After one of the biggest runs on the ASX, this defence stock is slipping again today.
Electro Optic Systems Holdings Ltd (ASX: EOS) shares are under pressure on Thursday following the release of the company's quarterly report.
At the time of writing, the EOS share price is down 3.99% to $9.15.
That pullback comes even as the stock remains one of the market's strongest performers over the past year, up around 660%.
Here's what the company just told investors.

What came through in the quarter
EOS reported a steady flow of new orders across the March quarter, mainly within its defence systems business.
Wins included contracts for remote weapon systems (RWS) and counter-drone capabilities, with several deals landing across key regions.
Many of these orders are scheduled for delivery through 2026 and 2027, giving some visibility on future revenue as production ramps.
The company also flagged the South Korean conditional opportunity worth about US$80 million. Management expects a decision on that contract around mid-2026, though there is no certainty it proceeds.
At the same time, EOS is continuing to expand its global footprint, with discussions underway across Europe, the Middle East, Asia, and the United States.
Order book keeps moving higher
One of the more closely watched metrics for the quarter was the contract backlog.
EOS reported a backlog of $518 million at the end of March, up from $459 million in December. That is a lift of roughly 13% over the prior period.
The increase reflects both recent contract wins and ongoing demand from its core defence platforms.
The company noted that activity levels remained high across manufacturing and delivery, with operations in Australia, the United States, and Singapore all contributing through the quarter.
Cash flow dips despite customer receipts
On the financial side, the numbers were a bit mixed.
Operating cash inflow came in at $9.5 million for the quarter, down from $19.3 million in the December period.
The drop was linked to the timing of milestone payments and increased manufacturing activity as production ramps up.
Customer receipts were solid at $72.6 million, but this was offset by higher operating outflows tied to scaling production and delivery.
EOS ended the quarter with $95.1 million in cash, down from $106.9 million at the end of December.
It also secured a $100 million two-year debt facility earlier this year, giving it more flexibility to manage working capital.
What the market is watching now
The focus now is on timing, especially around the South Korean laser contract.
EOS had expected the US$80 million deal to turn unconditional by the end of March, but that has slipped into the second quarter.
That change likely didn't go unnoticed, given how much attention was on that March milestone.
From here, it comes back to whether EOS can deliver and start turning its backlog into real revenue.
