Orion Announces Major US Retailer’s Additional Commitment for Estimated $10M-15M;

Increases FY27 Revenue Outlook to $100M - $102M

Manitowoc, WI – September 15, 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 that a longtime customer has made a follow-on commitment to the Company for a new LED lighting project estimated to represent revenue of $10 million to $15 million. The new project is at additional locations operated by this retailer.

This latest commitment involves retrofitting interior LED Lighting and IoT system installations at selected locations not previously retrofitted by Orion. Orion maintains that this most recent expansion of work demonstrates the confidence that Orion has earned with this leading retailer over the course of numerous projects spanning several years.

The customer’s latest commitment is expected to be fulfilled on the basis of individual purchase orders, the timing of which is not certain at this time. However, Orion expects to recognize a significant majority of the revenue from this project in the second half of the current Fiscal Year 2027, which ends March 31, 2027.

As a result of today’s announcement, Orion also announced that it expects to achieve total revenue of $100 million to $102 million for FY 2027, representing an increase from its previous outlook of $95 million to $97 million. As previously announced, Orion expects FY’Q2 revenues to decrease compared to the recently announced FY’Q1 revenue of $25.7M. The Company continues to expect to achieve positive Adjusted EBITDA for the fiscal year as a whole.

“Orion has once again earned a significant increase in its scope of work on behalf of one of the biggest names in retailing,” said Orion Chief Executive Officer Sally Washlow. “Orion continues to add substantially to its workflow with this Global Fortune 50 company, as we expand our management of LED Lighting, IoT, Maintenance and Electrical Contracting. We are pleased to continue to earn increasing trust, confidence and business from this industry leader.”

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).
