limitations as analytical tools, and they should not be considered in isolation or as a substitute for the analysis of other GAAP financial measures.

These measures are not recognized in accordance with GAAP and should not be construed as a

alternative to GAAP liquidity measures. The most directly comparable GAAP measure to adjusted operating cash flow and recurring operating cash flow is net cash used in operating activities.

unable to reconcile projected adjusted EBITDA, adjusted operating expenses, recurring operating cash flow and adjusted operating cash flow to the most comparable financial measures calculated in accordance with GAAP due to rate fluctuations rates and their impact on our unrealized and realized interest rate hedging gains or losses. Sunnova offers a range for

forecasts of adjusted EBITDA, recurring operating cash flow and operating cash flow adjusted for variability in the timing of receipts and disbursements, customer usage of our assets and the impact on related reconciling items, many of which interact with each other . Therefore, the reconciliation of projected adjusted EBITDA, recurring operating cash flow and adjusted operating cash flow to projected net income (loss), total operating expenses or net cash provided by (used in) operations, as the case may be, is not available without unreasonable effort.
