Private Equity Is Buying Defence in Bulk, and Paying Less for Each Piece

What's New

Defence deal count nearly quintupled in a year while deal value did not come close to keeping up, which means sponsors are buying many more companies and paying far less for each. Private equity closed 112 aerospace and defence deals in the second quarter against 53 a year earlier, while deal value fell to $6.5 billion from $15.3 billion, according to PitchBook's Q2 2026 Aerospace and Defense Report, published August 20 under the subtitle More deals, smaller check sizes. Inside defence the gap is starker still: deal count went from nine to 44, a 388.9% jump, while value roughly doubled to $2.4 billion. PitchBook flags the arithmetic trap directly, since a move from single digits to double digits produces a headline percentage far larger than the underlying dollar change. The growth is real, but it is consolidation growth, not platform growth.

Why It Matters

Sponsors are responding to a durable demand signal, defence budget expansion driven by conflicts in Iran, Ukraine and Gaza, but they are expressing it through many small acquisitions rather than large platforms. That is a different capability than writing one large cheque, because it requires integration bandwidth, regulatory clearance at volume and the ability to run diligence economically at small ticket sizes. For LPs, it means defence exposure now arrives through dozens of positions rather than a few, which changes both the correlation profile and the reporting burden. For technology platforms, high volume low value transactions in a regulated sector are among the most operationally demanding portfolios to service.

Big Picture Drivers

The demand signal is government, not commercial: Defence deals stalled in Q2 2025 while the new US administration set its spending strategy, then accelerated once the budget proposal landed in the second half of that year.
Small numbers produce large percentages: PitchBook flags explicitly that a move from nine deals to 44 generates a headline growth rate far larger than the underlying dollar change of a few billion.
Average cheque size is shrinking across the sector: The pattern holds at the total aerospace and defence level and is sharper in defence, where count growth outran both airlines and commercial aerospace.
Exits are working through public markets again: Five public listings in Q2 and eight in the trailing year against two in the prior twelve months, a genuine reopening rather than a single event.
Buyouts now outnumber acquisitions as an exit route: 50 buyouts against 26 acquisitions on a trailing basis, meaning sponsors are selling to each other more often than to strategics.
The sector's share of private equity has roughly doubled: Aerospace and defence took 4.7% of all private equity deal count in Q2 against 2.5% a year earlier.

By The Numbers

112 deals in Q2 against 53, a year earlier, with deal value falling 41.4% sequentially over the same period.
80 defence deals in the first half against 20, a 300% increase in six months.
$5.8 billion of first half defence value against $2.4 billion, up 144.5%, which is fast growth but far slower than the count.
$64.5 billion of trailing twelve month deal value, against $53 billion, growth of 21.7% on a 57.7% increase in transactions.
$26.8 billion of exit value in 2026 to date against $17.7 billion for all of 2025, on an estimated 76 exits.
3.7% of private equity deal value against 4.7% of deal count, the clearest single expression of the smaller cheque pattern.

Key Trends to Watch

Integration capability becomes the differentiator: A strategy built on dozens of small acquisitions succeeds or fails on operational execution, not on entry multiple, and that will separate sponsors within two years.
Public listings test the marks: With five listings in one quarter, the sector now has visible comparables that private valuations have to answer to.
Space and defence keep converging: Space systems and satellites is a tracked defence segment here, and the same demand is driving PitchBook's separate finding that defence procurement underwrites space production.
Budget durability is the whole thesis: The deal surge rests on sustained militarisation, and any budget reversal hits a portfolio built at small scale across many holdings harder than one built around a few platforms.
Government IT and cybersecurity carries the count: The segment breakdown shows it among the largest contributors to defence deal volume, which is where sponsors find fragmented targets at accessible prices.

The Wrap

This is a sector where the percentage growth headline and the underlying economics point different ways. Deal count says private equity has discovered defence and moved in decisively. Deal value says it is buying small, fragmented assets at cheque sizes that make sense only if consolidation works. Both are true, and the second one determines the returns. For technology providers, the pattern is the same one showing up in construction and trade services: sponsors executing many small acquisitions in regulated sectors need consolidated reporting across numerous entities with inconsistent data, and the value is in making that cheap rather than making it sophisticated.
