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.
Get this read on your companyAbout 12 months of runway
Cash and investments of $65.1M at Q2 '26 against an average operating cash burn of $16.3M per quarter over the last four reported quarters runs out around May 2027. Under a year of runway is where ASC 205-40 going-concern evaluations, financing timing, and cost plans all get decided at once.
Cash position down $68.4M since Q3 '24
Net financing inflows of $78.6M 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.
Net loss runs $42.1M above cash burn
The Q2 '26 net loss of $67.0M includes non-cash charges, including $1.9M of stock-based compensation, that do not consume cash. Burn, not net loss, is what runway is built on.
R&D is 52% of operating expenses
$29.0M of R&D against $56.0M of total operating expenses in Q2 '26, with G&A at $25.9M. 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.
Revenue of $33.4M in Q2 '26
Collaboration and license revenue under ASC 606 and ASC 808 is the single most judgment-heavy area in biotech accounting: performance obligations, variable consideration on milestones, and the split between revenue and cost-sharing.
Going-concern language in the 10-Q filed May 13, 2026
The filing contains definite substantial-doubt language, the conclusion of an ASC 205-40 evaluation that cash may not cover twelve months from the issuance date without additional financing or cost actions. Read the liquidity note in the filing for management's plans and whether they are considered probable.
Stockholders' deficit of $330M
Liabilities exceed assets on the balance sheet. That is common with royalty financings, convertible debt, or large deferred revenue balances, and it is a fact auditors and exchange listing rules both pay attention to.
Accumulated deficit of $1.85B
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.
