PROXY STATEMENT SUPPLEMENT

2023 ANNUAL SHAREHOLDERS MEETING

This Proxy Statement Supplement (this “Supplement”), dated April 26, 2023, is being made available to shareholders of ServiceNow, Inc. (“ServiceNow” or the “Company”) on or about April 26, 2023, in connection with the solicitation of proxies by our Board of Directors (“Board”) for the Company’s 2023 Annual Shareholders Meeting to be held on Thursday, June 1, 2023 at 10:00 a.m. Pacific Time (the “Annual Meeting”). This Supplement, which adds to and amends the Proxy Statement, includes a new proposal to elect an additional director to the Board and an amended proxy card.

New Proposal No. 5 - Election of Additional Director. Proposal No. 5, which has been added to the agenda for the Annual Meeting, proposes the election of Deborah Black as a director, to serve until the next annual shareholders meeting and until her successor is elected and qualified or her earlier death, resignation or removal.

Amended Proxy Card. The enclosed amended proxy card (the “Amended Proxy Card”) differs from the proxy card previously furnished to you with the Proxy Statement (the “Original Proxy Card”), as the Amended Proxy Card includes new Proposal No. 5 for the election of Ms. Black as a director. If you have already voted, we encourage you to resubmit your vote on all five proposals by submitting the Amended Proxy Card by mail or by submitting a proxy by telephone or over the Internet by following the procedures on the Amended Proxy Card. If you vote by telephone or over the Internet, you do not need to return a proxy card by mail. However, if you return, or have already returned, an Original Proxy Card, then the votes indicated on such Original Proxy Card will remain valid for each of the proposals and director nominee elections other than Proposal No. 5 and will be voted at the Annual Meeting unless revoked. PLEASE NOTE THAT THE SUBMISSION OF A NEW PROXY CARD WILL REVOKE ALL PRIOR PROXY CARDS SUBMITTED, SO IT IS IMPORTANT TO INDICATE YOUR VOTE FOR EACH PROPOSAL ON THE NEW PROXY CARD, INCLUDING THOSE INCLUDED ON THE ORIGINAL PROXY CARD.

Except for the new Proposal No. 5 and the Amended Proxy Card, this Supplement does not modify, amend, supplement or otherwise affect any matter presented for consideration in the Proxy Statement.

PROPOSAL NO. 5

ELECTION OF DEBORAH BLACK AS A DIRECTOR

On April 25, 2023, the Board, acting upon the recommendation of the Nominating and Governance Committee, appointed Deborah Black to the Board as a director. The Board proposes that Ms. Black be re-elected at the 2023 Annual Meeting to serve for a one-year term expiring at the next annual shareholders meeting and until her successor is elected and qualified or until her earlier death, resignation or removal. Below is biographical and other information regarding Ms. Black.

Vice President, Head of Engineering of Netflix, Inc. DEBORAH BLACK INDEPENDENT DIRECTOR Deborah Black, age 63, has served on our Board since April 2023. Ms. Black has served as Vice President, Head of Engineering of Netflix, Inc., a media technology company, since August 2021. From October 2017 to July 2021, Ms. Black served as Vice President, eCommerce Services of Amazon.com, Inc., an electronic commerce and cloud-computing company. From 1992 to 2004, Ms. Black served in various roles at Microsoft Corporation, a global technology company, including as a Corporate Vice President within the Windows Division. Prior to joining Microsoft, Ms. Black was a distributed systems researcher at Bell Northern Research, a telecommunications research and development company. Ms. Black holds a Master of Science in Engineering degree in Computer Engineering and a B.S. degree in Computer Science from the University of Michigan. The Nominating and Governance Committee, with the assistance of an independent third-party search firm, has determined to recommend, and the Board to nominate, Ms. Black for election as a Director at the 2023 Annual Meeting. Our Board believes that Ms. Black’s extensive technology, product, business and management experience at large publicly-traded technology companies gives her the appropriate set of skills that qualify her to serve as a member of our Board.

Board Composition

The charts below show the collective composition of all of the director nominees, including Ms. Black, in terms of tenure, independence and diversity:

Additional information concerning the Board and the other director nominees identified in the Proxy Statement can be found in the sections titled “Board and Corporate Governance Matters” and “Director Compensation,” beginning on pages 7 and 27, respectively, of the Proxy Statement.

Vote Required and Recommendation of the Board

In an uncontested election of a director, a director nominee will be elected to our Board if the nominee receives more “FOR” votes than “AGAINST” votes. Broker non-votes and abstentions will have no effect on the outcome of the vote. Under our Corporate Governance Guidelines, when a director is elected or re-elected to the Board, he or she is required to submit a letter of resignation that will be effective only upon both (1) the failure to receive the required vote at any annual shareholders meeting at which the director faces re-election and (2) the acceptance of such resignation by our Board. If an incumbent director fails to receive the required vote for re-election, the Nominating and Governance Committee will decide whether to recommend that the Board accept the director’s irrevocable, conditional resignation and the Board will make the final decision.

OUR BOARD RECOMMENDS A VOTE “FOR” THE ELECTION OF

DEBORAH BLACK AS A DIRECTOR.

VOTING AND REVOCABILITY OF PROXIES

Please vote as soon as possible using the Amended Proxy Card enclosed with this Supplement, which includes new Proposal No. 5 —the election of Ms. Black as a director. If you already have voted, you are not required to vote again. If you would like to vote for the election of Ms. Black, however, you must vote again using the Amended Proxy Card.

If you return, or have already returned, an Original Proxy Card, then the votes indicated on such Original Proxy Card will remain valid for each of the proposals and director nominee elections other than Proposal No. 5 and will be voted at the Annual Meeting unless revoked. Please note that the submission of a new proxy card will revoke all prior proxy cards submitted, so it is important to indicate your vote for each proposal on any new proxy card, including those included on the Amended Proxy Card, the Original Proxy Card or any previously submitted proxy card.

If the Amended Proxy Card or Original Proxy Card is properly signed, dated and returned and is not revoked, the proxy will be voted at the Annual Meeting in accordance with your instructions indicated on the proxy card. If no instructions are given on how to vote your shares, your proxy will be voted in accordance with the Board’s recommendations on the proposals included on such proxy card.

You may revoke your proxy and change your vote at any time before your vote is due, including the final vote at the Annual Meeting if you have the right to vote at the Annual Meeting. Attendance at the Annual Meeting will not automatically revoke your proxy unless you vote at the Annual Meeting or specifically request in writing that your prior proxy be revoked.

Ms. Black has agreed to be named in this Supplement and to serve as a director, if elected. Our Board has no reason to believe that Ms. Black will be unavailable or will decline to serve as a director. In the event, however, that Ms. Black is unable or declines to serve as a director, following appropriate disclosure of the identity of a substitute candidate designated by our Board to fill the vacancy, the proxies given by way of the Amended Proxy Card will be voted for such substitute candidate.

OTHER MATTERS

The Board is not aware of any matters that are expected to come before the 2023 Annual Meeting other than those referred to in this Supplement and the Proxy Statement. As to any business that may arise and properly come before the Annual Meeting, however, the proxy holders will vote the proxies on these matters in accordance with their best judgment.
