RATIO ANALYSIS OF THE CONSOLIDATED FINANCIAL STATEMENTS

1. ANALYSIS OF FINANCIAL POSITION

Statement of financial position

The principal components of assets and liabilities at the end of each period are as follows:

	03-31-2024		12-31-2023		Variation
Assets	ThU.S.$		ThU.S.$		ThU.S.$
Current assets		4,098,886		4,175,578		(76,692	)
Non-current assets		13,726,800		13,734,786		(7,986	)
Total assets		17,825,686		17,910,364		-0.47	%

	03-31-2024		12-31-2023		Variation
Liabilities	ThU.S.$		ThU.S.$		ThU.S.$
Current liabilities		2,103,730		2,071,742		31,988
Non-current liabilities		7,676,668		7,829,593		(152,925	)
Non–controlling interests		6,845		6,583		262
Equity attributable to parent company		8,038,443		8,002,446		35,997
Total net equity and liabilities		17,825,686		17,910,364		-0.47	%

As of March 31, 2024, total assets decreased MU.S.$ 85 compared to December 31, 2023, equivalent to a 0.47% variation. This variation was driven mainly by a decrease in trade and other current receivables, current tax assets and other non-current financial assets which were offset by a lower balance of deferred tax assets and cash and cash equivalents.

In turn, total liabilities decreased by MU.S.$ 121 principally driven by decreases in financial liabilities and trade payables, which were offset by higher balances of non-financial liabilities by provision of minimum dividend recorded in the period 2023.

The main financial and operational indicators related to the statement of financial position as of the dates and for the periods indicated below are as follows:

Liquidity ratios	03-31-2024		12-31-2023
Current liquidity (current assets / current liabilities)		1.95		2.02
Acid ratio ((current assets-inventories, biological assets) / current liabilities)		1.11		1.16

Debt indicators	03-31-2024		12-31-2023
Debt to equity ratio (total liabilities / equity)		1.22		1.24
Short-term debt to total debt (current liabilities / total liabilities)		0.22		0.21
Long-term debt to total debt (non-current liabilities / total liabilities)		0.78		0.79

		03-31-2024				03-31-2023
Financial expenses coverage ratio (earnings before taxes + interest expense / interest expense)			1.85				(0.40	)

Activity ratio	03-31-2024		12-31-2023
Inventory turnover-time (cost of sales / inventories + current biological assets)		2.59		2.66
Inventory turnover-time (excluding biological assets) (Cost of sales /inventory)		3.30		3.31
Inventory permanence-days ((inventories + biological assets) /cost of sales)		138.95		135.50
Inventory permanence-days (excluding biological assets) (inventory / cost of sales)		109.17		108.89

As of March 31, 2024, the short-term debt to total debt ratio represented 22% of total liabilities (21% as of December 31, 2023).

Our financial expenses coverage ratio increased from (0.40) to 1.85, mainly due to the profits before taxes generated for the three-months period ended March 31, 2024, compared to the losses before taxes generated in the same period of 2023.

b) Statement of profit or loss

Profit before income tax

We recorded a profit before income tax of approximately MU.S.$ 86 compared to a loss of approximately MU.S.$ 112 in the same period of 2023. The variation of MU.S.$ 198 is explained by the factors described in the following table:

2. MAIN SOURCES OF FINANCING

Arauco’s financing needs are mainly covered through the capital markets, with bond issuances and credits obtained from banks and financial institutions serving as the main sources of financing.

For short-term borrowing, Arauco follows a liquidity policy which indicates the amounts and institutions from which it can borrow according to several conditions defined in the policy.

In the case of long-term debt, corporate bond issuances in the local market and also in the international markets are used as sources of new resources.

Another source of long-term financing corresponds to borrowings from banks and financial institutions around the world.

3. MARKET SITUATION

Turnover for the first quarter of 2024 increased by 42% compared to the same period of 2023. There was an increase in sales volume offset by a decrease in price. In terms of grades, all prices were lower, except for unbleached pulp.

During the first quarter of 2024, the pulp market was quite active in Europe in demand. In the other markets, pulp remained relatively stable in demand. Total global short fiber inventories started the quarter at low level and increased slightly as the months progressed, unlike long fiber inventories, which remained stable.

In China, the quarter began with a somewhat weak pulp market. However, after the Chinese New Year, the market started to reactivate, with an increase in operating rates of paper and packaging mills. Prices of the various types of paper have remained relatively stable, mainly due to surplus capacity in some end-product industries. Pulp inventories at the main ports increased after the New Year; although they subsequently consistently decreased through the end of the quarter. As regards to prices, the average price of long-fiber pulp decreased, while the price of short-fiber pulp remained unchanged.

In Europe, pulp demand remained favorable for several reasons. First, a decrease in paper from Asia due to logistical problems in the Suez Canal. Additionally, the operating rates of the paper mills have increased due to the shutdown of several paper mills and the increase in demand for these products. The tissue industry also displayed a positive demand. As to pulp supply, there has been a decrease in the supply of long fiber, mainly due to the strike of transporters in Finland and operational problems in another long fiber plant. This has resulted in a higher demand for short fiber as paper manufacturers are trying to substitute the greatest amount of long fiber for short fiber. Short fiber prices increased 23% during the quarter.

The textile pulp market improved throughout the first quarter, with average prices increasing during the first few months. This was caused mainly by improved customer demand, due to an increase in the operating rates of textile pulp mills and slight price increases of end products. Additionally, end product inventories were below the average level.

Production during the first quarter of 2024 was 52% higher than production in the same period of 2023. This increase occurred due to (i) the commissioning of Arauco's Line 3, which began operating in January 2023, (ii) the unscheduled shutdown of the Constitución mill, (iii) the unscheduled shutdown of the Argentina mill, (iv) and the stoppage of the Nueva Aldea mill for a few days as a result of the fires.

Wood Products Business

Sawn timber

For sawn timber, we observed higher sales during the first quarter of 2024, when compared to the same period of 2023. In general, markets continue to show the effects of low economic activity. Nonetheless, given the lower supply, we experienced a slight improvement in prices. China continues to be affected by a sluggish local economy and lower construction demand. However, in multiple markets, inventories have started to normalize. For the upcoming months, we believe that we will continue to see tight demand, but also supply issues, which could continue to have a positive impact on prices.

In Remanufacturing in the U.S., a slight improvement in demand continued during this first quarter of 2024, which has not resulted in an improvement in prices, which remained lower than in the same period of 2023. Interest rates remain high in the U.S., and therefore, construction is affected and a highly competitive pressure is still in place. In addition, local supply and from Asia and Latin America increased during this first quarter of 2024. For the next quarter, business is expected to improve due to seasonality.

Plywood

During the first quarter of 2024, sales showed an improvement when compared to the same quarter of 2023. Generally speaking, demand continues to be affected by inflation and high interest rates, thus impacting the construction and renovations sector. Nevertheless, supply from competitors in Chile, Brazil, Finland, and New Zealand has decreased, causing an increase of prices in some markets. In addition, inventories normalized during 2024, reaching healthier levels. In the case of North America, demand and prices remain stable and are expected to improve. Going forward, the second quarter of 2024 is expected to show a minor improvement.

Panels (MDF, PB, Melamine)

In this first quarter of 2024, volumes and prices continued to be affected by enhanced supply in Latin America, especially in MDF. This is in addition to the negative moment of demand (construction), which is affected by inflation, low economic growth, and high rates. For the second quarter of 2024, the region is expected to continue facing this oversupply.

4. ANALYSIS OF CASH FLOW

The main components of cash flow in each period are as follows:

	03-31-2024 ThU.S.$			12-31-2023 ThU.S.$
Positive (negative) Cash flow
Net cash flows from (used in) operating activities		492,399			103,750

Cash flows from (used in) financing activities:		(65,093	)		437,767
Obtaining and paying borrowings and bonds		519			-
Payments of lease liabilities		(48,683	)		451,424
Dividends paid		(16,410	)		(13,184	)
Others		-			(473	)

Cash flows from (used in) investment activities:		(379,024	)		(330,774	)
Purchase and sale of property, plant and equipment		(198,197	)		(222,862	)
Purchase and sale of biological assets		(116,572	)		(106,685	)
Purchase and sale of intangible assets		(1,167	)		(1,371	)
Additions (disposals), investments in subsidiaries, joint ventures and associates		(75,870	)		-
Others		12,782			1,444
Positive (negative) net cash flow		48,801			210,743

Our cash flow from operating activities increased to MU.S.$ 492 for the current period (compared to the positive balance of MU.S.$ 104 for the same period in 2023), resulting mainly from lower payments to suppliers in the current period.

The cash flow from financing activities showed a negative balance of MU.S.$ 65 for the current period (compared to the positive balance of MU.S.$ 438 for the same period in 2023). This was mainly due to an increase in payments of liabilities for borrowings and bonds.

Regarding the cash flow from investment activities, the balance decreased to MU.S.$ 379 (compared to a negative balance of MU.S.$ 331 for the same period of 2023), mainly due to a increase in payments for purchases of companies in Uruguay (50%), which was partially offset by an increase in sales of property, plant and equipment.

5. MARKET RISK ANALYSIS

In respect of the economic risks resulting from interest rate variations, the Company maintained, as of March 31, 2024, a ratio of fixed rate debt to total consolidated debt of approximately 86,7%, which we believe is consistent with industry standards.

Regarding variations in prices of pulp and forestry products, the Company does not participate in futures trading, which allows it to maintain one of the lowest cost structures in the industry and have these risks bounded.

The Company and most of its subsidiaries maintain their accounting records and prepare their financial statements in U.S. dollars. Most of their revenues (and accordingly accounts receivable) are denominated in U.S. dollars, and most financial liabilities are either denominated in U.S. dollars or are covered by exchange rate swaps. As a result, exposure to exchange rate fluctuations has decreased significantly.

The consolidated financial statements as of March 31, 2024 include a detailed analysis of the risks associated with the business of Arauco (see Note 23).

Additionally, the Company is registered as a non-accelerated filer in the Securities and Exchange Commission (SEC) of the United States of America.

The Company’s head office address is El Golf Avenue 150, 14^thfloor, Las Condes, Santiago, Chile.

Arauco is principally engaged in the production and sale of products related to the forestry and timber industries. Its main operations are focused on business areas of pulp and wood products.

Functional and Presentation Currency

Arauco and most of its subsidiaries determined the United States (“U.S.”) dollar as its functional currency since the majority of its revenues from sales of its products are derived from exports denominated in U.S. dollars, while their costs of sales are to a large extent related or indexed to the U.S. dollar.

For the pulp reportable segment, most of the sales are exports denominated in U.S. dollars and costs are mainly related to plantation costs which are settled in U.S. dollars.

For the wood reportable segment, although total sales include a mix of domestic and exports sales, prices of the products are established in U.S. dollars, which is also the case for the cost structure of the related raw materials.

