Power Solutions International Files10-K for 2017 and Provides Preliminary Financial Results for 2018

201710-K Includes Audited Results for 2016 and 2017 and Restated Results for 2014 and 2015

Company Expects 2018 Financial Statements to be Filed by the End of the Third Quarter of 2019

WOOD DALE, Ill., May 16, 2019 — Power Solutions International, Inc. (“the Company”) (OTC Pink: PSIX), a leader in the design, engineering and manufacture of emissions-certified, alternative-fuel power systems, announced that it has filed its Annual Report on Form10-K for the year ended December 31, 2017 with the U.S. Securities and Exchange Commission (“SEC”). The filing includes audited financial statements for the fiscal years ended December 31, 2016 and December 31, 2017, as well as quarterly financial results for quarters within those years, and restated financial statements for the fiscal years ended December 31, 2014 and December 31, 2015, and the quarter ended March 31, 2016.

In August 2016, the Company disclosed an internal review of certain accounting matters. Since that time, management and the Audit Committee of the Board, along with the assistance of outside advisors, have been working diligently to identify and undertake meaningful changes to remedy deficient operational and accounting controls and are working to become current with the Company’s financial reporting requirements. The filing of the 2017 Form10-K is a significant step forward in that process.

Anticipated Timing for 2018 and 2019 Filings

The Company plans to file its Quarterly Reports on Form10-Q for the quarters ended March 31, June 30 and September 30, 2018, and its Form10-K for the period ended December 31, 2018, by the end of the third quarter of 2019. In addition to these filings, the Company is working to become current with its 2019 filings. When the Company is current with all of its filings, it will seek to relist its common stock on a national exchange and expects to host an investor conference call to discuss its results and outlook.

Preliminary Unaudited Financial Results for 2018

The Company’s sales for the full year 2018 are estimated to be approximately $500 million, an increase of approximately 20 percent compared to 2017. An associated improvement in gross profit and gross margin is also anticipated; however, the positive impact of the increased gross profit on operating income is anticipated to be more than offset by significant increases in operating expenses, largely the result of increased selling, general and administrative expenses principally due to higher restatement related costs, and higher research, development and engineering expenses for product development activities in support of the Company’s long-term growth objectives. The aforementioned financial data is preliminary and is subject to potential changes as a result of the finalization of the audit.

At the end of 2018, the Company’s total debt was approximately $110 million, which compares to approximately $107 million as of September 30, 2018.    

Management Comments

John Miller, chief executive officer, commented, “With the filing of the restatement and our financial results through 2017, the focus of our finance and accounting team shifts towards the completion of our remaining outstanding filings and becoming current with our filing requirements for 2019. At that time, we plan to seek a listing of our common stock on a national exchange. We have made numerous improvements across the organization to enhance and improve our internal controls over the past several years and are confident we have the right team and processes in place to complete the work necessary to become current. Additionally, over the next few months, in concert with Weichai, our strategic investor and collaboration partner, we will be exploring opportunities to refinance our debt.”

Miller added, “We appreciate the patience and support that we’ve received from our employees, customers, shareholders, lenders and other stakeholders during a challenging period for the Company. While the restatement process and related costs significantly impacted profitability, our business experienced positive momentum in 2017 and 2018. We recognize that a lot of work remains in order to return our business to appropriate levels of profitability but we are confident we are on the right path.”

“We have initiated a comprehensive set of business objectives aimed at improving our profitability, streamlining processes, and strengthening our business, while simultaneously focusing on achieving growth in higher return product lines. We are conducting a thorough review of our customer and product portfolio which has already resulted in strategic price increases in certain areas of our business, along with product redesign and there-sourcing of certain components, to support improved margins. This program is a multi-year effort, and will entail a strategic assessment of certain areas where profitability does not meet our established thresholds. We have also initiated programs to improve both our manufacturing and working capital efficiency.”

“In addition to driving improved margins through pricing and business mix, we are focused on streamlining our business through the implementation of a program to review and identify cost reductions throughout the organization. At the same time, we are working to optimize our business systems and technology to support the remediation of internal controls, improve our

processes, drive greater operational efficiencies and provide us with better and timelier decision making across the organization. These improvements, which entail the reimplementation of our ERP system, will be critical as we strive to grow our business in the future.”

“Lastly, our plan focuses on growing the business in those areas where we can drive the highest return on investment. Accordingly, we have invested heavily in the recruitment of key management, sales and operations staff to support the development and sales of higher margin, heavy-duty engines that serve the energy and industrial markets. Our highly accomplished team is intent on expanding our range of customers, particularly in the datacenter, healthcare and demand response markets, while growing business with existing PSI customers through the marketing of the Company’s expanding product portfolio and the utilization of our customized engineering capabilities. Notably, since the inception of our relationship with Weichai, we’ve obtained EPA approval for 32L and 40L gas models and have development and launch plans for a 53L gas model, as well as diesels in the future. Through the addition of these and other engines, we believe that the addressable market for our products in the power generation space expands to $3 to $4 billion dollars by 2023, compared to less than $1 billion in 2018.”

Miller concluded, “As we look to the future, we believe that we are well-positioned to deliver long-term shareholder value through the execution of our business objectives and our ability to capitalize on the numerous favorable market trends, such as the shift from diesel to alternatives. Through the adoption of our strategy, we believe that we can create a more sustainable and profitable organization.”
