USAC’s Proposed Economic Price Adjustment Clause [THIS EPA CLAUSE SHALL APPLY SOLELY TO CLIN 0001] C09 Economic Price Adjustment – Department of Labor Index (APR 2024) (a) Warranties. The contractor warrants that— (1) The base unit prices set forth in the Schedule do not include allowances for any portion of the contingency covered by this procurement note; and (2) Prices invoiced shall be computed in accordance with the terms of this procurement note and USAC’s Ingot Pricing Terms. (b) Definitions. As used throughout this procurement note— (1)"Index", for the purpose of price adjustment under this procurement note, means the Antimony Metal Market Price published by Argus Metals Market Report. Antimony Metal Market Price means the price for Antimony Regulus, Grade II (minimum 99.65% Sb) du Rotterdam, as assessed and published by Argus under its Metals Market Report, expressed in U.S. dollars per pound, FOB Rotterdam, on the Date of Price Determination The Argus Metals Market Report is published by Argus Media, a London-based global price-reporting agency (PRA). Argus Media specializes in commodity price benchmarks, market analysis, and industry reporting across energy, petrochemicals, fertilizers, and metals. For metals specifically, Argus provides daily price assessments, market commentary, and forward-looking analysis. Their metals coverage spans base metals, minor metals, ferro-alloys, battery materials, and scrap. Argus Media is the publisher. The “Argus Metals Market Report” is one of their flagship daily reports covering price assessments and market news. Rotterdam = a benchmarked location inside the report and is the benchmark that is used by all parties Offeror conducts business with for procurement and purchasing ore feedstock for processing into antimony products. Rotterdam is not a separate report. It is one of the geographic pricing hubs covered within the Argus Metals Market Report. Argus uses Rotterdam as a key delivery/import/export hub for Europe, especially for minor metals (like antimony, tungsten, cobalt, etc.). When you see references like “Argus antimony Rotterdam price,” it means the price assessment Argus publishes for spot transactions. (2) "Base index" means the arithmetic average of the final version of the indexes published for the N/A months, or N/A quarters for ECI, preceding the closing date for receipt of proposals or the date required for receipt of final proposal revisions, if discussions were held. (3) "Adjusting index" means the arithmetic average of the [ ] first published or [X] final version of the index for the N/A months, or N/A quarters for ECI, prior to the month in which the adjusting contract modification is effective. (4) "Base unit price" means the unit price applicable to a quantity of a contract line item established at contract award, exclusive of any price adjustment pursuant to this procurement note. (5) “Adjustment period” means the period during which a particular adjustment to the unit price under this procurement note (calculated at the beginning of the adjustment period) will apply to a specific Delivery Order. The length of each adjustment period in months is equal to the period of performance of the Delivery Order. (c) Adjustments. Price adjustments will be made upon issuance of each Delivery Order. The contracting officer will obtain a quote from the contractor in accordance with the Ingot Pricing Terms and establish the Contract Price for the Delivery Order in accordance with the Pricing Formula. Once established, the Contracting Price will remain the same for purposes of a Delivery Order for the full term of the Order. The contracting officer will make price adjustments in accordance with this procurement note by issuing a contract modification showing the base unit price, the mathematical calculations, and the changed unit price(s). (1) The contractor shall adjust its price for a Delivery Order if the Contract Price as established by the Ingot Terms Pricing Formula is lower or higher than the starting base of . The Government shall not issue more than 10 Delivery Orders in total over the five-year term of this contract. Accordingly, the Contract Price will not be adjusted more than 10 times over the life of the contract. In the event of unforeseen circumstances, the government may increase the maximum number of orders above 10 orders under the contract, with a corresponding increase in the number of adjustments, subject to the Changes clause and all other terms of this EPA clause. (2) Example of adjustment calculation: See Ingot Pricing Terms *In computing the base and adjusting indexes, the contracting officer will round the resulting figure to the second decimal place. **The contracting officer will round this number to the fifth decimal place.

