STANDEX INTERNATIONAL CORP/DE/ (SXI) stock intrinsic value fair value estimate & owner earnings analysis

Standex International is a diversified maker of engineered components sold into niche industrial markets. After selling Federal Industries in March 2026 it reports four segments: Electronics (reed switches, sensors, magnetics and, since the November 2024 Amran/Narayan acquisition, low- and medium-voltage instrument transformers for power grids; $475 million of fiscal 2026 sales), Aerospace & Defense (formed-metal aircraft, space and defense components including McStarlite; $135 million), Engraving & Hydraulics (mold texturizing for automotive and consumer tooling plus dump-truck and trailer hydraulic cylinders; $182 million) and Scientific (laboratory and medical refrigeration and cryogenic storage; $76 million). About 58% of sales are booked in the United States and 26% in Asia Pacific, with India now a large contributor. How we measure earnings. We start from cash generated by continuing operations, remove the year-to-year swings in receivables, inventories and payables, subtract stock compensation as a real cost, and subtract the capital spending needed to maintain the business (spending tied to revenue growth is treated as investment). Pension contributions stay in as a cost. Amortization of acquired intangibles (about $17.7 million in fiscal 2026) is added back because it is a sunk acquisition cost; the wearing-out of those acquired customer relationships is instead carried in the cases by holding cash flow flat in dollars, and in the bear case by letting it shrink after year ten. On this basis owner earnings per share ran $2.64 (fiscal 2018), $3.28, $4.24, $4.73, $5.66, $6.10, $5.74 (2024), $4.14 (2025) and $6.90 (2026). Adding back cash interest gives what the business itself produces before its lenders: $6.05 to $6.45 a share in fiscal 2022-2024, $5.90 in 2025 and $9.44 ($114 million) in 2026. The starting level. The fiscal 2025 acquisitions, about $479 million in total and led by Amran/Narayan, were financed with bank debt and transformed the company, and only fiscal 2026 contains a full year of it, so we built the level from its parts rather than from one strong year. The pre-acquisition business produced a median of about $73 million a year before interest in fiscal 2022-2024; removing Federal Industries (about $5 million a year after tax) leaves roughly $67 million. Electronics acquisitions added about $26 million of operating income in their first partial year and Electronics operating income reached $121 million in fiscal 2026 against $64 million in fiscal 2024, which supports roughly $35-40 million a year of cash from the acquisitions; we use $35 million because fiscal 2026 grid demand pushed Electronics margins to 25.5% from 19.9% two years earlier. That gives a through-cycle level of about $102 million ($8.45 a share). Fiscal 2026 itself was flattered by removing $23.8 million of working-capital build, but was held down by $12.2 million of restructuring, $4.1 million of deal costs and cash tax on the $57.1 million Federal gain; fiscal 2025 carried $21.4 million of deal costs. Business cash flow per share rose 60% in fiscal 2026; the base case starts year one at $102 million, below fiscal 2026, so it assumes none of that jump continues. Base case ($104.93 a share). Cash flow holds at $102 million a year in dollars, which means it shrinks after inflation. Price increases to pass through cost inflation and tariffs are a demonstrated habit, but any sales growth would tie up working capital at about 25 cents per dollar of new sales, so we credit none. We also credit nothing for management's fiscal 2027 outlook (mid to high single-digit sales growth, more than 20 new products, fast-growth market sales up about 20%) or for future bolt-on acquisitions, which consume cash at prices close to what they are worth. The level continues beyond year ten because the business has renewed itself for seven decades by refreshing its product lines and portfolio, funded from operating spending already deducted. The business is worth about $1,700 million; it owes $433.5 million net ($518.2 million of bank borrowings plus the $64.0 million paid on July 2, 2026 for the last 9.9% of Narayan, less $148.7 million of cash above an estimated $30 million needed to operate), leaving $1,266 million. Bear case ($56.85 a share). Year one produces $100 million. Then a downturn like 2008-2009, when Standex's sales fell 13% and operating income fell from $38.9 million to $6.0 million in fiscal 2009, cuts cash earnings 40% to $60 million in fiscal 2028 and 2029. Hydraulics (truck builds), Engraving (auto model launches) and Electronics industrial demand are the exposed pieces. The bank facility renewed in February 2023 for five years matures in early 2028, in the middle of that trough; with leverage at 2.41 times against a 3.5 times covenant, a 40% earnings drop would push it toward the limit, so we assume refinancing about three points more expensive on roughly $450 million for three years ($13.5 million a year). The business still covers its interest in the trough. Recovery reaches only $90 million by fiscal 2031 as the grid-equipment boom fades and laboratory demand stays weak from NIH funding cuts, and after year ten cash flow shrinks 3% a year as acquired customer relationships wear out. The business is worth about $1,120 million against $433.5 million owed, leaving $686 million. Bull case ($146.92 a share). The backlog of $318.5 million due within a year and the 14% organic growth in defense work in fiscal 2026 lift cash to $112 million in fiscal 2027 and $118 million in 2028; continued price pass-through and small bolt-on deals funded from cash then add 2% a year after working capital, reaching $138 million by year ten, held flat thereafter. The business is worth about $2,207 million against $433.5 million owed, leaving $1,774 million. Our previous figures were prepared on a different basis and are not comparable. One business fact is now treated explicitly: the $64.0 million Narayan buyout agreed June 26, 2026 is counted as money owed. Margin-of-safety price. We are moderately sure of the earnings level: the legacy businesses have a long record, but about a third of today's cash earnings comes from an acquisition owned for less than two years, in a market (utility grid equipment) that is enjoying unusually strong demand. The worst plausible outcome is a deep industrial recession arriving as the credit facility comes due in 2028, combined with a reversal in grid spending; debt of about 2.4 times EBITDA as the lenders measure it is manageable, no customer accounts for more than 5% of sales, and no regulator or controlling owner stands over the company, so the structure should survive, but shareholders could see dividends cut and costly refinancing. The two things we are most likely to be wrong about are how much of the acquired businesses' fiscal 2026 earnings are a cyclical peak, and whether the steady working-capital build seen over the last decade (about $14 million a year, more than growth alone explains) is a permanent cost. If the acquired earnings fall back a third and $10 million a year of that build is permanent, the business would produce about $80 million and the shares would be worth roughly $75. During the holding period, the business pays a dividend of about $1.34 a share and, at the base level, retains roughly $4.70 a share a year to pay down debt. The margin-of-safety price is $55: from that price, if the base case holds, debt repayment and dividends would carry per-share value to roughly $125-130 within four to five years, which the base case implies is about a 20% yearly return; if the two likely errors above both prove true, that outcome implies about 12% a year over five years; and if the bear case's downturn and expensive 2028 refinancing arrive together, the shares would be worth about $55.
