Insights

Equity Compensation Counsel

Routine Form 144 notice of vested RSUs and quantities; not a market-impact filing by itself.

The filing lists a series of RSU vest events with associated share counts and vest dates. These entries document planned or proposed dispositions tied to vesting, consistent with standard compliance reporting for resales.

Because the content is a notice of intended resale rather than a completed market transaction, the immediate investor impact is limited; subsequent sale activity would be reported elsewhere.

FAQ

AI-generated questions and answers. How Rhea-AI works. Not financial advice.

What does the Form 144 filed by UBS Financial Services for CNTA indicate?

It lists proposed resale activity tied to vested RSUs. The filing enumerates multiple RSU vest dates and share counts between 09/30/2022 and 02/01/2026, serving as notice required before public resale rather than proof of completed sales.

Does the Form 144 confirm that shares were sold for CNTA?

No; Form 144 is a notice of intent to sell, not confirmation of sale. This submission lists vesting events and quantities; actual market dispositions, if any, would be reported in separate transaction filings or public trade records.

Which dates and vest events are shown in the CNTA Form 144?

The notice includes vest dates from 09/30/2022 through 02/01/2026. Specific entries include vest events on 09/30/2022, 12/31/2022, 03/31/2023, multiple 2024 dates, 02/01/2025, and 02/01/2026 with listed share counts.

Are the per-event share quantities in the filing actionable for investors?

The listed share counts show the amounts tied to each RSU vesting event. They establish the sizes of potential resale notices but do not by themselves indicate timing, sale price, or whether the shares were ultimately sold.

Who is the reporting broker-dealer listed on the Form 144 for CNTA?

The filing shows UBS Financial Services Inc. with an address at 11 Madison Ave, 4th Floor, New York, NY 10010 as the broker-dealer associated with the notice; the entry appears alongside the RSU vest listings.
