Basis of presentation for the consolidated financial statements
Basis of presentation for the consolidated financial statements	Note 2 2.1 These consolidated financial statements cover the following periods: (a) Consolidated Statements of Financial Position as of December 31, 2022 and 2021. (b) Consolidated Statements of Income from January 1 to December 31, 2022, 2021 and 2020. (c) Consolidated Statements of Comprehensive Income from January 1 to December 31, 2022, 2021 and 2020. (d) Consolidated Statements of Changes in Equity for the years ended December 31, 2022, 2021 and 2020. (e) Consolidated Statements of Cash Flows for the years ended December 31, 2022, 2021 and 2020. 2.2 Consolidated financial statements The consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with IFRS as issued by the IASB and they represent the full, explicit and unreserved adoption of IFRS. These consolidated financial statements fairly present the Company’s financial position, as of December 31, 2022 and 2021, the comprehensive results of operations, changes in equity and cash flows occurring for the three years ended December 31, 2022, 2021 and 2020. IFRS establish certain alternatives for their application, those applied by the Company are detailed in this Note and Note 3. The accounting policies used in the preparation of these consolidated financial statements comply with each IFRS in force at their date of presentation. The Company has revised its consolidated statement of financial position as of December 31, 2021 to correct the presentation of deferred tax assets and liabilities as follows(see Note 25.3). ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Original balances ​ ​ ​ Balances ​ reported as of Reclassification reclassified as of Items ​ December 31, 2021 ​ ​ ​ December 31, 2021 ​ ThUS$ ThUS$ ThUS$ Deferred tax assets — 135,904 135,904 Deferred tax liabilities 110,416 135,904 246,320 ​ This revision is not considered material to the previously issued financial statements. ​ 2.3 The consolidated financial statements have been prepared on the historical cost basis except for the following: (a) Inventories are recorded at the lower of cost and net realizable value. (b) Financial derivatives measured at fair value. (c) Certain financial investments measured at fair value with an offsetting entry in other comprehensive income. 2.4 Accounting pronouncements New accounting pronouncements (a) The following standards, interpretations and amendments are mandatory for the first time for annual periods beginning on January 1, 2022: ​ ​ ​ ​ ​ ​ ​ ​ Mandatory for annual periods Amendments and improvements Description ​ beginning on or after Reference the Conceptual Framework, amendments to IFRS 3 Minor changes were made to the IFRS 3 “Business Combinations” to update the references to the conceptual framework for financial reporting without changing the requirements for business combinations. 01-01-2022 Amendment to IAS 16, "Property, Plant and Equipment." Prohibits a company from deducting from the cost of property, plant and equipment amounts received from selling items produced while the company is preparing the asset for its intended use. Instead, a company will recognize such sales proceeds and related cost in profit or loss. 01-01-2022 Amendment to IAS 37, "Provisions, Contingent Liabilities and Contingent Assets". ​ Clarifies for onerous contracts what unavoidable costs a company must include to evaluate whether a contract generates losses. ​ 01-01-2022 Annual Improvements to IFRS Standards 2018-2020 The following improvements were finalized in May 2020: ​ ​ ​ ​ IFRS 9 Financial Instruments. ​ Clarifies what fees must be included in the "10 percent" test when evaluating whether to derecognize a financial liability ​ 01-01-2022 IFRS 16 Leases ​ The amendment to illustrative example 13 removes the illustration of the reimbursement of improvements to the leased asset made by the lessor to resolve any potential confusion in the treatment of lease incentives. ​ 01-01-2022 ​ ​ Management determined that the adoption of the aforementioned standards, amendments and interpretations did not significantly impact the company’s consolidated financial statements. (b) Standards, interpretations and amendments issued that had not become effective for financial statements beginning on January 1, 2022 and which the Company has not adopted early are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Mandatory for annual periods Standards and Interpretations Description beginning on or after Amendment to IAS 1 “Presentation of financial statements” on classification of liabilities. ​ These amendments clarify that the liabilities will be classified as current or non-current depending on the rights that exist at the close of the reporting period. The classification is not affected by the expectations of the entity or the events subsequent to the report date (for example, the receipt of a waiver or noncompliance with the pact). The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability. The amendment must be applied retroactively in accordance with IAS 8. Effective date of application January 1, 2022; however, such date was deferred to January 1, 2024. ​ 01-01-2024 Amendment to IAS 1 “Non-current liabilities with covenants”. ​ The amendment is aimed at improving the information that an entity provides when the payment terms of its liabilities can be deferred depending on compliance with covenants within the twelve months following the date of issue of the financial statements. ​ 01-01-2024 Amendments to IFRS 16 “Leases” ​ On sales with leaseback, which explains how an entity should recognize the rights to use the asset and how the profits or losses from the sale and leaseback should be recognized in the financial statements. ​ 01-01-2024 Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”. ​ The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies. ​ 01-01-2023 Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction. ​ These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition. ​ 01-01-2023 Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”, Published in September 2014. ​ These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business -whether it is housed in a subsidiary or not. A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. ​ undetermined ​ Management believes that the adoption of the above standards, amendments and interpretations will not have a significant impact on the Company’s financial statements. 2.5 (a) Subsidiaries The Company established control as the basis of consolidation of its financial statements. The Company controls a subsidiary when it is exposed, or has rights, to variable returns from its involvement with the subsidiary and has the ability to affect those returns through its power over the subsidiary. The consolidation of a subsidiary starts when the Group controls it and it is no longer included in the consolidation when this control is lost. Subsidiaries are consolidated through a line by line method, adding items that represent assets, liabilities, income and expenses with a similar content, and eliminating operations between companies within the SQM Group. Results for dependent companies acquired or disposed of during the period are included in the consolidated accounts from the date on which control is transferred to the SQM Group or until the date when this control ends, as relevant. To account for an acquisition of a business, the Company uses the acquisition method. Under this method, the acquisition cost is the fair value of assets delivered, equity securities issued, and incurred or assumed liabilities at the date of exchange. Assets, liabilities and contingencies identifiable assumed in a business combination are measured initially at fair value at the acquisition date. For each business combination, the Company will measure the non-controlling interest of the acquiree either at fair value or as proportional share of net identifiable assets of the acquire.

The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. (a) Joint operations The Company recognizes its direct right to the assets, liabilities, income and expenses of the joint arrangement. (b) Joint ventures and investments in associates Interests in companies over which joint control is exercised (joint ventures) or where an entity has significant influence (associates) are recognized using the equity accounting method. Significant influence is presumed when the investor owns over 20% of the investee’s share capital. The investment is recognized using this method in the statement of financial position at cost plus changes subsequent to acquisition and includes the proportional share of the associate’s equity. For these purposes, the percentage interest in the associate is used. The associated acquired goodwill is included in the investee’s book value and is not amortized. The debit or credit to the income statement reflects the proportional share of the profit or loss of the associate. Unrealized gains from transactions with joint ventures or associates are eliminated in accordance with the Company’s percentage interest in such entities. Any unrealized losses are also eliminated, unless that transaction provides evidence that the transferred asset is impaired. Changes in associate’s or joint ventures equity are recognized proportionally with a charge or credit to "Other Reserves" and are classified according to their origin. The reporting dates of the associate or joint ventures, the Company and related policies are similar for equivalent transactions and events in similar circumstances. In the event that significant influence is lost, or the investment is sold, or held for sale, the equity method is suspended, not recognizing the proportional share of the gain or loss. If the resulting value under the equity method is negative, the share of profit or loss is reflected as zero in the consolidated financial statements, unless there is a commitment by the Company to restore the capital position of the Company, in which case the related risk provision and expense are recorded. Dividends received by these companies are recorded by reducing the value of the investment and are shown in cash flows from operating activities, and the proportional share of the gain or loss recognized in accordance with the equity method is included in the consolidated income statement under "Share of Gains (Losses) of Associates and Joint Ventures Accounted for Using the Equity Method’’.

