First Quarter 2026 Results (compared with the prior-year period, unless noted otherwise)

Growth in sales was driven by the Aerospace segment’s continued strength in demand primarily from the Commercial Transport market. Aerospace sales increased $22.4 million, or 11.7%, while Test Systems sales grew $2.2 million, or 15.4%.

Gross profit increased $14.3 million to $75.1 million, or 32.6% of sales, an improvement over gross margin of 29.5% in the comparator quarter. Gross profit growth and margin expansion were primarily attributable to higher volume, improved productivity, and a $2.8 million catch-up of profit on the MV-75 program based on revised program estimates. This was partially offset by a $1.7 million increase in tariff expenses. In the prior year, first quarter consolidated sales and gross profit was negatively impacted by a $1.9 million revision of estimated costs to complete a long-term mass transit contract in the Test Systems segment.

Selling, general and administrative expenses (“SG&A”) decreased $0.8 million. Litigation-related expenses were down $1.2 million, and the prior-year period included a $6.2 million reserve adjustment to the damage award relating to the patent infringement dispute in the UK. Appeals to the UK damage award are scheduled to be heard in July 2026. These decreases were mostly offset by higher wages and benefits, higher incentive-based compensation expenses driven by increased profitability, and incremental expenses related to the acquired BMA business. R&D was up $1.0 million reflecting the timing of projects.

Operating margin expanded 540 basis points and adjusted operating margin2 expanded 180 basis points as a result of higher volume and improved productivity in the Aerospace segment, coupled with savings from the recent Test Systems cost rationalization activities.

Interest expense was down $0.8 million, or 25.8%, on lower rates following the September 2025 refinancing activities. Tax benefit in the quarter of $0.8 million was related to a $2.7 million discrete adjustment for the expected benefit of a stock-based compensation deduction, a valuation allowance reversal, and research and development costs expected to be expensed. Tax expense in

the prior year period was partially offset by a $1.1 million discrete adjustment to reverse certain federal and state deferred tax liabilities.

Consolidated net income of $0.67 per diluted share improved from $0.26 per diluted share in the prior-year period from stronger operating profit, lower interest expense and lower tax. Adjusted EBITDA2 increased 23.3% to $37.9 million, and adjusted EBITDA margin2 expanded 150 basis points to 16.4% of consolidated sales.

Record bookings of $290.4 million in the quarter resulted in a book-to-bill ratio of 1.26:1. For the trailing twelve months, bookings totaled $935.1 million and the book-to-bill ratio was 1.05:1. Backlog at the end of the quarter was $734.3 million, the highest in the Company’s history.

Aerospace Segment Review (compared with the prior-year period, unless noted otherwise)

Aerospace segment sales of $213.8 million increased $22.4 million, or 11.7%. Sales in the Commercial Transport market increased $18.9 million, or 13.7%. Growth was primarily related to increased demand for seat motion and lighting and safety products. General Aviation sales increased $6.2 million, or 40.7%, to $21.4 million due to higher inflight entertainment & connectivity (“IFEC”) product sales to the VVIP market. Military Aircraft sales remained consistent with the prior-year period. Other sales decreased $2.9 million as the Company has wound down its non-core contract manufacturing arrangements.

Aerospace segment operating profit of $35.3 million, or 16.5% of sales, improved over the prior-year period reflecting the leverage gained on higher volume, improving production efficiencies, the cumulative catch-up of profit on the MV-75 program based on revised program estimates, and a $7.0 million decrease in litigation-related expenses and legal reserve adjustments related to the UK patent dispute previously discussed. Adjusted Aerospace operating profit2 increased 20.0% to $37.2 million, or 17.4% of sales, a 120-basis point expansion over the comparator quarter.

Aerospace bookings were $264.4 million for a book-to-bill ratio of 1.24:1. Record backlog for the Aerospace segment was $651.4 million at quarter end.

Mr. Gundermann commented, “Our Aerospace business had a solid first quarter with our second-highest quarterly sales total, trailing only the preceding fourth quarter. Strong sales led to a 16.5% operating margin. Market demand for our products remains strong and we are well positioned to set new records in the coming periods.”

Test Systems Segment Review (compared with the prior-year period, unless noted otherwise)

Test Systems segment sales of $16.8 million were up $2.2 million from the comparator quarter in 2025. Segment sales in the prior-year period were negatively impacted by a $1.9 million revision of estimated costs to complete a certain long-term mass transit Test contract reducing revenue recognized in the period.

Test Systems segment operating profit was $0.4 million, compared with an operating loss of $2.2 million in the first quarter of 2025. Test Systems profitability, while improving, continues to be negatively affected by mix and under absorption of fixed costs at current volume levels.

