I track a public mid-cap industrial cohort because the 10-K disclosure granularity exceeds anything available privately, and because the cohort is the implicit reference every $30M–$300M private manufacturer gets benchmarked against in a sponsor diligence room. The Q2 2026 read is the cleanest comparable set I have built since the COVID-era inventory distortions cleared. The five-name anchor cohort — Caterpillar, Deere, Parker-Hannifin, Illinois Tool Works, and Emerson Electric — clears 2.6% capex of revenue on the median, holds gross margin between 37% and 53% on the disclosed names, and runs working-capital days between 67 and 100 on an operating basis. The gap to the private mid-market sits at 15–35 days of working capital, 2–6 points of gross margin, and 0–4 points of EBITDA margin on a clean comparable basis. That gap is real, it is structural, and it is what the buy-side diligence team will surface against a seller who has not done the prep work. Here is the working read.
01 The cohort and the methodology
The anchor cohort for this read is five publicly-traded mid-cap-to-large-cap US industrial manufacturers: Caterpillar (CAT), Deere & Co. (DE), Parker-Hannifin (PH), Illinois Tool Works (ITW), and Emerson Electric (EMR). The cohort spans the four operating sub-archetypes that map cleanly to private mid-market industrial manufacturers in our advisory book — heavy-OEM and capital-equipment (CAT, DE), engineered components and motion control (PH), specialty industrial and contract assembly (ITW), and process automation and instrumentation (EMR). Annual financial data is extracted directly from XBRL-tagged 10-K filings on SEC EDGAR for fiscal years 2021 through 2025. We use the latest reported balance-sheet snapshot for working-capital lines and the full-year income statement and cash-flow statement for revenue, COGS, and capex.
Two methodology notes matter for the private-comparable conversation. First, both CAT and DE operate captive finance subsidiaries with multi-billion-dollar finance-receivables portfolios that distort the trade-DSO line if left in. We compute working-capital days on an operating basis — trade AR + Inventory − trade AP — and explicitly exclude finance receivables. The CAT FY25 trade-AR figure of $9.28B excludes approximately $30B of receivables held by Caterpillar Financial; the DE FY25 trade-AR of $5.33B excludes roughly $45B held by John Deere Capital. The second note is sub-sector dispersion: the cohort median is informative, but the band underneath the median is wide enough that private operators should benchmark against the sub-sector archetype closest to their own mix rather than the cohort median directly. The category-level numbers are where the operating story lives.
The public mid-cap industrial cohort is the implicit comparable in every private mid-market diligence room. The disclosure granularity exceeds anything available privately and the operating story is nameable line by line.
02 Working-capital days — where the cohort actually sits
The headline cohort number for working-capital days in Q2 2026 is the FY25 median at 83 days on an operating basis (trade AR + Inventory − trade AP, divided by revenue, annualised). The range underneath that median is wide: Parker-Hannifin at 67 days, Emerson at 76 days, Deere at 83 days, ITW at 86 days, and Caterpillar at 100 days. The dispersion reflects underlying business-model differences — order cycles, customisation depth, distribution model, and captive-finance penetration — not management quality differences. A private mid-market manufacturer benchmarking against the cohort should anchor against the sub-sector archetype, not the headline median.
The trend over the FY21–FY25 window is the more interesting signal. Across the cohort, inventory in absolute dollars climbed materially from FY21 into FY23 as COVID-era safety stock combined with tariff hedging and longer lead times. PH inventory grew from $1.96B (FY21) to $2.91B (FY24) — a 48% increase against revenue growth of 39%. Caterpillar inventory grew from $11.4B (FY21) to $16.8B (FY25), a 48% step-up against revenue growth of 32%. ITW inventory peaked at $2.05B in FY23 and has since unwound to $1.61B by FY25, the cleanest example of the post-COVID destock in the cohort. The cohort-wide pattern is consistent with the HighRadius cross-manufacturing benchmark of DIO climbing from 68 days in 2020 to 74 days in 2023 — the COVID-era inventory build did not unwind by 2023 and has only partially unwound through 2025.
