Small-cap and AIM movers in focus:

The medical imaging technology company enters an annual subscription agreement with a leading health system for its quantitative neuro-oncology imaging software. "The healthcare organisation is among the first in the region to provide access to IB's advanced quantitative MRI technologies, bringing objective, standardised imaging biomarkers to neuro-oncology care and supporting more informed clinical decision-making throughout the patient journey," it says.

----------

Tertiary Minerals PLC, up 15% at 0.075p, 12-month range 0.035p-0.14p. It achieves the best silver-copper intersection to date at the Discovery Zone at Mushima North in Zambia. "All thirteen holes intersected near surface, silver-copper-zinc mineralisation, with several holes ending in mineralisation and thus extending the mineralisation at depth, including the best silver-copper intersection to date on the project," it says.

----------

Mpac Group PLC, down 6.3% at 325.50p, 12-month range 200.00p-405.00p. Its pretax loss in the first half of 2026 narrowed to GBP500,000 from GBP8.8 million, though revenue fell 2.3% to GBP71.0 million from GBP72.7 million. "The pipeline of potential future projects continues to grow, and is now larger and building faster than last year. However, global customer decision making remains slow, and the impact of 50% US tariffs recently imposed on goods from Canada is not yet clear. The timing of a broader market recovery remains uncertain," the packaging firm cautions.

----------

everplay group PLC, up 2.8% at 384.50p, 12-month range 205.00p-415.00p. The publisher of premium video games reports a "resilient" first half and looks ahead to "major title launches" in the second. Pretax profit in the first half of 2025 falls 89% to GBP1.6 million from GBP14.3 million, as revenue 8% falls to GBP66.9 million from GBP72.4 million. It reports a "strong start" to the second half.
