Item 5.02(b).

On February 3, 2025, Balu Balakrishnan notified the Company that he intends to retire from his position as president and chief executive officer. His decision to retire was not the result of any dispute or disagreement with the company or the board. Mr. Balakrishnan will continue to serve as president and chief executive officer until such time that the company’s board of directors appoints a new chief executive officer.  The company’s board of directors has retained an executive search firm to assist in identifying its next chief executive officer. Mr. Balakrishnan will continue to serve as Chairman of the Board during this transition and thereafter is expected to remain a member of the board of directors.

A copy of the Company’s press release announcing Mr. Balakrishnan’s retirement is attached hereto as Exhibit 99.1.
