BizLink Holding closed an $850 million all-cash acquisition of Interplex Datacom from Blackstone, gaining immediate exposure to the liquid-cooled server connector market and high-speed interconnect assemblies for AI clusters. The transaction positions the Taiwan-based manufacturer inside hyperscaler supply chains at a moment when data center thermal density is forcing architectural redesign.
Interplex Datacom manufactures precision connectors and thermal management components for rack-scale deployments. The business generates revenue from repeat orders tied to GPU cluster buildouts, liquid cooling retrofits, and 400G-to-800G network upgrades. BizLink operates adjacent product lines—cable assemblies, power distribution harnesses—but lacked the high-margin connector portfolio that Interplex brings. Blackstone held the asset for four years through its Interplex Holdings platform, which carved out non-core divisions in 2023 ahead of this exit.
The deal matters because connector revenue is levered to two simultaneous infrastructure shifts. First, liquid cooling adoption is accelerating faster than public guidance suggested six months ago. Hyperscalers are retrofitting air-cooled racks with direct-to-chip cold plates, and each conversion requires new bulkhead connectors, manifold assemblies, and quick-disconnect couplings. Interplex holds design wins with two of the three largest cloud providers for these components. Second, 800G Ethernet is moving from lab trials to volume production. Network switch OEMs are tooling for Q3 2025 shipments, and the connector bill-of-materials per rack rises 40% when migrating from 400G to 800G due to higher lane counts and tighter impedance tolerances. BizLink now controls both the copper cable assembly and the mating connector, capturing more value per rack.
Operators should track three developments over the next six months. First, watch for BizLink's Q2 2025 earnings call in early August, when management will quantify Interplex's backlog duration and name any incremental design wins post-acquisition. Second, monitor whether Blackstone retains minority economics through earnouts or warrants—the press release disclosed only the headline figure, leaving open the possibility of performance-based consideration tied to 2026-2027 revenue targets. Third, observe how BizLink allocates the Interplex engineering team. If the connector designers migrate into BizLink's existing R&D org in Fremont, integration is straightforward. If they remain siloed in Singapore under the old Interplex structure, expect product roadmap delays and customer confusion.
$850 million for a connector business signals that Blackstone's private equity math worked. The firm likely paid mid-single-digit EBITDA multiples when carving Interplex out of a larger industrials portfolio in 2020, then exited at high-teens multiples as AI capex inflated recurring connector orders. BizLink is paying for installed base and forward backlog, not historical earnings. The question now is execution cadence. Liquid cooling connectors ship in six-to-nine-month lead times from design freeze to volume production. If BizLink stumbles on integration, competitors like Amphenol and TE Connectivity will fill the gap before hyperscalers re-source.
