Overview
AmberStone Group is a Latvian private investment group that has been active since 2013. According to its own disclosures, it has gathered 94 shareholders from 13 countries who have entrusted it with EUR 65 million. The group describes its mission as combining a smart and results-driven investment strategy with a love for work, the country and its people, and it positions itself as a hands-on owner that actively participates in the management and strategic decision-making of its portfolio companies. AmberStone Group invests through several channels: equity stakes in companies (with participation of no less than 25%), loans to companies whose shareholder is AmberStone Group, and publicly traded shares and debt securities. Its investment approach is based on backing strong professionals and businesses with the potential to compete, and then engaging energetically in governance rather than remaining a passive financial investor. The group's portfolio spans a number of sectors of the Latvian economy. Its website highlights healthcare, where it aims to provide world-class services at competitive prices; hospitality, where it argues that hotel and restaurant quality is a national calling card; agriculture, where it sees innovation becoming increasingly important; construction, which it views as a major contributor to national economic growth; wood processing, where it stresses the need for greater added value; and renewable energy, where it seeks to reduce air pollution and dependence on fossil fuels. In 2023 AmberStone Group reported consolidated profit of EUR 3.5 million, a return on equity (ROE) of 5%, and an equity ratio of 78% of total assets. The group has also been consolidating its hospitality business under a single brand, Keystone Collection, and its construction arm Pillar Contractor has carried out large-scale energy-efficiency improvement and historic interior restoration works, including at the Opera. AmberStone Group is a private company and is not listed on a stock exchange. It operates primarily in Latvia and the wider Baltic region, and its stated values are care, knowledge and a long-term commitment to the development of the companies and sectors in which it invests.

The group's stated philosophy is that every euro has three tasks: to grow shareholder capital, to promote the development of the company, and to serve as a positive impulse for the entire sector. When all three are fulfilled, the group moves on to the next challenges. The group invests in private equity, providing growth financing and managing companies, as well as in securities. Its investment criteria focus on strong professionals and the potential to compete.