The private mid-market gap to this cohort number is the conversation that matters for our advisory engagements. The Perplexity-cited middle-market benchmarks put private $30M–$300M industrial manufacturers in a 70–110+ day operating WC band, with inventory the biggest drag. Against the cohort median of 83 days, that is a 15–35 day gap on the upper end of the private band. For a $100M revenue private manufacturer, 25 days of working capital is roughly $6.8M of capital tied up unnecessarily — capital that buyers will either price into the deal or expect the seller to release before close. The cohort number is not aspirational; it is the achievable mid-market benchmark that public mid-caps have already demonstrated is feasible. The pre-marketing window of 12–18 months is the time it takes to close it.
03 Gross margin — the mix-shift story is the operating signal
Cohort gross margin for FY25 sits in a wide band depending on the sub-sector archetype. Parker-Hannifin at 36.9%, ITW at 44.1%, and Emerson at 52.8% are the three names with cleanly extractable FY25 gross margin from the XBRL data. The cohort median for the disclosed names is 44.1%. The interesting signal is not the level but the five-year trajectory: PH expanded gross margin from 33.1% (FY21) to 36.9% (FY25), a 380bp gain. ITW expanded from 41.3% (FY21) to 44.1% (FY25), 280bp. Emerson, on the disclosed window, expanded from 49.0% (FY23) to 52.8% (FY25), another 380bp. The cohort companies have demonstrably re-pivoted their mix toward engineered, customised, automated, and aerospace-or-software-adjacent product lines — and the gross-margin expansion is the operating proof.
The onshore-content and tariff backdrop
The reshoring and tariff-policy backdrop matters for the gross-margin story because it has changed both the cost side and the pricing side of the cohort's P&L. On the cost side, the ABF Journal middle-market credit study reports that advance rates on imported inventory have dropped from approximately 50% pre-2024 to 35–40% in 2025, while domestic inventory commands 55–60% advance rates. That is a structural financing premium for onshore content that flows directly into the working-capital cost of the goods sold. On the pricing side, ISM's December 2025 manufacturer survey reports that 32% of manufacturers plan to pass on all tariff-related cost increases via higher selling prices, with another 42% planning a combination of pricing and absorption, and only 6% saying tariffs will not affect costs. 86% of manufacturers expect to pass on at least some cost increases. The cohort companies with pricing power — PH in aerospace, ITW in specialty industrial — have used that power to widen gross margin against the tariff backdrop; the cohort companies without it have absorbed the cost.
What this means for the private operator
The private mid-market industrial manufacturer cohort runs gross margin at 20–35% per the GF Data and Lincoln International private-market benchmarks, against a public cohort median of 44%. That is the structural 6–10 point gap that shows up against the engineered-component sub-archetype of the cohort (PH, ITW) and the larger 15+ point gap that shows up against the automation-and-software-adjacent archetype (EMR). The gap closes — partially — when private operators (a) systematically rationalise the SKU long tail using landed-cost-by-SKU profitability work, (b) renegotiate input contracts to reflect tariff-and-freight reality, and (c) re-mix the book toward customised, engineered, or specialty work where pricing power is structurally higher. Our work on WIP standard-cost variance is most often the first lens for the gap. The cohort companies have demonstrated the mix-shift is feasible. It takes 3–6 quarters of intentional book-rebalancing rather than a one-quarter pivot.
04 Capex intensity — the reshoring step-up is in the data
Cohort FY25 capex as a percentage of revenue runs at a 2.6% median, with a range of 2.2% (Parker-Hannifin) to 4.4% (Caterpillar). This is meaningfully below the 3–5% rule-of-thumb baseline most operators carry for industrial manufacturing, and it tells you something specific about the cohort: the high-margin, asset-light, engineered-component archetype (PH, ITW, EMR) genuinely runs at 2–3% capex intensity on a sustained basis. The heavy-OEM archetype (CAT, DE) runs closer to 3–4%. The cohort median understates the maintenance-capex baseline because the asset-light names skew the centre.
The more important signal is the five-year capex acceleration. CAT capex intensity moved from 2.1% in FY21 to 4.4% in FY25 — a step-up of 230bp, with the absolute capex figure rising from $1.09B (FY21) to $2.82B (FY25), a 158% increase against revenue growth of just 32%. DE capex intensity moved from 1.9% to 3.0% across the same window. PH from 1.5% to 2.2%. ITW from 2.0% to 2.6%. Every name in the disclosed cohort has stepped up capex intensity by 50–230bp over five years. The aggregate move tracks the reshoring and onshore-capacity build that IndustrialSage has documented at $1.668 trillion in announced US manufacturing investments since 2025 across 137 companies and 35 states, and that Tema ETFs has tracked at approximately $1.85 trillion across IRA, CHIPS, and IIJA-supported commitments.