Significant accounting policies	Note 3 3.1 Classification of balances as current and non-current In the consolidated statement of financial position, balances are classified in consideration of their recovery (maturity) dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current. The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have. 3.2 Functional and presentation currency The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar. 3.3 Accounting policy for foreign currency translation (a) SQM group entities: The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows: - Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date. - Revenues and expenses of each profit or loss account are converted at monthly average exchange rates. - All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves. In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale. The main exchange rates and UF used to translate monetary assets and liabilities, expressed in foreign currency at the end and average of each period in respect to U.S. dollars, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Closing exchange rates ​ Average exchange rates ​ ​ As of ​ As of ​ As of ​ As of ​ ​ December 31, ​ December 31, ​ December 31, ​ December 31, Currencies 2022 2021 2022 2021 ​ ThUS$ ThUS$ ThUS$ ThUS$ Brazilian real 5.28 5.57 5.25 5.66 New Peruvian sol 3.81 3.99 3.83 4.04 Japanese yen 131.32 115.18 134.70 113.87 Euro 0.93 0.88 0.94 0.88 Mexican peso 19.50 20.54 19.60 20.90 Australian dollar 1.47 1.38 1.48 1.40 Pound Sterling 0.83 0.74 0.82 0.75 South African rand 17.01 15.94 17.28 15.88 Chilean peso 855.86 844.69 873.81 849.46 Chinese yuan 6.92 6.38 6.98 6.37 Indian rupee 82.73 74.42 82.52 75.40 Thai Baht 34.64 33.32 34.76 33.55 Turkish lira 18.71 13.28 18.66 13.54 Korean Won ​ 1,259.98 ​ 1,188.79 ​ 1,291.64 ​ 1,183.95 Indonesian Rupiah ​ 15,570.00 ​ 14,265.00 ​ 15,596.90 ​ 14,320.57 United Arab Emirates dirham ​ 3.67 ​ 3.67 ​ 3.67 ​ 3.67 Polish Zloty ​ 4.37 ​ 4.06 ​ 4.42 ​ 4.08 UF (*) 41.02 36.69 40.18 36.48 (*) US$ per UF (b) Transactions and balances The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income. Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined. 3.4 Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument. For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above. The statement of cash flows present cash transactions performed during the period, determined using the direct method. 3.5 Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows. The initial value of the Company's financial assets valued at fair value through comprehensive income includes the transaction costs that are directly attributable to acquiring that financial asset on the date the Company commits to acquiring it, whereas the transaction costs for financial assets valued at fair value through profit or loss are expensed. The initial value of trade and other receivables that do not include a significant financial component is their transaction price. After initial recognition, the Company measures its financial assets according to the Company’s business model for managing its financial assets and the contractual terms of its cash flows: (a) Financial debt instruments measured at amortized cost. Financial assets that meet the following conditions are included in this category (i) the business model that supports it aims to maintain the financial assets to obtain the contractual cash flows and the contractual conditions of the financial asset give place, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. The Company’s financial assets that meet these conditions are: (ii) cash equivalents; (iii) related party receivables; (iv) trade debtors; (v) other receivables. (b) Financial instruments at fair value. A financial asset should be measured at fair value through profit or loss or fair value through other comprehensive income, depending on the following: (i) "Fair Value Through Other Comprehensive Income": Assets held to collect contractual cash flows and to be sold, where the asset cash flows are only capital and interest payments, are measured at fair value through other comprehensive income. Changes in book values are through other comprehensive income, except for the recognition of impairment losses, interest income and exchange gains and losses, which are recognized in the income statement. When a financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to the income statement. Interest income from these financial assets is included in financial income using the effective interest method. (ii) "Fair Value Through Profit and Loss": Assets that do not meet the amortized cost or "Fair Value Through Other Comprehensive Income" criteria are valued at "Fair Value Through Profit and Loss". (c) Financial equity instruments at fair value through other comprehensive income. Equity instruments that are not classified as held for trading and which the Group has irrevocably chosen to recognize in this category. Amounts presented in other comprehensive income will not be subsequently transferred to profit or loss. 3.6 Financial assets impairment The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment method used depends on whether there has been a significant increase in credit risk. The Company applies simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue. The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for contract assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments. Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 21.7. The subsequent recovery of previously canceled amounts are credited to the same line. 3.7 Management accounts for its financial liabilities at amortized cost. Upon initial recognition, the Company measures its financial liabilities by their fair value less the transaction costs that are directly attributable to the acquisition of the financial liability. The Company subsequently measures its financial liabilities at amortized cost. ​ Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities. Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate. 3.8 The fair value of financial assets and liabilities is estimated using the following information. Although the data represent Management's best estimates, it is subjective and involves significant estimates regarding current economic conditions, market conditions and risk characteristics. Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary: Fair value estimation Financial assets and liabilities measured at fair value consist of forwards hedging the mismatch in the balance sheet and cash flows, options hedging the mismatch in the balance sheet and cross currency swaps to hedge bonds issued in local currency (Peso/UF). The fair value of the Company’s assets and liabilities recognized by cross currency swaps contracts is calculated as the difference between the present value of discounted cash flows of the asset (Peso/UF) and liability (Dollar) parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Financial options: the value recognized is calculated using the Black-Scholes method. In the case of CCS, the entry data used for the valuation models are UF, Peso, Dollar and basis swap rates. In the case of fair value calculations for interest rate swaps, the Forward Rate Agreement rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, for options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation. The effects on profit or loss of movements in these amounts is recognized in the caption finance costs, foreign currency translation gain (loss) or cash flow hedge reserve in the statement of comprehensive income, depending on each particular case. Estimate of fair value for disclosure purposes ● Cash equivalent approximates fair value due to the short-term maturities of these instruments. ● The fair value of current trade receivables is considered to be equal to the carrying amount due to the maturity of such accounts at short-term. ● Payables, current lease liabilities and other current financial liabilities are considered fair value equal to book value due to the short-term maturity of these accounts. ● The fair value of the debt (long-term secured and unsecured debentures; bonds denominated in local currency (Peso/UF) and foreign currency (Dollar), borrowings denominated in foreign currency (Dollar) and lease liabilities of the Company are calculated at current value of cash flows subtracted from market rates upon valuation, considering the terms of maturity and exchange rates. The UF and Peso rate curves are used as inputs for the valuation model. This information is obtained through from the renowned financial software company, Bloomberg, and the Chilean Association of Banks and Financial Institutions 3.9 When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified. 3.10 The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained. The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability. 3.11 The financial instruments derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows: a) Fair value hedge of assets and liabilities recognized (fair value hedges). ​ b) Hedging of a single risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge). At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations. The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items. The fair value of derivative instruments used for hedging purposes is shown in Note 12.3. Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss. a) Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate. b) The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized to income, as appropriate, depending on the nature of the hedged risk. The amounts accumulated in other comprehensive income are carried over to results when the hedged items are settled or when these have an impact on income. When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in other comprehensive income are immediately reclassified to profit or loss. 3.12 Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the profit of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure. The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of December 31, 2022, and 2021, the Company does not have any embedded derivatives. 3.13 Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets current. 3.14 Leases (a) Right-of-use assets The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment. (b) Lease liabilities On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment. When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset. Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement. (c) Short-term leases and low-value asset leases The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term. (d) Significant judgments in the determination of the lease term for contracts with renewal options. The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised. The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate. 3.15 The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others. For finished and in-process products, the company has four types of provisions, which are reviewed quarterly: (a) Provision associated with the lower value of stock: The provision is directly identified with the product that generates it and involves three types: (i) provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; (ii) provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; (iii) reprocessing costs of products that are unfeasible for sale due to current specifications. (b) Provision associated with physical differences in inventory : A provision is made for differences that exceed the tolerance considered in the respective inventory process (physical and annual inventories are taken for the productive units in Chile and the port of Tocopilla; the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately. (c) Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms. (d) Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management. Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision based on quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes. 3.16 Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent. 3.17 Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction. 3.18 Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced. In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable: (a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company. (b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the and its subsequent variation is recorded directly in results. Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets. Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date. Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred. The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements. Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value. Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred. The cost of interest is recognized by applying an average or average weighted interest rate for all financing costs incurred by the Company to the final monthly balances for works underway and complies with the requirements of IAS 23. Financing costs are not activated for periods that exceed the normal term for acquisition, construction or installation of the property; such is the case for delays, interruptions or temporary suspension of the project due to technical, financial or other problems that make it impossible to leave the property in usable conditions. 3.19 Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets and depreciated over their expected useful lives. Useful lives are reviewed on an annual basis. Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030. In the case of certain mobile equipment, depreciation is performed depending on the hours of operation. The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below: ​ ​ ​ ​ ​ ​ ​ ​ Minimum life or Maximum life or Life or average rate Classes of property, plant and equipment ​ rate (years) ​ rate (years) ​ in years Mining assets 3 10 8 Energy generating assets 5 16 10 Buildings 3 25 13 Supplies and accessories 4 10 8 Office equipment 5 10 9 Transport equipment 8 9 9 Network and communication equipment 4 12 8 IT equipment 5 10 8 Machinery, plant and equipment 3 25 10 Other fixed assets 3 15 9 ​ 3.20 Goodwill acquired represents the excess in acquisition cost on the fair value of the Company’s ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold. This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose. 3.21 Intangible assets other than goodwill mainly relate to water rights, costs for rights of way for electricity lines, software and licensing costs, the development of computer software and mining property and concession rights. (a) Water rights Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into: i) Finite rights with amortization using the straight-line method, and ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment. (b) Rights of way for electric lines As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible asset. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way. (c) Computer software Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives. Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received. The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives. (d) Mining property and concession rights The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are u

Financial risk management
Financial risk management	Note 4 4.1 The Company’s financial risk management policy is focused on safeguarding the stability and sustainability of the Company and its subsidiaries with regard to all such relevant financial uncertainty components. The Company’s operations are subject to certain financial risk factors that may affect its financial position or results. The most significant risk exposures are market risk, liquidity risk, currency risk, credit risk, and interest rate risk, among others. There could also be additional risks, which are either unknown or known but not currently deemed to be significant, which could also affect the Company’s business operations, its business, financial position, or profit or loss. The financial risk management structure includes identifying, determining, analyzing, quantifying, measuring and controlling these events. Management and in particular, Finance Management, is responsible for constantly assessing the financial risk. 4.2 (a) Credit risk A global economic contraction may have potentially negative effects on the financial assets of the Company, which are primarily made up of financial investments and trade receivables, and the impact on of our customers could extend the payment terms of the Company’s receivables by increasing its exposure to credit risk. Although measures are taken to minimize the risk, this global economic situation could mean losses with adverse material effects on the business, financial position or profit and loss of the Company’s operations. Trade receivables: to mitigate credit risk, the Company maintains active control of collection and requires the use of credit insurance. Credit insurance covers the risk of insolvency and unpaid invoices corresponding to 80% of all receivables with third parties. The credit risk associated with receivables is analyzed in Note 12.2 b) and the related accounting policy can be found in Note 3.6. Bank promissory notes: These are negotiable promissory notes issued at the request of customers by a bank payable upon maturity to guarantee collection. These notes are accepted based on the credit quality of the issuing banks. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, Financial institution ​ Financial assets ​ Rating ​ 2022 ​ ​ Moody´s S&P Fitch ThUS$ Agricultural Bank of China ​ Bank notes ​ P-1 ​ A-1 ​ F1+ ​ 10,334 Bank of China Limited Bank notes P-1 A-1 F1+ 27,936 Bank of Jiujiang Bank notes P-2 - - 1,964 Bank of Ningbo Bank notes P-2 - - 3,148 Others ​ Bank notes ​ - ​ - ​ - ​ 1,887 Total 45,269 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, Financial institution ​ Financial assets ​ Rating ​ 2021 ​ ​ Moody´s S&P Fitch ThUS$ Agricultural Bank of China ​ Bank notes ​ P-1 ​ A-1 ​ A ​ 860 Bank of China Limited Bank notes P-1 A-1 A 4,167 Bank of Communications Bank notes P-1 A-2 A 7,422 China CITIC Bank Corp Ltd Bank notes P-2 A-2 BBBu 2,623 China Construction Bank Corporation ​ Bank notes ​ - ​ A-1 ​ A ​ 7,122 China Everbrith Bank Co.

