Gelion PLC ( (GB:GELN) ) just unveiled an update.
Gelion reported unaudited half-year results to 31 December 2025 marked by strong technical and commercial momentum in its sulfur-based battery platform. The company advanced its Nano-Encapsulated Sulfur cathode material toward commercial viability, supported by new grants, a capital raise and expanded facilities in Sydney and Europe.
Operationally, Gelion signed a full collaboration agreement with Japan’s TDK to develop large-format commercial pouch cell prototypes using its sulfur cathode material. It also secured about £0.5 million from the U.K.’s DRIVE35 programme with QinetiQ to scale and independently validate high-energy lithium-sulfur pouch cells, while successfully transferring sulfur CAM technology from the Max Planck Institute into its Advanced Commercial Prototyping Centre.
The group achieved a key technical milestone by reaching its targeted 4Q areal capacity in coin-cell testing, a benchmark seen as critical for practical high-energy-density sulfur cathodes. Post period, Gelion delivered NES cathode samples to TDK and GEN3 CAM to QinetiQ, which have already fabricated initial pouch cells that are meeting internal expectations, underscoring progress toward real-world formats.
Financially, Gelion generated £0.5 million in total income, mainly from government grants, and narrowed its adjusted EBITDA loss to £2.4 million through focused development spending. A heavily oversubscribed equity raise in November added £9.9 million in net proceeds, lifting cash to £10.5 million with no debt, providing headroom to accelerate scale-up and commercialisation activities.
The company further strengthened its technology bench by appointing leading battery scientist Professor Rachid Yazami as a technology advisor. Additional ARENA funding of £0.25 million to extend its Australian project budget reinforces institutional backing, while ongoing discussions with multiple global partners signal growing industry interest in sulfur-based cathode materials and battery recycling capabilities.
The most recent analyst rating on (GB:GELN) stock is a Hold with a £19.50 price target. To see the full list of analyst forecasts on Gelion PLC stock, see the GB:GELN Stock Forecast page.
Spark’s Take on GB:GELN Stock
According to Spark, TipRanks’ AI Analyst, GB:GELN is a Neutral.
The score is held down primarily by weak financial performance (persistent losses and cash burn) and bearish technicals (below key moving averages with negative momentum). The earnings call provides a partial offset via improved cost discipline, first revenue, a growing pipeline, and strengthened funding, but valuation remains constrained by losses and no dividend.
