NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. CORPORATE STRUCTURE AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations

The unaudited condensed consolidated financial statements are composed of Ciner Resources LP (the “Partnership,” “CINR,” “Ciner Resources,” “we,” “us,” or “our”), a publicly traded Delaware limited partnership, and its consolidated subsidiary, Ciner Wyoming LLC (“Ciner Wyoming”), which is in the business of mining trona ore to produce soda ash. The Partnership’s operations consist solely of its investment in Ciner Wyoming. The Partnership was formed in April 2013 by Ciner Wyoming Holding Co. (“Ciner Holdings”), a wholly-owned subsidiary of Ciner Resources Corporation (“Ciner Corp”). Ciner Corp is a direct wholly-owned subsidiary of Ciner Enterprises Inc. (“Ciner Enterprises”), which is a direct wholly-owned subsidiary of WE Soda Ltd., a U.K. corporation (“WE Soda”). WE Soda is a direct wholly-owned subsidiary of KEW Soda Ltd., a U.K. corporation (“KEW Soda”), which is a direct wholly-owned subsidiary of Akkan Enerji ve Madencilik Anonim Şirketi (“Akkan”). Akkan is directly and wholly owned by Turgay Ciner, the Chairman of the Ciner Group (“Ciner Group”), a Turkish conglomerate of companies engaged in energy and mining (including soda ash mining), media and shipping markets. The Partnership owns a controlling interest comprised of 51.0% membership interest in Ciner Wyoming. All of our soda ash processed is sold to various domestic and international customers including American Natural Soda Ash Corporation (“ANSAC”), which was an affiliate for export sales in 2020. As a result of terminating Ciner Corp’s membership in ANSAC effective as of the end of day on December 31, 2020, ANSAC is no longer an affiliate of the Partnership. All mining and processing activities of Ciner Wyoming take place in one facility located in the Green River Basin of Wyoming.

Basis of Presentation and Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) applicable to interim period financial statements and reflect all adjustments, consisting of normal recurring accruals, which are necessary for fair presentation of the results of operations, financial position and cash flows for the periods presented. All intercompany transactions, balances, revenue and expenses have been eliminated in consolidation. The results of operations for the three month periods ended March 31, 2021 and 2020 are not necessarily indicative of the operating results for the full year.
These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes to audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2020 (the “2020 Annual Report”) filed with the United States Securities and Exchange Commission on March 16, 2021. There have been no material changes in the significant accounting policies followed by us during the three months ended March 31, 2021 from those disclosed in the 2020 Annual Report.
Non-controlling interests

NRP Trona LLC, a wholly-owned subsidiary of Natural Resource Partners L.P. ("NRP"), currently owns a 49.0% membership interest in Ciner Wyoming. NRP’s membership interest in Ciner Wyoming is reflected as the non-controlling interest in the Partnership’s financial results.
        
Use of Estimates
The preparation of these unaudited condensed consolidated financial statements, in accordance with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the dates of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Furthermore, we considered the impact of the COVID-19 pandemic on the use of estimates and assumptions used for financial reporting. While our production is considered “essential” COVID-19 continued to disrupt our customers and customer segments, which had a negative impact on the demand for our products which adversely affected our operations. As of March 31, 2021, as we cannot predict the duration or the scope of the COVID-19 pandemic and its impact on our operations, the potential negative financial impact to our results cannot be reasonably estimated but could be material. As a result of these uncertainties, actual results could differ from those estimates and assumptions. If the economy or markets in which we operate remain weaker than pre-COVID-19 levels, our business, financial condition and results of operations may be further materially and adversely impacted.

Subsequent Events

Table of Contents

We have evaluated subsequent events through the filing date of this Quarterly Report on Form 10-Q.
Recently Issued Accounting Pronouncements and Securities and Exchange Commission Rules
Securities and Exchange Commission Rules
On October 31, 2018, the SEC issued a final rule that amends the current disclosure regime for SEC registrants with material mining operations. Among the final rule’s amendments is the addition of Subpart 1300 to SEC Regulation S-K. The purpose of the amendments is to provide investors with more comprehensive information while aligning the SEC’s disclosure requirements with the global regulatory standards outlined by the Committee for Mineral Reserves International Reporting Standards, which is commonly referred to as “CRIRSCO.” When assessing the materiality of mining operations to determine whether disclosures are required, registrants must consider operations in the aggregate (including all mining properties irrespective of the current stage of development or operation) and evaluate both quantitative and qualitative factors. Registrants must comply with the revised requirements for their first fiscal year beginning on or after January 1, 2021. Further, the disclosures required under the final rule must be supported by the work of a qualified person, such as a mine engineer. When a registrant first reports mineral reserves or resources, or makes a material change to such disclosures, it must file a technical report summary supporting the disclosure. Developing this detailed disclosure information (e.g., by using an expert) and maintaining appropriate disclosure controls and procedures over it will require significant time, resources, and effort. The Partnership continues to evaluate the impact this guidance will have on its disclosures in the Annual Report on Form 10-K for the year ended December 31, 2021.
Recent Accounting Guidance Not Yet Adopted
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”) providing temporary guidance to ease the potential burden in accounting for reference rate reform primarily resulting from the discontinuation of the London Inter-bank Offered Rate (“LIBOR”), which was expected to occur on December 31, 2021. The amendments in ASU 2020-04 are elective and apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The new guidance provides the following optional expedients: (i) simplifies accounting analyses under current GAAP for contract modifications; (ii) simplifies the assessment of hedge effectiveness and allows hedging relationships affected by reference rate reform to continue; and (iii) allows a one-time election to sell or transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform. An entity may elect to apply the amendments prospectively from March 12, 2020 through December 31, 2022 by accounting topic. The Partnership continues to evaluate ASU 2020-04 but does not expect a material impact to the Partnership’s consolidated financial statements.
In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope (“ASU 2021-01”) to clarify that all derivative instruments affected by changes to the interest rates used for discounting, margining or contract price alignment (commonly referred to as the discounting transition) are in the scope of ASC 848. The amendments also clarify other aspects of the guidance in ASC 848 and addresses the effects of the cash compensation adjustment provided in the discounting transition on certain aspects of hedge accounting. The guidance in ASC 848 also allows entities to make a one-time election to sell and/or transfer to available for sale or trading any held-to-maturity debt securities that refer to an interest rate affected by reference rate reform and were classified as held to maturity before January 1, 2020. The original guidance and the recently issued ASU are effective as of their issuance dates. The relief provided is temporary and generally cannot be applied to contract modifications that occur after December 31, 2022 or hedging relationships entered into or evaluated after that date. However, the FASB has indicated that it will revisit the sunset date in ASC 848 after the LIBOR administrator makes a final decision on a phaseout date. The LIBOR administrator recently extended the publication of the overnight and the one-, three-, six- and 12-month USD LIBOR settings through June 30, 2023, when many existing contracts that reference LIBOR will have expired. The Partnership continues to evaluate ASU 2021-01 but does not expect a material impact to the Partnership’s consolidated financial statements.

2. NET INCOME PER UNIT AND CASH DISTRIBUTION
Allocation of Net Income
Net income per unit applicable to limited partners is computed by dividing limited partners’ interest in net income attributable to Ciner Corp, after deducting the general partner’s interest and any incentive distributions, by the weighted average number of outstanding common units. Our net income is allocated to the general partner and limited partners in accordance with their respective partnership percentages, after giving effect to priority income allocations for incentive distributions, if any, to our general partner, pursuant to our partnership agreement. Earnings in excess of distributions are allocated to the general partner and limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income allocations used in the calculation of net income per unit.
In addition to the common units, we have also identified the general partner interest and incentive distribution rights (“IDRs”) as participating securities and use the two-class method when calculating the net income per unit applicable to limited partners, which is based on the weighted-average number of common units outstanding during the period. Anti-dilutive units outstanding were

Quarterly Distribution
Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders, and we have no legal obligation to do so.
In an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, on August 3, 2020, each of the members of the board of managers of Ciner Wyoming approved a suspension of quarterly distributions to its members. In addition, effective August 3, 2020, in connection with the quarterly distribution for the quarter ended June 30, 2020, each of the members of the board of directors of our general partner approved a suspension of quarterly distributions to our unitholders.
Each of the board of managers of Ciner Wyoming and the board of directors of our general partner has approved the continuation of the suspension of quarterly distributions to the members of Ciner Wyoming and our unitholders, as applicable, for each of the quarters ended September 30, 2020, December 31, 2020 and March 31, 2021 in a continued effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic.
In March 2021, the board of managers of Ciner Wyoming approved a special $8.0 million distribution to, amongst other things, provide the Partnership with funds to retire the Ciner Resources Credit Facility.
Management and the board of directors of our general partner will continue to evaluate, on a quarterly basis, whether it is appropriate to reinstate a distribution to our unitholders, which will be dependent in part on our cash reserves, liquidity, total debt levels and anticipated capital expenditures.
General Partner Interest and Incentive Distribution Rights
Our partnership agreement provides that our general partner initially will be entitled to 2.0% of all distributions that we make prior to our liquidation. Our general partner has the right, but not the obligation, to contribute up to a proportionate amount of capital to us in order to maintain its 2.0% general partner interest if we issue additional units. Our general partner’s approximate 2.0% interest, and
9

Table of Contents

the percentage of our cash distributions to which our general partner is entitled from such approximate 2.0% interest, will be proportionately reduced if we issue additional units in the future (other than the issuance of common units upon a reset of the IDRs), and our general partner does not contribute a proportionate amount of capital to us in order to maintain its approximate 2.0% general partner interest. Our partnership agreement does not require that our general partner fund its capital contribution with cash. It may, instead, fund its capital contribution by contributing to us common units or other property.
IDRs represent the right to receive increasing percentages (13.0%, 23.0% and 48.0%) of quarterly distributions from operating surplus after we have achieved the minimum quarterly distribution and the target distribution levels. Our general partner currently holds the IDRs, but may transfer these rights separately from its general partner interest, subject to certain restrictions in our partnership agreement.
Percentage Allocations of Distributions from Operating Surplus
The following table illustrates the percentage allocations of distributions from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under the column heading "Marginal Percentage Interest in Distributions" are the percentage interests of our general partner and the unitholders in any distributions from operating surplus we distribute up to and including the corresponding amount in the column "Total Quarterly Distribution per Unit Target Amount." The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution also apply to quarterly distribution amounts that are less than the minimum quarterly distribution. Under our partnership agreement, our general partner has considerable discretion to determine the amount of available cash (as defined therein) for distribution each quarter to the Partnership’s unitholders, including discretion to establish cash reserves that would limit the amount of available cash eligible for distribution to the Partnership’s unitholders for any quarter. The Partnership does not guarantee that it will pay the target amount of the minimum quarterly distribution listed below (or any distributions) on its units in any quarter. The percentage interests set forth below for our general partner (1) include a 2.0% general partner interest, (2) assume that our general partner has contributed any additional capital necessary to maintain its 2.0% general partner interest, (3) assume that our general partner has not transferred its IDRs and (4) assume that we do not issue additional classes of equity securities.

