Perth robotic technology business small-cap FBR's shares are up more than 15 per cent to 3.8c in noon trading as interest from major building products maker Brickworks grows.
Brickworks has built its stake in FBR to 7.16 per cent, a month after it first took a 4.93 per cent position through a $1.9m share placement.
A notice on Thursday shows the jump is attributed to a combination of on-market purchases and off-market deals with FBR chief financial officer Aidan Flynn, chief commercial officer Kiel Chivers and general counsel Jonathan Lawe Davies, who sold 56 million shares worth $1.82m at 3.2c each.
FBR has developed Hadrian X, a mobile robotic block-laying machine and system, powered by its Dynamic Stabilisation Technology.
On July 8, FBR announced Brickworks was buying a 4.93 per cent stake through the issue of 107,201,578 shares at 1.8c per share to its subsidiary Horsley Park Holdings.
Brickworks became a substantial holder with a 5.05 per cent stake on July 19.
In May 2019, Brickworks and FBR announced a joint venture called Fastbrick to start pilot trials with Hadrian. It was discontinued in June 2020 due to the pandemic.
Shares in $3.2bn Brickworks are up 0.9 per cent to $21.11.
