As previously reported, on December 16, 2024, Roman DBDR Acquisition Corp. II (the “Company”) consummated its initial public offering (“IPO”) of 20,000,000 units (the “Units”). Each Unit consisted of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Ordinary Shares”), and one-half of one redeemable warrant of the Company (each, a “Warrant”), with each whole Warrant entitling the holder thereof to purchase one Class A Ordinary Share for $11.50 per share. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $200,000,000. The Company also granted the underwriters a 45-day option to purchase up to an additional 3,000,000 units (“Over-allotment Units”) at the initial public offering price to cover any over-allotments.

On January 23, 2025, the underwriters exercised the over-allotment option in full, and on January 27, 2025, purchased an additional 3,000,000 Over-allotment Units pursuant to the full exercise of the over-allotment option. The Over-allotment Units were sold at an offering price of $10.00 per share, generating gross proceeds to the Company of $30,000,000. In connection with the closing of the over-allotment option, the Company’s sponsor and B. Riley Securities, Inc., the representative of the IPO underwriters, purchased an additional 750,000 private placement warrants in the aggregate at a price of $1.00 per warrant, generating total gross proceeds of $750,000. Following the closing of the over-allotment option and the sale of additional private placement warrants, an aggregate amount of $30,150,000 was deposited into the Company’s trust account established in connection with the IPO.

On January 28, 2025, the Company issued a press release announcing the closing of the full exercise of the over-allotment option. A copy of the press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference herein.
