Hedges, Vice President & CFO astronics.com 26 Astronics Corporation SUPPLEMENTAL INFORMATION INNOVATION. COLLABORATION. SUCCESS. 27 By structuring the new convertible notes with Net Share Settlement, Astronics will only incur share dilution for the in-the- money amount upon conversion If the Company did not have a capped call in place, this would also represent the economic dilution Net Share Dilution from the Convertible = 4.1mm x (Stock Price – Conversion Price) / Stock Price (1) Astronics owns capped call options that provide actual share dilution protection benefit from $54.87 to $83.41 Increases the effective conversion price to $83.41 However, under GAAP, capped call benefits are anti-dilutive and cannot be used to reduce the dilutive impact from the convertible until maturity / settlement As a result, GAAP EPS dilution under Treasury Stock Method begins from $54.87 Taking into account (1) Net Share Settlement where Astronics repays the principal amount in cash and only delivers in-the-money amount in shares and (2) capped call benefits, actual share dilution starts only from $83.41. Above this point, dilution is gradual and calculated under Treasury Stock Method Some companies report this dilution in the adjusted EPS as it shows the actual economic reality of the convertible dilution Net share settlement and capped call will have the effect of increasing the “no dilution point” of the convertible to $83.41 (1) Zero if stock price is below conversion price.. As part of this transaction, Astronics removed ~ 5.8mm of shares underlying the existing convertible notes through an all- cash repurchase. Share Dilution Removed = ~$132mm Principal Repurchased / $22.89 existing conversion price As the cash repurchase of the existing notes is equivalent to a leverage-friendly share repurchase, Astronics further mitigates overall dilution Total Potential Share Dilution After Repurchase Net Potential Share Dilution on New 2025 Convertible Bond Shares Receivable from Capped Call Hedge New 2025 Convertible Bond - Potential Dilution on Premium Above Conversion Price Potential Dilution Repurchased From Existing Convertible Potential Dilution from Existing 2024 Convertible Bond Stock Price at Maturity 1.40.00.00.0(5.8)7.2$43.8974 1.40.00.00.0(5.8)7.2$50.00 1.40.0(0.4)0.4(5.8)7.2$60.00 1.40.0(0.9)0.9(5.8)7.2$70.00 1.40.0(1.3)1.3(5.8)7.2$80.00 1.70.3(1.3)1.6(5.8)7.2$90.00 2.10.7(1.2)1.9(5.8)7.2$100.00 2.41.0(1.1)2.1(5.8)7.2$110.00 2.71.3(1.0)2.2(5.8)7.2$120.00 2.91.5(0.9)2.4(5.8)7.2$130.00 3.11.7(0.8)2.5(5.8)7.2$140.00 Dilution Impact from Astronics’ New Convertible and Capped Call Extensive List of Customers Representative List 280+ Airlines Airbus AMAC Aerospace Bell Helicopter Boeing Bombardier Cessna Cirrus Aircraft Collins Aerospace Comlux Dassault Aviation Delta Flight Products Embraer General Dynamics Gulfstream Honda Aircraft Honeywell Hughes Intelsat Jet Aviation Sikorsky Textron Aviation Thales Thompson Aero Seating U.S. Army/Navy/Air Force/Marines Viasat astronics.com 28 Kawasaki L3Harris Leonardo Lockheed Martin NASA Northrup Grumman Panasonic Avionics Pilatus Raytheon Technologies Safran

The Company’s management believes Adjusted EBITDA is an important measure of operating performance because it allows management, investors and others to evaluate and compare the performance of its core operations from period to period by removing the impact of the capital structure (interest), tangible and intangible asset base (depreciation and amortization), taxes, equity- based compensation expense, goodwill, and other items as noted previously which are not commensurate with the core activities of the reporting period in which it is included. As such, the Company uses Adjusted EBITDA as a measure of performance when evaluating its business and as a basis for planning and forecasting. Adjusted EBITDA is not a measure of financial performance under GAAP and is not calculated through the application of GAAP. As such, it should not be considered as a substitute for the GAAP measure of net income and, therefore, should not be used in isolation of, but in conjunction with, the GAAP measure. Adjusted EBITDA, as presented, may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies. 1 The sum of the four discrete quarters for the year ended December 31, 2024, does not sum to the zero-balance shown for the full year. In the first quarter of 2024, it was assumed that annual incentive compensation would be paid in stock, and thus such amount ($1.4 million) was presented as an addback for Adjusted EBITDA purposes. In the fourth quarter of 2024, it was concluded that all annual incentive compensation amounts would be paid in cash, and thus the addback for the full year has been eliminated. A reconciling adjustment has not been made to the quarter ended December 31, 2024, as it is deemed unnecessarily distortive to the Adjusted EBITDA measure for the quarter.

As such, it should not be considered as a substitute for the GAAP measure of net income and, therefore, should not be used in isolation of, but in conjunction with, the GAAP measure. Adjusted EBITDA, as presented, may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies. 1 Adjusted EBITDA is defined as net income before interest expense, income taxes, depreciation, amortization, and other adjustments.

Nevertheless, the Company believes that providing nonGAAP financial measures, such as Adjusted EBITDA and Adjusted EBITDA Margin, are important for investors and other readers of the Company’s financial statements.
