What's next for CTMX, and how long its cash lasts

From CytomX Therapeutics’s SEC filings and ClinicalTrials.gov: the company’s own words, the registry’s dates, and arithmetic, not a forecast. Companies often miss their own dates.

Next step the company has named

End of 2026“A Phase 1 data update is expected by the end of 2026 with a focus on dose selection for late phase development.”Trial data · 8-K, Aug 6

What it means: the first look at a trial’s main results, as the company reports them.

Cash runway Jun 30 balance sheet

About 16 quarters

$330M in cash and short-term investments, at its spending over the last year

What it means: how long the cash would last at the same pace, before any new money.

For Pro members: the cash used each quarter, and the math.

Dilution on the horizon

  • Shelf registration (S-3ASR, filed Mar 16, 2026)

A shelf lets a company sell shares later; an at-the-market program sells them into the market over time. Neither is a sale by itself.

For Pro members: 2 raises and their amounts, and the share count against a year ago.

Insiders

CFO Christopher Ogden sold 1,624 shares on Jun 15. 4 more insider trades this year.

From their own Form 4 filings: buys and sales in the market, not awards or shares withheld for tax.

For Pro members: every trade, and Sean McCarthy’s 11 filings and quotes.

When does CTMX report earnings, and what happens after?

Expected to report Thu Nov 5, after the close (in 30 days). Not yet confirmed by the company.

The gap is the next open against the close before the report; the reaction is where that session closed. CTMX closed higher after 2 of its last 4. Past behavior, not a forecast.

Report dates and past reactions come from sessions that have already closed, so none of these figures move.

Straight Answers

Are the prices delayed?

Only on the public pages, which run at least 15 minutes behind. Pro members, and anyone on a guest pass, see real-time prices: the scanner refreshes every 15 seconds, and your watchlist every few seconds, pre-market and after hours included.

Where does the data come from?

Daily bars, quotes, reference data, headlines, and short interest come from Massive, formerly Polygon, a licensed market data vendor. The age of the quotes is shown at the top of every page. Insider trades, notable holders and profits come straight from the SEC. That means Form 4 filings, 13F filings and XBRL financial data on EDGAR. Government filings come from the public STOCK Act and Office of Government Ethics disclosures. The market-wide headlines on the market line also come from the public headline feeds CNBC, MarketWatch and Yahoo Finance publish, shown as the headline, the source and a link to the article. Splits, dividends, and the financial statements on each ticker page come from the vendor's reference data. The 8-K filings on EDGAR are read for the items that move a price. Five years of history is loaded for every stock. So the 200-day and 52-week checks rest on real history. Options flow is not part of the product.

Do I need an account?

Not to start. Tap any green button and you're in, free, with no email and no password. To keep going, create a free account with Google, Apple, or your email. There is no password to make up.

Is this investment advice?

No. It is a screening tool that scores stocks on the chart, the company's own results, and the news and filings. It does not know your situation and it is not a recommendation to buy or sell anything. Please do your own research.

The price, the score, the chart checks and readings, and the industry rank on this page are delayed at least 15 minutes. Filings are shown as filed, because a disclosure is already days or weeks old when it becomes public. Earnings dates and past reactions are settled sessions.
