Vote your OGE shares

The Annual Meeting of Shareholders of OGE Energy Corp. will be held virtually via the internet at 10 a.m. CDT, Thursday, May 21, 2020. Details on how to access the meeting are included in the proxy materials made available to each shareholder.

Members are encouraged to vote their shares prior to the annual meeting by the applicable deadline for voting. This deadline varies by a few days depending on where the shares are held. For members that hold shares in the OGE Energy Corp. Retirement Savings Plan (401(k)), administered by Fidelity Investments, the deadline for voting prior to the annual meeting is Monday, May 18. For shares held in a brokerage firm or other type of account, the deadline may be earlier or later. For example, for shares held by Fidelity brokerage accounts, the deadline for voting, prior to the annual meeting, is Wednesday, May 20. As explained below, voting during the annual meeting is also available.

The items for this year’s annual meeting include:

1.Elect 10 members of the board of directors
2.Ratify the appointment of Ernst & Young LLP as the company's principal independent accountants for 2020
3.Hold an advisory vote to approve named executive officer compensation
4.Amendment of the restated certificate of incorporation to eliminate supermajority voting provisions
5.Shareholder proposal regarding allowing shareholders to act by written consent
6.Attend to any other business properly presented at this meeting

The board of directors recommends a vote to elect 10 members of the board of directors in proposal (1); FOR proposal (2); FOR proposal (3); FOR proposal (4); and AGAINST proposal (5).

Most company members are shareholders through benefit plans like the Retirement Savings Plan (401(k)), and therefore as shareholders are entitled to vote. Company members make up an important percentage of OGE ownership, so it's important to vote your shares prior to the meeting by the applicable deadline set out above. Active members who own OGE shares through the Retirement Savings Plan will receive a proxy card via U.S. Mail with instructions for voting, by one of three methods:

Telephone: 1-800-690-6903
Mail: Return the proxy card in the postage paid envelope

When voting on the internet or by telephone before the meeting, you will need your 16-digit control number, which is printed on the proxy card (received by mail). You may also enter an email address to receive a confirmation when your vote is recorded. Internet and telephone voting are available until 11:59 p.m. Eastern time on the applicable deadline for voting prior to the meeting.

As noted in the Company’s Proxy Statement, due to COVID-19 and the Company’s desire to protect the health and well-being of our shareholders, Board and management, this year’s annual meeting is being held virtually rather than as an in-person meeting. During this virtual annual meeting, voting will also be available online at a specially designated webcast during the annual meeting May 21. To vote online during the meeting, shareholders will need to follow the instructions at

Each shareholder has a unique 16-digit control number that is provided with the proxy voting instructions and will need to have this number available when accessing the virtual meeting webpage.

Electronic voting and website posting of financial reports and proxy information help the company save costs in printing, mailing and handling expenses. Every member who participates in the electronic voting process, by internet or telephone, contributes to the savings.

Preliminary results of the shareholder proxy voting will be announced during the annual meeting and immediately to members via Breaking News. Final voting results will be filed with the SEC within four business days of the meeting.
