Orion Reports FY 2026 Revenue of $86M and Adjusted EBITDA of $2.2M After Continued Growth in Q4;

Reiterates FY 2027 Expectation of $95M-$97M in Revenue and Positive Adjusted EBITDA

Manitowoc, WI – June 4, 2026 – Orion Energy Systems, Inc. (NASDAQ: OESX) (Orion Lighting), a provider of energy-efficient LED lighting, electric vehicle (EV) charging stations and maintenance services solutions, today reported improved results for its fiscal 2026 fourth quarter (Q4’26) and full fiscal year 2026 (FY’26) ended March 31, 2026.

Orion’s Q4’26 revenue was $25.7M versus $20.9M in Q4’25 — a 23% increase — while Q4’26 gross margin was up by 950 basis points year-over-year, at 37.0% versus 27.5% in Q4’25. The Company improved its net loss in Q4’26 to $1.5M, compared to a net loss of $2.9M in Q4’25. The Company achieved Q4’26 adjusted EBITDA of $0.8M — marking its sixth consecutive quarter of positive adjusted EBITDA – compared to adjusted EBITDA of $0.2M in Q4’25.

For the full fiscal year of FY’26, Orion’s revenue was $86.3M versus $79.7M in FY’25, while FY’26 gross margin was 32.5% vs. 25.4% in FY’25. The Company improved its net loss in FY’26 to $3.2M, compared to a net loss of $11.8M in FY’25. The Company achieved FY’26 adjusted EBITDA of $2.2M, compared to an adjusted EBITDA loss of $(2.9M) in FY’25.

Each quarter of FY’26 delivered gross margins above 30%, a level of performance not previously seen. This is a result of Orion’s structural reset, which it expects to be continually beneficial moving forward. Similarly, revenue — which came in at the high end of our FY’26 public guidance range — continues to grow as we enter FY’27.

The Company continues to execute on its plan and build momentum in the current fiscal year. Starting FY’27 with a backlog of $30M — a year-over-year increase of $13M, Orion reiterated its expectations of positive adjusted EBITDA on revenue of between $95 million and $97 million in FY’27, which began April 1, 2026, up 12% over FY’26.

The Company said that its increasing expectations for the current fiscal year were validated by a number of factors. The ongoing improvement in the quality and size of its backlog is a result of continued project demand and growing opportunities within many of the Company’s revenue segments.

“The results we are reporting today — highlighted by our sixth straight quarter of positive adjusted EBITDA — validate an observation I have made previously: Orion is demonstrably on a profitable growth path,” said Orion’s Chief Executive Officer, Sally Washlow, who recently completed her first year as CEO. “Our FY’26 results and FY’27 expectations speak clearly to the success of a continuously improving sales funnel, organic growth from large customers, a resilient and adaptable proprietary supply chain and highly disciplined cost containment. We expect FY’27 to demonstrate that Orion is emerging robustly from a turnaround to a sustainable growth company.”

Orion is providing adjusted EBITDA guidance only on a non-GAAP basis and does not provide a reconciliation of its forward-looking adjusted EBITDA non-GAAP guidance to the most directly comparable GAAP measure due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation, the amounts of which, based on historical experience, could be significant. For additional information regarding Orion’s non-GAAP measures, see the related explanation presented under “Non-GAAP Measures.”

Orion is scheduled to discuss these results in an investor call today at 10:00 a.m. ET (details below).

Commentary from CEO Sally Washlow

“It is extremely gratifying to complete my first year as CEO of Orion. In the space of a year, we have gone from a turnaround to a growth company.

