| Attention: | Gabriela Dañino – Legal Director |
| Reference: | Request for an extension of the deadline to commence the Tender Offer for Cementos Pacasmayo S.A.A., submitted by letter dated July
31, 2026 |
Dear Sirs:
Holcim Ltd. (“Holcim”),
duly represented by Messrs. (i) Norberto German Ledea, holder of Foreigner Identification Card No. 008820356; and (ii) Juan Carlos Vélez
Gadea, holder of National Identity Document No. 41163455, pursuant to the powers of attorney registered under Entry A00001 of Electronic
Record No. 16135683 of the Registry of Legal Entities of the Lima Registry Office, with address for these purposes at Av. Las Begonias
475, Sixth Floor, district of San Isidro, province and department of Lima, hereby informs you of the following:
In connection with the Public Tender
Offer for the shares representing the share capital of Cementos Pacasmayo S.A.A. (“CPAC”), on July 31, 2026, we submitted
a communication to the Superintendence of the Securities Market (“SMV”) clarifying certain matters related to the following
exemptions previously requested from the SMV, as reported to CPAC on June 17, 2026:
| (i) | To carry out the Tender Offer for the shares representing CPAC’s share capital through Inversiones
ASPI S.A. (“ASPI”), a subsidiary directly controlled by Holcim with a 99.99% ownership interest and CPAC’s majority
shareholder. The Tender Offer would be launched for up to 100% of the remaining shares representing CPAC’s share capital that are
not owned by ASPI; and |
| (ii) | For purposes of the Tender Offer, to submit: (i) Holcim’s audited annual consolidated financial
statements for fiscal year 2025; and (ii) Holcim’s unaudited interim consolidated financial statements as of June 2026 and, if applicable,
Holcim’s unaudited interim separate financial statements as of June 2026. |
Additionally, considering that, as of
the date hereof, the valuation entity responsible for determining the minimum price of the Tender Offer has not yet been appointed, we
have requested that the Board of Directors of the SMV exceptionally grant us an extension of the deadline to commence the Tender Offer
for a period of up to sixty (60) business days from the appointment of the valuation entity responsible for carrying out the Tender Offer
for the shares representing CPAC’s share capital, or five (5) business days after the issuance of the valuation entity’s report,
whichever occurs first.

Sincerely,
