Split is new shares for old shares: in a 10-for-1 split one share becomes ten. Close before is the last close before the effective date and first close after is the first close on or after it, both as traded in CSCO's own history (not adjusted), so the two differ by about the split ratio plus that day's market move. Shares today shows how many shares one share held just before that split has become after it and every later split. Dates and ratios: EODHD.

How to read CSCO's split history
A stock split changes the number of shares and the price per share by the same factor, so the value of a holding stays the same on the day. Cisco Systems's 2-for-1 split on 23 Mar 2000 is the latest in our data: each share held before became 2 shares. Across all 9 splits since 1991, one share held just before the first split has become 288 shares.
A split does not change what a company earns or what it is worth. Per-share figures such as earnings and dividends per share are restated by the ratio, which is why old prices look different in an adjusted chart than in the newspaper of the day. The CSCO stock page has the current score and fair value range, and the CSCO price history lists daily prices with both as-traded and adjusted closes.

In a 2-for-1 split the number of shares goes up and the price per share goes down by the same factor: each share held before became 2 shares. The total value of a holding is not changed by the split itself; it only changes with the market price afterwards.
Does a stock split change what a company is worth?
No. A split cuts the same company into more (or fewer) pieces, so market value, earnings and dividends per share are all restated by the ratio. Charts and per-share figures in our data are adjusted for splits so that past and present prices can be compared.
Where does this split data come from?
Split dates and ratios come from EODHD. The closing prices around each split are the as-traded closes in our database. Feed entries that are only price-adjustment factors for spin-offs or special distributions are not counted as splits.
