RF Industries posted record quarterly revenue of $23.96M (+21.1% YoY) and tripled net income to $1.44M, but a one-time tariff refund accounts for most of the 160bp gross-margin gain and a 5.5% tax rate understates normalized earnings.
Record quarter, but most of the margin gain was a one-time tariff refund
RF Industries — a San Diego maker of connectors, cable assemblies and wireless-site equipment — reported its highest-ever quarterly revenue for the three months ended July 31, 2026 (its fiscal third quarter; the company's financial year ends October 31). Net sales rose 21.1% to $23.96 million from $19.79 million a year earlier, operating income more than doubled to $1.76 million, and net income was $1.44 million ($0.12 per diluted share) against $392,000 ($0.04) last year.
The growth is real and it came from the two product lines the company actually controls. The margin improvement, however, is mostly not: strip out a $0.3 million refund of previously paid import tariffs and gross margin was 34.2% versus 34.0% a year ago — essentially flat.

Gross margin is the share of revenue left after the direct cost of making the product. Operating margin is what's left after those costs plus engineering, selling and administrative expenses — before interest and tax. "bps" means basis points; 100 bps = 1 percentage point.
What actually drove the quarter
Two of the three product lines grew, and one shrank:
Custom Cabling (built-to-order cable and wiring assemblies, usually sold on large project purchase orders) rose $2.9 million to $10.1 million. Management attributes this to "organic growth in industrial market segments and increased demand from a tier one carrier." This line is now 42% of sales, up from 36%.
Interconnect (standardized connectors and cables that customers reorder routinely) rose $1.6 million to $7.8 million, "primarily driven by more wireless infrastructure deployments." This is the company's steadiest revenue stream, so growth here is the highest-quality part of the quarter.
Integrated Systems (small-cell enclosures, thermal cooling and related site solutions) fell $0.4 million to $6.0 million, on "a decrease in sales of small cell solutions to our wireless carrier customers due to the timing of orders and shipments based on budget cycles, offset by an increase in thermal cooling within the same ecosystem."
That last line is the one to watch. Over the nine months to July 31, Integrated Systems is down 22.4% ($17.0 million versus $21.9 million) because of "timing delays in small cell deployments within tier one wireless carriers." The quarterly decline of 6.7% is a much milder version of the same problem, which suggests the drag is easing rather than ending — but the company is still growing despite its highest-value product line, not because of it. Nine-month revenue growth of 9.9% is a fairer picture of underlying momentum than the quarter's 21.1%.
Geographically the business is almost entirely domestic: US sales of $21.8 million versus $18.4 million, with foreign sales of $2.2 million (mostly Canada, $1.8 million) up from $1.4 million.
The margin story is smaller than the headline
Reported gross margin of 35.6% looks like a clean 160 basis point improvement. The filing is explicit that $0.3 million of it is a refund of import tariffs the company had previously paid, booked as a reduction to cost of goods sold, and that normalized gross margin was 34.2%. So roughly seven-eighths of the apparent margin expansion is a one-off cash recovery that will not repeat.
What is durable is operating leverage — revenue growing faster than fixed costs. Total operating expenses rose 13.0% to $6.78 million while sales rose 21.1%, so opex fell to 28.3% of sales from 30.3%. Selling and general expenses of $5.71 million were 23.8% of sales versus 26.5%, even though the dollar amount rose $0.5 million on higher sales commissions and bonuses, public-company fees and stock compensation. Engineering spending rose 41% to $1.07 million on new product development — a deliberate increase, and the one expense line growing faster than revenue.
Even excluding the tariff refund, operating income would have been roughly $1.46 million versus $0.72 million. The doubling of operating profit is genuine; the margin level is flattered.
One more adjustment worth making: operating income of $1.76 million is after $411,000 of quarterly amortization of acquired intangible assets — a non-cash accounting charge from past acquisitions that runs at about $1.6 million a year and says nothing about current operations. Cash earning power is meaningfully above the GAAP line.
The tax rate is temporarily fictional
RF Industries paid an effective tax rate of 5.5% this quarter versus 18.3% last year. This is not a tax strategy — it is the mechanical result of a valuation allowance, an accounting reserve a company books against its accumulated tax benefits (mostly past losses) when it doubts it will earn enough future profit to use them. While that allowance is in place, profits are largely shielded and reported tax expense stays minimal.
The filing flags that this is about to change. Management notes the company "has generated pre-tax income in each of the most recent four consecutive fiscal quarters" and that if profitability holds, "a reduction of a significant portion of the valuation allowance may be appropriate in a future reporting period," which "could result in a material income tax benefit in the period recognized."
