Coda Octopus grew fiscal Q3 revenue 9.2% to $7.72M, but the growth came entirely from lower-margin defense engineering subcontracting while its high-margin marine imaging sonar segment fell 15.2% on Middle East project delays.
Defense engineering work carried the quarter while the sonar business shrank 15%
Coda Octopus Group (Nasdaq: CODA) grew fiscal third-quarter revenue 9.2% to $7,717,469, but none of the growth came from the business the company is best known for. Its Marine Technology segment — real-time 3D underwater imaging sonar and diver display systems — fell 15.2% to $3,377,472, and the shortfall was more than covered by a 68.3% jump in the Defense Engineering Services segment, to $2,729,077. That swap is the whole story of the quarter: the same revenue line moving up, built out of a very different and structurally lower-margin mix.
The quarter covers the three months ended July 31, 2026. Coda Octopus closes its fiscal year on October 31, so this is the third quarter of fiscal 2026, not a calendar-quarter report. The 10-Q was filed on September 14, 2026.
Gross margin is the share of revenue left after the direct cost of making and delivering the product; operating margin is what's left after that plus research, selling and administrative costs, before interest and tax. "pp" means percentage points.
The mix shift is the quarter
Coda Octopus reports three segments, and they have very different economics. Marine Technology ("Products") sells and rents underwater imaging hardware and software at roughly 77–79% gross margin. Defense Engineering Services ("Services") does time-and-materials engineering subcontract work for prime defense contractors — meaning it bills hours and materials at agreed rates rather than selling a finished product — and earns around 56–59%. Precision Acoustics Limited ("PAL"), a UK acquisition still inside its three-year earn-out period, supplies acoustic sensors, materials and acoustic test tanks at 52–55%.
In the quarter just reported, the high-margin segment shrank and the two lower-margin ones grew:

That is why consolidated gross margin fell 290 basis points (2.9 percentage points) even though the Marine Technology segment's own margin improved. Management states it plainly: the decline was "primarily due to changes in the mix of revenues generated by our operating segments. In particular, the Marine Technology Business, which generally generates higher gross margins than our other operating segments, represented 43.8% of consolidated net revenues in the Current Quarter compared with 56.4% in the Previous Quarter." Nothing got structurally more expensive to build — the revenue simply came from cheaper-margin activity.
Why marine revenue fell, and why its margin went up anyway
Management attributes the Marine Technology decline to geopolitical disruption in the Middle East, specifically the conflict involving Iran and disruption to shipping near the Strait of Hormuz, which delayed offshore project activity and purchasing decisions. The figure behind that claim: revenue from Middle East and Asia customers fell to $1,231,751 from $2,130,914, a 42.2% drop. Revenue from the Americas fell a much milder 5.8%, to $1,597,751, which management ties to slower procurement on certain defense programs.
Within that shrinking segment, the composition changed sharply:
Marine Technology revenue by type
Q3 FY2026
Q3 FY2025
Change
Equipment sales
$2,257,201
$2,746,255

$321,373
$696,800
−53.9%
Total
$3,377,472
$3,984,475
−15.2%
Rental income more than doubled while outright hardware sales dropped. Renting out an existing sonar fleet carries higher margin than selling a unit, because the asset is already built and on the books — so the segment's gross margin rose to 78.5% from 77.0% even as its revenue fell. Commission expense also fell 60.5% to $37,909, because fewer sales went through agent-based distribution channels in Asia.
There is a caution inside that positive margin print. A customer renting equipment instead of buying it is a smaller, more reversible commitment, and the 59.9% fall in software sales and 53.9% fall in field services are consistent with fewer new systems being deployed. Rental revenue flattering margin is not the same as the segment recovering.
Takeaway: Revenue grew 9.2% and operating income 11.1%, but the growth came from the lowest-margin part of the group — time-and-materials defense subcontracting — while the high-margin imaging-sonar franchise shrank 15% and shifted from selling hardware toward renting it. The reported margin improvement inside Marine Technology is a mix artifact of that rental shift, not evidence the underlying demand problem in the Middle East and Asia has turned.
Costs: a $438,588 earn-out charge hid a falling wage bill
Total operating expenses rose only 2.1%, to $3,517,019, but the components moved in opposite directions.
Selling, general and administrative expense actually fell 2.9% to $2,787,803, despite absorbing a much larger acquisition-related charge. During the quarter Coda Octopus concluded that PAL would hit the second-year targets of its acquisition earn-out — the contingent payment owed to PAL's former owners if the acquired business hits agreed revenue and pre-tax profit targets, measured over three annual periods — and booked the full estimated Year 2 obligation of $438,588, against $158,872 a year earlier. (For scale: the Year 1 target was met and cost $213,343 in total, paid to the sellers after the fiscal 2025 annual report was filed on January 29, 2026.) Two offsets more than covered that $279,716 increase: wages and salaries fell 17.0% to $939,705 on reduced headcount, and foreign-exchange revaluation swung from a $237,948 expense to a $42,377 benefit, a $280,325 swing. Management is explicit that the earn-out increase "does not represent an increase in the underlying operating cost structure of the business."
The headcount reduction is not presented as a cost-saving initiative. Management attributes it to "inflationary pressures in the engineering labor market and resulting workforce instability, particularly within the Defense Engineering Services Business," which "experienced elevated staff turnover during the period," and says it is actively recruiting for vacant roles including management positions — and expects full-year fiscal 2026 wages to rise materially versus fiscal 2025. So this quarter's wage relief is attrition the company is trying to reverse, not a permanent cost base reset.
Research and development rose 27.4% to $729,216, concentrated in a cross-group engineering effort to bring a PAL product line in-house that had previously depended on outside suppliers (PAL R&D +57.9% to $155,494; Marine Technology R&D +10.7% to $473,749 as its engineers were deployed on that project). Defense segment R&D rose 117.5% to $99,973, spent on the Thermite Octal mission-computing product family.
Currency was close to a non-event this quarter. Translating the foreign subsidiaries at prior-year exchange rates would have produced $26,608 more revenue and $29,408 more cost — a net $2,800 swing on operating profit. The 9.2% revenue growth is not an FX effect.
Below the operating line
Other income rose 57.6% to $258,076, of which $233,817 was interest earned on the company's deposit accounts (up from $154,848) and $44,249 was a one-time interest payment from tax authorities on a delayed Employee Retention Credit refund. With $31.7 million of cash on a $68.9 million balance sheet, interest income is now a recurring and material earnings contributor — but note that roughly $44,000 of this quarter's other income will not repeat.
Tax is why 16.0% pre-tax growth became only 8.3% net income growth. The effective tax rate — tax as a share of pre-tax profit — rose to 22.4% from 16.9%, which the company attributes to higher taxable income and the geographic mix of where that income was earned across its US, UK and Danish entities. Management also flags that changes to the US GILTI regime under the One Big Beautiful Bill Act take effect for the company in fiscal 2027, a known future variable in the tax line rather than a current-period item.

