FAQ

What does Tourmaline's Form 144 for DOCN mean?

It notifies regulators of an intent to sell previously acquired shares. The Form 144 lists historical pre-IPO purchases and signals that affiliated holdings may be offered for sale, subject to applicable resale rules and any broker handling the transaction.

How many shares are referenced in the filing for DOCN?

The excerpt shows multiple lot sizes rather than a single aggregate. Examples include 724,074 shares on 01/08/2020 and 745,303 shares on 02/19/2020; the filing lists many additional dated purchases.

Who is the selling party in the Form 144 for DOCN?

The filer is Tourmaline Partners, LLC, and the transactions list an Affiliate of Issuer as the purchaser for many lots. The filing therefore reflects affiliated holdings tied to DigitalOcean Holdings, Inc.

Does Form 144 mean shares have already been sold?

No. Form 144 is a notice of proposed sale under resale rules. It reports share provenance and intent to sell; actual execution, timing, and sale proceeds are not shown in the provided excerpt.
