CI Systems in the First Quarter: Customer Collections Lift Cash While Microelectronics Backlog Falls
CI Systems opened 2026 with 18% revenue growth and $4.1 million of operating cash flow, mainly from lower receivables and higher customer advances. Underneath that cash improvement, microelectronics posted a $1.4 million segment loss and backlog fell to $2.6 million, so WETALYZER still needs repeat orders.
The first quarter gives a clearer answer to two questions left open after 2025 for CI Systems: the defense and scientific segment still carries sales and segment profit, while WETALYZER has not yet refilled the backlog after the first order wave. Revenue rose 18% to $12.1 million, but operating profit swung to a $352 thousand loss because microelectronics investment, dollar-denominated pressure from shekel costs, and U.S. tariffs moved faster than revenue in the newer segment. Cash was much better: operating cash flow reached $4.1 million, mainly from a $2.8 million reduction in receivables and a $670 thousand increase in customer advances. That is a real balance-sheet improvement, not proof that the business is already more profitable. Total backlog fell to $31.7 million, of which $29.1 million sits in defense and scientific equipment. For now, 2026 looks like a well-funded proof year: the company has $15.0 million of cash and no bank financial debt, but the market will need to see repeat microelectronics orders and less pressure from the shekel before this quarter can be read as the start of a new step-up.
Defense Carries Sales While WETALYZER Carries Costs
CI Systems sells electro-optical testing and measurement equipment in three areas: defense and scientific equipment, microelectronics equipment, and remote sensing equipment. In this quarter, the economic map is simpler than the formal reporting structure. Defense and scientific equipment generated 85% of sales, 87% of segment gross profit, and all positive segment profit. Microelectronics is the strategic option, mainly around WETALYZER and WETSPEC, but it is still consuming more expense than it returns in profit.
Defense and scientific equipment generated $10.3 million of sales, up 19.5% year over year, and kept gross margin at 33.6%. The largest customer, Elbit Systems, rose to 24.4% of consolidated sales, compared with 21.9% for full-year 2025. That is not inherently negative. For a niche defense-equipment company, a high-quality anchor customer and long backlog can be an asset. The point is that this anchor explains near-term visibility much more than the semiconductor-equipment products do.
Microelectronics sales rose only to $1.5 million, up 7.8% year over year, while gross margin fell to 22.5% from 34.1%. The segment loss widened to $1.4 million. This is not only a sales issue: the company expanded infrastructure, headcount in Israel and abroad, development expense, and marketing expense, while also absorbing the weaker dollar against the shekel. The product milestones were positive. Additional WETALYZER systems received customer acceptance, started operating on production lines, and generated revenue recognition. The company also sold WETSPEC units into advanced packaging and placed additional demo systems. Those milestones matter, but they do not yet turn the segment into a recurring profit source.
| Segment | Q1 2026 Revenue | YoY Change | Segment Profit or Loss | Backlog at March 31, 2026 | What It Means |
|---|---|---|---|---|---|
| Defense and scientific equipment | $10.274 million | 19.5%+ | $2.030 million profit | $29.1 million | The profit and visibility engine for 2026 |
| Microelectronics | $1.526 million | 7.8%+ | $1.409 million loss | $2.6 million | Product and market investment before repeat-order proof |
| SENSING | $334 thousand | 22.8%+ | $106 thousand loss | $52 thousand | Still too small to change the thesis |
Microelectronics Backlog Fell After the First Order Wave
In the prior annual analysis, the open question was whether WETALYZER would move from a first sale into a repeat-order path. The first quarter closes one part of that question and leaves the more important part open. The company has supplied systems, received customer acceptance, and recognized revenue. Those steps reduce the technology and execution risk around the first sale.
The backlog is less comfortable. Microelectronics backlog fell to $2.6 million at the end of March 2026, compared with $2.75 million at the end of 2025 and $6.9 million at the end of March 2025, which included $4.3 million of WETALYZER orders that were mostly received in the first quarter of 2025. The company also says delays in developing additional WETALYZER applications are extending the time to receive orders beyond its expectations.