Bookings for the Test Systems segment in the quarter were $26.1 million. The book-to-bill ratio for the quarter was 1.55:1. Backlog for the Test Systems segment was $83.0 million at quarter end.

Mr. Gundermann commented, “Results in our Test business continue to confirm that our significant cost-cutting and efficiency actions have been effective, and we expect results to improve significantly as the radio test program for the U.S. Army begins. We understand that a production

award is on track to be issued in the coming weeks, with the production phase of the program accelerating in the second half of the year.”

Balance Sheet and Liquidity

Cash provided by operations in the first quarter of 2026 was $10.6 million, reflecting higher cash earnings offset by higher working capital requirements, including higher inventory levels to support anticipated revenue growth in the coming quarters. Capital expenditures in the quarter were $11.2 million. Elevated capital expenditures reflect necessary catch-up investments on previously deferred spending as well as the consolidation of operations and capacity improvement in a new Seattle facility. The Company expects to be free cash flow positive for the remainder of the year.

Long-term debt was relatively unchanged at quarter-end at $334.9 million. The Company had available liquidity of $231.8 million at quarter-end, including $19.1 million in available cash.

2026 Outlook

Astronics expects 2026 revenue for the year to be in the range of $970 million to $1 billion, which would surpass the record level sales of 2025. The midpoint of the revised range would be a 14% increase over 2025 sales.

Record backlog at the end of the first quarter was $734.3 million, of which approximately 81% is expected to drive revenue over the next twelve months. Mr. Gundermann concluded, “We expect second quarter sales of $245 million to $250 million, which will be a new record for the Company, and we expect our revenue rate in the second half to rise further from there. Demand remains strong for our products and capabilities, and all indications point to a very strong 2026 for our Company.”

Planned capital expenditures in 2026 are expected to be in the range of $40 million to $45 million driven largely by costs associated with the Seattle operation consolidation, which will conclude in the second quarter. In addition, the Company is in the early phases of implementing a new global resource planning system. Astronics expects to spend approximately $15 million to $17 million on this project in 2026, excluding reallocated internal operating costs. Approximately $2 million to

$3 million of the investment will be incremental operating expense with the remainder to be capitalized and reported as a cash outflow from operations. The total cost of the project over five years, excluding reallocated internal operating expenses, is expected to be approximately

$35 million to $40 million of which $25 million is expected to be capitalized.

Use of Non-GAAP Financial Metrics and Additional Financial Information

In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, Astronics provides Adjusted Non-GAAP information as additional information for its operating results. References to Adjusted Non-GAAP information are to non-GAAP financial measures.

Astronics management uses these measures for reviewing the financial results of Astronics for budget planning purposes and for making operational and financial decisions. Management believes that providing these non-GAAP financial measures to investors, as a supplement to GAAP financial measures, help investors evaluate Astronics core operating and financial performance and business trends consistent with how management evaluates such performance and trends.

Adjusted diluted earnings per share7 $ 0.59 $ 0.44

Adjusted Net Income and Adjusted Diluted EPS are defined as net income and diluted EPS as reported, adjusted for certain items, including amortization of intangibles, and also adjusted for a normalized tax rate. Adjusted Net Income and Adjusted Diluted EPS are not measures determined in accordance with GAAP and may not be comparable with the measures used by other companies. Nevertheless, the Company believes that providing non-GAAP financial measures, such as Adjusted Net Income and Adjusted Diluted EPS, are important for investors and other readers of the Company’s financial statements and assists in understanding the comparison of the current periods’ net income and diluted EPS to the historical periods’ net income and diluted EPS, as well as facilitates a more meaningful comparison of the Company’s net income and diluted EPS to that of other companies. The Company believes that presenting Adjusted Diluted EPS provides a better understanding of its earnings power inclusive of adjusting for the non-cash amortization of intangible assets, reflecting the Company’s strategy to grow through acquisitions as well as organically.

6 Applies a normalized tax rate of 25% to GAAP pre-tax income and non-GAAP adjustments above, which are each pre-tax.

7 In addition to incremental shares from stock awards, weighted average diluted shares for the quarter ended April 4, 2026 reflects 0.992 million assumed shares underlying the premium on the 0% convertible bonds, to the extent the average stock price for the quarter ($72.38) exceeded the $54.87 conversion price. Note that because of the capped call, there is no effective dilution to shareholders resulting from the 0% convertible bonds unless and until the share price exceeds $83.41. The diluted EPS calculation for the quarter ended April 4, 2026 excludes the effect of the 5.5% Notes because the effect is anti-dilutive. The diluted EPS calculation for the quarter ended March 29, 2025 reflects 7.208 million assumed shares underlying the 5.5% convertible bonds.
