CapAI reports "multiple products" are moving to user availability from the development stage. "The CapAI board believes that the transition of multiple platforms into live availability, combined with a growing pipeline of opportunities under evaluation, positions capAI for its next phase of growth. The company remains focused on disciplined execution, capital efficiency and the selective advancement of high-potential initiatives," it adds.

----------

Crest Nicholson Holdings Ltd, down 39% at 65.7p, 12-month range 59.70p-198.50p. The housebuilder lowers sales and profit expectations for the current financial year and warned of higher debt than forecast. The firm says it is acting "quickly and decisively" to prioritise cash and balance sheet strength whilst the uncertainty caused by the Middle East crisis persists. It reports a reduction in new enquiries and visitor levels since its last update in March, a "marked" softening in sentiment among prospective land purchasers and that buyers have become more cautious.

----------

Mpac Group PLC, down 12% at 228.00p, 12-month range 222.60p-495.00p. The packaging firm reports a swing to a 2025 pretax loss of GBP7.7 million, from profit of GBP3.4 million. In addition, Chief Financial Officer Will Wilkins is to leave the position in July, to join Ibstock. Duncan Tyler, corporate development director, is to take on the role of interim CFO.

----------

Nichols PLC, up 4.1% at 966.04 pence, 12-month range 880.00p-1,480.00p. The soft drinks company says revenue in the three months to March 31 climbed 4.3% on-year to GBP41.0 million. It is "an encouraging start to the year in-line with the board's expectations," the firm says ahead of its annual general meeting on Tuesday.

----------

Mears Group PLC, up 2.0% at 386.00 pence, 12-month range 310.00p-421.37p. The provider of housing and social care wins a new long-term contract with Moat Homes valued at over GBP200 million over an initial 10-years. "The contract will see Mears deliver responsive and void maintenance and planned works to around 20,000 homes across the South‑East of England and includes an option to extend for a further five years," Mears adds.
