NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

To be held on June 5, 2026

TO THE STOCKHOLDERS:

Notice is hereby given that the 2026 annual meeting of stockholders (including any adjournments, postponements or continuations thereof, the “Annual Meeting”) of OneSpan Inc., a Delaware corporation, will be held on June 5, 2026 at 11:00 a.m. Eastern Daylight Time for the following purposes:

These items of business are more fully described in the proxy statement accompanying this Notice of Annual Meeting of Stockholders. We also will transact any other business that may properly come before the Annual Meeting, but we are not aware of any such additional matters.

As we have done for previous meetings, this year’s Annual Meeting will be held in a virtual meeting format only. You will not be able to attend the Annual Meeting in person.

You may register for and attend the webcast of the Annual Meeting via the Internet at www.virtualshareholdermeeting.com/OSPN2026 when you enter your 16-digit control number included with the Notice of Internet Availability or proxy card. Instructions on how to attend and participate in the Annual Meeting via the webcast are posted at www.virtualshareholdermeeting.com/OSPN2026. You will be able to vote your shares while attending the Annual Meeting by following the instructions on the website. You may revoke your proxy via the methods described in the accompanying proxy statement.

Our Board has fixed the close of business on April 8, 2026 as the record date for the determination of stockholders entitled to notice of and to vote at the Annual Meeting. Such stockholders are urged to vote, even if their shares were sold after such date.

YOUR VOTE IS VERY IMPORTANT. It is important that your voice be heard and your shares be represented at the Annual Meeting whether or not you are able to attend. We urge you to vote TODAY by completing, signing and dating the enclosed proxy card and promptly mailing it in the postage pre-paid envelope provided or following the instructions on the enclosed proxy card or Notice of Internet Availability to vote via the Internet or by telephone. Please submit a proxy as soon as possible, so that your shares can be voted at the Annual Meeting in accordance with your instructions. Please refer to “Questions and Answers Regarding Voting Procedures and Other Information” on page 4 of the accompanying proxy statement and the instructions on the proxy card or Notice of Internet Availability. Additionally, we hope that you can attend the Annual Meeting. If you are the beneficial owner of your shares (that is, you hold your shares in “street name” through an intermediary such as a broker, bank or other nominee), you will receive instructions from your broker, bank or other nominee as to how to vote your shares or submit a proxy to have your shares voted. We urge you to vote your shares for "ONE YEAR" for proposal 3 shown above and “FOR” each of the other proposals listed above.

By Order of the Board of Directors,

/s/ Victor Limongelli
