Question on Accretion/Dilution Models

I want to leverage investment banking case studies I have completed on my resume. I know that for M&A valuations such as DCF can increase the sales price in a deal by a percentage, however, what is the purpose of accretion/dilution models. I know that they are useful for analyzing the transaction but can it be used as a reason to increase an offer? Do sell side M&A pitch books contain accretion/dilution models? - Do investment bankers make accretion/dilution models for every prospective buyer?

Roughly speaking, a company's stock trades at a multiple of the company's earnings. Multiples can move for a variety of reasons, but for the sake of simplicity, assume they stay the same. If the company makes a long-term dilutive acquisition, that could mean a lower stock price. An immediately or near-term accretive deal would mean a higher stock price.

And if you're on the sellside yes you'd probably run the accretion/dilution for all the buyers to have a sense for what their ability to pay is, but it would be strange and unusual to share this with them. The math isn't that complicated and there is a 100% chance they're modeling it themselves.