Ciner Wyoming Equipment Financing Arrangement
On March 26, 2020, Ciner Wyoming and Banc of America Leasing & Capital, LLC, as lender (the “Equipment Financing Lender”), entered into an equipment financing arrangement (the “Ciner Wyoming Equipment Financing Arrangement”) including a Master Loan and Security Agreement, dated as of March 25, 2020 (as amended, the “Master Agreement”) and an Equipment Security Note Number 001, dated as of March 25, 2020 (the “Initial Secured Note”), which provides the terms and conditions for the debt financing of certain equipment related to Ciner Wyoming’s new natural gas-fired turbine co-generation facility that became operational in March 2020. Each equipment financing under the Ciner Wyoming Equipment Financing Arrangement will be evidenced by the execution of one or more equipment notes (including the Initial Secured Note) that incorporate the terms and conditions of the Master Agreement (each, an “Equipment Note”). In order to secure the payment and performance of Ciner Wyoming’s obligations under the Ciner Wyoming Equipment Financing Arrangement and other debt obligations owed by Ciner Wyoming to the Equipment Financing Lender, Ciner Wyoming granted to the Equipment Financing Lender a continuing security interest in all of Ciner Wyoming’s right, title and interest in and to the Equipment (as defined in the Master Agreement) and certain related collateral.
The Ciner Wyoming Equipment Financing Arrangement (1) incorporates all covenants in the Ciner Wyoming Credit Facility (as defined below), now or hereinafter existing, or in any applicable replacement credit facility accepted in writing by the Equipment Financing Lender, that are based upon a specified level or ratio relating to assets, liabilities, indebtedness, rentals, net worth, cash flow, earnings, profitability, or any other accounting-based measurement or test, and (2) includes customary events of default subject to applicable grace periods, including, among others, (i) payment defaults, (ii) certain mergers or changes in control of Ciner Wyoming, (iii) cross defaults with certain other indebtedness (a) to which the Equipment Financing Lender is a party or (b) to third parties in excess of $10 million, and (iv) the commencement of certain insolvency proceedings or related events identified in the Master Agreement. Upon the occurrence of an event of default, in its discretion, the Equipment Financing Lender may exercise certain remedies, including, among others, the ability to accelerate the maturity of any Equipment Note such that all amounts thereunder will become immediately due and payable, to take possession of the Equipment identified in any Equipment Note, and to charge Ciner Wyoming a default rate of interest on all then outstanding or thereafter incurred obligations under the Ciner Wyoming Equipment Financing Arrangement.
Among other things, the Initial Secured Note:
•    has a principal amount of $30,000,000;
•    has a maturity date of March 26, 2028;
11

Table of Contents

•    shall be payable by Ciner Wyoming to the Equipment Financing Lender in 96 consecutive monthly installments of principal and interest commencing on April 26, 2020 and continuing thereafter until the maturity date of the Initial Secured Note, which shall be in the amount of approximately $307,000 for the first 95 monthly installments and approximately $4,307,000 for the final monthly installment; and
•    entitles Ciner Wyoming to prepay all (but not less than all) of the outstanding principal balance of the Initial Secured Note (together with all accrued interest and other charges and amounts owed thereunder) at any time after one (1) year from the date of the Initial Secured Note, subject to Ciner Wyoming paying to the Equipment Financing Lender an additional prepayment amount determined by the amount of principal balance prepaid and the date such prepayment is made.
In connection with the Second Ciner Wyoming Amendment (as defined below), the Master Agreement was amended to incorporate, among other things, the modified covenants set forth in the Second Ciner Wyoming Amendment related to consolidated leverage ratios of Ciner Wyoming.
Ciner Wyoming’s balance under the Ciner Wyoming Equipment Financing Arrangement as of March 31, 2021 was $27.0 million ($26.8 million net of financing costs).
In connection with the event of default (the “Facilities Agreement Default”) under the Facilities Agreement (as defined below) that arose in February 2021 (as defined and described below in the WE Soda and Ciner Enterprises Facilities Agreement section), Ciner Wyoming entered into a second amendment to the Master Agreement (the “Second Amendment to the Master Agreement”) on March 5, 2021. Such amendment modified the definition of change of control under the Master Agreement in order to prevent an event of default thereunder that could have otherwise resulted from the Facilities Agreement lenders foreclosing on certain equity interests in Ciner Holdings (the “Equity Default Remedy”) as a remedy for the Facilities Agreement Default, or as a remedy for future events of default under the Facilities Agreement. Management is not aware of any current circumstances that would result in an event of default under the Ciner Wyoming Equipment Financing Arrangement in the next twelve months. As of March 31, 2021, Ciner Wyoming was in compliance with all financial covenants of the Ciner Wyoming Equipment Financing Arrangement, as amended.
Ciner Wyoming Credit Facility
On August 1, 2017, Ciner Wyoming entered into a Credit Agreement (as amended, the “Ciner Wyoming Credit Facility” and together with the Ciner Wyoming Equipment Financing Arrangement, the “Ciner Wyoming Debt Agreements”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, National Association (“PNC Bank”), as administrative agent, swing line lender and a Letter of Credit (“L/C”) issuer. The Ciner Wyoming Credit Facility is a $225.0 million senior revolving credit facility with a syndicate of lenders, which will mature on the fifth anniversary of the closing date of such credit facility. The Ciner Wyoming Credit Facility provides for revolving loans to fund working capital requirements, and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Ciner Wyoming Credit Facility has an accordion feature that allows Ciner Wyoming to increase the available revolving borrowings under the facility by up to an additional $75.0 million, subject to Ciner Wyoming receiving increased commitments from existing lenders or new commitments from new lenders and the satisfaction of certain other conditions. In addition, the Ciner Wyoming Credit Facility includes a sublimit up to $20.0 million for same-day swing line advances and a sublimit up to $40.0 million for letters of credit.
In addition, the Ciner Wyoming Credit Facility contains various covenants and restrictive provisions that limit (subject to certain exceptions) Ciner Wyoming’s ability to:
•make distributions on or redeem or repurchase units;
•incur or guarantee additional debt;
•make certain investments and acquisitions;
•incur certain liens or permit them to exist;
•enter into certain types of transactions with affiliates of Ciner Wyoming;
•merge or consolidate with another company; and
•transfer, sell or otherwise dispose of assets.
The Ciner Wyoming Credit Facility contains events of default customary for transactions of this nature, including (i) failure to make payments required under the Ciner Wyoming Credit Facility, (ii) failure to comply with covenants and financial ratios in the Ciner Wyoming Credit Facility, (iii) the occurrence of a change of control, (iv) the institution of insolvency or similar proceedings against Ciner Wyoming and (v) the occurrence of a default under any other material indebtedness Ciner Wyoming may have. Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the Ciner Wyoming Credit Facility, the administrative agent shall, at the request of the Required Lenders (as defined in the Ciner Wyoming Credit Facility), or may, with the consent of the Required Lenders, terminate all outstanding commitments under the Ciner Wyoming Credit Facility and
12

Table of Contents

may declare any outstanding principal of the Ciner Wyoming Credit Facility debt, together with accrued and unpaid interest, to be immediately due and payable.
Under the Ciner Wyoming Credit Facility, a change of control is triggered if Ciner Corp and its wholly-owned subsidiaries, directly or indirectly, cease to own all of the equity interests, or cease to have the ability to elect a majority of the board of directors (or similar governing body) of our general partner (or any entity that performs the functions of the Partnership’s general partner). In addition, a change of control would be triggered if the Partnership ceases to own at least 50.1% of the economic interests in Ciner Wyoming or ceases to have the ability to elect a majority of the members of Ciner Wyoming’s board of managers.
Loans under the Ciner Wyoming Credit Facility bear interest at Ciner Wyoming’s option at either:
•a Base Rate, which equals the highest of (i) the federal funds rate in effect on such day plus 0.50%, (ii) the administrative agent’s prime rate in effect on such day or (iii) one-month LIBOR plus 1.0%, in each case, plus an applicable margin; or
•the Eurodollar Rate plus an applicable margin; provided, that with respect to an applicable loan, if the Eurodollar Rate has ceased or will cease to be provided, if the regulatory supervisor for the administrator of the Eurodollar Rate or a governmental authority having jurisdiction over the administrative agent determine that the Eurodollar Rate is no longer representative or if the administrative agent determines that similar U.S. dollar-denominated credit facilities are being executed or modified to incorporate or adopt a new benchmark interest rate to replace the Eurodollar Rate, the administrative agent and Ciner Wyoming may establish an alternative interest rate for the applicable loan.
The Ciner Wyoming Credit Facility has an interest rate floor of 0.50%.
The unused portion of the Ciner Wyoming Credit Facility is subject to a per annum commitment fee and the applicable margin of the interest rate under the Ciner Wyoming Credit Facility will be determined as follows:

Pricing Tier	Leverage Ratio	Eurodollar Rate Loans	Base Rate
Loans	Commitment
Fee	
1	< 1.25:1.0	1.500%	0.500%	0.250%	
2	≥ 1.25:1.0 but < 1.75:1.0	1.750%	0.750%	0.275%	
3	≥ 1.75:1.0 but < 2.25:1.0	2.000%	1.000%	0.300%	
4	≥ 2.25:1.0 but < 3.00:1.0	2.250%	1.250%	0.375%	
5	≥ 3.00:1.0 but < 3.50:1.0	2.500%	1.500%	0.375%	
6	≥ 3.50:1.0 but < 4.00:1.0	2.750%	1.750%	0.425%	
7	≥ 4.00:1.0	3.000%	2.000%	0.475%	
In connection with the Facilities Agreement Default, Ciner Wyoming entered into a Third Amendment to the Ciner Wyoming Credit Facility (the “Third Amendment”) in order to prevent an event of default thereunder that could have otherwise resulted from the Facilities Agreement lenders exercising the Equity Default Remedy as a remedy for the Facilities Agreement Default, or a future event of default under the Facilities Agreement. Such amendment (i) modified the definition of change of control to exclude any change in control that could arise from lender actions under the Facilities Agreement relating to any events of default under the Facilities Agreement; (ii) reduced the leverage ratio to 3.00 to 1.00 for the quarter ended June 30, 2021 and each fiscal quarter thereafter (from amendments prior to the Third Amendment, a leverage ratio of 4.50 to 1.0 or lower was required for the quarter ended March 31, 2021 and an interest coverage ratio of not less than 3.00 to 1.0 is required); and (iii) added a covenant that any borrowings under the Wyoming Credit Facility are secured by substantially all of Ciner Wyoming’s personal property, subject to certain exclusions. Management is not aware of any current circumstances that would result in an event of default under the Ciner Wyoming Credit Facility in the next twelve months. As of March 31, 2021, Ciner Wyoming was in compliance with all financial covenants of the Ciner Wyoming Credit Facility.
Ciner Resources Credit Facility
On August 1, 2017, the Partnership entered into a Credit Agreement (as amended, the “Ciner Resources Credit Facility”) with each of the lenders listed on the respective signature pages thereof and PNC Bank, as administrative agent, swing line lender and an L/C issuer. The Ciner Resources Credit Facility was a $10.0 million senior secured revolving credit facility with a syndicate of lenders, that would have matured on the fifth anniversary of the closing date of such credit facility. The Ciner Resources Credit Facility provided for revolving loans to be available to fund distributions on the Partnership’s units and working capital requirements and capital expenditures, to consummate permitted acquisitions and for all other lawful partnership purposes. The Ciner Resources Credit Facility included a sublimit up to $5.0 million for same-day swing line advances and a sublimit up to $5.0 million for letters of credit. The Partnership’s obligations under the Ciner Resources Credit Facility were guaranteed by each of the Partnership’s material domestic subsidiaries other than Ciner Wyoming. In addition, the Partnership’s obligations under the Ciner Resources Credit Facility were secured by a pledge of substantially all of the Partnership’s assets (subject to certain exceptions), including the membership interests held in Ciner Wyoming by the Partnership.

