01

Tariff discipline

Is tariff engineering a real competency, or are we just mistaking reactivity for strategy?

What I'm seeing

The COGS shock has normalized, but the capability hasn't.

US Section 301 tariffs on Chinese imports remain elevated across multiple categories, and Morgan Stanley's reshoring thesis, articulated by Chris Snyder, names the shift directly: companies now have to serve the US market from US production, because the 2024 inventory-buffer and pass-through playbook is exhausted. At portfolio-company level I'm seeing a quiet divergence. Some management teams have built genuine tariff engineering discipline. HS-code-level exposure mapping, origin-shifting models, dual-qualified suppliers, scenario-based FP&A that stress-tests covenants at multiple tariff levels. Others declared victory because they raised prices once in 2024 and held margin for two quarters. Those are very different companies, and they're about to be valued very differently at exit.

Whether "tariff engineering" is actually a capability or a label for whatever procurement did this quarter.

True tariff engineering (the kind that survives an IC review, diligence, and a hostile lender cross-examination) requires a durable operating model: HS-code fluency at line-item level, origin documentation that holds up to CBP audit, a trade compliance function reporting into finance rather than sitting as a procurement afterthought, and a scenario library that lets the CFO answer "what happens if the Section 232 exemption lapses" in minutes. Most mid-market industrials I diligence do not have this. They have a spreadsheet, an energetic VP of procurement, and an accounting firm on retainer. That is not the same thing, and I keep wondering whether sponsors who've marked their portfolios "tariff-prepared" would survive a serious post-mortem on what that actually means.

Whether tariff volatility is an operating-partner deliverable or a board-level enterprise risk.

It's both, and the failure mode is that it's treated as neither, delegated to procurement, a team with neither the authority nor the capital to reshape a supplier footprint. In the platforms where I'm seeing progress, the operating partner has pulled tariff exposure out of procurement and made it a CFO-owned KPI tied to forecast quality; the board sees it quarterly as an enterprise risk disclosure; diligence at next-platform acquisition builds a tariff-stress scenario directly into the model. The question I don't have a clean answer to: at what point does tariff capability become a valuation premium at exit rather than table stakes? Because the firms treating it as table stakes today will be explaining multiple compression at their next LP meeting.

02

Gulf & energy

How do we price a portfolio company whose energy and feedstock curves just changed shape?

What I'm seeing

Energy and feedstock exposure is the single most mis-modeled line item in mid-market industrial LBOs.

Per the US EIA's February Short-Term Energy Outlook, Brent has repriced sharply off late-2025 levels and base-case scenarios now run to roughly $115 in Q2 before settling closer to $88 in Q4. With escalation scenarios well above that. For platforms with energy-intensive production, steel, specialty chemicals, glass, plastics, aluminum, fertilizer. This is not a one-quarter event; it's a structural re-pricing of unit economics. I'm seeing three cascading effects. Direct energy costs per unit up 18–40% depending on fuel mix. Freight and war-risk insurance premiums reported at roughly 10× for any Gulf-exposed routing, per Lloyd's market commentary. And. The one sponsors are missing, tier-2/tier-3 suppliers in energy-importing economies (India takes roughly 45% of Gulf refined products) are under margin stress that will show up as missed deliveries, quality drift, or price demands over the next two quarters.

Whether the LBO models I'm reviewing for 2026 vintages are using honest energy assumptions.

Most management cases and sponsor models I've seen this quarter use a $70–80/bbl Brent base case with a $90 sensitivity. EIA's forecast is now $115 at peak, averaging closer to $96 for the year (the difference between those two assumptions, run through an energy-intensive P&L and debt service stack) is enough to consume a full year's planned distributions and, in some cases, trigger covenant breaches (the uncomfortable question: are sponsors underwriting to a model they believe, or a model they need to get the deal done? The honest answer, for at least some 2026 vintages) is the second. That's a problem that doesn't show up in a CIM. It shows up in a Q3 earnings call eighteen months from now.

Whether fertilizer and urea disruption is the sleeper issue for food-processing and ag-adjacent portfolios.

Roughly a third of globally-traded urea and a fifth of ammonia normally transit the Strait of Hormuz; Qatar's largest urea facility has suspended operations. This has direct consequences for any PE-backed portfolio exposed to agricultural inputs, food processing, specialty nitrogen chemistry, or packaging that depends on derivative chemistries. A kind of second-order exposure that rarely makes it into an investment memo because it lives three tiers up the supply chain. The question I keep posing to sponsors: when was the last time you mapped your portfolio's exposure to a commodity that doesn't appear anywhere in the bill of materials? That's where the next surprise will come from.

03

Logistics as strategy

When did shipping stop being an operational line item and start being a strategic choice?