No significant modifications have been made during the period to risk models or parameters used in comparison to December 31, 2022, and no modifications have been made to contractual cash flows that have been significant during this period, except for considering in December 2022 the incorporation of cash flows received from insurance claims in the determination of the allowance for doubtful accounts. The effect of this change was not significant to the overall financial statements as of December 31, 2022. Financial investments: correspond to time deposits whose maturity date is greater than 90 days and less than 360 days from the date of investment, so they are not exposed to excessive market risks. The counterparty risk in implementation of financial operations is assessed on an ongoing basis for all financial institutions in which the Company holds financial investments. The credit quality of financial assets that are not past due or impaired can be evaluated by reference to external credit ratings (if they are available) or historical information on counterparty late payment rates: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, Financial institution ​ Financial assets ​ Rating ​ 2022 ​ ​ Moody´s S&P Fitch ThUS$ Banco crédito e Inversiones ​ Time deposits ​ - ​ A-2 ​ F2 ​ 150,578 Banco Itaú Corpbanca Time deposits P-2 A-2 - 284,915 Banco Santander – Santiago Time deposits P-1 A-2 - 124,689 Scotiabank Chile Time deposits - - F1+ 416,026 Sumitomo Mitsui Banking Time deposits P-1 - - 122,631 Banco de Chile Time deposits - A-1 - 602 JP Morgan US Dollar liquidity Fund Institucional ​ Investment fund ​ Aaa-mf ​ AAAm ​ AAAmmf ​ 435,485 Legg Mason - Western Asset Institutional cash reserves Investment fund - AAAm AAAmmf 590,661 Total 2,125,587 Banco crédito e Inversiones ​ Time deposits ​ - ​ A-2 ​ F2 ​ 187,707 Banco Itaú Corpbanca Time deposits P-2 A-2 - 15,048 Banco Santander - Santiago ​ Time deposits ​ P-1 ​ A-2 ​ - ​ 51,444 Banco Estado Time deposits P-1 A-1 - 85,055 Scotiabank Chile Time deposits - - F1+ 250,362 Banco de Chile Time deposits - A-1 - 150,259 Sumitomo Mitsui Banking ​ Time deposits ​ P-1 ​ - ​ - ​ 210,292 Total 950,167 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, Financial institution ​ Financial assets ​ Rating ​ 2021 ​ ​ Moody´s S&P Fitch ThUS$ Banco crédito e Inversiones ​ Time deposits ​ P-1 ​ A-2 ​ F2- ​ 9,752 Banco Itaú Corpbanca Time deposits P-2 A-2 - 8,001 Banco Santander – Santiago Time deposits P-1 A-2 - 9,052 Scotiabank Sud Americano Time deposits P-1 A-1 F1+ 10,750 Other banks Time deposits - - F1+ 200,100 JP Morgan US dollar Liquidity Fund Institutional Investment fund Aaa-mf AAAm AAAmmf 381,297 Legg Mason - Western Asset Institutional cash reserves Investment fund - AAAm AAAmmf 233,648 Total 852,600 Banco crédito e Inversiones ​ Time deposits ​ P-1 ​ A-2 ​ - ​ 34,325 Banco Itaú Corpbanca Time deposits P-2 A-2 - 195,471 Banco Santander - Santiago Time deposits P-1 A-2 - 65,899 Scotiabank Sud Americano Time deposits P-1 A-1 F1+ 289,421 Sumitomo Mitsui Banking Time deposits P-1 - F1 320,054 Total 905,170 ​ ​ (b) Currency risk The functional currency of the company is the US dollar, due to its influence on the determination of price levels, its relation to the cost of sales and considering that a significant part of the Company’s business is conducted in this currency. However, the global nature of the Company’s business generates an exposure to exchange rate variations of several currencies with the US dollar. Therefore, the Company maintains hedge contracts to mitigate the exposure generated by its main mismatches (net between assets and liabilities) in currencies other than the US dollar against the exchange rate variation, updating these contracts periodically depending on the amount of mismatching to be covered in these currencies. Occasionally, subject to the approval of the Board, the Company ensures short-term cash flows from certain specific line items in currencies other than the US dollar. A significant portion of the Company’s costs, especially salary payments, is associated with the Peso. Therefore, an increase or decrease in its exchange rate with the US dollar will provoke a respective decrease or increase to these accounting costs, which would be reflected in the Company’s profit and loss. By the fourth quarter of 2022, approximately US$644 million accumulated in expenses are associated with the Peso. As of December 31, 2022, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all the bond obligations denominated in UF, for a net liability fair value of US$11.73 million, this significant variation is explained primarily by the USD/CLP exchange rate observed at the end of the period. As of December 31, 2021, this value corresponds to a net liability amounting US$ 81.60 million. Furthermore, on of December 31, 2022, the Company held derivative instruments classified as hedges of foreign exchange risks associated with 100% of all nominative term deposits in UF and in pesos, at a net assets fair value of US$29.98 million. As of December 31, 2021, a net assets fair value was recognized for an amount of US$12.61 million. The Company contracted derivatives classified as foreign exchange hedges for all the expected disbursements in Australian dollars for the Mt Holland project (See note 8.5), to hedge its exposure to cash flow variations. The fair value of this hedge was a net asset of US$ 7.14 million as of December 31, 2022. ​ The Company had the following derivative contracts as of December 31, 2022 (at the absolute value of the sum of their notional values), to hedge the difference between its assets and liabilities: US$ 87.00 million CLP/US dollar derivative contracts, US$ 38.05 million Euro/US dollar derivative contracts, US$ 46.84 million in South African rand/US dollar derivative contracts, US$ 333.19 million in Chinese renminbi/US dollar derivative contracts, US$ 51.29 million in Australian dollar/US dollar derivative contracts and US$ 7.3 million in other currencies. These derivative contracts are held with domestic and foreign banks, which have the following credit ratings as of December 31, 2022. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial institution ​ Financial assets ​ Rating ​ ​ Moody´s S&P Fitch Banco Estado ​ Derivative ​ P-1 ​ A-1 ​ - Merrill Lynch International Derivative - A-1 - JP Morgan ​ Derivative ​ P-1 ​ A-2 ​ F1+ Morgan Stanley Derivative P-1 A-2 F1 The Bank of Nova Scotia Derivative P-1 A-1 F1+ Banco Itaú-Corpbanca Derivative P-2 A-2 - Goldman Sachs Derivative P-1 A-2 F1 ​ (c) Interest rate risk Interest rate fluctuations, primarily due to the uncertain future behavior of markets, may have a material impact on the financial results of the Company. Significant increases in the rate could make it difficult to access financing at attractive rates for the Company’s investment projects. The Company maintains current and non-current financial debt at fixed rates and LIBOR (maturing on May 30, 2023) rate plus spread and at a SOFR rate plus spread. As of December 31, 2022, the Company has 7.0% of its financial liabilities linked to variations SOFR and 2.5% of its financial liabilities subject to variations in the LIBOR rate. 100% of these obligations are covered by derivative instruments classified as interest rate hedges, whose value as of December 31, 2022 was a net asset of ThUS$ 1,666. Therefore, a significant increase in the rate would not affect the financial value of this hedged obligation. (d) Liquidity risk Liquidity risk relates to the funds needed to comply with payment obligations. The Company’s objective is to maintain financial flexibility through a comfortable balance between fund requirements and cash flows from regular business operations, bank borrowings, bonds, short term investments and marketable securities, among others. For this purpose, the Company keeps a high liquidity ratio 1 The Company has an important capital expense program which is subject to change over time. On the other hand, world financial markets go through periods of contraction and expansion that are unforeseeable in the long-term and may affect the Company’s access to financial resources. Such factors may have a material adverse impact on the Company’s business, financial position and results of operations. The Company constantly monitors the matching of its obligations with its investments, taking due care of maturities of both, from a conservative perspective, as part of this financial risk management strategy. As of December 31, 2022, the Company had unused, available revolving credit facilities with banks, for a total of US$694 million. Working capital bank lines committed and available at December 31, 2022 totaled US$100 million. 1 All current assets divided by all current liabilities. ​ Cash and cash equivalents are invested in highly liquid mutual funds with an AAA risk rating. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nature of undiscounted cash flows As of December 31, 2022 ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ (figures expressed in millions of US dollars) amount Less than 1 year 1 to 5 years Over 5 years Total Bank borrowings ​ 330.80 ​ 144.83 ​ 220.33 ​ — ​ 365.16 Unsecured obligations 2,550.60 405.17 616.66 2,935.15 3,956.98 Sub total 2,881.40 550.00 836.99 2,935.15 4,322.14 Hedging liabilities 62.53 40.76 20.43 12.68 73.87 Derivative financial instruments 5.82 5.82 — — 5.82 Sub total 68.35 46.58 20.43 12.68 79.69 Current and non-current lease liabilities 61.73 13.94 36.33 27.85 78.12 Trade accounts payable and other accounts payable 374.79 374.79 — — 374.79 Total 3,386.27 985.31 893.75 2,975.68 4,854.74 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nature of undiscounted cash flows As of December 31, 2021 ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ (figures expressed in millions of US dollars) amount Less than 1 year 1 to 5 years Over 5 years Total Bank borrowings ​ 70.08 ​ 1.05 ​ 70.64 ​ — ​ 71.69 Unsecured obligations 2,518.64 108.06 924.03 2,980.91 4,013.00 Sub total 2,588.72 109.11 994.67 2,980.91 4,084.69 Hedging liabilities 85.25 12.38 31.58 39.70 83.66 Derivative financial instruments 1.67 1.67 — — 1.67 Sub total 86.92 14.05 31.58 39.70 85.33 Current and non-current lease liabilities 54.22 8.88 30.97 29.08 68.93 Trade accounts payable and other accounts payable 279.65 279.65 — — 279.65 Total 3,009.51 411.69 1,057.22 3,049.69 4,518.60 ​ As of December 31, 2022, the nominal value of the agreed cash flows in US dollars of the CCS contracts were ThUS$ 512,236 (ThUS$ 549,239 as of December 31, 2021). 4.3 The Company documents and maintains methods for qualitatively measuring the effectiveness and efficiency of financial risk management strategies. These methods are consistent with SQM Group’s risk management profile.

(See Note 3.15). For raw materials, supplies, materials and parts, the lower value provision was associated to the proportion of defective materials and potential differences.

The objective is to hedge the exchange rate and inflation financial risks associated with bond obligations, exchange rate financial risks associated with investments in Chilean pesos, exchange rate financial risk associated with projects under construction in Australian dollars and interest rate financial risk associated with bank loans. Hedges are documented and qualitatively assessed to demonstrate their effectiveness based on a comparison of their critical terms. The hedges used by the Company as of the reporting date are highly effective given that the amounts, currencies, exchange dates and rates of the hedged item and the hedge are aligned, maintaining a close economic relationship. 12.4 Other current and non-current financial liabilities As of December 31, 2022 and 2021, the detail is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, 2022 ​ As of December 31, 2021 Other current and non-current financial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ liabilities Currents Non-Current Total Currents Non-Current Total ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ Liabilities at amortized cost Bank borrowings 130,840 197,522 328,362 85 69,613 69,698 Unsecured obligations 343,589 2,176,924 2,520,513 40,594 2,445,219 2,485,813 Derivative financial instruments For hedging 42,754 19,772 62,526 8,954 72,900 81,854 Non-Hedging 5,816 — 5,816 1,672 — 1,672 Total 522,999 2,394,218 2,917,217 51,305 2,587,732 2,639,037 ​ ​ ​ a) Bank borrowings, current: As of December 31, 2022, the detail of this caption is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debtor Payment of Creditor interest ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Currency or ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ adjustment ​ Payment of ​ ​ ​ ​ ​ ​ Tax ID No. Company Country Tax ID No. Financial institution Country index Payment of interest Repayment Effective rate Nominal rate 93.007.000-9 ​ SQM S.A. ​ Chile ​ O-E ​ Scotiabank Cayman ​ USA ​ US$ ​ Upon maturity ​ 05/30/2023 ​ 0.97 % 5.22 % 93.007.000-9 ​ SQM S.A. ​ Chile ​ 97.023.000-9 ​ Itaú ​ Chile ​ US$ ​ Upon maturity ​ 01/05/2023 ​ 4.50 % 4.50 % 93.007.000-9 ​ SQM S.A. ​ Chile ​ 97.030.000-7 ​ Banco Estado ​ Chile ​ US$ ​ Upon maturity ​ 01/05/2023 ​ 4.59 % 4.59 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debtor Creditor ​ Nominal amounts as of December 31, 2022 ​ Current amounts as of December 31, 2022 ​ ​ ​ ​ ​ ​ ​ ​ 90 days to 1 ​ Borrowing ​ Company ​ Financial institution ​ Up to 90 days ​ 90 days to 1 year Total ​ Up to 90 days ​ year ​ Subtotal ​ costs ​ Total ​ ​ ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ SQM S.A.

