EXPLANATORY NOTE

This Amendment No. 1 (this “Amendment”) on Form 10-K/A amends the Annual Report on Form 10-K for the year ended December 31, 2019 of Power Solutions International, Inc. (“PSI” or the “Company”) filed with the Securities and Exchange Commission (the “SEC”) on May 4, 2020 (the “Original 10-K”) to include the information required by Items 10 through 14 of Part III (the “Part III Disclosure”) of the Original 10-K. This information was previously omitted from the Original 10-K in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference to the Company’s definitive proxy statement if such statement is filed no later than 120 days after the Company’s fiscal year-end.

As previously disclosed in the Company’s Form 8-K filed with the SEC on April 29, 2020, the filing of this Amendment on Form 10-K/A was delayed due to circumstances related to the novel coronavirus (“COVID-19”) and its impact on the Company’s operations. The disruptions in transportation, staffing, and technology systems to both the Company and the Company’s professional advisors resulted in limited support from the Company’s staff and professional advisors due to the COVID-19 outbreak. In particular, COVID-19 has caused disruptions in the Company’s day-to-day activities and impaired the Company’s ability to perform necessary work on this Amendment and to file this Amendment by its April 29, 2020 due date. The Company relied on the SEC’s Order Under Section 36 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) Modifying Exemptions From the Reporting and Proxy Delivery Requirements for Public Companies, dated March 4, 2020 and amended March 25, 2020 (Release Nos. 34-88318 and 34-88465) (collectively the “Order”), to delay the filing of this Amendment. The Company is relying on the Order in filing this Amendment.

The information included herein as required by the Part III Disclosure is more limited than what is required to be included in the definitive proxy statement to be filed in connection with PSI’s 2020 Annual Meeting of Stockholders. Accordingly, the definitive proxy statement to be filed at a later date will include additional information related to the topics herein and additional information not required by the Part III Disclosure.

Pursuant to the SEC rules, Part IV, Item 15 has also been amended to contain the currently dated certificates from the Company’s principal executive and financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. The certificates of the Company’s principal executive and financial officer are attached to this Amendment as Exhibits 31.3 and 31.4. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Additionally, PSI is not including the certificate under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment.

Except for the information described above, the Company has not modified or updated disclosures provided in the Original 10-K in this Amendment. Accordingly, this Amendment does not reflect events occurring after the filing of the Original 10-K or modify or update those disclosures affected by subsequent events. Information not affected by this Amendment is unchanged and reflects the disclosures made at the time the Original 10-K was filed.

Employment Agreements with Named Executive Officers

The Company has entered into employment agreements with each of PSI’s named executive officers, except for Mr. Lin who is party only to an offer letter. Each arrangement specifies the annual base salary for the executive, which may be increased at the discretion of the Board. In addition, the arrangements specify that the executives may be eligible to receive an annual incentive bonus under the Company KPI plan and awards under the Company’s long-term incentive plan. Under the terms of the arrangements, each named executive officer is also eligible to participate in the same benefit programs, as may be in effect from time to time, for other senior management employees of the Company generally. None of the arrangements with the Company’s named executive officers contain any change in control payments or benefits.

If the Company terminates Mr. Miller without cause (as defined in his employment agreement), Mr. Miller would be eligible for: (i) certain accrued obligations; (ii) any determined, but unpaid KPI bonus relating to the fiscal year prior to the fiscal year of termination; (iii) 12 months of severance; and (iv) 12 months of health benefit continuation coverage on the same terms as was provided before Mr. Miller’s termination.

Mr. Miller needed to remain employed in good standing on each of the foregoing payment or vesting dates in order to receive a payout of cash or shares, as applicable.

If Mr. Avery’s employment terminates with the Company, he will generally receive the same payments and benefits as Mr. Miller. In addition, if the Company terminates Mr. Avery without cause (as defined in his employment agreement), Mr. Avery resigns, or his employment is terminated by death or disability, he will receive a prorated KPI bonus through his termination date for the fiscal year in which his termination occurs once the KPI bonus has been determined by the Board.

Mr. Winemaster’s employment agreement describes his participation in the KERP, under which, in July 2017, he was granted a retention bonus opportunity totaling $87,200 payable in five installments, with the first four installments of $10,900 paid on each of July 31, 2017, September 30, 2017, December 31, 2017 and March 30, 2018 and the fifth installment of $43,600 being paid on March 30, 2019. In addition, in November 2017, Mr. Winemaster received 45,223 shares of restricted stock under the 2012 Plan, with 22,611 shares vesting on March 31, 2018 and the remaining 22,612 shares vesting on March 31, 2019. Mr. Winemaster needed to remain employed in good standing on each of the foregoing payment or vesting dates in order to receive a payout of cash or shares, as applicable.

