The matter was then remanded to the District Court for a complete retrial. On May 17, 2018, after a new trial in the District Court, a jury ruled in favor of SQMNA. On September 8, 2021, a jury found in favor of Pomona and against SQMNA on a single cause of action for strict products liability under California law.

On February 1, 2024, the Court of Appeals of Santiago, pending the ruling, revoked the first instance ruling and issued another in its replacement by virtue of which it partially accepted the claim, ordering the Company to pay the total sum of ThUS$52. SQM has filed an appeal, which resolution is pending. (g)In January 2018, the company Transportes Buen Destino S.A. filed an arbitration claim under CAM rules against SQM Salar for controversies resulting from the execution of transport contracts for lithium brine and transport of salts.

The Company and its subsidiaries have been involved and will probably continue to be involved either as plaintiffs or defendants in certain judicial proceedings that have been and will be heard by the arbitration or ordinary courts of justice that will make the final decision. Those proceedings that are regulated by the appropriate legal regulations are intended to exercise or oppose certain actions or exceptions related to certain mining claims either granted or to be granted and that do not or will not affect in an essential manner the development of the Company and its subsidiaries. Soquimich Comercial S.A., a subsidiary, has been involved and will probably continue being involved either as plaintiff or defendant in certain judicial proceedings through which it intends to collect and receive the amounts owed, the total nominal value of which is approximately US$1.05 million. The Company and its subsidiaries have made efforts and continues making efforts to obtain payment of certain amounts that are still owed to the Company due to its activities. Such amounts will continue to be required using judicial or non-judicial means by the plaintiffs, and the actions and exercise related to these are currently in full force and effect. 20.2 Environmental contingencies Through a ruling dated November 28, 2016, which was amended by a ruling dated December 23, 2016, the SMA filed charges against SQM Salar for extracting brine in excess of authorized amounts, progressively impacting the vitality of algarrobo trees, delivering incomplete information, modifying variables in the follow-up plan, and other matters. SQM Salar submitted a compliance program that was accepted by the SMA, although rendered null and void by the Environmental Court of Antofagasta in December 2019. In October 2020, the SMA made further observations to the compliance program, which were addressed through the submission of a reformulated compliance program, incorporating improvements in line with the Antofagasta Environmental Court ruling. On August 29, 2022, the SMA approved the compliance program submitted by SQM Salar, which was subjected to a claim filed by the Council of Atacameño Peoples with the Antofagasta Environmental Court. If the Council of Atacameño Peoples’ claim against SMA’s resolution that approved the compliance program is accepted and the program is annulled, the sanction process against SQM Salar could be resumed. This process may conclude with the application of fines up to US$ 9 million, temporary or permanent closure of facilities and in extreme circumstances, revocation of the respective environmental permit. 20.3 Tax Contingencies The Chilean IRS has sought to extend the specific mining tax to lithium mining, which cannot be concessioned under the legal system. As of December 31, 2023, the Chilean IRS has charged SQM a total of US$ 986.3 million, which SQM has paid, for the specific mining tax applied to lithium, corresponding to tax years 2012 to 2023 (business years 2011 to 2022). SQM Salar has filed seven tax claims against the Chilean IRS. The total amount associated with the tax claims is US$ 201.3 million, and it has a pending claim for US$ 785.0 million. Both amounts, already paid by SQM Salar, totaled US$986.3 million as of December 31, 2023, including an overcharge amount of US$59.5 million, a tax amount of US$818.0 million and an interest and fees amount of US$108.7 million. On April 5, 2024, the Santiago Court of Appeal issued a ruling in one of the Claims, the tax role case No. 312-2022, and revoked the ruling that had previously been handed down by the Tax and Customs Court of the Metropolitan Region, which upheld the public law annulment action filed by SQM Salar, corresponding to settlements for the 2017 and 2018 tax years. Although the ruling of the Santiago Court of Appeal does not affect all other Claims, filed by the SQM Salar against the Chilean IRS, and is still subject to appeal by SQM Salar, it prompted the review of the accounting treatment for the tax claims by the Company's Board of Directors. Consequently, the Company recognized a tax expense adjustment amounting US$1,089.5 million for the year ended December 31, 2023 (US$926.7 million relating to tax years 2011 to 2022 and US$162.7 million associated to tax year 2023), which corresponds to the impact that the interpretation of the Santiago Court of Appeal ruling could have on the Claims. As of December 31, 2023 and 2022, the Company presents non current tax receivables amounting US$ 59.5 million and US$ 127.1 million, respectively. The claims are as follows. (a) On August 26, 2016, a tax claim was filed before the Third Tax and Customs Court of the Metropolitan Region against assessments 169, 170, 171 and 172, issued by the Chilean IRS for the tax years 2012 to 2014.

