Q1 2026 Corporate Update

Record Q1 Iodine Production, 44% Increase YoY

Iofina plc, specialists in the exploration and production of iodine and manufacturers of specialty chemical products, is pleased to provide an update regarding its activities during Q1 2026 (the "Period").

In the Period, Iofina Resources produced 178.9 metric tonnes ('MT') of crystalline iodine from its eight IOsorb® plants in Oklahoma, up 44% (Q1 2025: 124.1MT).

The Company experienced a record Q1 with a strong operational performance, as new capacity was added in H2 2025 and higher-than-usual brine temperatures contributed to the significant increase in iodine production. The Company now expects to exceed the previous H1 2026 production guidance of 325MT-355MT. Based on the current trends, the Company is now anticipating H1 2026 production to be closer to 385MT.

The demand for raw iodine has continued to be strong, with spot prices remaining above $70/kg, as growing market demand and supply remained consistent. The Company continues to monitor the potential impact of global supply chain issues due to recent global events, but it is pleased to report that Iofina has not been affected.

The Company confirms that it is making good progress with the development of its new, larger IOsorb® plant with Western Midstream Partners in the Permian Basin, with the plant on track to be operational in the latter part of Q3 2026.

The Company anticipates it will publish its 2025 full-year financial results to the market by early May.

President and CEO, Dr. Tom Becker, commented:

"Iofina has made a strong start to 2026, with its highest ever Q1 iodine production, resulting from its recently increased capacity, helping to drive operational strength and putting us firmly on track to deliver higher than anticipated H1 2026 production. We continue to be confident in our ability to execute our growth strategy, with our biggest plant to date on track with its construction in the Permian Basin region. Iofina's enhanced pipeline of opportunities in the Permian Basin and in Oklahoma means that we are positioning the Company into a new phase of more rapid expansion."
