Note: All results and expectations in the presentation reflect continuing operations unless otherwise noted. This presentation contains certain statements relating to future results, which are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995, which reflect management’s expectations about future conditions, including, but not limited to, continued demand in the commercial and government aviation markets, anticipated activities and benefits under extended, expanded and new services, supply and distribution agreements, contributions from our acquisitions, leveraging strengths across our businesses, digital and intellectual property enabled offerings, progress on hangar expansions, continued sales growth, margin expansion, debt management, capital allocation, expenses, production and cost efficiencies, and strategic acquisition opportunities. Forward-looking statements often address our expected future operating and financial performance and financial condition, or targets, goals, commitments, and other business plans, and often may also be identified because they contain words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “likely,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” “target,” “will,” “would,” or similar expressions and the negatives of those terms. These forward-looking statements are based on the beliefs of Company management, as well as assumptions and estimates based on information available to the Company as of the dates such assumptions and estimates are made, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated, depending on a variety of factors, including: (i) factors that adversely affect the commercial aviation industry; (ii) adverse events and negative publicity in the aviation industry; (iii) a reduction in sales to the U.S. government and its contractors; (iv) cost overruns and losses on fixed-price contracts; (v) nonperformance by subcontractors or suppliers; (vi) a reduction in outsourcing of maintenance activity by airlines; (vii) a shortage of skilled personnel or work stoppages; (viii) competition from other companies; (ix) financial, operational and legal risks arising as a result of operating internationally; (x) inability to integrate acquisitions effectively and execute operational and financial plans related to the acquisitions, such as the acquisition of Trax USA Corp. and the Product Support Business of Triumph Group, Inc.; (xi) failure to realize the anticipated benefits of acquisitions; (xii) circumstances associated with divestitures; (xiii) inability to recover costs due to fluctuations in market values for aviation products and equipment; (xiv) cyber or other security threats or disruptions; (xv) a need to make significant capital expenditures to keep pace with technological developments in our industry; (xvi) restrictions on use of intellectual property and tooling important to our business; (xvii) inability to fully execute our stock repurchase program and return capital to stockholders; (xviii) limitations on our ability to access the debt and equity capital markets or to draw down funds under loan agreements; (xix) non-compliance with restrictive and financial covenants contained in our debt and loan agreements; (xx) changes in or non-compliance with laws and regulations related to federal contractors, the aviation industry, international operations, safety, and environmental matters, and the costs of complying with such laws and regulations; and (xxi) exposure to product liability and property claims that may be in excess of our liability insurance coverage. Should one or more of those risks or uncertainties materialize adversely, or should underlying assumptions or estimates prove incorrect, actual results may vary materially from those described. Those events and uncertainties are difficult or impossible to predict accurately and many are beyond our control. For a discussion of these and other risks and uncertainties, refer to our Annual Report on Form 10-K, Part I, “Item 1A, Risk Factors” and our other filings filed from time to time with the U.S. Securities and Exchange Commission. We assume no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

Please refer to the Appendix for additional information on these non-GAAP financial measures and reconciliations to the comparable GAAP measures.

All rights reserved worldwide. 11 Non - GAAP financial measures Adjusted sales, adjusted operating income, adjusted operating margin, adjusted diluted earnings per share, adjusted EBITDA, adjusted EBITDA margin, adjusted pro forma EBITDA, net debt, net debt to adjusted EBITDA, and pro forma net debt to adjusted EBITDA are “non - GAAP financial measures” as defined in Regulation G of the Securities Exchange Act of 1934 , as amended (the “Exchange Act”) . We believe these non - GAAP financial measures are relevant and useful for investors as they illustrate our core operating performance unaffected by the impact of certain items that management does not believe are indicative of our ongoing and core operating activities . When reviewed in conjunction with our GAAP results and the accompanying reconciliations, we believe these non - GAAP financial measures provide additional information that is useful to gain an understanding of the factors and trends affecting our business and provide a means by which to compare our operating performance and leverage against that of other companies in the industries we compete . These non - GAAP measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP . Adjusted EBITDA is income from continuing operations before interest income (expense), other income (expense), income taxes, depreciation and amortization, stock - based compensation, and items of an unusual nature including but not limited to business divestitures and acquisitions, workforce actions, COVID - related subsidies and costs, impairment and exit charges, facility consolidation and repositioning costs, FCPA investigation, settlement, and remediation compliance costs, pension settlement charges, certain legal judgments, acquisition, integration and amortization expenses from recent acquisition activity, and significant customer events such as early terminations, contract restructurings, forward loss provisions, and bankruptcies . Adjusted operating income is adjusted EBITDA gross of depreciation and amortization and stock - based compensation . Pursuant to the requirements of Regulation G of the Exchange Act, we are providing the following tables that reconcile the above - mentioned non - GAAP financial measures to the most directly comparable GAAP financial measures :
