On August 27, 2024, SilverBox Corp III (the “Company”) filed an amendment to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware (the “Charter Amendment”). The Charter Amendment provides for (i) the option to extend the date by which the Company must effect its initial business combination from the Termination Date up to six (6) times for an additional (1) month each time to March 2, 2025 (each, an “Extension”) upon the deposit into the Trust Account of the Monthly Extension Payment (as defined below) for each Extension, (ii) the conversion of the shares of Class B common stock into shares of Class A common stock at the option of the holder(s), and (iii) the elimination of the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Securities Exchange Act of 1934 of less than $5,000,000.

The foregoing description is qualified in its entirety by reference to the Charter Amendment, a copy of which is attached as Exhibit 3.1 hereto and is incorporated by reference herein.

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

On August 27, 2024, the Company held a special meeting of stockholders (the “Special Meeting”) to approve the Extension Amendment Proposal, the Conversion Amendment Proposal, the Redemption Limitation Amendment Proposal and the Adjournment Proposal (collectively, the “Proposals”), each as more fully described in the Company’s definitive proxy statement, filed with Securities and Exchange Commission (the “Commission”) on August 7, 2024. A total of 14,903,320 of the Company’s Class A common stock and Class B common stock (the “Common Stock”) or 86.4% of the Company’s outstanding shares of Common Stock as of August 5, 2024, the record date for the Special Meeting, were represented virtually or by proxy at the Special Meeting.

The final voting results for the Proposals were as follows:

Proposal No. 1: The Extension Amendment Proposal. To amend the Company’s Amended and Restated Certificate of Incorporation by allowing the Company to extend the date by which it has to consummate a business combination from September 2, 2024 (the “Termination Date”) to March 2, 2025, comprised of six (6) one-month extensions (each, an “Extension”) for a total of six months following the Termination Date (assuming the Business Combination has not occurred) (the end date of each such Extension, the “Extended Date”), as determined by the Company’s board of directors (the “Board”), if requested by the Sponsor upon notice to the Board on the day immediately preceding the applicable Extended Date, by depositing the Monthly Extension Payment into the Trust Account. To effectuate each Extension, the Sponsor and/or its designee(s) will deposit the lesser of (i) $100,000 and (ii) $0.025 for each share of Class A common stock then outstanding after giving effect to redemptions (the “Monthly Extension Payment”).

Proposal No. 2 The Conversion Amendment Proposal. To amend the Company’s Amended and Restated Certificate of Incorporation to provide for the right of holders of shares of the Company’s Class B common stock, par value $0.0001 per share, to convert such shares into shares of the Company’s Class A common stock, on a one-for-one basis at any time and from time to time at the election of the holder.

FOR				AGAINST				ABSTAIN
	13,634,243				1,269,077				0

Proposal 3: Redemption Limitation Amendment Proposal. To amend the Company’s Amended and Restated Certificate of Incorporation to eliminate from the limitation that the Company may not redeem public shares to the extent that such redemption would result in the Company having net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Securities Exchange Act of 1934 of less than $5,000,000 (the “Redemption Limitation”) in order to allow the Company to redeem public shares irrespective of whether such redemption would exceed the Redemption Limitation.

FOR				AGAINST				ABSTAIN
	13,634,246				1,269,074				0

Proposal No. 4: The Adjournment Proposal. The Company had solicited proxies in favor of an Adjournment Proposal which would have given the Company authority to adjourn the Meeting to solicit additional proxies. As sufficient shares were voted in favor of the other Proposals, this proposal was not voted upon at the Meeting.

Stockholders holding 10,019,700 shares of the Company’s Class A common stock (“Public Shares”) exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $107 million will be removed from the Trust Account to pay such holders. Following redemptions, the Company will have 3,780,300 Public Shares outstanding.

Item 8.01       Other Events.

On August 28, 2024, the Sponsor converted all of its 3,450,000 shares of Class B common stock into 3,450,000 shares of Class A common stock.