| CONTINUATION SHEET REFERENCE NO. OF DOCUMENT BEING CONTINUED: CONTINUED ON NEXT PAGE PAGE 7 OF 37 PAGES SP8000-25-D-0007 ***The contracting officer will round all dollar figures to the nearest cent. (d) The aggregate of the increases in any contract unit price under the terms of this procurement note shall not exceed (percent) of the original base unit price, except as provided hereafter. (1) If at any time the contractor has reason to believe that within the near future a price adjustment under the terms of this procurement note will be required that will exceed the adjustment ceiling for any item, the contractor shall promptly notify the contracting officer in writing of the expected increase. The notification shall include a revised ceiling the contractor believes is sufficient to permit completion of remaining contract performance, along with appropriate explanation and documentation as required by the contracting officer. (2) If an increase in the index would raise a contract unit price for an item above the current ceiling, the contracting officer may issue a contract modification to raise the ceiling. If the contracting officer does not raise the contract ceiling, the contracting officer will promptly notify the contractor in writing. (e) Invoices. The basis for prices payable under this contract is the latest adjusted unit price incorporated into the contract as of the date of order. (f) Retroactive adjustment. This paragraph applies only if the contracting officer selected “first published index” in paragraph (b)(3). N/A. If the Government has already paid for orders delivered during an adjustment period, the contractor may request a retroactive adjustment. The contracting officer will, base the retroactive adjustment on the difference between a higher final revised index applicable to an adjustment period and the index values used in calculating the unit price for that adjustment period, subject to the adjustment ceiling in paragraph (d) and under] the following conditions: (1) The request for equitable adjustment clearly establishes that the unit price adjustment for the adjustment period would have been higher if the final revised index had been used; and identifies all invoices and payments to which it applies cites the specific index differences relating to the requested adjustment and provides a calculation of the total net price adjustment for items delivered during that adjustment period. (2) The total dollar changes for items delivered is $N/A ($500.00 unless otherwise stated) or more for the applicable adjustment period(s). (3) The contracting officer received the contractor’s written request within 45 days following publication of the final revised index. The contractor shall adjust its prices downward based on the difference between a lower final revised index applicable to an adjustment period and the index values used in calculating the unit price for that adjustment period, subject to the limitation in paragraph (f)(2). (g) Revision of index. If any applicable index is discontinued or its method of derivation is altered substantially, or if the contracting officer determines that the index consistently and substantially fails to reflect market conditions, the parties shall mutually agree upon an appropriate and comparable substitute. The contracting officer will modify the contract to reflect such substitute effective on the date the index was discontinued, altered, or began to consistently and substantially fail to reflect market conditions. (h) Final invoice. The contractor shall include a statement on the final invoice confirming it has applied all decreases required by this procurement note to the amounts invoiced. (i) Disputes. The “Disputes” clause of the contract applies to any dispute arising under this procurement note. (End of USAC’s Proposed Economic Price Adjustment Clause) USAC’s Proposed Ingot Pricing Terms [for CLIN 0001 – Antimony Metal Ingots, 99.65% Purity (Unit of Measure: Lbs.)] It is anticipated that market costs will fluctuate over the term of the contract. The Parties desire to provide for price adjustment to address such variation, computed and effected in accordance with the procedures specified herein. The CLIN unit prices agreed to by the Parties reflect the base unit prices as of the date of award. The base unit prices shall be adjusted for each Delivery Order issued during the contract period of performance. (a)Definitions. As used in this clause– Antimony Metal Market Price means the price for Antimony Regulus, Grade II (minimum 99.65% Sb) du Rotterdam as assessed and published by Argus under its Metals Market Report, expressed in U.S. dollars per pound, FOB Rotterdam, on the Date of Price Determination. Contract Price means the unit price per pound for CLIN 0001 that the Government will pay USAC for Antimony under a Delivery Order, established based on the pricing formula described in paragraph (c). Date of Price Determination means the date a quote is requested for an impending Delivery Order. Processing Factor is the charge for processing antimony, equal to %. Product Handling Fee means the charge per pound associated with sampling (*conducted by USAC of antimony feedstock, prior to processing and independent of final, third-party sampling of final product), testing/assays (*by USAC of antimony feedstock, prior to processing and independent of final, third-party testing of final product), certificate of analysis, handling, management, packaging, labeling, transportation, delivery, inspection, and acceptance, as those terms are defined in the Statement of Work. The Product Handling Fee will be $ per pound, subject to an annual increase of 2% applied on the anniversary of the Contract award date. Starting Base means the Contract Price as of the date of contract award, which will be $ per pound. The Starting Base will be the Contract Price for all Delivery Orders issued within 90 calendar days of the date of contract award. (b)Price Adjustments. The Government intends to purchase Antimony Metal Ingots from USAC under this contract over a period of five years, structured as one 60-month ordering period. The Government anticipates issuing two Delivery Orders for Antimony Metal Ingots each year. Due to uncertain market conditions, the unit price per pound of Antimony Metal Ingots shall be subject to economic price adjustments. The CLIN 0001 unit price for Delivery Orders issued in the first 90 calendar days after Contract award will be the Starting Base without any adjustment. For all orders issued more than 90 calendar days after contract award, the Contract Price shall be determined on the Date of Price Determination based on the pricing formula set forth in paragraph (c). The Government will request a quote from the Contractor before issuing each Delivery Order. The

