Blue Star Capital (LON: BLU) says investee company SatoshiPay’s Vortex fiat-to-crypto infrastructure platform achieved volumes of $10m in January, which is more than double the previous month. In February and March total transaction volume was $7.8m because of platform outages for upgrades and a major client is changing banks. Volumes should recover. The share price climbed 24.3% to 11.5p.
Shield Therapeutics (LON: STX) says an independent peer-reviewed AdisInsight Report on ACCRUFeR®/FeRACCRU® (ferric maltol) has been published online in Pediatric Drugs, an international journal for healthcare professionals. Approval has been gained to prescribe the iron deficiency treatment to young children. The share price increased 10.8% to 8.75p.
Insig AI (LON: INSG) says 2025-26 revenues were 56% higher at £800,000 and growth is expected to accelerate. A Nasdaq listing is being considered, and this would be combined with a large share issue to invest in digital assets. Even so, Insig AI would be a very small company on Nasdaq. The share price improved 8.77% to 15.5p.
Steel structures supplier Billington (LON: BILN) has gained new contracts worth £50m even though the market is still relatively weak. This helps to underpin expectations for 2026, although some of the work will be done in 2027. The 2025 results are due to be published later this month. A pre-tax profit of £3.5m is forecast before a recovery to £8.3m. Manufacturing has been streamlined and Cavendish may reassess forecasts when the results are published. The share price gained 5.71% to 370p.
Microbiome-based ingredients developer OptiBiotix Health (LON: OPTI) increased annual revenues by 30% to £1.13m. Operating costs have been maintained at £2.6m and since then marketing costs have been reduced. Annual cost savings of up to £600,000 are being made. Increased scale should help gross margins improve. There was cash of £1.03m at the end of 2025. The share price rose 6.12% to 5.2p.
FALLERS
The bid for Deltic Energy (LON: DELT) by Rockrose Energy has lapsed. This is because UK regulatory approval of the change of control of Deltic Energy North Sea licences has still not been obtained. Deltic Energy has enough cash to last into the second half. The recommended offer was 7.46p/share. Rockrose Energy recently acquired 529,000 shares at 3.4822p each, taking the shareholding in the oil and gas company to 3.19%. The share price slumped 28.6% to 2.5p.
Mkango Resources (LON: MKA) was seeking to raise £10m at 33p/share and this was increased to £12.5m. A RetailBook offer could raise more. The cash will be invested in rare earth magnet recycling plants in UK and Germany and to buy a German magnet business. The share price declined 11.95 to 34p.
There was a return to growth at CML Microsystems (LON: CML) in the second half. However, the company will still make a full year loss, rather than the small profit previously expected, because the growth was in lower margin revenues. Supply chain problems have eased. Shore says it will publish 2026-27 forecasts after the latest results are published on 16 June. The share price fell 10.3% to 200p.
Arrow Exploration (LON: AXL) says the M-11 well in the Mateguafa Attic field, onshore Colombia has been brought onstream. It is currently producing at a restricted rate of 784bbl/d gross (392bbl/d net). The M-HZ12 well should be completed and producing in a few weeks. The current cash balance is $13m. Zeus has updated its 2026 forecast for the higher oil price and raised its free cash flow projection from $8.8m to $16.8m. The share price slipped 5.81% to 20.25p.
