The controller’s read
What the filings say.
Generated from the numbers above using the same questions I ask when I open a client’s books: how long the cash lasts, what is driving the gap between loss and burn, and where the accounting judgment sits.

Cash and investments of $492M at Q2 '26 against an average operating cash burn of $74.2M per quarter over the last four reported quarters runs out around January 2028. Between one and two years is the window where the next raise gets planned; the terms depend on what the data does before the cash does.
Cash position up $353M since Q3 '24
Net financing inflows of $495M over the last four quarters, from equity, debt, or ATM sales, more than covered operating burn. The balance is the number the board watches; the trend is the number the auditors watch.
Net loss runs $39.6M above cash burn
The Q2 '26 net loss of $110M includes non-cash charges, including $19.7M of stock-based compensation, that do not consume cash. Burn, not net loss, is what runway is built on.
R&D is 53% of operating expenses
$58.2M of R&D against $109M of total operating expenses in Q2 '26, with G&A at $50.7M. For a clinical-stage company, the accounting questions live inside that R&D line: CRO and CMC accruals, milestone recognition, and what gets capitalized versus expensed under ASC 730.
$196M of long-term debt or convertible notes
Debt in a pre-revenue biotech usually comes with liquidity covenants and, for convertibles, embedded features that need ASC 815 and ASC 470 analysis each quarter.
Accumulated deficit of $1.52B
Total losses since inception. It is also roughly the size of the net operating loss carryforward the tax provision has to track, subject to Section 382 limits after each ownership change.
