restructuring, acquisition, divestiture, and other costs, inventory related charges associated with product line closures, CEO transition costs, the gain on sale of JK Lasers and the related unrealized foreign exchange loss on the U.S. dollar sales proceeds held by our U.K. subsidiary, impairment of goodwill and intangible assets, gain on acquisition of business, significant non-recurring income tax expenses (benefits) related to releases of valuation allowance, effects of changes in tax laws, income tax audit settlements, effects of acquisition related tax planning actions on our effective tax rate, and the income tax effect of non-GAAP adjustments. In addition, the Company excluded the adjustment of redeemable noncontrolling interest to estimated redemption value as (1) the adjustment is unusual; (2) the amount is noncash; (3) the amount is excluded from the determination of net income attributable to Novanta Inc.; and (4) the Company believes that it may not be indicative of future adjustments and that investors may benefit from an understanding of the Company's results without giving effect to this adjustment. The Company also uses Adjusted Diluted EPS as a measurement for performance shares issued to certain executives. Non-GAAP financial measures should not be considered as substitutes for, or superior to, measures of financial performance prepared in accordance with GAAP. They are limited in value because they exclude charges that have a material effect on the Company’s reported results and, therefore, should not be relied upon as the sole financial measures to evaluate the Company’s financial results. The non-GAAP financial measures are meant to supplement, and to be viewed in conjunction with, GAAP financial measures. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this document.
