How can I register and attend the Annual Meeting?

We have designed the virtual 2024 Annual Meeting to provide our shareholders substantially the same opportunities to participate as they would have at an in-person meeting. Our Annual Meeting will be completely virtual and conducted exclusively by a live audio webcast. You are entitled to participate in the Annual Meeting only if you were a shareholder of the Company as of the close of business on April 17, 2024, or if you hold a valid proxy for the Annual Meeting. No physical in-person meeting will be held.

You do not have to register in advance to attend the virtual meeting.

Whether or not you plan to attend the virtual annual meeting, we encourage you to vote and submit your proxy in advance of the meeting by one of the methods described under ''Voting and Other Information'' below. During the meeting, you may submit questions, vote, and examine our shareholder list.

The online meeting will begin promptly at 10:00 a.m. (Central Time) on June 12, 2024. We encourage shareholders to log in to the website and access the webcast early, beginning approximately 15 minutes before the Annual Meeting's 10:00 a.m. start time, to ensure you can hear the streaming audio before the Annual Meeting starts.

VOTING AND OTHER INFORMATION

Who Is Entitled to Vote?

April 17, 2024 is the record date for the Annual Meeting. If you owned shares of our common stock at the close of business on April 17, 2024, you are entitled to vote. As of April 17, 2024, we had 16,370,336 shares of common stock outstanding and entitled to vote at the Annual Meeting. Our common stock is our only class of voting stock.

How Many Votes Do I Have?

You have one vote for each share of our common stock that you owned at the close of business on April 17, 2024.

What Is the Difference Between Holding Shares as a Shareholder of Record and as a Beneficial Owner?

Many of our shareholders hold their shares through a broker or other nominee rather than directly in their own name. As summarized below, there are some differences between shares held of record and those owned beneficially.

Shareholder of Record

If your shares are registered directly in your name with our transfer agent, Computershare, you are considered, with respect to those shares, the shareholder of record and these proxy materials are being sent to you directly by Addus HomeCare. As the shareholder of record, you have the right to grant your voting proxy to the proxies listed on the proxy card or to vote in person online at the Annual Meeting. We have enclosed a proxy card for you to use.

Beneficial Owner

If your shares are held in a stock brokerage account or by another nominee, you are considered the beneficial owner of shares held in ''street name,'' and these proxy materials are being forwarded to you by your broker or other nominee who is considered, with respect to those shares, the shareholder of record. As the beneficial owner, you have

2

the right to direct your broker or nominee how to vote your shares and are also invited to attend the Annual Meeting. However, because you are not the shareholder of record, you may only vote these shares in person online at the Annual Meeting if you follow the instructions in the materials provided by your broker or other nominee, which may also allow you to use the internet or a toll free telephone number to vote your shares.

How Do I Vote by Proxy?

If you are a shareholder of record, you can vote by mailing in the enclosed proxy card or you can use one of the alternatives below:

• To vote by telephone: 1-800-690-6903
• To vote by internet: www.proxyvote.com

Please refer to the specific instructions set forth on the enclosed proxy card. In addition, please have the validation details, located on the proxy card, available when voting your shares. If you choose to vote your shares by telephone or through the internet, there is no need for you to mail back your proxy card.

If you hold your shares in street name, your broker or other nominee will provide you with materials and instructions for voting your shares, which may allow you to use the internet or a toll free telephone number to vote your shares.

May I Revoke My Proxy?

Yes. If you change your mind after you vote, you may revoke your proxy by following any of the procedures described below. To revoke your proxy:

• Send in another signed proxy with a later date;
• Send a letter revoking your proxy to Addus HomeCare's Secretary, Brian Poff, at 6303 Cowboys Way, Suite 600, Frisco, Texas 75034;
• Submit another vote by telephone or over the internet; or
• Attend the Annual Meeting and vote your shares in person online before your proxy is exercised at the Annual Meeting.

If you hold your shares in street name, your broker or other nominee will provide you with instructions on how to revoke your proxy.

How Do I Vote at the Annual Meeting?