In relation to the cost of sales, although labor and services costs are generally billed and paid in local currency, these costs are not as significant as the costs of raw materials, which are driven mainly by global markets and therefore, influenced mostly by the U.S. dollar.

The currency used to finance operations is mainly the U.S. dollar.

The presentation currency of the consolidated financial statements is the U.S. dollar. Figures on these consolidated financial statements are presented in thousands of rounded U.S. dollar (ThU.S.$).

Summary of significant accounting policies

Basis for preparation of the consolidated financial statements

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB) and they represent the explicit and unreserved adoption of IFRS.

These consolidated financial statements have been prepared on a historical cost basis, except for biological assets and certain derivative financial instruments which are measured at revalued amounts or fair value at the end of each period as explained in the following significant accounting policies.

Critical accounting estimates and judgments

The preparation of these consolidated financial statements, in accordance with IFRS, requires management to make estimates and assumptions that affect the carrying amounts reported. These estimates are based on historical experience and various other assumptions that are considered to be reasonable. Actual results may differ from these estimates. Management believes that the accounting policies below are the critical judgments that have the most significant effect on the amounts recognized in the consolidated financial statements.

- Biological assets

The recovery of forest plantations is based on discounted cash flow models which means that the fair value of biological assets is calculated using cash flows from continuing operations on a discounted basis, based on our sustainable forest management plans and the estimated growth of forests.

The measurement of the fair value of the biological assets is determined using a discounted cash flow model. Our cash flow projections include significant judgments and assumptions relating to discount rates, estimated growth of the forests and sales margins. This valuation is performed on the basis of each identifiable farm block and for each type of tree. The main considerations used to calculate the valuation of forest plantations and a sensitivity analysis are presented in Note 20.

- Litigation and contingencies

Arauco and its subsidiaries are subject to certain litigation proceedings. Future impact on Arauco’s financial condition derived from such litigations is estimated by management, in collaboration with its legal advisors. Arauco applies judgment when interpreting the reports of its legal advisors who provide updated estimates of the legal contingencies at each reporting period and/or at each time a modification is determined to be necessary. For a description of current litigations see Note 18.

Consolidation

The consolidated financial statements include all entities over which Arauco has the power to direct the relevant financial and operating activities. Subsidiaries are consolidated from the date on which control is obtained and up to the date that control ceases.

Specifically, a company controls an investee or subsidiary if, and only if, they have all of the following:

(a) power over the investee, i.e. the investor has existing rights which give it the ability to direct the relevant activities (the activities that significantly affect the investee's returns);

(b) exposure or rights to variable returns from involvement with the investee; and

When Arauco holds less than the majority of the voting rights in a company in which it participates, it nonetheless has the power over said company - when these voting rights are enough - to grant it in practice the ability to unilaterally direct said company's relevant activities. Arauco takes into account all facts and circumstances in order to assess if the voting rights in a company in which it participates are enough for granting it the power, including:

a) the size of the investor’s holding of voting rights relative to the size and dispersion of holdings of the other vote holders;

b) potential voting rights held by the investor, other vote holders or other parties;

c) rights arising from other contractual arrangements; and

d) any additional facts and circumstances that indicate the investor has, or does not have, the current ability to direct the relevant activities at the time that decisions need to be made, including voting patterns at previous shareholders’ meetings.

The Company will reevaluate whether or not it holds control of a company in which participates if the facts and circumstances indicate that changes have occurred in one or more of the three elements of control mentioned above.

Consolidation of an investee shall begin from the date the investor obtains control of the investee and cease when the investor loses control of the investee. An entity includes the income and expenses of an acquired or sold subsidiary in the consolidated financial statements from the date it gains control until the date when the entity ceases to control the subsidiary.

The profit or loss of each component of other comprehensive income is attributed to owners of the parent company and the non-controlling interest, as appropriate. Total comprehensive income is attributed to the owners of the parent company and non-controlling interests even if the results of the non-controlling interest have a deficit balance.

If a subsidiary uses accounting policies other than those adopted in the consolidated financial statements for transactions and other events in similar circumstances, appropriate adjustments are made to the consolidated financial statements of subsidiaries in order to ensure compliance with Arauco's accounting policies.

Amounts in thousands of U.S. dollars, except as indicated

All intercompany transactions and unrealized gains and losses from subsidiaries have been fully eliminated from these consolidated financial statements and non-controlling interest is presented in the consolidated statement of financial position within equity.

The consolidated financial statements at the end of this period include the assets, liabilities, income and expenses of the subsidiaries shown in Note 13.

Certain consolidated subsidiaries have Brazilian real, Mexican pesos, Canadian dollars, Chilean pesos and Argentine pesos as their functional currencies. For consolidation purposes, the financial statements of those subsidiaries have been prepared in accordance with IFRS and translated as indicated in Note 1 (e) (ii).

The subsidiaries non-controlling interests in profits or losses and in the equity are presented separately in the consolidated statement of comprehensive income, in the consolidated statement of changes in equity and in the consolidated statement of financial position respectively.

Segments

Arauco has defined its reportable segments according to its business areas, based on the products and services sold to its customers. This definition is consistent with the management, resource allocation and performance assessment made by key personnel responsible for making relevant decisions related to the Company’s operation. The personnel responsible for making such decisions are the Executive Vice-president and the Chief Executive Officer who are the highest authorities for making decisions and are supported by the Vice-presidents of each segment.

Based on the aforementioned process, the Company has established reportable segments according to the following business units:

Pulp

Wood products

Refer to Note 24 for detailed financial information by reportable segment.

Functional currency

(i)

Functional currency

All items in the financial statements of Arauco and each of its subsidiaries, associates and jointly controlled entities are measured using the currency of the primary economic environment in which each entity operates (the functional currency). The consolidated financial statements are presented in U.S. dollars, which is Arauco’s functional and presentation currency.

(ii)

Translation to the presentation currency of Arauco

For the purposes of presenting consolidated financial statements, assets and liabilities of Arauco’s operations in a functional currency different from Arauco’s are translated into U.S. dollars using exchange rates prevailing at the end of each reporting period. Income and expense items are translated at the average exchange rates for the period, unless exchange rates fluctuate significantly during that period, in which case the exchange rates at the dates of the transactions are used. Exchange rate differences are recognized in other comprehensive income and accumulated in “Other reserves” within equity.

(iii)

Foreign currency transactions

Transactions in currencies other than the functional currency are recognized at the exchange rates prevailing at the dates of the transactions. Profit or loss on transactions in currencies other than the functional currency resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies, are recognized in the consolidated statements of profit or loss, except those which are recorded in other comprehensive income and accumulated in equity such as cash flows hedging derivatives.

Cash and cash equivalents

Cash and cash equivalents include cash-on-hand, deposits held on demand at financial entities and other short-term highly liquid investments with an original maturity of three months or less and which are subject to an insignificant risk of changes in value.

Financial instruments

Financial assets

Initial classification

Arauco classifies its financial assets into the following categories: fair value through profit or loss and amortized cost.

Arauco does not have financial assets at fair value through other comprehensive income.

The classification is based on the business model used to manage the assets and the characteristics of their contractual cash flows.

Management determines the classification of its financial assets at the time of their initial recognition.

(a) Financial assets at fair value through profit or loss: these instruments are initially measured at fair value. Net income and losses, including any income from interest or dividends, are registered in the profit or loss of the period. Financial assets are classified in the category of financial assets at fair value through profit or loss when they are maintained for negotiation or designated in their initial registration as assets at fair value through profit or loss. A financial asset can be classified in this category if it is acquired mainly for the purposes of being sold in the short-term. Gain or losses of assets held for negotiations are registered in the consolidated statements of profit or loss, and the related interest is registered independently as financial income. Derivatives are classified as acquired for negotiation also unless they are designated as hedging instruments.

(b) Assets measured at amortized cost: they are initially registered at the fair value of the transaction, adding or subtracting the transaction costs that are directly attributable to the issuance of the financial asset or financial liability. The financial asset is maintained within a business model, the objective of which is to maintain financial assets to obtain contractual cash flows and the contractual conditions of the asset give rise, on specified dates, to cash flows that are solely payments of principal and interest (“SPPI”) over the amount of the outstanding principal.

Subsequent measurement

Financial instruments are subsequently measured at fair value through profit or loss or amortized cost.

The classification is based on two criteria: i) the Company’s business model for the management of financial instruments, and ii) whether the contractual cash flows related to the financial instruments represent “Solely Payments of Principal and Interest”.

a) Financial assets at fair value through profit or loss: these instruments are subsequently measured at fair value. Net earnings and losses, including income from interest and dividends, are registered as profits or losses for the period. These instruments are held for negotiation, and they are mainly acquired to be sold in the short-term. Derivatives are also classified as held for negotiation, unless they are registered as hedging instruments. Financial instruments of this type are classified as other current and non-current financial assets. They are subsequently valuated by determining their fair value, registering changes in value in the consolidated statements of profit or loss, in the items of financial income or financial costs.

b) Financial assets measured at amortized cost: These instruments are subsequently measured at amortized cost minus accumulated amortizations, using the effective interest method and adjusted by loss allowance and volume discounts, in the case of financial assets. Financial income and expenses, foreign exchange income and losses, and impairment are registered in results. Any earnings or losses due to initial or subsequent reductions of the value of the asset are registered in the statement of profit or loss of the period. Borrowings and receivables are non-derivative financial instruments with fixed or determinable payments not traded in any active market. They are registered at amortized cost, registering accrued conditions directly in profit or loss.

Arauco measures accumulated losses in a quantity equivalent to expected credit losses during the lifelong commitment. Expected credit losses are based on contractual cash flow differences based on the allowance of each contract and the cash flows that Arauco expects. The difference is then discounted based on an approximation of the asset’s original effective interest rate. The asset’s carrying value is reduced as the allowance is used, and the loss is recognized in sales expenses in the consolidated statements of profit or loss. When an account receivable cannot be collected, it is regularized against the allowance account for receivables. Subsequent recoveries of previously impaired amounts are recognized as a debit in distribution cost.

Derivative financial instruments are explained in Note 1 h).

Financial liabilities

Arauco classifies its financial liabilities as follows: fair value through profit or loss, derivatives designated as effective hedging instruments and amortized costs.

Management determines the classification of its financial liabilities upon initial recognition. Financial liabilities are derecognized when the obligation is cancelled, settled or expired. When an existing financial liability is replaced with another of the same provider under substantially different terms, or where the terms of an existing liability are substantially amended, such exchange or modification is treated as a write-off of the original liability, with a new liability being recognized, and the difference between the respective carrying amounts is recognized in the consolidated statement of profit or loss.

Financial liabilities are initially recognized at fair value, and in the case of borrowings, they include the costs directly attributable to the transaction. The subsequent measurement of the financial liabilities depends on their classification:

Financial liabilities at fair value through profit or loss

Financial liabilities are included in the category of financial liabilities at fair value through profit or loss when they are held for trading or originally designated at fair value through profit or loss. Income and losses from liabilities held for trading are recognized in profit or loss. This category includes non-designated derivatives for hedging accounting.

