(a) The offer with respect to the Maximum Tender Offer Notes is to purchase up to $450,000,000 aggregate principal amount of the Maximum Tender Offer Notes (the “Maximum Tender Cap”). Subject to applicable law, the Offeror reserves the right, but is under no obligation, to increase, decrease or eliminate the Maximum Tender Cap at any time and in its sole discretion.

(b) Per $1,000 principal amount.

(c) The Total Consideration for Maximum Tender Offer Notes validly tendered prior to or at the Early Tender Date (as defined below) and accepted for purchase is calculated using the fixed spread and is inclusive of the Early Tender Payment.

The Any and All Tender Offers will expire at 5:00 p.m., New York City time, on September 10, 2024, unless extended or earlier terminated with respect to the applicable series of Any and All Notes (the “Any and All Expiration Date”). Holders of the Any and All Notes must validly tender and not validly withdraw their Any and All Notes prior to or at the Any and All Expiration Date to be eligible to receive the applicable Total Consideration (as defined below) for such Any and All Notes.

The Maximum Tender Offer will expire at 5:00 p.m., New York City time, on October 2, 2024, unless extended or earlier terminated (the “Maximum Tender Expiration Date”). Holders of the Maximum Tender Offer Notes must validly tender and not validly withdraw their Maximum Tender Offer Notes prior to or at 5:00 p.m., New York City time, on September 17, 2024, unless extended or earlier terminated (the “Early Tender Date”), to be eligible to receive the applicable Total Consideration for such Maximum Tender Offer Notes, which is inclusive of an amount in cash equal to the amount set forth in the second table above under the heading “Early Tender Payment” (the “Early Tender Payment”). Holders of the Maximum Tender Offer Notes who validly tender their Maximum Tender Offer Notes after the Early Tender Date but prior to or at the Maximum Tender Expiration Date will be eligible to receive the Total Consideration for such Maximum Tender Offer Notes minus the Early Tender Payment (the “Late Tender Offer Consideration”).

AnyMaximum Tender Offer Notes validly tendered in the Maximum Tender Offer and accepted for purchase will be accepted for purchase by the Offeror subject to the Maximum Tender Cap and therefore may be subject to proration (provided that all Maximum Tender Offer Notes tendered prior to or at the Early Tender Date will have priority over Maximum Tender Offer Notes tendered after the Early Tender Date). Subject to applicable law, the Offeror may increase, decrease or eliminate the Maximum Tender Cap, in any case, at any time and in its sole discretion.

The applicable consideration (the “Total Consideration”) payable for each $1,000 or €1,000 principal amount, as applicable, of the Any and All Notes validly tendered and accepted for payment pursuant to the Any and All Tender Offers will be determined in the manner described in the Offer to Purchase by reference to the applicable fixed spread for such series of Any and All Notes specified in the first table above plus the applicable yield based on (i) for the Viatris Notes, the bid-side price of the U.S. Treasury reference security and (ii) for the Mylan Notes, the bid-side price of the Bund reference security, in each case, as specified in the first table above, as quoted on the applicable Bloomberg Reference Page specified in the first table above at 10:00 a.m., New York City time, on September 10, 2024, unless extended or earlier terminated.

The Total Consideration payable for each $1,000 principal amount of the Maximum Tender Offer Notes validly tendered prior to or at the Early Tender Date and accepted for payment pursuant to the Maximum Tender Offer will be determined in the manner described in the Offer to Purchase by reference to the fixed spread specified in the second table above plus the applicable yield based on the bid-side price of the U.S. Treasury reference security specified in the second table above, as quoted on the Bloomberg Reference Page specified in the second table above at 10:00 a.m., New York City time, on September 18, 2024, unless extended or earlier terminated.

In addition to the Total Consideration, the Offerors will also pay accrued and unpaid interest on the Securities purchased up to, but not including, the applicable settlement date.  The settlement date for the Any and All Tender Offers will occur promptly after the Guaranteed Delivery Expiration Date (as defined in the Offer to Purchase) and is expected to be September 16, 2024. The settlement date for the Maximum Tender Offer Notes validly tendered and accepted for payment on the Early Tender Date will occur promptly after the Early Tender Date and is expected to be September 20, 2024. The settlement date for the Maximum Tender Offer Notes validly tendered and accepted for payment after the Early Tender Date will occur promptly after the Maximum Tender Expiration Date and is expected to be October 7, 2024.

Any and All Notes tendered pursuant to the Any and All Tender Offers may be withdrawn prior to or at, but not after, 5:00 p.m., New York City time, on September 10, 2024, and Maximum Tender Offer Notes tendered pursuant to the Maximum Tender Offer may be withdrawn prior to or at, but not after, 5:00 p.m., New York City time, on September 17, 2024 (such dates and times, as they may be extended with respect to a series of Any and All Notes or the Maximum Tender Offer Notes, the applicable “Withdrawal Deadline”).

After the applicable Withdrawal Deadline, you may not withdraw your tendered Securities unless the applicable Offeror amends the applicable Tender Offer in a manner that is materially adverse to the tendering holders, in which case withdrawal rights may be extended as such Offeror determines, to the extent required by law (as determined by such Offeror), as appropriate to allow tendering holders a reasonable opportunity to respond to such amendment. Additionally, the Offerors, as applicable and in their sole discretion, may extend a Withdrawal Deadline for any purpose. If a custodian bank, broker, dealer, commercial bank, trust company or other nominee holds your Securities, such nominee may have an earlier deadline or deadlines for receiving instructions for submissions and  withdrawals of Securities.

To the extent that less than all of the outstanding Viatris Notes and Mylan Notes are tendered and accepted for purchase in the Tender Offers, the Company and Mylan, respectively and as applicable, currently intend to (but are not obligated to) cause the applicable indenture corresponding to the Viatris Notes to be satisfied and discharged in accordance with the terms thereof and solely with respect to the Viatris Notes and redeem any remaining Mylan Notes in accordance with the terms of the applicable indenture corresponding to the Mylan Notes.

Holders of the Securities are urged to read the Offer to Purchase carefully before making any decision with respect to the Tender Offers.