On March 8, 2021, the Partnership terminated the Ciner Resources Credit Facility; the Partnership repaid in full its obligations thereunder.
WE Soda and Ciner Enterprises Facilities Agreement
Ciner Enterprises, the entity that indirectly owns and controls the Partnership, has a credit agreement and certain related finance documents, to which WE Soda and Ciner Enterprises (as borrowers), and KEW Soda, WE Soda, WE Soda Kimya Yatırımları Anonim Şirketi, Ciner Kimya Yatırımları Sanayi ve Ticaret Anonim Şirketi, Ciner Enterprises, Ciner Holdings and Ciner Corp (as original guarantors and together with the borrowers, the “Ciner Obligors”), are parties (as amended and restated or otherwise modified, the “Facilities Agreement”). The Facilities Agreement expires on August 1, 2025.
Even though neither we nor Ciner Wyoming are a party or a guarantor under the Facilities Agreement while any amounts are outstanding under the Facilities Agreement we will be indirectly affected by certain affirmative and restrictive covenants that apply to WE Soda and its subsidiaries (which include us). Besides the customary covenants and restrictions, the Facilities Agreement includes provisions that, without a waiver or amendment approved by lenders, whose commitments are more than 66-2/3% of the total commitments under the Facilities Agreement to undertake such action, would (i) prevent certain transactions (including loans) with our affiliates, including such transactions that could reasonably be expected to materially and adversely affect the interests of certain finance parties, (ii) restrict the ability to amend our limited partnership agreement or the general partner’s limited liability company agreement or our other constituency documents if such amendment could reasonably be expected to materially and adversely affect the interests of the lenders to the Facilities Agreement, (iii) restrict the amount of our capital expenditures if certain ratios are not achieved by the Ciner Obligors thereunder and (iv) prevent actions that enable certain restrictions or prohibitions on our ability to upstream cash (including via distributions) to the borrowers under the Facilities Agreement. Based on the Ciner Obligors’ applicable ratios currently, the Partnership’s expansion capital expenditures are prohibited until the Ciner Obligors’ applicable ratios are at specified levels pursuant to the Facilities Agreement.  
In addition, Ciner Enterprises’ ownership in Ciner Holdings is subject to a lien under the Facilities Agreement, which enables the lenders under the Facilities Agreement to foreclose on such collateral and take control of Ciner Holdings, which controls the general partner of the Partnership, if any of the borrowers or guarantors under the Facilities Agreement are unable to satisfy its respective obligations under the Facilities Agreement.
In February 2021, Ciner Wyoming was informed that an event of default under the Facilities Agreement arose and that the Ciner Obligors were working with the Facilities Agreement lenders to resolve this Facilities Agreement Default. Absent resolution, the Facilities Agreement lenders have the right to foreclose on the equity interest in Ciner Holdings. In order to prevent an event of default under each of the Ciner Wyoming Debt Agreements, which could have otherwise resulted from the Facilities Agreement lenders exercising their Equity Default Remedy, Ciner Wyoming entered into the Second Amendment to the Master Agreement and the Third Amendment to the Ciner Wyoming Credit Facility to modify the related definitions of change of control as described above. Furthermore, we terminated the Ciner Resources Credit Facility and repaid in full our obligations thereunder. As of March 31, 2021 WE Soda and Ciner Enterprises were not in compliance with the Facilities Agreement; however, effective April 19, 2021 they secured a waiver subject to satisfaction of certain conditions that must be fulfilled by June 30, 2021.

6. EMPLOYEE COMPENSATION
The Partnership participates in various benefit plans offered and administered by Ciner Corp and is allocated its portions of the annual costs related thereto. The specific plans are as follows:
Retirement Plans - Benefits provided under the Pension Plan (the “Retirement Plan”) are based upon years of service and average compensation for the highest 60 consecutive months of the employee’s last 120 months of service, as defined. The Retirement Plan covers substantially all full-time employees hired before May 1, 2001. Ciner Corp’s Retirement Plan had a net liability balance of $53.1 million and $55.1 million as of March 31, 2021 and December 31, 2020, respectively. Ciner Corp’s current funding policy is to contribute an amount within the range of the minimum required and the maximum tax-deductible contribution. The Partnership’s allocated portion of the Retirement Plan’s net periodic pension benefits for the three months ended March 31, 2021 and 2020 were a benefit of $0.8 million and $0.4 million, respectively. The increase in the amount of benefit recognized during the three months ended March 31, 2021 was driven by asset changes from the prior period.
Savings Plan - The 401(k) retirement plan (the “401(k) Plan”) covers all eligible hourly and salaried employees. Eligibility is limited to all domestic residents and any foreign expatriates who are in the United States indefinitely. The 401(k) Plan permits employees to contribute specified percentages of their compensation, while the Partnership makes contributions based upon specified percentages of employee contributions. Participants hired on or subsequent to May 1, 2001, will receive an additional contribution from the Partnership based on a percentage of the participant’s base pay. Contributions made to the 401(k) Plan for the three months ended March 31, 2021 and 2020 were $1.6 million and $1.6 million, respectively.
Postretirement Benefits - Most of the Partnership’s employees hired prior to May 1, 2017 are eligible for postretirement benefits other than pensions if they reach retirement age while still employed.
The postretirement benefits are accounted for by Ciner Corp on an accrual basis over an employee’s period of service. The postretirement plan, excluding pensions, are not funded, and Ciner Corp has the right to modify or terminate the plan. The Ciner Corp post-retirement plan had a net unfunded liability of $13.0 million and $13.1 million as of March 31, 2021 and December 31, 2020, respectively.
The Partnership’s allocated portion of postretirement costs for the three months ended March 31, 2021 and 2020 were $0.2 million and $0.2 million, respectively.

7. EQUITY - BASED COMPENSATION
In July 2013, our general partner established the Ciner Resource Partners LLC 2013 Long-Term Incentive Plan (as amended to date, the “Plan” or “LTIP”). Historically, the Plan was intended to provide incentives that will attract and retain valued employees, officers, consultants and non-employee directors by offering them a greater stake in our success and a closer identity with us, and to encourage ownership of our common units by such individuals. The Plan provides for awards in the form of common units, phantom units, distribution equivalent rights (“DERs”), cash awards and other unit-based awards.
All employees, officers, consultants and non-employee directors of us and our parents and subsidiaries are eligible to be selected to participate in the Plan. As of March 31, 2021, subject to further adjustment as provided in the Plan, a total of 0.7 million common units were available for awards under the Plan. Any common units tendered by a participant in payment of the tax liability with respect to an award, including common units withheld from any such award, will not be available for future awards under the Plan. Common units awarded under the Plan may be reserved or made available from our authorized and unissued common units or from common units reacquired (through open market transactions or otherwise). Any common units issued under the Plan through the assumption or substitution of outstanding grants from an acquired company will not reduce the number of common units available for awards under the Plan. If any common units subject to an award under the Plan are forfeited, any common units counted against the number of common units available for issuance pursuant to the Plan with respect to such award will again be available for awards under the Plan. The Partnership has made a policy election to recognize forfeitures as they occur in lieu of estimating future forfeiture activity under the Plan.
Non-employee Director Awards
There were no grants of non-employee director awards during the three months ended March 31, 2021, and  2020, respectively.
Time Restricted Unit Awards
We grant restricted unit awards in the form of common units to certain employees that vest over a specified period of time, usually between one to three years, with vesting based on continued employment as of each applicable vesting date. Award recipients are
15

Table of Contents

entitled to distributions subject to the same restrictions as the underlying common unit. The awards are classified as equity awards, and are accounted for at fair value at grant date.
The following table presents a summary of activity on the Time Restricted Unit Awards:

(1) Determined by dividing the aggregate grant date fair value of awards by the number of common units.

Total Return Performance Unit Awards
Historically, we have granted TR Performance Unit Awards to certain employees. The TR Performance Unit Awards represent the right to receive a number of common units at a future date based on the achievement of market-based performance requirements in accordance with the TR Unit Performance Award agreement, and also include Distribution Equivalent Rights (“DERs”). DERs are the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued upon vesting. The TR Performance Unit Awards vest at the end of the performance period, usually between two to three years from the date of the grant. Performance is measured on the achievement of a specified level of total return, or TR, relative to the TR of a peer group comprised of other limited partnerships. The potential payout ranges from 0-200% of the grant target quantity and is adjusted based on our total return performance relative to the peer group. For purposes of the table below the number of units are included at target quantity.
We utilized a Monte Carlo simulation model to estimate the grant date fair value of TR Performance Unit Awards granted to employees, adjusted for market conditions. This type of award requires the input of highly subjective assumptions, including expected volatility and expected distribution yield. Historical and implied volatilities were used in estimating the fair value of these awards.
The following table presents a summary of activity on the TR Performance Unit Awards:

	Three Months Ended

2019 Performance Unit Awards
On September 23, 2019, the board of directors of our general partner approved a new form of performance unit award to be granted based upon the achievement of certain financial, operating and safety-related performance metrics (“2019 Performance Unit Awards”) pursuant to our LTIP, and the vesting of the 2019 Performance Unit Awards is linked to a weighted average consisting of internal performance metrics defined in the 2019 Performance Unit Award agreement (the “Performance Metrics”) during a three-year performance period (the “Measurement Period”). The vesting of the 2019 Performance Unit Awards, and number of common units of the Partnership distributable pursuant to such vesting, is dependent on our performance relative to a pre-established budget over the Measurement Period; provided, that the awardee remains continuously employed with our general partner or its affiliates or satisfies other service-related criteria through the end of the Measurement Period, except in certain cases of Changes in Control (as defined in our LTIP) or the awardee’s death or disability.
Vested 2019 Performance Unit Awards will be settled in our common units, with the number of such common units payable under the award for a given year in the Measurement Period to be calculated by multiplying the target number provided in the corresponding
16

Table of Contents

2019 Performance Unit Award agreement by a payout multiplier, which may range from 0%-200% in each case, as determined by aggregating the corresponding weighted average assigned to the Performance Metrics. The 2019 Performance Unit Awards also contain DERs and entitle the recipient the right to receive an amount equal to the accumulated cash distributions made during the period with respect to each common unit issued. Upon vesting of the 2019 Performance Unit Awards, the award recipient is entitled to receive a cash payment equal to the sum of the distribution equivalents accumulated with respect to vested 2019 Performance Unit Awards during the period beginning on January 1, 2019 and ending on the applicable vesting date. The 2019 Performance Unit Awards granted to award recipients during 2019 have a performance cycle that began on January 1, 2019 and will end on December 31, 2021.
The following table presents a summary of activity on the 2019 Performance Unit Awards for the period:

9. COMMITMENTS AND CONTINGENCIES
From time to time we are party to various claims and legal proceedings related to our business. Although the outcome of these proceedings cannot be predicted with certainty, management does not currently expect any of the legal proceedings we are involved in to have a material effect on our business, financial condition and results of operations. We cannot predict the nature of any future claims or proceedings, nor the ultimate size or outcome of such proceedings and whether any damages resulting from them will be covered by insurance.

