RF Industries, Ltd. (RFIL) | The Buildout — AI Infrastructure
The Verdict
RF Industries designs and manufactures interconnect products—cables, connectors, assemblies—and integrated systems (cooling, concealment, RF passives) that connect, protect, and cool communications infrastructure. The company’s only direct AI exposure is its Direct Air Cooling (DAC) system, which cools edge computing cabinets and enclosures. Management claims DAC is up to 75% more cost-effective than traditional HVAC, but it is a small fraction of revenue today; the broader business serves wireless carriers, aerospace, and industrial markets.

What We Like
- Record bookings of $26.3M in Q2 FY2026, a multi‑year high, producing a book‑to‑bill of ~1.27x.
- Backlog of $20.1M provides one quarter of revenue visibility and supports management’s guidance for sequential Q3 growth.
- Gross margin expanded to 35.1% in Q2, up 360 bps year‑over‑year, driven by a higher mix of custom cabling and cost‑reduction initiatives.
- Custom cabling—the largest segment—is near historic peak activity, driven by aerospace and industrial demand.
- The cost‑reduction program and supplier negotiations contributed materially to the margin gains and are expected to remain ongoing.
What We’re Watching
- Tariff decisions in July 2026 could raise input costs for Asian‑manufactured connectors; mitigation via source relocation is unproven.
- Aerospace customer at 14% of sales has no minimum purchase agreement; loss would eliminate a material revenue stream.
- Integrated Systems underperformed in Q2 due to small‑cell push‑outs; the backlog‑driven rebound in H2 FY2026 is not yet confirmed.
- DAC remains an early‑stage opportunity with no disclosed revenue or design wins; the 75% cost‑advantage claim is unverified.
The Q2 FY2026 results provide the first concrete evidence that the business has crossed the $20M quarterly revenue threshold where operating leverage becomes meaningful. Record bookings and backlog give near‑term visibility, and management has made explicit promises that will be tested with Q3 results. The thesis is strengthening, but the durability depends on whether bookings momentum persists and whether the DAC cooling opportunity translates into measurable revenue.
Earnings Beat
RF Industries reported Q2 FY2026 revenue of $20.7 million, up 9% year‑over‑year, with gross margin of 35.1% compared to 31.5% a year earlier. GAAP net income swung to $879 thousand from a loss of $245 thousand in the prior-year period, while bookings jumped to a multi-year high of $26.3 million.

In Q2, we achieved over $26 million in bookings our strongest bookings quarter in many years. Let that sink in.— Ray Bibisi, COO, June 15, 2026
Management tone: Management’s tone shifted from recovery-oriented to emphatic confidence. COO Ray Bibisi pointedly paused the call to underscore record bookings, and CEO Robert Dawson framed the DAC product as a ‘game changer’ while candidly acknowledging Integrated Systems underperformance and limited visibility into the aerospace customer’s ordering schedule.
Management Guidance
Management guided for Q3 FY2026 revenue to increase sequentially over Q2 ($20.7M). They expect Integrated Systems activity to accelerate in the back half of the year, small-cell shipments to resume and increase, and the margin and earnings trajectory to be sustainable. The CFO stated an intent to reduce net debt to an immaterial level, with inventory conversion expected to improve working capital.
Trajectory
Revenue grew from $18.9M in Q2 FY2025 to $20.7M in Q2 FY2026, while gross margin expanded from 31.5% to 35.1% over the same period. The improvement was driven by a higher mix of custom cabling, cost‑reduction initiatives, and the operational leverage that management had long argued would materialize once the business crossed $20M in quarterly revenue. The trailing twelve months ended with $82.2M in revenue and EBITDA of $5.3M (6.4% margin).
The Model
The model projects FY+1 revenue of $86.2 million and EBITDA of $7 million (8.3% margin), anchored by backlog of $20.1M and recent bookings strength. For FY+2, revenue rises to $97.0 million with EBITDA of $10 million (9.9% margin), implying further operating leverage as the company scales and potential contributions from DAC and integrated systems opportunities materialize.

What Could Go Right — and Wrong
- Custom cabling demand from aerospace and industrial stays near peak levels, raising the revenue base well above $20M per quarter.
- DAC cooling converts from trials to a named design win with a data center operator, adding a new growth vector.
- Large multi‑site integrated systems contracts are awarded, providing a step‑up in revenue and proving the turnkey solutions model.
- Tariffs prove manageable, and source‑relocation efforts preserve margin expansion.
- Inventory releases and cash flow improvement allow net debt to drop to zero ahead of schedule.
- The record bookings quarter proves unrepeatable, and backlog depletes without replenishment, causing revenue to stall below $20M per quarter.
- The aerospace customer reduces orders or shifts to another supplier, erasing 14% of sales.
- Small‑cell push‑outs persist into H2 FY2026, preventing the Integrated Systems rebound management expects.
- July 2026 tariff decisions raise costs for Asian‑sourced connectors, compressing gross margins back toward 30%.
- DAC remains a niche product with no material revenue, negating the AI‑adjacent growth narrative.
Looking Ahead
The next twelve months offer multiple milestones. The Q3 FY2026 report will be the first direct test of management’s explicit sequential‑growth promise. The second half of the fiscal year is expected to bring an Integrated Systems rebound as small‑cell shipments resume, while DAC trials continue to advance. External events—a July tariff decision and an August court hearing on the class‑action settlement—carry short‑term risk. Further out, the conversion of large multi‑site integrated systems opportunities into awards could materially change the company’s revenue trajectory.
- July 2026US tariff decisions — New tariffs could raise input costs; test of supply‑chain relocation efforts.
- August 7, 2026Class action settlement hearing — Preliminary approval of $855K settlement would remove legal overhang.
- ~September 2026Q3 FY2026 earnings report — First test of management’s promise of sequential revenue growth above $20.7M.
- H2 FY2026Integrated Systems acceleration — Rebound in small‑cell and DAC shipments is needed to validate back‑half outlook.
- OngoingDAC trial conversions — If trials lead to design wins, DAC could become a quantifiable revenue contributor.
- Not datedLarge multi‑site contract awards — Turnkey integrated systems awards could deliver ‘meaningful incremental revenue’ per CEO.

The Company
RF Industries manufactures and markets engineered interconnect products—coaxial, fiber‑optic, and copper cables, connectors, and assemblies—and integrated systems that include thermal cooling, concealment, and passive RF components. These products connect, protect, and cool the physical infrastructure of wireless networks, data centers, and industrial facilities. The company’s only link to AI infrastructure is its Direct Air Cooling (DAC) system, a patented unit that cools edge‑computing cabinets at a cost management claims is up to 75% below traditional HVAC. DAC is a small fraction of revenue but is described as a growth vector for the next one to two years.
RFIL operates five US‑based manufacturing and design facilities in California, New York, Connecticut, New Jersey, and Rhode Island, holding ISO and AS9100 certifications. Final assembly and integration are performed domestically, while substantially all of its RF connector products are sourced from third‑party contract manufacturers in Asia without long‑term agreements. The company relies on Corning as its primary fiber supplier and maintains a Corning Gold certification. It divides its sales across wireless carriers, aerospace and defense, industrial OEMs, and distributors.
Business Segments
Competitive Landscape
RFIL competes in interconnect and thermal management markets dominated by larger players. It differentiates through custom‑engineered solutions and US‑based assembly, which can be an advantage for defense ‘Buy American’ requirements. However, in the commodity connector business it is one of many suppliers; its reliance on Asian contract manufacturing without long‑term agreements is a vulnerability that larger, vertically integrated competitors do not share.