What I'm seeing

Maritime risk is a board-level enterprise exposure, not a logistics KPI.

The compounding effect of escalating Gulf tensions, Red Sea disruptions, and narrow-channel vulnerabilities at Panama and Malacca has pushed shipping from procurement into the risk committee. Tanker and container traffic has been diverting from Gulf and Red Sea routings in meaningful volume; major carriers including Maersk and Hapag-Lloyd have suspended or materially altered Gulf exposure; Cape of Good Hope rerouting adds 10–14 days and material fuel cost on Asia–Europe lanes (for a PE-backed manufacturer with even moderate international input or output exposure) realized logistics cost over the past year is up 15–35%. That's a materially different story than "freight was up."

Container trucks at an intermodal yard with stacked containers, landed cost and logistics flow — Landed cost is no longer a quarterly variance line, it's a strategic choice being made three reporting layers below the CFO.

Whether sponsors and operators can actually make logistics a strategic decision rather than delegating it downward.

In most mid-market industrials, logistics sits three or four reporting lines below the CEO. The people making routing, carrier, and insurance decisions are career operations managers, excellent at their jobs, but not structured to trade a 12-day delivery extension against a 300bp working capital impact on the quarterly cash forecast. That trade-off belongs to the CFO, and in most portfolios the CFO doesn't see it until it shows up in quarter-end variance. I've started asking portfolio company CEOs a simple diagnostic: "Who in your organization has authority to accept a 2% COGS increase to reduce a geopolitical tail risk?" The most common answer is "no one, actually." That's the gap.

Whether logistics risk should be hedged financially, not just operationally.

A toolkit of freight-rate derivatives, war-risk insurance structures, and portfolio-level freight hedges (until recently the domain of shipping companies and commodity traders) is now showing up in mid-market industrials, not always used well. I'm genuinely uncertain whether this sophistication is worth encouraging at scale or whether it's introducing an unfamiliar category of financial risk to operators unequipped to manage it (the question I'm working through with CFOs: if you're going to treat logistics as a strategic variable) will you treat it like a commodity (hedge it) or like a capability (vertically integrate it)? Because the middle ground, pretending it's still procurement, is what's producing the earnings surprises.

04

Critical minerals

If the US lists 50 minerals as critical, how many of them does my portfolio company actually control?

What I'm seeing

Concentration is structural, and the mitigation timelines are longer than fund lives.

China controls roughly 85% of global critical-mineral refining capacity. The DRC is the sole source of high-grade cobalt. Chile and Argentina anchor the lithium triangle. For industrial portfolios with exposure to batteries, magnets, specialty alloys, electronics, or energy-transition components, the supply-chain dependency isn't diversified, it's geopolitically concentrated in ways that can't be re-engineered on a three-to-five-year PE hold. China tightened export restrictions on graphite, antimony, gallium, germanium, and select rare earths across 2024–2025; Bain's 2025 analysis flagged expected shortages in several categories by 2026–2030 (for a portfolio company whose motors, sensors, or magnets depend on these inputs) this is not an ESG story, it's a supply-continuity and COGS-inflation story.

Whether "we don't use those directly" is the most dangerous sentence in diligence.

When I raise critical-mineral exposure with portfolio company management, the first response is almost always some version of "we don't use those directly." That may be true at the finished-goods level. It's rarely true at tier-2 and tier-3, and almost never true at the capital-equipment level. The motors, drives, sensors, and magnets embedded in the factory itself depend on these inputs. I've started asking a different question: "If China announced an export halt on rare earth magnets tomorrow, how long before you'd miss a customer delivery?" The spread of answers is alarming. It ranges from "we've stockpiled nine months" to "I'd need to call our ops VP to ask." The second answer is the one I worry about.

Whether critical-mineral exposure is a diligence line item yet, or should be.

In the diligence processes I'm seeing, critical-mineral exposure is rarely quantified. At best a footnote under "geopolitical risk" or a slide in the ESG section. That's about to change. Several LPs are starting to ask sponsors for portfolio-level mineral exposure disclosures, and a handful of large allocators are signaling they'll expect it in diligence packs for industrial and energy-transition funds in their 2026–2027 cycles. The unresolved question: at what tier of the supply chain does mineral exposure become the sponsor's responsibility to diligence, rather than the management team's responsibility to mitigate? The industry doesn't have a shared answer yet. It will. The question is whether it arrives before or after the first publicized write-down driven by a mineral-supply shock.

05

AI in operations

Is AI actually changing mid-market manufacturing, or are we documenting the same pilots over and over?

What I'm seeing

The adoption curve is bifurcating faster than aggregate numbers suggest.

