To Stockholders of 10x Genomics, Inc.:

Our 2026 Annual Meeting of Stockholders (“2026 Annual Meeting”) will be held on Thursday, June 4, 2026 at 11:30 a.m. PDT.

You will be able to attend the meeting, submit your questions online during the meeting and vote your shares electronically at the meeting by visiting https://edge.media-server.com/mmc/p/e4koppar.

The attached notice and proxy statement describe the formal business to be transacted at the meeting.

Whether or not you attend the virtual 2026 Annual Meeting, it is important that your shares be represented and voted at the meeting. Therefore, I urge you to vote promptly and submit your proxy via regular mail, online or by telephone. The 2026 Annual Meeting is being held so that stockholders may consider:

Proposal One: the election of the Class I directors listed in the accompanying proxy statement, each to serve a three-year term expiring at the 2029 annual meeting of stockholders or until such director's successor is duly elected and qualified or until such director's earlier death, resignation, disqualification or removal;

The board of directors recommends that you vote FOR the election of the nominees named in Proposal One of the accompanying proxy statement and FOR each of Proposals Two and Three.