Financial liabilities at amortized cost

Other financial liabilities are subsequently valued at their amortized cost based on the effective interest rate method. The amortized cost is calculated taking into account any premium or acquisition discount and includes the costs of transactions that are an integral part of the effective interest rate. This category includes commercial accounts payable and other accounts payable, lease liabilities, as well as the borrowings included in other current and non-current financial liabilities.

h) Derivative financial instruments

(i) Derivative financial instruments - The Company enters into a variety of derivative financial instruments to manage its exposure to interest rate and foreign exchange rate risks, including foreign exchange forward contracts, interest rate swaps, currency swaps and zero cost collar contracts. The Company’s policy is to enter into derivatives contracts only for economic hedging purposes and there are no instruments with speculation objectives.

Derivatives are initially recognized at fair value at the date the derivative contracts are entered into and are subsequently re-measured at fair value at the end of each reporting period. The resulting gain or loss is recognized in profit or loss unless the derivative is designated as a hedging instrument and complies with hedge accounting requirements, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.

(ii) Embedded derivatives

The Company assesses the existence of embedded derivatives in financial instrument contracts. Derivatives embedded in non-derivative host contracts are treated as separate derivatives when they meet the definition of a derivative, their risks and characteristics are not closely related to those of the host contracts and the contracts are not measured at FVTPL as a whole. Arauco has determined that no embedded derivatives currently exist.

(iii) Hedge accounting

The Company designates certain hedging instruments as either fair value hedges or cash flow hedges.

At the inception of the hedge relationship, the entity documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, Arauco documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item attributable to the hedged risk.

-Fair value hedges

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognized in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

-Cash flow hedges

The effective portion of changes in the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in other comprehensive income and accumulated under the heading of cash flow hedging reserve. The gain or loss relating to the ineffective portion is recognized immediately in profit or loss, and is included in the Finance costs line item in the consolidated statement of profit or loss. Amounts previously recognized in other comprehensive income are reclassified to profit or loss in the periods when the hedged item affects profit or loss, in the same line as the recognized hedged item.

Hedge accounting is discontinued when the Group revokes the hedging relationship, when the hedging instrument expires or is sold, terminated, or exercised, or when it no longer qualifies for hedge accounting. Any gain or loss recognized in other comprehensive income and accumulated in equity at that time remains in equity and is recognized when the forecasted transaction is ultimately recognized in profit or loss. When a forecasted transaction is no longer expected to occur, the gain or loss accumulated in equity is recognized immediately in profit or loss.

i) Inventories

Inventories are measured at the lower of cost or net realizable value. Cost is determined using the weighted average cost method.

The cost of finished and in process products includes the cost of raw materials, direct labor, other direct costs and manufacturing overhead expenses.

Initial costs of harvested wood are determined at fair value less cost of sale at the point of harvest.

Biological assets are transferred to inventories when forests are harvested.

Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale.

When market conditions result in the production costs of a product exceeding its net realizable value, the inventories are written-down to their net realizable value. This write-down also includes obsolescence amounts resulting from slow moving inventories and technical obsolescence.

Spare parts that will be consumed in a period of less than twelve months are presented in inventories and recognized as an expense when they are consumed.

j) Non-current assets held for sale

Arauco classifies certain property, plant and equipment, intangible assets, investments in associates and disposal groups (groups of assets to be sold together with their directly associated liabilities) as non-current assets held for sale which as of the date of the consolidated statements of financial position are the subject of active sale efforts which are estimated to be highly probable.

These assets or disposal groups are measured at the lower of the carrying amount or the fair value less the costs to sell, and are no longer depreciated or amortized from the time they are classified as non-current assets held for sale.

k) Business combinations

Arauco applies the acquisition method to account for a business combination. This method requires the identification of the acquirer, determination of the acquisition date, recognition and measurement of the identifiable assets acquired, the liabilities assumed and any non-controlling interest in the acquiree; and recognition and measurement of goodwill or a gain from a bargain purchase. Identifiable assets acquired and liabilities assumed and any contingent liabilities in a business combination are initially measured at fair value at the acquisition date, except:

-deferred tax assets or liabilities, and assets or liabilities related to employee benefit arrangements are recognized and measured in accordance with IAS 12 Income taxes and IAS 19 respectively;

-liabilities or equity instruments related to share-based payment arrangements of the acquiree or share-based payment arrangements of the Group entered into to replace share-based payment arrangements of the acquiree are measured in accordance with IFRS 3 at the acquisition date; and

-assets (or disposal groups) that are classified as held for sale in accordance with IFRS 5 Non-current assets held for sale and discontinued operations are measured in accordance with such standard.

Acquisition-related costs are accounted for as expenses when they are incurred, except for costs to issue debt or equity securities which are recognized in accordance with IAS 32 and IFRS 9.

A parent will present non-controlling interests in the consolidated statement of financial position within equity, separately from the equity of the owners of the parent company.

Changes in the ownership interest of a parent in its subsidiary that do not result in a loss of control are treated as equity transactions. Any difference between the amount by which non-controlling interests are adjusted and the fair value of the consideration paid or received is recognized directly in equity and attributed to owners of the parent company. No adjustment is made to the carrying amount of goodwill, neither gains nor losses are recognized in the statement of profit or loss.

Non-controlling interests that are present ownership interests and entitle their holders to a proportionate share of the entity's net assets in the event of liquidation may initially be measured either at fair value or at the present ownership instruments' proportionate share of non-controlling interests, in the recognized amounts of the acquirer’s identifiable net assets. The choice is made on a transaction-by-transaction basis.

Arauco measures the fair value of the acquired company in the business combination achieved in each stage (“step acquisition”), recognizing the effects of remeasurement of previously held equity in the acquiree in the consolidated statements of profit or loss.

If the initial accounting for a business combination is not completed by the end of the reporting period in which the combination occurs, Arauco reports preliminary amounts for the items for which the accounting is incomplete. During the measurement period (no more than one year), these preliminary amounts are retrospectively adjusted, or additional assets or liabilities are recognized to reflect new information about facts and circumstances that existed at the acquisition date, if known, would have affected the amounts recognized at that date.

Business combinations that are under common control transactions are accounted using as a reference the pooling of interest. Under this method, assets and liabilities related to the transaction carry over the previous carrying values. Any difference between assets and liabilities included in the consolidation and the consideration transferred, is accounted in equity.

l) Investments in associates and joint arrangements

Associates are entities over which Arauco exercises significant influence, but not control. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

Joint arrangement is defined as an entity over which there is joint control, which exists only when the decisions about strategic of activities, both financial and operational, require the unanimous consent of the parties sharing control.

Investments in joint arrangements are classified as a joint venture or as a joint operation. A joint operation is a joint arrangement in which the parties that have joint control of the arrangement (i.e. joint operators) have rights to the assets and obligations for the liabilities, relating to the arrangement. A joint venture is a joint arrangement in which the parties that have joint control of the arrangement (i.e., participants in a joint venture) have rights to the net assets of the arrangement.

Investments in associates and joint ventures are accounted for using the equity method and are initially recognized at cost. Their carrying amount is increased or decreased to recognize the portion corresponding to the statement of profit or loss or to the statement of comprehensive income. Dividends received are recognized by deducting the amount received from the carrying amount of the investment. Arauco’s investment in associates includes goodwill (both net of any accumulated impairment loss).

The investments in joint operations are recognized through consolidation of assets, liabilities and results of operations in relation to Arauco's ownership percentage.

If the acquisition cost is lower than the fair value of the net assets of the associate acquired, the difference is recognized directly in statement of profit or loss in line other gains (losses).

Investments in associates and joint ventures are presented in the consolidated statement of financial position in the line item “Investments accounted for using equity method”.

Amounts in thousands of U.S. dollars, except as indicated

If Arauco’s share of losses of an associate or joint venture equals or exceeds its interest in the associate or joint venture, Arauco discontinues recognizing its share of further losses. After Arauco's carrying value in the investee is reduced to zero, additional losses are provided for, and a liability is recognized, only to the extent that Arauco has incurred legal or constructive obligations or made payments on behalf of the associate or joint venture. If the associate or joint venture subsequently reports profits, Arauco resumes recognizing its share of those profits only after its share of the profits equals the share of losses not recognized.

m) Intangible assets other than goodwill

After initial recognition, intangible assets with finite useful lives are carried at cost less any accumulated amortization and impairment losses.

Amortization of an intangible asset with a finite useful life is allocated over the asset’s useful life. Amortization begins when the asset is available for use, i.e., when it is in the location and condition necessary for it to be capable of operating in the manner intended by management.

(i) Computer software

Computer software licenses are capitalized in terms of the costs incurred to acquire and make them compatible with existing software. These costs are amortized over the estimated useful lives of the software.

(ii) Water rights, easements and other rights

This item includes water rights, easements and other acquired rights recognized at historical cost which have indefinite useful lives as there is no foreseeable limit to the period over which these assets are expected to generate future cash flows. These rights are not amortized, but are tested for impairment at least annually, or when there is any indication that the assets might be impaired.

(iii) Customers relationships

Correspond to the valuation over the time of the established relationship with customers, from the sale of products and services through its sales team. These relations will materialize in sales orders, which generate revenue and cost of sales. The useful life has been determined to be 15 years.

n) Goodwill

Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interest in the acquired company, and the fair value of the acquirer's previously held equity interest in the acquired company (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. If the total of consideration transferred, non-controlling interest recognized and previously held interest measured is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognized directly in the statements of profit or loss.

Goodwill is not amortized but tested for impairment on annual basis.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For purposes of impairment testing, goodwill in a business combination is allocated as of the acquisition date to the cash generating unit or a group of cash generating units expected to benefit from the synergies of the combination irrespective of whether other assets or liabilities of the acquired company are allocated to those units or group of units.

The goodwill generated on acquisitions of foreign companies, is expressed in the functional currency of such foreign company.

Goodwill recognized in subsidiaries Arauco Canada Ltd. and Arauco do Brasil S.A., generated on subsidiaries acquisitions whose functional currency is different from the functional currency of the parent company and presentation of these consolidated financial statements, are translated into U.S. dollars at the closing exchange rate.

o) Property, plant and equipment

Property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment. The cost includes expenditures that are directly attributable to the acquisition of the assets.

Subsequent costs, such as improvements and replacement of components, are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to Arauco and the cost of the item can be measured reliably. The carrying amount of the replaced part is derecognized from property, plant and equipment. All other repairs and maintenance costs are expensed in the period in which they are incurred.

Arauco capitalizes borrowing costs that are directly attributable to the acquisition, construction or production of qualifying assets as part of the cost of those assets, until the assets are ready for their intended use (See Note 12).

Depreciation is calculated by components using the straight-line method.