This is divided as follows: a) Short-term benefits for active employees are represented by salaries, social welfare benefits, paid time off, sickness and other types of leave, profit sharing and incentives and non-monetary benefits; e.g., healthcare service, housing, subsidized or free goods or services. These will be paid in a term which does not exceed twelve months. The Company maintains incentive programs for its employees, which are calculated based on the net result at the close of each period by applying a factor obtained from an evaluation based on their personal performance, the Company’s performance and other short-term and long-term indicators. b) Staff severance indemnities are agreed and payable based on the final salary, calculated in accordance with each year of service to the Company, with certain maximum limits in respect of either the number of years or in monetary terms. In general, this benefit is payable when the employee or worker ceases to provide his/her services to the Company and there are a number of different circumstances through which a person can be eligible for it, as indicated in the respective agreements; e.g. retirement, dismissal, voluntary retirement, incapacity or disability, death, etc. See Note 17.3. c) Obligations after employee retirement, described in Note 17.4. d) Retention bonuses for a group of Company executives, described in Note 17.6. 17.3 Other long-term benefits The actuarial assessment method has been used to calculate the Company’s obligations with respect to staff severance indemnities, which relate to defined benefit plans consisting of days of remuneration per year served at the time of retirement under conditions agreed in the respective agreements established between the Company and its employees. Under this benefit plan, the Company retains the obligation to pay staff severance indemnities related to retirement, without establishing a separate fund with specific assets, which is referred to as not funded Benefit payment conditions The staff severance indemnity benefit relates to remuneration days for years worked for the Company without a limit being imposed in regard of amount of salary or years of service. It applies when employees cease to work for the Company because they are made redundant or in the event of their death. This benefit is applicable up to a maximum age of 65 for men and 60 for women, which are the usual retirement ages according to the Chilean pensions system as established in Decree Law 3,500 of 1980. Methodology The determination of the defined benefit obligation is made under the requirements of IAS 19 “Employee benefits”. 17.4 Our subsidiary SQM NA, together with its employees established a pension plan until 2002 called the “SQM North America Retirement Income Plan”. This obligation is calculated measuring the expected future forecast staff severance indemnity obligation using a net salary gradual rate of restatements for inflation, mortality and turnover assumptions, discounting the resulting amounts at present value using the interest rate defined by the authorities. Since 2003, SQM NA offers benefits related to pension plans based on the 401-K system to its employees, which do not generate obligations for the Company. A settlement was reflected in the last quarter of 2022 for the purchase of annuities by the pension plan for all inactive participants. ​ ​ ​ ​ ​ ​ ​ ​ ​ As of As of As of ​ ​ December 31, ​ December 31, ​ December 31, Reconciliation Changes in the benefit obligation ​ 2022 ​ 2021 ​ 2020 ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ Opening balance 9,550 9,864 9,586 Current cost of service — — — Interest cost 255 240 280 Actuarial gains loss (1,357) (135) 506 Settlement ​ (7,739) ​ ​ ​ ​ Benefits paid (430) (419) (508) Total benefit obligation (A) 279 9,550 9,864 ​ ​ ​ ​ ​ ​ ​ ​ ​ As of As of As of Reconciliation ​ December 31, ​ December 31, ​ December 31, Changes in plan assets ​ 2022 ​ 2021 ​ 2020 ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ Fair value of plan assets at the start of the year 13,497 12,888 8,754 Real return (loss) in the plan assets (346) 1,028 4,642 Benefits paid (430) (419) (508) Settlement (7,739) — — Fair value of plan assets at the end of the year 4,982 13,497 12,888 Non-current-assets 4,703 3,947 3,025 Elements not yet recognized as components of the cost of periodic net pensions: Net actuarial loss at the beginning of the year 1,039 192 (3,634) Amortization during the year — — 326 Settlement ​ (1,627) ​ — ​ — Gain 647 847 3,500 Adjustment to recognize the minimum pension obligation 59 1,039 192 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the For the For the ​ ​ year ended ​ year ended ​ year ended Cost of service or benefits received during the year ​ 2022 ​ 2021 ​ 2020 ​ ThUS$ ​ ThUS$ ​ ThUS$ Financial cost 255 240 280 Real loss in plan assets (363) (316) (637) Settlement (1,627) — — Amortization of prior year losses ​ — ​ — ​ 326 Net periodic pension expenses (1,735) (76) (31) ​ ​ 17.5 As of December 31, 2022, and 2021, severance indemnities calculated at the actuarial value are as follows: ​ ​ ​ ​ ​ ​ ​ ​ As of As of As of ​ ​ December 31, ​ December 31, ​ December 31, Staff severance indemnities ​ 2022 ​ 2021 ​ 2020 ​ ThUS$ ThUS$ ThUS$ Opening balance (27,099) (32,199) (27,814) Current cost of service (4,204) (4,978) (3,804) Interest cost (1,928) (1,303) (1,486) Actuarial gain loss (5,305) 3,999 (2,826) Exchange rate difference 551 4,971 (1,513) Benefits paid during the year 3,086 2,411 5,244 Total (34,899) (27,099) (32,199) ​ (a) Actuarial assumptions The liability recorded for staff severance indemnity is valued at the actuarial value method, using the following actuarial assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of As of As of ​ ​ ​ December 31, ​ December 31, ​ December 31, ​ ​ Actuarial assumptions ​ 2022 ​ 2021 ​ 2020 ​ Annual/Years Mortality rate RV - 2014 RV - 2014 RV - 2014 Actual annual interest rate 5.12 % 5.67 % 3.65 % Voluntary retirement rate: Men 6.49 % 6.49 % 6.49 % Annual Women 6.49 % 6.49 % 6.49 % Annual Salary increase 3.00 % 3.00 % 3.00 % Annual Retirement age: Men 65 65 65 Years Women 60 60 60 Years ​ (b) Sensitivity analysis of assumptions As of December 31, 2022, 2021 and 2020, the Company has conducted a sensitivity analysis of the main assumptions of the actuarial calculation, determining the following: ​ ​ ​ ​ ​ ​ Effect + 100 basis Effect - 100 basis Sensitivity analysis as of December 31, 2022 ​ points ​ points ​ ThUS$ ThUS$ Discount rate (2,090) 2,352 Employee turnover rate (274) 307 ​ ​ ​ ​ ​ ​ ​ ​ Effect + 100 basis Effect - 100 basis Sensitivity analysis as of December 31, 2021 ​ points ​ points ​ ThUS$ ThUS$ Discount rate (1,614) 1,817 Employee turnover rate (212) 237 ​ ​ ​ ​ ​ ​ ​ ​ Effect + 100 basis Effect - 100 basis Sensitivity analysis as of December 31, 2020 ​ points ​ points ​ ThUS$ ThUS$ Discount rate (1,985) 2,234 Employee turnover rate (261) 291 ​ Sensitivity relates to an increase/decrease of 100 basis points. 17.6 The Company currently has a compensation plan with the purpose of motivating the Company’s executives and encouraging them to remain with the Company.

Our subsidiary SQM Salar holds exclusive rights to exploit the mineral resources in an area covering approximately 140,000 hectares of land in the Salar de Atacama in northern Chile, of which SQM Salar is only entitled to exploit the mineral resources in 81,920 hectares. These rights are owned by Corfo and leased to SQM Salar pursuant to the Lease Agreement. Corfo cannot unilaterally amend the Lease Agreement and the Project Agreement, and the rights to exploit the resources cannot be transferred. The Lease Agreement establishes that SQM Salar is responsible for making quarterly lease payments to Corfo according to specified percentages of the value of production of minerals extracted from the Salar de Atacama brines, maintaining Corfo’s rights over the Mining Exploitation Concessions and making annual payments to the Chilean government for such concession rights. The Lease Agreement was entered into in 1993 and expires on December 31, 2030. On January 17, 2018, SQM and Corfo reached an agreement to end an arbitration process directed by the arbitrator, Mr. Héctor Humeres Noguer, in case 1954-2014 of the Arbitration and Mediation Center of Santiago Chamber of Commerce and other cases related to it. The agreement signed in January 2018, includes important amendments to the lease agreement and project agreement signed between Corfo and SQM in 1993. The main modifications became effective on April 10, 2018 and requires an increase in the lease payments by increasing the lease rates associated with the sale of the different products produced in the Salar de Atacama, including lithium carbonate, lithium hydroxide and potassium chloride. This agreement has been amended since it was signed, and it is reasonable to expect that it will continue to be amended as mutually agreed by the parties. Additionally, SQM Salar commits to contribute to research and development efforts, as well as to the communities in close proximity to the Salar de Atacama and provide a percentage of total annual sales of SQM Salar to regional development. SQM Salar commits to contribute between US$10.8 million and US$18.9 million per year to research and development efforts, between US$10 to US$15 million per year to the communities in close proximity to the Salar de Atacama, and 1.7% of total annual sales of SQM Salar to regional development . 18.3 Changes in provisions ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Provision for ​ ​ ​ ​ ​ ​ dismantling, ​ ​ ​ ​ Description of items that gave rise to variations ​ ​ ​ restoration and ​ ​ ​ ​ as of December 31, 2022 ​ Legal complaints ​ rehabilitation cost ​ Other provisions ​ Total ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ Total provisions, initial balance 49,741 58,592 270,371 378,704 Changes Additional provisions 3,981 7,085 3,045,758 3,056,824 Provision used — — (2,060,321) (2,060,321) Increase(decrease) in foreign currency exchange (1) (35) 4 (32) Others (12) (11,647) (2,317) (13,976) Total Increase (decreases) 3,968 (4,597) 983,124 982,495 Total 53,709 53,995 1,253,495 1,361,199 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Provision for ​ ​ ​ ​ ​ ​ dismantling, ​ ​ ​ ​ Description of items that gave rise to variations ​ ​ ​ restoration and ​ ​ ​ ​ as of December 31, 2021 ​ Legal complaints ​ rehabilitation cost ​ Other provisions ​ Total ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ Total provisions, initial balance 10,165 61,265 95,353 166,783 Changes Additional provisions 48,012 7,302 232,254 287,568 Provision used (8,399) — (56,959) (65,358) Increase(decrease) in foreign currency exchange (37) — (35) (72) Others — (9,975) (242) (10,217) Total Increase (decreases) 39,576 (2,673) 175,018 211,921 Total 49,741 58,592 270,371 378,704 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Provision for ​ ​ ​ ​ ​ ​ dismantling, ​ ​ ​ ​ Description of items that gave rise to variations ​ ​ ​ restoration and ​ ​ ​ ​ as of December 31, 2020 ​ Legal complaints ​ rehabilitation cost ​ Other provisions ​ Total ​ ​ ThUS$ ​ ThUS$ ​ ThUS$ ​ ThUS$ Total provisions, initial balance 14,924 33,238 97,093 145,255 Changes Additional provisions 62,922 30,974 60,685 154,581 Provision used (67,685) — (59,939) (127,624) Increase(decrease) in foreign currency exchange 4 — (2,486) (2,482) Others — (2,947) — (2,947) Total Increase (decreases) (4,759) 28,027 (1,740) 21,528 Total 10,165 61,265 95,353 166,783 ​ ​ ​ 18.4 Other non-financial liabilities, Current ​ ​ ​ ​ ​ ​ As of As of ​ ​ December 31, ​ December 31, Description of other liabilities ​ 2022 ​ 2021 ​ ThUS$ ThUS$ Tax withholdings 46,518 21,546 VAT payable 43,439 26,111 Guarantees received 743 746 Accrual for dividend 7,370 34,184 Monthly tax provisional payments 289,326 23,319 Deferred income 19,341 5,605 Withholdings from employees and salaries payable 7,242 5,587 Accrued vacations (1) 29,642 23,467 Other current liabilities 2,856 1,109 Total 446,477 141,674 ​ (1) Vacation benefit (short-term benefits to employees, current) is in line with the provisions established in Chile’s Labor Code, which indicates that employees with more than a year of service will be entitled to annual vacation for a period of at least fifteen paid business days.

Disclosures on equity	Note 19 Disclosures on equity The detail and movements in the funds of equity accounts are shown in the consolidated statement of changes in equity. 19.1 The main object of capital management relative to the administration of the Company’s financial debt and equity is to ensure the regular conduct of operations and business continuity in the long term, with the constant intention of maintaining an adequate level of liquidity and in compliance with the financial safeguards established in the debt contracts in force. Within this framework, decisions are made in order to maximize the value of the company. Capital management must comply with, among others, the limits contemplated in the Financing Policy approved by the Shareholders’ Meeting, which establish a maximum consolidated indebtedness level of 1.5 times the debt to equity ratio. This limit can be exceeded only if the Company’s management has first obtained express approval at an Extraordinary Shareholders’ Meeting. The Company’s management controls capital management based on the following ratios: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of December 31, As of December 31, ​ ​ Capital Management ​ 2022 ​ 2021 ​ Description (1) ​ Calculation (1) Net Financial Debt (ThUS$) (721,980) 204,692 Financial Debt – Financial Resources Other current Financial Liabilities + Other Non-Current Financial Liabilities– Cash and Cash Equivalents – Other Current Financial Assets – Hedging Assets, non-current Liquidity 2.29 4.62 Current Assets divided by Current Liabilities Total Current Assets / Total Current Liabilities ROE 79.37 % 18.41 % Profit for the year divided by Total Equity Profit for the year / Equity Adjusted EBITDA (ThUS$) 5,838,439 1,185,453 Adjusted EBITDA EBITDA – Other income – Other gains (losses) - Share of Profit of associates and joint ventures accounted for using the equity method + Other expenses by function + Net impairment gains on reversal (losses) of financial assets – Finance income – Currency differences.

The SQM Group manages its capital structure and makes adjustments bases on the predominant economic conditions so as to mitigate the risks associated with adverse market conditions and take advantage of the opportunities there may be to improve the liquidity position of the SQM Group. There have been no changes in the capital management objectives or policy within the years reported in this document, no breaches of external requirements of capital imposed have been recorded. There are no contractual capital investment commitments. 19.2 Bond issuance contracts in the local market require the Company to maintain a Total Borrowing Ratio no higher than 1 for Series H, Series O and Series Q bonds, calculated over the last consecutive 12 months. Capital management must ensure that the Borrowing Ratio remains below 1.0, with respect to the Series H, Series O and Series Q bonds.

