03/2026ECOLABCOOLIT SYSTEMSCANADAHardware & Electronics

KKR, alongside co-investor Mubadala Investment Company, has signed a definitive agreement to sell CoolIT Systems to Ecolab. This transaction marks a highly successful exit for KKR’s Global Impact Fund II, which acquired the company in 2023 for approximately $270 million. The strategic rationale for the deal is driven by the global "arms race" in AI infrastructure. CoolIT’s revenues surged by 300% during KKR’s ownership as its hyperscaler revenue share jumped from 5% to 60%, largely fueled by the shift to liquid-cooled GPUs (e.g., Nvidia). For Ecolab, the acquisition provides an immediate leadership position in the mission-critical cooling segment of the data center industry. A standout feature of the deal is KKR’s "broad-based ownership" program: all 650 employees were granted equity in 2023 and will receive cash payouts at closing ranging from one to over eight years of their annual salary. This exit is KKR’s first North American Global Impact payout and underscores the firm’s strategy of using employee ownership to drive industrial performance. CoolIT will continue to operate under its own brand, led by CEO Jason Waxman, as part of the broader Ecolab platform.

This structural alignment provides the organization with the scientific talent and technological hardware required to address the increasing demand for high-accuracy detection and the reduction of false alarms in complex environments.

02/2026INFINEON TECHNOLOGIESAMS-OSRAM (NON-OPTICAL SENSOR DIVISION)AUSTRIAHardware & Electronics

Infineon agreed to acquire the non-optical sensor business from AMS-Osram in a strategic carve-out. For AMS-Osram, this divestment marks a definitive pivot towards becoming a pure-play "Digital Photonics" leader, shedding non-core assets to focus entirely on optical semiconductors (LEDs, lasers, optical sensors). For Infineon, the acquisition strengthens its technological footprint in high-precision sensing without the burden of acquiring additional factories. The deal is structured as a "fabless" asset transfer: Infineon acquires the intellectual property, customer contracts, and R&D teams, but has signed a long-term supply agreement for AMS-Osram to continue manufacturing the wafers as a foundry service.

12/2025BPIFRANCE / MBDANANOXPLOREFRANCEHardware & Electronics

NanoXplore has successfully closed a €20 million fundraising round led by the European missile manufacturer MBDA and Bpifrance. This operation marks the company's first major institutional capital increase, aimed at accelerating its transition from a space-centric specialist to a diversified defense electronics powerhouse. The strategic rationale for the investors is twofold: securing a sovereign, ITAR-free supply of high-end FPGA components and supporting the company’s ambitious technological roadmap, which includes moving from 28-nanometer to 7-nanometer platforms in collaboration with the ESA and CNES. The funding will be utilized to expand NanoXplore's international footprint, particularly in Germany and Italy, and to potentially fund targeted acquisitions to consolidate the fragmented European microelectronics landscape. By bringing MBDA onto its cap table, NanoXplore gains a strategic anchor client and partner to co-develop next-generation electronic architectures for missiles, radars, and UAVs. This deal is a key component of the "France 2030" plan, reinforcing the continent's ability to produce critical semiconductors independently of American or Asian supply chains in an increasingly tense geopolitical climate.

12/2025WABTECFRAUSCHERAUSTRIAHardware & Electronics

Wabtec Corporation has finalized the acquisition of 100% of Frauscher Sensor Technology from the Delachaux Group and minority shareholder Michael Thiel. This exit marks a significant milestone for Delachaux, allowing the French family-owned group to refocus capital on its primary activities (Pandrol, Conductix-Wampfler, and DCX Chrome). The strategic rationale for Wabtec is the expansion of its Digital Intelligence portfolio through the addition of Frauscher’s world-class axle counting and signaling technologies. By combining Frauscher’s sensors with Wabtec’s analytics software, the group can provide a truly integrated safety-critical infrastructure offering. The acquisition is immediately accretive to Adjusted EBIT margins and EPS. Financially, the deal was structured to capitalize on Frauscher’s strong market position in India and Europe, providing a platform for accelerated profitable growth and significant cost synergies to be realized over a three-year period.
