From the Desk of Curt Morgan

December 1, 2017

Greetings,

Since we announced our merger agreement about a month ago, Vistra and Dynegy leaders have been working diligently to map out the necessary steps for a successful transition and integration of two great companies. We held a two-day kickoff this week in Irving, and we are off to a great start. I have also decided on my direct reports and the head of our retail business, who will also be members of the management committee of the combined company. That structure and the respective functional areas are detailed below.

At the kickoff, I reminded leaders of a key near-term deliverable: to be prepared to close the transaction by early March and integrate the two companies within six months following close. We want to be prepared internally, so that as soon as we receive all final regulatory approvals and all necessary closing conditions are satisfied, we can close quickly on the transaction. Just as important as our preparation to close is our need to detail and assign accountability for delivering on the synergy and operational improvement targets we committed that the combined company would achieve after closing when the deal was announced.

I was able to meet many Dynegy employees earlier this month. Jim Burke, Sara Graziano, and I spent a couple of days in the Houston office and spoke with a number of people at two town halls. I appreciated the excellent questions and feedback; these meetings gave me a chance to hear the issues that are important to the people who work there. We have additional visits planned to Houston and Collinsville in the next two weeks, and we are working on the schedule to get members of the management committee to other sites over the next several weeks. As I have mentioned at our town halls in Irving and Houston, we are committed to creating the leading integrated power company from the abundance of talent at both companies and making and communicating organization decisions as quickly as possible.

My direct reports, who along with me will be charged to lead the new Vistra following close, and their high-level responsibilities are listed below. I have made some adjustments to the management committee makeup and responsibilities which will allow these leaders and their groups to focus on our expanded business footprint and asset base following closing. Reporting to me will be:

 

    Sano Blocker, senior vice president of government affairs with responsibility for federal affairs; state affairs; and public policy.

 

    Jim Burke, executive vice president and chief operating officer with responsibility for retail; nuclear operations; fossil operations; environmental, health, and safety; plant support; supply chain; and decommissioning.

 

    Amanda Frazier, vice president of regulatory policy with responsibility for all regulatory affairs and policy and environmental policy.

 

    Sara Graziano, senior vice president of corporate development and strategy with responsibility for mergers and acquisitions; analytics and structuring; development and emerging technology; and corporate venture capital.

 

    Bill Holden, executive vice president and chief financial officer with responsibility for controller; planning; treasury; tax; risk; internal audit; and investor relations.


    Carrie Kirby, executive vice president and chief administrative officer with responsibility for HR operations; field HR; corporate affairs; facilities and real estate; and corporate security.

 

    Ravi Malick, senior vice president and chief information officer with responsibility for enterprise, generation, and retail systems; architecture and governance; infrastructure; cyber security; applications; vendor management; and strategic programs.

 

    Stephanie Zapata Moore, executive vice president and general counsel with responsibility for compliance and the corporate secretary’s office; litigation; labor and employment; regulatory; and legal business support.

 

    Steve Muscato, senior vice president and chief commercial officer with responsibility for regional power desks (ERCOT, PJM, New York/New England, MISO, CAISO); origination and pricing; gas supply and optimization; fuels, and financial trading.

In addition to my direct reports, Scott Hudson will continue as senior vice president and president of the retail business, reporting to Jim Burke.

In closing, we have implemented a communication plan with the goal of keeping people at both companies updated with any news or developments. We have also provided multiple ways for employees at both companies to ask questions. I want to thank you for your dedication and focus on safety, on our customers, and on the important task of preparing for the high-demand winter season. I also ask for your patience as we build out the new Vistra organization. We are creating the leading integrated power company with excellent assets, an enviable balance sheet, and most important of all, great people.

Curt Morgan

President and Chief Executive Officer
