Airgain (AIRG) Q3 2026 earnings review
Airgain's industrial modem sales jump, but vehicle gateways decline
Airgain, a maker of wireless modems and antennas, is growing on industrial demand while its consumer and vehicle lines shrink. Third-quarter sales rose 9% from a year ago as enterprise modem shipments jumped, offsetting a one-third drop in consumer router antennas caused by memory chip shortages. Chief executive Jacob Suen set a fourth-quarter sales plan of $16.5 million at the middle of the range, but lower-margin modems pushed gross margin down and kept Adjusted EBITDA below the third-quarter plan.
| Sales | $15.3M +9.3% from a year ago |
|---|---|
| Enterprise sales | $10.0M +48% from last quarter |
| Gross margin, excluding one-offs | 42.4% -2.0 percentage points from a year ago |
| Q4 sales outlook | $15.5–17.5M middle of the range: +36% from a year ago |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because strong enterprise modem demand cleared one major risk while vehicle gateway and margin setbacks reinforced another. The higher fourth-quarter sales outlook proves enterprise demand will not fall off a cliff after a $4 million order finished shipping in the third quarter, and adds two AI data center contracts for 2027. The bad news: automotive revenue fell 17% from last quarter on lower vehicle gateway shipments, contradicting the fleet ramp thesis, while gross margin is planned down again to 41.5% excluding one-offs.
The question now is whether Airgain is transitioning into a higher-margin wireless systems company or remaining a lower-margin modem supplier that funds working capital through stock sales. If fleet gateways and 5G signal nodes begin shipping in volume, automotive sales and gross margins will rebound; if only modems grow, margins will stay near 41%. Fourth-quarter automotive sales and gross margin will tell.
🐂 Bull Case
Enterprise Modem Demand Cleared the Fourth-Quarter Order Hurdle
Airgain sells NimbeLink embedded cellular modems, which are small radio modules built into industrial machines. Chief executive Jacob Suen said third-quarter growth was "driven by continued momentum in our enterprise IoT business" and pointed to "new opportunities in areas such as AI data center infrastructure". A $4 million customer order was due to finish shipping in the third quarter, creating a risk that enterprise sales would drop in the fourth.
Instead, enterprise revenue jumped and the fourth-quarter outlook climbed higher. The wireless hardware maker also won two contracts to put NimbeLink modems into AI data center power monitors and server racks, "with initial revenue expected in 2027".
- Enterprise revenue: $10.0 million, up 48.2% from last quarter and up 45.2% from a year ago
- Enterprise share of total sales: 65.1%, up from 49.1% last quarter by our math
- Fourth-quarter total sales outlook: $15.5 million to $17.5 million, up 7.7% at the middle of the range
This matters because the fourth-quarter sales plan rises $1.2 million at the middle of the range even after the $4 million order finishes, which clears the near-term order cliff.
What to watch: fourth-quarter enterprise revenue in next quarter's release. Holding near $10 million will confirm that ongoing industrial and robotics orders have replaced the completed contract.
Tight Cost Control Lifted Profit Despite Product Mix
Airgain has cut staff and overhead over the past year so that rising sales would turn into profit. It also continues to test new products with carrier partners, demonstrating its Lighthouse 5G Intelligent Node, a cellular signal booster, at 140 megabits per second in a California neighborhood "where usable cellular data service was previously unavailable", and showing its AirgainConnect vehicle routers at a FirstNet public-safety summit.
In the third quarter, GAAP operating expenses — research, sales and general overhead — fell to 44.8% of revenue from 50.5% a year ago, a drop of 5.7 percentage points by our math. Excluding one-offs, operating expenses stayed flat at $6.0 million while sales rose $1.6 million from last quarter. Adjusted EBITDA, which is operating cash profit before interest, taxes, depreciation and stock compensation, rose to $0.57 million from $0.38 million last quarter, though it missed the $0.70 million plan because lower-margin modems reduced gross margin.
What to watch: fourth-quarter Adjusted EBITDA against the $0.8 million plan. Hitting that target while gross margin steps down again will show that volume growth outpaces the planned $0.2 million rise in operating costs.
