The “Total Consideration” for each Series of Notes payable per each $1,000 principal
amount of such Series of Notes validly tendered for purchase will be based on the applicable Fixed Spread for such Series of Notes, plus the Reference Yield based on the applicable Reference Security as quoted on the applicable Bloomberg Reference
Page as of 2:00 p.m., New York City time, on August 14, 2026, unless extended by Mosaic with respect to the applicable Offer (such date and time with respect to an Offer, as the same may be extended by Mosaic with respect to such Offer, the
“Price Determination Date”). Unless extended with respect to any Offer, promptly after the Price Determination Date, Mosaic will announce in a press release, among other things, the Total Consideration applicable to each Series of
Notes accepted for purchase. In addition to the applicable Total Consideration, Holders whose Notes are accepted for purchase pursuant to an Offer will receive accrued and unpaid interest on those Notes from the last interest payment date with
respect to those Notes to, but excluding, the Settlement Date (the “Accrued Interest,” and the payment thereof, the “Accrued Coupon Payment”).
The Offers are scheduled to expire on the Expiration Date, which is 5:00 p.m., New York City time, on August 14, 2026, unless extended or earlier
terminated by Mosaic with respect to any Offer. Tenders of Notes of a Series may be validly withdrawn at any time at or prior to 5:00 p.m., New York City time, on August 14, 2026, but, except as provided in the Offer to Purchase or required by
applicable law, may not be validly withdrawn thereafter.
The “Settlement Date” will be the second business day after the Expiration
Date and is expected to be August 18, 2026.
The Offers are subject to certain conditions as described in the Offer to Purchase, including the
Financing Condition, pursuant to which Mosaic shall have completed a proposed registered public offering (the “New Notes Offering”) of new series of senior notes on terms and conditions satisfactory to Mosaic that results in its
receipt of net proceeds that are sufficient to pay the Total Consideration for all Notes validly tendered (and not validly withdrawn) and accepted for purchase by Mosaic in the Offers, plus the total Accrued Coupon Payments.
In no event will the information contained in this press release regarding the New Notes Offering constitute an offer to sell or a solicitation of an offer to
buy any New Notes. If any condition is not satisfied, Mosaic is not obligated to accept for payment, purchase or pay for, and may delay the acceptance for payment of, any tendered Notes, in each case subject to applicable law, and may terminate or
alter any or all of the Offers. The Offers are not contingent upon the tender of any aggregate minimum principal amount of Notes of any Series (subject to minimum denomination requirements as set forth in the Offer to Purchase), and none of the
Offers is conditioned on the consummation of any of the other Offers by Mosaic.