The nine-month picture is the same trade made at larger scale, and it flatters the company more than the quarter does. Defense Engineering Services revenue rose 38.5% to $7,039,023 (driven by the UK operation), PAL rose 16.0% to $4,720,503 on more acoustic test environment sales, and Marine Technology fell 5.6% to $9,572,067. Because operating expenses were essentially flat (+0.4%) against 10.6% revenue growth, almost all the incremental gross profit dropped through to operating income, which rose 38.6%. Marine Technology's nine-month gross margin improved to 76.9% from 72.6% on the same rental-mix effect — rental revenue for the nine months was $2,212,222 against $697,851, up 217.0%, while equipment sales fell 19.3%.
Cash conversion is the soft spot
The balance sheet is unusually clean for a company this size: $31,714,519 of cash, $49,174,243 of working capital (current assets minus current bills due within a year), $62,730,812 of stockholders' equity against just $6,122,554 of total liabilities, and nothing drawn on its $4 million HSBC revolving credit line. Accumulated earnings crossed into positive territory at $741,584, from a $(3,276,561) deficit at the October 31, 2025 year end.
Cash generation, however, moved the wrong way. Nine-month operating cash flow fell to $3,430,017 from $4,307,865 a year earlier, despite net income rising $913,423. The reconciliation explains it: accounts receivable consumed $1,824,944 of cash this year versus $224,619 last year, and accounts payable and other current liabilities drained a further $826,831 (versus a $62,264 source last year). Receivables on the balance sheet stand at $5,620,208 against $3,732,806 at fiscal year end, up 50.6%, with unbilled receivables — work performed but not yet invoiced — up to $3,260,065. That is the working-capital signature of growth concentrated in time-and-materials defense subcontracting, which bills and collects more slowly than shipping a sonar unit. Cash taxes paid also rose to $1,132,783 from $415,221.
Capital spending was modest at $365,727 for the nine months (down from $805,380), and the company sold a vessel for $148,208, booking a $133,566 gain inside other income.
Outlook
Coda Octopus gives no revenue or earnings guidance, so what follows is what management flagged plus our own read.
What management said: it expects Middle East geopolitical conditions and related economic uncertainty to continue affecting results "during the remainder of fiscal 2026"; it expects full-year fiscal 2026 wages and salaries to rise materially over fiscal 2025 as it fills vacancies; it expects marketing spend roughly flat year over year; and it believes cash on hand plus the undrawn revolver covers the next twelve months. Management also states it does not believe the Middle East demand drop is "indicative of a structural change in the market."
Our read: with one quarter left in fiscal 2026 (ending October 31, 2026), the shape of the year is largely set — nine-month EPS of $0.36 against $0.27 already banks most of the improvement. The risks to fiscal 2027 are specific rather than macro. First, the margin arithmetic: if Defense Engineering Services keeps growing at 38–68% while Marine Technology stays soft, consolidated gross margin keeps drifting down, and revenue growth converts to profit growth at a progressively worse rate. Second, the wage line reverses: this quarter's 17% wage decline came from turnover the company wants to undo, so the Q3 cost base is probably the low point, not the run rate. Third, the defense concentration cuts both ways — that segment's revenue comes from a limited number of prime contractors whose awards depend on government appropriations, so the same concentration producing 68% growth this quarter can produce an equally abrupt gap if a program funding decision slips.
The offsetting case is that nothing in the marine decline looks impaired: the segment's gross margin went up, the rental fleet is being utilized harder, and the lost revenue is delayed procurement in specific regions rather than lost share. A debt-free balance sheet with $31.7 million of cash against a $68.9 million asset base means the company can absorb several more quarters of this without financial strain. The number to watch in the Q4 and full-year filing is whether Marine Technology equipment sales — not rentals — turn back up, and whether receivables stop outrunning revenue.
