Item 1.01			Entry into a Material Definitive Agreement

On October 24, 2025 (the “Effective Date”), Littelfuse, Inc., a Delaware corporation (“Littelfuse” or the “Company”), entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Basler Holdings, LLC (“Seller”), pursuant to which the Company has agreed to acquire all of the issued and outstanding membership interests of Basler Electric Company (“Basler”), as further described below.

Transaction Overview

On the terms and conditions set forth in the Purchase Agreement, the Company has agreed to purchase all of the issued and outstanding membership interests of Basler for a purchase price of approximately $350 million in cash, subject to certain adjustments after closing (the “Transaction”).

The completion of the Transaction is subject to certain customary closing conditions, including (i) expiration or termination of any waiting periods (and any extensions thereof) applicable under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (ii) the absence of any order that enjoins, prohibits or otherwise prevents the consummation of the Transaction; (iii) the absence of any actions instituted against a party before any governmental authority that could reasonably be expected to enjoin, prohibit or otherwise prevent the consummation of the Transaction; and (iv) the receipt of certain required consents, including approvals of specified governmental authorities having been obtained. Each party’s obligation to consummate the Transaction is also subject to certain additional closing conditions, including the material accuracy of the other party’s representations and warranties contained in the Purchase Agreement, and the other party’s compliance in all material respects with its covenants and agreements contained in the Purchase Agreement.

The Purchase Agreement contains customary representations, warranties and covenants by each party that are subject, in some cases, to specified exceptions and qualifications contained in the Purchase Agreement. Among other things, Seller has agreed (i) to use commercially reasonable efforts to conduct Basler’s business in the ordinary course of business in all material respects between the execution of the Purchase Agreement and the closing of the Transaction, and (ii) not to engage in certain transactions, such as equity issuances or dispositions, incurrence of indebtedness beyond an agreed threshold, or acquisitions between the execution of the Purchase Agreement and the closing of the Transaction, except with the written consent of the Company.

Each of the parties is required to use their respective commercially reasonable efforts to consummate the Transaction. Without limiting the foregoing, each party must use its commercially reasonable efforts to take all actions necessary to obtain the required consents from antitrust authorities, including contesting any action or proceeding instituted by a governmental authority that prohibits, prevents or restricts the consummation of the Transaction.

Both the Company and Seller have agreed, following the closing, to indemnify the other party for losses arising from certain breaches of the Purchase Agreement and for certain other liabilities, subject to certain limitations, and the Company has obtained a representations and warranties insurance policy in connection with certain breaches of representations and warranties made by Basler.

In connection with the entry into the Purchase Agreement, on the Effective Date, the Company entered into Non-Compete, Non-Solicitation, Indemnification, Resignation and Release Agreements (the “Non-Compete Agreements”) with the Original Owners and Original Shareholders (as each term is defined in the Purchase Agreement). Among other things, the Non-Compete Agreements include certain restrictive covenants, resignation and indemnification obligations, and release from claims against the Company.

The Purchase Agreement has been included to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Seller, Basler, or any of their respective affiliates or businesses. The Purchase Agreement contains representations and warranties that are the product of negotiations among the parties thereto and that the parties made to, and solely for the benefit of, each other as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure schedules delivered in connection with the Purchase Agreement. The representations and warranties may have been made for the purpose of allocating contractual risk between the parties to the Purchase Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company, Seller, Basler, any of their respective subsidiaries or affiliates or businesses.

The foregoing description of the Purchase Agreement and Non-Compete Agreements does not purport to be complete and is qualified in its entirety by reference to the full texts of the Purchase Agreement and Form of Non-Compete Agreement, which are filed herewith as Exhibits 2.1 and 10.1, respectively, and are incorporated herein by reference.
