Boeing delay leaves SMS CVM commercialisation timetable unresolved

Boeing approval delay clouds weaker quarterly result

Structural Monitoring Systems Plc (ASX:SMN) has opened FY27 with a less forgiving operating backdrop: quarterly revenue fell to A$7.0 million from A$8.1 million, while net profit after tax dropped 42% to A$0.7 million. Adjusted EBITDA declined 14% to A$1.8 million and free cash flow fell 56% to A$0.7 million, according to unaudited management accounts.

The more consequential setback sits in the company’s structural health monitoring ambitions. Boeing has advised that competing certification priorities have delayed the FAA’s review of the service bulletin for the 737NG aft pressure bulkhead application. SMS said the approval pathway is taking longer than previously anticipated, remains outside its control and has no revised completion date.

The timing matters because the CVM technology is still at the evaluation and regulatory stage. SMS recorded sales of CVM equipment, test products and sensors to the FAA during the quarter, received a purchase order from a major defence aircraft manufacturer and submitted a quotation to another aircraft manufacturer. The company stressed that these activities relate to evaluation and research, with any commercial deployment still subject to further development and regulatory processes.

Avionics sales absorb maintenance delays

Avionics revenue was A$3.8 million, down 25% on the reported prior-year figure and 17% lower excluding foreign exchange movements. Management attributed part of the reduction to aircraft remaining in critical-mission operations for longer than expected, delaying maintenance and upgrade work. A 9% year-on-year weakening in the Canadian dollar also reduced the Australian-dollar value of the Canadian operations.

The comparison is not entirely clean: Q1 FY26 revenue included A$1.4 million carried over from June 2025 because of a customs delay. Even so, the quarter contained some useful offsets. Loudspeaker-system sales rose 32% on the prior corresponding period, driven by international aircraft manufacturers, while contract manufacturing revenue increased 15% excluding foreign exchange movements. The company expects radio sales to be at or above the prior corresponding period in the second quarter.

SMS is also working towards international adoption of its MTP138 radio, with the first targeted application expected to receive Transport Canada approval at the beginning of Q3 FY27 and EASA approval to follow. That timetable builds on the earlier MTP138 radio launch, which targeted offshore and marine markets.

Self-funded product investment increases

The weaker quarter did not prompt SMS to retreat from development spending. AEM, its wholly owned Canadian subsidiary, invested A$0.8 million in product development, up from A$0.3 million a year earlier, while the two new avionics programmes remained on schedule. Product introductions are targeted for late FY27 and early FY28, subject to development progress and certification.

The balance sheet provides some room for that investment: cash at bank rose to A$5.2 million from A$4.8 million at 30 June, and the group said it had repaid all borrowings. That financial position follows the record FY26 result, which included A$6.0 million of free cash flow and zero bank debt.

For now, SMS is funding development from an operating business that remains profitable and cash generative. The sharper test is whether delayed maintenance activity reverses in the next quarter, and whether higher investment produces certified products on schedule while the Boeing and FAA process continues without a stated endpoint.
