Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Principal Officers.

On October 28, 2025, Kulicke and Soffa Industries, Inc. (the "Company") announced that due to health reasons, Dr. Fusen Chen has informed the Company’s Board of Directors (the “Board”) that he will retire as President and Chief Executive Officer of the Company and as a member of the Board, effective December 1, 2025 (the “Effective Date”).

Also, on October 28, 2025, the Board appointed Lester Wong, the Company’s current Executive Vice President and Chief Financial Officer, as the Company’s Interim Chief Executive Officer (“Interim CEO”). The Board will conduct a search for a permanent successor among external and internal candidates.

As Dr. Chen transitions from his role and in leading up to his retirement as of the Effective Date, Dr. Chen will support Lester Wong in ensuring a smooth transition and handover. Following the Effective Date, Dr. Chen will serve as an advisor to the Board for a 12-month period from the Effective Date (the “Term”). As payment for his advisory services, Dr. Chen will receive a fee of US$75,000 per month during the Term. If Dr. Chen is terminated by the Company before the end of the Term, other than “for cause”, Dr. Chen will be entitled to continue to receive these monthly payments as if he had remained continuously engaged as an advisor to the Board throughout the Term.

Pursuant to the terms of the Company’s Incentive Compensation Plan, Dr. Chen will receive a pro-rated, annual cash bonus (based on his target opportunity at the Effective Date) for the fiscal year in which he retired. Outstanding performance share unit awards granted by the Company, which are valid and effective as of the Effective Date, shall remain eligible for vesting, and other unvested restricted stock unit awards shall be automatically forfeited as of the Effective Date. The Company will provide Dr. Chen with health insurance coverage for a period of 18 months from the Effective Date.

Mr. Wong, 59, has been the Company’s Chief Financial Officer since December 2018, and was promoted to Executive Vice President, from Senior Vice President, on January 1, 2022. Mr. Wong will also continue to serve in his current role as the Company's Executive Vice President and Chief Financial Officer.

In connection with Mr. Wong’s appointment as Interim CEO, the Board approved a monthly cash stipend of S$35,000, to be paid for each month of Mr. Wong’s service as Interim CEO through the date on which a new Chief Executive Officer is appointed by the Board. Where applicable, Mr. Wong will be paid pro-rated for any month of partial service based on the number of days in such month in which Mr. Wong serves as the Interim CEO.

Additionally, Mr. Wong will be granted S$600,000 in restricted stock units on the Effective Date (the “Grant Date”), which shall vest in full on the 1-year anniversary of the Grant Date, subject to his continued employment with the Company through such date. If Mr. Wong is terminated by the Company without Cause or if Mr. Wong resigns with Good Reason (as each term is defined in the Company’s Executive Severance Pay Plan), such restricted stock units shall vest in full upon such termination date.

Mr. Wong has no family relationships or related party transactions with the Company that would require disclosure under Items 401(d) and 404(a) of Regulation S-K in connection with his appointment as Interim Chief Executive Officer.
