Astronics (ATRO) Q3 2026 earnings review
Astronics profit margins pass target, but Army radio ramp slips
Astronics, a maker of aircraft cabin electronics, power systems and military test gear, lifted its profit margins above its high-teens target even as it predicted a quieter fourth quarter. Sales rose 28% from a year ago to a record $272 million, pushing operating margin excluding one-offs to 19% (or 18% by our math without tariff refunds). Chief executive Peter Gundermann held the full-year sales plan steady and forecast $255–275 million for the fourth quarter, a slight dip from the third quarter's record level.
| Revenue | $271.7M +28.5% from a year ago |
|---|---|
| Operating margin, excluding one-offs | 18.8% 12.3% a year ago (18.1% without tariff refund) |
| Aerospace backlog | $670.0M 1.05 ratio of orders to sales |
| Full-year revenue outlook | Unchanged $1.02–1.04B (middle of the range: +19.5%) |
⚖️ Verdict: 🟢 Bullish
The story got better because factory volume in the main aircraft division carried margins past management's target while aircraft orders rebounded and the Seattle facility consolidation finished, letting the company cut its capital spending plan by a third. One caution: the smaller Test Systems division took another $2 million charge on older rail contracts and pushed full-rate production on its US Army radio test program out by one quarter to early 2027.
The question now is whether operating margins can stay near 18% as quarterly sales growth slows against tougher comparisons and pricing catch-up winds down. If factory efficiency and the Army radio ramp hold, margins will climb further in 2027; if airline spare-parts orders cool or rail write-downs repeat, profit margins will plateau. Next quarter's formal 2027 outlook and Test Systems margin will tell.
🐂 Bull Case
Higher Volume Lifted Operating Margin Above Target
"We delivered a strong third quarter, with record sales and operating income and an adjusted EBITDA margin near its all-time high," chief executive Peter Gundermann said. Astronics has long aimed for operating margins in the high teens when excluding one-offs, and third-quarter volume pushed the business past that mark.
- Operating margin excluding one-offs: 18.8%, up 6.5 percentage points from a year ago
- Operating margin excluding both one-offs and $1.9 million of tariff refunds: 18.1% by our math
- Cost of making products: 65.4% of sales, down 4.1 percentage points from a year ago
- Research and development: 3.4% of sales, down 1.4 percentage points
- Selling and overhead costs: 11.3% of sales, or 13.3% by our math without $5.3 million in legal recoveries
The gain matters because it came from factory output rather than accounting help. Even after stripping out the tariff refund and the $4.4 million UK patent repayment, higher production across aircraft and test lines carried profit above management's goal.
What to watch: fourth-quarter operating margin excluding one-offs and tariff refunds. Holding near 18% on slightly lower quarterly sales would show the factory gains are permanent.
Aircraft Orders Pushed Aerospace Backlog to a Record
In the second quarter, a single military radio order carried Astronics' order book while aircraft orders slowed. This quarter the main Aerospace division — which makes cabin power, lighting and flight hardware — took the lead back and lifted its unfilled order backlog to a record $670 million.
Aerospace customers placed $258.3 million in new orders, up 34.6% from a year ago by our math, leaving the division with $1.05 of new orders for every dollar billed. That kept its ratio of orders to sales above one for a fifth straight quarter and added $12.8 million to the division's backlog. Company-wide backlog held steady at $780 million, up 19.0% from a year ago by our math after stripping out the $10.6 million backlog acquired with Bühler Motor Aviation at close.
What to watch: the ratio of Aerospace orders to sales in the fourth quarter. A sixth reading above 1.0 would support Gundermann's view of double-digit sales growth in 2027.
Seat Motion and Electrical Power Lead Cabin Growth
Astronics reorganized its aircraft product lines at the start of 2026 to highlight cabin hardware and electrical power systems. Both newer categories grew faster than the rest of the aircraft division in the third quarter, while the core cabin electronics line also expanded.
