The launch of Nuvei's card issuing service is likely to be seen as a positive development by investors, as it represents an expansion of the company's product offerings and potential for new revenue streams. The service's benefits such as improved working capital efficiency and increased customer loyalty are likely to attract new clients and retain existing ones, which could lead to increased usage of Nuvei's platform and higher transaction volumes. The planned expansion into additional markets like the UK, US, and Latin America in 2024 indicates future growth potential. However, the actual impact on the stock will depend on the market's perception of the service's success and the company's ability to execute its roll-out plan effectively.
