(all comparisons versus the prior year period)

MANAGEMENT COMMENTARY

“Fiscal 2025 was another transformational year for our entire organization, one highlighted by strong financial results and meaningful progress across our strategic priorities, consistent with our long-term value creation plan,” stated Shahram Askarpour, Chief Executive Officer of Innovative Aerosystems. “This year, we made targeted investments to drive sustainable, profitable growth, including the expansion of our Exton manufacturing facility, the strengthening of our engineering capabilities, enhancements to our sales organization, and advancements in our digital and data infrastructure. Today, we are introducing our longer-term target of $250 million in revenue and 25-30% Adjusted EBITDA margin by fiscal 2029.”

“We ended the fiscal year on a strong note, with fourth quarter sales increasing 45% year-over-year to $22.2 million,” continued Askarpour. “The combined benefit of increased throughput from other client programs, a more favorable sales mix driving higher gross margins, and improved operating leverage resulted in fiscal fourth quarter Adjusted EBITDA of $9.6 million, an increase of 71.1% versus the prior year, together with a 670-basis point improvement in Adjusted EBITDA margin to 43% compared to the prior year.”

“Our industry-unique products and systems-integration expertise have positioned IA as a preferred partner in fleet modernization and retrofit programs,” continued Askarpour. “With in-house design, manufacturing, installation, and support capabilities, we deliver end-to-end solutions that reduce complexity and accelerate deployment for operators worldwide. A key driver of our next phase of growth is our new Liberty Flight Deck (LFD), a customer-centric, fully customizable design that can be tailored for most aircraft types, including large passenger and cargo planes, business aviation and military applications. In October 2025, at the National Business Aviation Association, we unveiled the LFD, which was well received by current and potential customers.”

“As we enter fiscal 2026, we’re well-positioned to benefit from the foundational investments we’ve made across the organization during the last three fiscal years,” concluded Askarpour. “Our team continues to execute at a high level, end-market trends remain favorable and our financial position is solid, all of which position us to deliver another year of profitable growth as we look to fiscal 2026. We are energized by the opportunities ahead of us and remain committed to advancing our long-term strategic initiatives, while maintaining a steadfast focus on creating value for our shareholders.”

STRATEGIC UPDATE

The IA Next value creation framework prioritizes profitable growth, sustained operational excellence, and disciplined capital allocation as key drivers of long-term value creation. This framework is the mechanism by which IA intends to achieve its long-term target of $250 million in revenue and Adjusted EBITDA margin of between 25% to 30%, which includes contribution from organic growth as well as strategic acquisitions. The Company’s strong fiscal 2025 results are early evidence of execution on these key strategic initiatives.

Key accomplishments during fiscal year 2025 and priorities for fiscal year 2026 are as follows:

Commercial Focus

Operational Excellence

Disciplined Capital Allocation

FOURTH QUARTER FISCAL 2025 PERFORMANCE

Fourth quarter revenue was $22.2 million, an increase of 44.6% compared to the same period last year driven by momentum in military programs and revenue synergies from acquired Honeywell product lines, as well as incremental revenues from recently acquired platforms.

Gross profit was $14.1 million during the fourth quarter of 2025, up 64.8% from gross profit of $8.5 million in the fourth quarter of last year. The improvement was driven by strong revenue growth and a more favorable revenue mix, partially offset by higher depreciation and amortization expense resulting from the Honeywell acquisitions and continued investments in growth initiatives.

Fourth quarter 2025 gross margin was 63.2%, up from 55.4% during the fourth quarter last year, as the Company benefitted from a more favorable sales mix.

Fourth quarter 2025 operating expenses were $5.8 million, compared to $4.2 million in the fourth quarter of last year, reflecting incremental expenses associated with Honeywell acquisitions, including $0.3 million of amortization expense and $1.3 million in employee related costs to support the Company’s strategic goals.

Net income was $7.1 million, or $0.39 per diluted share during the fourth quarter, compared to net income of $3.2 million, or $0.18 per share in the fourth quarter of last year.

Adjusted EBITDA was $9.6 million during the fourth quarter, up from $5.6 million in the fourth quarter of last year.

During the fourth quarter, the Company recognized a $1.8 million gross benefit related to the Employee Retention Tax Credit (“ERTC”), a refundable payroll tax credit enacted under the CARES Act and subsequent legislation. The benefit relates primarily to qualifying wages paid during prior periods and was recognized upon confirmation of eligibility.

