In connection with the transactions described in the prospectus dated February 10, 2020 (the “Prospectus”), McKesson Corporation (“McKesson”) is offering, upon the terms and subject to the conditions set forth in the enclosed Prospectus, together with any amendments or supplements thereto, to exchange (the “Exchange Offer”) up to 175,995,192 shares of common stock, par value $0.001 per share (“SpinCo Common Stock”), of PF2 SpinCo, Inc., a Delaware corporation (“SpinCo”), owned by McKesson for outstanding shares of common stock, $0.01 par value (“McKesson Common Stock”), of McKesson that are validly tendered prior to the Expiration Date and not properly withdrawn. Capitalized terms used but not defined herein shall have the same meaning given to them in the Prospectus.

We are asking you to furnish copies of the enclosed materials to your clients for whom you hold shares of McKesson Common Stock, whether such shares are registered in your name or in the name of your nominee. You will be reimbursed for customary mailing and handling expenses incurred by you in forwarding any of the enclosed materials to your clients. No stock transfer taxes will generally be payable as a result of the transaction.

As described in the Prospectus, McKesson is not conducting the Exchange Offer in any jurisdiction where the offer, sale or exchange is not permitted. The Exchange Offer presented does not extend to any jurisdiction where offers to exchange or sell, or solicitations of offers to exchange or purchase, the securities offered by the Exchange Offer are unlawful, or to any person to whom it is unlawful to direct these types of activities.

No broker, dealer, commercial bank, trust company, custodian, other similar institution or fiduciary shall be deemed to be the agent of McKesson or its financial advisors, SpinCo, the exchange agent or the information agent for purposes of the Exchange Offer.

Participants in the McKesson Corporation 401(k) Retirement Savings Plan (the “McKesson 401(k) Plan”) should follow the special directions that are being sent to them by the plan administrator. Such participants may not use the Letter of Transmittal to tender shares of McKesson Common Stock held in the McKesson stock fund of the McKesson 401(k) Plan. Such participants may instruct the plan trustee to tender all, some or none of the shares of McKesson Common Stock allocable to their respective McKesson 401(k) Plan accounts, subject to certain limitations set forth in any directions provided by the plan administrator. As set forth in greater detail in these special directions, in order to allow sufficient time for the tender of shares by the trustee of the McKesson 401(k) Plan, plan participants must provide the tabulator for the trustee of the McKesson 401(k) Plan with the requisite instructions by 4:00 p.m., New York City time, on March 3, 2020.
