Data trap

The completion filing defines an 'Effective Time' of 5:00 p.m. Central on December 2, 2022, which is the RECORD time, not the distribution — the distribution date is separately given as December 14. Skimming for a timestamp lands on the wrong one. No filing states the time of day of the distribution itself. Note also the share count is filed in thousands to one decimal, so it is precise only to the nearest hundred shares, and the parent's ticker changed from FBHS to FBIN at the open on December 15, a day after day zero.

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

Performance since separation

MasterBrand, Inc. since separation+18.31%
Fortune Brands Innovations, Inc. over the same window-15.82%
S&P 500 (SPY) over the same window+91.72%
Russell 2000 (IWM) over the same window+66.47%
Excess over the S&P 500-73.41%
Excess over the Russell 2000-48.16%

Measured from the first regular-way close on or after the distribution — 2022-12-15 at 7.70 — to 2026-08-21 at 9.11. Window: 3.7 years. The 2022-12-14 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.

Pre-distribution investor return

Parent, announcement to separation-16.85%
Combined (Fortune Brands Innovations, Inc. + MasterBrand, Inc.), pre-distribution to now-0.72%
Combined excess over the S&P 500-91.21%
Combined excess over the Russell 2000-66.10%

Combined treats a pre-spin holding as 1 MasterBrand share for every 1 Fortune Brands share valued at the parent's last close before regular post-spin trading resumed — 2022-12-13 at 54.03 — 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.

Notes

Fortune Brands' separation of its cabinets business. The parent renamed itself Fortune Brands Innovations and changed ticker the session after the distribution. Left unclassified: millwork and wood household furniture are adjacent four-digit codes inside the same broad wood-products group, and whether that counts as a change of industry is a judgement the codes do not make for us. Classified focus_increasing: the Form 10 frames MasterBrand as a scale cabinet manufacturer whose capital needs are 'specific to basic building products,' while Fortune Brands keeps a branded, innovation-driven portfolio (security, water management, outdoor living) — an explicit split in operating model and end market, not a reshuffling within one wood-products code. MasterBrand borrowed roughly $950 million and paid Fortune Brands a $940 million cash dividend at separation, cutting pro forma equity from $2.7 billion to $1.0 billion.