New orders in the fourth quarter of fiscal 2025 were $27.2 million and backlog as of September 30, 2025 was $77.4 million. The backlog includes committed purchases and excludes additional orders from the Company’s OEM customers under long-term programs, including Pilatus PC-24, Textron King Air, Boeing T-7 Red Hawk, Boeing KC-46A and Lockheed Martin F-16.

BALANCE SHEET, LIQUIDITY AND FREE CASH FLOW

As of September 30, 2025, IA had total debt of $24.4 million. Cash and cash equivalents as of September 30, 2025, were $2.7 million, resulting in net debt of $21.7 million. Despite elevated capital expenditures during the fourth quarter of 2025 relating to the Exton facility expansion, net debt declined $1.0 million during the quarter, reflecting strong operating results as well as disciplined financial management. As of September 30, 2025, IA had total available liquidity of $77.7 million, including cash of $2.7 million and availability of $75 million under its credit line.

Cash flow provided by operations was $13.3 million during fiscal year 2025, compared to $5.8 million last fiscal year. Capital expenditures, primarily the costs associated with the Exton facility expansion, during fiscal year 2025 were $6.5 million, versus $0.7 million in the year-ago period. Free cash flow was $6.8 million during fiscal year 2025 versus $5.1 million last fiscal year.

NON-GAAP FINANCIAL MEASURES

EBITDA, Adjusted EBITDA, Adjusted Net Income, Adjusted Diluted Earnings Per Share (“EPS”), Adjusted Net Cash provided by operating activities (“free cash flow”) and net debt are not measures of financial performance under GAAP and should not be considered substitutes for GAAP measures, net income (for EBITDA and Adjusted EBITDA), diluted earnings per share (for Adjusted diluted EPS) or net cash provided by operating activities (for free cash flow), which the Company considers to be the most directly comparable GAAP measures. These non-GAAP financial measures have limitations as analytical tools, and when assessing the Company’s operating performance, readers should not consider these non-GAAP financial measures in isolation or as substitutes for net income, diluted earnings per share, net cash provided by operating activities or other consolidated income statement data prepared in accordance with GAAP. Other companies in the Company’s industry may define or calculate these non-GAAP financial measures differently than the Company does, and accordingly, these measures may not be comparable to similarly titled measures used by other companies.

The Company defines EBITDA as net income before interest, taxes, depreciation, and amortization. The Company believes EBITDA to be relevant and useful information to their investors because it provides additional information in assessing the Company’s financial operating results. The Company’s management uses EBITDA in evaluating operating performance, ability to service debt, and ability to fund capital expenditures and pay dividends. However, EBITDA has certain limitations in that it does not reflect the impact of certain expenses on the Company’s consolidated statements of income, including interest expense, which is a necessary element of the Company’s costs because the Company has borrowed money in order to finance operations, income tax expense, which is a necessary element of costs because taxes are imposed by law, and depreciation and amortization, which are necessary elements of costs because the Company uses capital assets to generate income. EBITDA should be considered in addition to, and not as a substitute for, or superior to, operating income, net income or other measures of financial performance prepared in accordance with U.S. GAAP. Furthermore, the Company’s definition of EBITDA may not be comparable to similarly titled measures reported by other companies. Below is our reconciliation of EBITDA to U.S. GAAP net income.

The Company defines Adjusted EBITDA as net income before interest, taxes, depreciation, amortization, transaction-related acquisition and integration expenses, and non-recurring items. The Company believes that Adjusted EBITDA is an appropriate measure of operating performance because it eliminates the impact of expenses that do not relate to ongoing business performance, and that the presentation of this measure enhances an investor’s understanding of its financial performance.

Adjusted EBITDA has important limitations as an analytical tool. For example, Adjusted EBITDA:

Free cash flow is calculated as net cash provided by operating activities less capital expenditures. The Company believes that free cash flow is an important financial measure for use in evaluating financial performance because it measures the Company’s ability to generate additional cash from its business operations.

Net debt is calculated as total debt, excluding debt issuance costs and adjusted for cash, and Leverage Ratio is calculated as trailing 12 months Adjusted EBITDA divided by Net Debt. The Company believes that Net debt and Leverage Ratio are important financial measures for use in measuring the Company’s financial performance relative to its level of debt.

A reconciliation of each non-GAAP measure to the most directly comparable GAAP measure is set forth below.