| CONTINUATION SHEET REFERENCE NO. OF DOCUMENT BEING CONTINUED: CONTINUED ON NEXT PAGE PAGE 8 OF 37 PAGES SP8000-25-D-0007 Contractor will respond with a quote that applies the Pricing Formula as of the date of the Government’s request, which will be valid for 30 days. The Contract Price will be based on the quote, provided that the Government awards the Delivery Order within 30 days. (c)Pricing Formula. The Contract Price for each Delivery Order will be established on the Date of Price Determination, and will be equal to the Antimony Metal Market Price, multiplied by one plus the Processing Factor, plus the Product Handling Fee ($1 per pound). Once the Contract Price has been established for a Delivery Order, it will remain the same for the term of the Delivery Order and will not be subject to further adjustment. Example. When a Delivery Order is issued (on the Date of Price Determination): Pricing Formula at Date of Price Determination Pricing Calculation at 8/27/25 $ Multiplied by % Processing Fee Plus Product Handling Fee $ Contract Price (unit price per pound) $ (d)Restrictions on Orders and Adjustments. (i)Maximum and Minimum Order Quantities. As further set forth in FAR 52.216-19, the minimum order of 45,000 pounds (equivalent to one truckload) and maximum order of 2,000,000 pounds (whether for a single order or a combination of items) apply, unless the parties agree in writing in advance to a larger order. The Government is not obligated to purchase, nor is the Contractor obligated to furnish, any order for supplies and/or services less than the minimum or in excess of the maximum order quantities. (ii)Aggregate Maximum Adjustment. Notwithstanding anything in this clause to the contrary, the Contract Price for any Delivery Order hereunder shall not exceed of the Starting Base of $ per pound (that is, $ per pound). If the calculated Contract Price for any Delivery Order exceeds $ per pound, the Contract Price will be capped at $ per pound for that Delivery Order. (e)Replacement Index. If Argus ceases publication of the Antimony Metal Market Price, the Parties shall mutually agree upon a comparable published index of equivalent quality and delivery terms. (f)Order of Precedence. In the event of a conflict between this clause and any other clause of this contract pertaining to ordering or establishing unit prices for Antimony Metal Ingots, this clause shall take precedence. (End of USAC’s Proposed Ingot Pricing Terms) NO COVERED DEFENSE INFORMATION OR OTHER CONTROLLED UNCLASSIFED INFORMATION IS ANTICIPATED TO BE PROVIDED UNDER OR GENERATED IN PERFORMANCE OF THIS CONTRACT.

OF DOCUMENT BEING CONTINUED: PAGE 9 OF 37 PAGES CONTINUED ON NEXT PAGE SP8000-25-D-0007 Form SECTION C – SPECIFICATIONS/SOW/SOO/ORD Statement of Work Antimony Metal 1. BACKGROUND Antimony Metal (Sb) is a critical component of numerous Department of Defense (DoD) systems including munitions, metallurgical components, and semiconductors. It is also critical to the production of other products such as Antimony Trioxide, a flame retardant, and Antimony Trisulfide, which is used as a primer in nearly every DoD munition. This acquisition is for Antimony Metal, which can be readily transformed into the specific forms needed by DoD. Additionally, Antimony metal is a stable shelf form of antimony that can be utilized in various defense systems. Defense Logistics Agency (DLA) Strategic Materials received Congressional authority to procure antimony metal. Based on material research, the government determined to procure antimony metal ingots for addition to the National Defense Stockpile (NDS). 2. SCOPE To reduce the risk of import reliance in the antimony metal supply chain, DLA Strategic Materials intends to purchase antimony metal with estimated quantities shown in Table 1 over the course of a five-year ordering period.

