This is why you should start the conversation with "I have drawn up a plan to save the company $14M per year. I will execute this plan in exchange for $7M upon completion."
If they say no then just go back to your regular duties.
Because blackmail is an effective salary negotiation tactic?
Very few companies would make this deal at 0.7M, 0.07M, or even 0.007M. Direct sharing a % of savings with the responsible employee is simply not the way most companies work. Consultants, now, that's different...
For a slice of 7M, just quit and come back as consultant.
Learned a lesson that you only have to "spend" (forgo) $250 to cause that company $14m in losses (that you could have prevented)
But was that your job? Because if so, you really got salary+bonus. And if you'd found nothing you'd still have got salary. So you can look at it several ways.
