These matters involve risks and uncertainties as discussed in the registration statement on Form <span style="white-space:nowrap">S-4</span> and <span style="white-space:nowrap">S-1</span> filed by SpinCo in connection with the Transactions (as defined below) with the U.S. Securities and Exchange Commission (the &#8220;SEC&#8221;) (File No.<span style="white-space:nowrap">&#160;333-236236)</span> and the registration statement on Form <span style="white-space:nowrap">S-4</span> filed by Change in connection with the Transactions with the SEC (File No.<span style="white-space:nowrap">&#160;333-236234),</span> as well as in McKesson&#8217;s and Change&#8217;s respective periodic reports on Form <span style="white-space:nowrap">10-K</span> and Form <span style="white-space:nowrap">10-Q</span> and current reports on Form <span style="white-space:nowrap">8-K,</span> filed from time to time with the SEC.

Without limitation, any statements preceded or followed by or that include the words &#8220;targets,&#8221; &#8220;plans,&#8221; &#8220;believes,&#8221; &#8220;expects,&#8221; &#8220;intends,&#8221; &#8220;will,&#8221; &#8220;likely,&#8221; &#8220;may,&#8221; &#8220;anticipates,&#8221; &#8220;estimates,&#8221; &#8220;projects,&#8221; &#8220;should,&#8221; &#8220;would,&#8221; &#8220;could,&#8221; &#8220;positioned,&#8221; &#8220;strategy,&#8221; &#8220;future,&#8221; or words, phrases, or terms of similar substance or the negative thereof, are forward-looking statements. These statements are based on the current expectations of the management of McKesson, SpinCo and Change (as the case may be) and are subject to uncertainty and to changes in circumstances and involve risks and uncertainties that could cause actual results to differ materially from those expressed or implied in such forward-looking statements. In addition, these statements are based on a number of assumptions that are subject to change. Such risks, uncertainties and assumptions include, but are not limited to: changes in the healthcare industry and regulatory environment; fluctuations in foreign currency exchange rates; material adverse resolution of pending legal proceedings, including those related to the distribution of controlled substances; cyberattack, natural disaster, or malfunction of sophisticated internal computer systems to perform as designed; the potential inadequacy of insurance to cover property loss or liability claims; the satisfaction of the conditions to the Transactions, and other risks related to the completion of the Transactions and actions related thereto; McKesson&#8217;s and Change&#8217;s ability to complete the Transactions on the anticipated terms and schedule; the anticipated tax treatment of the Transactions; the expansion and growth of Change&#8217;s operations; ongoing risks related to the price or trading volume of McKesson&#8217;s and Change&#8217;s common stock; failure to pay dividends to holders of McKesson&#8217;s or Change&#8217;s common stock; impairment charges for goodwill; and the risk that disruptions from the Transactions will harm McKesson&#8217;s, SpinCo&#8217;s, Change Healthcare&#8217;s or Change&#8217;s businesses. However, it is not possible to predict or identify all such factors. Consequently, while the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Forward-looking statements included herein are made as of the date hereof, and none of McKesson, SpinCo, Change Healthcare or Change undertakes any obligation to update publicly such statements to reflect subsequent events or circumstances. </p> <div></div> <p style="margin-top:1em;margin-bottom:0em"></p>

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL"><B>IRVING, TEXAS &#151; March</B><B></B><B>&nbsp;5, 2020 &#151;</B> McKesson Corporation (NYSE:MCK) today announced the final exchange ratio of 11.4086-for-one in
connection with its previously announced offer to its stockholders to exchange their shares of McKesson common stock for shares of PF2 SpinCo, Inc. (&#147;SpinCo&#148;) common stock. The exchange offer to
<FONT STYLE="white-space:nowrap">split-off</FONT> SpinCo, which holds McKesson&#146;s interest in Change Healthcare LLC (&#147;Change Healthcare&#148;), is part of McKesson&#146;s agreement with Change Healthcare Inc. (NASDAQ:CHNG)
(&#147;Change&#148;) to merge SpinCo with and into Change. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">McKesson also announced that the upper limit on the number of SpinCo shares that can be received for
each share of McKesson Common Stock tendered has been reached. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">For each share of McKesson common stock that is validly tendered and accepted for exchange McKesson
will deliver approximately 11.4086 shares of SpinCo common stock, which will be immediately converted into an equal number of shares of Change common stock upon completion of the proposed merger (subject to receipt of cash in lieu of fractional
shares). The exchange offer and merger are generally expected to be <FONT STYLE="white-space:nowrap">tax-free</FONT> to participating McKesson stockholders for U.S. federal income tax purposes except to the extent of any cash received in lieu of
fractional shares of Change common stock. The transaction is subject to customary closing conditions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">McKesson will accept 15,426,537 shares of its common stock
for exchange if the exchange offer is fully subscribed, based on the final exchange ratio. The exchange offer will be subject to proration if it is oversubscribed, and the number of shares accepted in the exchange offer may be fewer than the number
of shares tendered. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">The exchange offer is scheduled to expire at 11:59 p.m., New York City time, on March&nbsp;9, 2020, unless it is extended or terminated.
Holders of McKesson common stock may withdraw their tendered shares at any time before the expiration date of the exchange offer. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">In connection with the
transactions, Goldman Sachs&nbsp;&amp; Co. LLC is acting as financial advisor and Davis Polk&nbsp;&amp; Wardwell LLP is acting as legal advisor to McKesson. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:ARIAL">For

