A spin-off is when a company takes one of its businesses and turns it into a separate, independent company. In the SEC's Investor.gov definition, the parent company hands out shares of the new company to its own shareholders, usually pro rata, meaning in proportion to what they already own. So someone who owns the parent's stock would typically end up holding shares of two companies instead of one. Unlike an IPO, where shares are sold to investors for cash, the parent in a spin-off usually receives no cash for the shares it hands out.
Here's a real example in the news. On Tuesday, November 3, the Financial Times and then the Wall Street Journal reported that CVS Health plans to split its roughly $117 billion business in two. According to the Journal, one company would keep the CVS Health name and hold the Aetna insurance unit and the Caremark pharmacy benefits business, while a second company, CVS Pharmacy, would hold about 9,000 retail drugstores, the mail-order pharmacy and MinuteClinic. The Journal said the split is expected in the first half of 2028, and the FT cautioned that the structure and timing could still change. CVS is scheduled to report quarterly results on Wednesday, November 4, when more details may come out.
A planned spin-off is still just a plan until the company publishes the official details. Things like how many new shares you'd get for each share you own, and on what date, aren't set yet. Those details show up in company announcements and SEC filings, which anyone can search for free on the SEC's EDGAR database. Ever wondered how spin-off shares show up in a brokerage account, or what "pro rata" really means? Ask below, there are no silly questions here.

Spin-offs are a good reminder that a plan is still just a plan until the company files the official details, so try to wait for the filing before you act on the headline. Writing down what you'd check on EDGAR first is a simple habit that keeps you calm.
