The rapid development of Generative AI has brought major changes in way of functioning of different sectors throughout the world. Many research work has been done in the field of financial sector to increase the efficiency and reduce the errors due to human intervention. However, the current financial risk analysis relies on manual reviews and conventional machine learning models which repeatedly failing to process financial risk data. This study investigates how Retrieval-Augmented Generation (RAG) approach can help Large Language Models (LLM) to generate risk analysis reports for audit reports which extract detailed information from the audit reports and avoid overlooking of small details, which was a major drawback in the earlier system. This research study covers how Retrieval Augmented Generation (RAG) enhances the performance financial risk analysis of audit reports using different LLMs like GPT-4o, Gemini-1.5-flash, and LlaMa3.1. This research work includes the performance of LLMs beyond multiple metrics, including faithfulness, context precision-recall-relevancy, and answer relevance. The research findings imply that LlaMa3.1 is a great model in terms of faithfulness of the generated report with a score of 78.26%. In terms of retrieval of the documents and its context, Llama had a very strong performance by getting the score of 79.62% in context-precision, 78.26% in context-recall and 86.99% in context-relevancy. In terms of generated report, the Llama3.1 model have the score of 37.83% for answer-relevancy and Gemini-1.5-flash have a score of 58.64% for answer-correctness.
