How do warrants differ from options, and what impact does exercise price have on dilution?

Warrants and exchange-traded options are both derivative instruments giving the holder the right to buy shares at a specified price, but they differ in critical ways.

Key Differences:

Exercise Price and Dilution:

When a warrant holder exercises, the company issues new shares and receives cash equal to the exercise price. The dilution impact depends on the relationship between the exercise price and the current share price.

Example:

Oakhaven Corp has 2 million shares outstanding at $60 each (equity value = $120M). It has 200,000 warrants outstanding with a $40 exercise price.

If all warrants are exercised:

• Cash received: 200,000 x $40 = $8,000,000
• New equity value: $120M + $8M = $128,000,000
• New shares outstanding: 2,000,000 + 200,000 = 2,200,000
• Diluted share price: $128M / 2.2M = $58.18

The existing shareholders lose $60.00 - $58.18 = $1.82 per share in value, while warrant holders gain $58.18 - $40.00 = $18.18 per warrant.

The lower the exercise price relative to market price, the greater the dilution because the company receives less cash per new share created. At-the-money warrants cause minimal dilution, while deep-in-the-money warrants cause maximum dilution.

Treasury Stock Method (for EPS):

For diluted EPS calculations, assume warrant proceeds buy back shares at market price. Only the incremental shares (those not "covered" by the buyback) are added to the denominator.
