Recently, Joint Circular No. 00156 of the Ministry of Finance and the Ministry of Mines of the DRC / Cabinet of the Ministry of Mines / 2026 and Cabinet of the Ministry of Finance / 2026, concerning regulatory measures to standardize control over deviations in the detection of refined cobalt content in exported cobalt hydroxide under the quota system framework of the Authority for the Regulation and Control of Strategic Mineral Substances’ Markets in the DRC, is translated as follows: The English translation of the above text is:

Refined Cobalt: This week, spot refined cobalt prices generally fluctuated around 430,000 yuan/mt. During the week, prices briefly surged on news of procurement by overseas traders and export controls in the DRC, but later pulled back into the fluctuation range as macro sentiment weakened and downstream procurement follow-through proved insufficient. In terms of supply, ex-factory prices at mainstream smelters remained stable, traders' spot-futures price spread quotations were steady, and there were no significant changes in the structure of cargoes circulating in the market. In terms of demand, affected by weak cost pass-through, downstream enterprises still showed low acceptance of high-priced raw materials and only maintained a pace of just-in-time stockpiling, with no significant increase seen in actual transactions. Fundamentally, the DRC's export control policy further increased uncertainty over cobalt intermediate products exports, while the pattern of structural tightness in China's raw material supply remained unchanged, continuing to provide bottom support for cobalt prices. Cobalt Intermediate Products: This week, cobalt intermediate product prices continued to hold steady, and the market remained in a pattern of "prices quoted but no trading." In terms of supply, the impact of the DRC's export control policy continued to unfold, market concerns over whether miners could ship smoothly intensified, suppliers' bullish expectations heated up, and they continued to withhold quotations, leaving extremely scarce spot cargoes available in the market. In terms of demand, although smelters still had willingness to procure raw materials, constrained by cobalt salt prices that struggled to catch up, and with downstream orders yet to become clear, enterprises maintained a cautious wait-and-see stance, and actual transactions remained sluggish. Overall, ongoing disruptions in the DRC's export process continued to cast doubt on the timing of bulk arrivals at port, and the structurally tight raw material situation in China may further intensify. Once downstream orders are gradually finalized and procurement demand restarts, intermediate product prices are still expected to have upward momentum. Close attention should be paid to the progress of DRC exports and the pace of downstream demand recovery. Cobalt Sulphate: This week, spot cobalt sulphate prices continued to remain stable. In terms of supply, supported by tight raw materials, most smelters held firm on quotations in the range of 95,000-98,000 yuan/mt. During the week, the DRC's export control document strengthened traders' expectations for a rise in future cobalt salt prices, and low-priced shipments in the market decreased significantly. In terms of demand, most enterprises remained concerned about future orders, and with their own raw material inventory relatively sufficient, they prioritized inventory consumption and only maintained sporadic just-in-time procurement, mainly at low prices. Overall, the market remained in the inventory digestion stage in the short term, with continued bargaining between sellers and buyers, and prices were mainly driven by rangebound adjustments. However, the DRC raw material supply issue has yet to be resolved, and cost support still exists. Once downstream inventories are depleted and procurement restarts, cobalt sulphate prices are expected to regain upward momentum.

[SMM Silicone Weekly Review: The Center of Market Transactions Shifted Slightly Lower, and Downstream Wait-and-See Sentiment Increased] This week, the quotation range for mainstream quotations in China’s silicone DMC market was 13,800-14,300 yuan/mt, down 100 yuan/mt WoW. Overall market trading sentiment remained weak, with increased back-and-forth negotiations between upstream and downstream. As raw material support still persisted, midstream players remained cautious in procurement sentiment, and wait-and-see sentiment in the market was strong.

