Dear Fellow Employee,

Today we took an important step toward our transition to a fully regulated utility company with the announcement that prominent investors are making a $2.5 billion equity investment in our company.

This investment will enable us to reduce FirstEnergy holding company debt by $1.45 billion and accelerate our growth and infrastructure improvement plans for our transmission and distribution business. These actions will benefit our shareholders and our six million customers.

Importantly for employees, this investment further strengthens our pension plan, since FirstEnergy will contribute $750 million of the proceeds to the pension. Earlier this month, the company contributed $500 million to the pension. With the additional $750 million from this transaction, we will not need to make further contributions to the pension in 2018, 2019 and 2020.

Although we have made good progress toward our goal of transforming our company into a regulated utility, we know we have more work to do. To that end, we have formed what we’re calling a restructuring working group to serve in an advisory role on our strategy to exit the competitive generation business.

The restructuring working group will include Jim Pearson, executive vice president and chief financial officer; Leila Vespoli, executive vice president of corporate strategy, regulatory affairs and chief legal officer; and Gary Benz, senior vice president of strategy; as well as two outside members.

It’s important to note that the FirstEnergy Solutions’ (FES) Board of Directors will continue to make decisions about our competitive subsidiary, including any related to filing for bankruptcy protection for FES.

Today’s announcement demonstrates that we have a sound strategy to transform our company into a high-performing, fully regulated utility. Thank you for your good work and continued support.

Chuck Jones

Additional details about this transaction are included in the news release and Letter to the Investment Community that the company issued today, as well as answers to questions you may have.
