Sun Life Financial reported a fourth-quarter adjusted earnings per share (EPS) of C$1.68, falling short of the C$1.79 estimate. The company's profit for the quarter was C$237 million, a decline of C$512 million compared to the previous year. The earnings miss was attributed to weakness in the U.S. business and challenges in the group-health protection sector. Following the disappointing results, Sun Life's shares experienced a significant drop, marking their worst day since the onset of the pandemic.
