Dear Fellow Shareholder:

By now you should have received your proxy materials in connection with the 2020 Annual Meeting of Shareholders (the “Annual Meeting”) of L3Harris Technologies, Inc. (“L3Harris”). As recently announced, our Board of Directors has changed the Annual Meeting from an in-person meeting to a virtual-only meeting via live audio webcast, though still to be held on Friday, April 24, 2020 at 9:30 a.m. Eastern Time, in response to current public health guidance regarding the coronavirus (COVID-19) pandemic and for the safety of participants.

It remains very important that your shares are represented and voted at the Annual Meeting, regardless of the number of shares you own or whether you are able to participate in the meeting webcast. If you have already voted, we thank you for taking the time to exercise your right to make your voice heard.

If you have not already voted, please take a moment to vote at your earliest convenience. You should carefully read and consider the information contained in the proxy statement, dated March 12, 2020, for the 2020 Annual Meeting of Shareholders of L3Harris (the “Proxy Statement”) to inform your vote.

For the reasons set forth in the Proxy Statement, our Board of Directors unanimously recommends that you vote:

FOR the election of the 12 nominees for director named in the Proxy Statement for a one-year term expiring at the 2021 Annual Meeting of Shareholders (Proposal 1),

FOR the approval, in an advisory vote, of the compensation of our named executive officers as disclosed in the Proxy Statement (Proposal 2),

FOR the ratification of our Audit Committee’s appointment of Ernst & Young LLP as our independent registered public accounting firm for our fiscal year 2020 (Proposal 3),

FOR an amendment of our Restated Certificate of Incorporation to eliminate the supermajority voting and “fair price” requirements for business combinations involving interested shareholders (Proposal 4),

FOR an amendment of our Restated Certificate of Incorporation to eliminate the “anti-greenmail” provision (Proposal 5),

FOR an amendment of our Restated Certificate of Incorporation to eliminate the cumulative voting provision that applies when we have a 40% shareholder (Proposal 6), and

AGAINST the shareholder proposal to permit the ability of shareholders to act by written consent, if such proposal is properly presented at the Annual Meeting (Proposal 7).

With the Annual Meeting fast approaching, we encourage you to vote promptly using any method available to you described in the enclosed proxy/voting instruction card. If you need assistance voting, or have any questions, please contact our proxy solicitor, Georgeson, toll-free at 1-888-613-9817.

Thank you, in advance, for your prompt attention to this very important matter.

Sincerely,

William M. Brown

Chairman and Chief Executive Officer
