Report on review of interim condensed consolidated unaudited financial statements

To the Board of Directors and Shareholders of Cementos Pacasmayo S.A.A.

Introduction

We have reviewed the accompanying interim condensed consolidated unaudited statement of financial position of Cementos Pacasmayo S.A.A. (a Peruvian company) and its Subsidiaries (together the “Group”) as of September 30, 2023, and the related interim condensed consolidated unaudited statements of profit or loss, other comprehensive income, changes in equity and cash flows for the three and nine-month periods then ended, and explanatory notes. Management is responsible for the preparation and presentation of these interim condensed consolidated unaudited financial statements in accordance with IAS 34 Interim Financial Reporting (IAS 34). Our responsibility is to express a conclusion on these interim condensed consolidated unaudited financial statements based on our review.

Scope of review

We conducted our review in accordance with International Auditing Standard on Review Engagements (ISRE) 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review of interim financial information consists of making inquiries, primarily of the persons responsible for financial and accounting matters and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the accompanying interim condensed consolidated unaudited financial statements are not prepared, in all material respects, in accordance with IAS 34.

The interim condensed consolidated unaudited financial statements of the Company and its subsidiaries (hereinafter the “Group”) as of September 30, 2023 and for the nine-month period then ended, were approved for issuance by the Company’s Management on October 25, 2023. The consolidated audited financial statements as of December 31, 2022 have been approved by the General Meeting of Shareholders, on March 24, 2023.

The interim condensed consolidated unaudited financial statements of the Group have been prepared in accordance with IAS 34 Interim Financial Reporting as issued by the International Accounting Standards Board (IASB) and have been prepared on a historical cost basis, except for financial instruments designated at fair value through other comprehensive income (OCI) and derivatives financial instruments that have been measured at fair value.

The Group has prepared the financial statements on the basis that it will continue to operate as a going concern.

Notes to interim condensed consolidated unaudited financial statements (continued)

New standards, interpretations and amendments

The accounting policies adopted in the preparation of the interim condensed consolidated unaudited financial statements are consistent with the policies considered in the preparation of the consolidated financial statements of the Group at December 31, 2022, except for the adoption of new standards effective as of 1 January 2022. The standards and interpretations relevant to the Group, that are effective since January 1, 2023 are disclosed below.

Definition of Accounting Estimates - Amendments to IAS 8

The amendments to IAS 8 clarify the distinction between changes in accounting estimates, and changes in accounting policies and the correction of errors. They also clarify how entities use measurement techniques and inputs to develop accounting estimates.

The amendments had no impact on the Group’s interim condensed consolidated unaudited financial statements.

Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2

The amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements provide guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures.

The amendments had no impact on the Group’s interim condensed consolidated unaudited financial statements but are expected to affect the accounting policy disclosures in the Group’s annual consolidated financial statements.

Deferred Tax related to Assets and Liabilities arising from a Single Transaction – Amendments to IAS 12

The amendments to IAS 12 Income Tax narrow the scope of the initial recognition exception, so that it no longer applies to transactions that give rise to equal taxable and deductible temporary differences such as leases and decommissioning liabilities. The amendments had no impact on the Group’s interim condensed consolidated financial statements.

The interim condensed consolidated unaudited financial statements comprise the financial statements of the Company and its subsidiaries as of September 30, 2023 and 2022, and for the three and nine-month period ended September 30, 2023 and 2022 (unaudited).

This is an opposite position to what is established by the Constitutional Court in the STC Exp. N° 1043-2013-PA/TC that declares founded the writ of protection presented by the Company and its right to calculate the Mining Royalty exclusively based on the value of the mining component, without considering in any way the value of the final products derived from industrial and manufacturing processes.

Derivatives assets of hedging –

Foreign currency risk –

As of December 31, 2022, the Group maintains cross currency swap contracts for a nominal amount of US$132,000,000, with maturity in February 2023 and a rate of 2.97%. Of this total, US$131,612,000 have been designated as hedging instruments for Senior notes that are denominated in U.S. dollars, with the intention of reducing the foreign exchange risk.

The cash flow hedge of the expected future payments was assessed to be highly effective and in the interim condensed consolidated unaudited statement of other comprehensive income is included an unrealized gain of S/2,154,000 and S/1,647,000 for the nine-month period ended September 30, 2023 and September 30, 2022, respectively.

As of September 30, 2023 the Group settled the Cross currency swap contracts on their maturity date in relation with the payment of international bonds in dollars mentioned in note 9(a).

Derivative assets from trading -

As of September 30, 2022, cross currency swaps that do not have an underlying relationship amounts to US$388,000, have been designated as trading. The effect on profit or loss from its measurement at fair value was a loss of S/2,000 for the nine-month period ended September 30,2022.

Notes to interim condensed consolidated unaudited financial statements (continued)

In February 2023, cross currency swaps from trading have been settled and obtained a gain of S/19,000 which was recognized in the interim condensed consolidated unaudited statement of profit or loss for the nine-month period ended September 30, 2023 presented in “Net profit (loss) for valuation of trading derivative financial instruments” caption.

