KKR looks to sell CoolIT, maker of data centre cooling technology

KKR has put CoolIT Systems up for sale (process in early stages) alongside minority owner Mubadala, with the Financial Times reporting potential interest above US$3.0 billion. CoolIT generates annual revenue exceeding US$300 million, employs over 650 people, holds ~120 patents and supplies liquid-cooling systems used in 7 of the top 10 supercomputers and by four of the top five server manufacturers and four of five hyperscalers. The potential divestment reflects strong demand from the AI-driven data-centre buildout and could attract strategic buyers in data-centre infrastructure and server OEMs.

Analysis

A private-market transaction that routes significant value into IP-heavy liquid-cooling creates a new public comp that will reprice small-cap suppliers and strategic acquirers. Expect a two-track rerating: pure-play cooling/thermal names can gap higher as takeover targets, while larger infra OEMs re-evaluate capex payback on in-house vs. buy strategy. This will be most pronounced over a 3–12 month window as buyers translate deal comps into bids.

Second-order supply-chain and geopolitics will matter more than headline multiples. Manufacturing footprints split across North America and Asia create operational risk if export controls or local policy tighten; that risk can impair deal certainty and lengthen integration timelines from quarters to multiple years. Separately, the economics of retrofit vs. greenfield matter — modest incremental capex to enable higher rack density could shift long-term revenue capture toward hyperscalers that own their campuses, compressing leasing optionality for some REITs.

Key near-term catalysts to watch are announced buyers, patent/ITR diligence outcomes, and hyperscaler capex cadence; any of these can move public peers by 15–40% within months. Tail risks include rapid commoditization of fluid components and successful insourcing by large cloud platforms, which would cap strategic multiples and reverse the rerating within 6–24 months.

Key Decisions for Investors

• Long KKR (KKR) — 12-month horizon. Size 2–4% NAV. Rationale: PE realization tailwind and potential distributable proceeds could boost NAV/GC and drive 15–25% upside if a high-multiple exit prints; downside ~8–12% if process stalls. Use a 6–9 month call spread (buy 12-month ATM, sell 12-month +25% strike) to cap cost.
• Long small-cap liquid-cooling supplier (ASETEK:OSE) — 9–12 months. Size 1–2% NAV. Rationale: most exposed pure-play should rerate on new strategic comps; target +40% upside if takeover chatter resumes. Risk of commoditization and margin pressure implies stop-loss at -30%.
• Long Vertiv (VRT) — 6–12 months. Size 2–3% NAV. Rationale: strategic consolidator optionality and OEM pricing power in retrofit projects; target +25% upside, downside -12% on cyclicality. Consider buying March 12-month calls to lever upside with defined premium.
• Tactical short pair: short Equinix (EQIX) or Digital Realty (DLR) vs long ASETEK or VRT — 3–6 months. Size neutral delta. Rationale: hedge view that hyperscaler insourcing and higher-density on-prem deployments will pressure leasing growth; expect relative underperformance of large REITs by ~10–15% in adverse scenario. Tight stops at +8% on the short leg.