The useful lives of the items of property, plant and equipment is estimated according to the expected use of the assets. The residual values and useful lives of assets are reviewed and adjusted, if appropriate, annually.

p) Leases

Arauco applies IFRS 16 for recognizing leases in a manner consistent with contracts with similar features and akin circumstances.

At the beginning of a contract, Arauco assesses whether the contract is, or if it contains, a lease. A contract is, or contains, a lease if it transfers the right to control the use of a given asset for a certain period of time, in exchange for consideration.

As of the initial date for recording a lease, Arauco, as lessee, recognizes an asset by the right of use at cost.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

Unaudited consolidated financial statements

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

The cost of the asset for right of use comprises:

The amount of the initial measurement of the lease liability. This measurement is at present value of the payments for leases that have not been disbursed as of that date. Payments for leases are discounted using the incremental interest rate for financial borrowings;

Payments for leases performed prior to or as of the initiation date, minus the lease incentives that have been received;

The initial direct costs incurred by the lessee; and

An estimation of the costs to be incurred by the lessee when dismantling and eliminating the underlying asset, restoring the location where the same is located, or restoring the underlying asset to the condition required under the terms and conditions of the lease, unless such costs are incurred in order to produce inventories. The lessee assumes obligations stemming from such costs either at the commencement date, or as a result of having used the underlying asset during a specific period.

After the initial recognition date, Arauco, as lessee, recognizes its asset for right of use by applying the cost model, minus the accumulated depreciation and impairment losses, and adjusted for remeasurement of the liability for lease.

At the beginning, Arauco in the capacity of lessee, recognizes the lease liability at present value of the lease payments that have not been disbursed as of that date. Lease payments are discounted using the incremental interest rate for financial borrowings.

After the initial recognition date, Arauco, as lessee, recognizes a liability for leases by increasing the book value, so as to reflect the interest over the liability for lease, reducing the amount in order to reflect the payments for leases that have been performed and once again recognizing the book value, so as to reflect the remeasurement and also to reflect the essential fixed payments for leases that have been revised.

Arauco presents the assets by right of use in the consolidated statement of financial position and are further disclosed in Note 8. Likewise, lease liabilities are presented in the consolidated statement of financial position and further disclosed in Note 23.

IFRS 16 maintains substantially the accounting requirements of the lessor from IAS 17. Therefore, Arauco has continued to classify its leases as operational or financial, as the case may be.

Income from operating leases in which Arauco is the lessor are recognized on a straight-line basis during the term of the lease. Initial direct costs are added to the book value of the underlying asset and are recognized as expenses during the term of the lease on the same basis as the lease income. Leased assets are included within the statement of financial position, in property, plant and equipment. Arauco did not make adjustments with respect to assets that maintains as a lessor, as a result of IFRS 16 adoption.

When assets are leased under a financial lease, the present value of lease payments are recognized as financial accounts receivable. The difference between the gross receivable and the present value of such amount, is recognized as financial return on capital.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

Amounts in thousands of U.S. dollars, except as indicated

Arauco evaluates the economic nature of the contracts that grant the right to use certain assets, for the purposes of determining the existence of implied leases. In these cases, the Company separates, at the beginning of the contract and based on its relative reasonable values, payments and considerations associated with the lease, from the rest of the elements incorporated into the contract.

q) Biological assets

IAS 41 requires that biological assets, such as standing trees, are measured at fair value less cost to sell in the statement of financial position. Forestry plantations are accounted for at fair value less costs to sell, based on the presumption that fair values of these assets can be measured reliably.

The measurement of new forestry plantations made during the current year is made at cost, which corresponds to the fair value at that date. After twelve months, the valuation methodology used is that explained in the preceding paragraph.

Biological assets shown as current assets correspond to those forestry plantations that will be harvested in the short-term.

Biological growth and changes in fair value of forestry plantations are recognized in the line item “Other income” in the consolidated statements of profit or loss.

r) Income taxes

The tax liabilities are recognized in the consolidated financial statements based on the determination of taxable income for the year and calculated using the tax rates in force in the countries where Arauco operates.

Deferred income tax is recognized using liability method, on the temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated annual accounts. Deferred income tax is determined using tax rates contained in laws adopted as of the date of the financial statements and that are expected to be applicable when the related deferred tax asset is realized, or the deferred income tax liability is settled.

Deferred taxes are recognized in accordance with the standards established in IAS 12 - Income Tax.

The goodwill arising on business combinations does not give rise to deferred tax.

The deferred tax assets and tax credits are generally recognized for all deductible temporary differences to the extent that it is probable that future taxable profit will be available against which those deductible temporary differences can be utilized.

s) Provisions

Provisions are recognized when the Company has a present obligation, legal or constructive, as a result of past events, under which, it is probable that an outflow of resources will be required to settle the obligation; and when a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the end of the reporting period.

t) Revenue recognition

Revenues are valued at fair value of the consideration received or to be received, derived from them. Arauco analyses and takes under consideration all relevant facts and circumstances to apply the five-step model established under IFRS 15 to customer contracts: (i) identify the contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction price, and (v) recognize revenue. Additionally, Arauco evaluates the incremental costs of obtaining a contract and the costs incurred to comply with a contract. Arauco recognizes revenues when the steps established in IFRS have been satisfactorily complied with.

Accounts receivable are recognized when control over goods or services has been transferred to the customer, because at this point of the time collection is unconditional and the passage of time is only needed to receive payment.

(i)

Revenue recognition from the sale of goods

Revenue from the sale of goods is recognized when Arauco has transferred to the buyer the significant risks and rewards of ownership of the committed goods, when the amount of revenue can be reliably measured, when Arauco does not retain any managerial involvement over the goods sold and when it is probable that the economic benefits associated with the transaction will flow to Arauco and the costs incurred in respect of the transaction can be measured reliably. Revenue from the sale of goods are recognized when there is no obligation unsatisfied that could affect the customer’s acceptance of the product. The delivery is effective when the products are sent to the specific location, the risks of obsolescence and loss have been transferred to the customer and when Arauco has objective evidence that all acceptance criteria have been satisfied.

Sales are recognized in terms of the price agreed to in the sales contract, less any volume discounts and estimated product returns at the date of the sale. There is no significant financing component given that receivables from sales are collected within a short period, which is in line with market practices.

The structure for recognizing revenue from export sales is based on the 2010 Incoterms, which are the official rules for the interpretation of commercial terms issued by the International Chamber of Commerce.

The main Incoterms used by Arauco are the following:

“CFR (Cost and freight)”, where the company bears all costs including main transportation, until the products arrives at its port of destination. The risk is transferred to the purchaser once the products have been loaded onto the vessel, in the country of origin.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

Unaudited consolidated financial statements

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

“CIF (Cost Insurance & Freight)”, where the Company organizes and pays for external freight services and some other expenses. Arauco is no longer responsible for the products once they have been delivered to the ocean carrier company.

(ii) Revenue recognition from rendering of services

Revenue from the rendering of services is recognized as long as the performance obligation have been satisfied.

Revenue is recognized considering the stage of completion of the transaction at the date of the reporting period, when Arauco has the enforceable right of payment from the rendering of the services.

There is no significant financing component, given that sales are made with a reduced average collection period, which is in line with market practice.

Arauco mainly provides power supply services which are transacted principally in the spot market of the Sistema Eléctrico Nacional (SEN) (“National Electrical System”). According to current regulations, the prices on that market called “Marginal Costs” are calculated by the Coordinador Eléctrico Nacional (CEN) (“National Electrical Coordinator”) and are generally recognized in the period in which the services are rendered.

Electrical power is generated as a by-product of the pulp and wood process and is a complementary business to it, which is initially supplied to the group’s subsidiaries and any surplus is sold to the SEN.

Arauco provides other non-core services such as port services and pest control whose revenues are derived from fixed price service contracts are recognized considering the stage of completion of the services rendered at the date of reporting, generally during the period of the service contract on a straight-line basis over the term of the contract.

Revenues from reportable segments mentioned in Note 24 are measured in accordance with the policies indicated in the preceding paragraphs.

Revenues from inter-segment sales (which are made at market prices) are eliminated in the consolidated financial statements.

u) Minimum dividend

Article No. 79 of the Chilean Corporations Law states that, unless otherwise unanimously agreed by the shareholders, corporations must distribute annually at least 30% of net income for the current year as cash dividend to shareholders determined in proportion to their shares or in the proportion established in the by-laws for preferred shares, if any, except where necessary to absorb accumulated losses from prior years.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

Unaudited consolidated financial statements

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

The current policy is that an amount equivalent to the 40% of the distributable net income for each fiscal year will be distributed as dividends. Nevertheless, the Board of Directors may decide to distribute and pay dividends to the shareholders, to the extent that it expects the year to finalize with positive results and that the Company’s liquidity allows such distribution and payment.

v) Earning per share

Basic earnings per share are calculated by dividing the net profit for the period attributable to the parent company by the weighted average number of ordinary shares outstanding during the period, excluding the average number of shares in the Company held by a subsidiary, if such circumstance exists. Arauco has not performed any type of transaction with a potential dilutive effect that would cause diluted earnings per share to be different from basic earnings per share.

w) Impairment

Non-financial assets

The recoverable amount of property, plant and equipment and other long-term assets with finite useful lives are measured whenever there are any circumstances indicating that the assets have to recognize an impairment loss. Among the circumstances to consider as evidence of impairment are significant declines in the assets’ market value, significant adverse changes in the technological environment, obsolescence or physical damages of assets and changes in the manner in which the asset is used or expected to be used). Arauco evaluates at the end of each reporting period whether there is any evidence of the indications above mentioned.

A previously recognized impairment loss is reversed if there has been a change in the estimates used to determine the recoverable amount however a reversal of an impairment loss shall not exceed the carrying amount that would have been determined (net of amortization or depreciation) had no impairment loss been recognized for the asset in prior years.

For the purposes of assessing impairment losses, assets are grouped at the lowest level for which there is identifiable cash flows separately for each cash-generating unit. Non-financial assets, other than goodwill, which had recognized an impairment loss, are reviewed at the end of each reporting period whether there are any circumstances indicating that an impairment loss previously recognized may no longer exists or has decreased.

“Cash-generating units” are the smallest identifiable groups of those cash inflows that are largely independent of the cash inflow from other assets or groups of assets.

Goodwill

Goodwill and intangible assets with indefinite useful life are tested annually for impairment or whenever circumstances indicate it. The recoverable amount of an intangible asset is the higher of its fair value less costs to sell and its value in use. An impairment loss is recognized whenever the carrying amount exceeds the recoverable amount.

CELULOSA ARAUCO Y CONSTITUCION S.A. AND SUBSIDIARIES

Unaudited consolidated financial statements

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

A cash-generating unit, for which goodwill has been allocated, is tested for impairment annually or more frequently when there are circumstances indicating that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to other assets pro rata based on the carrying amount of each asset in the unit. Any impairment loss of goodwill is recognized directly in the consolidated statement of profit or loss. An impairment loss recognized for goodwill is not reversed in subsequent periods.

