Johnson Controls has entered a definitive agreement to acquire Boston-based Alloy Enterprises, with the transaction expected to close in the third quarter of 2026. Alloy Enterprises specializes in a proprietary metal additive manufacturing process branded as Stack Forging, which produces fully dense components featuring complex internal microfluidic channels. This acquisition integrates Alloy's thermal management capabilities directly into Johnson Controls' industrial portfolio, specifically targeting the high-performance computing and data center cooling sectors. The deal marks a strategic move to internalize advanced manufacturing methods for high-efficiency heat exchange systems.

This acquisition reflects the ongoing trend of large-scale industrial firms absorbing specialized additive manufacturing technology providers to secure supply chain control for critical components. Alloy Enterprises differentiates itself from traditional LPBF service bureaus by focusing on vertically integrated production of metal parts that require high thermal efficiency and specific internal geometries. As data center power densities increase, the demand for sophisticated cooling solutions is projected to grow significantly through 2033. By bringing Stack Forging in-house, Johnson Controls addresses a specific bottleneck in the production of high-performance fluid systems that are difficult to manufacture using conventional machining or standard metal 3D printing techniques.

For Johnson Controls, the immediate priority is the successful integration of Stack Forging into their existing manufacturing workflows to scale production for data center infrastructure. Users of these thermal management components should focus on how this transition impacts lead times and design iteration cycles for future cooling system deployments. The value of this deal rests on whether the technology can maintain its performance advantages while meeting the high-volume requirements of the global data center market.