For investors this cuts two ways, and both matter:
One quarter of inflated earnings. Releasing the allowance produces a large non-cash tax benefit, which will show up as a one-off jump in net income and EPS. It is a bookkeeping event, not cash.
Permanently lower reported earnings afterward. Once the allowance is gone, the tax line normalizes. At a more typical ~25% blended rate, this quarter's $1.53 million of pre-tax income would have produced roughly $0.10 of diluted EPS rather than the $0.12 reported. Anyone modelling forward EPS off the current tax rate will be about 20% too high.
Note also that the diluted share count rose 7.7% year over year, to 11.6 million. With the stock's options now well in the money (aggregate intrinsic value of outstanding options was $8.5 million at July 31), dilution is expanding, and per-share growth will keep lagging net-income growth.

The company repaid $2.1 million on its revolving credit facility during the nine months, cutting net debt (borrowings minus cash) from roughly $2.8 million to $1.3 million. Working capital is $18.4 million and the current ratio — current assets divided by current liabilities, a rough measure of near-term solvency — is about 2.0:1. The revolver was amended in November 2025 to extend maturity to March 2029 and lower the interest rate, which is why quarterly other expense (essentially interest) was flat at $233,000 even as the business grew.
The soft spot is receivables. Nine-month operating cash flow was only $1.6 million against $2.3 million of net income, because accounts receivable consumed $2.2 million. At $17.0 million against a $24.0 million quarter, receivables represent roughly 65 days of sales — the growth is being financed, at least temporarily, by letting customers pay later. Inventories fell slightly, which is the healthier signal: the revenue increase is not being manufactured by building stock.
Two obligations sit outside the debt line and are larger than it. Operating lease liabilities total $17.5 million (with $22.2 million of future minimum lease payments), and goodwill plus intangible assets total $18.3 million, or about 47% of shareholders' equity — a reminder that a chunk of the balance sheet is acquisition accounting rather than operating assets.
The California wage-and-hour class action is close to resolved: an $855,000 all-in settlement was accrued back at October 31, 2025, preliminary court approval was granted August 7, 2026, and final approval is scheduled to be heard January 22, 2027. No further earnings impact is expected.
Structure: now a single segment
Following the fiscal 2025 restructuring — consolidated manufacturing, headcount reductions and a unified sales organization — the company reports as one segment rather than the previous two. That restructuring is visibly showing up in the numbers: the nine-month swing from a $98,000 net loss to $2.3 million of net income came from $5.7 million more revenue against only $1.4 million more operating expense.
Takeaway: The quarter's 21% revenue growth is genuine and broad-based across the two steadier product lines, but almost all of the 160 basis point gross-margin gain was a non-repeating tariff refund, and the 5.5% tax rate understates future tax cost by roughly 20 percentage points. Normalize for both and RF Industries is a business earning about $0.10 a share on flat-ish ~34% gross margins with real operating leverage — improving, but not at the run-rate the headline EPS implies.
Outlook
Management gave no guidance in the 10-Q itself. On the September 14 earnings call accompanying the filing, management indicated it expects fiscal fourth-quarter sales to be roughly flat to higher versus the $23.96 million just reported, and that its Direct Air Cooling product line should exceed $10 million for the full year.
Two forward indicators point in opposite directions, and the tension between them is the main thing to track:
Backlog rose. Orders not yet shipped were $18.6 million at July 31 versus $15.5 million at the October 31, 2025 fiscal year end, and management said on the call that backlog had reached $19.8 million by September 14.
Orders trailed shipments in the quarter. Management disclosed quarterly bookings of $22.5 million against $23.96 million of revenue — a book-to-bill ratio of 0.94x. Book-to-bill is new orders divided by shipments; below 1.0 means the company shipped more than it sold in the period. One quarter below 1.0 after a record shipping quarter is not alarming, but it does mean Q3's revenue was partly drawn from backlog built earlier, and it caps how much sequential growth is available without an order acceleration.
Our read: flat-to-modestly-up Q4 revenue is achievable on the backlog in hand, and the nine-month comparison should keep improving as the Integrated Systems drag fades — its decline narrowed from 22.4% over nine months to 6.7% in the quarter. The genuine risk is concentration and timing rather than demand: one aerospace customer was 11% of quarterly sales and 16% of receivables, a wireless provider was another 17% of receivables, and the filing is candid that these customers have "no minimum purchase obligations" and that project-based order timing is what makes Integrated Systems lumpy in the first place. The next two quarters should be judged on whether bookings recover above 1.0x and whether underlying gross margin can move above 34% without help from tariff refunds — not on the headline EPS, which is about to be distorted again, upward this time, by the valuation-allowance release.
