Note 15—Contingencies

On January 7, 2025, our Guadalajara subsidiary Benchmark Electronics de Mexico S. de R.L. de C.V. (Benchmark Guadalajara) received a tax assessment from the Jalisco, Mexico office of customs and taxing authorities (Servicio de Administracion Tributaria (SAT)) asserting that Benchmark Guadalajara owed approximately $12.0 million in import duties, customs penalties, fees and surcharges relating to goods imported by Benchmark Guadalajara into Mexico in the first quarter of 2016. Benchmark Guadalajara challenged the findings in the tax assessment by taking an administrative appeal with the SAT on February 19, 2025. In April 2025, Benchmark Guadalajara and SAT reached an agreement to reduce the amount levied in the tax assessment to approximately $10.1 million, and the Company accrued the expected settlement during the first quarter of 2025. Additionally, $0.6 million and $0.3 million of other related costs were incurred in connection with the matter during the second and third quarters of 2025, respectively. Benchmark Guadalajara plans to continue pursuing all available reimbursement opportunities pertaining to the assessment such as recoverable value add taxes.

On December 31, 2025, the Company’s subsidiaries Benchmark Electronics Phoenix, Inc. and Benchmark electronics Tijuana S. de R.L. C.V. (“Claimants”) commenced an arbitration action against CommScope Holding Company, Inc., CommScope, Inc., CommScope, LLC, ARRIS Technology, Inc. and their affiliated entities (“Respondents”). The Claimants contend that Respondents are liable for excess and obsolete inventory for electronic components procured at Respondents’ request and for their benefit under the

parties’ manufacturing services agreement. Efforts to settle the dispute amicably were unsuccessful and demand was made for payment for the excess and obsolete inventory the Claimants procured on Respondents’ behalf, plus carrying charges, prejudgment and post judgment interest, interim, preliminary or provisional remedies, declaratory relief, and costs. Respondents filed their answer and a counterclaim for breach of contract on January 14, 2026 and Claimants filed a motion to dismiss Respondents’ counterclaim on February 2, 2026. This dispute is in its initial legal stages. No discovery has been conducted, and thus the nature and extent of any potential recoveries, counterclaims, defenses or set offs are unknown at this time. While the Company is unable to provide any assurances as to the ultimate outcome of this matter, the Claimants intend to vigorously prosecute their claims against the Respondents.

The Company is involved in various legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company’s consolidated financial position or results of operations.