For specific related information, please refer to periodic reports. An investor asked on the investor interaction platform: Hello, Board Secretary. Recently, LME copper prices have risen sharply. Under the company’s strictly implemented hedging strategy, did this generate positive gains from closing positions during the reporting period, or was there a slight loss? Approximately how much was the amount? In addition, as the company’s revenue scale expanded, how well did net operating cash flow match net profit in 2025? Was there any cash flow strain caused by prepayments for raw material procurement? On March 19, Jintian Co., Ltd. stated on the investor interaction platform that the company’s copper processing products adopted a pricing model of “raw material prices + processing fee” and carried out hedging operations in strict accordance with the Hedging Management System to reduce the impact of raw material price fluctuations on the company’s net profit. At present, fluctuations in copper prices had a relatively small impact on the company’s operating performance. For specific related information, please refer to periodic reports. On March 18, when responding to investor questions on the interaction platform, Jintian Co., Ltd. stated that the company had continued to expand its technological leadership in high-voltage electromagnetic flat wire and had further advanced cooperation on new energy high-voltage electromagnetic flat wire projects with world-class OEMs and motor suppliers.

On March 17, Jintian Co., Ltd. said in response to investor questions on an interactive platform that the company remained committed to advancing its internationalization strategy, and construction of its newly built Thailand production site was progressing smoothly. The company's copper semis products exported outside China had an overall relatively high gross margin. In H1 2025, revenue from its principal operations outside China was up 21.86% YoY and continued to maintain a solid growth trend. The steady growth of business outside China laid a solid foundation for the company to deepen the upgrading of its global product and client mix. For specific information, please refer to the periodic reports. Jintian Co., Ltd.'s 2025 earnings forecast showed that, based on preliminary estimates by its finance department, the company expected net profit attributable to owners of the parent for 2025 to reach 700 million to 800 million yuan, representing an increase of 237.9574 million to 337.9574 million yuan from the same period last year (statutorily disclosed data), up 51.50% to 73.14% YoY. Net profit attributable to owners of the parent excluding non-recurring gains and losses for 2025 was expected to reach 440 million to 528 million yuan, representing an increase of 101.4004 million to 189.4004 million yuan from the same period last year (statutorily disclosed data), up 29.95% to 55.94% YoY. Regarding the main reasons for the expected increase in results for the period, Jintian Co., Ltd. stated: In 2025, the company implemented its "dual upgrade of products and clients" strategy, with product applications in high-end fields continuing to deepen; it stepped up expansion among clients outside China, and sales in markets outside China continued to grow; meanwhile, through digitalization initiatives, it improved operating and management efficiency, and its product gross margin level and profitability improved YoY. On January 23, Jintian Co., Ltd. said in response to investor questions on an interactive platform that Phase I of its Baotou base had been put into operation, and the annual capacity of rare earth permanent magnets had been increased to 9,000 mt. The company is currently actively advancing Phase II of the Baotou base project, with the aim of further increasing capacity to 13,000 mt. The company has a solid client base and technical reserves in the robotics field, and some rare earth permanent magnets have already been applied in the robotics sector. The company will closely monitor and follow market demand in the robotics field, further improve its product portfolio, and enhance its product competitiveness. A performance preview commentary on Jintian Co., Ltd. for 2025 released by Aijian Securities showed that the share repurchase demonstrated confidence in long-term development, while capital structure optimization was advancing steadily. The company’s high-end copper-based materials were being introduced at an accelerated pace to clients outside China in the computing power cooling sector, with sales rising rapidly and profitability improving significantly. 1) In terms of profitability, processing fees for copper busbar used in computing power are relatively high, and product mix upgrades are expected to continue lifting the company’s gross margin level; 2) In terms of shipment progress, in H1 2025, sales of the company’s copper busbar products in the cooling sector increased 72% YoY, and its high-precision profiled oxygen-free copper busbar has entered GPU cooling solutions of multiple global first-tier cooling module enterprises. The company’s copper heat pipes, liquid-cooling copper pipe & tube, and other products have also achieved bulk supply in computing servers of multiple top-tier enterprises. Copper prices fluctuations had a limited impact on the company’s profitability. 1) The company adopts a “copper prices + processing fee” pricing model, with revenue and profit primarily derived from processing fees rather than copper prices themselves. Processing fees are negotiated between the company and clients based on factors such as product specifications and process complexity, and show a certain degree of historical stickiness; 2) The company effectively hedges copper prices through hedging, while fluctuations in upstream raw material prices are mainly borne by downstream customers, resulting in a relatively small impact on the company’s profit; 3) Rapid copper prices fluctuations may affect downstream ordering willingness in phases and lengthen order cycles, but copper application scenarios are characterized by rigid demand, so the impact on total demand is limited, only changing the pace of copper product orders, and the company’s overall operating stability remains strong. The company is actively expanding into the “aluminum as an substitute for copper” direction, with material substitution optimizing the gross profit structure while enhancing its ability to hedge against copper prices fluctuations. 1) On a per-mt basis, the absolute value of processing fees for aluminum products is usually lower than that of copper-based solutions (at the same performance level, processing fees for high-precision aluminum extrusion are about 10,000 yuan/mt, versus about 20,000 yuan/mt for copper semis); however, since the per-mt price of aluminum semis is significantly lower than that of copper, usually about one-fourth of the latter, the material cost base is lower, increasing the share of processing fees in total product value. The corresponding processing fee rate of aluminum-based solutions is about 13–14 pct higher than that of copper-based solutions, providing positive support to the company’s overall gross margin; 2) In terms of supply progress, the company’s electromagnetic flat aluminum wire and aluminum 3D bent busbars for vehicles have entered the certification and mass supply stage, while inner-grooved aluminum pipe & tube for air conditioners has already begun small-batch supply. Risk Warning: Risks of lower-than-expected downstream demand for new energy or capacity release, rising copper prices, and changes in trade policies outside China.

