Alphabet Inc.

1. Why am I receiving these materials?

Our Board made these materials available to you online, or, upon your request, has delivered printed proxy materials to you, in connection with the solicitation of proxies for use at Alphabet’s 2026 Annual Meeting of Shareholders (Annual Meeting), which will take place on Friday, June 5, 2026 at 9:00 a.m., Pacific Time, via our virtual meeting site atwww.virtualshareholdermeeting.com/GOOGL26. You are invited to participate in and vote on the items of business described in this proxy statement at the Annual Meeting if you were a holder of Alphabet Class A or Class B common stock as of the close of business on April 6, 2026, the Record Date for the Annual Meeting, or hold a valid proxy for the Annual Meeting. This proxy statement includes information that we are required to provide to you under the SEC rules and that is designed to assist you in voting your shares.

2. What is included in the proxy materials?

The proxy materials include:

•this proxy statement;

•our 2025 Annual Report to Shareholders, which includes our Annual Report on Form 10-K for the fiscal year ended December 31, 2025; and

•the proxy card or a voting instruction form for the Annual Meeting.

3. What information is contained in this proxy statement?

The information in this proxy statement relates to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our directors and certain of our executive officers, corporate governance, and certain other required information.

4. Why did I receive a notice in the mail regarding the internet availability of proxy materials instead of a full set of proxy materials?

In accordance with rules adopted by the SEC, we may furnish proxy materials, including this proxy statement and our Annual Report, to our shareholders by providing access to such documents online instead of

mailing printed copies. Most shareholders will not receive printed copies of the proxy materials unless they request them. Instead, the Notice of Internet Availability of Proxy Materials (Notice), which was mailed to the holders of Class A and Class B common stock, will instruct you as to how you may access and review all of the proxy materials online. The Notice also instructs you as to how you may submit your proxy online. If you would like to receive a paper or email copy of our proxy materials, you should follow the instructions for requesting such materials in the Notice.

5. I share an address with another shareholder and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice and, if applicable, the proxy materials to multiple shareholders who share the same address unless we receive contrary instructions from one or more of the shareholders. This procedure reduces our printing costs, mailing costs, and fees. Shareholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written request, we will deliver promptly a separate copy of the Notice and, if applicable, the proxy materials to any shareholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy of the Notice and, if applicable, the proxy materials, shareholders may contact us as follows:

Alphabet Inc.Attn: Investor Relations1600 Amphitheatre ParkwayMountain View, California 94043

Email:investor-relations@abc.xyz

Number:(650) 253-3393

Shareholders who hold shares in street name (as described on page 101) may contact their brokerage firm, bank, broker-dealer, or other similar organization to request information about householding.

If you are eligible for householding, but you and other shareholders of record with whom you share an address currently receive multiple copies of the proxy materials, or if you hold stock in more than one account, and in either case you wish to receive only a single copy of the proxy materials for your household, please contact us using one of the aforementioned methods.

6. How can I access the proxy materials online?

The Notice, proxy card, or voting instruction form will contain instructions on how to:

•view our proxy materials for the Annual Meeting online and vote your shares; and

•instruct us to send our future proxy materials to you electronically by email.

Our proxy materials are also available on our Investor Relations website athttps://abc.xyz/investor/annual-meeting/.

Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you, and will reduce the impact of printing and mailing these materials on the environment. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you revoke it.
