Effective cash flow management is critical to the financial health and sustainability of energy companies, particularly in developing markets where economic volatility and operational challenges can constrain growth. This review explores strategic cash flow management models and their impact on driving financial growth and sustainability for energy companies operating in these markets. It highlights the importance of optimizing working capital, leveraging debt and equity financing, and implementing robust risk management frameworks to ensure liquidity and long-term viability. The review categorizes the most prevalent cash flow management models used in energy companies, such as the Free Cash Flow (FCF) model, the Discounted Cash Flow (DCF) model, and the Cash Conversion Cycle (CCC) model. Each model's relevance is analyzed in the context of fluctuating energy prices, regulatory changes, and currency instability, which are common issues in developing markets. Additionally, the role of digital tools and financial technologies (FinTech) in enhancing the precision and efficiency of cash flow forecasting and management is discussed. Key findings suggest that strategic cash flow management not only supports immediate liquidity needs but also positions energy companies for sustainable growth by optimizing investment opportunities and mitigating financial risks. A significant emphasis is placed on the need for agile financial planning, where scenario-based forecasting and adaptive cash flow strategies are essential to navigating uncertainties in the energy sector. Furthermore, the review underscores the importance of integrating environmental, social, and governance (ESG) criteria into cash flow models, aligning financial sustainability with broader corporate responsibility goals. In conclusion, this review offers a comprehensive analysis of cash flow management strategies that are crucial for energy companies in developing markets, providing actionable insights into achieving financial resilience and long-term growth.
