What is the revenue of ERC?

Might I inquire about the financial performance of ERC? I'm particularly interested in understanding its revenue streams and how they contribute to its overall profitability. Could you provide a breakdown of its major sources of income, and perhaps also offer insights into any trends or patterns in its revenue growth over time? Additionally, it would be helpful to know if there are any external factors or market conditions that significantly impact ERC's revenue generation. Thank you for your assistance in clarifying this matter.
