What HT5 does

Centiel, the operating company now trading on SIX Swiss Exchange under ticker CNTL following its April 2026 reverse merger with shell company HT5 AG, designs and manufactures three-phase uninterruptible power supply (UPS) systems for mission-critical applications. Its core technology is modular UPS architecture, anchored by the proprietary DARA platform that eliminates single points of failure, with the STRATUSPOWER family supporting configurations up to 1,125 MW for AI data centers, and the standalone PREMIUMTOWER family serving healthcare. Additional product lines include CUMULUSPOWER three-phase and single-phase UPS systems, ESSENTIALPOWER single-phase units, LIFEPOWER energy storage, and UPS network management software. The company traces its technical lineage to early transformer-less UPS designs and the early development of three-phase modular UPS systems, with a lean organizational structure positioned for fast product iteration.

Centiel generates revenue primarily through direct enterprise B2B sales of UPS hardware under quote-based pricing tied to power capacity and configuration complexity, with multi-year service contracts layering in 24/7/365 support revenue. The customer base is concentrated in four mission-critical verticals: AI and colocation data centers (the primary segment), hospitals and healthcare, banks and financial services, and intelligent mobility and transportation, with named reference customers including CERN, hospital systems, and major data center operators. The company operates in more than 60 countries and employs between 251 and 500 people. In FY2025 it reported consolidated revenue of approximately CHF 46 million (over 25% year-on-year growth, on a 30% three-year CAGR), net profit of CHF 8 million, and an expected EBIT margin of approximately 22%, with a post-listing market capitalization reaching approximately CHF 310 million following the CHF 31.4 million capital increase organized by UBS.