(ii) 80% of the profit for 2022 if all the following financial parameters are met: (a) “all current assets” divided by “all current liabilities” is equal to or greater than 2.0 times, and (b) the sum of “all current liabilities” and “all non-current liabilities”, less “cash equivalents”, less “other current financial assets”, all of the above divided by “total equity” in equal or less than 0.9 times.

(c) The amount of the provisional dividends may be higher or lower, provided that, based on the information available to the Board of Directors on the date when their distribution is agreed to, this will not have a negative or material effect on the Company's ability to carry out its investments, meet its obligations, and in general to comply with the investment and financing policy approved by the Ordinary Shareholders’ Meeting .

(e) Any remaining amount from the net profits from 2022 can be retained and used to finance the Company’s own operations or one or more of its investment projects, notwithstanding a possible distribution of dividends charged to accumulated profit that might be approved by the shareholders’ meeting or the possible future capitalization of all or part of it. (f) The payment of additional dividends is not being considered. It must be expressly stated that this dividends policy details the intention of the Company’s Board of Directors and its fulfillment depends on the actual profits obtained, as well as on the results indicated by the projections the Company makes from time to time or on the existence of particular conditions, as appropriate.

The amount in dispute is US$ 8.6 million, of which (i) US$ 1.3 million correspond to amounts assessed in excess, (ii) US$ 6.9 million correspond to the contested tax (minus effect on first category income tax), and (ii) US$ 0.4 million correspond to interest and fines. On November 28, 2022, the Santiago Court of Appeals ruled invalid the first instance ruling of the Tax and Customs Court, ordering the case reopened with the competent judge hearing evidence in the case. ​ (c) On July 15, 2021, SQM Salar filed a public right annulment suit and tax claim with the First Tax and Customs Court of the Metropolitan Region against tax assessments No. 65 and 66 for the 2017 and 2018 tax years. The amount in dispute is US$ 63.9 million, of which (i) US$ 17.6 million correspond to overcharged amounts, (ii) US$ 30.2 million correspond to the contested tax (minus effect on first category income tax), and (iii) US$ 16.1 million correspond to interest and fines. On November 7, 2022, the First Tax and Customs Court upheld SQM Salar's claim and ordered that these tax assessments be anulled. ​ On September 29, 2022, the SII assessed the differences for the 2019 tax year with respect to specific mining tax and other adjustments that totalled US$ 36.8 million, which includes an excess collection of US$ 9.7 million. SQM Salar paid the amount assessed, and has one year to appeal against this assessment, which it intends to do in a vigorous manner. The SII has not issued an assessment claiming differences in specific mining tax filed for tax years 2020 onward. If the SII uses criteria similar to that used in previous years, it may issue an assessment in the future for this period. The Company estimates a potential assessment of US$ 745.3 million (corporate income tax deducted) by the SII, without considering interests and fines. To date, the Company has recorded no effect corresponding to this tax on its profit and loss. 20.4 On September 6, 2018, representatives Claudia Nathalie Mix Jiménez, Gael Fernanda Yeomans Araya and Camila Ruslay Rojas Valderrama and the Poder Ciudadano political party filed an annulment suit against Corfo, which requested that the Salar de Atacama Project Agreement between Corfo and the Company, SQM Potasio and SQM Salar be annulled. The Companies have taken part of the process as interested third parties. In the event that the annulment claim is approved for the Salar de Atacama Project Agreement, SQM Salar may be prevented from the exploitation of the mining assets in the Salar de Atacama that it has leased from Corfo. 20.5 The subsidiary Isapre Norte Grande Ltda., in compliance with the provisions established by the Chilean Superintendence of Healthcare, which regulates the running of pension-related health institutions, maintains a guarantee in financial instruments delivered in deposits, custody and administration to Banco de Chile.

Based on IAS 12, paragraph 81, letter “c”, the company has estimated that the method that discloses the most significant information for users of the financial statements is the numeric conciliation between the tax benefit (expense) and the result of multiplying the accounting profit by the current rate in Chile. The aforementioned choice is based on the fact that the Company and subsidiaries established in Chile generate a large part of the Company’s tax benefit (expense). The amounts provided by subsidiaries established outside Chile have no relative importance in the overall context. Reconciliation between the tax benefit (expense) and the tax calculated by multiplying income before taxes by the Chilean corporate income tax rate. ​ ​ ​ ​ ​ ​ ​ ​ ​ (Expense) Benefit ​ ​ As of ​ As of ​ As of ​ ​ December 31, ​ December 31, ​ December 31, Income Tax Expense (Benefit) ​ 2022 ​ 2021 ​ 2020 ​ ThUS$ ThUS$ ThUS$ Consolidated income before taxes 5,486,496 841,221 238,538 ​ Statutory income tax rate in Chile 27 % 27 % 27 % Tax expense using the statutory tax rate (1,481,354) (227,130) (64,405) ​ Net effect of royalty tax payments (57,500) (13,350) (4,659) ​ Tax effect of income from regular activities exempt from taxation and dividends from abroad 3,490 (260) 1,786 ​ Tax rate effect of non-tax-deductible expenses for determining taxable profit (loss) (11,058) (2,226) (2,987) ​ Tax effect of tax rates supported abroad (25,053) (5,622) (2,077) ​ Effects of changes resulting from classifying a permanent item as a temporary one — — 4,826 ​ Other tax effects of reconciliation of accounting income to tax expense (737) (428) (2,663) ​ Tax expense using the effective tax rate (1,572,212) (249,016) (70,179) ​ ​ (j) The Group’s Companies are potentially subject to income tax audits by tax authorities in each country These audits are limited to a number of interim tax periods, which, in general, when they elapse, give rise to the expiration of these inspections. Tax audits, due to their nature, are often complex and may require several years. Below, we provide a summary of tax periods that are potentially subject to verification, in accordance with the tax regulations in force in the country of origin: (i) According to article 200 of Decree Law No 830, the taxes will be reviewed for any deficiencies in terms of payment and to generate any taxes that might arise. There is a 3-year prescriptive period for such review, dating from the expiration of the legal deadline when payment should have been made. This prescriptive period can be extended to 6 years for the revision of taxes subject to declaration, when such declaration has not been filed or has been presented with maliciously false information. (ii) In the United States, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return. In the event that an omission or error is detected in the tax return of sales or cost of sales, the review can be extended for a period of up to 6 years. (iii) In Mexico, the tax authority can review tax returns up to 5 years from the expiration date of the tax return. (iv) In Spain, the tax authority can review tax returns up to 4 years from the expiration date of the tax return. A subsidiary of the Company, SQM Iberian S.A., is being reviewed by the Spanish Tax Authority. This audit could involve adjustments to tax returns filed in Spain. (v) In Belgium, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return if no tax losses exist. In the event of detecting an omission or error in the tax return, the review can be extended for a period of up to 5 years. (vi) In South Africa, the tax authority may review tax returns for up to 3 years from the expiration date of the tax return. In the event that an omission or error in the tax return is detected, the review can be extended for a period of up to 5 years. A subsidiary of the Company, SQM Africa Pty., is being reviewed by the South African Tax Authority. This audit could involve adjustments to tax returns filed in South Africa. (vii) China: Tax returns up to 3 years old from the due date of the return can be reviewed, in special circumstances this can be extended to 5 years. When tax evasion or fraud is involved, the tax authorities will pursue the collection of tax and there is no time limit. (viii) Korea: Tax returns up to 5 years old from the due date of the return can be reviewed, but this can be extended to 7 years for cross-border transactions. Failure to file the tax return on the legal due date will result in this deadline being extended by up to 5 years and 10 years for cross-border transactions. When tax evasion or fraud is involved, it will be extended by up to 10 years and 15 years for cross-border transactions.

