Preliminary Draft Subject to Change Executive Summary Detail of Changes Since February 5 Meeting (cont’d) Given AMID equity market capitalization decline resulting in higher market risk premium / higher weighted average cost of capital (“WACC”), Evercore adjusted its WACC methodology to utilize a size premium based on the implied equity market capitalization for each segment derived by multiplying the peer median equity market capitalization percentage of total capital to each segment’s estimated enterprise value This resulted in a lower WACC / higher resulting valuation in certain circumstances Evercore adjusted its WACC and trading multiple ranges as a result of changes in market data impacting the Discounted Cash Flow Analysis, Precedent M&A Transaction Analysis and Peer Group Trading Analysis as follows: AMID Total Partnership: increased WACC to 9.5% – 10.5% from 9.0 – 10.0% and EV / EBITDA multiple to 8.5x – 10.5x from 8.0x – 10.0x in the 2019E Peer Group Trading
