Pre-split price is the final regular-session close on a trading day strictly before the split calendar date. Post-split price is the first session open on or after that date. Both values come from unadjusted end-of-day bars for the company's primary listing.
The Type column reflects the data feed's event category (for example stock split vs stock dividend). When the feed labels a generic split but the ratio is reverse (e.g. 1:10), we show reverse stock split. Optional editorial context for a row appears next to the split ratio as an info icon (hover or keyboard focus on desktop; tap on mobile). The same text is listed under Row notes when that block is expanded.
