Ducommun (DCO) Q3 2026 earnings review
Ducommun's defense orders double shipments, but overhead holds profit back
Ducommun, a maker of aircraft and missile parts, booked record military orders while commercial plane shipments carried its third-quarter sales. Revenue grew 6% to $227 million, beating the low-to-mid single-digit second-half pace chief executive Stephen G. Oswald pointed to last quarter, as a 28% jump in commercial aerospace covered a dip in defense shipments. Factory closures and pricing lifted gross margin to a record, but higher corporate overhead and stock pay ate up the gain and left profit per share excluding one-offs slightly lower.
| Revenue | $227.0M +5.9% from a year ago |
|---|---|
| Gross margin | 28.9% +1.4 percentage points from a year ago |
| Profit per share, excluding one-offs | $1.21 -1% from $1.22 a year ago |
| Remaining performance obligations (order book) | $1.29B +25% from a year ago; defense book-to-bill at 2.2x |
⚖️ Verdict: 🟢 Bullish
The story got better because military customers booked more than twice what Ducommun shipped, lifting its unfilled order book 25% from a year ago to $1.29 billion. That order wave backs up management's promise of a 2027 defense ramp and shows the second-half revenue slowdown is about delivery timing rather than weak demand. One caution: corporate overhead rose faster than sales, preventing record factory margins from reaching the bottom line.
The question now is whether the swelling military order book will lift operating margins when those parts ship in 2027. If the new orders carry proprietary content and overhead stabilizes, earnings will climb with volume; if they lean toward lower-margin missile cables and Structural Systems mix stays weak, profit growth will lag sales. Fourth-quarter operating margins and the 12-month order conversion rate in the quarterly filing will tell.
🐂 Bull Case
Defense Orders Doubled Quarterly Shipments
Ducommun makes electronic and structural parts for military aircraft, missiles and commercial planes. While military shipments dipped this quarter, new defense orders reached $263.5 million, or 2.2 times the defense revenue it recorded. Chief executive Stephen G. Oswald said the order book is "setting the stage for strong multi-year growth" across the defense business in 2027.
- Total remaining performance obligations (RPO, the value of firm, unfilled customer orders): $1.29 billion, up 24.7% from a year ago by our math
- Net new defense RPO added this quarter: $144.9 million by our math
- Company-wide book-to-bill ratio (new orders divided by revenue): 1.6x
This surge in orders matters because it eases doubts about why management forecast slower growth for the second half of 2026. The company is adding firm military contracts much faster than it ships parts, which builds a larger revenue cushion for 2027.
What to watch: the quarterly filing's note on what share of the $1.29 billion order book converts to revenue within 12 months. A stable conversion rate around 70% would confirm these new military orders will lift revenue next year rather than sitting in later years.
Commercial Aircraft Recovery Offset the Defense Dip
For the past year, aircraft builders held back orders to burn through extra parts in their warehouses. This quarter, Ducommun's commercial aerospace sales rose 27.7% from a year ago to $97.2 million, led by parts for Boeing 737 MAX and Airbus A320 single-aisle jets. Oswald called the jump "wonderful news and now nearing a $100 million quarterly run rate" for the commercial business.
That $21.1 million jump in commercial sales more than covered the $9.2 million drop in military sales, lifting total revenue 5.9% to $227.0 million. That beat the 2% to 5% second-half growth pace management pointed to last quarter. However, commercial customers booked only $81.7 million in new orders, or 0.8 times shipments, so the commercial order book shrank by $15.5 million by our math.
What to watch: the commercial aerospace book-to-bill ratio in the fourth quarter. A rebound above 1.0x would show that inventory clearing at Boeing and Spirit AeroSystems is finishing on schedule by year-end.
Factory Closures Lifted Gross Margin to a Record
Ducommun closed two older plants in California and Arkansas last year and moved their production lines to low-cost facilities. That shift, combined with higher factory volume and "facility consolidation synergy realization and strategic pricing", lifted gross margin by 1.4 percentage points from a year ago to a record 28.9%.
Electronic Systems, the division that makes radar, missile and aircraft circuit cards and wiring harnesses, drove the gain. Its operating margin excluding one-offs climbed 3.6 percentage points from a year ago to 22.5% on higher output. That helped lift company-wide Adjusted EBITDA (earnings before interest, taxes, depreciation, amortization and one-offs) to 17.5% of revenue, within half a point of its 2027 target.
What to watch: gross margin in the fourth quarter as missile cable production scales up. Keeping gross margin above 28% would prove that factory savings can offset a higher mix of build-to-print contract manufacturing.
🐻 Bear Case
Overhead Costs Ate Up the Factory Margin Gains
"Gross margin expansion is an important story for DCO and its investors," Oswald said, highlighting the 1.4 percentage point jump in factory profitability. The company wants investors to focus on gross margin and Adjusted EBITDA, which excludes stock-based pay and pension charges.
