Oficial Letter 2152-2026-SMV/11.1

Dear sirs,

CEMENTOS PACASMAYO S.A.A. (the “Company”), with Single Taxpayer Registry (RUC) No. 20419387658, with domicile for these purposes at Calle La Colonia No. 150, district of Santiago de Surco, province and department of Lima, duly represented by Mr. Diego Roda Lynch, identified with DNI No. 09753981, in his capacity as Stock Market Representative, respectfully states:

On May 12, 2026, the Company was notified of Official Letter No. 2152-2026-SMV/11.1 (the “Official Letter 2152”), through which the General Superintendence of Conduct Supervision (the “Superintendence”) of the Securities Market Superintendence (SMV) requested certain information and documents from us related to the valuation of the Company’s shares. This is within the framework of the mandatory public tender offer for the common shares of the Company that Holcim Ltd. must launch in accordance with the Regulations for Public Tender Offers and Purchase of Securities by Exclusion, approved by CONASEV Resolution No. 00009-2006 (the “OPA”).

Likewise, in response to the request made by the Company on May 14, 2026, on May 15, 2026, the Company was notified of Official Letter No. 2330-2026-SMV/11.1, through which the Superintendence granted us an extension of three (3) additional business days beyond the deadline established in Official Letter 2152 to respond to the requirements formulated in said letter.

We refer to the previous material events published by the Company (including those dated March 30, 2026, April 6, 2026, and May 14, 2026), in which the Company has noted that, as a consequence of the indirect acquisition of a significant stake of 50.01% in Pacasmayo’s shareholding by Holcim Ltd. (through the acquisition of shares issued by Inversiones ASPI S.A. (the “Transaction”)), Holcim Ltd.’s obligation to formulate the OPA has been generated.

Telf: 317-6000

Accordingly, within the period granted to address the points expressed in the referred Official Letter, we proceed to answer each of the aspects mentioned therein, in the order in which they have been included:

Report, as a sworn declaration and under the scope of Article 12, literal c), of the TUO of the LMV, the agreements, side letters, shareholder agreements, or any other additional agreement to the SPA of December 16, 2025, that may have been signed between Holcim or its shareholders, with Mr. Eduardo Hochschild Beeck, Inversiones ASPI, CEMPACASMAYO, or its directors and/or managers, or any third party that has participated directly or indirectly in the structuring, negotiation, or execution of the Transaction, that contemplate economic benefits, compensations, assumption of liabilities, or deferred payments in favor of the selling shareholder, which should be considered in the context of the future OPA.

Through a communication dated May 21, 2026, attached to this communication, Holcim has informed us, as a sworn declaration, that it has not signed any agreement, side letter, shareholder agreement, or any other agreement additional to the SPA of December 16, 2025.

Likewise, Pacasmayo informs, as a sworn declaration, that it has not signed with Holcim or with any third party that has participated directly or indirectly in the structuring, negotiation, or execution of the Transaction, any agreements, side letters, shareholder agreements, or additional agreements that contemplate economic benefits, compensations, assumption of liabilities, or deferred payments in favor of the selling shareholder, which should be considered in the context of the future OPA

Indicate if there were clauses in the SPA and/or in any additional or complementary document related to burdens or obligations imposed on CEMPACASMAYO as a condition for the execution or closing of the Transaction

Conforme ha sido confirmado por Holcim Ltd., en el SPA no existen obligaciones impuestas a la Sociedad, sino que se establecieron obligaciones de cargo de los vendedores bajo dicho contrato, en virtud de las cuales ellos debían causar que las Compañías Transferidas - entre las que se encuentra la Sociedad- realice (o se abstenga de realizar) determinadas acciones, siendo la más relevante aquella establecida en el numeral 6.01 del SPA, la cual indica lo siguiente¹:

