SPAC Dynamix III files for a $150 million IPO, targeting energy and power industries

August 12, 2025

Dynamix III, a blank check company targeting the energy, power, and digital infrastructure industries, filed on Tuesday with the SEC to raise up to $150 million in an initial public offering.

The company plans to raise $150 million by offering 15 million units at $10. Each unit consists of one share of common stock and one-half of a warrant, exercisable at $11.50.

Dynamix III is led by CEO and Chair Andrea Bernatova, who previously served as CFO of resiliency microgrid company Enchanted Rock Energy and midstream water infrastructure company Goodnight Midstream. The SPAC plans to target companies operating in the energy, power, and digital infrastructure sectors, including technologies and services that reduce greenhouse gas emissions while supporting continued growth in global energy usage.

Management’s previous SPACs include Dynamix (DYNX; +17% from $10 offer price), which has a pending merger agreement with Ethereum treasury The Ether Machine, and ESGEN Acquisition, which completed its combination with residential solar provider Sunergy Renewables in 2024 to form Zeo Energy (ZEO; -76%).

The Houston, TX-based company was founded in 2025 and plans to list on the Nasdaq under the symbol DNMXU. Cohen & Company Securities is the sole bookrunner on the deal.
