Rice Acquisition Corp. II, which traded under the ticker RONI, was a blank-check company sponsored by Rice Acquisition Holdings II LLC and backed by the Rice family, known for their background in natural gas and energy transition investment. The SPAC completed its initial public offering in 2021 and targeted opportunities in the clean energy and power generation sector. In December 2022, RONI announced a definitive merger agreement with NET Power Inc., a developer of a natural gas power generation technology designed to produce zero atmospheric emissions using the Allam-Fetvedt Cycle. The 10-Q/A filed in March 2022 reflects an amendment to the SPAC's quarterly disclosure ahead of that announced combination. The de-SPAC transaction with NET Power closed in June 2023, bringing the company to the public markets.
