Jan 2026 Pulse

Jan 2026 in brief.

Seventeen events, eight of them M&A, with a ≥$4.7B floor across eleven disclosed amounts. Eaton completed its $1.55B purchase of Ultra PCS (aerospace controls and mission-data systems); the Department of War announced a $1B convertible preferred investment in L3Harris Missile Solutions, the solid-rocket-motor supplier for PAC-3, THAAD and Tomahawk, under its industrial-base program (IBAS); and AE Industrial Partners agreed to take a majority stake in L3Harris’ commercial space propulsion business — relaunched as Rocketdyne — at an $845M enterprise value. Parsons paid $375M for Altamira (IC analytics and SIGINT). Five Series B rounds between $100M and $200M made January the broadest mid-stage month on the tape: Harmattan AI (Dassault Aviation, $200M), JetZero ($175M, B Capital), Defense Unicorns ($136M, Bain Capital Tech Opportunities), Cambium ($100M, 8VC) and Northwood Space ($100M, Washington Harbour and a16z). Onebrief’s $200M Series D came with its undisclosed purchase of Battle Road Digital. Four sponsor deals went undisclosed: Beaufort’s carve-out from Survitec (Capitol Meridian, Stellex), J.F. Lehman’s Wellman Dynamics, and add-ons by AxioAero and Aurex; Elliott’s growth investment in Stratolaunch was also unpriced.

January is the clearest picture of the 2026 buyer mix: an industrial strategic (Eaton), a government balance sheet (the Department of War into L3Harris), a sponsor carve-out (AE Industrial and Rocketdyne), a services acquirer (Parsons) and a venture-backed company buying with fresh capital (Onebrief). Five $100M–$200M Series Bs in one month also mark the point where mid-stage defense rounds stopped being exceptional. Six of seventeen events undisclosed (35%) is the highest ratio in the archive — sponsor add-ons do not print prices, so the public floor understates January’s real volume.

Activity vs each domain’s own baseline.

Each cell is the number of publicly announced deals in that domain and month. Color compares the month with that domain’s own average over the months shown — not a scale shared across domains — so a dark cell in a small domain means “busy for that domain”, not “large in dollars”. Domains with fewer than 12 events in the window are shown in gray without color. Absolute totals across all 24 months are on the archive home.

No domain moved outside its normal range.

No domain yet has enough history for a percentage callout. We flag a domain only when its last three months differ from the prior three by 30% or more and it has at least 36 events in the trailing 12 months. Smaller samples stay as raw counts on the heat map; we never quote month-over-month percentages.
