CUSTOMER COMMUNICATION (ENGLISH AND SPANISH)

(For posting on website and mailing.)

To our Valued El Paso Electric Customers,

We want to share with you an important update about El Paso Electric (EPE). On June 3, 2019 we announced a significant, long-term investment in our service area. Infrastructure Investments Fund (IIF), an investment vehicle advised by J.P. Morgan Investment Management Inc., has agreed to acquire EPE. As we look to the future and the long-term investment needed to meet the growing energy needs of our communities, this is a major step in EPE’s ongoing commitment to providing safe, clean, affordable and reliable energy to you, our customers.

IIF is responsible for investing and growing the retirement funds of more than 40 million families, including 2 million people across Texas and New Mexico who will be invested in EPE. The IIF family of companies includes a number of other utilities. They are a leading investor in renewable energy and have a track record of delivering for the communities they partner with.

Let me assure you that now and in the future, we will continue providing you with safe and reliable service. We also are committed to communicating with our customers, employees and communities with transparency and respect.

EPE and IIF share the same vision for local job retention and growth, financially supporting our communities and creating a sustainable path to grow our renewable energy resources while protecting the environment.

EPE and IIF have agreed to a number of customer, employee and community commitments, which will take effect upon closing and include:

• Electric Bill Credit for Customers:EPE andIIF have committed to provide a credit on customer electric bills in the amount of $21 million over 36 months.

• Continuity of Local Workforce: IIF has made real commitments to ensure EPE’s workforce, including union and non-union employees and management, will remain in place.

• Community Contributions: EPE and IIF remain committed to $1.2 million in annual charitable contributions in our service area under the existing Community Partner Program, which provides employee engagement with and financial support to the many local organizations that positively impact the well-being of our communities.

• Community Economic Sustainability Fund: EPE andIIF commit to establishing a Community Economic Sustainability Fund to invest $100 million over 20 years to fund growth and economic development in our service area.

• Maintain Local Presence: EPE’s headquarters will remain in El Paso, Texas.

This agreement will better position EPE to meet the future energy needs of our service area. The partnership with IIF will enhance our ability to fulfill commitments to you - our customers - and the communities we serve, including investment in more renewable energy resources, local generation and other infrastructure needs.

Our agreement with IIF is subject to shareholder and regulatory approvals and other customary closing conditions. This process takes time, and we expect to complete the closing in the first half of 2020.

We will keep you informed as more information becomes available, and should you have any questions, please do not hesitate to reach out to Customer Service at (915) 543-5970 or (575) 526-5555. Our obligation and commitment remain the same - to provide safe, clean, affordable and reliable energy to our customers.
