Structural Monitoring Systems Initiated by Evolution Capital: Peer Valuations Highlight Potential Upside

Structural Monitoring Systems Plc (ASX:SMN) has received fresh analyst attention, with Evolution Capital initiating coverage on the aerospace electronics company in a new research report examining its position within the global avionics sector. 

Importantly, the coverage was initiated independently by Evolution’s analyst rather than commissioned by the company, a distinction that often carries additional credibility with institutional investors. 

The report places Structural Monitoring Systems alongside a number of established international aerospace electronics companies — and highlights a notable valuation gap between SMN and its global peers. 

A Rare ASX Exposure to Aerospace Electronics 

Structural Monitoring Systems occupies a unique position on the Australian market. 

Through its Canadian subsidiary Anodyne Electronics Manufacturing (AEM), the company designs and manufactures specialised avionics equipment including cockpit audio systems, aircraft radios and communications hardware used across aerial firefighting, emergency services and mission aviation fleets. 

Unlike many technology companies at similar market capitalisations, the business is already generating meaningful revenue and positive operating cash flow. 

For the half-year ended 31 December 2025 the company reported: 

• Revenue of approximately $16.5 million, up 31% year-on-year 

• Underlying operating profit of around $1.4 million before non-cash depreciation impacts 

• Free cash flow of approximately $3.4 million 

Operational discipline was also evident through improved working capital management, including a material reduction in inventory during the period. 

These results suggest the avionics division is beginning to demonstrate operating leverage as production volumes scale. 

 

Global Peer Comparison 

One of the most notable aspects of Evolution Capital’s initiation note is its comparison of Structural Monitoring Systems with established avionics suppliers listed in the United States. 

The report references companies including: 

Company	Ticker	Exchange	EV / EBITDA
TransDigm Group	NYSE: TDG	New York	~20–25×
HEICO Corporation	NYSE: HEI	New York	~25–35×
Astronics Corporation	NASDAQ: ATRO	Nasdaq	~15–20×
Ducommun Incorporated	NYSE: DCO	New York	~12–16×

These companies operate within the same aerospace supply chain, producing certified aircraft electronics with long product lifecycles and recurring aftermarket demand. 

Structural Monitoring Systems currently trades at an estimated ~6–7× EV/EBITDA, placing it at a substantial discount to the valuation multiples typically assigned to global avionics businesses. 

While differences in scale remain, the comparison highlights how the market may still be valuing SMN more like a small-cap industrial company than a participant in the aerospace electronics sector. 

 

AEM: The Operating Engine 

Evolution’s analysis emphasises the growing importance of the AEM avionics division as the primary earnings driver of the group. 

AEM’s products are already deployed across specialised aviation segments including firefighting aircraft, emergency response fleets and mission aviation operators. 

Recent regulatory approvals for the MTP136D radio from the United States Forest Service and Department of the Interior expand the potential addressable market to federally regulated aerial firefighting aircraft across the United States. 

Given the size of the federal and contractor firefighting fleet, the approval significantly increases the potential customer base for the product. 

 

CVM Technology Provides Strategic Optionality 

Alongside its avionics operations, Structural Monitoring Systems continues developing its Comparative Vacuum Monitoring (CVM™) structural health monitoring technology. 

The system is designed to detect microscopic cracking in aircraft structures and is currently progressing through regulatory pathways for potential application on the Boeing 737NG aft pressure bulkhead. 

In Delta Air Lines’ case, the 737NG fleet installation program has now been completed across 64 aircraft, representing full fleet deployment. United Airlines has also completed installations across a number of aircraft, while potential programs with Southwest and other carriers remain contingent on final FAA certification outcomes. 

These fleet integrations represent an important operational milestone and provide real-world validation of the technology in active airline service. The installations establish an early installed base across major global carriers, positioning the company favourably should regulatory approval unlock broader adoption across the global 737NG fleet. 

For now, analysts typically treat CVM as long-term optionality rather than near-term revenue, meaning the company’s current valuation is largely anchored to its avionics business. 

 

A Valuation Gap the Market May Eventually Revisit 

Evolution Capital’s initiation note effectively reframes Structural Monitoring Systems within its global aerospace peer group rather than among traditional ASX small-cap industrials. 

For investors seeking exposure to the aerospace supply chain — a sector largely dominated by US-listed companies — SMN represents one of the few domestic listings operating within that ecosystem. 

If the company continues to demonstrate consistent growth and cash generation from its avionics operations, the valuation gap highlighted in Evolution’s peer analysis may increasingly attract investor attention.