Off-Balance Sheet Arrangements
We have historically been subject to a self-bond agreement (the “Self-Bond Agreement”) with the Wyoming Department of Environmental Quality (“WDEQ”) under which we committed to pay directly for reclamation costs. In May 2019, the State of Wyoming enacted legislation that limits our and other mine operators’ ability to self-bond and required us to seek other acceptable financial instruments to provide alternate assurances for our reclamation obligations by November 2020. We provided such alternate assurances by timely securing a third-party surety bond effective October 15, 2020 (the “Surety Bond”) for the then-applicable full self-bond amount $36.2 million, which was also the amount of our obligation as of December 31, 2020. After we secured the Surety Bond, the previous Self-Bond Agreement was terminated. As of the date of this Report, the impact on our net income and liquidity due to securing the Surety Bond has been immaterial and we anticipate that to continue to be the case. The amount of such assurances that we are required to provide is subject to change upon periodic re-evaluation by the WDEQ’s Land Quality Division. As a result of the most recent such periodic re-evaluation, the Surety Bond amount was increased to $41.8 million effective March 1, 2021.

10. AGREEMENTS AND TRANSACTIONS WITH AFFILIATES
Agreements and transactions with affiliates collectively have a significant impact on the Partnership’s financial statements because the Partnership is a subsidiary in a global group structure. Agreements directly between the Partnership and other affiliates, or indirectly between affiliates that the Partnership does not control, can have a significant impact on recorded amounts or disclosures in the Partnership's financial statements, including any commitments and contingencies between the Partnership and affiliates, or potentially, third parties.
Ciner Corp was the exclusive sales agent for the Partnership and through its membership in ANSAC, through December 31, 2020, Ciner Corp has responsibility for promoting and increasing the use and sale of soda ash and other refined or processed sodium products produced. Through December 31, 2020, ANSAC served as the primary international distribution channel for the Partnership and two other U.S. manufacturers of trona-based soda ash. ANSAC operated on a cooperative service-at-cost basis to its members such that typically any annual profit or loss is passed through to the members. As previously disclosed as part of its strategic initiative to gain better direct access and control of international customers and logistics and the ability to leverage the expertise of Ciner Group, the world’s largest natural soda ash producer, effective as of the end of day on December 31, 2020, Ciner Corp exited ANSAC (the “ANSAC termination date”). In connection with the exit settlement agreement with ANSAC, among other things, there are sales commitments to ANSAC in 2021 and 2022 where Ciner Corp continues to sell, at substantially lower volumes, product to ANSAC for export sales purposes, with a fixed rate per ton selling, general and administrative expense, and also purchases a limited amount of export logistics services in 2021. Through in part the Partnership’s affiliates, the Partnership has amongst other things: (i) obtained its own international customer sales arrangements for 2021, (ii) obtained third-party export port services, and (iii) chartered and executed its own international product delivery. For the three months ended March 31, 2021, the total charges for export sales, marketing and logistic services obtained from other Ciner affiliates were approximately $0.2 million.
Historically, by design and prior to Ciner Corp’s exit from ANSAC, ANSAC managed most of our international sales, marketing and logistics, and as a result, was our largest customer for the year ended December 31, 2020, accounting for 45.4%, of our net sales. Although ANSAC has historically been our largest customer, the impact of Ciner Corp’s exit from ANSAC on our net sales, net income and liquidity appears to be limited. We made this determination primarily based upon the belief that we would continue to be one of the lowest cost producers of soda ash in the global market. With a low-cost position combined with better direct access and control of our customers and logistics and the ability to leverage Ciner Group’s expertise in these areas, we believe we have been able to adequately replace these net ANSAC sales. Since January 1, 2021, Ciner Corp has been managing the Partnership’s sales and marketing activities for exports. Ciner Corp has leveraged the distributor network established by Ciner Group and independent third-party distribution partners to optimize our reach into each market.
As a result of terminating Ciner Corp’s membership in ANSAC, ANSAC is no longer an affiliate of the Partnership as of the ANSAC termination date.
Post-ANSAC International Export Capabilities
In accordance with the ANSAC Early Exit Agreement, Ciner Corp began marketing soda ash on our behalf directly into international markets and building its international sales, marketing and supply chain infrastructure. We now have access to utilize the distribution network that has already been established by the global Ciner Group. We believe that by having the option of combining our volumes with Ciner Group’s soda ash exports from Turkey, Ciner Corp’s strategic exit from ANSAC has helped us leverage global Ciner Group’s, the world’s largest natural soda ash producer, soda ash operations which we expect will improve our ability to optimize our market share both domestically and internationally. Being able to work with the global Ciner Group provides us with the opportunity to better attract and more efficiently serve larger global customers. In addition, the Partnership is working to enhance its international logistics infrastructure that includes, among other things, a domestic port for export capabilities. These export capabilities are being developed by an affiliated company and options being evaluated range from continued outsourcing in the near term to developing its own port capabilities in the longer term.
Selling, general and administrative expenses also include amounts charged to the Partnership by its affiliates principally consisting of salaries, benefits, office supplies, professional fees, travel, rent and other costs of certain assets used by the Partnership. On October 23, 2015, the Partnership entered into a Services Agreement (the “Services Agreement”) with our general partner and Ciner Corp. Pursuant to the Services Agreement, Ciner Corp has agreed to provide the Partnership with certain corporate, selling, marketing, and general and administrative services, in return for which the Partnership has agreed to pay Ciner Corp an annual management fee and reimburse Ciner Corp for certain third-party costs incurred in connection with providing such services. In addition, under the limited liability company agreement governing Ciner Wyoming, Ciner Wyoming reimburses us for employees who operate our assets and for support provided to Ciner Wyoming. These transactions do not necessarily represent arm's length transactions and may not represent all costs if Ciner Wyoming operated on a standalone basis.
As a result of terminating Ciner Corp’s membership in ANSAC, ANSAC is no longer an affiliate of the Partnership as of the ANSAC termination date. The following tables include transactions with ANSAC as an affiliate for the three months ended March 31, 2020

11. MAJOR CUSTOMERS AND SEGMENT REPORTING
Our operations are similar in geography, nature of products we provide, and type of customers we serve. As the Partnership earns substantially all of its revenues through the sale of soda ash mined at a single location, we have concluded that we have one operating segment for reporting purposes.
The net sales by geographic area are as follows:

Total net sales	$	127.8 			$	114.4 		

12. FAIR VALUE MEASUREMENTS
Financial instruments consist primarily of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, derivative financial instruments and long-term debt. The carrying amounts of cash and cash equivalents, accounts receivable and accounts payable and accrued expenses approximate their fair value because of the nature of such instruments. Our long-term debt and derivative financial instruments are measured at their fair values with inputs based on quoted market values for similar but not identical financial instruments.
Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis
Derivative Financial Instruments
We have interest rate swap contracts, designated as cash flow hedges, to mitigate our exposure to possible increases in interest rates. The swap contracts consist of three individual $12.5 million swaps with an aggregate notional value of $37.5 million at both March 31, 2021 and December 31, 2020. The swaps outstanding as of March 31, 2021 have various maturities through 2023.
We enter into natural gas forward contracts, designated as cash flow hedges, to mitigate volatility in the price of natural gas related to a portion of the natural gas we consume. These contracts generally have various maturities through 2024. These contracts had an aggregate notional value of $23.0 million and $25.9 million as of March 31, 2021 and December 31, 2020, respectively.
The following table presents the fair value of derivative assets and derivative liabilities and the respective locations as of March 31, 2021 and December 31, 2020:

Financial Assets and Liabilities not Measured at Fair Value
The carrying value of our long-term debt materially reflects the fair value of our long-term debt as its key terms are similar to indebtedness with similar amounts, durations and credit risks. See Note 4 “Debt” for additional information on our debt arrangements.