🐻 Bear Case
Vehicle Gateway Shipments Fell Despite Reported Design Wins
Airgain's automotive segment houses aftermarket antennas and AirgainConnect, its roof-mounted 5G gateway for police cars, utility trucks and other fleets. Supporters view the growing trial pipeline and recent fleet contract wins as the main growth driver for the business, while skeptics argue that recurring delays keep pushing actual revenue further out. On page one of the release, chief executive Jacob Suen said the team is making progress across AirgainConnect.
The segment table tells the opposite story. Automotive revenue fell 17.5% from last quarter to $0.96 million, down from $1.17 million in the second quarter. Airgain said the sequential drop was driven by "lower aftermarket antenna and vehicle gateway shipments". Compared with a year ago, automotive revenue rose 96.7%, but only because last year's third quarter had collapsed to $0.49 million.
This matters because the five fleet contracts won last quarter and the Nextivity product acquisition were supposed to lift gateway shipments in the second half. Instead, vehicle gateway shipments declined sequentially.
What to watch: fourth-quarter automotive sales and whether Airgain closes its targeted large first-responder fleet contract by year-end. Another sub-$1 million quarter would show that fleet trials are still not turning into volume shipments.
Memory Chip Shortages Cut High-Margin Consumer Sales
In the consumer market, Airgain designs custom Wi-Fi antennas built inside home internet routers for cable and mobile operators. Those antennas carry higher gross margins than enterprise modems, so consumer volume heavily shapes company profitability. In the release, the San Diego group warned of component shortages, particularly "memory semiconductors which suppliers may redirect toward higher-margin AI applications".
Because router makers could not get enough memory chips, consumer sales fell 24.4% from last quarter and 34.1% from a year ago to $4.39 million. That drop pushed the cost of making products up by 1.8 percentage points of revenue from a year ago, to 58.2%.
- Consumer share of sales: 28.6%, down from 42.3% last quarter and 47.5% a year ago by our math
- GAAP gross margin: 41.8%, down 1.8 percentage points from a year ago
- Gross margin excluding one-offs: 42.4%, down 2.0 percentage points from a year ago, with 41.5% planned for Q4
The company blamed the margin drop on "higher sales of lower-margin enterprise IoT products and reduced sales of higher-margin consumer products". Because the fourth-quarter outlook lowers gross margin another 0.9 percentage points at the middle of the range, the consumer shortage is getting worse rather than clearing.
What to watch: fourth-quarter gross margin excluding one-offs against the 40.0% to 43.0% range. A reading near 40% would show that consumer antenna shipments fell again.
Operating Cash Outflow Continued and Share Count Rose
Airgain has reported positive Adjusted EBITDA for two quarters in a row, but its operations still consume cash and still lose money on a GAAP basis. Through the first nine months of 2026, operations used $2.70 million in cash, which by our math means about $0.15 million flowed out in the third quarter alone as inventories rose to $4.94 million and payments to suppliers reduced accounts payable by $2.43 million year to date.
To keep cash at $7.71 million, management raised $1.84 million over nine months by selling new stock through its at-the-market offering program, including $0.24 million this quarter by our math, plus $1.40 million from employee stock plans. What to watch: fourth-quarter operating cash flow and share count, because further inventory buildup would force more stock sales that dilute existing shareholders.
Risks this quarter didn't answer
Several standing concerns and scheduled third-quarter milestones cannot be read from the earnings release alone and await the conference call or quarterly filing.
- AirgainConnect and Lighthouse revenue: still omitted after nine quarters; any dollar figure in the filing would test the platform transition.
- Quarterly fleet design-win count: after reporting five wins last quarter, the release gives no count; the conference call remarks will show if conversion slowed.
- Acquired Nextivity revenue split: the release does not separate acquired gateway sales from underlying sales; the filing's acquisition note will show it.
- Third-quarter product milestones: the release does not state whether Coco Robotics, drone production units, T-Mobile Lighthouse samples or international 4G/5G combo samples shipped on schedule.
- Customer concentration: three accounts held 43% of sales last quarter; the filing's footnote will show how much of the $10.0 million enterprise quarter came from one buyer.
