WESTBROOK KELVIN R reported acquisition or exercise transactions in this Form 4 filing.
Mosaic Co director Kelvin R. Westbrook reported compensation-related equity activity. He received 2,437 shares of common stock upon vesting of 4,873 restricted stock units, electing to take the remaining 50% of that award in cash. Following this, he directly holds 39,807 Mosaic shares. Westbrook was also granted a new award of 7,273 restricted stock units, which will vest and be paid on the date of Mosaic’s 2027 Annual Meeting of Stockholders.
The Mosaic Company reported results from its 2026 Annual Meeting of Stockholders. Stockholders elected twelve directors, each to serve a one-year term ending at the 2027 annual meeting or until a successor is elected and qualified.
Stockholders also ratified the appointment of KPMG LLP as Mosaic’s independent registered public accounting firm for the year ending December 31, 2026. In addition, they approved, on an advisory basis, the Say-on-Pay proposal covering compensation for Mosaic’s named executive officers, as described in the proxy statement for the meeting.
The Mosaic Company reported a net loss of $258 million, or EPS of $(0.81), for Q1 2026, versus net income of $238 million a year earlier. Net sales were $3.0 billion, up from $2.6 billion, but results were hit by $323 million of pre-tax notable items.
These items were driven largely by $442 million of charges tied to idling the Araxa and Patrocinio operations in Brazil; $328 million of this was non-cash. Adjusted EBITDA was $416 million and adjusted EPS was $0.05.
Potash performed relatively well with net sales of $667 million, operating earnings of $177 million and adjusted EBITDA of $275 million, helped by higher prices. Phosphate and Mosaic Fertilizantes posted operating losses of $48 million and $422 million, pressured by sharply higher sulfur and ammonia costs and Brazil-related charges.
Cash flow from operations was $104 million, while free cash flow was $(253) million after $357 million of capital spending. For 2026, Mosaic now guides to about 9 million tonnes of potash production, capital expenditures of $1.25 billion and a high‑20s to low‑30s percent adjusted effective tax rate. Phosphate production guidance has been withdrawn amid record sulfur prices and the company is implementing partial curtailments in the U.S. and Brazil.
FMR LLC files Amendment No. 3 to a Schedule 13G/A reporting beneficial ownership of 9.1% (29,043,388.08 shares) of Mosaic Co common stock. The filing lists sole voting power of 21,181,959.88 shares and sole dispositive power of 29,043,388.08 shares. The document is signed under a power of attorney and references an exhibit for subsidiary identification.
Mosaic Co/The reports a Schedule 13G showing Vanguard Capital Management beneficially owned 23,414,047 shares of Common Stock, representing 7.37% of the class as of 03/31/2026. The filing lists sole voting power for 2,778,708 shares and sole dispositive power for 23,414,047 shares. The report is signed by Ashley Grim on 04/30/2026.
The Mosaic Company is holding its 2026 Annual Meeting of Stockholders as a virtual-only event on May 28, 2026 at 12:00 p.m. Eastern Time. Stockholders of record on April 2, 2026 can vote online, by phone or by mail on three main items: electing 12 directors to one‑year terms, ratifying KPMG LLP as independent auditor for 2026, and approving an advisory say‑on‑pay vote for Named Executive Officers. The proxy also highlights 2025 results, including net sales of $12,052.4 million, net earnings of $540.7 million and diluted EPS of $1.70, and describes Mosaic’s largely performance‑based executive pay, strong prior say‑on‑pay support and extensive corporate governance and sustainability practices.
The Mosaic Company is idling and demobilizing its Araxá Mining and Chemical Complex and related mining activities at the Patrocínio Complex in Brazil as part of efforts to reduce costs and redeploy capital. These steps will lead to workforce reductions and a planned sale process for Araxá assets, while Mosaic continues developing a niobium opportunity at Patrocínio.
The company expects the idling to cut annual phosphate production at Mosaic Fertilizantes by about 1 million tonnes and to record a pre-tax book impact of $350 to $400 million in the first quarter of 2026, including $275 to $300 million of impairments on assets held for sale and other write-offs. Following a potential transaction, Mosaic expects annual capital expenditures to decline by approximately $20 to $30 million and operating expenses by about $70 to $80 million, and it describes the impact on adjusted EBITDA as limited, excluding one-time closure costs.
The Vanguard Group amended its Schedule 13G/A to report zero beneficial ownership of Mosaic Co/The common stock. The filing states that following an internal realignment effective January 12, 2026, certain Vanguard subsidiaries now report holdings separately and Vanguard no longer is deemed to beneficially own those securities.
The amendment is signed by Ashley Grim as Head of Global Fund Administration on March 27, 2026. The filing lists 0 shares and 0% ownership, with voting and dispositive powers reported as 0.
