"I am deeply grateful for the trust, support, and partnerships I have experienced throughout my time with Elauwit. Together, we have accomplished remarkable things, and I believe that the organization is well-positioned for a bright and successful future."

"He has been a valued member of our leadership team and a good friend who departs having made a lasting and profound impact on our organization. We want to thank Rick for his tireless commitment and leadership and wish him unprecedented success in his future endeavors."

Under Alder's tenure, Elauwit reported significant progress across multiple performance metrics including:

	·	Expanded to 176 sites and nearly 40,000 units in 15 months while Elauwit was going public.

Item 5.07.

Submission of Matters to a Vote of Security Holders.

On June 18, 2026, at the annual meeting of stockholders (the "Annual Meeting") of Elauwit Connection, Inc. (the "Company"), the proposals set forth below were submitted to the Company's stockholders. The number of shares of common stock entitled to vote at the Annual Meeting was 6,619,796. The number of shares of common stock present or represented by proxy at the Annual Meeting was 5,459,880. The voting results for the proposals are as follows:

1.

The Company's stockholders elected three directors, each for a three-year term expiring in 2029 and until their successors have been duly elected and qualified. The number of shares that: (i) voted for the election of each such director; (ii) withheld authority to vote for each director; and (iii) represented broker non-votes with respect to each such director is summarized in the table below.

DIRECTOR NOMINEE		FOR		WITHHELD		BROKER NON-VOTES
Leslie Goodman		5,000,986		13,893		445,001
David O'Brien		5,014,838		41		445,001
Barry Rubens		5,013,979		900		445,001

Broker non-votes represent shares held by broker nominees for beneficial owners that were not voted because the broker nominee did not receive voting instructions from the beneficial owner and lacked discretionary authority to vote the shares on a non-routine proposal.

2.

The Company's stockholders ratified the selection of WithumSmith+Brown, PC ("Withum") as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. The number of shares that voted for, against and abstained from voting for the ratification of the selection of Withum as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026 is summarized in the table below.

FOR		AGAINST		ABSTAIN
5,458,962		918		0

3.

The Company's stockholders approved a proposal to adjourn the Annual Meeting from time to time, if necessary or appropriate, including to solicit additional votes in favor of Proposal One and/or Proposal Two (the "Non-Adjournment Proposals"), if there were not sufficient votes at the time of the Annual Meeting to adopt any of the Non-Adjournment Proposals or to establish a quorum. The number of shares that voted for, against and abstained from voting for this proposal is summarized in the table below.

FOR		AGAINST		ABSTAIN
5,444,747		15,133		0

Because the Non-Adjournment Proposals were approved by the Company's stockholders, an adjournment of the Annual Meeting was not necessary.