👓 Other Themes
Airgain Launches AI Antenna Design Tool and Adds Board Member
During the third quarter, the wireless hardware provider introduced Airgain RF Intelligence, an artificial-intelligence software platform designed to "accelerate antenna design and unlock new market opportunities" for its existing antenna lines. Separately, the board of directors appointed wireless industry veteran Stephan Memmen as a new director. Neither announcement carries near-term revenue or expense targets in the release.
💲 Other KPIs
Stockpiled goods and parts rose 38.1% from $3.58 million at the end of 2025, and climbed 18.1% from $4.19 million last quarter by our math. Inventories have grown for three straight quarters to support rising enterprise modem shipments, tying up $1.36 million of cash over the first nine months of the year.
Short-term obligations outside supplier bills and payroll more than doubled from $1.79 million at the end of December, an increase of $2.82 million. Last quarter's filing showed a $1.03 million customer advance payment inside this line, and the further jump this quarter helped offset cash tied up in inventory and supplier payments.
Weighted average diluted shares used for profit excluding one-offs rose 11.9% from 11.94 million a year ago, and increased 1.3% from 13.19 million last quarter. The wireless group issued shares through its at-the-market stock offering and employee equity plans, and the fourth-quarter outlook assumes 13.4 million diluted shares.
🔮 Guidance
New. The plan calls for $16.5 million at the middle of the range, which by our math is up 7.7% from the third quarter and up 36.1% from a weak $12.1 million fourth quarter last year. Airgain has met or beaten the middle of its quarterly sales plan in three of the last four quarters.
New. The middle of the range is 40.7%, down 1.1 percentage points from 41.8% in the third quarter and down 4.1 percentage points from 44.8% a year ago. The lower target reflects a continued mix shift toward enterprise modems while consumer antennas face chip shortages.
New. The plan points to 41.5% at the middle of the range, down 0.9 percentage points from 42.4% this quarter and down 4.8 percentage points from 46.3% a year ago. It is the third consecutive quarter in which the wireless maker has set its margin outlook lower than the quarter before.
New. The company expects GAAP operating expenses to rise by about $0.13 million from $6.87 million in the third quarter. The plan includes $0.7 million of stock-based compensation and $0.1 million of intangible amortization.
New. Management plans for operating expenses excluding one-offs to step up by $0.2 million from $6.0 million in the third quarter. Because sales are planned to grow faster than expenses, the cost ratio at the middle of the sales range drops to 37.6% from 39.1% this quarter by our math.
New. The plan has the GAAP loss narrowing to 2 cents per share, or about $0.3 million on 13.2 million basic shares, from 4 cents per share in the third quarter and 20 cents a year ago. Airgain missed its GAAP loss per share target in each of the last two quarters.
New. The outlook calls for 5 cents per share, or $0.7 million on 13.4 million diluted shares, up from 4 cents in the third quarter and a loss of 3 cents a year ago.
New. The plan targets $0.8 million, up 40.4% from $0.57 million in the third quarter and swinging from a loss of $0.19 million in the fourth quarter of last year.
❓ Key Questions
Why did vehicle gateway shipments drop in the third quarter?
Airgain closed five fleet contracts in the second quarter and acquired Nextivity's product line early this year, yet automotive revenue fell 17.5% from last quarter on lower vehicle gateway shipments. Investors need to know how many AirgainConnect units shipped and what caused the drop.
What drove the $2.8 million jump in accrued liabilities?
Accrued liabilities and other climbed from $1.79 million in December to $4.61 million in September, funding working capital while inventories rose. Management has not explained in the release whether this increase comes from new customer advance deposits or unpaid expenses.
Did the robotics, drone and T-Mobile sample milestones ship?
Last quarter, management scheduled third-quarter production shipments for Coco Robotics and a drone customer, plus pre-production samples for a T-Mobile Lighthouse unit. The release mentions none of these four deadlines.
How concentrated was the $10.0 million enterprise quarter?
Enterprise revenue jumped $3.24 million from last quarter as a $4 million purchase order neared completion. Without the customer breakdown or backlog figure, investors cannot tell how much fourth-quarter demand rests on a single buyer.