The capacity-utilization context matters because the cohort is investing aggressively into a backdrop where manufacturing utilization sits at 75.7% on the FRED MCUMFN series for April 2026 — well below the 79%+ "tight" threshold that historically triggers capex. The cohort is not spending because lines are pinned. The spend is reshoring, automation, and tariff-hedging — strategic, not cyclical. For the private comparable conversation, this matters because most private mid-market manufacturers in the $30M–$300M band are not capex-accelerating. They are running at the historical 3–5% rule-of-thumb maintenance baseline or below it. That gap is structural and it will show up in the diligence room as either (a) a documented maintenance backlog in the QoE, or (b) a buyer adjustment to "normalised" capex that lowers the going-forward EBITDA the multiple is applied against. Our companion read on the factory-floor capex decision for a $1M equipment purchase is the reference for how this conversation usually goes.
05 The private-vs-public operating gap, quantified
Aggregating across the three metrics above against the GF Data, RSM, Lincoln International, and PCE benchmarks for private mid-market industrials in the $30M–$300M revenue band, the structural operating gap to the public cohort runs roughly as follows. Working-capital days: private at 70–110+ days versus public cohort median 83 days — a 15–35 day disadvantage on the upper end of the private band. Gross margin: private at 20–35% versus public cohort median 44% — a 6–10 point gap against the engineered-component archetype, a 15+ point gap against the automation archetype. Capex intensity: private often reports 2–5% versus public 2.6–4.4% — and the private capex line frequently understates the true maintenance baseline because of deferred work that has not flushed through the books. EBITDA margin: private at 10–18% reported (often elevated by sponsor-style add-backs) versus public cohort 12–20% on a clean comparable basis — a 0–4 point gap on the comparable basis, wider after the QoE adjusts the headline EBITDA.
The gap is not a quality indictment of the private operator. It is the structural difference between a $20B-revenue public industrial with ERP discipline, captive-finance leverage, and global procurement scale and a $100M-revenue private manufacturer that has built a profitable business without those advantages. The gap is also not uncloseable. In our engagements, the working-capital gap is the line that most reliably closes in a 12–18 month sell-side prep — the SKU rationalisation, terms renegotiation, and inventory-discipline work compounds. The gross-margin gap is closeable in 3–6 quarters of intentional book-rebalancing toward engineered or specialty work where pricing power is structurally higher. The capex gap is the trickiest because it usually requires the deferred-maintenance flush to land in the headline before the company opens marketing, and that lands in the diligence room as either a one-quarter EBITDA hit or a documented maintenance backlog that buyers will price in.
06 Sub-sector archetypes — benchmark against the right cohort member
The cohort median is a useful anchor, but the operating story lives in the four sub-sector archetypes the cohort spans. Private mid-market operators should benchmark against the archetype closest to their own mix.
Heavy-OEM and capital-equipment — the CAT/DE archetype
The heavy-OEM cohort runs higher working-capital days (CAT 100, DE 83 on an operating basis), driven primarily by elevated DIO from long lead times, complex BOM, and the WIP buffer for configuration and late customisation. Gross margin sits in the high-20s to low-30s on the cohort 10-Ks, with operating margin around 15–20%. Capex intensity sits in the 3–4% maintenance range with growth-capex layering on top in expansion years — CAT is currently in an expansion year at 4.4%, the highest level in the 5-year window. Private operators in this archetype — fabricated metal, custom machinery, capital-equipment subassembly, infrastructure components — should expect to benchmark against working-capital days of 90–110 and capex of 4–6% to look like an investable public-comparable. The reshoring cycle is the tailwind; the maintenance-capex discipline is the lever.
Engineered components and motion control — the PH archetype
PH at 67 operating working-capital days, 36.9% gross margin, and 2.2% capex intensity is the cleanest "asset-light, engineered, customisation-driven" archetype in the cohort. Aerospace mix and the post-Meggitt integration have lifted gross margin 380bp over five years. Private operators in this archetype — engineered fasteners, fluid power, custom electromechanical, instrumentation components — should expect to benchmark against the 65–80 day working-capital range and the 35–40% gross-margin range. The lever is the engineered-customisation mix (away from commodity assembly) and the after-market service tail; the capex discipline is structurally easy once the mix is right.
