H1 2026 Corporate Update

Another Record H1 Iodine Production, 29% Increase YoY

IO#12 Remains on Track for Q3 2026

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 H1 2026 (the "Period").

During the Period, Iofina Resources produced a record 393.3 metric tonnes ("MT") of crystalline iodine from its eight IOsorb® plants in Oklahoma, up 29% on H1 2025 (305.5MT). The production also exceeded the Company's previously upgraded guidance of 385MT.

The record performance reflects strong operational execution across all production sites, with better-than-expected brine volumes at the Company's central Oklahoma plants.

Construction of the Company's largest IOsorb® plant, IO#12, in the Permian Basin, in partnership with Western Midstream Partners, is progressing well and on track. The Company anticipates commissioning the new facility during Q3 2026, with production expected to commence towards the end of September. Once operational, IO#12 is expected to contribute 170-220MT of crystalline iodine annually.

The pipeline project being undertaken by the Company's partner to deliver additional brine water to IO#11 is also advancing as planned. Iofina already has the necessary infrastructure in place to connect IO#11 once construction is complete, with the pipeline expected to be operational within Q3 2026.

Demand for crystalline iodine remains robust, with pricing during H1 2026 remaining consistent with 2025 levels. Spot iodine prices continue to trade in the mid-US$70/kg range (100% basis), and the Company expects market conditions to remain favourable through the second half of the year. Customer demand for derivative products manufactured at Iofina Chemical has also remained strong, particularly within the animal health and animal feed sectors.

The Company has clear sight of the route to achieving 2,000MT per annum of crystalline iodine production over the coming years and is negotiating with potential partners for its next IOsorb® plant. To support the expansion plans, documentation is being finalised for an additional US$10 million project loan facility with the Group's existing lender.

Looking ahead, the Company expects H2 2026 to deliver another record period of iodine production, supported by additional capacity coming online. Production will depend on the timing and ramp-up of IO#12 as well as the increase in production at IO#11, with both expected to commence during Q3 2026. The Company currently anticipates H2 2026 production in the range of 460-485MT of crystalline iodine and will update this forecast as needed.

President and CEO, Dr. Tom Becker, commented:

"It has been an outstanding first half, with another record crystalline iodine production, up 29% and beating our previously revised production upgrade. This performance reflects the continued successful execution of our growth strategy and the strong operational delivery across all our plants. At the same time, market demand for our products remains robust.

"With IO#12 on track to commence production later this quarter, adding a further 170-220MT of annual production capacity, we are entering an exciting new phase of growth. Combined with favourable iodine market fundamentals and our expanding development pipeline, we remain confident in delivering another record second half while continuing to build towards our medium-term production target of 2,000MT per annum."