If the Company terminates Mr. Winemaster without cause (as defined in his employment agreement) or for any reason other than for cause, or if Mr. Winemaster’s employment is terminated due to his death or disability, he will generally receive the same payments and benefits as Mr. Miller receives upon a termination without cause by the Company. Upon such termination scenarios, Mr. Winemaster also would have received accelerated payment or vesting, as applicable, for his cash and equity awards under the KERP. If Mr. Winemaster is terminated for cause, he will only receive accrued obligations required to be paid by applicable law.

Messrs. Miller, Avery and Winemaster are bound by certain confidentiality and restrictive covenants under their employment agreements.

11

Mr. Lin was granted a sign-on award of 30,000 shares of restricted stock under the 2012 Plan, with 15,000 shares vesting on July 25, 2020 and 15,000 shares vesting on July 25, 2021, subject to Mr. Lin’s continued employment with the Company on each vesting date. If Mr. Lin’s employment terminates for any reason, he will only receive accrued obligations required to be paid by applicable law.

Outstanding Equity Awards at 2019 Year-End

The table below shows outstanding equity awards as of December 31, 2019 held by each named executive officer.

Potential Payments Upon Termination or Change in Control

As of December 31, 2019, the Company had employment agreements with each of the named executive officers, which provided for payments upon termination without “cause” (as summarized above under the heading, “Employment Agreements with Named Executive Officers”).

Other than these arrangements and accelerated vesting of equity awards under the 2012 Plan, the Company currently does not have any compensatory plans or arrangements that provide for any payments or benefits upon the resignation, retirement or any other termination of any of the named executive officers, as the result of a change in control, or from a change in any named executive officer’s responsibilities following a change in control.

12

Clawback Policy

As part of the Company’s derivative litigation settlement, the Company adopted a formal clawback policy covering specified incentive compensation of officers (defined as only those individuals the Company has designated as subject to the reporting and liability provisions of Section 16 of the Exchange Act). This provision will be included in any new or amended employment agreements entered into with any existing or future officers of the Company on or after April 11, 2019. The clawback provision will provide that upon a termination for cause, an officer shall automatically forfeit:

“Cause” means that the Company makes a good faith determination that the officer has: (1) violated any Company policy or procedure that causes material harm or risk to the Company including, but not limited to, sexual harassment, misappropriation, or fraud; (2) been convicted of a crime which is injurious to the Company’s operation or reputation; (3) engaged in a material breach of the officer’s employment agreement; (4) engaged in willful failure or willful inability to perform the Officer’s duties under the officer’s employment agreement; (5) engaged in any act or omission, which in any material way impairs the reputation, goodwill or business position of the Company; or (6) the officer is prohibited by order of a government agency or court from being employed by the Company or any Company affiliate in the role set forth in the officer’s employment agreement.

For purposes of subsections (3) and (4) of this definition, a termination will not be for “Cause” to the extent such conduct is curable, unless the Company shall have notified the officer in writing describing such conduct and prescribing conduct required to cure such conduct and the officer shall have failed to cure such conduct within thirty (30) business days after his or her receipt of such written notice. For purposes of this definition of Cause, no act or failure to act on the part of the officer shall be considered willful if it is done, or omitted to be done, by the officer in good faith and with a good-faith belief that the officer’s act or omission was in the best interests of the Company.

SECURITY OWNERSHIP OF

CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information known to the Company regarding beneficial ownership of shares of the Company’s common stock as of June 1, 2020, by:

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition

14

of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Beneficial ownership of the Company’s common stock is based on 22,913,644 shares of the Company’s common stock issued and outstanding as of June 1, 2020.

Except as otherwise indicated in the footnotes, each of the beneficial owners listed has, to the Company’s knowledge, sole voting and investment power with respect to the indicated shares of common stock. Addresses for the beneficial owners are set forth in the footnotes to the table.

RELATED PERSON POLICY AND TRANSACTIONS

Related Person Transactions Policy and Procedures

In the ordinary course of the Company’s business, the Company may from time to time enter into transactions with its directors, officers and 5% or greater stockholders. The Audit Committee is responsible for approving related party transactions, as defined in applicable rules promulgated by the SEC. Our Audit Committee operates under a written charter pursuant to which all related party transactions are reviewed for potential conflicts of interest situations. Such transactions must be approved by our Audit Committee prior to consummation.

