Data trap

This is not a clean hundred-percent distribution, and two separate things shrink the real float. Immediately before the distribution closed, N-able issued 20,623,282 new shares in a private placement and paid essentially all of the proceeds straight through to SolarWinds — so roughly 11.5 percent of the post-spin share count never reached SolarWinds shareholders and the spinco kept none of the cash. Separately, SolarWinds' private-equity sponsors held about 68.8 percent of N-able's voting power on day one, so the tradable float was a fraction of the 178.7 million shares outstanding. SolarWinds itself was taken private in 2025, so the parent's price series stops mid-window.

Still live.

Performance since separation

Measured from the first regular-way close on or after the distribution — 2021-07-20 at 12.50 — to 2026-08-21 at 3.63. Window: 5.1 years. The 2021-07-19 session was skipped: it traded on when-issued volume, not regular-way, and pricing from it would measure the return against a market that no longer existed the next day. Two benchmarks, because one is misleading: spin-offs are usually small companies, and across this period small caps lagged the S&P by several points a year on their own. Measured against the S&P alone, roughly a third of any shortfall is company size rather than the separation. Returns are arithmetic over end-of-day closing prices. Unlike every other figure on this page, they do not come from a filing.

Notes

SolarWinds' separation of its managed-service-provider software business. The final Form 10 amendment still had the ratio and both dates blank; they appear first in the definitive information statement attached to the July 12 8-K, which is a recurring pattern in this data and the reason the last amendment is never assumed to be the source. Classified non-focus-increasing: parent and spinco share a four-digit SIC and both sell IT management software.
