EXPLANATORY NOTE

Diameter Credit Company (the “Company”, “we”, “us”, and “our”) is filing this Amendment No. 1 (the “Amendment”) to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the Securities and Exchange Commission (the “SEC”) on March 12, 2025 (the “Form 10-K”). The Company inadvertently omitted certain signatures from the signature page that was included with the Form 10-K. The Company is filing this Amendment solely to include the revised signature page.

In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), new certifications by the Company’s principal executive officers and principal financial officer are filed herewith as exhibits to this Amendment pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. As no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted. The Company is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) as no financial statements are being filed with this Amendment.

Except as described above, this Amendment does not modify or update disclosure in, or exhibits to, the Form 10-K. Furthermore, this Amendment does not change any previously reported financial results, nor does it reflect events occurring after the filing date of the Form 10-K. This Amendment should be read in conjunction with the Form 10-K.
