This page shows its income statement, balance sheet, cash flow statement, and key financial ratios.

Heavy reinvestment has turned positive operating cash flow into sustained free-cash-flow deficits while leverage rises to fund expansion.
Operating cash flow stayed positive in FY2023 and FY2025, but FY2025’s$30.3M was overwhelmed by reinvestment, leaving free cash flow at-$86.2M ; accounting earnings therefore do not describe the cash available after asset investment. Debt-to-equity reached 0.5x as the current ratio fell to 1.1x, linking that investment cycle to a balance sheet that is more leveraged and less liquid than before.

Montauk Renewables Inc's current ratio of 1.11 is below the typical benchmark, resulting in a score of 24/100. However, the company holds substantial cash reserves (71% of current liabilities), which buffers actual liquidity risk. Large mature operators often run tight current ratios by design.
While Montauk Renewables Inc generated $30.3M in operating cash flow, capex of $116.5M consumed most of it, leaving -$86.2M in free cash flow. This results in a low score of 7/100, reflecting heavy capital investment rather than weak cash generation.
Montauk Renewables Inc's ROE of 0.7% shows moderate profitability relative to equity, earning a score of 40/100. This is down from 3.8% the prior year.
Montauk Renewables Inc scores 1.84, placing it in the grey zone between 1.81 and 2.99. The score is driven primarily by a large market capitalization ($355.9M) relative to total liabilities ($172.3M). This signals moderate financial risk that warrants monitoring.

For every $1 of reported earnings, Montauk Renewables Inc generates $17.35 in operating cash flow ($30.3M OCF vs $1.7M net income). This indicates profits are well-supported by actual cash generation, not accounting adjustments.
Montauk Renewables Inc earns $0.18 in operating income for every $1 of interest expense ($852K vs $4.8M). This narrow margin raises concern about the company's ability to service its debt if operating income declines.
