Debra Reed

The first in her family to graduate from college, Reed became the $11-billion-in-sales energy services company’s first female CEO in 2011. Now she’s pushing to ­expand, planning to invest more than $19 billion over the next five years in utilities and infra­structure in the U.S., Mexico, and South America. Despite the volatility in the industry, Sempra’s stock has risen 80% during Reed’s tenure.