Significant accounting policies
Classification of balances as current and non-current	3.1 Classification of balances as current and non-current In the consolidated statement of financial position, balances are classified in consideration of their recovery (maturity) dates; i.e., those maturing within a period equal to or less than 12 months are classified as current counted from the closing date of the consolidated financial statements and those with maturity dates exceeding the aforementioned period are classified as non-current. The exception to the foregoing relates to deferred taxes, which are classified as non-current, regardless of the maturity they have.
Functional and presentation currency	3.2 Functional and presentation currency The Company’s consolidated financial statements are presented in United States dollars, without decimal places, which is the Company’s functional and presentation currency and is the currency of the main economic environment in which it operates. Consequently, the term foreign currency is defined as any currency other than the U.S. dollar.
Accounting policy for foreign currency translation	3.3 Accounting policy for foreign currency translation (a) SQM group entities: The revenue, expenses, assets and liabilities of all entities that have a functional currency other than the presentation currency are converted to the presentation currency as follows: - Assets and liabilities are converted at the closing exchange rate prevailing on the reporting date. - Revenues and expenses of each profit or loss account are converted at monthly average exchange rates. - All resulting foreign currency translation gains and losses are recognized as a separate component in translation reserves. In consolidation, foreign currency differences arising from the translation of a net investment in foreign entities are recorded in shareholder’s equity (“foreign currency translation reserve”). At the date of disposal, such foreign currency translation differences are recognized in the statement of income as part of the gain or loss from the sale. The main exchange rates and UF used to translate monetary assets and liabilities, expressed in foreign currency at the end and average of each period in respect to U.S. dollars, are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Closing exchange rates ​ Average exchange rates ​ ​ As of ​ As of ​ As of ​ As of ​ ​ December 31, ​ December 31, ​ December 31, ​ December 31, Currencies 2022 2021 2022 2021 ​ ThUS$ ThUS$ ThUS$ ThUS$ Brazilian real 5.28 5.57 5.25 5.66 New Peruvian sol 3.81 3.99 3.83 4.04 Japanese yen 131.32 115.18 134.70 113.87 Euro 0.93 0.88 0.94 0.88 Mexican peso 19.50 20.54 19.60 20.90 Australian dollar 1.47 1.38 1.48 1.40 Pound Sterling 0.83 0.74 0.82 0.75 South African rand 17.01 15.94 17.28 15.88 Chilean peso 855.86 844.69 873.81 849.46 Chinese yuan 6.92 6.38 6.98 6.37 Indian rupee 82.73 74.42 82.52 75.40 Thai Baht 34.64 33.32 34.76 33.55 Turkish lira 18.71 13.28 18.66 13.54 Korean Won ​ 1,259.98 ​ 1,188.79 ​ 1,291.64 ​ 1,183.95 Indonesian Rupiah ​ 15,570.00 ​ 14,265.00 ​ 15,596.90 ​ 14,320.57 United Arab Emirates dirham ​ 3.67 ​ 3.67 ​ 3.67 ​ 3.67 Polish Zloty ​ 4.37 ​ 4.06 ​ 4.42 ​ 4.08 UF (*) 41.02 36.69 40.18 36.48 (*) US$ per UF (b) Transactions and balances The Company’s non-monetary transactions in currencies other than the functional currency (Dollar) are translated to the respective functional currencies of Group entities at the exchange rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date. All differences are recorded in the statement of income except for all monetary items that provide an effective hedge for a net investment in a foreign operation. These items are recognized in other comprehensive income until disposal of the investment, when they are recognized in the statement of income. Charges and credits attributable to foreign currency translation differences on those hedge monetary items are also recognized in other comprehensive income. Non-monetary assets and liabilities that are measured at historical cost in a foreign currency are retranslated to the functional currency at the historical exchange rate of the transaction. Non-monetary items that are measured based on fair value in a foreign currency are translated using the exchange rate at the date on which the fair value is determined.
Consolidated statement of cash flows	3.4 Cash equivalents correspond to highly liquid short-term investments that are easily convertible into known amounts of cash and subject to insignificant risk of changes in their value and mature in less than three months from the date of acquisition of the instrument. For the purposes of the statement of cash flows, cash and cash equivalents comprise cash and cash equivalents as defined above. The statement of cash flows present cash transactions performed during the period, determined using the direct method.
Financial assets	3.5 Management determines the classification of its financial assets at fair value (either through other comprehensive income, or through profit or loss), and at amortized cost. The classification depends on the business model of the entity to manage the financial assets and the contractual terms of the cash flows. The initial value of the Company's financial assets valued at fair value through comprehensive income includes the transaction costs that are directly attributable to acquiring that financial asset on the date the Company commits to acquiring it, whereas the transaction costs for financial assets valued at fair value through profit or loss are expensed. The initial value of trade and other receivables that do not include a significant financial component is their transaction price. After initial recognition, the Company measures its financial assets according to the Company’s business model for managing its financial assets and the contractual terms of its cash flows: (a) Financial debt instruments measured at amortized cost. Financial assets that meet the following conditions are included in this category (i) the business model that supports it aims to maintain the financial assets to obtain the contractual cash flows and the contractual conditions of the financial asset give place, on specified dates, to cash flows that are only payments of the principal and interest on the outstanding principal amount. The Company’s financial assets that meet these conditions are: (ii) cash equivalents; (iii) related party receivables; (iv) trade debtors; (v) other receivables. (b) Financial instruments at fair value. A financial asset should be measured at fair value through profit or loss or fair value through other comprehensive income, depending on the following: (i) "Fair Value Through Other Comprehensive Income": Assets held to collect contractual cash flows and to be sold, where the asset cash flows are only capital and interest payments, are measured at fair value through other comprehensive income. Changes in book values are through other comprehensive income, except for the recognition of impairment losses, interest income and exchange gains and losses, which are recognized in the income statement. When a financial asset is derecognized, the cumulative gain or loss previously recognized in other comprehensive income is reclassified from equity to the income statement. Interest income from these financial assets is included in financial income using the effective interest method. (ii) "Fair Value Through Profit and Loss": Assets that do not meet the amortized cost or "Fair Value Through Other Comprehensive Income" criteria are valued at "Fair Value Through Profit and Loss". (c) Financial equity instruments at fair value through other comprehensive income. Equity instruments that are not classified as held for trading and which the Group has irrevocably chosen to recognize in this category. Amounts presented in other comprehensive income will not be subsequently transferred to profit or loss.
Financial assets impairment	3.6 Financial assets impairment The Company evaluates expected credit losses associated with its debt instruments carried at amortized cost and fair value through other comprehensive income. The impairment method used depends on whether there has been a significant increase in credit risk. The Company applies simplified approach to measure expected credit losses using the lifetime expected loss on all trade receivables. Expected credit losses are measured by grouping receivables by their shared credit risk characteristics and days overdue. The Company has concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for contract assets. Expected loss rates are based on sales payment profiles and historical credit losses within this period. Historical loss rates are adjusted to reflect current expectations and information regarding macroeconomic factors that affect the ability of customers to meet their commitments. Impairment losses from receivables and contract assets are shown as net impairment losses in the line “Impairment of financial assets and reversal of impairment losses,” see Note 21.7. The subsequent recovery of previously canceled amounts are credited to the same line.
Financial liabilities	3.7 Management accounts for its financial liabilities at amortized cost. Upon initial recognition, the Company measures its financial liabilities by their fair value less the transaction costs that are directly attributable to the acquisition of the financial liability. The Company subsequently measures its financial liabilities at amortized cost. ​ Financial liabilities measured at amortized cost are commercial accounts payable and other accounts payable and other financial liabilities. Amortized cost is based using the effective interest rate method. Amortized cost is calculated by considering any premium or discount on the acquisition and includes transaction costs that are an integral part of the effective interest rate.
Estimated fair value of financial instruments	3.8 The fair value of financial assets and liabilities is estimated using the following information. Although the data represent Management's best estimates, it is subjective and involves significant estimates regarding current economic conditions, market conditions and risk characteristics. Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary: Fair value estimation Financial assets and liabilities measured at fair value consist of forwards hedging the mismatch in the balance sheet and cash flows, options hedging the mismatch in the balance sheet and cross currency swaps to hedge bonds issued in local currency (Peso/UF). The fair value of the Company’s assets and liabilities recognized by cross currency swaps contracts is calculated as the difference between the present value of discounted cash flows of the asset (Peso/UF) and liability (Dollar) parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Financial options: the value recognized is calculated using the Black-Scholes method. In the case of CCS, the entry data used for the valuation models are UF, Peso, Dollar and basis swap rates. In the case of fair value calculations for interest rate swaps, the Forward Rate Agreement rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, for options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation. The effects on profit or loss of movements in these amounts is recognized in the caption finance costs, foreign currency translation gain (loss) or cash flow hedge reserve in the statement of comprehensive income, depending on each particular case. Estimate of fair value for disclosure purposes ● Cash equivalent approximates fair value due to the short-term maturities of these instruments. ● The fair value of current trade receivables is considered to be equal to the carrying amount due to the maturity of such accounts at short-term. ● Payables, current lease liabilities and other current financial liabilities are considered fair value equal to book value due to the short-term maturity of these accounts. ● The fair value of the debt (long-term secured and unsecured debentures; bonds denominated in local currency (Peso/UF) and foreign currency (Dollar), borrowings denominated in foreign currency (Dollar) and lease liabilities of the Company are calculated at current value of cash flows subtracted from market rates upon valuation, considering the terms of maturity and exchange rates. The UF and Peso rate curves are used as inputs for the valuation model. This information is obtained through from the renowned financial software company, Bloomberg, and the Chilean Association of Banks and Financial Institutions
Reclassification of financial instruments	3.9 When the Company changes its business model for managing financial assets, it will reclassify all its financial assets affected by the new business model. Financial liabilities cannot be reclassified.
Financial instruments derecognition	3.10 The Company derecognizes a financial asset when the contractual rights to the cash flows from the asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all the risks and rewards of ownership of the financial asset are transferred; and the control of the financial assets has not been retained. The Company derecognizes a financial liability when its contractual obligations or a part of these are discharged, paid to the creditor or legally extinguished from the principle responsibility contained in the liability.
Derivative and hedging financial instruments	3.11 The financial instruments derivatives are recognized initially at fair value as of the date on which the derivatives contract is signed and, they are subsequently assessed at fair value. The method for recognizing the resulting gain or loss depends on whether the derivative has been designated as an accounting hedge instrument and, if so, it depends on the type of hedging, which may be as follows: a) Fair value hedge of assets and liabilities recognized (fair value hedges). ​ b) Hedging of a single risk associated with a recognized asset or liability or a highly probable forecast transaction (cash flow hedge). At the beginning of the transaction, the Company documents the relationship that exists between hedging instruments and those items hedged, as well as their objectives for risk management purposes and the strategy to conduct different hedging operations. The Company also documents its evaluation both at the beginning and at the end of each period if the derivatives used in hedging transactions are highly effective to offset changes in the fair value or in cash flows of hedged items. The fair value of derivative instruments used for hedging purposes is shown in Note 12.3. Derivatives that are not designated or do not qualify as hedging derivatives are classified as current assets or liabilities, and changes in the fair value are directly recognized through profit or loss. a) Fair value hedge Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recorded in profit or loss, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk. The gain or loss relating to the effective portion of interest rate swaps that hedge fixed rate borrowings is recognized in profit or loss within finance costs, together with changes in the fair value of the hedged fixed rate borrowings attributable to interest rate risk. The gain or loss relating to the ineffective portion is recognized in profit or loss within other income or other expenses. If the hedge no longer meets the criteria for hedge accounting, the adjustment to the carrying amount of a hedged item for which the effective interest method is used is amortized to profit or loss over the period to maturity using a recalculated effective interest rate. b) The effective portion of the gain or loss on the hedging instrument is initially recognized with a debit or credit to other comprehensive income, while any ineffective portion is immediately recognized to income, as appropriate, depending on the nature of the hedged risk. The amounts accumulated in other comprehensive income are carried over to results when the hedged items are settled or when these have an impact on income. When a hedging instrument no longer meets the criteria for hedge accounting, any cumulative deferred gain or loss and deferred costs of hedging in equity at that time remains in equity until the forecast transaction occurs. When the forecast transaction is no longer expected to occur, the cumulative gain or loss and deferred costs of hedging that were reported in other comprehensive income are immediately reclassified to profit or loss.
Derivative financial instruments not considered as hedges	3.12 Derivative financial instruments not considered as hedges are recognized at fair value with the effect in the profit of the year. The Company has derivative financial instruments to hedge foreign currency risk exposure. The Company continually evaluates the existence of embedded derivatives in both its contracts and in its financial instruments. As of December 31, 2022, and 2021, the Company does not have any embedded derivatives.
Deferred acquisition cost from insurance contracts	3.13 Acquisition costs from insurance contracts are classified as prepayments and correspond to insurance contracts in force, recognized using the straight-line method and on an accrual basis independent of payment date. These are recognized under other non-financial assets current.
Leases	3.14 Leases (a) Right-of-use assets The Company recognizes right-of-use assets on the initial lease date (i.e., the date on which the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, adjusted by any new measurement of the lease liability. The cost of right-of-use assets includes the amount of recognized lease liabilities, direct initial costs incurred and lease payments made on the start date or sooner, less the lease incentives received. Unless the Company is reasonably sure it will take ownership of the leased asset at the end of the lease period, the assets recognized through right-of-use are depreciated in a straight line during the shortest period of their estimated useful life and lease period. Right-of-use assets are subject to impairment. (b) Lease liabilities On the lease start date, the Company recognizes lease liabilities measured at present value of lease payments that will be made during the lease period. Lease payments include fixed payments (including payments that are essentially fixed), less incentives for lease receivables, variable lease payments that are dependent on an index or rate and amounts that are expected to be paid as guaranteed residual value. Lease payments also include the exercise price of a purchase option if the Company is reasonably sure it will exercise this and penalty payments for terminating a lease, if the lease period reflects that the Company will exercise the option to terminate. Variable lease payments that are not dependent on an index or rate are recognized as expenses in the period that produces the event or condition that triggers payment. When calculating the present value of lease payments, the Company uses the incremental borrowing rate on the initial lease date if the interest rate implicit in the lease cannot be determined easily. After the start date, the lease liability balance will increase to reflect the accumulation of interest and will diminish as lease payments are made. Furthermore, the book value of lease liabilities is remeasured in the event of an amendment, a change in the lease period, a change in the fixed lease payments in substance or a change in the assessment to buy the underlying asset. Payments made that affect lease liabilities are presented as part of the financing activities in the cash flow statement. (c) Short-term leases and low-value asset leases The Company applies the short-term lease recognition exemption to leases with a lease term of 12 months or less starting on the start date and that don’t have a purchase option. It also applies the low-value asset lease recognition exemptions to leases less than the limit specified in the respective accounting standard. Lease payments in short-term leases and low-value asset leases are recognized as lineal expenses during the lease term. (d) Significant judgments in the determination of the lease term for contracts with renewal options. The Company determines the lease term as the non-cancellable period of the lease, together with periods covered by an option to extend the lease if it is reasonably certain that this will be exercised, or any period covered by an option to terminate the lease, if it is reasonably certain that this will not be exercised. The Company has the option, under some of its leases, to lease assets for additional terms. The Company applies its judgment when assessing whether it is reasonably certain that it will exercise the option to renovate. In other words, it considers all the relevant factors that create an economic incentive for it to exercise the option to renovate. After the start date, the Company reevaluates the lease term if there is a significant event or change in the circumstances that are under its control and affect its capacity to exercise (or not exercise) the option to renovate.
Inventory measurement	3.15 The method used to determine the cost of inventories is the weighted average monthly cost of warehouse storage. In determining production costs for own products, the company includes the costs of labor, raw materials, materials and supplies used in production, depreciation and maintenance of the goods that participate in the production process, the costs of product movement necessary to maintain stock on location and in the condition in which they are found, and also includes the indirect costs of each task such as laboratories, process and planning areas, and personnel expenses related to production, among others. For finished and in-process products, the company has four types of provisions, which are reviewed quarterly: (a) Provision associated with the lower value of stock: The provision is directly identified with the product that generates it and involves three types: (i) provision of lower realizable value, which corresponds to the difference between the inventory cost of intermediary or finished products, and the sale price minus the necessary costs to bring them to the same conditions and location as the product with which they are compared; (ii) provision for future uncertain use that corresponds to the value of those products in process that are likely not going to be used in sales based on the company’s long-term plans; (iii) reprocessing costs of products that are unfeasible for sale due to current specifications. (b) Provision associated with physical differences in inventory : A provision is made for differences that exceed the tolerance considered in the respective inventory process (physical and annual inventories are taken for the productive units in Chile and the port of Tocopilla; the business subsidiaries depend on the last zero ground obtained, but in general it is at least once a year), these differences are recognized immediately. (c) Potential errors in the determination of stock: The company has an algorithm that is reviewed at least once a year and corresponds to diverse percentages assigned to each inventory based on the product, location, complexity involved in the associated measurement, rotation and control mechanisms. (d) Provisions undertaken by business subsidiaries: these are historical percentages that are adjusted as zero ground is attained based on normal inventory management. Inventories of raw materials, materials and supplies for production are recorded at acquisition cost. Cyclical inventories are performed in warehouses, as well as general inventories every three years. Differences are recognized at the moment they are detected. The company has a provision based on quarterly calculations from percentages associated with each type of material (classification by warehouse and rotation), these percentages use the lower value resulting from deterioration or obsolescence as well as potential losses. This provision is reviewed at least annually, and considers the historical profit and loss obtained in the inventory processes.
Non-controlling interests	3.16 Non-controlling interests are recorded in the consolidated statement of financial position within equity but separate from equity attributable to the owners of the Parent.
Related party transactions	3.17 Transactions between the Company and its subsidiaries are part of the Company’s normal operations within its scope of business activities. Conditions for such transactions are those normally effective for those types of operations with regard to terms and market prices. The maturity conditions vary according to the originating transaction.
Property, plant and equipment	3.18 Property, plant and equipment are stated at acquisition cost, net of the related accumulated depreciation, amortization and impairment losses that they might have experienced. In addition to the price paid for the acquisition of tangible property, plant and equipment, the Company has considered the following concepts as part of the acquisition cost, as applicable: (a) Accrued interest expenses during the construction period that are directly attributable to the acquisition, construction or production of qualifying assets, which are those that require a substantial period prior to being ready for use. The interest rate used is that related to the project’s specific financing or, should this not exist, the average financing rate of the investor company. (b) The future costs that the Company will have to experience, related to the closure of its facilities at the end of their useful life, are included at the present value of disbursements expected to be required to settle the and its subsequent variation is recorded directly in results. Having initially recognized provisions for closure and refurbishment, the corresponding cost is capitalized as an asset in “Property, plant and equipment” and amortized in line with the amortization criteria for the associated assets. Construction-in-progress is transferred to property, plant and equipment in operation once the assets are available for use and the related depreciation and amortization begins on that date. Extension, modernization or improvement costs that represent an increase in productivity, ability or efficiency or an extension of the useful lives of property, plant and equipment are capitalized as a higher cost of the related assets. All the remaining maintenance, preservation and repair expenses are charged to expense as they are incurred. The replacement of assets, which increase the asset’s useful life or its economic capacity, are recorded as a higher value of property, plant and equipment with the related derecognition of replaced or renewed elements. Gains or losses which are generated from the sale or disposal of property, plant and equipment are recognized as income (or loss) in the period and calculated as the difference between the asset’s sales value and its net carrying value. Costs derived from the daily maintenance of property, plant and equipment are recognized when incurred. The cost of interest is recognized by applying an average or average weighted interest rate for all financing costs incurred by the Company to the final monthly balances for works underway and complies with the requirements of IAS 23. Financing costs are not activated for periods that exceed the normal term for acquisition, construction or installation of the property; such is the case for delays, interruptions or temporary suspension of the project due to technical, financial or other problems that make it impossible to leave the property in usable conditions.