As confirmed by Holcim Ltd., there are no obligations imposed on the Company in the SPA; rather, obligations were established for the sellers under said contract, by virtue of which they had to cause the Transferred Companies—among which is the Company—to perform (or refrain from performing) certain actions. The most relevant is established in Section 6.01 of the SPA, which indicates the following

Section 6.01 Conduct of Business Prior to Closing. From the signing date of the SPA until closing, unless (i) expressly provided otherwise in the SPA, (ii) established in Section 6.01 of the Annexes to the SPA, (iii) consented to in writing by Holcim, in its capacity as buyer (consent which shall not be unreasonably withheld, conditioned, or delayed), or (iv) required to comply with applicable legislation, the Sellers shall, and shall cause CPAC and other subsidiaries of Inversiones Aspi S.A. to: (a) use commercially reasonable efforts to conduct their activities in the ordinary course of business, in accordance with past practices in all material respects; and (b) use commercially reasonable efforts to (1) maintain and preserve intact its current organization, business, and franchise of CPAC and other subsidiaries of Inversiones Aspi S.A. and (2) preserve intact its rights, franchises, goodwill, and relationships with customers, lenders, suppliers, distributors, lessors, governmental authorities, and other persons with whom they maintain business relationships.

According to the information provided by Holcim, within this type of SPA clauses, there are also those referring—with respect to CPAC and its subsidiaries—to Holcim Ltd.’s right to access certain information (Section 6.02 of the SPA), the obligation to maintain civil liability insurance policies in favor of directors and executives (Section 6.04 (b) of the SPA), and obtaining third-party consents due to change of control clauses and the treatment of certain debt (Sections 6.08 and 6.19 (a) of the SPA).

Inform if, in the last three (03) years, your represented company, Inversiones ASPI and/or Mr. Eduardo Hochschild Beeck, carried out by themselves, or commissioned third parties (specialized companies, audit firms, banks, investment banks, or others) to perform valuation reports and/or the execution of a due diligence or similar regarding CEMPACASMAYO or that has involved CEMPACASMAYO; in which case you must:

3.1. Indicate the name of the entity that requested the valuation, due diligence, or similar.

3.2. Indicate the name of the entity that prepared the respective valuation report and/or carried out the due diligence or similar, specifying the date of preparation of said report and/or the period in which said due diligence or similar was carried out.

3.3. Present a full copy of the valuation report, in accordance with the provisions of Articles 3 and 4, and Annex 1, numeral 24, of the material events regulations, if applicable.

To our knowledge, in the last three (3) years, neither the Company nor Inversiones ASPI nor Mr. Eduardo Hochschild Beeck have carried out or commissioned due diligence processes or valuation reports from third parties regarding the Company, except for what is indicated in the following paragraph and the due diligence for the Transaction to which we refer in item 4 below.

In March 2026, the firm PricewaterhouseCoopers Sociedad Civil de Responsabilidad Limitada (PwC) issued a valuation of Inversiones Aspi S.A. commissioned by Farragut Holdings Inc. for the purpose of determining the income tax to be paid by Farragut Holdings Inc. derived from the sale of its shares issued in said company under the SPA. It should be noted that, for the purposes of said valuation, the Company limited itself to providing the necessary information for PwC to carry out the valuation commissioned by Farragut Holdings Inc.

Given the confidential and private nature of the valuation carried out by PwC, a copy of the valuation report will be sent to the General Superintendence of Conduct Supervision on this same date in a confidential manner.

Taking into account the material event of April 06, 2026, cited in item (vi) of this official letter, through which your represented company disclosed that in the Board of Directors meeting of CEMPACASMAYO on September 09, 2025, the company’s participation in the audit process (due diligence) and in the agreements that the controlling shareholder maintains with Holcim and any third party for the potential transfer of its shares had been approved; your represented company must:

4.1. Indicate the name of the entity or entities in charge of (or that have participated in) the due diligence process or similar and/or valuation within CEMPACASMAYO or that has involved CEMPACASMAYO.

