ITEM 9A. CONTROLS AND PROCEDURES.
Evaluation of Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in its reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, the Company recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and the Company is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
As required by SEC Rule 15d-15(b), the Company carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to SEC Rule 13a-15 and based upon the updated framework in Internal Control — Integrated Framework (2013), as of the end of the period covered by this Annual Report on Form 10-K. The Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of December 27, 2025.
Management’s Report on Internal Control over Financial Reporting
Section 404 of the Sarbanes-Oxley Act of 2002 requires management to include in this Annual Report on Form 10-K a report on management’s assessment of the effectiveness of the Company’s internal control over financial reporting, as well as an attestation report from the Company’s independent registered public accounting firm on the effectiveness of the Company’s internal control over financial reporting. Management is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f), based on the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway

Commission (“the COSO Framework). The Company’s internal control system was designed to provide reasonable assurance to its management and the Board of Directors regarding the preparation and fair presentation of published financial statements.
The Company’s management, including its Principal Executive Officer and Principal Financial Officer, assessed the effectiveness of the Company’s internal control over financial reporting as of December 27, 2025, based upon the updated framework in Internal Control — Integrated Framework (2013). Based on this assessment, the Company’s management concluded that, as of December 27, 2025, the Company’s internal control over financial reporting was effective.
On December 11, 2025, the Company completed the acquisition of Basler, as discussed in Note 2 – Acquisitions. Management has excluded Basler's internal controls over financial reporting from its assessment of the effectiveness of internal controls over financial reporting as of December 27, 2025. Basler’s net sales and total assets represent approximately 0.2% and 9%, respectively, of the consolidated financial statement amounts as of and for the fiscal year ended, December 27, 2025.
The Company’s independent registered public accounting firm, Deloitte & Touche LLP, has audited the consolidated financial statements included in this Annual Report on Form 10-K issued and have issued an attestation report on our internal control over financial reporting as of December 27, 2025.
Changes in Internal Control over Financial Reporting
During the fiscal year of 2025, the Company completed a number of initiatives and actions to address the previously reported material weaknesses, which included the following:
Control Environment
• The Company replaced key finance and operational roles at certain non-U.S. manufacturing locations, and recruited personnel with appropriate internal controls experience and accounting knowledge commensurate with our accounting and reporting requirements;
• The Company completed the redesign of the regional operations and finance organizational structures; and
• New corporate policies and procedures have been adopted and disseminated along with appropriate training provided to strengthen the control environment and inventory management oversight.
Control Activities
• Key monitoring controls have been designed and implemented for full physical counts, inventory storage locations, and over the completeness and accuracy of excessive and obsolete inventory calculations; and
• Full physical inventory observations, facilitated by independent counters, have been performed in certain non-U.S. locations in the second, third and fourth quarters of the fiscal year 2025.
After implementing the above initiatives and actions, the Company completed the necessary testing and concluded that the material weaknesses outlined above have been remediated as of December 27, 2025.
Other than the changes described above to address and remediate the previously disclosed material weaknesses, there has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls and Procedures
There are inherent limitations to the effectiveness of any system of internal control over financial reporting. Accordingly, even an effective system of internal control over financial reporting can only provide reasonable assurance with respect to financial statement preparation and presentation in accordance with accounting principles generally accepted in the United States of America. Our internal controls over financial reporting are subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, and the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may be inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time.

We have two equity compensation plans that have been approved by our stockholders: the Littelfuse, Inc. Long-Term Incentive Plan that was approved by our stockholders at the April 2017 annual stockholder meeting, as amended by an amendment approved by our stockholders at the April 2023 annual stockholders meeting, and the Deferred Compensation Plan for Non-Employee Directors that was approved by our stockholders at the May 2005 annual stockholder meeting.
Pursuant to our acquisition of IXYS on January 17, 2018, we assumed four equity compensation plans that have not been approved by our stockholders and pursuant to which we may continue to grant equity awards: IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan (together, the "IXYS Plans"). We also assumed two expired equity compensation plans that have not been approved by our stockholders and pursuant to which we no longer have outstanding equity awards: the Zilog, Inc. 2002 Omnibus Stock Incentive Plan and Zilog, Inc. 2004 Omnibus Stock Incentive Plan (together, the "Zilog Plans"). The IXYS Corporation 2009 Equity Incentive Plan expired in June 2019; the IXYS Corporation 2011 Equity Incentive Plan expired