Goodwill is allocated to cash-generating units for impairment testing purposes. The allocation is made between cash-generating units or groups of cash generating units expected to benefit from the synergies of the combination.

Financial assets

At the end of each reporting period, an assessment is performed in order to identify whether there is any objective evidence that a financial asset or a group of financial assets may have been impaired.

An allowance for doubtful accounts is established based on a measurement of expected losses using a simplified approach.

The allowance for doubtful accounts is measured as the difference between the carrying amount of receivables and the present value of estimated future cash flows. The carrying amount of the receivable is reduced through the use of the allowance. If the impairment loss decreases in later periods, it is reversed either directly or by adjusting the provision for doubtful accounts, with effect in profit or loss.

x) Employee benefits

Arauco constitutes labor obligations for severance payable in all circumstances for certain of its employees with at least 5 years of work in the Company, based on the terms of the staff’s collective and individual bargaining agreements.

The related provision is an estimate of the years of service to be recognized as a future labor obligation liability, in accordance with contracts between Arauco and its employees and pursuant to actuarial valuation criteria for this type of liability. This post-employment benefit is considered a defined benefit plan.

The main factors considered for calculating the actuarial value of severance obligation for years of service are employee turnover, salary increases and life expectancy of the workers included in this benefit.

Actuarial gains and losses are recognized in other comprehensive income in the year they are incurred.

These obligations are related to post-employee benefits in accordance with current standards.

This obligation is presented in line item “Trade and other current payables” in the consolidated statements of financial position.

z) Recent accounting pronouncements

a) Standards, interpretations and amendments that are mandatory for the first time for annual periods beginning on January 1, 2024:

Amendments and improvements	Content	Mandatory application for annual periods beginning on or after
IAS 1	Presentation of financial statements Clarifies that liabilities are classified as current or non-current depending on the rights that exist at the end of the reporting period. The classification is not affected by the entity's expectations or events after the reporting date (for example, the receipt of a waiver or a breach of agreement). The amendment also clarifies what IAS 1 means when it refers to the "settlement" of a liability. The amendment should be applied retrospectively in accordance with IAS 8.	January 1, 2024

IAS 1	International tax reform - pillar two model rules These amendments clarify how conditions with which an entity must comply within twelve months after the reporting period affect the classification of a liability. The amendments also aim to improve information an entity provides related to liabilities subject to these conditions.	January 1, 2024

IFRS 16	Leases on sale and leaseback These amendments include requirements for sale and leaseback transactions in IFRS 16 to explain how an entity accounts for a sale and leaseback after the date of the transaction. Sale and leaseback transactions where some or all the lease payments are variable lease payments that do not depend on an index or rate are most likely to be impacted.	January 1, 2024

IAS 7 and IFRS 7	Supplier finance arrangements These amendments require disclosures to enhance the transparency of supplier finance arrangements and their effects on a company’s liabilities, cash flows and exposure to liquidity risk.	January 1, 2024

The adoption of the standards, amendments and interpretations described in the table above have not had a significant impact on Arauco’s consolidated financial statements during its initial application period.

NOTE 5. CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand, bank checking account balances, time deposits and mutual funds. These are short-term highly liquid investments that are readily convertible to known amounts of cash and are subject to an insignificant risk of changes in value.

The investment objective of time deposits is to maximize the amounts of cash surpluses in the short-term. These instruments are permitted under Arauco’s Investment Policy which allows investing in fixed income securities. These instruments have a maturity of less than three months from the date of acquisition.

Arauco invests in local and international mutual funds in order to maximize the returns of cash surpluses denominated in Chilean pesos or in foreign currencies such as U.S. dollars or Euros. These instruments are permitted under Arauco’s Investment Policy.

As of the date of these interim consolidated financial statements, there are no amounts of cash and cash equivalents with restrictions on use.

(*) Includes tax effect due to inflation adjustment on Argentine tax bases.

(**) This line mainly includes the tax effect generated by the exchange difference in the conversion of tax bases with local currency other than the functional currency.

Arauco has evaluated the potential impact derived from the implementation of the so-called “GloBE or Pillar 2 Rules”, whereby multinational groups are required to pay a minimum effective tax rate of 15%.

To date, this regulation has not been adopted in Chile (the jurisdiction where Arauco’s parent company is based), but it has been adopted in other jurisdictions where Arauco operates, making it necessary to estimate the prospective impact of its application following its entry into force (January 1, 2024).

In view of the fact that Arauco has subsidiaries in the United Kingdom and the Netherlands, jurisdictions where the relevant legislation has already been enacted, estimates have been made to determine the potential impacts on the taxes to be paid by Arauco starting in 2024. As of the date of these financial statements, it is estimated that this legislation will have no impact whatsoever, therefore, no expenses (income) have been recorded for current taxes related to the Pillar 2 income tax. However, due to the complexity of this new legislation, it is possible that these estimates may be modified during the current year.

(*) Period 2024, includes depreciation expenses generated by property, plant and equipment classified as assets held for sale, see note 22.

Depreciation charged to profit or loss statement differs from the movement of the period for Property, Plant and Equipment. This is mainly due to the periodic cost processes in which a portion of the depreciation charge remains in Inventories. Furthermore, this deviation is also affected by the conversion differences corresponding to companies that use a functional currency other than U.S. dollars.

The useful lives of property, plant and equipment are estimated based on the expected use of the assets. The average useful lives by asset class are as follow:

	Years of Useful Life (Average)

Unaudited consolidated financial statements

March 31, 2024

Amounts in thousands of U.S. dollars, except as indicated

According to significant restrictions on the ability of subsidiaries to transfer funds to Arauco, in the form of cash dividends or repayment of borrowings and/or advances, we state the following:

Long-term debt with related entities - mutual agreement with Arauco Argentina S.A.

On June 5, 2017, Arauco signed a mutual agreement with its subsidiary Arauco Argentina S.A., pursuant to which this subsidiary received an amount of U.S.$ 250,000,000, which accrues an interest at the SOFR interest rate for 180 days plus a fixed spread of 5.20% and an adjustment of 0.42826% resulting from the replacement of LIBOR rates in dollars with SOFR rates (this according to the “Selections and Recommendations” of the “Alternative Reference Rates Committee” or ARRC), with payments every six months on June 1 and December 1 of each year.

Since 2020, the Central Bank of the Argentine Republic (BCRA) established certain foreign exchange controls, preventing Arauco Argentina S.A. from repaying the amount of ThU.S.$160,000 owed under the mutual agreement described above which matured on June 1, 2022.

On July 14, 2022, Arauco Argentina S.A. paid ThU.S.$ 6,000 of the amount owed under the mutual agreement described above, remaining to pay ThU.S.$ 154,000 as of the date of these interim consolidated financial statements.

The acquired companies are Taurion S.A., Taurion Asociación Agraria de Responsabilidad Limitada, Monte Fresnos S.A. and Monte Fresnos Asociación Agraria de Responsabilidad Limitada.

On September 13, 2023, Arauco, through its United Kingdom investment company Arauco Ventures Ltd., acquired 51.1278% of the company TreeCo, Inc. in the United States.

At the closing of these financial statements the amount paid was ThU.S.$ 11,000.

Of the total of goodwill, ThU.S.$ 40,672 (ThU.S.$ 40,726 as of December 31, 2023) were generated by the acquisition of “Flakeboard” (currently Arauco Canada Ltd.), a company that, directly and/or through its subsidiaries, possesses and operates 7 panel plants, for which Arauco acquired and paid, on September 24, 2012, the price of ThU.S.$ 242,502 for the 100% interest ownership.

The recoverable amount for Flakeboard’s cash generating unit was determined based on the calculations of its value in use, and this calculation was made using cash flow projections covering a 7-year term, a period time, which is considered to represent the cyclicality of the business performance, applying a nominal discount rate of 7% which reflects current market assessments for the wood products segment in North America.

Due to the investment in panel plant in Pien, Brazil, there is a goodwill of ThU.S.$ 13,985 (ThU.S.$ 14,433 as of December 31, 2023).

The recoverable amount for the Pien mill’s cash generating unit was determined based on the calculations of its value in use, and this calculation was made using cash flow projections covering a 5-year term based on the operational plan approved by the Administration, applying a 7.4% nominal discount rate that reflects current evaluations for the panel segment in Brazil.

As of March 31, 2024 and December 31, 2023, the carrying value of the goodwill of the plants did not exceed their recoverable value.

In the alternative, it claims (a) CLP$11,189,270,050 (equivalent to ThU.S.$ 12,757 as of March 31, 2024), for actual damages; (b) CLP$ 11,189,270,050 monthly during the entire course of the trial, until the termination of the contract is declared in the final ruling, for loss of profits, and (c) CLP$5,000,000,000 (equivalent to ThU.S.$ 5,700 as of March 31, 2024) for moral damages.

On August 28, 2018, the claim was served on all the defendants, with the exception of Servicios Logísticos Arauco SpA.

Five years after the lawsuit was filed, on September 7, 2023, ASODUCAM amended its claim, withdrawing it with respect to Servicios Logísticos Arauco SpA.

On October 6, 2023, two motions to declare the abandonment of proceedings were filed: one by Celulosa Arauco y Constitución S.A. and Maderas Arauco S.A., and the other by Forestal Arauco S.A. These motions were dismissed on November 24, 2023. These resolutions were then challenged by motions to reconsideration, with appeals. The motions for reconsideration were dismissed on December 12, 2023, and the direct appeals were admitted on that same date, forwarding the case to the Court of Appeals of Talca (Docket Nos. C-2258-2023 and C-2259-2023). On February 1, 2024, both appeals were joined and the case is now ready to be heard by the appellate court.

In case No. 31.570-2022, processed before the Supreme Court, reviewing a cassation appeal on the merits (recurso de casación en el fondo), which pertains to the same facts of this trial under No. C-757-2018, and in which case the litigating parties Asoducam et al, and Maderas Arauco S.A. and Celulosa Arauco y Constitución S.A., the parties reached a settlement, as evidenced by the minutes dated November 22, 2023. Pursuant to this settlement, which did not imply a payment or disbursement for Arauco, the parties agreed to the withdrawal of the claim by Asoducam, which should have materialized no later than January 22, 2024. To date, this has not occurred, which is why, on January 29, 2024, Maderas Arauco S.A. and Celulosa Arauco y Constitución S.A. informed the Judge of Constitución, in case C-757-2018, of the abandonment by Asoducam, as agreed in the minutes.

On January 31, 2024, the court decided not to give a rise to the last presentation. An appeal for reconsideration and subsidy appeal was filed against said resolution, which is being processed and in a state of relation before the I. Court of Appeals of Talca.

On February 5, 2024, Celulosa Arauco y Constitución S.A. and Maderas Arauco S.A. formally objected to a transaction exception and, in subsidy, answered the lawsuit. For its part, Forestal Arauco S.A. directly answered the lawsuit presented by ASODUCAM.

