OFX Group (ASX:OFX)

OFX Group shares surged after the company announced it had entered into a transaction process deed for an all-cash acquisition of 100% of its issued share capital by Alakazam Holdings Bidco, the direct owner of UK-based international payments company Equals Group. The move follows a strategic review initiated by OFX and announced to the market in early February.

Under the proposed scheme, OFX shareholders would receive $1.00 cash per OFX share, representing a $247 million equity value and $233 million enterprise value for the company. The OFX board indicated it intends to unanimously recommend that shareholders vote in favour of the scheme, subject to the parties reaching agreement. For investors following the transaction, the key point is that the proposal remains a scheme process rather than a completed takeover, with the board recommendation tied to final agreement between the parties.

Equals is an FCA-regulated electronic money institution and payment institution in the United Kingdom and an NBB-regulated institution in Belgium. OFX provides money transfer and financial operations services, offering clients real-time financial control and visibility for cross-border business.

OFX shares rose 71.6% to 81.5¢.

Harvest Technology Group (ASX:HTG)

Harvest Technology Group drew significant attention after signing a strategic partnership memorandum of understanding (MOU) with a Ukrainian technology park focused on data transmission under electronic-warfare conditions.

Under the non-binding memorandum with Technopark, a Ukrainian technology and research organisation, the parties intend to explore the adaptation, integration, testing, and potential deployment of Harvest's ultra-low-bandwidth Nodestream platform in unmanned aerial systems (UAS), ground robotic platforms (including counter-mine and demining platforms), and AI-enabled systems.

The proposed cooperation would focus on resilient real-time video, telemetry, and data transmission under electronic-warfare (EW) conditions and severe bandwidth constraints starting from 8 kbit/s, as well as validating Nodestream performance in demanding operational environments. The non-binding structure means the announcement establishes a framework for cooperation rather than confirming a commercial contract, revenue, or deployment timeline.

"This memorandum reflects the growing international interest in Nodestream's ability to deliver resilient communications where bandwidth is scarce and conditions are contested," said Harvest CEO Veronica Bainton.

"It is an early, non-binding step, and any future work will be undertaken strictly in line with our export-control obligations — but it opens a pathway to validate our technology in some of the most demanding operational environments in the world."

HTG shares climbed as much as 15% to 1.2¢.

D3 Energy (ASX:D3E)

D3 Energy attracted investor interest after confirming it had spudded the first of two helium wells at Nooitgedacht in South Africa. The programme will collect additional data on helium and methane concentrations, with drilling aimed at expanding the company's reserve base within the proven ER315 licence area.

Helium is used across specialised industrial, medical, and technology applications, including cryogenics, leak detection, and semiconductor manufacturing, making reserve definition and production approvals central milestones for companies seeking to commercialise helium resources.

D3, composed of experienced Australian oil and gas executives, has already booked reserves to support a production right application lodged last year. The company is positioned along the Homestead Fault, which traverses the northern section of ER315.

"With our production right application accepted for processing by Petroleum Agency SA last year, this drilling programme is about continuing to build the data set that supports the ongoing development of this area as one of the most compelling helium provinces in the world," said MD and CEO David Casey.

D3E shares jumped 17.7% to 36.5¢ at the time of publication.