Depreciation of property, plant and equipment	3.19 Property, plant and equipment are depreciated through the straight-line distribution of cost over the estimated technical useful life of the asset, which is the period in which the Company expects to use the asset. When components of one item of property, plant and equipment have different useful lives, they are recorded as separate assets and depreciated over their expected useful lives. Useful lives are reviewed on an annual basis. Fixed assets located in the Salar de Atacama consider useful life to be the lesser value between the technical useful life and the years remaining until 2030. In the case of certain mobile equipment, depreciation is performed depending on the hours of operation. The useful lives used for the depreciation and amortization of assets included in property, plant and equipment in years are presented below: ​ ​ ​ ​ ​ ​ ​ ​ Minimum life or Maximum life or Life or average rate Classes of property, plant and equipment ​ rate (years) ​ rate (years) ​ in years Mining assets 3 10 8 Energy generating assets 5 16 10 Buildings 3 25 13 Supplies and accessories 4 10 8 Office equipment 5 10 9 Transport equipment 8 9 9 Network and communication equipment 4 12 8 IT equipment 5 10 8 Machinery, plant and equipment 3 25 10 Other fixed assets 3 15 9 ​
Goodwill	3.20 Goodwill acquired represents the excess in acquisition cost on the fair value of the Company’s ownership of the net identifiable assets of the subsidiary on the acquisition date. Goodwill acquired related to the acquisition of subsidiaries is included in the line item goodwill, which is subject to impairment tests annually or more frequently if events or changes in circumstances indicate that it might be impaired and is stated at cost less accumulated impairment losses. Gains and losses related to the sale of an entity include the carrying value of goodwill related to the entity sold. This intangible asset is assigned to cash-generating units with the purpose of testing impairment losses. It is allocated based on cash-generating units expected to obtain benefits from the business combination from which the aforementioned goodwill acquired arose.
Intangible assets other than goodwill	3.21 Intangible assets other than goodwill mainly relate to water rights, costs for rights of way for electricity lines, software and licensing costs, the development of computer software and mining property and concession rights. (a) Water rights Water rights acquired by the Company relate to water from natural sources and are recorded at acquisition cost. The Company separates water rights into: i) Finite rights with amortization using the straight-line method, and ii) Indefinite rights, which are not amortized, given that these assets represent rights granted in perpetuity to the Company, which are subject to an annual impairment assessment. (b) Rights of way for electric lines As required for the operation of industrial plants, the Company has paid rights of way in order to install wires for the different electric lines on third party land. These rights are presented under intangible asset. Amounts paid are capitalized at the date of the agreement and amortized in the statement of income, according to the life of the right of way. (c) Computer software Licenses for IT programs acquired are capitalized based on their acquisition and customization costs. These costs are amortized over their estimated useful lives. Expenses related to the development or maintenance of IT programs are recognized as an expense as and when incurred. Costs directly related to the production of unique and identifiable IT programs controlled by the Group, and which will probably generate economic benefits that are higher than its costs during more than a year, are recognized as intangible assets. Direct costs include the expenses of employees who develop information technology software and general expenses in accordance with corporate charges received. The costs of development for IT programs are recognized as assets are amortized over their estimated useful lives. (d) Mining property and concession rights The Company holds mining property and concession rights from the Chilean and Western Australian Governments. Property rights from the State of Chile are usually obtained at no initial cost (other than the payment of mining patents and minor recording expenses) and once the rights on these concessions have been obtained, they are retained by the Company while annual patents are paid. Such patents, which are paid annually, are recorded as prepaid assets and amortized over the following twelve months. Amounts attributable to mining concessions acquired from third parties that are not from the Chilean Government are recorded at acquisition cost within intangible assets. Estimated useful lives or amortization rates used for finite identifiable intangible assets The finite useful life of mining properties is calculated using the productive unit method, except for the mining properties owned by Corfo, which have been leased to the Company and grant it the right to exclusively exploit them until December 31, 2030. The estimated useful life for software which they are amortized corresponds to the periods defined by the contracts or rights from which they originate. Minimum and maximum amortization lives or rates of intangible assets: ​ ​ ​ ​ ​ ​ Minimum Life or Maximum Life or Estimated useful life or amortization rate ​ Rate ​ Rate Water rights 5 years Indefinite Rights of way Indefinite Indefinite Corfo Mining properties (1) 8 years 8 years Mining rights Unit-production method Intellectual property 9 years 9 years IT programs 3 years 9 years (1) Mining properties owned by Corfo and leased to the Company, which grant it the exclusive right to exploit them until December 31, 2030.
Research and development expenses	3.22 Research and development expenses Research and development expenses are charged to profit or loss in the period in which the expenditure was incurred.
Exploration and evaluation expenses	3.23 Exploration and evaluation expenses The Company holds mining concessions for exploration and exploitation of ore, the Company gives the following treatment to expenses associated with exploration and assessment of these resources: Once the rights have been obtained, the Company records the disbursements directly associated with the exploration and evaluation of the deposit in execution as property, plant and equipment (construction in progress) at its cost. These disbursements include the following items: geological surveys, drilling, borehole extraction and sampling, activities related to the technical assessment and commercial viability of the extraction, and in general, any disbursement directly related to specific projects where the objective is to find ore resources. If the technical studies determine that the ore grade is not economically viable, the asset is directly charged to profit and loss. If determined otherwise, the asset described above is associated with the extractable ore tonnage which is amortized as it is used. (a) Limestone and metallic exploration These assets are included in Other Non-Current Non-Financial Assets, and the portion related to the area to be exploited in the year are reclassified to Current Inventory, if applicable. Costs related to metal exploration are charged to profit or loss in the period in which they are recognized if the project assessed doesn’t qualify for consideration as advanced exploration otherwise, these are amortized during the development stage. (b) Exploration and evaluation at the Mt. Holland Project Mount Holland exploration and evaluation expenditure is included in Property, plant and equipment, specifically in Construction in Progress.
Impairment of non-financial assets	3.24 Assets subject to depreciation and amortization are also subject to impairment testing, provided that an event or change in the circumstances indicates that the amounts in the accounting records may not be recoverable, an impairment loss is recognized for the excess of the book value of the asset over its recoverable amount. For assets other than goodwill, the Group annually assesses whether there is any indication that a previously recognized impairment loss may no longer exist or may have decreased. Should such indications exist, the recoverable amount is estimated. The recoverable amount of an asset is the higher between the fair value of an asset or cash generating unit less costs of sales and its value in use, and is determined for an individual asset unless the asset does not generate any cash inflows that are clearly independent from other assets or groups of assets. In evaluating value in use, estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessment, the value of money over time and the specific asset risks. Impairment losses from continuing operations are recognized with a debit to profit or loss in the categories of expenses associated with the impaired asset function. For assets other than goodwill, a previously recognized impairment loss is only reversed if there have been changes in the estimates used to determine the asset’s recoverable amount since the last time an impairment loss was recognized. If this is the case, the carrying value of the asset is increased to its recoverable amount. This increased amount cannot exceed the carrying value that would have been determined, net of depreciation, if an asset impairment loss had not been recognized in prior years. This reversal is recognized with a credit to profit or loss. Assets with indefinite lives are assessed for impairment annually.
Minimum dividend	3.25 As required by Chilean law and regulations, our dividend policy is decided upon from time to time by our Board of Directors and is announced at the Annual Ordinary Shareholders’ Meeting, which is generally held in April of each year. Shareholder approval of the dividend policy is not required. However, each year the Board must submit the declaration of the final dividend or dividends in respect of the preceding year, consistent with the then-established dividend policy, to the Annual Ordinary Shareholders’ Meeting for approval. As required by the Chilean Companies Act, unless otherwise decided by unanimous vote of the holders of issued shares, we must distribute a cash dividend in an amount equal to at least 30% of our consolidated net income for that year (determined in accordance with CMF regulations), unless and to the extent the Company has a deficit in retained earnings. (See Note 19.5).
Earnings per share	3.26 The basic earnings per share amounts are calculated by dividing the profit for the year attributable to the ordinary owners of the parent by the weighted average number of ordinary shares outstanding during the year. The Company has not conducted any type of operation of potential dilutive effect that would entail the disclosure of diluted earnings per share.
Other provisions	3.27 Provisions are recognized when: ● The Company has a present, legal or constructive obligation as the result of a past event. ● It is more likely than not that certain resources must be used, to settle the obligation. ● A reliable estimate can be made of the amount of the obligation. In the event that the provision or a portion of it is reimbursed, the reimbursement is recognized as a separate asset solely if there is certainty of income. In the consolidated statement of income, the expense for any provision is presented net of any reimbursement. Should the effect of the value of money over time be significant, provisions are discounted using a discount rate before tax that reflects the liability’s specific risks. When a discount rate is used, the increase in the provision over time is recognized as a finance cost. The Company’s policy is to maintain provisions to cover risks and expenses based on a better estimate to deal with possible or certain and quantifiable responsibilities from current litigation, compensations or obligations, pending expenses for which the amount has not yet been determined, collaterals and other similar guarantees for which the Company is responsible. These are recorded at the time the responsibility or the obligation that determines the compensation or payment is generated.
Obligations related to employee termination benefits and pension commitments	3.28 Obligations towards the Company’s employees comply with the provisions of the collective bargaining agreements in force, which are formalized through collective employment agreements and individual employment contracts, except for the United States, details in Note 17.4. These obligations are valued using actuarial calculations, according to the projected unit credit method which considers such assumptions as the mortality rate, employee turnover, interest rates, retirement dates, effects related to increases in employees’ salaries, as well as the effects on variations in services derived from variations in the inflation rate. Actuarial gains and losses that may be generated by variations in defined, pre-established obligations are directly recorded in “Other Comprehensive Income”. Actuarial losses and gains have their origin in deviations between the estimate and the actual behavior of actuarial assumptions or in the reformulation of established actuarial assumptions. The Company’s subsidiary SQM North America has established pension plans for its retired employees that are calculated by measuring the projected obligation using a net salary progressive rate net of adjustments for inflation, mortality and turnover assumptions, deducting the resulting amounts at present value. The net balance of this obligation is presented under the “Non-Current Provisions for Employee Benefits” (refer to Note 17.4).
Compensation plans	3.29 Compensation plans implemented through benefits provided in share-based payments settled in cash are recognized in the financial statements at their fair value, in accordance with IFRS 2. Changes in the fair value of options granted are recognized with a charge to payroll in the results for the period (see Note 17.6).
Revenue recognition	3.30 Revenue includes the fair value of considerations received or receivable for the sale of goods and services during the performance of the Company’s activities. Revenue is presented net of value added tax, estimated returns, rebates and discounts and after the elimination of sales among subsidiaries. Revenues are recognized when the specific conditions for each income stream are met, as follows: (a) Sale of goods The sale of goods is recognized when the Company has delivered products to the customer, and there is no obligation pending compliance that could affect the acceptance of products by the customer. The delivery does not occur until products have been shipped to the customer or confirmed as received by the customer, and the related risks of obsolescence and loss have been transferred to the customer and the customer has accepted the products in accordance with the conditions established in the sale, when the acceptance period has ended, or when there is objective evidence that those criteria required for acceptance have been met. Sales are recognized in consideration of the price set in the sales agreement, net of volume discounts and estimated returns at the date of the sale. Volume discounts are evaluated in consideration of annual foreseen purchases and in accordance with the criteria defined in agreements. (b) Sale of services Revenue associated with the rendering of services is recognized considering the degree of completion of the service as of the date of presentation of the consolidated classified statement of financial position, provided that the result from the transaction can be estimated reliably. (c) Income from dividends Income from dividends is recognized when the right to receive the payment is established.
Finance income and finance costs	3.31 Finance income is mainly composed of interest income from financial instruments such as term deposits and mutual fund deposits. Interest income is recognized in profit or loss at amortized cost, using the effective interest rate method. Finance costs are mainly composed of interest on bank borrowing expenses, interest on bonds issued and interest capitalized for borrowing costs for the acquisition, construction or production or qualifying assets. Borrowing costs and bonds issued are also recognized in profit or loss using the effective interest rate method.
Current income tax and deferred	3.32 Corporate income tax for the year is determined as the sum of current and deferred income taxes from the different consolidated companies. Current taxes are based on the application of the various types of taxes attributable to taxable income for the period. The Company periodically assesses the positions taken in the determination of taxes with respect to situations in which the applicable tax regulation is subject to interpretation and considers whether it is probable that a tax authority will accept an uncertain tax treatment. The Company measures its tax balances based on the most likely amount or expected value, depending on which method provides a better prediction of the resolution of uncertainty. Differences between the book value of assets and liabilities and their tax basis generate the balance of deferred tax assets or liabilities, which are calculated using the tax rates expected to be applicable when the assets and liabilities are realized. In conformity with current tax regulations, the provision for corporate income tax and taxes on mining activity is recognized on an accrual basis, presenting the net balances of accumulated monthly tax provisional payments for the fiscal period and associated credits. The balances of these accounts are presented in current income taxes recoverable or current taxes payable, as applicable. Income tax and variations in deferred tax assets or liabilities that are not the result of business combinations are recorded in income or equity, considering the origin of the gains or losses which have generated them. At each reporting period, the carrying amount of deferred tax assets is reviewed and recognized only if it is probable that future taxable amounts will be available to allow the recovery of all or a portion of the deferred tax assets. With respect to deductible temporary differences associated with investments in subsidiaries, associated companies and interest in joint ventures, deferred tax assets are recognized solely provided that it is more likely than not that the temporary differences will be reversed in the near future and that there will be taxable income with which they may be used. The deferred taxes related to items directly recognized in equity is registered with effect on other comprehensive income and not with effect on income. Deferred tax assets and liabilities are offset if there is a legally receivable right of offsetting tax assets against tax liabilities and the deferred tax is related to the same tax entity and authority. The recognized deferred tax assets refer to the amount of income tax to recover in future periods, related to: a) deductible temporary differences; b) compensation for losses obtained in prior periods, which have not yet been subject to tax deduction; and c) compensation for unused credits from prior periods. The Company recognizes deferred tax assets when it has the certainty that they can be offset with tax income from subsequent periods, unused tax losses or credits to date, but only when this availability of future tax income is probable and can be used for offsetting these unused tax losses or credits. The recognized deferred tax liabilities refer to the amount of income tax to pay in a future period, related to taxable temporary differences. The Company does not recognize deferred tax liabilities in all cases of taxable temporary differences associated with investments in subsidiaries, branches and associates, or with joint ventures, because based on the standard, the two following conditions both apply: (i) the parent company, investor or shareholder is capable of controlling the moment of the reversal of temporary differences; and (ii) it is probable that the temporary difference will not be reversed in the foreseeable future. Moreover, the Company does not recognize deferred tax assets for all the deductible temporary differences that originate from investments in subsidiaries, branches and associates, or from joint ventures, because it is unlikely that they meet the following requirements: (i) temporary differences are reversed in the foreseeable future; and (ii)
Operating segment reporting	3.33 Operating segment reporting IFRS 8 requires that companies adopt a management approach to disclose information on the operations generated by its operating segments. In general, this is the information that management uses internally for the evaluation of segment performance and making the decision on how to allocate resources for this purpose. An operating segment is a group of assets and operations responsible for providing products or services subject to risks and performance that are different from those of other business segments. A geographical segment is responsible for providing products or services in a given economic environment subject to risks and performance that are different from those of other segments operating in other economic environments. Allocation of assets and liabilities, to each segment is not possible given that these are associated with more than one segment, except for depreciation, amortization and impairment of assets, which are directly allocated in accordance with the criteria established in the costing process for product inventories to the corresponding segments.
Primary accounting criteria, estimates and assumptions	3.34 Management is responsible for the information contained in these consolidated annual accounts, which expressly indicate that all the principles and criteria included in IFRS, as issued by the IASB, have been applied in full. In preparing the consolidated financial statements of the Company and its subsidiaries, management has made significant judgments and estimates to quantify certain assets, liabilities, revenues, expenses and commitments included therein. Basically, these estimates refer to: ● Estimated useful lives are determined based on current facts and past experience and take into consideration the expected physical life of the asset, the potential for technological obsolescence, and regulations. (See Notes 3.21, 14 and 15). ● Impairment losses of certain assets - Goodwill and intangible assets that have an indefinite useful life are not amortized and are assessed for impairment on an annual basis, or more frequently if the events or changes in circumstances indicate that these may have deteriorated Other assets, including property, plant and equipment, exploration assets, goodwill and intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts exceed their recoverable amounts. If an impairment assessment is required, the assessment of fair value or value in use often requires estimates and assumptions such as discount rates, exchange rates, commodity prices, future capital requirements and future operating performance. Changes in such estimates could impact the recoverable values of these assets. Estimates are reviewed regularly by management (See Notes 14 and 15). ● Assumptions used in calculating the actuarial amount of pension-related and severance indemnity payment benefit commitments (See Note 17). ● Contingencies – The amount recognized as a provision, including legal, contractual, constructive and other exposures or obligations, is the best estimate of the consideration required to settle the related liability, including any related interest charges, considering the risks and uncertainties surrounding the obligation. In addition, contingencies will only be resolved when one or more future events occur or fail to occur. Therefore, the assessment of contingencies inherently involves the exercise of significant judgment and estimates of the outcome of future events. The Company assesses its liabilities and contingencies based upon the best information available, relevant tax laws and other appropriate requirements (See Note 20). If the Company is unable to rationally estimate the obligation or concluded no loss is probable but it is reasonably possible that a loss may be incurred, no provision is recorded but disclosed in the notes to the consolidated financial statements. ● Volume determination for certain in-process and finished products is based on topographical measurements and technical studies that cover the different variables (density for bulk inventories and density and porosity for the remaining stock, among others), and related allowance. ● Estimates for obsolescence provisions to ensure that the carrying value of inventory is not in excess of the net realizable inventory valuation. (See Note 10). Even though these estimates have been made on the basis of the best information available on the date of preparation of these consolidated financial statements, certain events may occur in the future and oblige their amendment (upwards or downwards) over the next few years, which would be made prospectively.

