Spin-off
A company separating one business unit into an independent, separately listed company — existing shareholders receive shares of the new company.
In plain terms
When a company holds businesses of different character, separating one into an independent, separately listed company is a spin-off. It is like cutting a branch from a big tree and planting it separately.
Existing shareholders usually receive shares of the newly spun-off company in proportion to their holdings. So holding one stock, you can end up holding shares of two companies.
What it tells you
It is a decision to separate ill-fitting businesses so each can focus on what it does well. The value of each business, hidden when combined, gets priced separately by the market.
It is often used when a company does "selection and concentration," or tries to surface the value of a business it sees as undervalued.
Formula
no set formula — the parent separates a specific business unit into a separate entity and lists it, distributing the new company's shares to existing shareholders in proportion to their holdings.
What high or low means
When a business the market saw as "undervalued because combined" is separated, it can become an occasion for each one's value to be priced more clearly.
Conversely, the cost and complexity of separation, or the weak fitness of the spun-off company, can act as a burden.
Right after a spin-off, many sell the new company's shares without knowing "why they got them," so the price swings easily.
If the spun-off company takes on a lot of debt or depends heavily on the parent, its fitness after independence can be weak.
It is an event in the opposite direction (splitting) from M&A (combining). You have to view the intent of the split and each company's fundamentals separately.
