Item 5.07			Submission of Matters to a Vote of Security Holders.

On November 6, 2025, Synovus Financial Corp. (“Synovus”) held a special meeting of its shareholders (the “Special Meeting”) virtually via the Internet in connection with the proposed simultaneous mergers of Synovus and Pinnacle Financial Partners, Inc. (“Pinnacle”) with and into Steel Newco Inc., a newly formed Georgia corporation jointly owned by Synovus and Pinnacle (“Newco”, and such mergers, collectively, the “Merger”), pursuant to that certain Agreement and Plan of Merger, dated as of July 24, 2025, by and among Synovus, Pinnacle and Newco (as amended from time to time, the “Merger Agreement”) (as disclosed in the joint proxy statement/prospectus of Synovus and Pinnacle, filed with the U.S. Securities and Exchange Commission on September 30, 2025 (the “Joint Proxy Statement/Prospectus”), as supplemented by certain filings of Synovus prior to the date of the Special Meeting).

Of the 138,811,843 shares of common stock, par value $1.00 per share, of Synovus (“Synovus Common Stock”) issued and outstanding at the close of business as of September 26, 2025, the record date for the Meeting, a total of 105,722,435 shares of Synovus Common Stock were represented in person or by proxy, which represented 76.16% of the shares of Synovus Common Stock outstanding and entitled to vote at the Special Meeting, constituting a quorum to conduct business..

Following is an overview of the proposals that were submitted to the shareholders for approval at the Special Meeting (each of which proposals is described in greater detail in the Joint Proxy Statement/Prospectus) and a tabulation of the votes with respect to each proposal.

Proposal 1 – The Merger Proposal

The proposal to approve the Merger Agreement, pursuant to which, on the terms and subject to the conditions thereof, each of Pinnacle and Synovus will simultaneously merge with and into Newco, was approved by the votes set forth below:


Votes For	Votes Against	Abstentions	Broker Non-Votes
96,404,615	8,926,182	391,638	0

Proposal 2 – The Merger-Related Compensation Proposal

The proposal to approve, on an advisory (non-binding) basis, the Merger-related compensation payments that will or may be paid to Synovus’ named executive officers in connection with the Merger, was approved and received the votes set forth below:


Votes For	Votes Against	Abstentions	Broker Non-Votes
54,041,166	51,292,952	388,317	0

Approval of the Merger-Related Compensation Proposal is not a condition to completion of the Merger, and the vote with respect to such proposal was advisory only and will not be binding on Synovus.

Proposal 3 – The Adjournment Proposal

The proposal to approve the adjournment or postponement of the Special Meeting to a later date or time, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the Merger Proposal or to ensure that any supplement or amendment to the Joint Proxy Statement/Prospectus is timely provided to holders of Synovus Common Stock, was approved by the votes set forth below:


Votes For	Votes Against	Abstentions	Broker Non-Votes
99,966,056	5,218,420	537,959	0

Because there were sufficient votes to approve the Merger Proposal, no adjournment of the Special Meeting was determined to be necessary or appropriate, and accordingly, the Special Meeting was not adjourned and proceeded to conclusion.
