STANDEX REPORTS FISCAL THIRD QUARTER 2026 FINANCIAL RESULTS

SALEM, NH – April 30, 2026 – Standex International Corporation (NYSE: SXI) today reported financial results for the third quarter of fiscal year 2026 ended March 31, 2026.

Commenting on the quarter’s results, President and Chief Executive Officer David Dunbar said, “We delivered another quarter with year-on-year organic growth and strong operating performance. Our sales increased 8.1% year-on-year to $224.6 million driven by 8% contribution from new products and more than 30% contribution from sales into fast growth markets. We realized 6.5% organic growth with a book to bill of 1.05. Our Electronics segment grew 6.8% organically with a book to bill of 1.14. We are well positioned to deliver mid-to-high single-digit organic growth again in the fiscal fourth quarter, primarily driven by new product launches, and strong tailwinds in the electrical grid, space, defense and aviation end markets. Sales from fast growth markets totaled approximately $69 million in the fiscal third quarter and are expected to reach approximately $270 million for the full fiscal year 2026.

Adjusted operating margin expanded by 30 basis points year-on-year to 19.7%. We paid down approximately $62 million of debt in the fiscal third quarter, and our net leverage ratio was reduced to 1.9x.

On March 6th, we completed the divestiture of Federal Industries at an enterprise value of approximately $70 million. The divestiture supports continued portfolio simplification and enables us to focus on larger businesses and fast growth end market opportunities. As such, we will now report under the four operating segments of Electronics, Aerospace & Defense (formerly Engineering Technologies), Scientific, and Engraving & Hydraulics.”

Fiscal Fourth Quarter 2026 Outlook

In fiscal fourth quarter 2026, on a year-on-year basis, the Company expects slightly to moderately higher revenue, driven by mid-to-high single digit organic growth from higher sales into fast growth end markets and increased new product sales, partially offset by the impact on revenue from the recently completed divestiture of Federal Industries. The Company expects slightly lower adjusted operating margin as contributions from organic growth and realization of productivity actions are more than offset by growth investments, higher medical costs, and increased variable compensation expenses.

On a sequential basis, the Company expects slightly higher revenue, driven by increased contributions from fast growth end markets and new product sales, and slightly to moderately higher adjusted operating margin due to higher volume and pricing and productivity initiatives, partially offset by growth investments.

Fiscal Year 2026 Outlook

The Company’s prior fiscal year 2026 sales outlook included a full year contribution from Federal Industries. Considering the divestiture of Federal Industries and barring any unforeseen economic, global trade, or tariffs related disruptions, the Company now expects revenue to grow by approximately $100 million in fiscal year 2026, which will continue to be driven by mid-to-high single digit organic growth in Electronics and double-digit organic growth in Aerospace & Defense. The Company remains on course to release over fifteen new products that it expects will contribute approximately 300 bps of incremental growth. Sales from fast growth markets are on track to grow approximately 45% year-on-year and reach approximately $270 million.

Third Quarter Segment Operating Performance

The Engineering Technologies segment has been re-named as the Aerospace & Defense segment. The Company believes this name change will improve understanding of the business and its end markets. The Hydraulics business has been combined with the Engraving business under Engraving & Hydraulics segment. As a result, the Company will now report under the four operating segments of Electronics, Aerospace & Defense, Scientific, and Engraving & Hydraulics.

Electronics (53% of sales; 66% of segment adjusted operating income)

Revenue increased approximately $8.4 million or 7.6% year-on-year, reflecting organic growth of 6.8% and a foreign currency benefit of 0.8%. Organic growth was driven by sales into fast growth markets and increased new product sales. Adjusted operating income increased approximately $1.9 million or 5.9% year-on-year due to higher volume, pricing initiatives, and product mix, partially offset by growth investments.

The segment had a book-to-bill ratio of approximately 1.14 in the fiscal third quarter, with orders of approximately $136 million.

In fiscal fourth quarter 2026, on a sequential basis, the Company expects slightly to moderately higher revenue, reflecting higher sales into fast growth end markets and increased new product sales. The Company expects slightly higher adjusted operating margin due to higher revenue, partially offset by continued growth investments.

Aerospace & Defense (16% of sales; 12% of segment adjusted operating income)

Revenue increased approximately $9.2 million or 33.7% year-on-year reflecting organic growth of 20.8%, a 12.2% benefit from the McStarlite acquisition, and a foreign currency benefit of 0.7%. Organic growth was primarily driven by increased projects activity in the commercialization of space end market. Adjusted operating income increased approximately $1.5 million or 29.4% year-on-year reflecting higher volume.

In fiscal fourth quarter 2026, on a sequential basis, the Company expects slightly to moderately higher revenue due to growth in new product sales and more favorable project timing, and slightly to moderately higher adjusted operating margin due to higher volume and realization of productivity initiatives.

Scientific (8% of sales; 7% of segment adjusted operating income)

Revenue decreased approximately $0.3 million or 1.7% year-on-year reflecting an organic decline of 1.7% from lower demand at academic and research institutions that were impacted by NIH funding cuts. Adjusted operating income decreased approximately $0.2 million or 4.8% year-on-year due to lower sales.

In fiscal fourth quarter 2026, on a sequential basis, the Company expects slightly higher revenue and similar adjusted operating margin due to product mix.

Engraving & Hydraulics (20% of sales; 12% of segment adjusted operating income)

Revenue increased approximately $1.0 million or 2.2% year-on-year reflecting a foreign currency benefit of 4.0%, partially offset by an organic decline of 1.8%. The organic decline was primarily driven by general market weakness for hydraulics cylinders. Engraving services had organic growth of 4.0%, driven by slightly improved demand in North America and Asia. Adjusted operating income increased approximately $1.1 million or 20.1% year-on-year due to higher sales and the realization of previously executed restructuring actions.

In fiscal fourth quarter 2026, on a sequential basis, the Company expects slightly lower revenue and similar to slightly higher adjusted operating margin from realization of productivity initiatives.

Use of Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with generally accepted accounting principles (“GAAP”), the Company uses certain non-GAAP financial measures, including non-GAAP adjusted income from operations, non-GAAP adjusted net income from continuing operations, free operating cash flow, EBITDA (earnings before interest, taxes, depreciation and amortization) adjusted EBITDA, adjusted EBITDA to net debt, and adjusted earnings per share. The attached financial tables reconcile non-GAAP measures used in this press release to the most directly comparable GAAP measures. The Company believes that the use of non-GAAP measures which exclude the impact of restructuring charges, purchase accounting, amortization from acquired intangible assets, insurance recoveries, discrete tax events, gain or loss on sale of a business unit, acquisition costs, and litigation costs help investors to obtain a better understanding of our operating results and prospects, consistent with how management measures and forecasts the Company's performance, especially when comparing such results to previous periods. An understanding of the impact in a particular quarter of specific restructuring costs, acquisition expenses, or other gains and losses, on net income (absolute as well as on a per-share basis), operating income or EBITDA can give management and investors additional insight into core financial performance, especially when compared to quarters in which such items had a greater or lesser effect, or no effect. Non-GAAP measures should be considered in addition to, and not as a replacement for, the corresponding GAAP measures, and may not be comparable to similarly titled measures reported by other companies.
