Anti-Dilution provision is a clause that gives an investor the right to maintain the same percentage ownership of a company by purchasing a proportional amount of shares in the future when securities are issued.

Dilution: What Is It?

To understand what “anti-dilution” is, you must first understand the meaning of dilution.

The term, “dilution” refers to an event in which the shareholders’ ownership of a company is reduced due to the issuance of new shares in that particular company. The ownership percentage is decreased as the whole capital is increased, the concept is simple as that.

Dilution occurs when you issue new stock in a company. Consider an investor who owns 30 out of a company's 100 shares; technically, he owns 30 percent of the company.

Imagine the corporation now issues 100 new shares to raise capital.

The investor who owned 30 percent of the company now only owns 15 percent because there is now a total of 200 shares. This situation is known as dilution. If the new shares are sold at a fair price and the value of the company rises, dilution isn't a big deal because the value of the investor's 30 shares also increases.

If new stocks are issued at a lower cost, the initial investor loses part of his control of the company and sees his stock value drop. Due to this possibility, anti-dilution provisions are often included in financial agreements to protect the equity of the investor.

Anti-Dilution: What Is It?

All venture financings have some type of anti-dilution protection for investors. With regards to a venture financing, price based anti-dilution protection refers to when the company’s shares are traded at a different price than what earlier investors have paid. This is the financial process for protecting the shares and the assets of the previous and initial investors

Anti-dilution protection, alongside the liquidation inclination, are two of the crucial elements recognizing preferred stock normally sold to investors from common stock in order to save the founders and employees and their investments.

Preferred stock can easily be converted by the choice of the holder into common stock, more often than not on a share for share premise, and is mostly changed over upon the event of a qualified first sale of stock.

Price-based anti-dilution includes expanding the quantity of shares of common stock into which every share of preferred stock is convertible.

Also, an anti-dilution modification will influence the voting privileges of the organization's stockholders on the grounds that the preferred stockholder is quite often qualified for a vote on an as changed over to common stock premise.


The absolute anti-dilution protection is asked for by investors (or officials) versus any dilution emerging as an aftereffect of the resulting offer of stock, which fundamentally ensures a specific rate responsibility for the organization for a predetermined day and age or until the event of a specific occasion, for instance, a primary sale of stock. Nevertheless, these provisions may impede the organization's capacity to raise financing.

The other sort of anti-dilution protection that preferred stock investors dependably acquire is basic anti-dilution protection. This is a change of the transformation cost of their preferred stock into common stock upon the event of any subdivisions or blends of common stock, stock profits and different appropriations, rearrangements, reclassifications or comparable occasions influencing the common stock. It means to have your stock in hand and convert them to something else and still having the same value as you had in the previous terms. This sort of anti dilution protection will help you to maintain your financial status with the company.

Anti-Dilution Provision

An anti-dilution provision is a section in an alternative, security, or merger understanding that gives the investor the privilege to keep up his or her rate responsibility for the organization by purchasing a fair number of shares of any future issue of the security. Anti-dilution provisions are some of the time described "subscription rights," "preemptive rights," or "subscription privileges." Anti-dilution provisions are especially applicable for convertible preferred stock.

There are two sorts of anti-dilution provisions: the "weighted-average” provision and the "ratchet-based" provision. The ratchet provision presents existing shareholders the privilege to purchase offers at the new lower cost. The weighted-average provision provides shareholders the privilege to buy offers at a value those records for the adjustment in the old and new offering costs.

Anti-dilution provisions shield investors from the danger of seeing new shares delivered at a lower cost than the investors already got. They likewise inspire organizations to perform well so they can issue stock at higher valuations when need be.

Why Is Anti-Dilution Important?

Anti-dilution provisions are important because they provide a safety net for investors. These provisions are included in agreements that are convertible to common stock. Preferred stockholders don't have voting rights in a company, but common stockholders do. When preferred stock converts to common stock, the stockholder has voting rights in the corporation.

In preferred stock agreements that allow the share to be converted into common stock, there is a set price where a conversion occurs. If this price was set at $1.00, the 10 shares of preferred stock would convert into 10 shares of common stock at that price. Anti-dilution provisions adjust this price if stock suddenly loses value due to shares being issued at a lower price.

This conversion allows preferred stockholders to gain common stock at a lower price than normal. The conversion means they'll have more common stock than their initial preferred stock.

Reasons to Consider Not Using Anti-Dilution

There aren't many reasons that fall into the category of anti-dilution avoidance. You will find it difficult to get investors if the corporation does not have this protection. However, there is one type of protection you should consider avoiding:

  • Full Ratchet: Full ratchet provisions make the new conversion price the same as the new stock issue price. This protection means an investor with one preferred share of $1 will end up with two common shares if stocks are later issued at .50 cents. A burden is therefore placed on common shareholders.

Reasons to Consider Using Anti-Dilution

  • Appeals to investors.

  • Protects investor equity and makes them more likely to invest more.

  • Can protect common stock value if done correctly.
