InTest Reports Strong First Quarter 2026 Revenue of $33.9 Million, EPS of $0.06 and Adjusted EPS (Non-GAAP) of $0.16

• Revenue grew 27.2% year-over-year driven by continued diversity and strength from all end markets
• Gross margin of 45.5%, reflecting higher volume and favorable product mix
• Orders¹ of $31.8 million grew 25.4% year-over-year but declined sequentially following two consecutive quarters of record orders
• Net earnings of $0.8 million; Adjusted EBITDA (Non-GAAP)² of $3.2 million
• Raises 2026 Revenue Guidance to $130 million to $135 million on improving market conditions

InTest Corporation (NYSE American: INTT), a global supplier of innovative test and process technology solutions for use in manufacturing and testing in key target markets which include semiconductor ("Semi"), Auto/EV, Defense/Aerospace, Industrial, Life Sciences, and Safety/Security, today announced financial results for the first quarter of 2026 ended March 31, 2026.

"InTest delivered a good start to 2026, with first quarter results slightly ahead of guidance, reflecting our strong execution," stated Rich Rogoff, President and CEO. "With 69% of revenue generated from non-semiconductor end markets, we saw strong year-over-year growth across Defense/Aerospace, Life Sciences, and Auto/EV. Our Semi business improved, benefitting from shipments from our backlog¹ rather than first quarter orders. These results demonstrate the adoption of new products developed by our engineering teams and the deepening of customer relationships driven by our sales teams.

"Beyond the quarter's financial results, we continue to advance the operational priorities that will define 2026 and beyond," continued Mr. Rogoff. "Having led our M&A strategy, I have seen firsthand how our portfolio companies create value individually and, more importantly, how they are creating greater value together. My top priority is to deepen those connections by removing operational friction and accelerating cross-business product development and selling to unlock the full value of our platform. Central to this is expanding gross margin and Adjusted EBITDA (Non-GAAP)² over time, through disciplined cost management and supply-chain efficiency initiatives, while deploying capital with rigor across organic innovation, global customer expansion, and targeted M&A. Together, these actions are intended to generate stronger free cash flow and enhance shareholder returns."

First Quarter 2026 Review (see revenue by market and by segments in accompanying tables)

Revenue for the first quarter increased $1.1 million over the fourth quarter of 2025, reflecting higher Semi and Auto/EV shipments, partially offset by lower Industrial following a stronger than normal fourth quarter. Compared to the prior-year period, first quarter revenue increased $7.2 million with growth in Defense/Aerospace, Life Sciences, Auto/EV and Semi, partially offset by a decrease in Other.

Gross margin expanded by 10 basis points sequentially to 45.5%, reflecting higher volume and a favorable product mix. Compared to the prior-year period, gross margin expanded 400 basis points reflecting higher volume, favorable product mix, and manufacturing efficiency initiatives.

Operating expenses increased $0.8 million sequentially and $0.5 million year-over-year, due primarily to $0.7 million in restructuring costs associated with our CEO transition.

Net earnings for the first quarter was $0.8 million, or $0.06 per diluted share. Adjusted net earnings (Non-GAAP)² was $2.0 million, or $0.16 adjusted EPS (Non-GAAP)².

Balance Sheet and Cash Flow Review

Cash, cash equivalents and restricted cash at the end of the first quarter of 2026 was $15.7 million, down $2.4 million from the end of the fourth quarter. During the quarter, we reduced our term debt by $1.0 million from December 31, 2025, and used $3.3 million in operating activities to invest in working capital. Capital expenditures were $0.6 million in the first quarter of 2026.

At March 31, 2026, the Company had $30.0 million available under its delayed draw term loan facility and no borrowings under the $10.0 million revolving credit facility. On August 5, 2025, the Company entered into a covenant waiver agreement with its U.S.-based lender through the first quarter of 2026 in exchange for pledging cash equal to U.S. debt outstanding. At March 31, 2026, there was $2.8 million U.S.-based debt outstanding. On May 4, 2026, we amended the facility, effective as of April 30, 2026, to extend our ability to draw on the Term Note through August 28, 2026. At March 31, 2026, we were in compliance with all of the other covenants included in the Loan Agreement.

First Quarter 2026 Orders¹ and Backlog¹ (see orders by market in accompanying tables)

First quarter orders of $31.8 million decreased sequentially with lower Life Sciences, Semi, Other and Safety/Security orders partially offset by increases in Auto/EV, Industrial and Defense/Aerospace. The year-over-year increase of $6.4 million reflects strength primarily in Auto/EV and Defense/Aerospace partially offset by the decline in Semi.

Backlog at March 31, 2026, was $51.8 million, a decrease of 3.9% from December 31, 2025, and an increase of 35.5% compared to March 31, 2025. Approximately 50% of the backlog is expected to ship beyond the second quarter of 2026.

