Operating cash flow closely tracked net losses, with a 2026Q2 operating cash outflow of -$15.8M and a 2026Q1 outflow of -$18.4M, reflecting negligible capital expenditures below $0.3M per quarter and no dividends or buybacks, so cash burn is driven entirely by operations.

Key Metrics
Top Statement Risk
Persistent operating cash burn
Metrics are mathematically derived from official filings.
Losses Match Cash Burn Closely
As reported in financial statements, PepGen's operating cash flow tracked net losses closely, with OCF/NI ratios ranging from 0.58 to 1.25 across ten quarters and no consistent cash-based earnings cushion emerging.
Because net income is negative in every period, the OCF/NI ratio is best read as the proportion of loss that is cash-settled, and values near 1.0 indicate that non-cash charges such as stock-based compensation of $2.0M to $3.4M and D&A of roughly $1.3M did little to narrow the gap. The 2024Q2 ratio of 0.58 reflects a working capital inflow of $7.9M that masked part of the loss, a pattern that flatters a single quarter rather than the trend. The absence of any accrual cushion suggests the reported losses reflect real cash consumption rather than accounting noise, which warrants close monitoring of quarterly burn rates.
Free Cash Outflow Persists Without Revenue
Based on PEPG's reported figures, free cash flow remained negative in all ten quarters, ranging from roughly -$15.8M to -$24.2M, with no revenue base against which to measure a meaningful FCF margin.
The FCF margin cannot be computed because reported revenue is absent, so the analysis rests on absolute outflows rather than on conversion of sales into cash. Quarterly burn peaked near $24M in 2024Q3 and moderated to about $16M in 2026Q2, a trajectory that may reflect R&D reduction rather than improved operating economics. Investors should monitor whether the recent narrowing of burn proves durable, since the figures alone do not establish the duration of available funding.
Minimal Capital Intensity, Asset-Light Model
According to recent SEC filings, PepGen's reported capital expenditures were negligible, mostly below $0.3M per quarter, indicating a capital-light structure in which cash consumption is driven by operating rather than investment spending.
CapEx is effectively immaterial relative to the roughly $16M to $24M of quarterly operating outflow, so capital intensity does not explain the burn. The low maintenance requirement is consistent with a research-stage business that outsources or avoids heavy physical infrastructure. This profile suggests that the funding question turns on operating spend and external financing rather than on asset replacement needs.
No Shareholder Returns, Cash Retained
Based on reported figures, PepGen recorded no dividends or share repurchases across all ten quarters, so every dollar of available cash appears directed toward operations rather than returns to shareholders.
The absence of dividends and buybacks is unsurprising for a loss-making company, but it also means no capital return offsets the dilution risk that typically accompanies a cash-consuming biotech. Acquisition outflows are not reported in the supplied data, so no conclusion can be drawn about inorganic deployment. The implication is that the balance sheet, rather than management capital allocation choices, is the primary determinant of how long operations can be sustained.
Burn Rate Obscured by Non-Cash Add-backs
The cash flow statement may understate economic cost, since stock-based compensation of roughly $2M to $3M per quarter is added back to operating cash flow while still representing real dilution borne by existing shareholders.
Adding back SBC improves the reported operating cash picture relative to a view that treats equity compensation as an operating expense, which may make the burn look smaller than shareholders economically bear. Reported figures do not disclose off-balance-sheet commitments or financing arrangements, so the analysis cannot assess their effect, and the absence of such disclosure should not be read as their absence. The strongest bear reading is that continued losses of this scale imply ongoing reliance on external capital, though the supplied data cannot confirm the duration of current funding.
