FTSE 100 ends the week in the red. London’s blue-chip index finished lower on Friday, slipping almost 0.5%. The FTSE 100 closed at 9,667 points, dragged down by weakness across several heavyweight sectors.
Engineering group Smiths Group was the biggest faller, dropping 3.5% after agreeing to sell its security screening arm, Smiths Detection, to funds advised by CVC Capital Partners for £2bn. Metlen Energy fell 2.7%, while BP declined 2.6%, rounding out the index’s worst performers of the session.
Movers and Losers
Anglesey Mining PLC (LON: AYM) was the week’s standout performer, soaring 227% after announcing a major balance-sheet overhaul alongside a £350,000 investment from its largest shareholder and creditor, Energold Minerals.
Under the agreement, Anglesey will transfer its interests in Grängesberg Iron and Labrador Iron Mines to Energold in exchange for the elimination of roughly £4 million of debt, reducing its remaining liabilities to about £100,000.
Management said the restructuring leaves the company on a significantly stronger financial footing and allows it to concentrate fully on advancing its flagship Parys Mountain copper-zinc-lead-silver-gold project in North Wales.
GENinCode (LON: GENI) jumped 63% after announcing a wide-ranging partnership with Thermo Fisher to manufacture and distribute its CARDIO inCode-Score test across the US and EMEA. The test will launch initially as a Lab Developed Test while the company works toward full FDA approval.
Mirriad Advertising (LON: MIRI) surged around 59%, fuelled by heavy trading volumes as speculation spread that streaming platform Twitch may be using its ad-tech system. The reports remain unconfirmed but triggered strong buying interest.
Caspian Sunrise (LON: CASP) gained 44% after securing a two-year extension to the Yelemes Deep exploration licence in Kazakhstan’s BNG Contract Area. The renewal allows the reopening of Deep Well 803—where oil had previously been encountered—and strengthens the company’s position as it eyes a future 25-year production licence.
Eco (Atlantic) Oil & Gas (LON: ECO) rose 36% after announcing what it called a “transformational” deal that grants Navitas Petroleum paid-for options over key Guyana and South Africa assets, along with potential positions across Eco’s wider Atlantic portfolio. Navitas will also carry significant portions of upcoming work commitments.
Iofina (LON: IOF) climbed 5.75% to 23p after signing an agreement with Western Midstream Partners to develop its next IOsorb plant in the Permian Basin, spanning western Texas and southeastern New Mexico. The new facility will be twice the size of existing plants, able to process 50,000 barrels of brine water per day, with Western Midstream supplying the feedstock. Costing up to $9m, the plant is expected to produce up to 220 metric tonnes of iodine annually and could be operational before the end of 2026.
Losers
Deltic Energy (LON: DELT) slid 18.8% to 3.25p as uncertainty deepened around the recommended 7.46p-per-share takeover by Rockrose Energy, a Viaro Energy company. The UK regulator, the NSTA, has requested additional information before deciding on the proposed change of control for Deltic’s North Sea licences. As a result, the long-stop date for the deal has been pushed back to the end of March 2026.
Genedrive (LON: GDR) reported that full-year revenues have doubled to £1m, but cash balances have fallen sharply—from £1.2m in June 2025 to £320,000 at the end of November. The planned £1m loan facility remains under negotiation. Shares dipped 5.13% to 0.925p.
SkinBioTherapeutics (LON: SBTX) posted a 284% jump in revenue to £4.6m and cut its loss from £2.95m to £715,000. The company held £4.8m in cash at June 2025, and trading remains in line with forecasts for £6.2m revenue in 2025–26. New cosmetic products with partner Zenakine are rolling out. The shares fell sharply to 16p.
Quantum Blockchain Technologies (LON: QBT) announced three NDAs with ASIC manufacturers to allow testing of its proprietary Bitcoin-mining software on supplied hardware. A separate NDA with a major mining pool could allow QBT’s technology to be deployed without modifying miners’ operating systems. Shares eased 3.33% to 0.725p.