The case is currently in the evidentiary stage. (b) On March 24, 2017, a tax claim was filed before the Third Tax and Customs Court of the Metropolitan Region against assessment 156 issued by the Chilean IRS for the tax year 2015.

(c) On March 24, 2017, a tax claim was filed before the Third Tax and Customs Court of the Metropolitan Region against assessment 207 issued by the Chilean IRS for the tax year 2016. The amount in dispute is US$ 5.5 million, where (i) US$ 1.2 million is overpaid taxes, (ii) US$ 3.8 million is the tax claim, net of corporate income taxes and (iii) US$0.5 million is associated interest and penalties. The case is currently in the evidentiary stage. (d) On July 15, 2021, SQM Salar filed before the First Tax and Customs Court of the Metropolitan Region a tax annulment and claim against assessments 65 and 66, issued by the Chilean IRS, for the tax years 2017 and 2018. The amount in dispute is US$ 63.9 million, where (i) US$ 17.6 million is overpaid taxes, (ii) US$ 30.2 million is the tax claim, net of corporate income tax, and (iii) US$ 16.1 million is associated interest and penalties. On November 7, 2022, the First Tax and Customs Court upheld SQM Salar's claim and ordered the annulment of these tax assessments. This judgment was appealed by the Chilean IRS and on April 5, 2024, the Court of Appeals of Santiago revoked the first instance ruling in that it accepted the public law annulment action aimed at challenging the charges, accepting the claim only with respect to those miscalculated items recognized by the Chilean IRS. (e) On June 30, 2023, SQM Salar filed before the First Tax and Customs Court of the Metropolitan Region a tax annulment and claim against assessment 23, issued by the Chilean IRS, for the tax year 2019. The amount in dispute is US$ 36.7 million, where (i) US$ 9.7 million is overpaid taxes, and (ii) US$ 27.0 million is the tax claim, net of corporate income taxes. The trial is currently at the discussion stage. (f) On January 19, 2024, SQM Salar filed before the Third Tax and Customs Court of the Metropolitan Region, a tax annulment and claim against assessment 56 issued by the Chilean IRS for the tax years 2020 and 2021. The amount in dispute is US$ 20.7 million, where US$ 5.6 million is overpaid taxes and US$ 15.1 million is the tax claim, net of corporate income taxes. The case is currently at the discussion stage. (g) On January 19, 2024, SQM Salar filed before the Third Tax and Customs Court of the Metropolitan Region a tax annulment and claim against assessment 1, issued by the Chilean IRS, for the tax year 2022. The amount in dispute is US$ 53.5 million, where (i) US$ 14.4 million is overpaid taxes, (ii) US$ 36.1 million is the tax claim, net of corporate income taxes and (iii) US$ 3 million is associated interest and penalties. The case is currently at the discussion stage. The assessments and pending claims are as follows: On December 19, 2023, the Chilean IRS invoiced the Company for a sum of US$785 million for the tax year 2023 (covering the 2022 business year), pertaining to the specific tax on mining activities. Within this total, US$691.2 million represents the tax claimed, net of corporate income tax, and US$10.9 million is the excess tax payments. The Chilean IRS has not invoiced the Company for specific mining tax with respect to the 2024 tax year (2023 business year). If the Chilean IRS uses criteria similar to that used in previous years, then it may invoice the Company in the future for the 2023 business year, which the Company estimates could be an amount of approximately US$ 162.7 million, net of corporate income taxes, but excluding interest and penalties. See Note 26.2 “Disclosures on events occurring after the reporting date” for a description of subsequent events. 20.4 Indirect guarantees As of December 31, 2023 and 2022, there are no indirect guarantees. 20.5 Other matters The Company is required to be in compliance with all applicable laws and regulations in Chile and internationally with respect to anti-corruption, anti-money laundering and other regulatory matters, including the Foreign Corrupt Practices Act (FCPA). The Company has received a request for information and subpoena from the SEC requesting information related to our business operations, compliance program, and allegations of potential violations of the FCPA and other anti-corruption laws. The SEC has said that the investigation is a non-public, fact-finding inquiry and we are not aware that any conclusion has been reached by the SEC. Management has initiated an internal review to identify materials that are responsive to the SEC’s inquiry and are actively cooperating in the SEC’s review by providing the information requested.

