SES AI Soars 9.79% on Intelsat Acquisition

SES AI(SES)涨9.79%，连涨4天，近4日涨16.43%。，The share price rose to its highest level since April 2025 today, with an intraday gain of 11.22%.

The strategy of buying SES shares after they reach a recent high and selling them one week later resulted in a significant underperformance. Over the past five years, the strategy yielded a return of -35.14%, with a benchmark return of 58.03% and an excess return of -93.17%. The strategy's CAGR was -15.81%, indicating a clear decline in value. The Sharpe ratio was -0.13, suggesting poor risk-adjustled returns, while the maximum drawdown was 0.00%, which implies that the strategy avoided any further losses after the sell-off.

On July 17, 2025, the most significant factor driving the change in SES AI's stock price was the completion of SES's acquisition of Intelsat. This strategic move has resulted in the creation of a strengthened global satellite operator with an expanded fleet of 120 satellites across various orbits. This enhancement allows SES to deliver integrated multi-orbit, multi-band satellite and connectivity solutions to businesses and governments worldwide. The merger is anticipated to provide SES with a more robust financial foundation, including projected pro forma combined revenue growth and a substantial contract backlog. This acquisition positions SES as a stronger multi-orbit competitor, enabling it to better serve the evolving needs of its customers, thereby positively impacting its stock price.
