RMG ML Sports Holdings

Item 8.01. Other Events. As previously reported, on June 11, 2026, RMG ML Sports Holdings (the “Company”) consummated its initial public offering (“IPO”) of 20,000,000 units (the “Units”). Each Unit consists of one Class A ordinary share of the Company, par value $0.0001 per share (the “Ordinary Shares”), and one right to receive one-eighth (1/8) of one Ordinary Share (the “Rights”) upon the consummation of the Company’s initial business combination. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $200,000,000. The Company granted Santander US Capital Markets LLC, as representative of the several underwriters named on Schedule I thereto (the “Underwriter”), the right to purchase up to an additional 3,000,000 units to cover over-allotments, within 45 days of the closing (the “Over-Allotment Option”). Also as previously reported, on June 11, 2026, simultaneously with the closing of the IPO, the Company completed the private sale (the “Private Placement”) of an aggregate of 210,000 Units (the “Private Placement Units”) to RMG ML Sports Holdings Sponsor LLC (the “Sponsor”) at a purchase price of $10.00 per Private Placement Unit, generating gross proceeds to the Company of $2,100,000. A total of $200,000,000 of the proceeds from the IPO and Private Placement (which amount includes $6,000,000 of the underwriters’ deferred discount) was placed in a U.S.-based trust account maintained by Continental Stock Transfer & Trust Company, acting as trustee. An audited balance sheet as of June 11, 2026, reflecting receipt of the proceeds upon consummation of the IPO and the Private Placement, has been issued by the Company and is included as Exhibit 99.1 to this Current Report on Form 8-K. As previously disclosed, subsequently, on June 11, 2026, the Underwriter partially exercised the Over-Allotment Option for 1,650,000 Units. The closing of the issuance and sale of the additional Units (the “Over-Allotment Option Units”) occurred on June 15, 2026. The total aggregate issuance by the Company of 1,650,000 Over-Allotment Option Units at a price of $10.00 per unit generated total gross proceeds of $16,500,000. On June 15, 2026, an additional $16,500,000 consisting of the net proceeds from the sale of the Over-Allotment Option Units was placed in the trust account, resulting in a total of $216,500,000 held in the trust account. On June 16, 2026, the underwriters informed the Company that they would not exercise the remainder of the Over-Allotment Option. As a result, on June 16, 2026, 450,000 Class B ordinary shares of the Company were forfeited by the Sponsor. An unaudited pro forma balance sheet reflecting receipt of the proceeds from the sale of the Over-Allotment Option Units is included as Exhibit 99.2 to this Current Report on Form 8-K.