4.2. Specify whether the results of said processes materialized in a valuation report (or in a different document), in which case, you must present a full copy thereof, in accordance with the provisions of Articles 3 and 4, and Annex 1, numeral 24, of the Material Events Regulations.

4.3. Indicate the date on which CEMPACASMAYO became aware of the report indicated in the previous numeral, if applicable.

As is customary in this type of operation, the due diligence process for the Transaction was carried out by the buyer Holcim Ltd. and its advisors In this regard, Holcim Ltd. has informed us that the due diligence process was led by Holcim and had the assistance of (i) The law firm Estudio Muñiz, Olaya, Meléndez, Castro, Ono & Herrera and the law firm Freshfields US LLP for legal matters and (ii) The firm Deloitte & Touche S.R.L. for tax/financial matters. Likewise, Holcim Ltd. has informed us that, as a result of the aforementioned due diligence, no valuation reports were issued, but only due diligence summaries

Calle La Colonia N° 150,

Urb. El Vivero - Santiago de Surco

Telf: 317-6000

Indicate if, to date, CEMPACASMAYO has become aware of the existence of any valuation report other than that indicated in the previous item related to the Transaction. In the affirmative case, you must indicate the name of the entity that requested it, the entity that carried it out, and the date of its preparation; being required to present a full copy thereof, within the framework of the provisions of Articles 3 and 4, and Annex 1, numeral 24, of the Material Events Regulations.

We are not aware of any valuation report other than the one indicated in our response to question 3 of the Official Letter. Likewise, Holcim Ltd. has informed us that only the valuation commissioned by Farragut Holdings Inc. mentioned in item 3 above was carried out.

Considering that the Transaction closed on March 30, 2026, the following is required:

6.1. Report what the total price and per-share price paid in the acquisition of 50.01% of the common shares representative of the capital stock of CEMPACASMAYO was, reflecting the entirety of the economic consideration directly and indirectly paid by Holcim.

6.2. Indicate what factors were taken into account for the determination of the price, such as: asset valuation, synergies, adjustments, retentions, contingent payments, benefits, or transfers of value associated with the acquisition of control of CEMPACASMAYO, among others.

Below, we address your queries based on the information provided by Holcim Ltd:

No price per share of Pacasmayo has been expressly agreed upon. Holcim Ltd. paid a total price equivalent to S/ 1,640,327,224.69 for 99.992136% of Inversiones Aspi S.A., which represents 264,602,461 shares representative of its capital stock. This would imply an approximate price per share of Inversiones Aspi S.A. paid equivalent to S/ 6.199239439553.

The factors taken into account for the determination of the price paid by Holcim for the acquisition of the 50.01% indirect stake in the common shares representative of the Company’s capital stock were the following:

Macroeconomic dynamics: The Peruvian macroeconomic environment and regional forecasts for the cement segment and the infrastructure segment.

Due Diligence: A standard due diligence process in financial, legal, and tax matters, including the evaluation of Pacasmayo’s audited financial statements.

Synergies: Expectations of operational efficiencies and application of Holcim’s technical know-how (know-how).

Adjustments: Standard M&A adjustments corresponding to net debt at the closing of the operation.

Disclose that, as a consequence of the acquisition of the shares of Inversiones ASPI by Holcim, the obligation has been generated on the part of said acquirer to formulate a subsequent OPA on the common shares representative of the capital stock of CEMPACASMAYO, specifying the percentage of significant participation acquired indirectly in CEMPACASMAYO.

Through a material event dated May 14, 2026, the Company complied with this requirement.

Disclose that the acquirer Holcim has requested the SMV to initiate the selection process for the valuation entity that will determine the minimum price of the common shares of CEMPACASMAYO to be taken into account for the formulation of the subsequent OPA.

Through a material event dated May 14, 2026, the Company complied with this requirement.

It should be noted that the responses indicated in this communication are based on the information provided by Holcim Ltd., according to the attached communication.

With nothing further to add, we remain yours truly.