That is the difference between a product entering a customer and a product beginning to recur in orders. In semiconductor equipment, customer acceptance at the first account is important, but the value step arrives when the same customer or additional customers order again. For now, microelectronics revenue exists, investment exists, and the backlog does not confirm refill. The quarter therefore strengthens the proof that the product works at a customer. It does not yet prove demand is recurring fast enough to cover the new infrastructure.
This also explains the difference between the operating headline and the market question. A revenue-only read sees growth. A source-of-growth read shows that defense is still most of the story, while microelectronics needs more orders, not just more acceptances.
Collections Fill the Cash Balance, Not Operating Profit
Cash flow is the strong part of the quarter, and it is strong for a different reason than profitability. CI Systems generated $4.1 million of operating cash flow, after using $2.1 million in the comparable period. The core sources were a $2.845 million reduction in receivables, a $670 thousand increase in customer advances, and a $621 thousand increase in suppliers. Economically, customers paid, advances came in, and suppliers funded part of the cycle. That matters more than quarterly net profit because it helps the company finance the microelectronics investment phase without relying on immediate bank debt.
All-in cash flexibility was positive even after investment and lease cash uses. Starting from operating cash flow, subtracting $470 thousand of property and equipment purchases, $10 thousand of intangible asset purchases, and $200 thousand of lease repayments, then adding $24 thousand of proceeds from fixed-asset disposals, leaves roughly $3.4 million of cash addition before exchange-rate effects. This is not normalized cash generation from the underlying business because it relies heavily on customer collections and advances. It is still a useful funding cushion for quarters in which microelectronics needs more development, employees, demo systems, and local coverage.
The operating pressure runs through the shekel. The average dollar exchange rate in the quarter fell to NIS 3.122, compared with NIS 3.612 in the comparable quarter and NIS 3.45 in 2025. Because part of the salary base and expenses are in shekels, a weaker dollar raises dollar-denominated costs. The company adds that after the balance-sheet date the dollar fell to roughly NIS 2.8, with a large effect on shekel expenses in dollar terms. Finance expense also moved against the company: net finance expense was $239 thousand, compared with net finance income of $79 thousand in the comparable quarter, and part of the amount came from shekel-indexed leases that increase the dollar liability when the dollar weakens.
There was also an asset and capacity move after the balance-sheet date. On May 11, 2026, the company signed a lease for an additional industrial building in Migdal HaEmek, with about 2,000 square meters of built area. The lease is expected to begin on July 1, 2026, subject to handover, and the company will also buy installed equipment and systems from a third party for about NIS 800 thousand. After taking possession, the company’s leased area in that industrial zone will total about 6,800 square meters. That does not mean revenue rises immediately, but it does show the company expanding its operating base while the new segment is still loss-making.
2026 Depends on Repeat Orders and the Shekel
The first quarter does not weaken CI Systems as a niche equipment company with a strong cash balance and large defense backlog. It moves the debate from whether there is growth to what quality that growth has. Revenue is rising, but microelectronics profitability is weaker, backlog in that segment is down, and the company is still carrying the cost of a broader infrastructure. On the positive side, receivable collections and customer advances give the company time and cash to build the product without immediate debt pressure.
The number that can change the market read over the next few quarters is microelectronics backlog refill. A WETALYZER repeat order, an additional customer, or a clear rise in the segment backlog would be different from customer acceptance for systems already supplied. Without that, 2026 remains mainly a year in which defense funds the semiconductor-equipment option.
The counter-thesis is fair: some microelectronics orders may be delivered quickly and therefore may not sit in backlog for long, and investments in Taiwan, Korea, and demo systems may begin to bring orders later in the year. The current evidence leans more cautious. A $29.1 million defense backlog, $15.0 million cash balance, and strong customer collections give the company a good base. A $2.6 million microelectronics backlog, $1.4 million segment loss, and heavy shekel pressure mean the new product still needs to show commercial payback.
