Small-cap and AIM movers in focus:
----------
AB Dynamics PLC, down 24% at 809.0p, 12-month range 791.00p-1,500.00p. The supplier of advanced testing, simulation and measurement products sets new 12-month low on Tuesday as it cautions the "overall trading backdrop has become increasingly more challenging" during the second half of the year to August 31. AB Dynamics notes "reduced customer confidence and logistics headwinds arising from the Middle East conflict". It also reports development programmes in the automotive sector have been disrupted. It adds: "As a result, while the group's sales pipeline remains healthy, with robust levels of customer enquiries, we are seeing customers lengthen their procurement decision timelines which is adversely impacting short term order conversion and revenue generation within Testing Products & Simulation." It expects annual revenue from continuing operations between GBP90 million and GBP95 million, "lower than expected". However, it thinks margins will hold up. "The group has been actively managing operating costs and discretionary expenditure closely through the year. Consequently, the board believes it will be able to mitigate a significant degree of the adverse operational gearing impact of the lower than expected revenue, with the group's adjusted operating margin for FY26 expected to be at 20%, consistent with the group's medium term plan," AB Dynamics says.
----------
Oxford BioDynamics PLC, up 17% at 0.14p, 12-month range 0.080p-0.75p. The biotechnology firm signs its first commercial agreement for the use of 3D genomics platform EpiSwitch Orion. The agreement is part of a UK government-funded psoriatic arthritis therapy programme. "This agreement represents an important milestone for OBD and for EpiSwitch Orion. Psoriatic arthritis patients currently face a trial-and-error process in finding the most effective biologic therapy, and helping clinicians identify the right treatment for the right patient sooner is exactly the kind of unmet medical need our platform was built to address. It is also significant for us commercially: this is the first time a partner has paid for access to Orion's capabilities," Chief Executive Officer Richard Compton says.
----------
PCI-PAL PLC, up 16% at 51.0p, 12-month range 42.00p-60.00p. The secure payments provider expects revenue and adjusted earnings before interest, tax, depreciation and amortisation for the financial year ended June 30 to be above consensus. Revenue is expected to have risen 9% to GBP24.6 million from GBP22.5 million, and adjusted Ebitda is expected to have fallen to GBP1.1 million from GBP2.3 million. It puts consensus at GBP23.7 million for revenue and GBP850,000 for adjusted Ebitda.
----------
Empresaria Group, up 11% at 25.0p, 12-month range 18.00p-50.00p. Net fee income in the first half of 2026 climbs 5% on-year "despite generally challenging market conditions", the recruitment firm says. It expects adjusted pretax profit to rise almost four-fold during the half-year and now sees it amounting to GBP5.2 million for the whole of 2026, 27% above the market forecast.
----------
Essentra PLC, up 11% at 107.0p, 12-month range 78.40p-114.60p. The manufacturer and distributor of plastic-injection-moulded, vinyl-dip-moulded and metal components says half-year revenue shot up 9.0% to GBP166.1 million, with pretax profit more than doubling to GBP3.1 million from GBP1.3 million. Trading to date is in line with board expectations. It ups its half-year dividend by 13% to 0.9p per share from 0.8p.
----------
Gem Diamonds Ltd, up 6.6% at 3.635p, 12-month range 2.50p-7.44p. The Lesotho-focused diamond miner says carats recovered in the first half of the year fall 12% to 41,695, with the number sold down 4% to 42,624. However, the price per carat improves 38% to USD1,395. "Market prices for lower-quality, small, rough diamonds remain severely impacted by synthetic diamonds. This has resulted in a number of mines, with this particular size and quality diamond footprint, suspending operations," CEO Clifford Elphick says. "Letseng, with its exceptional quality and large diamond recoveries, however, has been less impacted, with encouragingly strong demand leading to an improvement in prices during H1 2026."
