Recommendation

While Rigetti reported increased operational losses and declining revenue in Q2 2025, which are negative short-term indicators, the company successfully completed a substantial $350 million equity raise. This capital infusion significantly strengthens its balance sheet, providing a long runway for continued research and development in the capital-intensive quantum computing sector. Furthermore, the announcement of the general availability of the Cepheus-1-36Q, with improved performance metrics and a clear roadmap for a 100+ qubit system by year-end, demonstrates strong technological progress. For a seasoned investor, the operational losses are expected for a pre-profit, high-growth technology company. The key takeaway is the successful capital raise, which de-risks the company's ability to execute its ambitious technology roadmap. Therefore, a 'hold' recommendation is appropriate, acknowledging the ongoing operational challenges but emphasizing the strengthened financial position and promising technological advancements that support long-term potential in a high-risk, high-reward industry.
