The Company believes that its credit risk is limited because the Company’s current contracts are with companies that have a reliable payment history. The Company does </span><div style="margin-bottom:10pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">not believe that it is exposed to any significant risks related to its cash accounts, money market funds, or short-term investments.</span></div>For the nine months ended September 30, 2024 and 2023, Shenghe was the Company’s principal customer and accounted for more than 80% and 90% of revenue, respectively. Rare earth concentrate is not quoted on any major commodities market or exchange and demand for rare earth concentrate is currently constrained to a relatively limited number of refiners, a significant majority of which are based in China. Uncertainty exists as to the market price of rare earth oxide (“REO”), as evidenced by the volatility experienced in 2022 and 2023 primarily due to concerns over the global economic conditions and actual or perceived concerns over increases in the supply of or slower growth in the demand for rare earth products. Furthermore, while revenue is generated in the U.S., Shenghe conducts its primary operations in China and may transport and sell products in the Chinese market. <span id="i7a559068cc3e420795ea748b313ecd22_6747"></span>Therefore, the Company’s revenue is affected by Shenghe’s ultimate realized prices in China, including the impact of changes in the exchange rate between the Chinese yuan and the U.S. dollar. In addition, the ongoing economic conflict between China and the U.S., which has previously resulted in tariffs and trade barriers, may negatively affect the Company’s business and results of operations.