Specialty industrial and contract assembly — the ITW archetype
ITW at 86 operating working-capital days, 44.1% gross margin, and 2.6% capex intensity is the textbook "80/20 management model" archetype — the structurally high gross margin reflects deliberate SKU pruning, customer concentration on the profitable accounts, and pricing discipline. Private operators in this archetype — specialty industrial, contract assembly, niche industrial consumables — should expect that the gap to ITW is closeable via SKU rationalisation, customer-mix work, and pricing discipline more than via capex. The working-capital line is the surprise: ITW carries more inventory days than PH or EMR because the customisation depth requires more WIP, not less.
Process automation and instrumentation — the EMR archetype
EMR at 76 operating working-capital days, 52.8% gross margin, and 2.4% capex intensity is the highest-gross-margin name in the cohort, reflecting the deliberate re-pivot to process automation and software-adjacent product (NI Corp acquisition closed FY23, Climate Technologies divestiture creating Copeland JV). Private operators in this archetype — process instrumentation, automation components, industrial software-and-hardware bundles — should benchmark against the 50%+ gross margin range and the sub-3% capex intensity range. The gap to EMR is usually the software-content gap and the recurring-revenue gap; closing it is a strategic-product decision, not an operating tweak.
07 What the QoE will surface against this benchmark
Three diligence lines in our advisory engagements on private mid-market industrial manufacturers map directly to the cohort benchmark above. Each can move the effective multiple by 0.3–1.0 turns of EBITDA on its own.
- 01 The working-capital normalisation: If the private operator runs 95+ days of operating working capital against a public cohort comparable in the 67–86 range, the buyer's QoE will compute a "normalised" working-capital level and the gap will show up as either a permanent EBITDA adjustment for the WC carrying cost, or — more often — a higher net-working-capital peg that lowers the cash at close. Either way the deal economics move against the seller. The fix is the 12–18 month inventory-and-receivables discipline programme, which our advisory book runs in nearly every industrial engagement.
- 02 The maintenance-capex backlog: If reported capex has run at 1–2% of revenue for three or more years against a sub-sector comparable that benchmarks 3–4%, the buyer's QoE will compute a deferred-maintenance backlog and either (a) take it directly off the headline EBITDA as a permanent adjustment, or (b) apply a "normalised capex" haircut to the going-forward FCF the multiple is applied against. The fix is to document the actual maintenance state — preferably with an external engineering review — and address the largest items before opening marketing, or alternatively to surface and quantify the backlog in the sell-side QoE so the buyer cannot use it as a retrade lever.
- 03 The gross-margin trajectory line: A trailing-24-month gross margin that has been compressing under input-cost pressure or tariff exposure will be assessed against the cohort's ability to widen gross margin through the same period. The cohort has demonstrably done it (PH +380bp, ITW +280bp, EMR +380bp on disclosed periods). A private operator who has lost 100–300bp of gross margin over the same window is on the wrong side of the cohort story and needs to document the operational fix — input renegotiation, SKU rationalisation, channel re-mix — that returns gross margin to the historical level before a process opens.
08 What we are watching into Q3 2026
Three signals matter into Q3 2026 for the cohort. First, whether the capex acceleration in CAT and the engineered-component names continues through fiscal H2 — the trajectory tells you whether the reshoring cycle has further to run or whether it has front-loaded. Second, whether manufacturing capacity utilization (FRED MCUMFN) breaks above the 76% level it has been pinned near since mid-2024 — if utilization moves through 78–80%, the cohort's strategic capex will compound with cyclical capex and the working-capital days line will widen further. Third, whether the ISM Manufacturing PMI holds expansion (52.4–52.7% in Feb–Apr 2026) or rolls back below 50 — the cohort's gross-margin trajectory is more sensitive to demand than the headlines suggest. Each signal moves the cohort numbers above by approximately 50–100bp on capex intensity or 5–10 days on working capital. We publish this read quarterly; the Q3 2026 update is scheduled for August 2026.