Non-GAAP Measures

In addition to the GAAP results included in this presentation, Orion has also included the non-GAAP measures, EBITDA (earnings before interest, taxes, depreciation and amortization), and Adjusted EBITDA (EBITDA adjusted for stock-based compensation, acquisition related costs, deferred financing costs, restructuring and severance costs, asset impairment and, earnout expenses). The Company has provided these non-GAAP measures to help investors better understand its core operating performance, enhance comparisons of core operating performance from period to period, and allow better comparisons of operating performance to its competitors. Among other things, management uses these non-GAAP measures to evaluate the performance of the business and believes these measurements enable it to make better period-to-period evaluations of the financial performance of core business operations. The non-GAAP measurements are intended only as a supplement to the comparable GAAP measurements and Orion compensates for the limitations inherent in the use of non-GAAP measurements by using GAAP measures in conjunction with the non-GAAP measurements. As a result, investors should consider these non-GAAP measurements in addition to, and not in substitution for or as superior to, measurements of financial performance prepared in accordance with generally accepted accounting principles.

Consistent with Regulation G under the U.S. federal securities laws, the non-GAAP measures in this press release have been reconciled to the nearest GAAP measures, and this reconciliation is located under the heading “Unaudited EBITDA Reconciliation” following the Unaudited Condensed Consolidated Statements of Cash Flows included in this press release.

Safe Harbor Statement

Similarly, statements that describe our future outlook, plans, expectations, objectives or goals are also forward-looking statements. Such forward-looking statements are subject to certain risks and uncertainties that could cause results to differ materially from those expected, including, but not limited to, the following: (i) our ability to achieve our budgeted fiscal 2027 revenue expectations, and related public fiscal 2027 revenue guidance, will have a significant impact on our cash flow and stock price and ability to fund our operations and satisfy our debt obligations; (ii) we are currently implementing a new ERP system, which will involve substantial cost and potential disruption to our normal operations; our inability to successfully manage the implementation of our new ERP system could adversely affect our ability to operate our business and otherwise negatively affect our financial reporting and the effectiveness of our internal control over financial reporting; (iii) government tariffs and other actions have adversely affected, and may continue to adversely affect, our business, resulting in increased costs and reduced gross margins; (iv) the reduction or elimination of incentives from the United States government for investments in electric vehicle (“EV”) charging infrastructure may reduce demand for public EV charging products, in addition to reducing overall demand for EVs; (v) we do not have major sources of recurring revenue, a substantial portion of our revenues is derived from major project-based retrofit work that is awarded through a competitive bid process and we depend upon a limited number of customers in any given period to generate a substantial portion of our revenue, and it is generally difficult to predict the timing of projects that will be awarded, which can impact our ability to achieve our expected financial results; (vi) the reduction of revenue from our most significant customer over the past several fiscal years has had, and the potential future loss of other significant customers or a major customer would likely have, a materially adverse effect on our results of operations, financial condition and cash flows; (xiii) the reduction or elimination of investments in, or incentives to adopt, light emitting diode (“LED”) lighting or the elimination of, or changes in, policies, incentives or rebates in certain states or countries that encourage the use of LEDs over some traditional lighting technologies, including due to federal funding restrictions in the United States, could cause the demand for our lighting products to slow; (vii) we are experiencing ongoing increasing pressures to reduce the average selling price of our products and related negative impact on our gross margins, driven largely by the ongoing increase in competition from foreign competitors; (viii) our products use components and raw materials that may be subject to price fluctuations, shortages or interruptions of supply, particularly resulting from tariffs and other trade restrictions; (ix) we increasingly rely on third-party manufacturers for the manufacture and development of our products and product components; (x) we are subject to the risk of a cybersecurity breach; (xi) macroeconomic pressures in the markets in which we operate may adversely affect our financial results; (xii) adverse conditions in the global economy, including due to changes in diplomatic and trade relationships, have negatively impacted, and could in the future negatively impact, our customers, suppliers and business; (xiii) the success of our LED lighting retrofit solutions depends, in part, on our ability to claim market share away from our competitors; and (xiv) the other risks described in our filings with the Securities and Exchange Commission. Shareholders, potential investors and other readers are urged to consider these factors carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on such forward-looking statements. The forward-looking statements made herein are made only as of the date of this press release and we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
