(a) On July 23, 2025, Kenneth W. Landini sent a letter (the "Letter") to Jiwen Zhang, the Chairman of the Board of Directors (the "Board") of Power Solutions International, Inc. (the "Company"), informing Mr. Zhang of Mr. Landini's resignation from the Board effective July 23, 2025. Mr. Landini was also a member of the Audit Committee of the Board. A copy of the Letter is filed herewith as Exhibit 17.1.

The Board had declined to nominate Mr. Landini for re-election at the 2025 annual meeting of stockholders held on July 24, 2025 (the "2025 Annual Meeting"), and accordingly his service as a director had been scheduled to end at the 2025 Annual Meeting irrespective of his resignation.

Mr. Landini alleges in the Letter that (i) he was not re-nominated due to his insistence on complying with his fiduciary duties, and (ii) a majority of the Board showed a lack of concern with respect to exchange listing obligations and management compensation levels, which could be detrimental to the Company.

The Board has reviewed the Letter and disagrees with the allegations made by Mr. Landini in the Letter.

Mr. Landini has been given an opportunity to review this disclosure, and the Company will file any responses timely received from him as an exhibit to an amendment to this Form 8-K.

(e) On July 24, 2025, the Company amended its 2012 Incentive Compensation Plan (the "Plan Amendment") to extend the expiration date from May 26, 2026 to May 26, 2028.

The foregoing description of the Plan Amendment is qualified in its entirety by reference to such amendment, which is filed herewith as Exhibit 10.1.

#### Item 5.07 Submission of Matters to a Vote of Security Holders.
On July 24, 2025, the Company held its 2025 Annual Meeting. All matters submitted for approval by the Company's stockholders, as described in the Company's definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission on June 13, 2025, were approved. The number of shares of common stock entitled to vote at the Company's 2025 Annual Meeting was 23,008,511 representing the number of shares outstanding as of May 30, 2025, the record date for the annual meeting. The voting details follow below.

#### Proposal No. 1: Election of Directors
The following nominees were elected to the Board for a one-year term expiring at the Company's 2026 Annual Meeting, as follows:

## Exhibit 17.1

**Exhibit 17.1** 

July 23, 2025

**Resignation of Kenneth W. Landini as a Director of Power Solutions International, Inc.** 

To the Chairman of the Board of Directors of Power Solutions International, Inc., Mr. James Zhang,

Be advised that I resign from the board of directors of Power Solutions International, Inc. effective July 23, 2025 at 9:00am Central Daylight Time.

Although the board has decided not to nominate me for re-election to the board, despite having the highest vote total last year by a wide margin, I understand the reasons for the apparent, retaliatory nature of the five Chinese directors. My insistence on complying with the board's fiduciary duties, including that of loyalty, by notifying the board in writing of its obligations to, among others, relist on NASDAQ and protect PSI's supply chain by overseeing management's assessment of risk were clearly contrary to the dangerous, slow walking modus operandi of the majority of the directors.

**Further and foremost,** the lack of concern by the same five board members for adequately compensating management could be extraordinarily detrimental to the company and borders on the unconscionable. PSI's common stock has risen approximately 4,500% over the last thirty months or so, yet management has not been rewarded for its efforts with meaningful equity awards. Multiple inquiries for management equity participation of the chairman of the board and the chairman of the compensation committee by investors and me, have been met with preposterous timeline extensions. The long-term incentive plan is supposed to reward employees over a period of time, not to be a long-term project for the compensation committee. Based on past practice, it appears that the board does not plan on rewarding management with equity participation and understand the importance of retaining its highly successful management team.
