Federal Treasurer Jim Chalmers has responded to these developments, acknowledging the need to support founders and venture capital investors. "We are committed to ensuring that start-up companies and their founders feel valued and supported," Chalmers stated, hinting at potential policy adjustments. This comes amidst concerns that the current scenario might drive start-ups to seek opportunities overseas.

Despite these macroeconomic and geopolitical discussions, several ASX-listed companies have reported significant milestones in their growth and commercialisation strategies.

EBR Systems Inc (ASX:EBR)

EBR Systems Inc. has made a notable advancement in its U.S. commercial rollout of the WiSE® CRT System by securing a purchasing agreement with HCA Healthcare. HCA Healthcare, one of the largest healthcare networks in the U.S., operates 190 hospitals and approximately 2,500 ambulatory sites across 19 states. This agreement provides EBR with a streamlined procurement and contracting pathway across this major hospital network.

"The agreement builds on EBR’s growing commercial momentum and is expected to support broader hospital access across the HCA network," an EBR spokesperson commented. This development follows the commencement of U.S. reimbursement for WiSE and allows EBR sales representatives to engage directly with physicians and administrators at HCA sites, further promoting the adoption of the WiSE System. Already active in two HCA sites, St David’s Medical Center in Austin, Texas, and Medical City in Fort Worth, Texas, EBR Systems is poised for broader expansion.

Megaport Limited (ASX:MP1)

IT services group Megaport has experienced a strong week, driven by its robust global automated infrastructure platform. This platform spans over 1,100 data centre locations, offering rapid deployment, ultra-low latency, and dedicated high-performance infrastructure critical for large enterprises and global hyper-scalers.

The company's share price surged following the announcement that its wholly owned subsidiary, Latitude.sh, secured three major contracts involving Graphics Processing Units (GPU), Central Processing Units (CPU), network, and storage across two customers. "These contract wins affirm Megaport’s position as a critical infrastructure partner in the accelerating AI ecosystem," a company representative noted. The contracts, which align with Megaport’s infrastructure and capital deployment strategies, are binding and cover fixed terms, ensuring committed long-term revenue irrespective of usage.

Additionally, Megaport reaffirmed its FY26 Group Revenue and EBITDA guidance, initially released with its H1 FY26 results in February 2026, further boosting investor confidence.

Nexsen Limited (ASX:NXN)

Biotechnology company Nexsen has also garnered attention, with increased buying interest following its strategic collaboration framework with GHK Hospital Limited, a subsidiary of IHH Healthcare Berhad. Nexsen is developing rapid point-of-care diagnostics designed to deliver lab-grade results for conditions traditionally reliant on delayed laboratory testing.

"The collaboration will support the clinical validation, real-world data generation, and potential commercialisation of Nexsen’s rapid point-of-care diagnostic platform across North Asia," a Nexsen spokesperson explained. This partnership grants Nexsen access to relevant patient populations and real-world hospital workflows, aiding in the progression of clinical validation and the generation of real-world evidence. It also opens opportunities for joint R&D, grant applications, and co-development of future diagnostic products beyond Nexsen’s initial development pipeline.

Carnaby Resources Limited (ASX:CNB)

In the materials sector, small-cap explorer Carnaby Resources has seen its stock trend higher, driven by promising developments at its copper and gold projects in Queensland and Western Australia. The company announced further high-grade copper-equivalent exploration drill results from its Trekelano Project in Mt Isa, Queensland.

These results confirm the discovery of a significant new Footwall Lode, first intersected in 2025, which remains open down plunge and along strike to the north. "All new results, including the original discovery hole, are outside of the existing Mineral Resource Estimate," a company representative highlighted. The new Trek 1 Footwall Lode is open up dip to the Ore Reserve Open Pit, with potential to expand the Ore Reserve open pit. With further drill results pending and ongoing drilling activities, Carnaby Resources anticipates more positive developments.

As the week concludes, these ASX-listed companies continue to make strides amidst the backdrop of federal budget discussions, highlighting the dynamic nature of the investment landscape.