Related Person Transactions

Other than as described below, during 2019 and 2018, the Company did not enter into any related person transactions.

Weichai

In March 2017, the Company and Weichai executed a share purchase agreement (the “SPA”) with Weichai. Under the terms of the SPA, Weichai invested $60.0 million in the Company (the “Weichai Transaction”) by purchasing a combination of newly issued common and preferred stock as well as a stock purchase warrant, which significantly strengthened the Company’s financial condition and contributed to the subsequent extinguishment of a $60.0 million term loan.

The stock purchase warrant issued to Weichai (the “Weichai Warrant”) was exercisable for any number of additional shares of common stock such that Weichai, upon exercise, would hold 51% of the common stock then outstanding on a fully dilutive basis, on terms and subject to adjustments as provided in the SPA. On April 23, 2019, Weichai exercised the Weichai Warrant and increased its ownership to 51.5% of the Company’s outstanding common stock, as of such date. With the exercise of the Weichai Warrant in April 2019, Weichai owns a majority of the outstanding shares of the common stock of the Company. As a result, Weichai is able to exercise control over matters requiring stockholders’ approval, including the election of the directors, amendment of the Company’s charter and approval of significant corporate transactions.

16

Weichai also entered into an Investor Rights Agreement (the “Rights Agreement”) with the Company upon execution of the SPA. The Rights Agreement provides Weichai with representation on the Company’s Board and management representation rights. Weichai currently has three representatives on the Board. According to the Rights Agreement, once Weichai exercised the Weichai Warrant and became the majority owner of the Company’s outstanding shares of common stock calculated on a fully diluted as-converted basis (excluding certain excepted issuances), the Company became required to appoint to the Board an additional individual designated by Weichai or such additional numbers of individuals so that Weichai designees constitute the majority of the directors serving on the Board. As of the date of this filing, Weichai has not designated an additional representative to the Board.

Industrial Electronic Controls

The Company purchased $0.4 million of products in 2018 from Industrial Electronic Controls, a supplier of custom throttles, sensors, and custom electronics. Gary S. Winemaster, former Chairman of the Board, Chief Executive Officer and President and non-executive Chief Strategy Officer divested his 50% of Industrial Electronic Controls during 2018.

Retirement Agreement

On April 29, 2019, the Company entered into a retirement agreement with Gary Winemaster, the Company’s then Chief Strategy Officer, pursuant to which he retired on May 3, 2019 and the Company agreed to pay $600,000 in installments through February 28, 2020. The agreement provides for a mutual release. Mr. Winemaster agreed to cooperate with the Company as needed and to extend his non-compete period to three years.

Director Independence

While the Company’s stock is currently traded on the OTCPink market, which requires the Company to establish and maintain fundamental corporate governance standards, the Company has elected to adopt more exacting governance standards that are substantially similar to the NASDAQ listing governance standards. The Board has determined that the Company is a “controlled company,” as defined in Rule 5615(c)(1) of the NASDAQ Marketplace Rules. The Board has based this determination on the fact that Weichai currently owns a majority of the Company’s common stock. Under the NASDAQ rules, a company where more than 50% of the voting power for the election of directors is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain NASDAQ corporate governance requirements, including:

The Company is not currently relying on the controlled company exemption for the above requirements, but may in the future.

Unless the Company avails itself of the “controlled company” status as discussed above, pursuant to NASDAQ listing standards, a majority of the members of the Board must qualify as “independent,” as affirmatively determined by the Board. In addition to the NASDAQ independence requirements, the Company also applies the independence guidelines set forth in its Corporate Governance Guidelines, which are available on the Company’s website at www.psiengines.com in the “Investors” section, under “Governance” which are substantially similar to the NASDAQ’s director independence requirements and “controlled company” exemptions. Consistent with this requirement, based on the review and recommendation of the Company’s Nominating Committee, the Board reviewed all relevant identified transactions or relationships between each of the Company’s directors, or any of their family members, and PSI, the Company’s senior management and the Company’s independent registered public accounting firm, and has affirmatively determined that each of Dr. Sun, Messrs. He, Jiang, Landini, Simpkins and Wu and Ms. Coolidge meets the standards of independence under the applicable NASDAQ listing standards. In making this determination, the Board found Dr. Sun, Messrs. He, Jiang, Landini, Simpkins and Wu and Ms. Coolidge to be free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company. The Board has also determined that each member of its Audit Committee is independent under NASDAQ Rule 5605(a)(2).
