 and have found it also reduces costs. The format is particularly useful when practical limitations on in-personinteraction limit shareholder engagement and participation. If you are the record holder of your shares, you may attend the meeting by registering at the following website: www.proxydocs.com/ADPT. To participate in the Annual Meeting, you will need the control number included on the Notice of Internet Availability of Proxy Materials, your proxy card or the instructions that accompanied your proxy materials. We refer to attending the meeting through this website as attendance “via Internet,” and it is considered the same as attendance in person for all corporate purposes. If your shares are held in “street name,” in the name of a broker, trustee or other nominee, you may change your vote by submitting new voting instructions to your broker, trustee or other nominee, or, if you have obtained a legal proxy from your broker or other nominee giving you the right to vote your shares, by attending the meeting and voting via the Internet. Broker Non-Votes Brokers or other nominees who hold shares of common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. 3

However, brokers are not allowed to exercise their voting discretion with respect to the election of directors or for the approval of other matters that are considered “non-routine” matters without specific voting instructions from the beneficial owner. These non-voted shares are referred to as “broker non-votes.” If your broker holds your common stock in “street name,” your broker will vote your shares on “non-routine” proposals only if you provide instructions on how to vote by filling out the voter instruction form sent to you by your broker with this proxy statement.

Only Proposal No. 3 (ratifying the appointment of our independent registered public accounting firm) is considered a routine matter. Proposals No. 1 (election of director) and No. 2 (Say-on-Pay) are not considered routine matters, and without your instruction, your broker cannot vote your shares for those proposals.

Quorum and Votes Required

The inspector of elections will also determine whether a quorum is present. In order to constitute a quorum for the conduct of business at the Annual Meeting, a majority of the votes entitled to be cast must be represented in person (via Internet) or by proxy
