He did.
The money that they frame Thaddeus with at the end of the movie is the money stolen from the safe by Jack. That safe is made by Elkhorn, the same company that made the faulty safe that caused the death of Dylan's father.
Whilst it is likely that Elkhorn would either get the money back after it is released from evidence, or claim it back on insurance, their reputation would have been irreparably tarnished.
Considering the publicity of the stunts that the Four Horsemen preformed, the theft of the money and Thaddeus's trial would have been widely known. The fact that so much money was stolen from a safe created by Elkhorn would have ensured that their name would be forever synonymous with the trial.
This means that anytime anyone wanted to purchase a safe from Elkhorn, they would remember that an incredible amount of money would have been stolen from one of their safes, and likely shop elsewhere, losing them a lot of business and possibly leading to their going bankrupt (or such was Dylan's hope). At the minimum, they would lose business and possibly have to rebrand, probably getting many executives fired in the process.
