Mr. Johan Cieza De
Los Santos
Legal Representative
MSRA S.A.C
Av. Almirante Miguel Grau Nº 629 Urb. San
Ignacio, Barranco, Lima
Ref.: File Nº 2026017300
I am writing to you regarding the following:
(i) Valuation Report submitted by MSRA
S.A.C. (hereinafter, MSRA), which determined the minimum price to be taken into account by Holcim Ltd. in the Public Tender Offer (OPA)
for the common shares representing the share capital of Cementos Pacasmayo S.A.A. (hereinafter, Pacasmayo), submitted on October 14, 2026
(hereinafter, Valuation Report).
(ii) Official Letter Nº 5332-2026-SMV/11.1
dated October 21, 2026 (hereinafter, Official Letter Nº 5332), issued by the General Intendency of Conduct Supervision.
(iii) Brief submitted by MSRA on October
22, 2026, in response to Official Letter Nº 5332, through which it addressed the observations contained in said official letter.
In this regard, following the review of the brief
dated October 22, 2026, it has been noted that MSRA has not sufficiently addressed certain observations. Accordingly, pursuant to the
provisions of Article 51 and Annex V of the Regulations on Public Tender Offers and the Purchase of Securities by Delisting, approved
by CONASEV Resolution Nº 009-2006-EF/94.10 and its amendments, the following observations are required and reiterated:
Regarding requirement 2.2 of Official Letter Nº
5332: While it was noted that private investment is the variable with an official projection most closely linked to cement demand, you
have not substantiated why Pacasmayo’s sales volume should grow at the growth rate of private investment. Therefore, you must complete
your response.
Regarding requirement 2.9 of Official Letter Nº
5332: Concerning the “Model’s 2036 D&A”, while you indicated the amounts of depreciation of property, plant, and equipment
and the amortization of intangibles that comprise it, you did not attach the tables displaying the calculations and respective supporting
documentation; therefore, the requirement is reiterated on this point.
Regarding requirement 3.1 of Official Letter Nº
5332: While the line items included under the accounts “Inventories”, “Land”, and “Other property, plant, and
equipment, net” were detailed—as well as the factors applied to each of said line items along with a brief description—you
have not substantiated how the percentages indicated for each item were obtained. Therefore, you are required to complete your response
by submitting the calculations performed to reach each of the factors for the line items included under the accounts “Inventories”
and “Other property, plant, and equipment, net”.
This requirement must be addressed within a maximum
period of one (01) business day, counted from the business day following notification of this official letter.
Without further business, I remain yours faithfully.
Sincerely,
César Figueroa Benites
Acting General Intendant General Intendency of
Conduct Supervision
