How to read this
Every number traces to a filing.
The tracker reads the XBRL data companies attach to their 10-Qs and 10-Ks. No estimates, no analyst models, no press releases. That also means it inherits whatever each company chose to tag.
Get this read for your company- Cash & investments
- Cash and cash equivalents plus marketable securities, current and long-term, at the latest balance-sheet date. Where a company only tags the combined total, that is used. A few small companies tag only cash.
- Burn per quarter
- Average operating cash outflow over the last four reported quarters, from the cash flow statement. Quarterly figures are derived from the year-to-date amounts in 10-Qs. This excludes financing and investing flows, so a raise or a debt draw does not flatter it.
- Runway
- Cash and investments divided by quarterly burn, times three. Self-funding means operating cash flow was positive on average. Companies plan against their own budgets, so treat this as the outside view, not their guidance.
- Net loss and R&D
- The latest three-month figures. Fourth quarters are derived from the annual number minus the nine-month year-to-date. Net loss includes non-cash items like stock compensation, which is why it usually exceeds burn.
- Raised, four quarters
- Net cash from financing activities over the last four quarters: equity raises, debt, ATM sales, less repayments and buybacks.
- Filing flags
- Going concern means the latest 10-Q or 10-K contains definite substantial-doubt language, the kind that comes from an ASC 205-40 evaluation rather than a risk-factor hypothetical. Material weakness means the filing states one was identified. Both are found by full-text search of EDGAR, so read the filing before drawing conclusions.
- Who is included
- Companies with a business address in Cambridge, Boston, Somerville, Watertown, Waltham, Lexington, Bedford, Burlington, Woburn, Newton, Needham, or Charlestown, an SEC industry code for pharmaceutical preparations, biological products, diagnostics, or commercial biological research, a listed ticker, and a periodic filing in the last fifteen months. The list is re-derived from EDGAR weekly.
- What this is not
- Not investment advice, not audited by me, and not a substitute for reading the filing. Companies restate, retag, and file late. If a number looks off, the filing wins and I would like to hear about it.