13. SUBSEQUENT EVENTS
Suspension of Distributions
Effective May 3, 2021, the board of managers of Ciner Wyoming unanimously approved a continuation of the suspension of quarterly distributions to the members of Ciner Wyoming. Effective May 3, 2021, in connection with the quarterly distribution for the quarter ended March 31, 2021, each of the members of the board of directors of our general partner approved a continuation of the suspension of quarterly distributions to our unitholders in order to increase financial and liquidity flexibility as the COVID-19 pandemic continues.
Management and the board of directors of our general partner will continue to evaluate, on a quarterly basis, whether it is appropriate to reinstate a distribution to our unitholders, which will be dependent in part on our cash reserves, liquidity, total debt levels and anticipated capital expenditures.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following management's discussion and analysis of financial condition and results of operations in conjunction with the historical unaudited condensed consolidated financial statements, and notes thereto, included elsewhere in this Report.
Cautionary Statements Regarding Forward-Looking Statements
This Report contains, and our other public filings and oral and written statements by us and our management may include, statements that constitute “forward-looking statements” within the meaning of the United States securities laws. Forward-looking statements include the information concerning our possible or assumed future results of operations, reserve estimates, business strategies, financing plans, competitive position, potential growth opportunities, potential operating performance, the effects of competition and the effects of future legislation or regulations. Forward-looking statements include all statements that are not historical facts and may be identified by the use of forward-looking terminology such as the words “believe,” “expect,” “plan,” “intend,” “anticipate,” “estimate,” “predict,” “forecast,” “project,” “potential,” “continue,” “may,” “will,” “could,” “should,” or the negative of these terms or similar expressions. Examples of forward-looking statements include, but are not limited to, statements concerning cash available for distribution and future distributions, if any, and such distributions are subject to the approval of the board of directors of our general partner and will be based upon circumstances then existing. We have based our forward-looking statements on management’s beliefs and assumptions and on information currently available to us.
Forward-looking statements involve risks, uncertainties and assumptions. You are cautioned not to place undue reliance on any forward-looking statements. Actual results may vary materially. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements and, therefore, affect our ability to distribute cash to unitholders, include:
•the market prices for soda ash in the markets in which we sell;
•the volume of natural and synthetic soda ash produced worldwide;
•domestic and international demand for soda ash in the flat glass, container glass, detergent, chemical and paper industries in which our customers operate or serve;
•the freight costs we pay to transport our soda ash to customers or various delivery points;
•the cost of electricity and natural gas used to power our operations;
•the amount of royalty payments we are required to pay to our lessors and licensor and the duration of our leases and license;
•political disruptions in the markets we or our customers serve, including any changes in trade barriers;
•our relationships with our customers and our sales agent’s ability to renew contracts on favorable terms to us;
•the creditworthiness of our customers;
•a cybersecurity event;
•the short and long-term impact of the COVID-19 pandemic, including the impact of government orders on our employees, suppliers, customers and operations;
•the impact of the ANSAC exit and our transition to the utilization of Ciner Group’s global distribution network for some of our export operations beginning on January 1, 2021;
•regulatory action affecting the supply of, or demand for, soda ash, our ability to mine trona ore, our transportation logistics, our operating costs or our operating flexibility;
•new or modified statutes, regulations, governmental policies and taxes or their interpretations; and
•prevailing U.S. and international economic conditions and foreign exchange rates.
In addition, the actual amount of cash we will have available for distribution will depend on other factors, some of which are beyond our control, including, among other things:
•the level and timing of capital expenditures we make;
24

Table of Contents

•the level of our operating, maintenance and general and administrative expenses, including reimbursements to our general partner for services provided to us;
•the cost of acquisitions, if any;
•our debt service requirements and other liabilities;
•fluctuations in our working capital needs;
•our ability to borrow funds and access capital markets;
•restrictions on distributions contained in debt agreements to which we, Ciner Wyoming or our affiliates are a party;
•the amount of cash reserves established by our general partner;
•our ability to reinstate distributions in the future; and
•other business risks affecting our cash levels.
These factors should not be construed as exhaustive and we urge you to carefully consider the risks described in this Report, our most recent Annual Report on Form 10-K, and subsequent reports filed with the United States Securities and Exchange Commission (the “SEC”). You may obtain these reports from the SEC’s website at www.sec.gov. All forward-looking statements included in this Report are expressly qualified in their entirety by these cautionary statements. Unless required by law, we undertake no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise.

Recent Developments
COVID-19
The global COVID-19 pandemic continues to cause certain disruptions to the economy throughout the world, including the United States and markets to which our products have historically been exported. There have been extraordinary actions taken by international, federal, state, and local public health and governmental authorities to contain and combat the outbreak and spread of COVID-19 in regions throughout the world, including travel bans, quarantines, “stay-at-home” orders, and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations. Vaccines for COVID-19 became first available on a limited basis in late December 2020. They are becoming more available globally and all U.S. adults are now eligible for the vaccine.
Our Response to COVID-19
25

Table of Contents

We continue to closely monitor the impact of the outbreak of COVID-19 and all governmental actions in response thereto on all aspects of our business, including how it impacts our customers, employees, supply chain, distribution network and cash flows. We have taken strong proactive steps to keep the safety of our team and their families as the priority. We have been executing and continue to execute a comprehensive plan to help prevent the spread of the virus in our work locations and it appears to be having a positive impact. This plan includes multiple layers of protection for our employees, including but not limited to, social distancing, working from home for certain employees, splitting shifts, increased sanitation, restricted contractor and visitor access, temperature checks on all contractors and third-party vendors, travel restrictions, mask wearing requirements, and daily communication with our teams. We have conducted proactive quarantining and contact tracing from the early days of this pandemic and require self-reporting of any illness, in addition to a company doctor, weekly status meetings, tracking local resources, and industry wide efforts. We have also prepared strong contingency plans for all our operations with specific actions based on absentee rates. While we have not utilized any such plans to date as they have not been needed, they are continuously refined in case needed. As COVID-19 vaccines become more broadly available, we encourage employees to get vaccinated. We anticipate a re-opening of societies when the virus plateaus and diminishes, and we have completed re-entry plans to implement as they become appropriate. We are relying on science and data to guide our decisions related to COVID-19. Our focus prior to and during this pandemic has been the safety of our teams and this will continue to be our priority as we scale our operations back to normal as the data guides us to do so. We continue to actively monitor and adhere to applicable local, state, federal, and international governmental guideline actions to better ensure the safety of our employees.
The impact of COVID-19
In the first half of 2020 and primarily in the beginning of the second quarter of 2020, we saw a decline in demand due to the COVID-19 pandemic adversely impacting our sales and production volume, and price per ton; but, in the second half of 2020, we saw the signs of recovery on our operations domestically as well as internationally in the form of increased global demand, notwithstanding certain pricing pressure. We experienced fluctuations in quarter over quarter soda ash volume sold of 4.4% decline, 35.7% decline, 26.7% increase, and 9.5% increase in the first, second, third and fourth quarters of 2020, compared to the immediately preceding quarter respectively. During the first quarter of 2021, we saw continued recovery in both domestic and international business. The soda ash volume sold in the first quarter of 2021 increased 21.7% over the fourth quarter of 2020.
Although the number of individuals who have been vaccinated has increased, certain states and countries have again begun to see a plateau or upward daily trend of new COVID-19 confirmed cases. At this time, we cannot predict the duration or the scope of the COVID-19 pandemic and its impact on our operations, and the potential negative financial impact to our results cannot be reasonably estimated but could be material. We are actively managing the business to maintain cash flow, and we believe we have enough liquidity to meet our anticipated liquidity requirements.
For the three months ended March 31, 2021, we have incurred $0.6 million in costs directly related to COVID-19 primarily in the form of costs related to employee safety and retention and additional inventory storage and logistics costs. For the three months ended March 31, 2020, however, we incurred no such costs directly related to COVID-19.
Termination of Membership in ANSAC
As previously disclosed as part of its strategic initiative to gain better direct access and control of international customers and logistics and the ability to leverage the expertise of Ciner Group, the world’s largest natural soda ash producer, effective as of the end of day on December 31, 2020, Ciner Corp exited ANSAC. In connection with the settlement agreement with ANSAC, there are sales commitments to ANSAC in 2021 and 2022 where Ciner Corp will continue to sell, at substantially lower volumes, product to ANSAC for export sales purposes, with a fixed rate per ton selling, general and administrative expense, and will also purchase a limited amount of export logistics services in 2021. Through this transition, the Partnership has amongst other things: (i) obtained its own international customer sales arrangements for 2021, (ii) obtained third-party export port services, and (iii) chartered and executed its own international product delivery.
Although ANSAC has historically been our largest customer, we anticipate that the impact of Ciner Corp’s exit from ANSAC on our net sales, net income and liquidity is limited. We made this determination primarily based upon the belief that we will continue to be one of the lowest cost producers of soda ash in the global market. With a low-cost position combined with more direct access and better control of our international customers and logistics and the ability to leverage Ciner Group’s expertise in these areas, we believe we will adequately replace these net ANSAC sales. Since January 1, 2021, Ciner Corp has managed the Partnership’s sales and marketing activities for exports with the ANSAC exit being complete. Ciner Corp has leveraged the distributor network established by Ciner Group and independent third-party distribution partners to optimize our reach into each market.
Suspension of Distributions
Our general partner has considerable discretion in determining the amount of available cash, the amount of distributions and the decision to make any distribution. Although our partnership agreement requires that we distribute all of our available cash quarterly, there is no guarantee that we will make quarterly cash distributions to our unitholders, and we have no legal obligation to do so.
26

Table of Contents

In an effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic, on August 3, 2020, each of the members of the board of managers of Ciner Wyoming approved a suspension of quarterly distributions to its members. In addition, effective August 3, 2020, in connection with the quarterly distribution for the quarter ended June 30, 2020, each of the members of the board of directors of our general partner approved a suspension of quarterly distributions to our unitholders.
Each of the board of managers of Ciner Wyoming and the board of directors of our general partner has approved the continuation of the suspension of quarterly distributions to the members of Ciner Wyoming and our unitholders, as applicable, for each of the quarters ended September 30, 2020, December 31, 2020 and March 31, 2021 in a continued effort to achieve greater financial and liquidity flexibility during the COVID-19 pandemic.
In March 2021, the board of managers of Ciner Wyoming approved a special $8.0 million distribution to, amongst other things, provide the Partnership with funds to retire the Ciner Resources Credit Facility.
Management and the board of directors of our general partner will continue to evaluate, on a quarterly basis, whether it is appropriate to reinstate a distribution to our unitholders, which will be dependent in part on our cash reserves, liquidity, total debt levels and anticipated capital expenditures.

Factors Affecting Our Results of Operations
Soda Ash Supply and Demand
Our net sales, earnings and cash flow from operations are primarily affected by the global supply of, and demand for, soda ash, which, in turn, directly impacts the prices that we and other producers charge for our products.
Historically, long-term demand for soda ash in the United States has been driven in large part by general economic growth and activity levels in the end-markets that the glass-making industry serves, such as the automotive and construction industries. Long-term soda ash demand in international markets has grown in conjunction with Gross Domestic Product. We expect that over the long-term, future global economic growth will positively influence global demand, which will likely result in increased exports, primarily from the United States, Turkey and to a limited extent, from China, the largest suppliers of soda ash to international markets. Currently, and in the near- and mid-term, we expect that COVID-19 will continue to have a certain impact across a variety of our customers and customer segments which will have a negative impact on demand for our products. Our international demand was impacted the most as different countries continue to deal with different levels of the outbreak and shutdowns, but showed signs of recovery internationally during the second half of 2020. The soda ash volume sold to domestic customers increased 24.7% and 8.7% in the third quarter and the fourth quarter of 2020 compared to the second and third quarter of 2020, respectively. The soda ash volume sold to international customers increased 28.4% and 10.1% in the third quarter and the fourth quarter of 2020 compared to the second and third quarter of 2020, respectively. The soda ash volume sold to international customers increased 23.8% in the first quarter of 2021 compared to the fourth quarter of 2020. While we continue to see signs of recovery from the COVID-19 related impact on our industry, we have yet to recover to pre-COVID-19 levels especially for international sales. During the first quarter of 2021, the soda ash volume sold to domestic customers and international customers was 32.9% higher and 5.1% lower, respectively than that of the first quarter of 2020. We have been able to utilize the flexibility of our production assets to adjust to the COVID-19 uncertainties and customers’ demands, but the Partnership may experience declines in the near- and mid-term if the COVID-19 pandemic worsens.
Sales Mix
We will adjust our sales mix based upon what is the best margin opportunity for the business between domestic and international. Our operations have been and continue to be sensitive to fluctuations in freight and shipping costs and changes in international prices, which have historically been more volatile than domestic prices. Our gross profit will be impacted by the mix of domestic and international sales as a result of changes in logistics costs and our average selling prices.
International Export Capabilities
As previously disclosed, Ciner Corp exited ANSAC, effective as of the end of day on December 31, 2020 as part of its strategic initiative to gain more direct access to and better control of international customers and logistics, and to leverage the expertise of Ciner Group, the world’s largest natural soda ash producer. In connection with the settlement agreement with ANSAC, Ciner Corp will continue to sell in 2021 and 2022, at substantially lower volumes, product to ANSAC for export sales purposes, with a fixed rate per ton selling, general and administrative expense, and will also purchase a limited amount of export logistics services in 2021. Through this transition, the Partnership has, amongst other things: (i) obtained its own international customer sales arrangements for 2021, (ii) obtained third-party export port services, and (iii) chartered and executed its own international product delivery.
Although ANSAC has historically been our largest customer, we anticipate that the impact of Ciner Corp’s exit from ANSAC on our net sales, net income and liquidity is limited. We made this determination primarily based upon the belief that we will continue to be one of the lowest cost producers of soda ash in the global market. With a low-cost position combined with more direct access and better control of our international customers and logistics and the ability to leverage Ciner Group’s expertise in these areas, we believe we will adequately replace these net ANSAC sales. Since January 1, 2021, Ciner Corp has managed the Partnership’s sales and

