Whose shares does each CBRS lock-up release free?

May 14, 2026, the IPO: Sold in the IPO, the underwriters’ option included. May 14, 2026: Non-executive employees, on the first trading day May 15, 2026: Non-executive employees, on the second trading day — only if the first day's close was above 133% of the $185 IPO price ($246.05). Met: closed at $311.07 on May 14, 2026. Jun 25, 2026: Directors, officers and non-employee holders, after Q1 2026 results Aug 14, 2026: Directors, officers, employees and other holders, after Q2 2026 results Aug 19, 2026: Directors, officers, employees and other holders Sep 2, 2026: Directors, officers, employees and other holders Sep 16, 2026: Directors, officers, employees and other holders Sep 30, 2026: Directors, officers, employees and other holders Oct 14, 2026: Directors, officers, employees and other holders Oct 28, 2026: Directors, officers, employees and other holders Nov 9, 2026 at the latest: Every remaining locked share: the lock-up period ends (day 180, or two sessions after Q3 2026 results if sooner) The prospectus says “all remaining”. Its earlier releases free 78.5% of every holder’s eligible shares — 171.1M of about 218.0M by its own counts — so about 21.5%, 46.9M, are left.

Where does CBRS’s lock-up schedule come from?

From the IPO prospectus dated May 13, 2026, reviewed Oct 28, 2026. The IPO’s 34.5M shares, the underwriters’ option included, are from the first quarterly report.

What do 100% and the total mean?

100% is the 252.5M shares that can trade once every lock-up ends: the IPO’s and every release’s, which count options and restricted stock units as well as shares, so it is more than the 219.6M shares outstanding after the IPO. The total (cumulative) column is what is certain to trade by that day: the line in the chart.

Why is a release drawn as a shaded range?

A release tied to an earnings report is drawn as the range it must fall in, from the quarter’s end to the second trading day after the deadline for filing its results (45 days after the quarter, 90 after the fiscal year), and dated from the company’s 8-K once it is filed.

Will holders sell when a lock-up ends?

Not necessarily. “Up to” is what holders may sell from that day, not what they will; the underwriters can also waive a lock-up early.
