Overview

StoneCalibre is an international private investment firm founded in 2012, with offices in Los Angeles and Paris. According to its official website, the firm focuses on corporate divestitures, buy-and-builds and special situations opportunities via control transactions. It describes itself as a generalist investor with relevant expertise in Healthcare, Technology, Industrials and Business Services. To date, StoneCalibre states it has acquired 70 companies throughout North America and Europe through 7 different investment platforms. The firm's stated approach centers on three transaction types: corporate divestitures (non-core, non-strategic assets, complex carve-outs, product line divestitures, regulatory-driven sale processes and timing considerations with post-closing partnerships), buy-and-builds (platforms in fragmented industries, organic and inorganic growth, international consolidation, vertical or horizontal expansion and integrations), and special situations (operational turnaround, legacy products, declining revenue, secular decline, financial restructuring and storied credits). StoneCalibre emphasizes a patient long-term capital base, focused on buying and building businesses over the long term without the external pressure to exit investments at a pre-defined time period. It also highlights flexible deal structuring, having completed numerous carve-outs from Fortune 500 companies, and an extensive execution history across entrepreneur-owned companies, public-to-private transactions and corporate divestitures. One of its investment platforms, Calibre Scientific, has been active in the life sciences tools and laboratory supply sector. In November 2023, Calibre Scientific acquired Scientific Support Services Ltd, a UK-based provider of scientific instruments, supplies and services to customers in the petrochemical, environmental, pharmaceutical, clinical, and food and flavors sectors. In January 2024, Calibre Scientific acquired Labtech International Ltd, a UK-based provider of life science instruments, products and services to customers in the biotechnology, diagnostics, education, environmental and pharmaceutical sectors across the UK and Ireland. These acquisitions illustrate StoneCalibre's buy-and-build strategy in the life sciences distribution and services space. StoneCalibre operates as a private investment firm and is not publicly listed. Its portfolio spans multiple industries, and its website lists current and exited investments, including a Business Services acquisition from June 10, 2013 that has since been exited.
