Dear IBM Senior Leaders:<br>Re: Voting Your IBM Shares for the 2026 Annual Meeting<br>I am writing to remind you to make sure to vote all of your IBM shares for the 2026 Annual Meeting. By now you should have received a copy of IBM's 2026 Proxy Statement along with the proxy card or Notice of Internet Availability of Proxy Materials. If you hold IBM shares in "street name" (i.e., through a bank or broker), you will have received a voter instruction form from your bank or broker. Some of you will receive multiple copies of the proxy materials, reflecting different ownership accounts you may have. Please make sure to vote all of the proxy voting cards that you receive or follow the instructions on the Notice of Internet Availability of Proxy Materials, if applicable.<br>As you know, IBM's strategy continues to fuel growth, drive innovation, and deliver strong results. Throughout 2025, we continued to execute against our strategy and delivered $67.5 billion in revenue. We generated cash from operations of $13.2 billion, and returned $6.3 billion to our stockholders through our dividend, which we increased for the 30th consecutive year. In 2026, your Company is well-positioned for continued success and to deliver growth and greater value to stockholders.<br>As you see in the Proxy Statement, the Board recommends a vote:

&nbsp;&nbsp;&nbsp;&nbsp;• <u>FOR</u> Item of Business 1: Election of our Directors

&nbsp;&nbsp;&nbsp;&nbsp;• <u>FOR</u> Item of Business 2: Ratification of Appointment of our Independent Registered Accounting Firm

&nbsp;&nbsp;&nbsp;&nbsp;• <u>FOR</u> Item of Business 3: Say on Pay Proposal

&nbsp;&nbsp;&nbsp;&nbsp;• <u>FOR</u> Item of Business 4: 2026 Long-Term Performance Plan Proposal

&nbsp;&nbsp;&nbsp;&nbsp;• <u>AGAINST</u> Item of Business 5: Stockholder Proposal Requesting a Change to IBM's Outside Director Stock Ownership Guidelines

&nbsp;&nbsp;&nbsp;&nbsp;• <u>AGAINST</u> Item of Business 6: Stockholder Proposal Requesting a Right to Act by Written Consent

&nbsp;&nbsp;&nbsp;&nbsp;• <u>AGAINST</u> Item of Business 7: Stockholder Proposal Requesting a Report on AI Bias

&nbsp;&nbsp;&nbsp;&nbsp;• <u>AGAINST</u> Item of Business 8: Stockholder Proposal Requesting a Report on Discrimination in Charitable Support

<br>For the reasons explained in our Proxy Statement, we believe that such votes are in the best interests of our Company and its stockholders. It is important that you show your support for IBM and vote your shares. If you hold your shares in record name (i.e., directly through our transfer agent, Computershare) and need assistance regarding your record accounts, please contact Bob Wilt at infoibm@us.ibm.com. If you hold your shares in street name (e.g., Morgan Stanley, Merrill Lynch, Charles Schwab, or another financial institution), you will need to contact your broker directly in order to obtain a replacement voting instruction form.

You may also find additional information at http://www.ibm.com/investor/proxyinformation. If you do not receive a copy of the Proxy Statement or Notice of Internet Availability of Proxy Materials by Tuesday, April 14, 2026, please contact Bob Wilt at infoibm@us.ibm.com. If you have already voted all of your shares, no further action is required on your part. Please do not hesitate to call me at 914-499-xxxx or email me at xxxxxxxx@us.ibm.com if you have questions or comments.<br>Sincerely,<br>

/s/ Jane P. Edwards

Jane P. Edwards<br>Vice President and Secretary