- Seat Motion (motors and actuators for airline seats): $24.9 million, up 112.3% from a year ago
- Flight Critical Electrical Power (power generation and distribution for aircraft): $20.9 million, up 24.9%
- Inflight Entertainment & Connectivity (IFEC, cabin Wi-Fi and seat power): $131.0 million, up 23.9%
- General Aviation (private and business jets): $21.1 million, up 51.7% on higher IFEC demand
Seat Motion's jump includes Bühler Motor Aviation, acquired in October 2025, which contributed $5.9 million last quarter, so about half of that line's dollar gain came from the deal. Even so, the underlying growth across seat hardware, airframe power and cabin electronics shows airlines and private jet builders are upgrading cabins across all three lines at once.
What to watch: Seat Motion sales growth in the fourth quarter. Because the Bühler Motor Aviation deal closed on October 13, 2025, next quarter will show the line's underlying growth rate without acquisition help.
Seattle Facility Consolidation Completed and CapEx Cut
Heavy capital spending to combine factories and catch up on deferred maintenance has been a persistent drag on Astronics' cash generation for a year. This quarter the company finished its main project and lowered its full-year spending plan by a third.
Astronics said its spending covered "the now completed consolidation of operations and capacity expansion in a new Seattle facility" during the third quarter, after the finish date had slipped from the second quarter. With the project done, capital spending fell to $4.2 million, or 1.5% of sales by our math, down from $11.2 million in the first quarter and $5.7 million in the second. Management cut its 2026 capital spending plan from $40–45 million to $25–30 million, and also collected a "refund of approximately $4.4 million in damages and associated legal fees" after winning its UK patent appeal.
What to watch: the initial 2027 capital spending outlook next quarter. A lower run rate now that Seattle is finished will show how much operating cash turns into free cash flow.
🐻 Bear Case
Army Radio Ramp Slipped as Transit Charges Returned
Test Systems — the smaller division that builds test equipment for the military and transit agencies — is supposed to be Astronics' next profit driver as it ramps the US Army's TS-4549/T radio test program. Last quarter Gundermann said the program would reach full-rate production exiting the fourth quarter, and the division had gone three quarters without cost overruns on its older rail contracts.
Both parts of that story took a step back in the third quarter. The radio test program generated $5.3 million in sales, and Astronics now expects it to reach "full rate production in the first quarter of 2027", a one-quarter delay. At the same time, the division took a $2.2 million "revision of estimated costs to complete certain long-term mass transit contracts which reduced revenue recognized in the period".
Without that $2.2 million charge, Test Systems sales would have risen 51.7% instead of 40.0%, and its operating margin excluding one-offs would have been 22.4% instead of 15.9% by our math. The profit improvement on the Army radio work is real, but the recurring rail write-downs and the slower ramp show execution in Test Systems remains uneven.
What to watch: Test Systems operating margin and any further mass transit contract revisions in the fourth quarter. Another charge or a further delay past the first quarter of 2027 would cap the division's recovery.
Fourth Quarter Plan Points to Slower Growth
Three months ago, Astronics told investors that fourth-quarter sales would improve modestly over the third quarter. After delivering $271.7 million in the third quarter, the aerospace supplier kept its full-year target unchanged and set its fourth-quarter outlook at $255–275 million.
"While fourth quarter sales may be modestly lighter than the third quarter record level, our preliminary outlook for 2027 suggests another year of strong double digit growth," Gundermann said. At the $265 million middle of the range, fourth-quarter sales would fall 2.5% from the third quarter and grow 10.4% from a year ago by our math, down from 28.5% growth this quarter. Part of the slowdown comes from comparing against last year's record $240.1 million fourth quarter, which included a surge in spare-parts shipments, but the sequential dip also shows quarterly output is leveling off near $270 million until new programs ramp in 2027.
What to watch: the formal 2027 revenue outlook next quarter. It will show whether the fourth-quarter dip is just year-end timing or a flatter growth rate.
Convertible Notes Added 3.7 Million Shares
Astronics refinanced its debt in late 2025 using convertible notes — bonds that turn into stock or require extra share payouts when the company's equity value rises past set thresholds. Those bond terms are now enlarging the share count used to calculate profit per share.
The company's weighted average diluted share count rose 14.2% from a year ago to 48.5 million shares by our math, up from 46.5 million in the second quarter. Footnotes show the third-quarter count includes 1.904 million assumed shares from the premium on its 0% convertible notes due 2031 (up from 1.643 million for the nine-month average) and 1.750 million assumed shares from its remaining 5.5% convertible notes. A separate hedging contract called a capped call prevents actual share dilution on the 0% notes until the stock exceeds $68.44 per share, but accounting rules already count the shares and any early bond conversions would require cash to repay principal.
