Data trap

Fortrea reports its share count only to the nearest hundred thousand: the first quarterly report gives exactly 88,800,000 on both the cover and in its tagged data, and the information statement says approximately 88.6 million. The figure recorded here is a filed rounded value, not a precise count, and any market capitalisation derived from it inherits that rounding.

The restated filings have landed; this is kept as history.

Performance since separation

Fortrea Holdings Inc. since separation-45.93%
LABCORP HOLDINGS INC. over the same window+62.23%
S&P 500 (SPY) over the same window+72.74%
Russell 2000 (IWM) over the same window+60.18%
Excess over the S&P 500-118.67%
Excess over the Russell 2000-106.11%

Measured from the first regular-way close on or after the distribution — 2023-06-30 at 34.01 — to 2026-08-21 at 18.39. Window: 3.1 years. 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.

Pre-distribution investor return

Parent, announcement to separation-4.71%
Combined (LABCORP HOLDINGS INC. + Fortrea Holdings Inc.), pre-distribution to now+71.71%
Combined excess over the S&P 500-3.07%
Combined excess over the Russell 2000+10.77%

Combined treats a pre-spin holding as 1 Fortrea share for every 1 Labcorp share valued at the parent's last close before regular post-spin trading resumed — 2023-06-29 at 206.59 — against that same basket today. That baseline is a practical proxy, not an attempt to isolate exactly how much value the separation transferred: for a large parent and a small spinco, ordinary day-to-day price noise can be bigger than the transfer itself. Run-up measures only the parent's own price, from the announcement date to that same baseline — how far the market had already moved before the separation's mechanics ever happened.

Every fact on this page comes from one of these.

Notes

Labcorp's separation of its clinical trial services business. Classified non-focus-increasing: both companies remain laboratory services businesses under the same four-digit SIC, and the separation divides diagnostics from contract research rather than industries.