As of this date, the discussion phase of this case has concluded and the settlement hearing was held on April 18, 2024. The court must now initiate the evidentiary stage of this case, which is still pending.

Forestal Arauco S.A.

On July 7, 2015 Inversiones Forestales Los Alpes Limitada and Forestal Neltume-Carrasco S.A. filed a claim against Forestal Arauco S.A. before the Civil Court of Angol (C-502-2015), in which they request that Forestal Arauco S.A. restitute the material possession of 1,855.9 hectares, which would be part of their property "Resto del Fundo Los Alpes", which would have an area of approximately 2,700 hectares. Likewise, they requested that it be declared that the property is the exclusive domain of the actors, the restitution of the civil and natural fruits, in addition to the deteriorations that the property would have experienced, with litigation costs.

On May 29, 2019, the lawsuit was answered, and the counterclaim of the acquisitive prescription was filed.

On September 1, 2020, the court received the case. Moreover, the resolution was notified on August 30, 2022, along with the resolution to reactivate the discovery period.

On September 2, 2022, the company filed a motion for abandonment of proceedings, the resolution of which is still is pending.

Considering that the Company's position is supported by solid legal arguments, there is a reasonable margin of obtaining a favorable result for the Company and that is why, as of March 31, 2024, Arauco has not established any provision for this contingency.

Arauco Argentina S.A.

Pursuant to law No. 25,080, the former Secretary of Agriculture, Livestock, Fishing and Foodstuffs, the enforcement agency referred to in the law approved, by Res. No. 952/2000, the forestry and industrial-forestry projects submitted by Arauco Argentina S.A. In the context of these projects, the Company afforested: 1) 4,777 hectares during 2000, in observance of its committed yearly plan; and 2) 23,012 hectares between 2000 and 2006 as a part of the multi-year afforestation plan. Likewise, a sawmill was built with installed capacity to produce 250,000 m3 of sawn timber per year.

On January 11, 2001, Arauco Argentina S.A. submitted an expansion for the approved industrial-forestry project. The expansion was approved via Res. No. 84/03 issued by the former Secretary of Agriculture, Livestock, Fishing and Foodstuffs. In accordance with the assumed obligations, the Company built a MDF board (panels) plant and afforested 8,089 hectares between 2001 and 2006.

Additionally, the Company has filed yearly forestry plans between years 2007 and 2021 for its local operations in the provinces of Misiones and Buenos Aires.

On March 25, 2019, the Secretary of Agriculture, Livestock and Fishing approved the resolution No. 2019-55-APN-SECAGYP#MPYT, approving the annual forestry plan for 2007. In addition, said organism through the resolution No. 2019-114-APN-SECAGYP#MPYT approved the annual forestry plan for 2009 on June 12, 2019, and through the resolution No. 2019-228-APN-SECAGYP#MPYT approved the annual forestry plan for 2008 on November 29, 2019. For this reason, Arauco Argentina S.A. may compute the exemption in the income tax related to the forest appraisal on the plantations to be harvested from the lands included in those plans as from the 2019 period.

In March 2005, Note No. 145/05 of the Subsecretary of Agriculture, Livestock and Afforestation suspended the benefit that exempted Arauco Argentina S.A. from paying export duties under Law No. 25,080. This measure is currently under discussion by the Company. On November 8, 2006, the V Chamber of the National Appeals Court for Adversarial Administrative and Federal Matters issued a ruling ordering Arauco Argentina S.A. to continue to enjoy an exemption from paying the exportation duties, in the same manner and scope it had prior to the suspension ordered by Note No. 145/05, if the clearance of merchandise is performed pursuant to the guarantee regime established in article 453, subsection a) of the Customs Code, for the exempted tax obligation. The judicial measure became effective beginning in March of 2007 by collateralization through the granting of bond (caution) policies for each shipment permits exempted from payment of export duty. The company maintains an assignment of funds equivalent to $ 23,821 for guaranteed export duties between 2007-2015, which appears under long-term provisions. Additionally, the Company filed a restitution claim for a total amount of ThU.S.$ 6,555, plus interest accrued from the service of the claim, corresponding to export duties between March 2005 and March 2007, as a result of the application of Note 145/05 issued by the Undersecretary of Agriculture, Livestock and Afforestation. The Company’s claim is being heard under case file No. 21830/2006 before the Federal Contentious Administrative Court No. 4. On October 28, 2019, a judgment of first instance was issued in said case, rejecting the claim and imposing the litigation costs on Arauco. Against that judgment, the Company filed an appeal and expressed the corresponding arguments in December 2019. On June 15, 2022, the Chamber of Appeals confirmed the judgement of first instance. On July 1, 2022, Arauco Argentina filed the Federal Extraordinary Appeal before the Supreme Court of Justice. The Chamber admitted the appeal lodged by Arauco regarding the federal matter of the litigation; however, the grounds pertaining to arbitrariness were dismissed. Arauco filed a direct complaint before the Supreme Court, seeking for the higher court to broaden its examination of the case and also address such argument. Currently, both proposals are in process.

On the other hand, Arauco Argentina S.A. currently has a guarantee at an amount of $ 435,952,315 Argentine pesos (ThU.S.$ 508 as of March 31, 2024) in favor of the Secretary of Agriculture, Livestock and Fishing.

Arauco Argentina S.A. believes that it has complied with all of the obligations imposed upon it by the system set forth under Law No. 25,080.

Arauco do Brasil S.A.

1) On November 8, 2021, the Federal Reserve of Brazil contested the amortization of goodwill resulting from acquisitions of Placas do Paraná, Tafibrás, Tafisa (now, Arauco do Brasil S.A.) y Dynea Brasil S.A. The company presented the appropriate administrative defense at that time.

On July 20, 2015, Arauco do Brasil was notified of the first administrative level decision, which partially ratified the sanction. Faced with this, Arauco filed an appeal ("Voluntary Appeal") before the CARF (Conselho Administrativo de Recursos Fiscais do Brasil), which is the second administrative level.

On May 16, 2017, the CARF reduced the contingency for Arauco, because it upheld some of the Company's arguments, but maintained other charges. On September 27, 2018, Arauco was notified of the CARF's decision, so it filed a motion for clarification, seeking to have some points of the decision clarified. On January 25, 2019, CARF declared that there would be no clarifications or omissions to be provided, so the deadline to file the last administrative appeal ("Special Appeal") commenced. This appeal was filed before the CARF Superior Chamber of Fiscal Resources (“CSRF”) on February 11, 2019, reiterating the Company's defense allegations regarding the upheld issues and charges.

On August 28, 2020, the Company was served with an intermediate decision in Grievance of Instrument, issued by CARF that divided the claim into two parts, one at the administrative level and the other one at the judicial level:

I – The administrative level fine(deductibility of interest and isolated fine of 50%) whose estimated amount of R$34.5 million (equivalent to ThU.S.$ 6,896 as of March 31, 2024). Pursuant to these requirements on March 27, 2023, Arauco do Brasil adhered to the government program of reduction of fiscal litigation which permits a reduction of the 65% of the entire amount of the debt through the payment of the 35% of the debt in two ways: (a) payment in cash of the 30%, totaling R$3.7 million (ThU.S.$ 734 as of March 31, 2024) and (b) payment of 70% of fiscal losses, totaling R$8.6 million (ThU.S.$ 1,714 as of March 31, 2024).

Subsequently, Arauco do Brasil performed the payment in cash and also the offset with tax losses. Notwithstanding the foregoing, the Federal Reserve of Brazil (Brazilian tax service) must confirm Arauco do Brasil's compliance with the program, thus closing the part of the case which was being reviewed before an administrative venue.

II – Part of the case that remained in a judicial venue (contractual expenses deducted in the purchase of Tafisa Brasil; interest and legal expenses on debts in the amnesty program; Imposto de Renda Pessoa Jurídica, or “IRPJ”, and lower Contribuição Social sobre o Lucro Líquido, or “CSLL” whose updated estimated amount is R$ 42,167,507 (ThU.S.$ 8,428 as of March 31, 2024). Arauco do Brasil filed the Tax Debt Annulment Action.

On March 9, 2023, the trial court issued a judgment that was partially favorable to Arauco do Brasil, upholding the aforementioned claims, and thus setting aside the portion of the debt corresponding to R$ 26,554,677 (ThU.S.$ 5,307 as of March 31, 2024). However, the judgment rejected the claim related to interest and legal expenses on debts under the amnesty program, which estimated amount is R$ 15,612,831 (ThU.S.$ 3,120 as of March 31, 2024).

On May 29, 2023, the Federal Reserve filed an appeal seeking the revocation of the judgment in the section that was favorable to Arauco, while, on June 26, 2023, Arauco also filed an appeal, but seeking the ratification of the judgment regarding interest and legal expenses on debts in the amnesty program. Arauco filed its counter-arguments to the Appeal of the National Treasury and is currently awaiting the filing of counter-arguments by the National Treasury to subsequently send the case to the Court for an appellate judgment.

After the submission of counter-arguments by both parties, on July 18, 2023 the case was referred to the court for an appellate trial. The case is currently awaiting trial in court.

2) In 2013, a service provider instituted a civil lawsuit against us seeking compensation for damages allegedly caused by Arauco’s unilateral termination of its contract in connection with the implementation of the MDF 2 line of the Jaguariaiva mill. On November 01, 2021, the Civil Court of Curitiba issued its ruling, ordering Arauco to pay to the service provider an amount of ThR$ 84,000 (ThU.S.$ 16,789 as of March 31, 2024) in consideration of the alleged damages borne by the service provider during the course of the services contracts and as a result of its early termination by Arauco.

After the judgment, we were summoned and on March 8, 2022 we filed an Appeal, and the opposing party was summoned to present arguments on our appeal and filed the petition on April 11, 2022, also appealing the judgment.

In April 2023, a favorable ruling was handed down in our Appeal and we succeeded in annulling the judgment so that the case could return to its origin. This annulment ruling will also affect the expert evidence, which will have to be produced again. As a result, the provision of R$ 42,945,528 (ThU.S.$ 8,583 as of March 31, 2024) was fully reversed.

In May 2023, the contractor company filed a Motion for Clarification presenting alleged omissions, in an attempt to preserve the decision or at least the evidence already produced. Review of these remedies is currently pending. In July 2023, the appeal was dismissed.

In August 2023, the contractor filed a Special Appeal before the Higher Court of Justice, in an attempt to reverse the decision in favor of Arauco.

In October 2023, the special appeal was rejected. In November 2023, the contractor firm lodged an appeal, seeking admissibility.

NOTE 20. BIOLOGICAL ASSETS

Biological assets comprise forestry plantations, mainly radiata and taeda pine, and to a lesser extent eucalyptus. The plantations are located in Chile, Argentina, Brazil and Uruguay.

