### 보쉬 매각 (주거·경상업 HVAC 사업부) (high)
- note: Sold the R&LC HVAC business (including the Hitachi JV) to Bosch in July 2025 — $8.1B total, JCI's share $6.7B, ~$5.0B after-tax net cash. Bosch's largest-ever acquisition, and the turning point that reshaped JCI into a commercial-buildings/datacenter pure-play and funded buybacks/investment.

### JCH (존슨컨트롤스 60%·히타치 40% 공조 합작, 2025 보쉬 매각으로 청산) (high)
- note: The global residential air-conditioning JV (JCH) in which JCI held 60% and Hitachi 40% — it was JCI's residential HVAC arm, but was divested to Bosch in July 2025 together with the R&LC HVAC business. The key piece shed in the pivot to a pure-play commercial/datacenter company.

### 데이터센터 냉각 M&A (Silent-Aire·Accelsius) (high)
- note: The forward bets that built today's liquid-cooling stack — acquiring hyperscale modular-cooling firm Silent-Aire for $755M in 2021 and investing in 2-phase direct-to-chip (D2C) specialist Accelsius in 2022. Seeds planted before the AI boom, now harvested in a record backlog.
- [mentions] Johnson Controls (EN, ir, published 2025-09-08) https://www.johnsoncontrols.com/media-center/news/press-releases/2025/09/08/johnson-controls-expands-thermal-management-offering-with-scalable-liquid-cooling-solution-to-meet-t: "Silent-Aire CDUs and Accelsius 2-phase D2C anchor JCI's datacenter-cooling portfolio."

### 부품·원자재 (컴프레서·제어 전자·냉매·철강·구리) (mid)
- note: The cost base of chiller/CDU/fire/controls hardware — it procures compressors, control electronics, refrigerants and commodities like steel and copper. Because the backlog is largely fixed-price, input-cost inflation is a structural squeeze on near-term margins.
- [mentions] SEC EDGAR (EN, filing, published 2025-11-14) https://www.sec.gov/Archives/edgar/data/833444/000083344425000097/jci-20250930.htm: "The fixed-price backlog is exposed to pricing risk from raw-material and component cost inflation."

### 마이크로소프트 (Azure — OpenBlue 디지털 플랫폼) (mid)  → /microsoft.md
- note: JCI's 'digital brain,' OpenBlue, runs on Microsoft Azure — a co-development partnership using Azure Data Lake, Time Series, AI/ML and Azure OpenAI to power generative-AI building agents. JCI sells building outcomes but rents the cloud/AI compute beneath them from Microsoft, so its software margin and AI features ride Azure.
- [confirms] Memoori (EN, analysis, published 2026-01-15) https://memoori.com/johnson-controls-ai-strategy-smart-buildings/: "OpenBlue is a co-development partnership on Microsoft Azure — per-customer data segregation, using Azure Data Lake, Time Series and AI/ML."
- [confirms] Johnson Controls (EN, news, published 2024-11-12) https://www.johnsoncontrols.com/media-center/news/press-releases/2024/11/12/johnson-controls-expands-ai-features-in-openblue: "JCI expanded generative-AI agents in OpenBlue — data kept within the Azure cloud."
