Dear Sirs

DPC Holdings Limited (the "Company") - Registration of Securities under the US Securities Act of 1933, as amended (the "Securities Act")

Background

1.1

We have acted as the Company's Jersey legal advisers in connection with the registration statement on Form S-1 dated June 18 2026 filed with the United States Securities and Exchange Commission (the "Registration Statement") related to the initial public offering (the "IPO") and the proposed registration under the Securities Act by the Company of 23,333,333 ordinary shares of no par value in the capital of the Company (the "Shares"), and 3,499,999 additional Shares to cover the underwriters' option to purchase additional Shares, if any.

1.2

The Company has asked us to provide this Opinion in connection with the registration of the Shares under the Securities Act.

1.3

In this Opinion, "non-assessable" means, in relation to a share in the share capital of the Company, that the purchase price for which the Company agreed to issue and sell that share has been paid in full to the Company, so that no further sum is payable to the Company or its creditors by any holder of that share solely because of being the holder of such share.

1.4

Pursuant to the Underwriting Agreement, the Shares will be sold to the underwriters through the facilities of the Depositary Trust Company for the respective accounts of the underwriters.
