Graf Global Corp. Announces NYSE American Ticker Symbol Change to

"TONT" (3-on-3) in Anticipation of Closing of Business Combination with Big3 Basketball

THE WOODLANDS, Texas, July 16, 2026 (BUSINESS WIRE) - Graf Global Corp. (the "Company") (NYSE American: GRAF) today announced that it will change the ticker symbols for its Class A ordinary shares trading on NYSE American from "GRAF" to "TONT". The Company's units and warrants, now trading on NYSE American as GRAF U and GRAF WS, respectively, also will be changed contemporaneously to "TONT U" and "TONT WS", respectively. These ticker symbol changes are expected to take effect at the opening of trading on Monday, July 27, 2026.

The change to the new ticker symbol "TONT" reflects the Company's previously announced proposed business combination with Big3 HoldCo LLC ("BIG3"), recognized as the world's premier professional 3-on-3 basketball league, founded by O'Shea Jackson, Sr. (Ice Cube) and Jeff Kwatinetz, and the announced future trading symbols after closing. "TONT" stands for "3-on-3."

Holders of "TONT" shares and "TONT WS" warrants will own common equity and warrants of the surviving BIG3 entity on a 1:1 basis upon the closing of the business combination expected in the fourth quarter of 2026, subject to the satisfaction or waiver of all conditions to closing, when the public trading entity will be named Big3 Basketball Holdings, Inc. After closing of the business combination and the approval of the combined company's application to list its securities on a national securities exchange, BIG3 shares and warrants will continue to trade as "TONT" and TONT WS" respectively, and the "TONT U" units will be split into one "TONT" share and ½ "TONT WS" warrant.

The Company is a blank check company and has no material assets other than approximately $92 million in cash deposits and no other business operations other than completing the announced business combination with BIG3. Investors in "GRAF" now and "TONT" after July 27, 2026 are effectively buying equivalent interests in BIG3 when the business combination closes.

"In the run-up to the closing of our business combination with BIG3 and our excitement for BIG3 fans to participate in the growth of the league, we thought it was important to begin to brand and market our public securities as they will trade post-closing. There will be a clear automatic transition to ownership of BIG3 securities after closing," said James Graf, Chief Executive Officer of the Company. "BIG3 management and I have received calls from fans and other investors wanting to know when they can buy the "TONT" shares referenced in our transaction announcement. The answer is now, with "GRAF" becoming "TONT" on July 27, which will become the BIG3 entity upon the closing of the business combination."

The closing of the business combination is subject to several conditions including the filing and effectiveness of an S-4 registration statement with the Securities and Exchange Commission, approval by the Company's shareholders, the Company's delivery of no less than $50 million in net cash proceeds to BIG3, and approval of the combined company's application to list its securities on a national securities exchange, among other conditions, as more fully described in the business combination agreement filed with the SEC on June 12, 2026.

Buyers of the Company's public shares, whether under "GRAF" now or "TONT" after July 27, 2026, will retain the right, at their discretion, to redeem those shares for cash in connection with the business combination at a redemption price equal to the per share amount held in the Company's trust account, or they can hold their shares through closing and own the surviving BIG3 shares. Further information about your redemption rights will be set forth in the S-4 registration statement to be filed by the parties in connection with the business combination. All public shareholders have such redemption rights and are free to trade their shares before or after the ticker symbol change. As of July 16, 2026, the cash value per share available for redemptions was approximately $10.86, which amount is expected to continue to accrue interest until the redemption date to be set in connection with the business combination closing.

No action is required by existing shareholders in connection with the ticker symbol changes. The Company's Class A ordinary shares, units and warrants will continue to be listed on NYSE American as "GRAF", "GRAF U" and "GRAF WS" until the ticker symbols change to "TONT", "TONT U" and "TONT WS" respectively, on July 27, 2026, and the CUSIP numbers for the securities will remain unchanged.