Table of Contents
in June 2021; the IXYS Corporation 2013 Equity Incentive Plan expired in June 2023; and equity awards remain outstanding under those plans.
Information about our equity compensation plans that were either approved or not approved by our stockholders as of December 27, 2025, was as follows:
Plan Category Number of securities to
be issued upon exercise of outstanding options, warrants and rights Weighted-average exercise price of outstanding options, warrants, and rights
(1) Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in the first column)
Equity compensation plans approved by security holders 614,508 (2) $136.87 771,172 (4)
Equity compensation plans not approved by security holders 92,437 (3) $24.81 91,214 (5)
Total 706,945 $122.22 862,386
(1) The weighted average exercise price does not take into account the shares issuable upon the vesting of outstanding restricted stock units, performance share units, and any related dividend equivalents, as these awards do not have an exercise price.
(2) Includes 160,147 shares reserved for issuance upon vesting of outstanding restricted stock units and related dividend equivalents, 73,380 shares issuable upon vesting of outstanding performance share units and related dividend equivalents, and 380,981 outstanding stock options granted under the Littelfuse, Inc. Long-Term Incentive Plan.
(3) Includes 77,620 shares reserved for issuance upon vesting of outstanding restricted stock units and related dividend equivalents under the IXYS Plans and 14,817 outstanding stock options granted under the IXYS Plans and Zilog Plan. Below is a brief description of the material features of the compensation plans acquired pursuant to the acquisition of IXYS Corporation.
(4) Includes 727,438 shares that remain available for future issuance under the Littelfuse, Inc. Long-Term Incentive Plan and 43,734 shares that remain available for future issuance under the Deferred Compensation Plan for Non-Employee Directors.
(5) Includes 91,214 shares that remain available for future issuance under the IXYS Corporation 2016 Equity Incentive Plan.
IXYS Plans
In connection with the acquisition of IXYS, we assumed the IXYS Corporation 2009 Equity Incentive Plan, IXYS Corporation 2011 Equity Incentive Plan, IXYS Corporation 2013 Equity Incentive Plan, IXYS Corporation 2016 Equity Incentive Plan and outstanding unvested stock options originally granted by IXYS Corporation under the IXYS Plans that were held by continuing employees. At the time of the acquisition of IXYS Corporation, these awards were converted to Littelfuse stock options, with adjustments made to the exercise price of the stock options and the number of shares subject to stock options as agreed upon in the Acquisition Agreement. These unvested options vest in accordance with their original terms, generally vesting in equal annual installments over a four-year period from the original grant date. The options, once granted, generally expire ten years from the date of grant. Under the IXYS Plans, we may grant to former employees of IXYS Corporation or its subsidiaries restricted stock awards, RSUs, stock options and stock appreciation rights with an exercise price that is no less than the fair market value on the date of grant. Equity awards granted under the IXYS Plans following the acquisition have been on similar terms and consistent with grants made pursuant to the Littelfuse, Inc Long-Term Incentive Plan. The IXYS Corporation 2009, 2011, 2013 Equity Incentive Plans expired in June 2019, June 2021 and June 2023, respectively, with no additional grants made after the expiration date. As of December 27, 2025, 91,214 shares remained available for issuance under the IXYS Plans.
Zilog Plans
In connection with the acquisition of IXYS Corporation, we assumed the Zilog, Inc. 2004 Omnibus Stock Incentive Plan and outstanding stock options originally granted by IXYS Corporation under the Zilog Plan that were held by continuing employees of Zilog. At the time of the acquisition of IXYS Corporation, these awards were converted to Littelfuse stock options, with adjustments made to the exercise price of the stock options and the number of shares subject to stock options as agreed upon in the Acquisition Agreement. These options vested in accordance with their original terms, generally in equal annual installments over a four-year period from the original grant date. The options generally expire ten years from the date of grant. The Zilog 2004 Omnibus Stock Incentive Plan expired in February 2014 and no additional grants have been made thereunder. Therefore, as of December 27, 2025, no shares remain available for issuance of new awards under the Zilog Plan and no stock options remain outstanding.
