Rodino was one of four directors appointed by Codere Newco and had served as co-chief executive of the business since it merged with special purpose acquisition company DD3 Acquisition Corp II in November last year.
He was also chief strategy and corporate affairs officer for the business.
Upon completing the merger, Codere Online, which spun off of the wider Codere Group, became the first Latin America-facing online gambling operator to go public.
Rodino will be replaced by Borja Fernández, pending formal appointment by shareholders at the next general shareholder meeting.
Fernández has worked as a director across multiple boards and different sectors for over 17 years, while he has also spent time in private equity, structured finance and capital markets, including as a chief financial officer.
He is currently managing partner for Ahorro Corporación Financiera in Spain, where he leads the business’s private equity and corporate investment banking (CIB) practices.
The resignation and subsequent hire come after Codere Online last month said significant growth in Mexico helped it achieve acceleration in net gaming revenue during the second quarter of 2022.
The group posted total revenue of €27.4m during the three months to 30 June 2022, which was up 36% on Q2 2021.
