Q4 2025 Corporate Update

Iofina plc, specialists in the exploration and production of iodine and manufacturers of specialty chemical products, today provides a market update regarding its activities during Q4 2025 (the "Period") and for the full year ended 31 December 2025.

In the Period, Iofina Resources produced 221.8 metric tonnes ("MT") of crystalline iodine from its eight IOsorb® plants in Central and Northwest Oklahoma (Q4 2024: 194.1 MT). Total crystalline iodine production during the second half of 2025 reached a record 437.6 MT (H2 2024: 358.0 MT), achieving the upper end of the Company's stated production guidance of 400-440 MT. Total crystalline iodine production for 2025 was a record 743.2 MT, up 17.2% from FY24 (FY24: 634.1 MT).

As a result of achieving the upper end of its production forecast along with a strong sales cycle in the second half of 2025, Iofina expects to exceed market expectations for revenue and EBITDA.1 Revenues for 2025 are projected to surpass $65m, and EBITDA for 2025 is expected to be greater than $11m. Additionally, the Company's net cash as at 31 December 2025 was $5.2m (FY24: $2.9m).

Regarding its growth projects, the Company continues to make progress on its next IOsorb® plant in the Permian Basin. The new plant is expected to process c.50,000 barrels of water, approximately twice the volume of the maximum brine throughput capacity of the existing Oklahoma IOsorb® plants, giving an annualised production target of 170-220MT. On current timelines, the operations team expects the new plant to be switched on in H2 2026.

The Company continues to advance its broader plant development pipeline and remains focused on delivering further production growth. The Company expects to produce between 325-355 MT of crystalline iodine in H1 2026 (H1 2025: 305.5MT). As previously communicated, the Company's iodine production is always second-half weighted due to the impact of winter conditions on the oil field, coupled with lower brine temperatures.

The spot iodine price was consistently above $70/kg throughout 2025, and the Company expects these market conditions to continue as we enter 2026 due to the continued robust global demand for iodine.

President and CEO, Dr. Tom Becker, commented:

"Iofina delivered another record year of production, reflecting the strength and consistency of our operations across all plants. The momentum in product sales experienced in H1 2025 continued throughout the second half of 2025. As a result, we expect full-year revenue and EBITDA to exceed current market expectations.

"Looking ahead, the Board is excited by the outlook for Iofina. We believe that the business is in a very strong position against a backdrop of increasing demand for its iodine products and our ongoing programme to continue expanding our iodine production capacity. Construction of our largest plant to date is underway in the Permian Basin, and we continue to execute our growth strategy, which we believe will result in another strong year in 2026 for Iofina. We look forward to providing further updates on the progress of the new plant and across the wider business in due course."

1For the purpose of this announcement, the Company believes market expectations for 2025 to be revenues of $62.8 million and EBITDA $10.5 million.