(b) One or more qualification requirements apply to the supplies or services covered by this contract. For those supplies or services requiring qualification, whether the covered product or service is an end item under this contract or simply a component of an end item, the product, manufacturer, or source must have demonstrated that it meets the standards prescribed for qualification before award of this contract. The product, manufacturer, or source must be qualified at the time of award whether or not the name of the product, manufacturer, or source is actually included on a qualified products list, qualified manufacturers list, or qualified bidders list. Offerors should contact the agency activity designated below to obtain all requirements that they or their products or services, or their subcontractors or their products or services, must satisfy to become qualified and to arrange for an opportunity to demonstrate their abilities to meet the standards specified for qualification. http://quicksearch.dla.mil/qsSearch.aspx (c) If an offeror, manufacturer, source, product or service covered by a qualification requirement has already met the standards specified, the relevant information noted below should be provided.

If, after award, the Contracting Officer discovers that an applicable qualification requirement was not in fact met at the time of award, the Contracting Officer may either terminate this contract for default or allow performance to continue if adequate consideration is offered and the action is determined to be otherwise in the Government's best interests. (e) If an offeror, manufacturer, source, product or service has met the qualification requireme nt but is not yet on a qualified products list, qualified manufacturers list, or qualified bidders list, the offeror must submit evidence of qualification prior to award of this contract. Unless determined to be in the Government's interest, award of this contract shall not be delayed to permit an offeror to submit evidence of qualification. (f) Any change in location or ownership of the plant where a previously qualified product or service was manufactured or performed requires reevaluation of the qualification. Similarly, any change in location or ownership of a previously qualified manufacturer or source requires reevaluation of the qualification. The reevaluation must be accomplished before the date of award.

(b) Definitions. As used throughout this procurement note -- (1) "Index", for the purpose of price adjustment under this procurement note, means the Producer Price Index(es) reported in the monthly publication entitled, “Producer Price Indexes”, published by the United States (U.S.) Department of Labor (DOL), Bureau of Labor Statistics (BLS) for the following code number(s) and title(s): Refer to USAC’s Proposed Economic Price Adjustment Clause and USAC’s Proposed Ingot Pricing Terms. USAC’s C09 clause and pricing terms supersede and shall take precedence over this clause. (contracting officer fill-in) N/A; or the Employment Cost Index(es) reported in the quarterly publication entitled, “Employment Cost Indexes,” published by the United States (U.S.) Department of Labor (DOL), Bureau of Labor Statistics (BLS) for the following code number(s) and title(s): N/A (contracting officer fill-in) N/A. (2) "Base index" is the arithmetic average of the final version of the indexes published for the N/A months, or N/A quarters for ECI, preceding the closing date for receipt of proposals or the date required for receipt of final proposal revisions, if discussions were held. (3) "Adjusting index" means the N/A arithmetic average of the [ ] first published or [ ] final version of the index for the N/A months, or N/A quarters for ECI, prior to the month in which the adjusting contract modification is effective. (4) "Base unit price" means the unit price applicable to a quantity of a contract line item established at contract award, exclusive of any price adjustment pursuant to this procurement note. (5) “Adjustment period” means the period during which a particular adjustment to the unit price under this procurement note (calculated at the beginning of the adjustment period) will apply. The length of each adjustment period in months is the number of adjustments allowed per year in (c)(1) below divided by 12. (c) Adjustments. Prior to the end of each adjustment period, the contracting officer will calculate the adjusting index and any adjusted contract unit price(s) for the new adjustment period, and modify the contract accordingly. The contracting officer will make price adjustments in accordance with this procurement note by issuing a contract modification showing the base index, the adjusting index, the base unit price, the mathematical calculations, and the changed unit price(s). The price adjustment shall apply to orders issued after the effective date of the contract modification establishing the unit price for the adjustment period. The contracting officer will base the price adjustment(s) for each adjustment period on the percentage change between the base index and the adjusting index for the adjustment period, as applied to the base unit price (1) The contractor shall decrease its price in any particular adjustment period if the adjusting index is less than the base index. This contract allows N/A price adjustments per contract year. (2) Example of adjustment calculation: Header Header Base Index = 109.88* Adjusting index = 112.72* Less base index = 109.88 Change to index = 2.84