Deloitte's 2026 survey says 80% of manufacturers plan to invest 20%+ of improvement budgets in smart manufacturing; West Monroe says 91% of mid-market manufacturers are using generative AI (these numbers feel simultaneously too high and too low) depending on how you define the question. What I actually see in portfolios is a stark two-tier reality. Roughly a quarter of industrial platforms have built real AI-enabled operations: predictive maintenance that's materially reducing downtime, computer vision cutting reject rates in half, demand forecasting that's pulled working capital days out of the system, agentic procurement that flags supplier risk in minutes. The remaining three-quarters sit somewhere between "we've run a pilot" and "our ERP vendor added an AI module." The gap between those groups is widening, and becoming a meaningful driver of exit multiple expansion that sponsors are only just beginning to model.

Industrial warehouse interior at night lit by overhead lights. The operating environment where AI either takes root or doesn't — AI capability in mid-market operations is shifting from differentiator to table stakes. The binding constraint is operator talent, not capital.

Whether "AI adoption" is the right thing to measure at all.

The survey industry is measuring AI adoption because it's measurable. The signal I actually care about is different: whether AI has changed the operating model, or just automated existing tasks. A portfolio company that has deployed seven AI pilots but still runs planning, procurement, and quality on the same pre-AI cadence and decision rights has not really adopted AI. It has bought software. The question I'm asking sponsors is not "how many AI initiatives has your portfolio company launched" but "how has your portfolio company's org chart changed because of AI?" If the answer is "it hasn't," the AI has probably not taken root. That's the test I'm running in diligence, and it's uncomfortable for a lot of management teams.

Whether AI in manufacturing is a value-creation lever or a table-stakes capability at exit.

Two years ago, sponsors could claim AI-enabled operations as a differentiated value-creation story. I'm no longer sure that claim holds. I think AI capability in operations is transitioning from differentiator to ante, and platforms that haven't built it will face multiple compression, not because buyers explicitly discount them, but because the same dollar of EBITDA is produced less efficiently and is therefore less scalable in the buyer's hands. I don't have a clean thesis on where the line sits yet. But I'd offer this provocation: the most important AI investment a mid-market industrial can make in 2026 is probably not a new algorithm, it's hiring a senior operator who can integrate AI into decision rights and operating rhythm. Those people are rarer than the technology itself. Capital isn't the constraint. Organizational design is.

06

Climate & emissions as impairment

Is climate risk still an ESG conversation, or has it quietly become a balance-sheet conversation?

What I'm seeing

Climate risk shows up as insurance cost, asset impairment, and disclosure-driven capital cost, almost never as "ESG."

Three concrete things are happening in industrial portfolios right now. Commercial property and business interruption insurance premiums for Gulf Coast, Southeast, and Texas reshoring sites have increased 15–40% annually for multiple renewal cycles. EU CBAM, California SB 253/261, and CSRD are creating real disclosure costs, capitalized into acquisition models at best, missed and absorbed post-close more often. And physical climate exposure is quietly driving impairment risk at sites where asset life exceeds the climate-stable horizon, as auditors are beginning to notice. None of this shows up in portfolios under the heading "ESG." It shows up as premium creep, disclosure compliance costs, consultant fees, deferred capex, and occasionally a goodwill write-down.

Whether PE is underpricing climate risk because it's being measured in the wrong currency.

The discipline has a category error baked into its current approach. Climate risk gets assigned to ESG teams, who report in emissions tons and disclosure compliance (the actual financial consequences, insurance premiums, physical asset impairment, capex deferral) siting decisions, disclosure-driven cost of capital, show up on finance and operations dashboards with no label connecting them back to the climate thesis. That makes it very hard to tell whether the portfolio is paying the climate bill, and if so, where. The question I'm asking CFOs and operating partners: "If I gave you a line on your P&L called 'climate cost,' what would go into it?" Almost no one has a good answer. I don't think the line is zero. I think the cost is distributed across accounts in ways that make it invisible.

Whether 2026–2028 is when "stranded asset" stops being a fossil-fuel phrase and starts applying to mid-market industrial sites.

Here's the thesis I'm increasingly uncomfortable with, not because I disagree, but because I think it's right and not being priced: a meaningful number of industrial manufacturing sites acquired in the 2021–2023 vintage were sited for labor, logistics, and tax reasons that assumed a climate envelope that no longer describes the decade ahead. Some will need significant adaptation capex, or relocation, or simply won't be economic to operate at their current insurance cost. The industry term is physical-climate impairment. It does not yet appear in most LBO models. I'm working through this with a few sponsors now, and the resistance isn't disagreement, it's a reasonable worry about what it would mean to name the risk in a memo that goes to LPs. That's exactly the conversation that needs to happen, and the platforms that have it first won't surprise their LPs in 2028.
