LSI Fiscal Q4 2026 Earnings: Royston Drives 51% Sales Growth

LSI Industries (NASDAQ: LYTS) reported fiscal Q4 2026 net sales of $234.6 million for the quarter ended June 30, up 51% from $155.1 million, while diluted GAAP EPS fell to $0.18 from $0.26. The first full-quarter contribution from Royston drove much of the sales increase, although organic growth remained positive at 8% and adjusted earnings improved.

Core Earnings Data

Royston, acquired on March 24, 2026, was the main source of the difference between reported and organic growth. Adjusted net income rose 37% and adjusted EBITDA increased 50%, but GAAP net income declined as acquisition-related costs and higher interest expense weighed on reported earnings.

Reported gross margin was approximately 24.5%, down from 26.1% a year earlier. Adjusted EBITDA margin was nearly unchanged year over year at 10.9%, although it improved 90 basis points from the fiscal third quarter.

For the full fiscal year, net sales increased 20% to a record $689.4 million. Adjusted EPS rose to $1.25 from $1.07, adjusted EBITDA increased 27% to $69.7 million, and free cash flow totaled $39.0 million.

Business and Segment Performance

Display Solutions generated $164.2 million in fourth-quarter sales, double the prior-year amount. Even excluding acquisition contributions, segment sales grew 18%, showing that the improvement was not solely attributable to Royston. Adjusted EBITDA margin reached 12.4%, up 180 basis points and the segment’s highest level in nearly three years.

Demand strengthened in two important Display Solutions verticals. Sales of refrigerated and non-refrigerated grocery display cases rose 21%, while refueling and convenience-store sales increased 16%. LSI also received a multi-year award from a large oil company covering renovations at approximately 2,500 sites. Management said Display Solutions’ book-to-bill ratio was approximately 1.0 on elevated sales and did not include a separate $30 million refueling and convenience-store program award.

Royston’s own fourth-quarter sales declined modestly year over year as LSI narrowed its focus toward higher-value products and projects. Management expects activity among several of Royston’s large convenience-store customers to begin ramping in fiscal 2027, but it also cautioned that project timing may be uneven because of scheduling, permitting, and procurement requirements.

Lighting segment sales were $70.5 million, down 3% year over year but up 17% sequentially. Automotive and quick-service restaurant projects were soft during the quarter. Lighting orders nevertheless increased 5% from a year earlier, and book-to-bill remained above 1.0.

Profitability, Cash Flow, and the Balance Sheet

The quarter’s reported profitability did not increase as quickly as sales. Gross profit rose 42%, below the 51% increase in revenue, while selling and administrative costs climbed to $42.9 million from $28.5 million. Consequently, operating margin declined to approximately 6.2% from 7.7%.

Free cash flow was $9.7 million in the quarter. At June 30, LSI held $14.3 million of cash, had $245.9 million of long-term debt, and reported approximately $95 million of availability under its $350 million secured credit facility. Net debt equaled 2.7 times pro forma trailing-12-month adjusted EBITDA.

The board declared a quarterly cash dividend of $0.05 per share, payable September 8, 2026, to shareholders of record on August 31. The indicated annual dividend rate is $0.20 per share.

Acquisition-Led Scale Lifted Adjusted Profit but Pressured GAAP EPS

The quarter produced a clear divergence between reported sales growth and GAAP earnings. Total sales rose 51%, compared with organic growth of 8%, reflecting Royston’s first full-quarter contribution. Adjusted net income and adjusted EBITDA increased substantially, but GAAP net income declined 16%.

Several items explain that gap. LSI recorded approximately $3.0 million of acquisition costs and $3.8 million of acquired intangible-asset amortization in its operating-income reconciliation. Net interest expense also increased to $4.1 million from $0.9 million following the expansion of the balance sheet. In addition, diluted weighted-average shares rose to 37.7 million from 31.0 million, causing GAAP EPS to fall faster than net income.

Operationally, management attributed the 90-basis-point sequential improvement in adjusted EBITDA margin to operating discipline and Royston’s favorable margin contribution. The next test is whether acquisition synergies and higher-value projects can support margins while acquisition expenses, interest costs, and a larger share count continue to affect GAAP results.

Risks Investors Need to Watch

• Dependence on acquisition contributions: Reported growth of 51% was substantially higher than organic growth of 8%. Royston’s integration and the conversion of cross-selling opportunities are therefore important to sustaining the expanded revenue base.
• Higher leverage and interest expense: Long-term debt reached $245.9 million, net leverage was 2.7 times pro forma adjusted EBITDA, and quarterly net interest expense increased to $4.1 million. These costs can limit the conversion of operating gains into net income.
• Uneven project timing: Management expects elevated Display Solutions activity, but permitting, procurement, and customer scheduling can shift revenue between quarters.
• Segment divergence: Display Solutions posted rapid growth, while Lighting sales declined 3% as automotive and quick-service restaurant activity softened.
• Pressure on reported margins and EPS: Gross and operating margins declined year over year, while acquisition adjustments and the higher diluted share count created a sizable gap between GAAP and adjusted earnings.

Summary

LSI’s fiscal fourth quarter was shaped by Royston’s first full-quarter contribution, which expanded revenue and adjusted profit while Display Solutions also delivered double-digit organic growth. GAAP earnings moved in the opposite direction because of acquisition costs, higher interest expense, margin pressure, and dilution. Fiscal 2027 performance will depend on Royston integration, the timing of large Display Solutions projects, and whether improved operating efficiency can translate the larger revenue base into stronger reported profitability.