(d) The aggregate of the increases in any contract unit price under the terms of this procurement note shall not exceed N/A % (percent) of the original base unit price, except as provided hereafter. (1) If at any time the contractor has reason to believe that within the near future a price adjustment under the provisions of this clause will be required that will exceed the adjustment ceiling for any item, the contractor shall promptly notify the contracting officer in writing of the expected increase. The notification shall include a revised ceiling the contractor believes is sufficient to permit completion of remaining contract performance, along with appropriate explanation and documentation as required by the contracting officer. (2) If an increase in the index would raise a contract unit price for an item above the current ceiling, the contracting officer may issue a contract modification to raise the ceiling. If the contract ceiling will not be raised, the contracting officer shall so promptly notify the contractor in writing. (e) Invoices. The prices payable under this contract will be based on the latest adjusted unit price incorporated into the contract as of the date of order. (f) Retroactive adjustment. This paragraph applies only if the contracting officer selected “first published index” in paragraph (b)(3). If the Government has already paid for orders delivered during an adjustment period, the contractor may request a retroactive adjustment. The contracting officer will, base the retroactive adjustment on the difference between a higher final revised index applicable to an adjustment period and the index values used in calculating the unit price for that adjustment period, subject to the adjustment ceiling in paragraph (d) and under] the following conditions: (1) The request for equitable adjustment clearly establishes that the unit price adjustment for the adjustment period would have been higher if the final revised index had been used;, and identifies all invoices and payments to which it applies cites the specific index differences relating to the requested adjustment, and provides a calculation of the total net price adjustment for items delivered during that adjustment period. (2) The total dollar change for items delivered is $ N/A ($ unless otherwise stated) or more for the applicable adjustment period(s). (3) The contracting officer received the contractor's written request within 45 days following publication of the final revised index. The contractor shall adjust its prices downward based on the difference between a lower final revised index applicable to an adjustment period and the index values used in calculating the unit price for that adjustment period, subject to the limitation in paragraph (f)(2). (g) Revision of index. If any applicable index is discontinued or its method of derivation is altered substantially, or if the contracting officer determines that the index consistently and substantially fails to reflect market conditions, the parties shall mutually agree upon an appropriate and comparable substitute. The contracting officer will modify the contract to reflect such substitute effective on the date the index was discontinued, altered, or began to consistently and substantially fail to reflect market conditions. (h) Final invoice. The contractor shall include a statement on the final invoice confirming it has applied all decreases required by this procurement note to the amounts invoiced. (i) Disputes. The “Disputes” clause of the contract applies to any dispute arising under this procurement note. 52.216-18 ORDERING (AUG 2020) FAR As prescribed in 16.506(a), insert the following clause: (a) Any supplies and services to be furnished under this contract shall be ordered by issuance of delivery orders or task orders by the individuals or activities designated in the Schedule.

An allotment schedule is set forth in paragraph (j) of this clause. (b) For item(s) identified in paragraph (a) of this clause, the Contractor agrees to perform up to the point at which the total amount payable by the Government, including reimbursement in the event of termination of those item(s) for the Government's convenience, approximates the total amount currently allotted to the contract. The Contractor is not authorized to continue work on those item(s) beyond that point. The Government will not be obligated in any event to reimburse the Contractor in excess of the amount allotted to the contract for those item(s) regardless of anything to the contrary in the clause entitled “Termination for Convenience of the Government.” As used in this clause, the total amount payable by the Government in the event of termination of applicable contract line item(s) for convenience includes costs, profit, and estimated termination settlement costs for those item(s). (c) Notwithstanding the dates specified in the allotment schedule in paragraph (j) of this clause, the Contractor will notify the Contracting Officer in writing at least ninety days prior to the date when, in the Contractor's best judgment, the work will reach the point at which the total amount payable by the Government, including any cost for termination for convenience, will approximate 85 percent of the total amount then allotted to the contract for performance of the applicable item(s). The notification will state (1) the estimated date when that point will be reached and (2) an estimate of additional funding, if any, needed to continue performance of applicable line items up to the next scheduled date for allotment of funds identified in paragraph (j) of this clause, or to a mutually agreed upon substitute date.

The provisions of paragraphs (b) through (d) of this clause will apply in like manner to the additional allotted funds and agreed substitute date, and the contract will be modified accordingly. (e) If, solely by reason of failure of the Government to allot additional funds, by the dates indicated below, in amounts sufficient for timely performance of the contract line item(s) identified in paragraph (a) of this clause, the Contractor incurs additional costs or is delayed in the performance of the work under this contract and if additional funds are allotted, an equitable adjustment will be made in the price or prices (including appropriate target, billing, and ceiling
