SNI was purchased by DIS. I received stock and cash. How do I calculate the cost basis of each stock?

[Tax-query1]

My stock is owned via two different brokerage firms  One firms reported all the value assigned to the sale of SNI  One firm assigned partial value to SNI with the remainder going to DIS

I really do not understand your question, I must admit.  Are you talking about the basis for the sale?  Or are you talking about the basis for the stock received?  And, where are you seeing what you're reporting?

The way this deal was structured, your "proceeds" for the sale is the sum of the cash received plus the "fair market value" of the stock received.  To calculate your gain or loss you simply subtract your basis in SNI from the "proceeds".

Your basis in the DIS stock you received is the same as the "fair market value" assigned to the stock.  Your holding period for the stock starts the day after the deal closed.  It's "as if" you received all cash for your SNI stock and then decided to take a portion of it and invest it in DIS.
