“Orion is on a path of profitable growth, increasing profitability and continued market expansion in FY’27,” said Orion’s Chief Executive Officer, Sally Washlow. “Today’s results for Q1’27 — our seventh straight quarter of positive adjusted EBITDA — demonstrate that we are advancing on that path.”

Ms. Washlow pointed to growth drivers ranging from Orion’s expanding business within large customers to a multimillion-dollar entry into the burgeoning hyper-scale data center market to an array of new Orion offerings introduced to the marketplace in recent months.

“Product and service introductions show continued traction, ranging from LED Lighting for hyper-scale data centers to Battery Storage and Electrical Contracting,” said Ms. Washlow. “We have similarly high aspirations for our newly introduced LED Roadway product designed for public roads.”

Ms. Washlow also cited Orion’s strengthening capabilities, such as a newly installed ERP system designed to scale with the Company’s expected growth.

Q1’27 Business Highlights: Commentary from CEO Sally Washlow

Orion’s first-quarter results and full-year expectations continue to illustrate a strong sales funnel, expansion of wallet share within large customers, continuous strengthening of a truly unrivaled proprietary supply chain and continued cost management.

Orion’s first quarter illustrated noteworthy indicators of YOY growth:

— Orion entered the hyper-scale data center market with an LED lighting solution specifically designed for this massive market in Q1’27. Quickly following the product announcement, the Company was awarded a multimillion-dollar customer engagement with one of the world's largest hyper-scale data centers. Orion designed the MPHL2 to be a tailor-made LED Lighting solution for thousands of data centers to be built over the coming years. Meanwhile, the ability to provide unrivaled reliability, flexibility and scalability enables Orion to be a trusted supplier to the current data-center building boom. These unique attributes are of particular importance to Orion’s inaugural data-center customer.

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).

Orion Announces Preliminary FY26 Revenue of $86M and Approximately $2M Adjusted EBITDA;

Reiterates Expectations for Increased Growth and Profitability in FY 2027

Company to Host Q4 and Full Fiscal Year 2026 Investor Call Thursday, June 4, at 10 a.m. ET

Manitowoc, WI – May 19, 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 announced preliminary unaudited expectations for Fiscal Year 2026 of $86 million in revenue and adjusted EBITDA of at least $2 million.

The Company also reiterated expectations for Fiscal Year 2027, which began April 1, of between $95 million and $97 million in revenue and positive adjusted EBITDA.

Orion said that its performance expectations continue to improve because of continuing growth in its backlog, which totaled $30 million on March 31, 2026; and ongoing increases in orders by enterprise customers; successful cost-structure improvements; and Orion’s gains in its marketplace.

“We are demonstrably on a profitable growth path,” said CEO Sally Washlow, who arrived at Orion about 13 months ago. “Our six consecutive quarters of positive adjusted EBITDA are testimony to disciplined cost containment, our robust proprietary supply chain and organic growth from existing and new enterprise customers.”

Ms. Washlow particularly cited expansion of deployments within existing large customers in the automotive, retail and public sectors, whether in deployments of LED lighting, maintenance, electrical Infrastructure or EV charging infrastructure. Orion’s recently awarded project in Battery Energy Storage Systems and Electrical Contracting are also contributing to the Company’s growth, Ms. Washlow said.

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 measure, see the related explanation presented under “Non-GAAP Measures.”

Orion also announced that it will host a conference call and webcast to review its fiscal 2026 full fiscal year and fourth quarter results on Thursday, June 4, 2026, at 10:00 a.m. ET. Orion will release its results prior to the market’s opening that morning.

Non-GAAP Measures

Orion uses adjusted EBITDA, a non-GAAP measure, to supplement the financial measures prepared in accordance with United States (U.S.) generally accepted accounting principles (“GAAP”). Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization, adjusted for stock-based compensation, acquisition related costs, deferred financing costs, restructuring and severance costs, asset impairment and, earnout expenses) is not prepared in accordance with U.S. GAAP. Orion has provided guidance for this non-GAAP measure 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 this non-GAAP measure to evaluate the performance of the business and believes this measurement enables it to make better period-to-period evaluations of the financial performance of core business operations. The non-GAAP measurement is intended only as a supplement to the financial measures prepared in accordance with GAAP, and investors should consider this non-GAAP measurement in
