LSI INDUSTRIES REPORTS FISCAL 2026 FOURTH QUARTER AND FULL-YEAR RESULTS

AND DECLARES QUARTERLY CASH DIVIDEND

CINCINNATI, August 20, 2026 – LSI Industries Inc. (Nasdaq: LYTS, “LSI” or the “Company”) a leading U.S. based manufacturer of commercial lighting and display solutions, today reported financial results for its fiscal 2026 fourth quarter and full year ended June 30, 2026.

FISCAL 2026 FOURTH QUARTER RESULTS

FISCAL 2026 FULL YEAR RESULTS

LSI reported net sales of $234.6 million in the fourth quarter, an increase of 51% versus the prior year period, led by sustained growth in key vertical markets and the first full-quarter contributions from the acquisition of Royston Group (“Royston”) on March 24, 2026. Excluding acquisition-related contributions, net sales increased 8% in the fourth quarter when compared to the year-ago period.

LSI reported fourth quarter net income of $6.9 million, or $0.18 per diluted share, including $3.0 million of acquisition-related expenses, while adjusted net income was $14.4 million, or $0.38 per diluted share.

The Company generated adjusted EBITDA of $25.7 million in the fourth quarter, an increase of 50% when compared to $17.1 million in the prior year quarter. Fourth quarter adjusted EBITDA margin rate increased 90 basis points sequentially versus the fiscal third quarter, driven by sustained operational discipline and a favorable margin contribution from the Royston acquisition.

For the twelve-month period ended June 30, 2026, LSI reported net sales of $689.4 million with adjusted earnings per diluted share of $1.25 compared to $1.07 in fiscal 2025. Fiscal 2026 sales include the partial year impact from the strategic acquisition of Royston.

For full-year fiscal 2026, LSI delivered margin expansion across adjusted operating income, adjusted net income, and adjusted EBITDA, driven by volume growth, strategic price actions, and productivity initiatives.

LSI generated Adjusted EBITDA of $69.7 million in fiscal year 2026, an increase of 27% versus the prior year, inclusive of an adjusted EBITDA margin rate of 10.1%, or 50 basis points above fiscal year 2025. A reconciliation of GAAP and non-GAAP financial results is included in this press release.

LSI generated free cash flow of $9.7 and $39.0 million for the fourth quarter and full year fiscal 2026, respectively. As of June 30, 2026, the Company had a ratio of net debt to proforma trailing twelve month adjusted EBITDA of 2.7x, and approximately $95 million of availability under its $350 million senior secured credit facility.

The Company declared a regular cash dividend of $0.05 per share payable on September 8, 2026, to shareholders of record on August 31, 2026.

MANAGEMENT COMMENTARY

“Fiscal 2026 was a transformational year for LSI, one in which we delivered record sales and profitability within our core business, while completing our largest acquisition to-date, with the purchase of Royston Group,” stated James A. Clark, President and CEO of LSI. “Over the past year, we continued to expand our differentiated portfolio of integrated retail branding solutions across a growing roster of leading brands, while reinforcing our market-leading positions in key consumer environments, including refueling, grocery and quick-service restaurants, through a collaborative approach focused on elevating the consumer experience.

“Fiscal fourth quarter net sales increased materially versus the prior-year period, supported by a combination of organic growth and contributions from the Royston acquisition,” stated Clark. “The addition of Royston has taken our vertical market strategy to a new level, creating unprecedented opportunities for commercial synergies that, over time, are expected to further demonstrate the power and durability of our value-compounding business model. To that end, adjusted net income increased nearly 40% versus the prior-year period in the fourth quarter, driven by a combination of volume growth, price discipline, and improved operational efficiency, consistent with our strategic focus.

“Our acquisition of Royston has further strengthened our differentiated value proposition across our vertical markets, creating a one-of-one platform that is generating strong enthusiasm among customers and partners for its ability to elevate the consumer experience and strengthen their brands in the marketplace,” continued Clark. “We are well positioned to capitalize on incremental growth opportunities by expanding our share of business with existing customers while attracting new customers that recognize the many benefits of partnering with our integrated, one-of-one, solutions-based platform.

“Within our Display Solutions segment, net sales doubled from the previous year period, including 18% organic growth, when compared to the fiscal fourth quarter 2025. Display segment adjusted EBITDA margin rate increased to 12.4%, the highest level reached in nearly three years, and an increase of 180 basis points versus the year-ago period,” stated Clark.

“Organic growth in Display Solutions for the fourth quarter was supported by strengthening demand across the grocery and refueling/c-store vertical markets. Within the grocery vertical, refrigerated and non-refrigerated display cases sales increased 21% year-over-year, as grocery customers continued to invest in store décor and an enhanced consumer shopping experience. Activity within this vertical has steadily improved over the past two years following the industry-wide pause related to the proposed merger of two large grocery chains, and we expect demand to remain elevated entering fiscal 2027.

“Across the refueling/c-store vertical, fourth quarter sales increased 16% versus the prior year quarter. Both outdoor print graphics and EMI store interior products produced double-digit growth. Project activity remains healthy across our multi-brand customer base, including both new store and renovation activity. In the quarter, LSI was awarded a multi-year program with a large oil company to renovate approximately 2,500 sites. The program includes renovation of all exterior branding elements and includes both products and services. This represents a new customer win for our business, with the breadth of our integrated One LSI solution set serving as a key differentiator in displacing long-standing incumbent suppliers.