As of March 31, 2024, Arauco had a total surface of 1.76 million hectares of which 976 thousand hectares are used for forestry planting, 512 thousand hectares are native forest, 114 thousand hectares are used for other purposes and 158 thousand hectares not yet planted. Lands corresponding to native forest, lands used for other purposes and lands not yet planted are presented in property, plant & equipment, Forest plantations are presented in Biological Assets.

For the three-months period ended March 31, 2024, the production volume of logs totaled 5.1 million m3 (4.3 million m3 as of March 31, 2023).

Measurements of fair value of Arauco’s biological assets are classified as Level 3, due to the fact that inputs are not observable. However, this information reflects the assumptions that market participants would use in pricing the asset, including assumptions about risk.

These unobservable inputs were developed using the best information available and includes internal data from Arauco. These unobservable inputs can be adjusted if the available information indicates that other market participants would use different information or there is something specific in Arauco that is not available to other market participants.

The main considerations in determining the fair value of biological assets include the following:

- Arauco uses discounted expected future cash flows of its forest plantations, which are based on a harvest projection date for all existing plantations.

- Current forestry plantations are projected based on a net volume that will not decrease, with a minimum growth equivalent to the current supply demand.

- Future plantations are not considered.

- The harvest of forestry plantations supplies raw materials for all other products that Arauco produces and trades. By directly controlling the development of forests that will be processed, Arauco ensures high quality timber for each of its products.

- Expected cash flows are determined in terms of harvest and expected sale of forestry products, associated with the demand from the Company’s own industrial centers and sales to third parties at market prices. Sales margin of the different products that are harvested in the forest is also considered in the valuation. The changes in the value of the plantations pursuant to the criteria defined above are accounted for in the results for the period, as established in IAS 41. These changes are presented in the interim consolidated statements of profit or loss under the line item other income per function, which as of March 31, 2024 amounted to ThU.S.$ 4,911 (ThU.S.$ 52,622 as of March 31, 2023). The appraisal of biological assets resulted in a greater cost of the lumber sold in comparison to the real incurred cost, which is presented included in the cost of sales which as of March 31, 2024 amounted to ThU.S.$ 66,407 (ThU.S.$ 60,076 as of March 31, 2023).

- Forestry plantations are harvested according to the needs of Arauco’s production plants.

- The discount rates used are 7.0% in Chile, 8.3% Brazil, 22.6% in Argentina and 9% in Uruguay.

- It is expected that prices of harvested timber are constant in real terms based on market prices.

- Cost expectations with respect to the lifetime of the forests are constant based on estimated costs included in the projections made by Arauco.

- The average crop age by species and country is:

	Chile		Argentina		Brazil		Uruguay
Pine		24		15		15		-
Eucalyptus		12		10		7		10

The following table sets forth changes in fair value of biological assets considering variations in significant assumptions considered in calculating the fair value of the assets:

		ThU.S.$
Discount rate	0.5		(110,889	)
	-0.5		118,132
Margins (%)	10		456,106
	-10		(456,106	)

The significant unobservable input data used in the measurement of the fair value of biological assets are discount rates and sales margins of the different products that are harvested from the forest. Increases (decreases) in any of these input data considered in isolation would result in a smaller or greater fair value measurement.

The adjustment to fair value of biological assets minus sale costs is recorded in the interim consolidated statements of profit or loss, under the line item other income or other expenses, depending on whether it corresponds to profits or losses.

Forestry plantations classified as current biological assets are those to be harvested and sold within twelve months after the reporting period.

The Company has contracted fire insurance policies for its forestry plantations, which in conjunction with the Company’s resources, allow risks to be minimized.

As of the date of these interim consolidated financial statements, there are no committed disbursements for the acquisition of biological assets.

Detail of biological assets pledged as security

As of March 31, 2024, there were no forestry plantations pledged as security.

Detail of biological assets with restricted ownership

As of the date of these interim consolidated financial statements, there are no biological assets with restricted ownership.

No significant government grants have been received.

NOTE 21. ENVIRONMENTAL MATTERS

Environment management

For Arauco, sustainability means management strategy. This strategy incorporates values, commitments and standards, that together with the adoption of best practices as well as the use of the latest available technologies, seek to continuously improve the Company’s environmental management. It is the environmental department and each of its specialists that ensure these guidelines are met and are put into practice in everyday company operations.

All Arauco’s production units have certified environmental management systems, which reinforce the Company’s commitment to environmental performance and ensure the traceability of all raw materials used.

Arauco uses several supplies in its productive processes such as wood, chemical products, and water, etc., which in turn produce liquid and gas emissions. As a way to make the Company’s environmental management more efficient, significant progress has been made to reduce consumption and emissions.

Environmental investments have been made related to the control of atmospheric emissions, process improvements, water and waste management, as well as effluent treatment, in order to improve the environmental performance of all Arauco’s business units.

These investments are reflected in the interim consolidated financial statements as property, plant and equipment when they refer to disbursements in major works executed and are reflected in Expenses when they refer to improvements or management not directly associated with investment projects.

Detail information of disbursements related to the environment

As of March 31, 2024 and December 31, 2023 Arauco had made and / or had committed the following disbursements in major environmental projects:

NOTE 22. NON-CURRENT ASSETS HELD FOR SALE

On December 20, 2023, Arauco entered into a share purchase agreement (“SPA”). Pursuant to this agreement, Arauco, along with its subsidiary Inversiones Arauco Internacional Limitada (“IAIL”, and jointly with Celulosa Arauco, the “Sellers”), agreed to sell to a company specially incorporated for such purpose and designated by the Brazilian company Klabin S. A. (the “Buyer”) all of the shares and interests that the Sellers directly hold in Arauco Florestal Arapotí S.A. and Arauco Forest Brasil S.A., and indirectly hold in Empreendimentos Florestais Santa Cruz Ltda. and Florestal Vale do Corisco S.A. (jointly, the “Brazilian Forestry Companies”), which own assets mainly in the state of Paraná, Brazil.

The assets included in the sale are all the shares and interests in these Brazilian forestry companies, except for Florestal Vale do Corisco S.A., where the Sellers indirectly own 49% of the latter’s shares of this associate.

The eucalyptus and pine forest plantations included in the transaction span approximately 85,000 hectares. Moreover, it should also be noted that the sale of shares and interests does not extend to the industrial assets related to the panel mills in Brazil, nor to other forestry assets located mainly in the state of Mato Grosso do Sul, Brazil, which are related to an industrial project to subsequently build a pulp mill, known as “Project Sucuriú.”

The total price of the agreed purchase amounts to the sum of ThU.S.$ 1,160,000, payable on the closing date of the transaction (the “Closing”). The purchase price is subject to customary adjustments in this type of transactions, depending on factors such as working capital, net debt and the amount of standing timber of pine and eucalyptus of the Brazilian forestry companies, existing at the Closing. Furthermore, the Closing would be subject to the fulfillment of the usual conditions precedent for this type of operation, among which is the authorization by the Brazilian antitrust authorities (Consejo Administrativo de Defensa Económica or “CADE”).

It has been preliminarily estimated that, should the transaction close, it will have a positive effect on earnings for 2024 of approximately US$ 130 million after taxes (plus the reverse of the deferred tax recorded in 2023 and mentioned later in this Note), resulting from the sale of the shares and interests in the Brazilian forestry companies.

Given the above conditions and effective as of March 31, 2024, the assets and liabilities associated with this operation have been reclassified to Assets and Liabilities held for sale, in accordance with IFRS 5.

Prior to the reclassification to held for sale and as prescribed by IFRS 5, Arauco assessed whether at that date it was necessary to conduct an adjustment to bring such assets to the lower of their book value and realizable value, resulting in no adjustment to be recorded (the value of the sale is higher than the book value).

The following table sets forth information on the main types of non-current assets and liabilities held for sale:

These deferred taxes reflect the difference between the financial book value and tax value of the companies to be sold, which were not previously recorded in accordance with IAS 12. This value is comprised of a credit to earnings for 2024 of ThU.S.$3,099 (charge of ThU.S.$57,110 as of December 31, 2023) and a credit to conversion reserves of ThU.S.$2,053 (ThU.S.$135,171 as of December 31, 2023) (see note 6). These deferred taxes will be subsequently allocated to the tax result that will be generated at the closing of the sale of the aforesaid investments.

23.2 Fair value hierarchy of financial assets and liabilities

The assets and liabilities measured at fair value in the interim consolidated statements of financial position as of March 31, 2024 and December 31, 2023, have been measured based on the valuation methodologies provided in IFRS 13. The methodologies applied for each financial instrument are classified according to their hierarchy as follows:

- Level 1: Securities or quoted prices in active markets for identical assets and liabilities

- Level 2: Inputs other than quoted prices included within Level 1 that are observable for the assets or liabilities, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and

- Level 3: Inputs for the assets or liabilities that are not based on observable market data (unobservable inputs).

23.3 Explanation of the valuation of financial instruments.

Cash and cash equivalent and accounts receivable

The carrying amount of accounts receivable, cash and cash equivalents (including mutual funds), and other financial assets and liabilities approximate their fair value due to the short-term nature of such instruments.

Derivative financial instruments

Arauco's current derivatives are valued under the cash flow discount method. These flows are discounted at the rate applicable according to the transaction’s and counterparties’ risk, using an internal methodology based on the information obtained from Bloomberg.

Given that our cross-currency swaps correspond to future flows in U.F., U.S. dollars and Euros, Arauco calculates the current value of such flows by using the U.F. zero coupon curve, dollar zero coupon and the Euro zero coupon.

The fair value of the interest rate swap contracts is calculated by reference to the rate differential between the agreed upon rate and the market rate as of the end date of these interim consolidated financial statements.

The fair value of the currency forward contracts is calculated by reference to the current forward exchange rates of contracts with similar maturity profiles.

The fair value of zero cost collar contracts is calculated by reference to the price differential between the agreed price range and the market price of the hedge’s object.

The counterparty risk uses the Z-Spread obtained from the curve of the bonds issued by counterparties, and they are deducted from each flow as appropriate.

Financial liabilities

The fair value of bonds issued was determined with reference to quoted market prices as they have standard terms and conditions.

The fair value of bank borrowings was determined based on discounted cash flow analysis applying the corresponding discount yield curves to the remaining term to maturity.

Disclosures of the fair value of financial liabilities at amortized cost are determined via the use of discounted cash flows, calculated over variables of the observable markets as of the date of informing the interim consolidated financial statements, and correspond to Level 2 of the fair value hierarchy.

The following table shows the compliance with the financial covenants (level of indebtedness, detailed in section 23.9.3), for the bonds issued prior to the year 2015, as required by domestic indentures (Chile):

Arauco applies the simplified approach regarding the expected losses from commercial debtors, which allows for the use of an estimate of expected credit losses over the instrument’s lifespan for all commercial accounts receivable. In order to establish this estimate, the commercial debtors have been grouped in relation to the corresponding risks for sales conditions as well as for tranches, including clients that are up-to-date or in default.

