ECI Partners has successfully exited its stake in CSL, a leader in critical IoT connectivity, achieving a 3.5 times return and signalling confidence in its ongoing expansion supported by a new continuation fund and innovative products like the rSIM.
ECI Partners has completed its exit from CSL, a leading company in critical IoT connectivity, successfully generating a 3.5 times return on its original investment. Since acquiring a stake in CSL in 2020, ECI reports that the firm has maintained an organic annual growth rate of approximately 20%, driven by strategic expansion into new geographical markets and diversification beyond its traditional sectors of building management, security, and telehealth.
CSL’s growth trajectory includes broadening its service provision across several additional verticals, such as transport and logistics, commercial property, retail, hospitality, and utilities. The company’s increasing prominence is exemplified by securing high-profile contracts, including its selection by Vodafone as the connectivity provider for the UK National Lottery, an endorsement of CSL’s critical and reliable connectivity solutions.
A notable product development during this period was the launch of the rSIM in 2024, a resilient and intelligent SIM card designed to optimise connectivity by actively monitoring network performance and switching profiles to maintain system uptime. This innovation aims to ensure operational continuity for mission-critical applications across a variety of industries. The rSIM technology was developed in close collaboration with Careium, an innovation leader in technology-enabled care. Their partnership, extending nearly 15 years, reflects a mutual commitment to delivering uninterrupted connectivity services critical to vulnerable populations. The rSIM’s patented ability to switch between two independent mobile operator profiles mitigates the risk of connectivity outages, providing a significant enhancement in service reliability, especially important in life-critical scenarios.
CSL’s CEO, Ed Heale, expressed pride in the company’s achievements under ECI’s stewardship, highlighting the successful launch of rSIM as a significant advancement in their product offering. He emphasised that CSL is well positioned as a market leader in critical connectivity across its served regions and industries, looking forward to continued growth and partnership with ECI.
This transaction marks ECI Partners’ first utilisation of a continuation fund, an investment vehicle allowing existing investors to reinvest in a business for an additional holding period. The fund is supported by prominent investors including Carlyle AlpInvest, HarbourVest Partners, and Pantheon, demonstrating ongoing confidence in CSL’s future prospects. Chris Watt, Managing Partner at ECI, noted CSL’s outstanding performance as a standout business in the IoT sector and affirmed ECI’s commitment to supporting its next phase of expansion.
ECI Partners has a strong track record in generating significant returns through strategic investments and exits, having achieved notable exits in 2022 with an average return above 4x and substantial internal rates of return. Such performance reinforces ECI’s expertise and credibility in scaling high-growth companies within the cloud, digital, and IoT spaces.
CSL itself has also expanded its capabilities through several strategic acquisitions, enhancing its product suite and geographic footprint. Its focus remains on providing high-reliability connectivity solutions across a range of critical sectors including telecare, fire and security, national infrastructure, retail, and utilities.
The advisory team for this transaction was led by Evercore as the financial advisor, with IA Global Capital providing additional financial advisory support. Legal counsel was provided by Paul, Weiss, Rifkind, Wharton & Garrison LLP, supplemented by further legal due diligence from Squire Patton Boggs LLP. OC&C handled commercial due diligence, while PwC conducted financial due diligence.
Overall, CSL’s evolution under ECI’s ownership, marked by strong growth, product innovation, and strategic expansion, illustrates the vitality and potential within the critical IoT connectivity sector. The company’s continued partnership with ECI through the continuation fund is poised to support further advancements and market leadership in this dynamic field.
