Frankfurt/Jenbach/Abu Dhabi, March 31, 2023 – Advent International (“Advent”) has reached an agreement with a wholly-owned subsidiary of the Abu Dhabi Investment Authority (“ADIA”), for ADIA to invest in and become a significant shareholder in Austrian energy solution provider INNIO. The consummation of the transaction is inter alia subject to customary regulatory approvals. 

Advent, one of the largest and most experienced global private equity investors with a well-established track record in the industrials sector, will continue to be the majority owner of the company. Following this transaction, Advent and ADIA, will partner to accelerate the company’s growth and support the company in further leading and empowering the transition to green energy.

Under Advent’s stewardship, INNIO has transformed from a leading provider of reciprocating engines for the conversion of gaseous input fuels to a green technology pioneer, delivering innovative energy solutions and services for the power generation, heating, cooling, and compression segments. The decentralized and flexible solutions range from various renewable energy sources, such as biogas and landfill gases, to 100 percent green hydrogen, building resilience for businesses and industries while reducing carbon intensity. INNIO’s iconic Jenbacher and Waukesha brands and the myPlant digital platform harness the power of engineering, technology, and green energy to accelerate a cleaner tomorrow.

We are looking forward to partnering with ADIA and to see them become a significant shareholder in INNIO. We will continue supporting INNIO in empowering the transition to clean energy while enabling the path to net zero. Under the ownership of Advent, INNIO has implemented a strong value creation plan that has already resulted in an improved performance of the business. With our partner ADIA, we will be able to provide INNIO with further resources to capitalize on the strong foundation that has been laid over the past few years to further drive the ongoing energy transition.

In addition, ADIA’s global and local expertise will allow us to further strengthen our business in the MENA region.
