Management to Report Second Quarter Results on Monday, August 10, 2026

InTest Corporation (NYSE:INTT), a global supplier of innovative test and process technology solutions for use in manufacturing and testing in key target markets which include Semiconductor, Automotive/EV, Defense/Aerospace, Industrial, Life Sciences, and Safety/Security, today announced estimated revenue, gross margin, and operating expenses for the second quarter ended June 30, 2026, based on management’s preliminary review. The Company also announced that it intends to revise an overstatement of gross margin in its previously reported financial results for the first quarter ended March 31, 2026, and that no amendment of its previously filed reports is required.

Preliminary Second Quarter 2026 Results

The financial results in this press release are preliminary and subject to completion of the Company’s financial closing procedures. Actual results may vary materially from these preliminary financial results due to the completion of the Company’s financial closing procedures and other developments or information that may arise between now and the time of the finalization of the Company’s financial results for the three and six months ended June 30, 2026.

For the second quarter, revenue is expected to be approximately $35 million, gross margin is expected to be approximately 40%, and operating expenses are estimated to be $13.9 million. These figures compare to management’s second quarter guidance of $32 million to $34 million, approximately 45%, and $13.8 million to $14.2 million for revenue, gross margin, and operating expenses, respectively.

Second quarter revenue exceeded prior guidance range, driven by strengthening demand across several end markets. The shortfall to gross margin guidance for the second quarter is due to:

Lower than expected delivered gross margin on projects shipped by Alfamation. This was driven by unfavorable project mix and accounted for approximately 340 basis points of the total shortfall of about 500 basis points; and,
A delay in shipping approximately $2 million of ITS revenue into the third quarter due to a supply chain disruption which negatively impacted volume for the Environmental Technologies segment and accounted for approximately 160 basis points of the total shortfall of about 500 basis points.

Revision of First Quarter 2026 Financial Statements

Implementation issues with a new ERP system at Alfamation that went live in the first quarter contributed to overstated inventory and gross margin in the first quarter of 2026. The Company completed a physical inventory count within Alfamation’s operations as of June 30, 2026, and, based on extensive analysis of Alfamation’s inventory costs on projects shipped during the first and second quarters, management has determined that first quarter total consolidated gross profit was overstated by approximately $750,000. This equates to a 220-basis point downward revision to the Company’s previously reported Q1 gross margin. The Company has also determined that this accounting error is not material for the quarter ended March 31, 2026; however, correcting the cumulative effect of the error in the current period would be material to the current-period results. As a result, the Company intends to revise financial results for the first quarter to include an approximately $750,000 reduction in inventory and increase to cost of sales as of and for the quarter ended March 31, 2026. While the Company believes that the accounting error was not material to the Q1 financial results, it was not able to determine that the error could not have been greater. As a result, the Company expects to report a material weakness in its internal control over financial reporting. The Company believes that the material weakness has now been remediated and fully expects to be able to demonstrate operating effectiveness by fiscal year-end.

Revised Full Year Outlook

The Company now expects full year 2026 revenue to be $135 million to $140 million compared to its prior revenue guidance range of $130 million to $135 million, reflecting its year-to-date performance, strengthening customer demand, and anticipated order activity in the second half of the year across several of its end markets. The Company now expects full year gross margin of approximately 43% (approximately 41.8% year-to-date), slightly below its prior guidance of 45%, reflecting the reductions in Alfamation’s gross margin for the first and second quarters of the year partially offset by an expectation of an improved mix of higher-margin revenue in the second half of the year compared to the first half. Full year operating expense guidance remains unchanged at $55 million to $57 million, amortization expense and interest expense remain unchanged at $2.6 million and $0.3 million, respectively, the effective tax rate is expected to remain at approximately 18%, and capital expenditures are estimated to remain at approximately 1% to 2% of revenue.

Management Commentary:

"While the implementation of a new ERP system is generally understood to be challenging, it is nevertheless disappointing that we didn't realize sooner that Alfamation’s gross margin was overstated. In addition to revisions to first quarter gross margin, we are also making downward adjustments to our estimated gross margins on Alfamation orders to be delivered in the second half of the year," stated Duncan Gilmour, Chief Financial Officer.

Rich Rogoff, President and CEO, added, "As I shared on my first earnings call last quarter, my top priority is instilling the operational discipline that keeps our systems and processes in step with the Company's growth. Addressing the reporting issue at Alfamation sits squarely within that mandate, and it has my full attention. Looking ahead, strengthening demand in our sales funnel across our end markets has led us to raise our full-year 2026 revenue outlook. End markets demand remains strong, and driving operating leverage and adjusted EBITDA expansion continues to be my focus."