The amendment also clarifies what IAS 1 means when referring to “liquidation” of a liability. The amendment must be applied retroactively in accordance with IAS 8. Effective date of application January 1, 2022; however, such date was deferred to January 1, 2024. ​ 01-01-2024 Amendment to IAS 1 “Non-current liabilities with covenants”. ​ The amendment is aimed at improving the information that an entity provides when the payment terms of its liabilities can be deferred depending on compliance with covenants within the twelve months following the date of issue of the financial statements. ​ 01-01-2024 Amendments to IFRS 16 “Leases” ​ On sales with leaseback, which explains how an entity should recognize the rights to use the asset and how the profits or losses from the sale and leaseback should be recognized in the financial statements. ​ 01-01-2024 Amendments to IAS 1: “Presentation of the Financial Statements” and IAS 8 “Accounting policies, changes in accounting estimates and errors”. ​ The amendments are intended to improve disclosures of accounting policies and to help users of financial statements distinguish between changes in accounting estimates and changes in accounting policies. ​ 01-01-2023 Amendment to IAS 12 - Deferred taxes related to assets and liabilities that arise from a single transaction. ​ These amendments require companies to recognize deferred taxes on transactions that result in equal amounts in taxable and deductible temporary differences in the initial recognition. ​ 01-01-2023 Amendment to IFRS 10 “Consolidated Financial Statements” and IAS 28 “Investments in Associates and Joint Ventures”, Published in September 2014. ​ These amendments address an inconsistency between the requirements in IFRS 10 and those in IAS 28 in dealing with the sale or contribution of assets between an investor and its associate or joint venture. The main consequence of the amendments is that a full gain or loss is recognized when a transaction involves a business -whether it is housed in a subsidiary or not. A partial gain or loss is recognized when a transaction involves assets that do not constitute a business, even if these assets are housed in a subsidiary. ​ undetermined ​
