What does the budget request actually tell a supplier?
That the direction is up and the amount is not yet settled. The fiscal 2027 US defence budget request totalled roughly $1.5 trillion, representing a 44% increase year over year (Capstone Partners, Training and Simulation Sector Update, 2 June 2026, citing the fiscal 2027 US government budget).
A request is an opening position in an appropriations process, not money a contractor can plan against. It is nonetheless the strongest forward demand signal in the industrial economy, because appropriations rarely move far from requests in direction even when they move in level, and because contractors and their lenders both read it as a planning input.
What is already appropriated is the more useful number for a business selling in the next twelve months. For fiscal 2026, training investments rose 7.8% year over year to $159.7 billion, or 16.6% of the total budget (same source). That is enacted spending working its way into contract awards now.
The distinction matters for how an owner presents a growth story. Enacted appropriations plus a contract or a qualified position is a diligenceable forward revenue case. A budget request plus a market share assumption is a projection, and buyers in this cycle have become notably less willing to pay for projections.
Is the spending converting into transactions?
Yes, and the conversion is visible in the sub-sectors closest to the appropriated money. Training and simulation transaction volume rose 133.3% year over year, or eight deals, to fourteen transactions year to date in 2026, with sponsor dealmaking up four deals year over year to six after two stagnant years (Capstone Partners, Training and Simulation Sector Update, 2 June 2026).
The forward forecast for the wider sector is the strongest across industrials and services. Aerospace and defence deal volumes are forecast up 14% in 2026, against manufacturing at plus 5% and automotive, engineering and construction and business services all forecast to decline (PwC, Global M&A trends in industrials and services 2026 mid-year outlook, 23 June 2026, on LSEG data to 31 May 2026).
Public market appetite has followed. Defence and aerospace is one of the named themes carrying the 2026 listing market, alongside energy and biotech, with Americas industrials taking eighteen listings and $100 billion of proceeds in the first half, though a single very large aerospace transaction accounts for most of that proceeds figure (Renaissance Capital, 2Q 2026 US IPO Market Review, 1 July 2026; EY Global IPO Trends Q2 2026, published 7 July 2026).
We should be honest about the limits of the transaction data available. The most recent dedicated annual study of aerospace and defence transactions we could locate carries fiscal 2024 data, showing US transactions up 15% in 2024, which is roughly two years old and is not a current reading. The forward-looking figures above are the current evidence; the sector-wide annual series is not.
| Element | Figure | How firm it is |
|---|---|---|
| Fiscal 2027 budget request | Roughly $1.5 trillion, a 44% increase year over year | A request, not an appropriation; direction is strong, level is unsettled |
| Fiscal 2026 training investment | $159.7 billion, up 7.8% year over year and 16.6% of the total budget | Enacted spending converting into awards now |
| Training and simulation transactions | 14 transactions year to date 2026, up 133.3% or eight deals year over year, with sponsor deals up four to six | Completed transactions; the firmest evidence in this table |
| Forward volume forecast | Aerospace and defence deal volumes forecast up 14% in 2026, the strongest across industrials and services | A published forecast on data to 31 May 2026, not an outturn |
| Annual sector transaction study | US aerospace and defence transactions up 15% in 2024 | Roughly two years old; carried as trend context only and not a current reading |
“Suppliers in this sector make the same presentation mistake as everyone else, which is to lead with the budget headline. The buyer already knows the headline. What they want is the programme, the qualification, the position on the drawing and the appropriated line it is funded from. One of those is a market view and the other four are the business.”
How does this fit the wider rotation in capital?
It is the same rotation. Capital has moved decisively toward heavy assets with low obsolescence, and defence sits inside that cohort along with energy, materials and environmental services. That group captured 31.2% of US private equity deal value in the first quarter of 2026 against a steady share of roughly 14% across 2016 to 2024 (PitchBook via Blue River Financial Group, published July 2026).
The middle-market pricing evidence moved with it. Manufacturing multiples improved to 7.2x from 6.6x while business services eased to 7.0x from 7.3x, the first time in years that heavy assets overtook asset-light services on multiple (Mercer Capital, Middle Market Transaction Update Summer 2026, on GF Data figures as of Q1 2026). Precision manufacturing, which contains a substantial share of qualified defence and aerospace content, traded at 10.1x EV/EBITDA across 2023 to the first quarter of 2026 against 9.6x across 2020 to 2022 (Capstone Partners, Precision Manufacturing Market Update, 6 May 2026).
The industrial-capacity argument sitting underneath this is straightforward and does not require any view about geopolitics to hold. A programme cannot be delivered faster than the supply chain can produce it, decades of consolidation removed capacity from that supply chain, and rebuilding it requires either capital investment or acquisition. Acquisition is faster, which is why qualified suppliers are being bought.
The hard-asset framing that circulates alongside this is worth treating carefully. It is a portfolio argument about asset classes rather than a statement about any operating business, and we would not extend it into advice about how anyone should position their own capital. What is defensible at the sector level is narrower: businesses with physical capacity, certified positions and appropriated demand have been repricing upward, and the published data above shows it.
What does a buyer underwrite in a defence supplier?
Qualification, programme exposure, contract type and compliance posture, in roughly that order. Revenue growth matters far less than whether the business holds a position a competitor cannot obtain quickly.
Qualification is the barrier and it is verifiable. Being specified on a drawing, qualified on a programme, holding a facility clearance, carrying the relevant quality certification or being a sole or limited source on a part number all mean displacement requires the customer to re-qualify somebody else, which takes time and money the customer would rather not spend. That is what a buyer pays for in this sector.
Programme exposure is the corresponding risk. Concentration in a single programme, particularly one that is late in its lifecycle or subject to review, is the sector's version of customer concentration and it prices the same way. The useful disclosure is content by programme, with the funding status and expected lifecycle of each, presented at the outset rather than reconstructed by a buyer.
Contract type and compliance posture determine whether the earnings are what they appear to be. Fixed-price development work carries risk that cost-plus does not; government accounting, cost allowability and pricing compliance obligations create liabilities that surface in diligence; and export control and security requirements can restrict who is permitted to buy the business at all. That last point is the one most often discovered late, and it changes the buyer list rather than the price.
What could go wrong with this thesis?
Appropriations, timing and the macro environment, and none of them is currently priced into the sector commentary. The first is the simplest: a request that is not appropriated at the requested level converts into a smaller demand signal, and the conversion happens on a political calendar rather than a commercial one.
The second is that defence procurement is slow even when funded. Money appropriated in one fiscal year reaches a subcontractor several steps down the supply chain considerably later, and a business underwriting its forward plan on an appropriation rather than on a purchase order is taking timing risk it does not control.
The third is the general macro case, which is published and specific. In the more severe of the scenarios set out in April 2026, global growth falls to 2% in both 2026 and 2027 with inflation above 6% (IMF April 2026 World Economic Outlook, cited by PwC, 23 June 2026), and government debt across the developed economies reached a record $61 trillion in 2025 (OECD, cited in the same PwC outlook). A fiscal environment under that kind of pressure is not one in which any spending line is beyond examination.
None of that argues against the sector. It argues for evidencing the specific position rather than the theme, which is the same conclusion the reshoring data forces in manufacturing generally. A qualified position on a funded programme survives an appropriations argument. A slide about a more dangerous world does not.