This judgment was appealed by the Chilean IRS and on April 5, 2024, the Court of Appeals of Santiago revoked the first instance ruling in that it accepted the public law annulment action aimed at challenging the charges, accepting the claim only with respect to those miscalculated items recognized by the Chilean IRS.

(e) On June 30, 2023, SQM Salar filed before the First Tax and Customs Court of the Metropolitan Region a tax annulment and claim against assessment 23, issued by the Chilean IRS, for the tax year 2019. The amount in dispute is US$ 36.7 million, where (i) US$ 9.7 million is overpaid taxes, and (ii) US$ 27.0 million is the tax claim, net of corporate income taxes. The trial is currently at the discussion stage.

(f) On January 19, 2024, SQM Salar filed before the Third Tax and Customs Court of the Metropolitan Region, a tax annulment and claim against assessment 56 issued by the Chilean IRS for the tax years 2020 and 2021. The amount in dispute is US$ 20.7 million, where US$ 5.6 million is overpaid taxes and US$ 15.1 million is the tax claim, net of corporate income taxes. The case is currently at the discussion stage.

(g) On January 19, 2024, SQM Salar filed before the Third Tax and Customs Court of the Metropolitan Region a tax annulment and claim against assessment 1, issued by the Chilean IRS, for the tax year 2022. The amount in dispute is US$ 53.5 million, where (i) US$ 14.4 million is overpaid taxes, (ii) US$ 36.1 million is the tax claim, net of corporate income taxes and (iii) US$ 3 million is associated interest and penalties. The case is currently at the discussion stage.

On December 19, 2023, the Chilean IRS invoiced the Company for a sum of US$785 million for the tax year 2023 (covering the 2022 business year), pertaining to the specific tax on mining activities. Within this total, US$691.2 million represents the tax claimed, net of corporate income tax, and US$10.9 million is the excess tax payments.

The Chilean IRS has not invoiced the Company for specific mining tax with respect to the 2024 tax year (2023 business year). If the Chilean IRS uses criteria similar to that used in previous years, then it may invoice the Company in the future for the 2023 business year, which the Company estimates could be an amount of approximately US$ 162.7 million, net of corporate income taxes, but excluding interest and penalties.

The Company is required to be in compliance with all applicable laws and regulations in Chile and internationally with respect to anti-corruption, anti-money laundering and other regulatory matters, including the Foreign Corrupt Practices Act (FCPA). The Company has received a request for information and subpoena from the SEC requesting information related to our business operations, compliance program, and allegations of potential violations of the FCPA and other anti-corruption laws. The SEC has said that the investigation is a non-public, fact-finding inquiry and we are not aware that any conclusion has been reached by the SEC. Management has initiated an internal review to identify materials that are responsive to the SEC’s inquiry and are actively cooperating in the SEC’s review by providing the information requested.
