Operating cash flow was negative in every quarter, with free cash flow of -$14.4M in 2026Q2 against no capital returns, indicating the company is consuming rather than generating cash and relies on external funding to sustain operations.

Key Metrics
Top Statement Risk
Sustained cash burn dependence
Metrics are mathematically derived from official filings.
Operating Cash Burn Tracks Net Losses
As reported in financial statements, TARA's operating cash flow was negative in every quarter shown, with the OCF-to-net-income ratio ranging from 0.65 to 1.23, indicating that reported losses are largely cash losses rather than accrual-driven distortions. The 2026Q2 ratio of 0.65 stands out against the earlier quarters.
Because net losses are broadly matched by operating cash outflows, the earnings base for this company carries little accrual noise that would flatter or penalize reported results. The 2026Q2 narrowing of the ratio to 0.65 appears to reflect a working capital inflow of $6.4M rather than any improvement in underlying spending. Investors should monitor whether that inflow reverses, as it may indicate timing benefits rather than sustained cash discipline.
Free Cash Flow Deficits Persist Without Revenue
Based on reported figures, TARA's free cash flow was negative across all ten quarters, reaching -$21.3M in 2026Q1 and -$14.4M in 2026Q2, with no revenue base against which to calculate a meaningful FCF margin. The absence of revenue leaves the deficit unanchored to any commercial scale.
The FCF margin cannot be computed given zero reported revenue, so the analysis rests entirely on absolute burn rates. Quarterly deficits have ranged from roughly $7.7M to $21.3M without a clear downward trend, suggesting spending has not contracted meaningfully. This pattern implies continued reliance on external funding, though the supplied data does not describe available liquidity or financing terms.
Minimal Capital Intensity Reflects Asset-Light Model
According to recent SEC filings, TARA's capital expenditures were negligible, totaling under $350K in any quarter shown, with the largest outlay of $332K in 2026Q2 against D&A of only $72K. This pattern is consistent with an outsourced or asset-light development model.
Capex intensity is effectively zero relative to the scale of operating losses, so capital spending does not explain the cash burn. The gap between the 2026Q2 capex of $332K and depreciation of $72K may indicate a modest investment in equipment or facilities, though its scale is too small to alter the overall cash profile. The primary drivers of burn are operating costs, particularly R&D, rather than physical asset investment.
No Capital Returns, Capital Dependence Implied
As reported in financial statements, TARA paid no dividends in any quarter shown and recorded only $76K of share repurchases in 2024Q2, offset by a $76K outflow in 2024Q1, leaving no meaningful capital return activity. The company is consuming rather than distributing capital.
With negative free cash flow in every period, there is no internally generated capital available for distributions or buybacks, and the minimal repurchase activity appears immaterial. Cash deployment is effectively limited to funding operating losses. Investors should monitor future financing activity, as the supplied data does not disclose cash balances or financing arrangements that would confirm the runway.
Stock-Based Compensation Cushions Reported Burn
Based on EDBL's reported figures, TARA's stock-based compensation rose from $833K to $1.4M across the period, meaning a portion of the operating expense base is non-cash and reduces the true cash burn relative to net loss. This adjustment is material against quarterly deficits of roughly $7M to $21M.
Non-cash SBC represents roughly 6% to 10% of quarterly net losses, so the reported net loss overstates the cash cost of operations to a limited but real degree. The rising SBC trend may also signal increasing reliance on equity compensation to retain talent while cash is constrained. Investors should assess whether continued equity-based pay implies future dilution that the cash flow statement does not capture directly.
