Overview

Atena Equity Partners is a Portuguese private equity firm based in Lisbon. Founded in 2014, it describes itself as an "operational investor" (Investidores Operacionais), combining in-house operational experience with control equity and debt investments. The firm targets Portuguese companies with ambitious plans for succession, sector consolidation or restructuring, and adapts each transaction structure to the needs of the seller and the company in which it invests. Since its creation in 2014, Atena has invested essentially in three areas of activity: industry, healthcare and business services. According to its website, the combined businesses in its portfolio represent sales volume of more than €300 million, more than half of which is international, reaching more than 40 countries and employing more than 2,500 people. The firm raised its first fund in 2014 and continues to invest through its funds. Atena positions itself as a long-term investor with a focus on ESG throughout the investment lifecycle, arguing that this focus allows it to mitigate risks and identify value-creation opportunities. Its stated culture is built on independence, directness (frontalidade) and merit. The firm's team was founded on the premise that possessing operational experience in-house is critical to making better investment decisions and to helping the management teams of portfolio companies design truly transformational projects. A notable transaction was the acquisition of the Malo clinics in May 2019. In July 2019, Atena announced a €4 million investment in the Malo Clinic alongside an agreement with banks to reduce liabilities, the closure of some consulting offices, and a strategic plan for the business. The firm continues to operate as a private, independent private equity investor in Portugal.