marketing activities for exports with the ANSAC exit being complete. Ciner Corp has leveraged the distributor network established by Ciner Group and independent third-party distribution partners to optimize our reach into each market.
Energy Costs
One of the primary impacts to our profitability is our energy costs. Because we depend upon natural gas and electricity to power our trona ore mining and soda ash processing operations, our net sales, earnings and cash flow from operations are sensitive to changes in the prices we pay for these energy sources. Our cost of energy, particularly natural gas, has been relatively low in recent years, and, despite the historic volatility of natural gas prices, we believe that we will continue to benefit from relatively low prices in the near future. However, we expect to continue to hedge a portion of our forecasted natural gas purchases to mitigate volatility. We completed the construction of a new natural gas-fired turbine co-generation facility and started its operation in March 2020. The facility is designed to provide roughly one-third of our electricity and steam demands at our mine in the Green River Basin. The new co-generation facility in a normal production environment, is expected to save us approximately $3.0 million to $4.0 million annually in energy costs.

How We Evaluate Our Business
Productivity of Operations
Our soda ash production volume is primarily dependent on the following three factors: (1) operating rate, (2) quality of our mined trona ore and (3) recovery rates. Operating rate is a measure of utilization of the effective production capacity of our facility and is determined in large part by productivity rates and mechanical on-stream times, which is the percentage of actual run times over the total time scheduled. We implement two planned outages of our mining and surface operations each year, typically in the second and third quarters. During these outages, which are scheduled to last approximately one week each, we repair and replace equipment and parts. Periodically, we may experience minor unplanned outages or unplanned extensions to planned outages caused by various factors, including equipment failures, power outages or service interruptions. The quality of our mine ore is determined by measuring the trona ore recovered as a percentage of the deposit, which includes both trona ore and insolubles. Plant recovery rates are generally determined by calculating the soda ash produced divided by the sum of the soda ash produced plus soda ash that is not recovered from the process. All of these factors determine the amount of trona ore we require to produce one short ton of soda ash and liquor, which we refer to as our “ore to ash ratio.” Our ore to ash ratio was 1.65: 1.0 and 1.53: 1.0 for the three months ended March 31, 2021 and 2020, respectively.
Freight and Logistics
The soda ash industry is logistics intensive and involves careful management of freight and logistics costs. These freight costs make up a large portion of the total delivered cost to the customer. Delivery costs to most domestic customers and ANSAC primarily relate to rail freight services. Some domestic customers may elect to arrange their own freight and logistic services. Delivered costs to non-ANSAC international customers primarily consists of both rail freight services to the port of embarkation and the additional ocean freight to the port of disembarkation. With our exit from ANSAC, as we expected, our gross freight costs and related sales prices have increased as a result of our directly managing our international operations, including ocean freight export logistics.
We utilize one railroad company for the majority of the domestic rail freight services that we receive. For the three months ended March 31, 2021, we shipped over 90% of our soda ash to our customers initially via a single rail line owned and controlled by the railroad company. Our plant receives rail service exclusively from the railroad company and shipments by rail accounted for over 60% and over 80% of our total freight costs for the three months ended March 31, 2021 and 2020, respectively. The decrease in the percentage of freight that is related to the railroad company is due primarily to the increased ocean freight associated with the start up in the three months ended March 31, 2021 of direct international sales and their respective delivery locations. Our agreement with the railroad company expires on December 31, 2021 and there can be no assurance that it will be renewed on terms favorable to us or at all.
If we do not ship at least a significant portion of our soda ash production on the railroad company’s rail line during a twelve-month period, we must pay the railroad company a shortfall payment under the terms of our transportation agreement. For the three months ended March 31, 2021, we assisted the majority of our domestic customers in arranging their freight services. During 2020 and the three months ended March 31, 2021, we had no shortfall payments and do not expect to make any such payments in the future. In addition, for the three months ended March 31, 2021 we had one additional company that represented more than 10% of our freight costs.
Net Sales
Net sales include the amounts we earn on sales of soda ash. We recognize revenue from our sales when we satisfy the performance obligation defined in the contract with the customer. The performance obligation for domestic sales is typically met when goods are delivered to the carrier for shipment, which is the point at which the customer has the ability to direct the use of and obtain substantially all remaining benefits from the asset. The time at which delivery and transfer of title occurs, for the majority of our contracts with customers, is the point when the product leaves our facilities, thereby rendering our performance obligation fulfilled. Since January 1, 2021, sales to ANSAC have been fulfilled when delivered to ANSAC facilities. The performance obligation for international sales is typically satisfied when goods are loaded onto the vessel for shipment at the port of loading. Substantially all of our sales are derived from sales of soda ash, which we sell through our exclusive sales agent, Ciner Corp. A small amount of our sales is derived from sales of production purge, which is a by-product liquor solution containing soda ash that is produced during the processing of trona ore. For the purposes of our discussion below, we include these transactions in domestic sales of soda ash and in the volume of domestic soda ash sold.
Sales prices for sales through ANSAC include the cost of freight to the ports of embarkation for overseas export or to Laredo, Texas for sales to Mexico. Sales prices for other international sales may include the cost of rail freight to the port of embarkation, the cost of ocean freight to the port of disembarkation for import by the customer and the cost of inland freight required for delivery to the customer.
Cost of products sold
29

Table of Contents

Expenses relating to employee compensation, energy, including natural gas and electricity, royalties and maintenance materials constitute the greatest components of cost of products sold. These costs generally increase in line with increases in sales volume.
Energy. A major item in our cost of products sold is energy, comprised primarily of natural gas and electricity. We primarily use natural gas to fuel our above-ground processing operations, including the heating of calciners, and we use electricity to power our underground mining operations, including our continuous mining machines, or continuous miners, and shuttle cars. The monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices, over the past five years, have ranged between $1.29 and $5.70. The average monthly Northwest Pipeline Rocky Mountain Index natural gas settlement prices for the three months ended March 31, 2021 and 2020 were $3.01 and $2.22 per MMBtu, respectively. However, we expect to continue to hedge a portion of our forecasted natural gas purchases to mitigate volatility. In order to mitigate the risk of gas price fluctuations, we hedge a portion of our forecasted natural gas purchases by entering into physical or financial gas hedges generally ranging between 20% and 80% of our expected monthly gas requirements, on a sliding scale, for approximately the next four years. During the first quarter of 2020, we completed the construction of a new natural gas-fired turbine co-generation facility that is expected to provide roughly one-third of our electricity and steam demands at our mine in the Green River Basin. The new co-generation facility in a normal production environment is expected to provide us with a savings of approximately $3.0 million to $4.0 million annually in energy costs.
Employee Compensation. See Part I, Item 1. Financial Statements - Note 6, “Employee Compensation” for information on the various benefit plans offered and administered by Ciner Corp.
Royalties. During the three months ended March 31, 2021, we paid royalties to the State of Wyoming, the U.S. Bureau of Land Management and Sweetwater Royalties LLC. The royalties are calculated based upon a percentage of the value of soda ash and related products sold at a certain stage in the mining process. These royalty payments may be subject to a minimum domestic production volume from our Green River Basin facility. We are also obligated to pay annual rentals to our lessors and licensor regardless of actual sales. In addition, we pay a production tax to Sweetwater County, and trona severance tax to the State of Wyoming that is calculated based on a formula that utilizes the volume of trona ore mined and the value of the soda ash produced.
The royalty rates we pay to our lessors and licensor may change upon our renewal or renegotiation of such leases and license. On June 28, 2018, Ciner Wyoming amended its License Agreement, dated July 18, 1961 (the “License Agreement”), with a predecessor in interest to Sweetwater Royalties LLC, to, among other things, (i) extend the term of the License Agreement to July 18, 2061 and for so long thereafter as Ciner Wyoming continuously conducts operations to mine and remove sodium minerals from the licensed premises in commercial quantities; and (ii) set the production royalty rate for each sale of sodium mineral products produced from ore extracted from the licensed premises at eight percent (8%) of the net sales of such sodium mineral products. Any increase in the royalty rates we are required to pay to our lessors and licensor, or any failure by us to renew any of our leases and license, could have a material adverse impact on our results of operations, financial condition or liquidity, and, therefore, may affect our ability to distribute cash to unitholders. On December 11, 2020, the Secretary of the Interior authorized an industry-wide royalty reduction from currently set rates by establishing a 2% federal royalty rate for a period of ten years for all existing and future federal soda ash or sodium bicarbonate leases. This change by the Secretary of the Interior reduces the rates on our mineral leases with the U.S. Government from 6% to 2% as of January 1, 2021 and for the following ten years. Due to the rate reduction on our mineral leases with the U.S. Government, our savings on royalty fees has been approximately $1.6 million based on our mining operations in the three months ended March 31, 2021.
Selling, general and administrative expenses
Selling, general and administrative expenses incurred by our affiliates on our behalf are allocated to us based on the time the employees of those companies spend on our business and the actual direct costs they incur on our behalf. Until December 31, 2020, selling, general and administrative expenses incurred by ANSAC on our behalf were allocated to us based on the proportion of ANSAC’s total volumes sold for a given period attributable to the soda ash sold by us to ANSAC. Pursuant to the ANSAC Exit agreement, we incur a fixed rate of selling, general, and administrative expense for each ton we sell to ANSAC. The Partnership has a Services Agreement (the “Services Agreement”), with our general partner and Ciner Corp. Pursuant to the Services Agreement, Ciner Corp provides the Partnership with certain corporate, selling, marketing, and general and administrative services. In return the Partnership pays Ciner Corp an annual management fee, subject to quarterly adjustments, and reimburses Ciner Corp for certain third-party costs incurred in connection with providing such services. In addition, under the joint venture agreement governing Ciner Wyoming, Ciner Wyoming reimburses us for employees who operate our assets and for support provided to Ciner Wyoming.
Ciner Group also owns and operates port facilities in Turkey, and, since 2017, one of its other North American subsidiaries has an arrangement to exclusively import soda ash into a port on the U.S east coast. Ciner Corp, which is the exclusive sales agent for the Partnership, also serves as the exclusive sales agent of that material and receives a commission on those sales. We believe by having access to that material, Ciner Corp is able to offer its customers an improved level of service, greater certainty of supply to the Partnership’s end customers, and as a result lower its overall costs to serve, which are subsequently charged to the Partnership.

