Data trap

Two share counts a fortnight apart differ by 1.5 percent: a November 27 filing states 50,025,115 shares outstanding after the pre-distribution split, while the first quarterly report shows 49,286,517 at November 30 and attributes 49.3 million shares to the distribution. The earlier figure was an over-issuance later trued up, so publishing it overstates the company. Note also that the final Form 10 amendment carries no information statement — the definitive one is in the amendment filed the day before.

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

Performance since separation

Worthington Steel, Inc. since separation+57.34%
WORTHINGTON ENTERPRISES, INC. over the same window+24.80%
S&P 500 (SPY) over the same window+66.79%
Russell 2000 (IWM) over the same window+62.22%
Excess over the S&P 500-9.45%
Excess over the Russell 2000-4.88%

Measured from the first regular-way close on or after the distribution — 2023-12-01 at 22.20 — to 2026-08-21 at 34.93. Window: 2.7 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+66.79%
Combined (WORTHINGTON ENTERPRISES, INC. + Worthington Steel, Inc.), pre-distribution to now+107.67%
Combined excess over the S&P 500+39.90%
Combined excess over the Russell 2000+40.71%

Combined treats a pre-spin holding as 1 Worthington Steel share for every 1 Worthington Industries share valued at the parent's last close before regular post-spin trading resumed — 2023-11-30 at 44.20 — 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

Worthington Industries' separation of its steel processing business, with the parent renaming itself Worthington Enterprises while keeping the ticker WOR — unusually, a rename that does not break a price series. The distribution took effect at 12:01 a.m., before the open, so December 1 is itself the first regular-way session. Classified non-focus-increasing: both companies carry the same steel-works SIC code.