Explanation regarding the sales risk with letters of credit

The sales with letters of credit mainly occur in markets in Asia and the Middle East. Periodically, a credit assessment is conducted regarding the banks that issue the letters of credit with the purpose of obtaining their score over the basis of risk-qualification ratings, country-specific risk and financial statements. The decision of approving the issuing bank or asking for confirmation of the letter of credit is made in consideration to this assessment.

Explanation of the sales risk with credit line

Sales on credit are subject to the credit limit for each customer. The approval or rejection of a credit limit for all term sales is conducted by the Corporate Credit Sub-Division, as well as by the Credit and Collections area for North America, Brazil and Argentina, which report to the Corporate Finance Division. The regulations and procedures applicable for the correct control and risk management over the sales on credit are ruled by the Credit Policy.

A procedure that must be applied by all the companies of the Arauco group has been established for the approval and/or modification of client credit lines. Credit line requests are entered to the SAP that analyzes all available information. Afterwards, the same are either approved or rejected in each one of the internal committees of each company belonging to the Arauco group, depending on the maximum amount authorized by the Credit Policy. Lines of credit are renewed during this internal process on a yearly basis.

All sales are automatically controlled by a credit verification system, which has been configured to block any orders from clients who are delinquent in a given percentage of a debt and/or from clients whose line of credit, as of the time of the product’s shipping, has been exceeded or is overdue.

In order to minimize the credit risk for term or Open Account sales, it is Arauco’s policy to take out insurance to cover the export sales of companies Celulosa Arauco y Constitución S.A., Maderas Arauco S.A., Forestal Arauco S.A., Arauco Argentina S.A., and Arauco do Brasil S.A., as well as the domestic sales of Arauco Europe Coöperatief U.A., Arauco Argentina S.A., Araucomex S.A. de C.V., Arauco Industria de México, S.A. de C.V., Arauco Peru S.A., Arauco North America, Inc., Arauco Canada Ltd., Celulosa Arauco y Constitución S.A., Maderas Arauco S.A., Arauco Florestal Arapoti S.A., Arauco Forest Brasil S.A., Arauco do Brasil S.A. and Arauco Industria de Paineis S.A. Arauco works with credit insurance company Allianz Trade For Multinationals (Aa2 rating, as per risk rating companies Moody’s).

As another way of minimizing risk and supporting a line of credit approved by the Credit Committee through guarantees, Arauco holds guarantees such as mortgages, pledges, Standby letters of credit, bank performance bonds, checks, promissory notes, borrowings or any other that could be required under the laws of each country. The total amount held in guarantees amounts to ThU.S.$ 107,053, effective as of March 31, 2024, as summarized in the following chart. The procedure for guarantees is regulated by Arauco’s Policy on Guarantees, whose purpose is to control their accounting, due date and custody.

Guarantees Arauco group (ThU.S.$)
Guarantees debtors (received from clients)
Certificate of deposits	5,992	2.02	%
Standby	10,919	9.36	%
Promissory notes	74,972	74.68	%
Finance	2,941	1.67	%
Mortgage	-	0.94	%
Pledge	632	0.59	%
Loan agreement	11,597	10.74	%
Total guarantees	107,053	100.00	%

The maximum exposure to credit risk is limited to the value at amortized cost of the Debtors’ account for sales registered as of the date of this report, minus the percentage of sales insured by the aforementioned credit insurance companies and the guarantees granted in favor of Arauco.

In summary, the Open Account debt covered by the various insurance policies and guarantees amounts to 95.08% and, therefore, Arauco’s portfolio exposure amounts to 4.92%.

Secured open accounts receivable	ThU.S.$		%
Total open accounts receivable		543,283		100.00	%
Secured receivables (*)		516,554		95.08	%
Unsecured receivables		26,729		4.92	%

(*) Insured debt is deemed to be the portion of accounts receivable that is covered by a credit company or by guarantees such as standby letters of credit, mortgages, performance bonds, among others.

Investment policy:

Arauco has an Investment Policy which identifies and limits the financial instruments and the entities into which the Arauco companies, in particular Celulosa Arauco y Constitucion S.A., are authorized to invest. The Company’s Treasury Department is centralized with operations in Chile, USA, Canada and México. The Head Office is responsible for carrying out investments, cash flow surplus investments, and short and long-term debt subscriptions. Exceptions to this rule apply to short and long-term debt, and will be for specific investments made through other companies where authorization is required from the Chief Financial Officer.

For financial instruments, the only permitted investments are fixed income investments with adequate liquidity. Each instrument has defined classifications and limits, depending on duration and type of issuer.

Regarding intermediaries (such as banks, securities brokers and dealers of mutual funds that are bank affiliates), a scoring methodology is used to determine the relative degree of risk of each intermediary based on their financial position and assign score points that result in a credit risk rating to each intermediary. Arauco uses this scoring system to determine its investment limits for each intermediary.

The required information to evaluate the various criteria are obtained from published financial statements from the banks under evaluation and from the credit risk ratings of short and long-term debt securities obtained from rating agencies authorized by the Commission for the Financial Market (Fitch Ratings Chile, Humphreys and Feller Rate).

Any necessary exceptions regarding investment limits in each particular instrument or entity must have the authorization from Arauco’s Chief Financial Officer.

23.10.2 Type of risk: Liquidity risk

Description

This risk corresponds to Arauco’s ability to fulfill its financial obligations upon maturity.

Explanation of liquidity risk exposure and how this risk arises

Arauco’s exposure to liquidity risk is mainly from its obligations to bondholders, banks and financial institutions, creditors and other payables. Liquidity risk may arise if Arauco is unable to meet the net cash flow requirements, which sustain its operations under both normal and exceptional circumstances.

Explanation of objectives, policies and processes for risk management, and measurement methods

The Corporate Financial Management Division monitors on an ongoing basis the Company’s cash flow forecasts based on short and long-term forecasts and available financing alternatives. In order to manage the risk level of financial assets, Arauco follows its investment policy.

The following tables detail Arauco’s liquidity analysis for its financial liabilities as of March 31, 2024 and December 31, 2023.

The tables have been drawn up based on the contractual undiscounted cash outflows and their remaining contractual maturities.

23.10.3 Type of risk: Market risk – exchange rate

Description

Market risk arises from the probability of being affected by losses from fluctuations in currencies exchange rates in which assets and liabilities are denominated, in a functional currency other than the functional currency of Arauco.

Explanation of currency risk exposure and how this risk arises

Arauco is exposed to the foreign currency risk from currency fluctuations arising from sales, purchases and obligations undertaken in foreign currencies, such as the Chilean peso, Euro, Brazilian real or other foreign currencies. In the case of significant exchange rate variations, the Chilean peso is the currency that represents the main currency risk. See Note 11 for details assets and liabilities classified by currency.

Explanation of risk management objectives, policies and processes, and measurement methods

Arauco performs sensitivity analyses to measure the effect of this variable on equity and net result.

Sensitivity analysis considers a variation of +/- 10% of the exchange rate over the Chilean peso. This fluctuation range is considered possible given current market conditions as of the date of these interim consolidated financial statements. With all other variables at a constant rate, a U.S. dollar exchange rate variation of +/- 10% in relation to the Chilean peso would mean a change in the net income year after tax +/- 4.70% (equivalent to ThU.S.$ -/+ 4.715), and +/- 0.04% of equity (equivalent to ThU.S.$ -/+ 2,829).

Additionally, a sensitivity analysis is carried out assuming a variation of +/- 10% in the closing exchange rate on the Brazilian real, which is considered a possible range of fluctuation given the market conditions as of the date of these interim consolidated financial statements. With all the other variables constant, a variation of +/- 10% in the exchange rate of the dollar on the Brazilian real would mean a variation on the net income after tax +/- 14.58% (equivalent to ThU.S.$-/+$ 14.630) and a change on the equity of +/- 1.51% (equivalent to ThU.S.$ -/+$ 121,466).

23.10.4 Type of risk: Market risk – interest rate risk

Description

Interest rate risk refers to the sensitivity of the value of financial assets and liabilities in terms of interest rate fluctuations.

Explanation of interest rate risk exposure and how this risk arises

Arauco is exposed to risks due to interest rate fluctuations for bonds issued, bank borrowings and financial instruments that bear interest at a variable rate.

Explanation of risk management objectives, policies and processes, and measurement methods

Arauco completes its risk analysis by reviewing its exposure to changes in interest rates. As of March 31, 2024, 13.3% our financial debt accrues interest at variable rates. A change of +/- 10% in the interest rate is considered a possible range of fluctuation. Such market conditions would affect the income after tax at rate of +/- 1.54% (equivalent to ThU.S.$-/+ 1,544) and +/- 0.012% (equivalent to ThU.S.$-/+ 926) on equity.

23.10.5 Type of risk: Market risk – price of pulp risks

Description

Pulp prices are determined by world and regional market conditions. Prices fluctuate based on demand, production capacity, commercial strategies adopted by large-scale forestry companies, pulp and paper producers and by the availability of substitutes.

Explanation of price risk exposure and how this risk arises

Pulp prices are reflected in revenue from sales and directly affect the net income for the period.

As of March 31, 2024, revenue due to pulp sales accounted for 46.6% of total sales. Pulp prices are fixed on a monthly basis in accordance with the market. Forward contracts or other financial instruments are not used for pulp sales.

Explanation of risk management objectives, policies and processes, and measurement methods

This risk is approached in different ways. Arauco has a team of specialists who perform periodic market and competition analyses, providing tools to analyze and evaluate trends and adjust forecasts. Similarly, Arauco performs price financial sensitivity analysis in order to take the necessary safeguards to confront different scenarios in the best possible manner.

Sensitivity analysis considers a variation of +/- 10% in the average pulp price, a possible fluctuation range given current market conditions at the date of the closing balance. With all other variables constant, a variation of +/- 10% in the average pulp price would mean a variation of +/- 60.6% (equivalent to ThU.S.$-/+ 60,846) on the income for the year 2023 after tax and +/- 0.5% (equivalent to ThU.S.$ -/+ 36,508) on equity.

NOTE 26. DISTRIBUTABLE NET Profit AND EARNINGS PER SHARE

Distributable net profit

As a general policy, the Board of Directors of Arauco agreed that the net profit to be distributed as dividend is determined based on realized net gains/(losses) of any relevant variations in the value of unrealized assets and liabilities, which are excluded from the calculation of net profit during the period such changes are made.

As a result of the foregoing, for purposes of determining the distributable net profit of the Company, which is the same considered for calculating the minimum dividend required and additional dividend, the following unrealized gains/losses are excluded from the net profit for the year:

Unrealized gains/losses relating to the fair value recorded for forestry assets under IAS 41, adding them back to distributable net profit when they are realized through sale or disposed of by other means.

Those generated through the acquisition of entities. These results will be added back to net profit when they are realized through sale.

The deferred taxes associated with the amounts described in 1) and 2) above are also excluded.