First Quarter 2021 Financial Highlights:
•Net sales of $127.8 million increased 11.7% for the three months ended March 31, 2021 from $114.4 million for the three months ended March 31, 2020. The overall improvement in soda ash sales volume for the three months ended March 31, 2021 was attributable to global recovery of soda ash demand from the impact of COVID-19. We have seen our export volume steadily increase since the second quarter of 2020. We operated closer to full production capacity in the first quarter of 2021 for the first time since the COVID-19 pandemic started. Sales prices in the three months ended March 31, 2021 have not fully recovered to pre-pandemic levels.
•Soda ash volume produced decreased 4.7% from the prior-year first quarter, and soda ash volume sold increased 8.5% from the prior-year first quarter. During the first quarter of 2021, the volume sold increased due to certain soda ash market’s recovery from COVID-19 pandemic.
•Net income of $5.6 million decreased $8.6 million from the prior-year first quarter. The decrease is primarily due to a change in new customer mix including new customers with lower margin which was still impacted by the overall global soda ash pricing not yet fully recovered to the pre-COVID-19 level in the first quarter of 2020.
•Adjusted EBITDA of $15.7 million decreased 29.9% from the prior-year first quarter. The decrease is primarily due to a change in new customer mix including new customers with lower margin which was still impacted by the overall global soda ash pricing not yet fully recovered to the pre-COVID-19 level in the first quarter of 2020.
•Basic earnings per unit of $0.12 for the quarter decreased 64.7% over the prior-year first quarter of $0.34.
•Net cash used in operating activities of $6.4 million decreased 138.3% over prior-year first quarter net cash provided in operating activities of $16.7 million.
•Distributable cash flow of $4.7 million decreased 47.8% compared to the prior-year first quarter.
•The distribution coverage ratio was not applicable and 1.32 for the three months ended March 31, 2021 and 2020, respectively. There were no distributions in the first quarter of 2021.

Three Months Ended March 31, 2021 compared to Three Months Ended March 31, 2020
Consolidated Results
Net sales. Net sales increased by 11.7% to $127.8 million for the three months ended March 31, 2021 from $114.4 million for the three months ended March 31, 2020, primarily driven by an increase in soda ash volumes sold of 8.5% due to higher domestic demand for the three months ended March 31, 2021, as compared to the three months ended March 31, 2020. The overall improvement in soda ash sales volume for the three months ended March 31, 2021 was attributable to global recovery of soda ash demand from the impact of COVID-19. We have seen our export volume steadily increase since the second quarter of 2020. We operated closer to full production capacity in the first quarter of 2021 for the first time since the COVID-19 pandemic started. Sales prices in the three months ended March 31, 2021 have not fully recovered to pre-pandemic levels.
Cost of products sold. Cost of products sold, including depreciation, depletion and amortization expense and freight costs, increased by 23.8% to $115.3 million for the three months ended March 31, 2021 from $93.1 million for the three months ended March 31, 2020, which were primarily due to increases in ocean freight cost for the international sales. The increase in ocean freight cost resulted from a volatile vessel market impacted by the disruptions in the recent global supply chains.
Selling, general and administrative expenses.  Our selling, general and administrative expenses decreased 3.4% to $5.6 million for the three months ended March 31, 2021, compared to $5.8 million for the three months ended March 31, 2020. The decrease was driven primarily by the decrease in the equity base compensation expenses and in the three months ended March 31, 2020 we recognized larger accounts receivable credit loss expense due to credit concerns related to certain customers that were negatively impacted by the onset of COVID-19. We incurred $0.4 million of accounts receivable credit loss expense for the first quarter of 2020 but no such expense for the first quarter of 2021.
Operating income. Operating income decreased by 55.5% to $6.9 million for the three months ended March 31, 2021 from $15.5 million for the three months ended March 31, 2020. The decrease is primarily due to a change in new customer mix including new customers with lower margin which was still impacted by the overall global soda ash pricing not yet fully recovered to the pre-COVID-19 level in the first quarter of 2020.

Table of Contents

Net income. As a result of the foregoing, net income decreased by 60.6% to $5.6 million for the three months ended March 31, 2021, from $14.2 million for the three months ended March 31, 2020.

Liquidity and Capital Resources
Sources of liquidity include cash generated from operations and borrowings under credit facilities and capital calls from partners. We use cash and require liquidity primarily to finance and maintain our operations, fund capital expenditures for our property, plant and equipment, make cash distributions to holders of our partnership interests, pay the expenses of our general partner and satisfy obligations arising from our indebtedness. Our ability to meet these liquidity requirements will depend primarily on our ability to generate cash flow from operations.
Our sources of liquidity include:
•cash generated from our operations of which we had cash on hand of $2.7 million as of March 31, 2021;
•approximately $102.5 million ($225.0 million, less $122.5 million outstanding) is available for borrowing and undrawn under the Ciner Wyoming Credit Facility (as defined herein) as of March 31, 2021 (during the three months ended March 31, 2021, the Ciner Wyoming Credit Facility experienced repayments of $15.0 million, offset by borrowings of $35.0 million); and
We continue to analyze all aspects of our spending in order to maintain liquidity at levels we believe are necessary. We expect our ongoing working capital and capital expenditures to be funded by cash generated from operations and borrowings under the Ciner Wyoming Credit Facility and the Ciner Wyoming Equipment Financing Arrangement (as defined herein). We are planning to refinance the Ciner Wyoming Credit Facility in the third quarter before it will be classified in short term liabilities. We are closely reviewing maintenance capital expenditures at our Wyoming facility to adequately maintain the physical assets at the Wyoming facility. In addition, we are subject to business and operational risks that could adversely affect our cash flow, access to borrowings under the Ciner Wyoming Credit Facility, and ability to make monthly installment payments under the Ciner Wyoming Equipment Financing Arrangement. Our ability to satisfy debt service obligations, to fund planned capital expenditures and to make acquisitions will depend upon our future operating performance, which, in turn, will be affected by prevailing economic conditions, our business and other factors, some of which are beyond our control.
We are actively managing the business to maintain cash flow and we believe we have taken steps to have adequate liquidity to meet our anticipated requirements during the COVID-19 pandemic. As we cannot predict the duration or scope of the COVID-19 pandemic and its impact on our operations, the potential negative financial impact to our results cannot be reasonably estimated but could be material to the Partnership. We believe our existing liquidity, the steps we have taken to strengthen our financial position and the suspension of our quarterly distributions since the second quarter of 2020, provide the financial flexibility and sufficient liquidity to run our business effectively. We will review and, when appropriate, adjust our overall approach to capital allocation and liquidity as we know more about how the post-pandemic recovery will unfold. See Part I, Item 2, Overview, “Recent Developments,” for more information.

Capital Requirements
Working capital is the amount by which current assets exceed current liabilities. Our working capital requirements have been, and will continue to be, primarily driven by changes in accounts receivable and accounts payable, which generally fluctuate with changes in volumes, contract terms and market prices of soda ash in the normal course of our business. Other factors impacting changes in accounts receivable and accounts payable could include the timing of collections from customers and payments to suppliers, as well as the level of spending for maintenance and growth capital expenditures. A material adverse change in operations or available financing under the Ciner Wyoming Credit Facility could impact our ability to fund our requirements for liquidity and capital resources. Historically, we have not made working capital borrowings to finance our operations. As of March 31, 2021, we had a working capital balance of $129.4 million as compared to a working capital balance of $109.3 million as of December 31, 2020. The primary driver for the increase in our working capital balance was due to the startup of direct sales to international customers who typically have longer payment terms compared to the recent payment history from ANSAC, which, prior to December 31, 2020, managed international sales for the Partnership.
Financial Assurance Regulatory Updates by the Wyoming Department of Environmental Quality
We have historically been subject to a self-bond agreement (the “Self-Bond Agreement”) with the Wyoming Department of Environmental Quality (“WDEQ”) under which we committed to pay directly for reclamation costs. In May 2019, the State of Wyoming enacted legislation that limits our and other mine operators’ ability to self-bond and required us to seek other acceptable financial instruments to provide alternate assurances for our reclamation obligations by November 2020. We provided such alternate assurances by timely securing a third-party surety bond effective October 15, 2020 (the “Surety Bond”) for the then-applicable full self-bond amount $36.2 million, which was also the amount of our obligation as of December 31, 2020. After we secured the Surety Bond, the previous Self-Bond Agreement was terminated. As of the date of this Report, the impact on our net income and liquidity due
34

Table of Contents

to securing the Surety Bond has been immaterial and we anticipate that to continue to be the case. The amount of such assurances that we are required to provide is subject to change upon periodic re-evaluation by the WDEQ’s Land Quality Division. As a result of the most recent such periodic re-evaluation, the Surety Bond amount was increased to $41.8 million effective March 1, 2021. For a discussion of risks in connection with future legislation relating to such financial assurances that could affect our business, financial condition and liquidity, please read Item IA, “Risk Factors--Risks Inherent in our Business and Industry--Our inability to acquire, maintain or renew financial assurances related to the reclamation and restoration of mining property could have a material adverse effect on our business, financial condition and results of operations,” in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 16, 2021.