[Price Review] During the week, silver prices remained in the doldrums. In China, the Ag (T+D) contract on the Shanghai Gold Exchange broke below the support level of 18,000 yuan/kg, while LBMA silver prices kept probing lower after falling below $75/oz. From a macro perspective, escalating geopolitical conflict in the Middle East pushed oil prices to repeated new highs, while intensifying inflation concerns significantly cooled expectations for US Fed interest rate cuts and delayed the timing of the first cut to year-end. The simultaneous strength in the US dollar index and US Treasury yields became the core factors suppressing silver prices. On Wednesday local time, the US Fed announced that it would keep interest rates unchanged. In the statement released that day, it noted that the impact of the Middle East situation on the US economy remained uncertain and that uncertainty surrounding the US economic outlook was still elevated. In addition, speculative demand and ETF holdings continued to decline, and market sentiment kept cooling. As for the gold/silver ratio, because silver posted a deeper decline, the ratio continued to rise. As of March 18, the LBMA gold/silver ratio had climbed to 63, a recent high. [Important Data] Bullish: US preliminary March one-year inflation expectations came in at 3.4%, above expectations and unchanged from the previous reading Bearish: US API crude oil inventory for the week ended March 13 increased by 6.556 million barrels, above expectations and the previous reading US EIA crude oil inventory for the week ended March 13 increased by 6.156 million barrels, above expectations and the previous reading Data and macro releases to watch next week include: Continued hawkishness from the US Fed, the ECB rate decision, US inflation/employment data, COMEX silver delivery, together with the Boao Forum and geopolitical risks On March 19, the FOMC kept rates unchanged at 3.50%–3.75%, raised its 2026 PCE forecast to 2.7%, and expectations for US Fed interest rate cuts cooled sharply. US-Iran Situation: As of March 19, the military strikes by the US and Israel against Iran had entered their 19th day, with high-intensity confrontation, no sign of a ceasefire, and the conflict spreading to multiple Gulf countries. In terms of the current impact on precious metals, financial suppression outweighed safe-haven demand. Against the backdrop of surging inflation expectations, the US dollar and US Treasury yields continued to rise, the timing of US Fed interest rate cuts was delayed, and silver prices were suppressed. [Price Forecast] Silver prices are expected to maintain a fluctuating trend in the doldrums amid the interplay between macro disruptions and fundamentals. On the macro front, caution is still warranted over the risk of continued US dollar strength and heightened volatility from any further escalation in the US-Iran conflict. On the fundamentals side, as PV export rush orders gradually approached their end, rigid demand for raw material procurement by silver nitrate enterprises declined in late March, weakening support from industrial demand. In China's spot market, as investment demand and rigid industrial demand softened, coupled with replenishment from imported silver ingots, circulating supply of silver ingots in the spot market became ample, and suppliers generally lowered spot premium quotes to facilitate transactions. The abnormally high spot premiums in China's spot market will come to an end. At the same time, profitability on imported silver ingots will also decline sharply, and spot premium quotes in actual spot silver ingot transactions are expected to return to rational levels.
