Dear Sirs,

Re: Liberty Latin America Ltd. (the “Company”)

We have acted as special Bermuda legal counsel to the Company in connection with a registration statement on form S-1 (Registration No. 333-221608) filed with the U.S. Securities and Exchange Commission (the “Commission”) on 8 December, 2017 (the “Registration Statement”, which term does not include any other document or agreement whether or not specifically referred to therein or attached as an exhibit or schedule thereto) relating to the registration under the U.S. Securities Act of 1933, as amended, (the “Securities Act”) to register the distribution of 48,428,867 Class A common shares, par value US$0.01 each (the “Class A Shares”), 1,940,193 Class B common shares, par value US$0.01 each (the “Class B Shares”) and 120,843,663 Class C common shares, par value US$0.01 each (the “Class C Shares”, and, together with the Class A Shares and the Class B Shares, the “Common Shares”) in connection with the Split-Off (as defined below). The Registration Statement also registers up to an additional 3,124,174 Class A common shares, par value US$0.01 each and 7,070,717 Class C common shares, par value US$0.01 each that may be distributed in the Split-Off (the “Additional Company Shares”) to holders of LiLAC Class A Ordinary Shares and LiLAC Class C Ordinary Shares (collectively, the “ LGP Plan Shares”) issued after 6 December 2017 upon the exercise or settlement of options, share appreciation rights and restricted share units prior to the completion of the Split-Off in accordance with the terms of the Liberty Global 2014 Incentive Plan Effective March 1, 2014 as amended and restated February 24, 2015 (the “2014 Employee Plan”), the Liberty Global 2014 Nonemployee Director Incentive Plan Effective March 1, 2014 (the “2014 Nonemployee Plan”), the Liberty Global, Inc. 2005 Incentive Plan (as amended and restated effective

June 7, 2013) (the “2005 Incentive Plan”), the Liberty Global, Inc. 2005 Nonemployee Director Incentive Plan (as amended and restated effective June 7, 2013) (the “2005 Nonemployee Incentive Plan”) and/or the Virgin Media 2010 Stock Incentive Plan (as amended and restated effective June 7, 2013) (the “Virgin Incentive Plan” and together with the 2014 Employee Plan, the 2014 Nonemployee Plan, the 2005 Incentive Plan and the 2005 Nonemployee Incentive Plan, the “Plans”) as the case may be.

For the purposes of giving this opinion, we have examined a copy of the Registration Statement. We have also reviewed the memorandum of association and the bye-laws of the Company, each certified by the Secretary of the Company on 8 December, 2017, minutes of a meeting of the Company’s board of directors held on 8 December, 2017, and written resolutions of the Company’s sole shareholder dated 8 December, 2017 (together, the “Resolutions”) and such other documents and made such enquiries as to questions of law as we have deemed necessary in order to render the opinion set forth below.

For the purpose of our opinion in paragraph 2 below, we have reviewed and relied upon a copy of the register of members of Liberty Global plc (“LGP”) dated 6 December 2017 prepared by Computershare Trust Company, N.A. the registrar and transfer agent for LGP (the “Register of Members”). The Common Shares will be distributed on a one-for-one basis: (i) in the case of the Class A Shares, in respect of the issued LiLAC Class A Ordinary Shares of LGP; (ii) in the case of the Class B Shares, in respect of the issued LiLAC Class B Ordinary Shares of LGP; (iii) in the case of the Class C Shares, in respect of the issued LiLAC Class C Ordinary Shares of LGP, in each case on the basis of the number of the relevant class of LiLAC Ordinary Shares in issue on the record date, following the contribution of the LiLAC Group (as defined in the Registration Statement) by LGP to the Company as described under the caption “The Split-Off” in the prospectus forming a part of the Registration Statement (the “Split-Off”).

We have assumed (a) the genuineness and authenticity of all signatures and the conformity to the originals of all copies (whether or not certified) examined by us and the authenticity and completeness of the originals from which such copies were taken, (b) that where a document has been examined by us in draft form, it will be or has been executed and/or filed in the form of that draft, and where a number of drafts of a document have been examined by us all changes thereto have been marked or otherwise drawn to our attention, (c) the accuracy and completeness of all factual representations made in the Registration Statement, the Plans and other documents reviewed by us, (d) that the Resolutions were passed at one or more duly convened, constituted and quorate meetings, or by unanimous written resolutions, remain in full force and effect and have not been rescinded or amended, (e) that there is no provision of the law of any jurisdiction, other than Bermuda, which would have any implication in relation to the opinions expressed herein, and (f) that, upon the issue of any Additional Company Shares or Common Shares, the Company will either receive consideration for the issue price thereof which shall be equal to at least the par value thereof or shall have sufficient amounts available for distribution to pay up at least the par

value of any Additional Company Shares or Common Shares and allot such Additional Company Shares or Common Shares as fully paid bonus shares.

We have made no investigation of and express no opinion in relation to the laws of any jurisdiction other than Bermuda. This opinion is to be governed by and construed in accordance with the laws of Bermuda and is limited to and is given on the basis of the current law and practice in Bermuda. This opinion is issued solely for the purposes of the filing of the Registration Statement, the distribution of the Common Shares by the Company and the registration of the Additional Company Shares, and is not to be relied upon in respect of any other matter.

On the basis of and subject to the foregoing, we are of the opinion that:

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the references to our firm under the captions “Legal Matters” in the prospectus forming a part of the Registration Statement. In giving this consent, we do not hereby admit that we are experts within the meaning of Section 11 of the Securities Act or that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the Rules and Regulations of the Commission promulgated thereunder.