Capital Expenditures
Our operations require investments to expand, upgrade or enhance existing operations and to meet evolving environmental and safety regulations. We distinguish between maintenance and expansion capital expenditures. Maintenance capital expenditures (including expenditures for the construction or development of new capital assets or the replacement, improvement or expansion of existing capital assets) are made to maintain, over the long-term, our operating income or operating capacity. Examples of maintenance capital expenditures are expenditures to upgrade and replace mining equipment and to address equipment integrity, safety and environmental laws and regulations. Our maintenance capital expenditures do not include actual or estimated capital expenditures for replacement of our trona reserves. Expansion capital expenditures are incurred for acquisitions or capital improvements made to increase, over the long-term, our operating income or operating capacity. Examples of expansion capital expenditures include the acquisition and/or construction of complementary assets to grow our business and to expand existing facilities, such as projects that increase production from existing facilities or reduce costs, to the extent such capital expenditures are expected to increase our long-term operating capacity or operating income.
The table below summarizes our capital expenditures, on an accrual basis:

(1)These capital expenditures for expansion in the three months ended March 31, 2021 were allowed as they are not in the scope of the capital expenditure restrictions defined in the Facilities Agreement.
During the three months ended March 31, 2021, capital expenditures decreased $3.8 million as compared to the three months ended March 31, 2020. The decrease was primarily driven by decreases in expansion capital expenditures because of the completion of our new co-generation facility, which became operational in March 2020. The decrease was partially offset by the continued increase of maintenance capital expenditures at our Wyoming facility to both adequately maintain the facility’s physical assets and to improve its operational reliability.
Green River Expansion Project
We continue to develop plans and execute the early phases for a potential new Green River Expansion Project that we believe will increase production levels up to approximately 3.5 million tons of soda ash per year or up to approximately 135% of the last five-year average of soda ash produced per year. We have conducted the initial basic design and are currently evaluating and pursuing the related permits and detailed cost and market analysis pursuant to the basic design.  This project will require capital expenditures materially higher than have been recently incurred by Ciner Wyoming. When considering the significant investment required by this expansion and the infrastructure improvements designed to increase our overall efficiency, as well as the COVID-19 pandemic’s negative impact on our financial results, we have re-prioritized the timing of the significant expenditure items in order to increase financial and liquidity flexibility until we have more clarity and visibility into the ongoing impact of the COVID-19 pandemic on our business. The timing of the new Green River Expansion Project as well as any other expansion capital expenditures may be impacted by certain performance ratios requirements of the Ciner Obligors’ Facilities Agreement. Based on the Ciner Obligors’ applicable ratios as of December 31, 2020 and March 31, 2021 certain of our expansion capital expenditures are prohibited until the Ciner Obligors’ applicable ratios are at acceptable levels pursuant to the Facilities Agreement. See Part I, Item 1, Financial Statements - Note 4, “Debt,” for details.

Cash Flows Discussion
The following is a summary of cash provided by or used in each of the indicated types of activities:

	Three Months Ended
March 31,		Percent Increase/(Decrease)	
(In millions)	2021		2020			
Cash provided by (used in):	 		 			
Operating activities	$	(6.4)			$	16.7 			(138.3)	%	
Investing activities	$	(5.4)			$	(12.9)			(58.1)	%	
Financing activities	$	14.0 			$	32.7 			(57.2)	%	
Operating Activities
Our operating activities during the three months ended March 31, 2021 used cash of $6.4 million, a decrease of 138.3% from the $16.7 million cash provided during the three months ended March 31, 2020, primarily as a result of the following:
•a decrease of 60.6% in net income of $5.6 million during the three months ended March 31, 2021, compared to $14.2 million for the prior-year period. The decrease is primarily due to a change in new customer mix including new customers with lower margin which was still impacted by the overall global soda ash pricing not yet fully recovered to the pre-COVID-19 level in the first quarter of 2020; and
•$20.9 million of working capital used in operating activities during the three months ended March 31, 2021, compared to $4.4 million of working capital used in operating activities during the three months ended March 31, 2020. The $16.4 million increase in working capital used by operating activities was primarily due to the $34.3 million increase in accounts receivable as of March 31, 2021 compared to that of March 31, 2020, offset by the $8.9 million increase in accounts payable and the $8.0 million increase in inventory as of March 31, 2021 compared to that of March 31, 2020. Due to the startup of direct sales to international customers who typically have longer payment terms, compared to the recent payment history from ANSAC, the accounts receivable balance increased significantly as of March 31, 2021 and contributed to lower cash flows from operating activities during this transition period of three months ended March 31, 2021. We expect this reduction in cash flow to be a one-time impact in the initial quarter that direct sales were made to these new international customers with longer payment terms.
Investing Activities
We used cash flows of $5.4 million in investing activities during the three months ended March 31, 2021, compared to $12.9 million used during the three months ended March 31, 2020, for capital projects as described in “Capital Expenditures” above.
Financing Activities
Net cash provided by financing activities of $14.0 million during the three months ended March 31, 2021 decreased by 57.2% over the prior-year cash provided by financing activities, largely due to $28.8 million less borrowings net of repayments and $3.2 million less distribution in the three months ended March 31, 2021.
Ciner Resources Credit Facility was fully repaid and terminated on March 8, 2021. Borrowings under the Ciner Wyoming Credit Facility were at variable interest rates.

	As of and for the quarter ended	
(Dollars in millions)	March 31, 2021	
Short-term borrowings from banks:		
Outstanding amount at period end	$	122.5 		
Weighted average interest rate at period end(1)	3.23 	%	
Average daily amount outstanding for the period	$	116.2 		
Weighted average daily interest rate for the period(1)	3.09 	%	
Maximum month-end amount outstanding during the period	$	122.5 		

	
(1) Weighted average interest rates set forth in the table above include the impacts of our interest rate swap contracts designated as cash flow hedges. As of March 31, 2021, the interest rate swap contracts had an aggregate notional value of $37.5 million.

Debt
See Part I, Item 1, Financial Statements - Note 4, "Debt" for more information regarding the Partnership’s debt obligations and related disclosures.

Contractual Obligations
During the three months ended March 31, 2021, there were no material changes with respect to the contractual obligations disclosed in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 16, 2021 (the “2020 Annual Report”) other than as described below.
•As discussed in Part I, Item 1, Financial Statements - Note 4, "Debt," on March 8, 2021, we terminated the Ciner Resources Credit Facility and fully repaid the outstanding borrowing amount.
•As of March 31, 2021, borrowings under the Ciner Wyoming Credit Facility increased by $20.0 million from December 31, 2020.

Critical Accounting Policies
There have been no material changes in critical accounting policies followed by us during the three months ended March 31, 2021 from those disclosed in the 2020 Annual Report.

Recently Issued Accounting Standards
Accounting standards recently issued are discussed in Item 1. Financial Statements - Note 1, “Corporate Structure and Summary of Significant Accounting Policies,” in the notes to unaudited condensed consolidated financial statements.

Non-GAAP Financial Measures
We report our financial results in accordance with generally accepted accounting principles in the United States (“GAAP”). We also present the non-GAAP financial measures of:
•Adjusted EBITDA;
•distributable cash flow; and
•distribution coverage ratio.
We define Adjusted EBITDA as net income (loss) plus net interest expense, income tax, depreciation, depletion and amortization, equity-based compensation expense and certain other expenses that are non-cash charges or that we consider not to be indicative of ongoing operations. Distributable cash flow is defined as Adjusted EBITDA less net cash paid for interest, maintenance capital expenditures and income taxes, each as attributable to Ciner Resources LP. The Partnership may fund expansion-related capital expenditures with borrowings under existing credit facilities such that expansion-related capital expenditures will have no impact on cash on hand or the calculation of cash available for distribution.  In certain instances, the timing of the Partnership’s borrowings and/or its cash management practices will result in a mismatch between the period of the borrowing and the period of the capital expenditure.  In those instances, the Partnership adjusts designated reserves (as provided in our partnership agreement) to take account of the timing difference. Accordingly, expansion-related capital expenditures have been excluded from the presentation of cash available for distribution. Distributable cash flow will not reflect changes in working capital balances. We define distribution coverage ratio as the ratio of distributable cash flow as of the end of the period to cash distributions payable with respect to such period.
Adjusted EBITDA, distributable cash flow and distribution coverage ratio are non-GAAP supplemental financial measures that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:
•our operating performance as compared to other publicly traded partnerships in our industry, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;
•the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;
•our ability to incur and service debt and fund capital expenditures; and
•the viability of capital expenditure projects and the returns on investment of various investment opportunities.
We believe that the presentation of Adjusted EBITDA, distributable cash flow and distribution coverage ratio provide useful information to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable
37

Table of Contents

to Adjusted EBITDA and distributable cash flow are net income and net cash provided by operating activities. Our non-GAAP financial measures of Adjusted EBITDA, distributable cash flow and distribution coverage ratio should not be considered as alternatives to GAAP net income, operating income, net cash provided by operating activities, or any other measure of financial performance or liquidity presented in accordance with GAAP. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some, but not all items that affect net income and net cash provided by operating activities. Investors should not consider Adjusted EBITDA, distributable cash flow and distribution coverage ratio in isolation or as a substitute for analysis of our results as reported under GAAP. Because Adjusted EBITDA, distributable cash flow and distribution coverage ratio may be defined differently by other companies, including those in our industry, our definition of Adjusted EBITDA, distributable cash flow and distribution coverage ratio may not be comparable to similarly titled measures of other companies, thereby diminishing its utility.
The table below presents a reconciliation of the non-GAAP financial measures of Adjusted EBITDA and distributable cash flow to the GAAP financial measures of net income and net cash provided by operating activities:

Item 3. Quantitative and Qualitative Disclosures about Market Risk
Our exposure to the financial markets consists of changes in interest rates relative to the balance of our outstanding debt obligations and derivatives that we have employed from time to time to manage our exposure to changes in market interest rates, and commodity prices. We do not use financial instruments or derivatives for trading or other speculative purposes. Our exposure to interest rate risks and commodity price risks is discussed in Part II, Item 7A of our 2020 Annual Report. The uncertainty that exists with respect to the economic impact of the global COVID-19 pandemic has introduced significant volatility in the financial markets. The impacts of such volatility on the Partnership cannot be predicted with confidence or reasonably estimated at this time.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Based on an evaluation of the effectiveness of the design and operation of disclosure controls and procedures, under the supervision and with the participation of the Partnership’s management, the Partnership’s principal executive officer and principal financial officer have concluded that the Partnership’s disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of March 31, 2021 to ensure that information required to be disclosed by the Partnership in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to the Partnership’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting (“ICFR”)
There have not been any changes in the Partnership’s internal control over financial reporting during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

Exhibit 95.1

MINE SAFETY DISCLOSURES

Section 1503 of the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank"), contains reporting requirements regarding coal or other mine safety. We operate a mine in conjunction with our Green River, Wyoming facility, which is subject to regulation by the Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”), and is therefore subject to these reporting requirements. Presented in the table below is information regarding certain mining safety and health citations, orders and violations, if any, which MSHA has issued with respect to our operation as required by Dodd-Frank. In evaluating this information, consideration should be given to the fact that citations and orders can be contested and appealed, and in that process, may be reduced in severity, penalty amount or sometimes dismissed (vacated) altogether.
    
The letters used as column headings in the table below correspond to the explanations provided underneath the table as to the information set forth in each column with respect to the numbers of violations, orders, citations or dollar amounts, as the case may be, during the first calendar quarter of 2021 unless otherwise indicated. All section references in the table below refer to provisions of the Mine Act.
