To estimate the trend of Moody’s adjusted leverage for ENGIE in 2022, we analyze the key components of the leverage ratio (Debt/EBITDA):

1.  **Debt Context:** ENGIE’s long-term borrowings decreased from 30.46 billion EUR to 28.08 billion EUR, but the company's overall financial profile is heavily influenced by derivative liabilities. Current and non-current derivative financial liabilities shifted significantly: Non-current derivative liabilities increased from 24.23 billion EUR (2022-01-01) to 39.42 billion EUR (2023-01-01), while current derivative liabilities decreased. Moody’s typically applies adjustments to these derivative positions.
2.  **Profitability (EBITDA proxy):** The "Current Operating Income Including Operating Mtm" dropped from 6.12 billion EUR in 2021 to 4.31 billion EUR in 2022. Additionally, the "Profit Loss From Operating Activities" experienced a sharp decline from 6.72 billion EUR in 2021 to 1.13 billion EUR in 2022. The significant increase in "Purchases And Operating Derivatives" (from 38.86 billion EUR to 74.54 billion EUR) indicates higher cost of sales/operating inputs, putting pressure on operating margins.
3.  **Cash Flow:** While "Cash Flows From Used In Operating Activities" increased (from 7.31 billion EUR to 8.59 billion EUR), the net income attributable to owners dropped drastically from 3.66 billion EUR to 0.22 billion EUR. The combination of lower operating income and the volatility/increase in adjusted debt components suggests that the leverage ratio faced upward pressure compared to the prior year.

Given the substantial decline in operating income and the complexity of the derivative liability adjustments impacting the balance sheet, the leverage profile for 2022 shows a negative trajectory compared to 2021.