“The integration of Royston continues to advance at an accelerated pace as we refine and deploy a unified customer-facing value proposition and go-to-market model. Royston fourth quarter sales declined modestly on a year-over-year basis, consistent with our expectations, as we narrow our strategic focus around a higher-value product/project mix. Importantly, several of Royston’s largest c-store customers are in the initial phase of a multi-year renovation and new construction cycle, with project activity that is expected to ramp beginning in fiscal 2027 and continue throughout the next several years,” stated Clark.

“Entering fiscal 2027, we anticipate a sustained, elevated pace of project activity within the Display Solutions segment. As has been the case in recent years, we also expect the timing of project activity will not be linear, as customers navigate site scheduling, permitting, and procurement requirements. Given a dynamic operating environment, we will continue to adapt and respond accordingly, while providing our customers with an integrated, on-stop solution that solves for the complexities of large-scale site construction and remodeling project management.

“Within Display Solutions, project activity remains elevated and order rates remain strong, with a book-to-bill of approximately 1.0x on strong sales,” continued Clark. “Importantly, order rates do not include the $30 million refueling/c-store program award we received during the fourth quarter 2026.

“For our Lighting segment, fourth quarter sales increased 17% versus the fiscal third quarter but declined 3% when compared to the fiscal fourth quarter 2025, the result of a soft quarter for the automotive and QSR verticals, where project activity can be uneven throughout the fiscal year.

“For fiscal year 2026, Lighting segment sales increased 7%, with growth driven by increased penetration of national accounts, together with improved demand for outdoor area lighting,” continued Clark. “Our recently launched V-LOCITY family of outdoor area lighting continues to gain market acceptance, with customers recognizing the industry leading specifications and performance afforded by the new product line. In addition, we are in the final development phase of our new Velocity Flood light fixture line, with initial sizes to be launched in the calendar year fourth quarter. The new Flood range expands our high performing Velocity series of products, further strengthening our outdoor range of products. Lighting fourth quarter orders were 5% above last year with a book-to-bill above 1.0.”

Clark concluded, “During fiscal 2026, we built upon a strong foundation for profitable growth as we meaningfully expanded our capabilities, significantly increased our market share in key verticals, and continued to focus on driving a unique-to-market value proposition that has fundamentally redefined the retail branding solution category. With the addition of Royston, we’re focused on realizing the benefits of scale, while leveraging a proven playbook that prioritizes on-plan execution. Our long-standing customer relationships, together with the trust and confidence customers place in the combined LSI and Royston brands, position us to become an even more valuable strategic partner and capture a greater share of wallet, over time. We’re confident in the outlook for our business and look forward to continuing to create value with our customers, employees and shareholders in the years ahead.”

Earnings per share represent diluted earnings per share.

Lighting Segment net sales of $266.2 million increased 7% and Display Solutions Segment net sales of $423.2 million increased 30% from last year’s net sales.

Earnings per share represent diluted earnings per share.

The balance sheet on June 30, 2026, included current assets of $295.9 million, current liabilities of $149.9 million and working capital of $146.0 million, which includes cash of $14.3 million. The current ratio was 2.0 to 1. The balance sheet also included shareholders’ equity of $360.7 million and long-term debt of $245.9 million. It is the Company’s priority to continuously generate sufficient cash flow, coupled with our credit facility, to adequately fund operations.

Cash Dividend Actions

The Board of Directors declared a regular cash dividend of $0.05 per share for the fourth quarter of fiscal 2026, payable September 8, 2026, to shareholders of record as of the close of business on August 31, 2026. The indicated annual cash dividend rate is $0.20 per share. The Board of Directors has adopted a policy regarding dividends which provides that dividends will be determined by the Board of Directors in its discretion based upon its evaluation of earnings both on a GAAP and non-GAAP basis, cash flow requirements, financial condition, debt levels, stock repurchases, future business developments and opportunities, and other factors deemed relevant by the Board.

Non-GAAP Financial Measures

This press release includes adjustments to GAAP operating income, net income, and earnings per share for the three and twelve months ended June 30, 2026, and 2025. Operating income, net income, and earnings per share, which exclude the impact of long-term performance-based compensation expense, the amortization expense of acquired intangible assets, commercial growth opportunity expense, acquisition costs, the lease expense on the step-up basis of acquired leases, and restructuring and severance costs, are non-GAAP financial measures. We further note that while the amortization expense of acquired intangible assets is excluded from the measures, the revenue of the acquired companies is reflected in the measures, and the acquired assets contribute to revenue generation. We exclude these items because we believe they are not representative of the ongoing results of the operations of the business. Also included in this press release are non-GAAP financial measures, including Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA and Adjusted EBITDA), Net Debt to Adjusted EBITDA, Free Cash Flow, and organic sales growth. We believe that these are useful as supplemental measures in assessing the operating performance of our business. These measures are used by our management, including our chief operating decision maker, to evaluate business results, and are frequently referenced by those who follow the Company. These non-GAAP measures may be different from non-GAAP measures used by other companies. In addition, the non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Non-GAAP measures have limitations, in that they do not reflect all amounts associated with our results as determined in accordance with U.S. GAAP. Therefore, these measures should be used only to evaluate our results in conjunction with corresponding GAAP measures. Below is a reconciliation of these non-GAAP measures to net income and earnings per share reported for the periods indicated, along with the calculation of EBITDA, Adjusted EBITDA, Free Cash Flow, Net Debt to Adjusted EBITDA, and organic sales growth.