Set out below is a comparison of the carrying amounts and fair values of financial instruments of the Group, as well as the fair value accounting hierarchy:

All financial instruments for which fair value is recognized or disclosed are categorized within the fair value hierarchy, based on the lowest level input that is significant to the fair value measurement as a whole, as follows:

Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

Level 2 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

Notes to interim condensed consolidated unaudited financial statements (continued)

For assets and liabilities that are recognized at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy. As of September 30, 2023 and December 31, 2022, there were no transfers between the fair value hierarchies.

Management assessed that cash and cash equivalents, trade and other receivables and other current liabilities approximate their carrying amounts largely due to the short-term maturities of these instruments.

The following methods and assumptions were used to estimate the fair values:

A credit valuation adjustment (CVA) is applied to the “Over-The-Counter” derivative exposures to take into account the counterparty’s risk of default when measuring the fair value of the derivative. CVA is the mark-to market cost of protection required to hedge credit risk from counterparties in this type of derivatives portfolio. CVA is calculated by multiplying the probability of default (PD), the loss given default (LGD) and the expected exposure (EE) at the time of default.

A debit valuation adjustment (DVA) is applied to incorporate the Group’s own credit risk in the fair value of derivatives (that is the risk that the Group might default on its contractual obligations), using the same methodology as for CVA.

Operating lease commitments – Group as lessor

As of September 30, 2022, the Group, as lessor, has a land lease with Compañía Minera Ares S.A.C., a related party of Inversiones ASPI S.A. This lease is annually renewable, and provided a rent for the nine-month period ended September 30, 2023 and 2022 for S/860,000 and S/878,000, respectively.

Notes to interim condensed consolidated unaudited financial statements (continued)

Consortium contract –

On December 19, 2022, Distribuidora Norte Pacasmayo S.R.L., subsidiary of the Group, has subscribed a collaboration contract with a third party, with the purpose to participate together in the project “Mejoramiento del Sistema de Pistas y Cerco Perimétrico del Aeropuerto de Piura”. The mentioned contract is valid for a maximum of 2 years and 11 months.

On this matter, the Company has communicated to the tax authority the subscription of the collaboration contract which will take independent accounting and Distribuidora Norte Pacasmayo S.R.L. will be the contracting party that will act as operator of the contract.

Capital commitments

As of September 30, 2023, the Group had no significant capital commitments.

Environmental matters

The Group exploration and exploitation activities are subject to environmental protection standards. Such standards are the same as those disclosed on the consolidated financial statement as of December 31, 2022.

Tax situation

The Company is subject to Peruvian tax law. As of September 30, 2023 and 2022, the income tax rate is 29.5 percent of the taxable profit after deducting employee participation, which is calculated at a rate of 8 to 10 percent of the taxable income.

For purposes of determining income tax, transfer pricing transactions with related companies and companies resident in territories with low or no taxation, must be supported with documentation and information on the valuation methods used and the criteria considered for determination. Based on the analysis of operations of the Group, Management and its legal advisors believe that as a result of the application of these standards will not result in significant contingencies for the Group as of September 30, 2023 and December 31, 2022.

During the four years following the year tax returns are filed, the tax authority has the power to review and, as applicable, correct the income tax computed by each individual company.

The income tax and value-added tax returns for the following years are open for review by the tax authority

Due to possible interpretations that the tax authorities may give to legislation in effect, it is not possible to determine whether any of the tax audits that may be performed will result in increased liabilities for the Group. For that reason, tax or surcharge that could arise from future tax audits would be applied to the income during the period in which it is determined. However, in management’s opinion, any possible additional payment of taxes would not have a material effect on the interim condensed consolidated financial statements as of September 30, 2023 and the consolidated financial statements as of December 31, 2022.

Legal claim contingency

As of September 30, 2023, the Group has received claims from third parties in relation with its operations which in aggregate represent S/929,000 that corresponded to labor claims from former employees.

Management expects that these claims will be resolved within the next five years based on prior experience; however, the Group cannot assure that these claims will be resolved within this period because the authorities do not have a maximum term to resolve cases.

The Group has been advised by its legal counsel that it is only possible, but not probable, that these actions will succeed. Accordingly, no provision for any liability has been made in these interim condensed consolidated unaudited financial statements.

Mining royalty

The Group signed agreements with third parties and with Peruvian Government related to the use of concessions for extraction activities on process of cement production. The information of the payment of royalties are reveled on the consolidated audited financial statements of the Group as of December 31, 2022.

Notes to interim condensed consolidated unaudited financial statements (continued)

For management purposes, the Group is organized into business units based on their products and activities, and have three reportable segments as follows:

No operating segments have been aggregated to form the above reportable operating segments.

Management monitors the profit before income tax of each business units separately for the purpose of making decisions about resource allocation and performance assessment.

Transfer prices between operating segments are on an arm’s length basis in a similar manner to transactions with third parties.
