Key Highlights

  • Silex Systems is a Sydney-based technology commercialisation company built around SILEX — Separation of Isotopes by Laser EXcitation — a third-generation laser uranium enrichment process that uses precisely tuned lasers, rather than high-speed centrifuges, to separate isotopes.
  • Electro Optic Systems is a Canberra-headquartered defence and space technology group: its Defence Systems division makes remote weapon systems (RWS) — stabilised, remotely operated gun mounts — plus counter-drone technology and high-energy laser weapons, while Space Systems builds optical sensors for tracking objects in orbit.
  • Weebit Nano develops ReRAM — resistive random-access memory — an emerging class of non-volatile memory built from what the company calls fab-friendly materials.
  • The three businesses combine different Revenue models, Capital needs and execution priorities within the technology sector.

Silex Systems (ASX:SLX), Electro Optic Systems Holdings (ASX:EOS) and Weebit Nano (ASX:WBT) approach FY2027 from different operating positions. Their latest company disclosures show how revenue quality, cash conversion and delivery against announced programs matter more than a shared sector label.

Each company is assessed on its own reporting calendar and Business model. The discussion below retains company-reported financial measures and announced plans while separating those facts from assumptions about future outcomes.

Company Business

Silex Systems Limited (ASX:SLX)

Silex Systems is a Sydney-based technology commercialisation company built around SILEX — Separation of Isotopes by Laser EXcitation — a third-generation laser uranium enrichment process that uses precisely tuned lasers, rather than high-speed centrifuges, to separate isotopes.

Electro Optic Systems Holdings Limited (ASX:EOS)

Electro Optic Systems is a Canberra-headquartered defence and space technology group: its Defence Systems division makes remote weapon systems (RWS) — stabilised, remotely operated gun mounts — plus counter-drone technology and high-energy laser weapons, while Space Systems builds optical sensors for tracking objects in orbit.

Weebit Nano Limited (ASX:WBT)

Weebit Nano develops ReRAM — resistive random-access memory — an emerging class of non-volatile memory built from what the company calls fab-friendly materials. As chipmakers move to advanced process nodes, embedded flash becomes difficult and costly to manufacture, and ReRAM offers a lower-power, more scalable alternative for microcontrollers, IoT devices, automotive systems, aerospace and defence, and edge AI.

Financial Performance

Silex Systems Limited (ASX:SLX)

Silex does not operate an enrichment plant; the uranium application is licensed to Global Laser Enrichment LLC (GLE), a US joint venture 51 per cent owned by Silex and 49 per cent by Canadian uranium producer Cameco Corporation, which Silex consolidates as a majority-owned, still pre-revenue vehicle.

Silex is entitled to a minimum 7 per cent perpetual Royalty on GLE's future enrichment revenues, plus milestone payments tied to commercial development stages — its half-year accounts to 31 December 2025 recorded a A$7.6 million payment after GLE achieved Technology Readiness Level 6 (TRL-6). Smaller programs apply the same platform to zero-spin silicon for Quantum Computing and to medical isotopes; neither is yet material to reported revenue.

Electro Optic Systems Holdings Limited (ASX:EOS)

Revenue is contract-based: EOS wins defence procurement contracts, then recognises revenue as it manufactures and delivers, and the gap between award and recognition can run to years — why the company reports an order book of unconditional contracted future work.

EOS announced the sale of its satellite communications Subsidiary to UK-listed Cohort plc in November 2024 at an Enterprise value of A$144 million, completing on 31 January 2025 for A$158.6 million — higher than announced because of contract balance adjustments. FY2025 accounts recorded net proceeds of A$153.3 million; part repaid a A$64.4 million Facility owed to Washington H. Soul Pattinson, leaving EOS without borrowings at that point.

Weebit Nano Limited (ASX:WBT)

Weebit does not build chips; it licenses ReRAM as semiconductor IP to foundries and integrated device manufacturers. Revenue therefore arrives in several distinct forms: upfront licence fees, non-recurring engineering and design fees, milestone payments as technology transfer and qualification stages complete, and — eventually, if customer products reach Volume Manufacturing — per-wafer royalties.

That last leg has not yet arrived at scale: a signed licence agreement is not the same as recognised revenue, and recognised licence revenue is not the same as recurring royalty income.

Sector Context

The companies serve different parts of the technology economy, so their revenue and cost structures are not directly interchangeable. Contract duration, recurring income, customer concentration, Capital Expenditure and Acquisition accounting can materially change how headline growth appears in each set of accounts.

A useful comparison therefore starts with the source of revenue and the cash required to support it. Reported guidance remains conditional on management execution, customer activity and the timing of announced projects or integrations.

Risks to Consider

Silex Systems Limited (ASX:SLX)

Silex is exposed to a single dominant asset whose value depends on regulatory approval not yet granted, and nuclear licensing timelines routinely extend beyond the company's control.

Electro Optic Systems Holdings Limited (ASX:EOS)

The distinction between an award and recognised revenue is the central risk: an A$846 million order book is contracted work, not cash in hand, and the 27 per cent FY2025 revenue decline after a large contract finished shows how quickly a delivery cycle can turn.

Weebit Nano Limited (ASX:WBT)

A A$54.9 million annual loss against A$167 million of cash implies a finite runway absent a sharp revenue step-up or further raisings, and the 2026 pattern of a Placement followed by an SPP shows how the company has closed that gap.

What to Watch Next

Silex Systems Limited (ASX:SLX)

This is not product revenue, but largely recoverable project costs charged through the GLE structure, government grants and milestone payments.

In August 2025 Silex completed a A$130 million institutional placement at A$3.90 per share, part of A$142.7 million raised across the December 2025 half-year, and said it planned to inject A$188.2 million into GLE's commercialisation program, plus A$26.4 million for other isotope opportunities and working capital, expecting to be funded to the end of FY2028.

Electro Optic Systems Holdings Limited (ASX:EOS)

EOS booked an A$60 million counter-drone order in March 2026, around A$170 million of new counter-drone command-and-control contracts for MARSS, and roughly A$188 million in new MARSS orders booked after completion, while BAE Systems selected the NiDAR C2 system for a next-generation platform.

In FY2025, revenue from continuing operations fell 27 per cent to A$128.5 million as a major Middle East contract completed; the underlying EBITDA loss was A$24.4 million, the post-tax loss from continuing operations A$73.5 million, and Space Systems revenue excluding EM Solutions A$12.7 million. Cash rose to A$106.9 million from A$52.3 million, helped by the divestment, and the unconditional order book stood at about A$459.1 million at 31 December 2025.

Weebit Nano Limited (ASX:WBT)

In February 2026 Weebit confirmed the customer as Texas Instruments, a Tier-1 integrated device manufacturer, covering IP licensing, technology transfer, and design and qualification of Weebit ReRAM in TI's advanced process nodes; financial terms were not disclosed. Weebit also reported first test chips from onsemi performing as expected.

In March 2026 its ReRAM was selected for a Korean national compute-in-memory program. By May 2026 two product customers had taped out designs, one already demonstrating a functional prototype; by the July 2026 quarterly a third tape-out was complete, with one returned design fully functional and able to run software, targeting smart battery management and cybersecurity.

How to Read the Current Position

The clearest assessment will come from subsequent company reporting. Revenue should be read alongside margins and cash flow, while acquisition-led growth should be distinguished from organic activity. Guidance and longer-term targets are company objectives rather than assured outcomes.