To vote at the Annual Meeting, shareholders should log into www.virtualshareholdermeeting.com/ADUS2024 and follow the instructions provided on the website. If your shares are registered in your name, to vote you will need your 16-digit Control Number provided with your proxy card. If you are a beneficial owner (i.e., your shares are held in the name of your broker or bank), please refer to ''How can I register and attend the Annual Meeting?'' above for information on how to register to attend the Annual Meeting in order to vote your shares at the Annual Meeting.

What Votes Need to be Present to Hold the Annual Meeting?

To have a quorum for our Annual Meeting, persons must be present, in person online or by proxy, representing a majority of the votes that could be cast by the holders of all outstanding shares of stock entitled to vote at the meeting.

What Vote Is Required to Approve Each Proposal?

Election of Directors	A plurality voting standard applies to the election of each of the
	nominees for Class III director. Therefore, the three directors receiving
	the most ''For'' votes from the votes entitled to be cast by shareholders
	who are present in person online or represented by proxy at the Annual
	Meeting and entitled to vote on the election of directors will be elected.
Ratification of Appointment of	The ratification of the appointment of PricewaterhouseCoopers LLP as
Independent Auditor	independent auditor for the fiscal year ending December 31, 2024
	requires the affirmative vote of a majority of the votes entitled to be cast
	by shareholders who are present in person online or represented by
	proxy at the Annual Meeting and entitled to vote.
Advisory Vote on Named	The approval, on an advisory, non-binding basis, of the Company's
Executive Officer Compensation	compensation of its named executive officers requires the affirmative
	vote of a majority of the votes entitled to be cast by shareholders who
	are present in person online or represented by proxy at the Annual
	Meeting of Shareholders and entitled to vote.

How Are Votes Counted?

In the election of Addus HomeCare's directors, your vote may be cast ''FOR'' the nominee or your vote may be ''WITHHOLD'' with respect to the nominee. For the ratification of Addus HomeCare's independent auditor and the advisory vote on named executive officer compensation, your vote may be cast ''FOR'' or ''AGAINST'' or you may ''ABSTAIN.''

How Would My Shares Be Voted if I Do Not Specify How They Should Be Voted?

If you sign your proxy card with no further instructions, your shares will be voted in accordance with the recommendations of the Board. We will appoint one or more inspectors of election to count votes cast at the meeting or by proxy.

As noted above, if your shares are held in a stock brokerage account or by another nominee, your broker or nominee will provide you with materials and instructions for you to use in directing your broker or nominee as to how to vote your shares. New York Stock Exchange (''NYSE'') Rule 452 provides that brokers and other nominees may not exercise their voting discretion on specified non-routine matters without receiving instructions from the beneficial owner of the shares. Because Rule 452 applies specifically to securities brokers, virtually all of whom are governed by NYSE rules, Rule 452 applies to all companies listed on a national stock exchange, including companies (such as the Company) listed on the Nasdaq stock market (the ''Nasdaq'').

We expect that the ratification of the appointment of PricewaterhouseCoopers LLP as the Company's independent auditor for the fiscal year ending December 31, 2024 (Proposal 2) to be the only proposal that is considered a ''routine'' matter. Accordingly, if your shares are held through a broker or other nominee, that person will have discretion to vote your shares on Proposal 2 if you fail to provide instructions. On the other hand, the election of Class III directors (Proposal 1) and the approval of named executive officer compensation (Proposal 3) will be considered ''non-routine'' matters. Thus, if you do not give your broker or other nominee specific instructions on how to vote your shares with respect to Proposals 1 and 3, your broker or other nominee will inform the inspector of election that it does not have the authority to vote on that matter with respect to your shares. This is generally referred to as a ''broker non-vote.'' A broker non-vote may also occur if your broker or other nominee fails to vote your shares for any reason. Therefore, if you hold your shares through a broker or other nominee, please instruct that person regarding how to vote your shares on at least Proposal 1 and Proposal 3.

What Is the Effect of Broker Non-Votes, Abstentions and Withhold Votes?

With respect to Proposal 1, you may vote ''FOR'' or ''WITHHOLD'' for each director nominee. A vote to withhold or a broker non-vote will not affect the outcome of the election, because each director nominee is elected by plurality. With respect to Proposals 2 and 3, abstentions have the same effect as negative votes because, in order
