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 $118M at Q2 '26 against an average operating cash burn of $21.1M per quarter over the last four reported quarters runs out around October 2027. 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 down $83.9M since Q3 '24
Net financing inflows of $75.1M over the last four quarters, from equity, debt, or ATM sales, partly offset operating burn. The balance is the number the board watches; the trend is the number the auditors watch.
R&D is 83% of operating expenses
$18.4M of R&D against $22.3M of total operating expenses in Q2 '26, with G&A at $3.9M. 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.
Material weakness disclosed in the 10-Q filed May 12, 2026
Management identified a material weakness in internal control over financial reporting. Common causes at this stage are thin finance teams, manual close processes, and inadequate review of complex areas like revenue or equity. Remediation usually takes two or more quarters to demonstrate.
Accumulated deficit of $656M
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.
