AIM weekly movers this week were led by contrasting fortunes at PCI-Pal (LON: PCIP) and AB Dynamics (LON: ABDP), with a payments software beat and an automotive testing profit warning pulling the index in opposite directions.
AIM Weekly Movers: Risers
Sunda Energy (LON: SNDA) chief executive Dr Andy Butler has agreed to acquire from Alumni Capital the outstanding convertible loan notes with a face value of £400,000. He says he does not currently intend to convert the notes. The share price rebounded 44.2% to 1.55p.
Cyber security software and services provider Shearwater Group (LON: SWG) said a strong close to the year to June 2026 left trading ahead of expectations. Revenues have been upgraded 18% to £42m and earnings per share raised from 4.5p to 4.9p. Net cash of £5.6m at the end of June 2026 represents around 50% of market capitalisation, and the board is considering share buybacks or dividends. Cavendish is not changing its 2026-27 forecast at this point. The share price jumped 36.3% to 62p.
Cloud-based secure payments technology developer PCI-Pal reported revenues up 14% to £24.6m for 2025-26, coming in below a prior consensus of approximately £25.5m flagged by the London Stock Exchange in July 2025, though the company characterised the outcome as better than expected. The expected loss for the year narrowed to £800,000.
Annualised recurring revenues rose 29% to £24.4m, providing the base for a 2026-27 revenue forecast of £27m that will be revisited when full-year figures are published. In the prior financial year, PCI-Pal’s FY25 results showed ARR growing 25% to £19.3m, the largest absolute ARR increase the group had delivered to that point, and a gross retention rate above 95%.
The group now services over 700 customers across Europe, North America, and ANZ. On the contract front, PCI-Pal secured an eight-year HMRC renewal announced on 2 July 2026, and a new strategic partnership with NiCE Systems Inc as a reseller was disclosed on 30 July 2026. PCI-Pal’s half-year results for the six months ended 31 December 2025 showed recurring revenue at 93% of total group income.
Chief executive James Barham bought 26,466 shares at 56.5p each following the update. The share price gained 28.7% to 56p.
Xcalibur Multiphysics Group has acquired a 25.5% stake in subsurface resources data supplier Getech Group (LON: GTC), buying out Octopus (16.4%) and First Equity (6.42%). Xcalibur is a global specialist in airborne and mapping geophysics. The Getech share price recovered 23.4% to 2.9p.
AIM Weekly Movers: Fallers
Supercapacitors developer Cap-XX (LON: CPX) raised £2.2m via a placing and subscription at 0.15p per share to fund manufacturing line upgrades. A retail offer closing on 3 August could raise additional funds. The share price fell 44.2% to 0.145p.
Shield Therapeutics (LON: STX) reported group revenues of $30.4m for the six months ended 30 June 2026, a rise of 42% year-on-year according to the company’s interim results filed on Investegate (the original snippet stated 41%). The growth was partly driven by a $7.9m milestone payment from China. US volumes of the ACCRUFeR iron replacement treatment increased, but lower US selling prices meant revenues from that market fell.
Operating profitability was maintained, though not at a level sufficient to cover interest charges. Cash stood at $8.3m at the end of June 2026, against outstanding debt. In the full year 2025, audited results showed US ACCRUFeR net sales of $45.8m at an average net price of $223. Shield Therapeutics has previously stated a peak US revenue potential of $450m for ACCRUFeR. The share price declined 35.8% to 3.95p.
AB Dynamics (LON: ABDP) said trading has become more challenging due to reduced customer confidence and logistics problems relating to the Middle East. Decision timelines are lengthening, hitting near-term orders. Full-year revenues are now expected in the range £90m to £95m, against a prior consensus of £116.7m, though that consensus figure includes the Chinese on-road testing business VadoTech that AB Dynamics is exiting.
In the prior year ended 31 August 2025, AB Dynamics reported total revenue of £114.7m, with Morningstar/Alliance News reporting that continuing operations contributed £104.2m of that figure. The snippet estimates VadoTech revenues at £4m; Proactive Investors reports that VadoTech’s contract will be terminated in the first half of the FY2027 financial year and the unit treated as a discontinued operation. European carmakers, particularly affected by restructuring, have contributed to the weakened customer confidence AB Dynamics cited. Cost reductions are expected to keep adjusted operating margin at around 20%. The share price fell 30.2% to 740p.
Gunsynd (LON: GUN) has relinquished its interests in the Bear Twit and Hornby Bay projects and is in talks with Pinwheel Resources to terminate the agreements. The company spent £110,000 on the projects and had committed to a further £100,000 per year for two years. Management said it wants to concentrate cash on the barb gold project in Manitoba. The share price dipped 22.7% to 0.085p.
AB Dynamics’ guidance update leaves a wide gap between the low end of its new range and last year’s continuing-operations revenue: the market will watch for whether contract delays shorten or extend as European automotive restructuring runs its course.
