Energy and environment investment banking: fundraising, IPO and M&A

Landfill gas to biomethane, solar assets, industrial wastewater treatment: Apparius advises companies bringing energy transition and environmental technologies to industrial scale.

These business models combine proprietary technology with industrial assets, and their financing needs change in scale as the company grows. We advised Waga Energy from its Series B through to its IPO on Euronext, and advised on sales to industry players such as Indaver and Cap Vert Énergie.

Deeptech 2019 – 2021

From Waga Energy's €10M round to its IPO

Apparius supported Waga Energy over a substantial part of its financial journey. In 2019, we helped the company secure a €10 million round from investors including ALIAD, Ovive, Starquest, Noria and Tertium, financing its international expansion and the development of its WAGABOX® technology.

We then advised the founders on the company’s €126 million initial public offering on Euronext Paris in October 2021. The IPO gave Waga Energy the capital to accelerate its expansion and establish itself as a European leader in producing biomethane from landfill gas.
