What is Enterprise Value (EV)?

Enterprise Value (EV) is a measure of a company's total value, often used as a more comprehensive alternative to equity market capitalization. EV includes in its calculation the market capitalization of a company but also short-term and long-term debt as well as any cash on the company's balance sheet.

The EV/EBITDA multiple is a financial ratio that compares a company's Enterprise Value (EV) to its Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA).

SOSTELIA GROUP acquired by HERA GROUP

ITALY Utilities (Regulated Infrastructure) / Water EV 100M - 350M EUR

Context

Hera Group's acquisition of Sostelia represents a strategic move to consolidate its leadership in Italy's environmental services sector, with a specific focus on industrial and civil water treatment. The transaction creates a national benchmark player with a fully integrated service offering, spanning from plant design and construction to operation, maintenance, and the ultimate disposal of liquid waste and purification sludge. A primary driver for the deal is the significant potential for commercial and operational synergies with Herambiente, Hera's environmental services subsidiary. The integration is expected to broaden Herambiente's commercial portfolio by adding Sostelia’s specialized services, such as plant revamping and maintenance for private industrial clients. Conversely, Sostelia's extensive customer base presents a valuable new market for Herambiente's established waste management solutions. The acquisition also combines the deep technical know-how of both entities, enhancing their collective capabilities to address increasingly stringent environmental regulations, such as new EU directives on wastewater treatment, and tackle challenges like water scarcity and pollutant abatement. By integrating Sostelia’s expertise, plant infrastructure, and commercial reach, Hera Group aims to diversify its revenue streams, expand its customer base, and bolster its business resilience in a market that demands continuous innovation and high-quality service.

SOSTELIA GROUP, which reported an EBITDA margin of LOGIN in 2025, is valued in this transaction at an EV/EBITDA multiple of LOGIN.
