Mosaic Announces Pricing Terms of Offers to Purchase for Cash Certain of its Outstanding Debt Securities

The Mosaic Company (NYSE: MOS) ("Mosaic") today announced the Reference Yield and Total Consideration (as set forth in the table below) to be paid in connection with its previously announced cash tender offers (collectively, the "Offers") to purchase the outstanding notes described below, in each case upon the terms and subject to the conditions set forth in the Offer to Purchase dated August 10, 2026 (the "Offer to Purchase").

The Notes offered to be purchased in the Offers, in the order of acceptance priority, are the 4.050% Senior Notes due 2027 (the "2027 Notes"); 7.30% Debentures due 2028 (the "2028 Debentures"); 5.375% Senior Notes due 2028 (the "2028 Notes") and 4.350% Senior Notes due 2029 (the "2029 Notes" and together with the 2027 Notes, 2028 Debentures and 2028 Notes, the "Notes" and each a "Series of Notes") for the consideration described below, up to an aggregate purchase price, excluding the Accrued Coupon Payment (as defined below), of $1,400,000,000 (the "Tender Cap") subject to proration and the application of the Acceptance Priority Levels set forth in the table below and as further set forth in the Offer to Purchase and the terms and conditions, including, among others, a $150,000,000 cap on the aggregate consideration to be paid to purchase the 2029 Notes pursuant to the Offers (the "Series Cap") and the Acceptance Priority Procedures set forth in the Offer to Purchase.

The 2029 Notes may be subject to proration both due to the Acceptance Priority Procedures and the Series Cap such that Mosaic will only accept for purchase the 2029 Notes for aggregate consideration up to the Series Cap.

Subject to applicable law, Mosaic may, but is under no obligation to, eliminate, increase or decrease the Tender Cap and/or the Series Cap at any time prior to the "Expiration Date" of 5:00 p.m., New York City time, on August 14, 2026 (unless extended or earlier terminated by Mosaic with respect to any Offer).

In the event proration is required with respect to a Series of Notes, Mosaic will multiply the principal amount of each valid tender of such Series of Notes by the applicable proration rate and round the resulting amount down to the nearest integral multiple of the Minimum Denomination, in order to determine the principal amount of such tender that will be accepted pursuant to the applicable Offer.

The excess principal amount of Notes not accepted from the tendering Holders will be promptly returned to such Holders, and if this excess principal amount of Notes is less than $1,000, Mosaic may either accept or reject all such tendering Holders' validly tendered Notes in its sole discretion.

Additionally, Mosaic may increase the amount of Notes accepted for payment in the Offers by no more than 2% of the outstanding Notes of the applicable Series, as further described in the Acceptance Priority Procedures set forth below, without amending or extending the Offer.

The Offer to Purchase and any related documents are referred to herein collectively as the "Tender Offer Documents". Capitalized terms used but not defined in this press release have the meanings given to them in the Offer to Purchase.
