A company has 500 million outstanding shares, and it issued 100 million warrants 10 years ago.

Assume that none of the warrants has been exercised yet. If tomorrow all the holders exercised their warrants, the company will have 600 million shares outstanding, and 0 warrants.

Will the company's share price be affected, since there is an increase in supply of 100 million new shares? Or would the share price have been adjusted/factored into consideration, 10 years ago when the warrants were issued?

A company typically issues warrants* to investors & institutions participating in a new share or bond issue. The warrant is a "kicker" to sweeten the deal by granting participants the right, but not the obligation, to acquire stock in the company at a set price, by a given date. (On the surface, warrants are similar to call options, but different in other respects. Perhaps another question.)

Usually, the warrants are priced out of the money, but with ample time before expiration to provide for the possibility that good company performance will raise the underlying share price above the exercise price, making the warrants worth exercising.

Since warrants tend to be issued as one part of a deal, the stock price at the time of the deal will primarily be affected by the principal financial instruments involved. The market will weigh the deal's pricing, reasons for fundraising, and likelihood for positive or negative outcomes. For instance:

  • If new shares are issued, are they at a steep discount to recent share prices? Shareholders don't like to see new shares issued at a discount, yet sometimes companies do it because they're desperate and nobody would pay a higher price. The market may drive down the share price.

  • If new shares are issued, are they at a price consistent with recent share prices? Maybe no impact. On the other hand, were the funds raised, say, to pay down high-interest debt, or fund an eagerly-anticipated expansion to fill unmet product demand? If the reason for raising money has a good probability of growing earnings, the market may react positively, else yawn.

  • If new bonds are issued, are they at an interest rate higher than expected? Shareholders seeing higher interest costs ahead, or who interpret the higher rate as lower confidence from creditors may drive the share price down. Or, if shareholders had been worried a money-losing company might be unable to raise money at all, i.e. possible bankruptcy, then the shares could have initially been distressed, and success even at the high interest rate might be interpreted as a positive sign.

  • If new bonds are issued, are they at an interest rate lower than expected? As with the share issuance case, shareholders could react positively because the funds could, say, retire existing higher-interest debt, or fuel growth.

Those aside, let's consider just the warrants:

First, at the time of the deal, yes, the warrants can impact the share price:

  • If the exercise price is set too close to the current share price, shareholders might assign a higher probability that the warrants will ultimately be exercised, resulting in dilution of earnings per share. Everything else being equal, high probability of future earnings dilution (and to what extent) is likely to have a negative impact on share price — however, you might not see any drop due to the warrants alone if the deal's primary instruments (above) gave the shares sufficient lift.

  • If the exercise price is sufficiently higher than the current share price, shareholders might assign a lower probability for exercise, i.e. less likely resulting in dilution. Everything else being equal, this is unlikely to have much of an impact on the share price — however, you might still see a change in the share price due to the deal's primary instruments (above).

Next, at the time of exercise, yes, the warrants can also impact the share price. Recognize that the warrants are being exercised because the company share price has exceeded the warrant exercise price. These are two direct consequences of the exercise:

  • The actual increase in the number of shares outstanding, and the resulting dilution of earnings, are weighed more heavily by shareholders than the mere possibility of such. Yet, it's likely this will have been realized gradually by the market as the share price approached the warrant exercise price.

  • The new shares are being issued at a discount to the current market price. If the price paid by warrant holders to acquire shares is significantly below the company's net assets per share, then shareholders may also see this reduction in net assets per share as a reason to reprice the shares in the market.

There may be other reasons yet, but I hope I convinced that the market is (a) complex, and (b) constantly reassessing what a share might be worth based on a variety of changing factors & expectations. It's simplistic to assume the impact of a warrant issue will occur all up front, or all upon exercise.

* n.b. I am referring to "warrants" in the traditional sense as used in the question, i.e. "financing warrants", typically issued by the company itself and, when exercised, resulting in issuance of new shares. Contrast with "Australian warrants" which are issued by 3rd party institutional market participants, like a pure derivative product or exchange traded option – i.e. no new shares are created. (Thanks, @Victor, for mentioning the distinction and supplying the link.)


Warrants are not issued by the company you buy shares in, they are issued by financial institutions like banks. When a warrant is issued the financial institution is actually holding the same number of underlying shares, so when an investor pays the second instalment and takes hold of the shares there are no new shares issued by the trading company. You actually acquire the underlying shares from the financial institution.

Other countries may be different, but for warrants traded in Australia refer to the following document Understanding Warrants.

    Not entirely correct. Companies do issue warrants. But they also issue them while holding the underlying stocks, so the total issue remains unchanged. seekingalpha.com/article/889291-aig-warrants-demystified

  • @littleadv Re: "they also issue them while holding the underlying stocks" -- no, that's not strictly the case. Warrant exercise frequently results in new stock being issued. Besides, unretired treasury stock being sold in lieu of newly issued shares is just as dilutive: outstanding shares, the denominator for EPS, does not include treasury stock.

    @ChrisW.Rea - that may depend on the country you are trading the warrants in. Please refer to this document Understanding Warrants for warrants traded in Australia.

    @Victor Well huh -- that's very interesting! I learned something new. You're right, it depends, & Australia certainly appears to have innovated in the area, permitting institutions to issue warrants as derivatives with a variety of features not found on standard exchange-traded options, and these resulting warrants are not what I expect when I hear the word. FWIW, from a Canadian perspective, here's what warrants are generally about. Commented Jan 20, 2014 at 15:45

    Also found this paper. Quoting page 3: "An exchange traded derivative warrant [...] in the Australian market is different in form to the common financing warrants present in other capital markets. The Australian warrant is essentially the same as a stock option [...]. Unlike financing warrants, they're not issued by the company itself, but by a 3rd party [...] and also unlike financing warrants do not involve the creation of new securities when exercised." So the kind I've been referring to are "financing warrants." Commented Jan 20, 2014 at 15:46