What to watch: the diluted share count and any convertible note settlement disclosures in the quarterly filing. Rising assumed shares reduce the share of operating profit that reaches each stockholder.
Risks this quarter didn't answer
Three standing business risks received no updated figures in the third-quarter earnings release.
- MV-75 future vertical lift military aircraft program: no update on 2026 revenue (lowered to about $35 million last quarter) or the prime contractor's funding schedule; the conference call or quarterly filing may address it.
- Satellite connectivity transition: no update on the roughly $60 million geostationary satellite business facing airline shifts to low-earth-orbit systems; call commentary will be needed.
- Commercial aircraft build rates: no breakdown of customer concentration (Boeing was 12% of sales last quarter); the quarterly filing's footnote on major customers will provide the reading.
👓 Other Themes
Tariff Refunds Help Margins While Future Receipts Shrink
Astronics recorded $1.9 million in tariff refunds inside its Aerospace division during the third quarter, following a $2.0 million refund in the second quarter. Management now estimates future tariff refunds under the International Emergency Economic Powers Act (IEEPA) will total $5–6 million, down from last quarter's $6–8 million estimate because of the money just collected, though the company still cannot confirm when the remaining cash will arrive.
💲 Other KPIs
Astronics cut its long-term debt by $25.6 million from the second quarter and by $49.7 million since the end of 2025. The lower debt balance and lower interest rates from last September's refinancing reduced net interest expense by 37.1% from a year ago to $1.8 million, leaving $278.0 million in available liquidity.
Cash generated from operations was $25.8 million, down from $30.1 million in the second quarter and $34.2 million a year ago. With $4.2 million of capital spending, free cash flow was $21.6 million by our math. Uncollected customer bills (accounts receivable) rose 36.2% from a year ago to $257.0 million, growing faster than sales as the US manufacturer stocked inventory for 2027.
🔮 Guidance
Unchanged. The plan still calls for 19.5% sales growth at the $1.03 billion middle of the range, following two raises earlier in the year (+$15M in the first quarter, +$45M in the second). By our math, the full-year midpoint leaves $267.7 million for the fourth quarter, or 11.5% growth from a year ago.
Cut. Management previously expected fourth-quarter sales to improve modestly over the third quarter, but the $265 million middle of the new range is 2.5% below the third quarter's $271.7 million record. The range represents 10.4% growth from a year ago against a high fourth-quarter 2025 base. Over the last four quarters Astronics beat its quarterly midpoint by 3.1% on average; if the pattern holds, fourth-quarter sales would reach $273.3 million by our math.
Cut. The aerospace group lowered its full-year capital spending plan by $15 million at the middle of the range now that the Seattle factory consolidation is complete. With $21.1 million spent in the first nine months, the outlook leaves about $6.4 million of spending for the fourth quarter by our math.
Lowered. Following the $1.9 million tariff refund recognized in the third quarter, the US company now estimates $5–6 million in remaining future refunds, and noted that the timing of receipts cannot be confirmed.
❓ Key Questions
What caused the $2.2 million mass transit cost revision?
Test Systems had gone since early 2025 without a charge on its legacy rail contracts. Investors need to know which contract drove the $2.2 million revenue reduction and how much uncompleted mass transit backlog remains at risk.
Why did Army radio full-rate production move to Q1 2027?
Last quarter management expected the TS-4549/T program to reach full-rate production exiting the fourth quarter of 2026. The release now says the first quarter of 2027, raising the question of whether customer testing or supply chain timing caused the slip.
What is Seat Motion's underlying growth without Bühler Motor Aviation?
Seat Motion sales more than doubled to $24.9 million, but the press release did not state how much of third-quarter revenue came from the October 2025 acquisition of Bühler Motor Aviation versus existing programs.
Where do MV-75 revenue and geostationary satellite sales stand?
The release gave no figures for the MV-75 military aircraft development program or the roughly $60 million geostationary satellite connectivity business facing airline upgrades to low-earth-orbit constellations.