Second Quarter 2026 and Raised Full Year 2026 Outlook

Mr. Rogoff concluded, "Based on our first quarter outperformance, and improving market conditions, we are raising our full year 2026 revenue outlook to $130 million to $135 million, reflecting our confidence in the continued execution of our growth plans for the year. We remain encouraged by the underlying demand trends across our non-semiconductor markets and by early signs of improvement in our back-end Semi funnel. The strength of our backlog, the breadth of our end market exposure, and the discipline of our team give us confidence in our ability to continue to execute similarly."

For Q2 26, InTest projects revenue to be $32 million to $34 million, with gross margin of approximately 45%, and operating expenses of $13.8 million to $14.2 million, reflecting typically higher levels in the second quarter. Amortization expense is expected to be $0.7 million.

Based on full-year 2026 revenue projections between $130 million to $135 million, the Company expects gross margin of approximately 45% and operating expenses of $55 million to $57 million for the year. Amortization expense is expected to be $2.6 million and interest expense of $0.3 million. The effective tax rate for the year is expected to be approximately 18%. Capital expenditures are estimated to be approximately 1% to 2% of revenue.

The foregoing guidance is based on management's current views with respect to operating and market conditions and customers' forecasts. Actual results may differ materially from what is provided here today as a result of, among other things, the factors described under "Forward-Looking Statements" below.

Non-GAAP Financial Measures

In addition to disclosing results that are determined in accordance with generally accepted accounting practices in the United States ("GAAP"), we also disclose non-GAAP financial measures. These non-GAAP financial measures consist of adjusted net earnings (loss), adjusted earnings (loss) per diluted share ("adjusted EPS"), adjusted EBITDA, and adjusted EBITDA margin.

The Company defines these non-GAAP measures as follows:

• Adjusted net earnings (loss) is derived by adding acquired intangible amortization, restructuring costs, and the tax effect of the adjusting items, to net earnings (loss).
• Adjusted earnings (loss) per diluted share is derived by dividing adjusted net earnings (loss) by diluted weighted average shares outstanding.
• Adjusted EBITDA is derived by adding acquired intangible amortization, restructuring costs, net interest expense, income tax expense, depreciation, and stock-based compensation expense to net earnings.
• Adjusted EBITDA margin is derived by dividing adjusted EBITDA by revenue.

These results are provided as a complement to the results provided in accordance with GAAP. Adjusted net earnings (loss) and adjusted earnings (loss) per diluted share ("adjusted EPS") are non-GAAP financial measures presented to provide investors with meaningful, supplemental information regarding our baseline performance before acquired intangible amortization, and restructuring costs as management believes these expenses may not be indicative of our underlying operating performance. Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures presented primarily as a measure of liquidity as they exclude non-cash charges for acquired intangible amortization, depreciation and stock-based compensation. In addition, adjusted EBITDA and adjusted EBITDA margin also exclude the impact of restructuring costs, interest income or expense and income tax expense or benefit, as management believes these expenses may not be indicative of our underlying operating performance.

Management's Use of Non-GAAP Measures

The non-GAAP financial measures presented in this press release are used by management to make operational decisions, to forecast future operational results, and for comparison with our business plan, historical operating results and the operating results of our peers. Reconciliations from net earnings (loss) and earnings (loss) per diluted share ("EPS") to adjusted net earnings (loss) and adjusted earnings (loss) per diluted share ("adjusted EPS") and from net earnings (loss) and net margin to adjusted EBITDA and adjusted EBITDA margin, are contained in the tables below.

Management believes these Non-GAAP financial measures are important in evaluating our performance, results of operations, and financial position. We use non-GAAP financial measures to supplement our GAAP results to provide a more complete understanding of the factors and trends affecting our business. Non-GAAP measures as presented in this press release may differ from and may not be comparable to similarly titled measures used by other companies.

Key Performance Indicators

In addition to the foregoing non-GAAP measures, management uses orders and backlog as key performance metrics to analyze and measure the Company's financial performance and results of operations. Management uses orders and backlog as measures of current and future business and financial performance, and these may not be comparable with measures provided by other companies. Orders represent written communications received from customers requesting the Company to provide products and/or services. Backlog is calculated based on firm purchase orders we receive for which revenue has not yet been recognized. Management believes tracking orders and backlog are useful as they are often leading indicators of future performance. In accordance with industry practice, contracts may include provisions for cancellation, termination, or suspension at the discretion of the customer.

Given that each of orders and backlog are operational measures and that the Company's methodology for calculating orders and backlog does not meet the definition of a non-GAAP measure, as that term is defined by the U.S. Securities and Exchange Commission, a quantitative reconciliation for each is not required or provided.