of Section&nbsp;27A of the United States Securities Act of 1933, as amended, and Section&nbsp;21E of the United States Securities Exchange Act of 1934, as amended. These matters involve risks and uncertainties as discussed in the registration
statement on Form <FONT STYLE="white-space:nowrap">S-4</FONT> and <FONT STYLE="white-space:nowrap">S-1</FONT> filed by SpinCo in connection with the Transactions (as defined below) with the U.S. Securities and Exchange Commission (the
&#147;SEC&#148;) (File <FONT STYLE="white-space:nowrap">No.&nbsp;333-236236)</FONT> and the registration statement on Form <FONT STYLE="white-space:nowrap">S-4</FONT> filed by Change in connection with the Transactions with the SEC (File <FONT

current reports on Form <FONT STYLE="white-space:nowrap">8-K,</FONT> filed from time to time with the SEC. The forward-looking statements contained in this release may include statements about the expected effects on McKesson, SpinCo and Change of
the separation of SpinCo from McKesson and the merger of SpinCo with and into Change (collectively, the &#147;Transactions&#148;); the anticipated benefits of the Transactions and McKesson&#146;s, SpinCo&#146;s, Change Healthcare&#146;s and
Change&#146;s anticipated financial results; and also include all other statements in this press release that are not historical facts. Without limitation, any statements preceded or followed by or that include the words &#147;targets,&#148;
&#147;plans,&#148; &#147;believes,&#148; &#147;expects,&#148; &#147;intends,&#148; &#147;will,&#148; &#147;likely,&#148; &#147;may,&#148; &#147;anticipates,&#148; &#147;estimates,&#148; &#147;projects,&#148; &#147;should,&#148; &#147;would,&#148;

the management of McKesson, SpinCo and Change (as the case may be) and are subject to uncertainty and to changes in circumstances and involve risks and uncertainties that could cause actual results to differ materially from those expressed or
implied in such forward-looking statements. In addition, these statements are based on a number of assumptions that are subject to change. Such risks, uncertainties and assumptions include, but are not limited to: changes in the healthcare industry
and regulatory environment; fluctuations in foreign currency exchange rates; material adverse resolution of pending legal proceedings, including those related to the distribution of controlled substances; cyberattack, natural disaster, or
malfunction of sophisticated internal computer systems to perform as designed; the potential inadequacy of insurance to cover property loss or liability claims; the satisfaction of the conditions to the Transactions and other risks related to the
completion of the Transactions and actions related thereto; McKesson&#146;s and Change&#146;s ability to complete the Transactions on the anticipated terms and schedule; the anticipated tax treatment of the Transactions; the expansion and growth of
Change&#146;s operations; ongoing risks related to the price or trading volume of McKesson&#146;s and Change&#146;s common stock; failure to pay dividends to holders of McKesson&#146;s or Change&#146;s common stock; impairment charges for goodwill;
and the risk that disruptions from the Transactions will harm McKesson&#146;s, SpinCo&#146;s, Change Healthcare&#146;s or Change&#146;s businesses. However, it is not possible to predict or identify all such factors. Consequently, while the list of
factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of
forward-looking statements. Forward-looking statements included herein are made as of the date hereof, and none of McKesson, SpinCo, Change Healthcare or Change undertakes any obligation to update publicly such statements to reflect subsequent
events or circumstances. </I></P>
