A stock split divides each share into several shares with a lower par value: there are more shares outstanding, each one is worth less, and share capital does not change. A reverse split does the opposite: it groups several shares into one. They are used to bring the price per share into a range that makes trading easier.
How a stock split works, with numbers
A company has 1,000,000 shares with a par value of 10 euros: share capital of 10 million. It approves a 5×1 stock split and ends up with 5,000,000 shares of 2 euros. The capital remains 10 million, and each shareholder keeps exactly the same percentage: someone who had 100 shares now has 500, with the same total economic value. Nothing is created or destroyed; only the size of the unit changes.
A reverse split, or share consolidation, goes the opposite way: in a 1×10 reverse split, ten shares of 1 euro become one share of 10. Same capital, fewer shares, higher unit price.
Why it's done
- Make it easier for investors to enter. A high unit price leaves out small tickets and forces purchases in large blocks. Splitting the share allows smaller orders and broadens the investor base that can participate.
- Place the price in a usual range. In listed markets there is a price-per-share range in which trading is comfortable; a stock split lowers the price into it, a reverse split raises it. Consolidation is common when the price has fallen to residual levels and the share's image suffers.
- Meet admission requirements. Some markets and corporate transactions assume minimum prices or par values; adjusting the par value is the way to meet them.
What a stock split does not do is create value. The company is worth the same the day before and the day after; any effect on the price is about liquidity and perception, not fundamentals. Presenting it otherwise to investors is a mistake that costs credibility.
What it requires in a Spanish company
The par value appears in the articles of association, so a stock split or reverse split is an amendment to the articles of association: a general meeting resolution meeting the requirements of the Ley de Sociedades de Capital, a public deed, and registration with the Commercial Registry. In unlisted companies with few shareholders it is a manageable procedure; the usual reason to consider it is precisely to prepare for the entry of new investors with smaller tickets.
A reverse split adds a practical problem: fractional remainders. If you consolidate ten shares into one and a shareholder has 105, five are left over and do not complete a new share. The resolution must provide for how those fractions are resolved, normally through a sale and purchase between shareholders or through the company itself, and that detail should be settled before the vote, not after.
The tokenized angle: divisibility is decided at issuance
Here is the contrast that matters to an issuer. In a traditional share, the minimum investment unit is the par value, and changing it later costs a general meeting, a notary, and registration. In a security token, divisibility is a design parameter: when configuring the issuance you define how many decimals the security accepts and what the minimum investment is, and that decision is programmed into the instrument itself. The fractional ownership is not achieved by splitting shares after the fact, but by issuing directly in the fraction that your commercial strategy needs.
This does not eliminate company law: if you tokenize shares, the par value still exists and the bylaws still apply, as explained in the guide to tokenization of shares in Spain. The practical difference is that the issuer decides the ticket size before going out to raise capital, instead of discovering halfway through the round that its minimum unit drives away part of the demand. It is one of the design decisions that separate a tokenized issuance from a traditional capital increase, and it should be made by looking at the target investor: low minimum ticket for a broad base, high ticket for few qualified investors. The general framework is in the guide to asset tokenization for companies.
Does your minimum ticket size fit the investor you are targeting? Take the issuance diagnosis (2 min) or request a proposal.

Frequently asked questions
Does a stock split change the value of my stake?
No. A stock split multiplies the number of shares and reduces the nominal value in the same proportion, so the share capital and each shareholder's percentage remain identical. Whoever held 5 percent before the split still holds 5 percent after. It changes the size of the trading unit, not the economic value of the position.
Why do companies do reverse splits?
Almost always to raise a share price that has fallen to very low levels. A residual price makes trading difficult, distorts percentage movements and damages the perception of value. By grouping shares, for example ten into one, the unit price is multiplied without altering the share capital or each shareholder's stake.
Do security tokens need splits?
Generally not, because divisibility is defined when designing the issuance: the issuer sets the decimals and the minimum investment from the start, and the instrument is created with the desired fraction. If the token represents shares, the corporate nominal value still exists and modifying it requires the usual agreements, but the commercial investment unit no longer depends on splitting securities afterwards.