Below the factory line, higher overhead erased the entire gross margin gain. Selling, general and administrative expenses (advertising, management pay and corporate overhead) rose by $5.8 million, climbing 1.7 percentage points of revenue to 17.5%. Corporate pay, benefits and legal fees rose, and stock-based compensation jumped 36.6% by our math to $5.6 million.
- Gross margin: 28.9%, up 1.4 percentage points from a year ago
- Selling, general and administrative expenses: 17.5% of revenue, up 1.7 percentage points
- Operating margin excluding one-offs: 12.3%, down 0.4 percentage points from 12.7% a year ago
- Profit per share excluding one-offs: $1.21, down from $1.22 a year ago
Because overhead grew faster than gross profit, operating profit excluding one-offs rose only 3.1% on 5.9% revenue growth. A higher share count and interest bill then left profit per share excluding one-offs down 1%.
What to watch: corporate general and administrative expenses as a share of revenue next quarter. A drop back below 6% of revenue would show that this quarter's pay and professional fee increases were temporary.
Defense Shipments Shrank and Structural Margins Slipped
While military orders surged, actual military and space revenue fell 7.2% from a year ago to $118.6 million. Oswald attributed the drop to "temporal weakness due to timing of orders and production on ground vehicles, Blackhawk and Apache rotary-wing aircraft platforms, and select radar programs" during the quarter.
Meanwhile, Structural Systems — the division that builds metal and composite body parts for aircraft and missiles — grew revenue 9.3% to $97.4 million, but its profit shrank. Its operating margin excluding one-offs fell 2.2 percentage points from a year ago to 14.2%, which the company blamed on an unfavorable mix of products.
What to watch: Structural Systems operating margin excluding one-offs in the fourth quarter. A recovery above 16% would show the mix shift was a one-quarter blip rather than pricing pressure on rising commercial aircraft shipments.
Risks this quarter didn't answer
Four standing concerns from prior quarters got no new numbers in the earnings release, because the detailed tables live in the quarterly filing or conference call remarks.
- Missile revenue growth rate and dollar size: the release noted growth in Tomahawk, MIR and TOW missiles, but gave no growth percentage after reporting 68% growth last quarter.
- Acquisition plans: management teased September news last quarter, and while it held its Investor Day on September 17, the release announced no acquisition.
- Fixed-price contract cost overruns: unfavorable catch-up adjustments reached $5.4 million in the first half; the third-quarter figure will appear in the quarterly filing.
- Internal control remediation and customer or tariff concentration: any updates following the May restatement will appear in the quarterly filing.
👓 Other Themes
Management Set Targets for 2032
On September 17, Ducommun unveiled its VISION 2032 plan in New York, "with an annual revenue target of $1.6 to $1.7 billion, engineered product mix of 40%, aftermarket mix of 20%, and Adjusted EBITDA margin of 23%", Oswald said. Engineered products are proprietary parts Ducommun owns the design for, which sat at 23% of sales last year against a prior 25% goal for 2027.
💲 Other KPIs
Cash generation improved sharply, allowing Ducommun to pay down debt for a second straight quarter. Operating cash flow rose to $32.7 million from $18.1 million a year ago. After $5.6 million in capital spending, free cash flow reached $27.1 million by our math, cutting total debt by $26.2 million from last quarter to $250.2 million.
Customer advance payments doubled over the past nine months. Contract liabilities — cash customers pay upfront before Ducommun builds and ships the parts — rose to $81.6 million from $56.4 million last quarter and $40.7 million at the end of 2025. These upfront defense deposits funded much of the quarter's cash flow.
The share count crept higher from stock-based employee pay. Weighted-average diluted shares used for profit excluding one-offs rose 1.3% from a year ago to 15.56 million, up from 15.36 million in the third quarter of 2025, as the aerospace supplier directs its cash toward paying down debt rather than buying back stock.
🔮 Guidance
Unchanged. The aerospace supplier reiterated its target for Adjusted EBITDA to reach 18.0% of revenue by the end of 2027. After delivering 17.5% this quarter and 17.2% over the first nine months of 2026, the company sits 0.5 percentage points away from its goal with five quarters remaining.
❓ Key Questions
Why did overhead expenses outpace gross profit growth?
Selling, general and administrative costs rose $5.8 million from a year ago, eating up the 1.4-point gross margin gain and leaving profit per share excluding one-offs down 1%. Investors need to know how much of this corporate cost step-up is permanent.
How fast did the missile franchise grow in Q3?
Last quarter management highlighted 68% growth in missiles, but the third-quarter release named only Tomahawk, MIR and TOW without a growth rate or dollar figure. Consistent sizing is needed to track the main driver of the 2027 defense ramp.
What caused the 2.2-point margin drop in Structural Systems?
Structural Systems grew sales 9.3% on rising commercial aircraft builds, yet its operating margin excluding one-offs fell from 16.4% to 14.2% on unfavorable product mix. Management should clarify which aircraft programs diluted the division's profitability.
How much of the $1.29 billion order book ships in 2027?
Military bookings hit 2.2 times shipments while military revenue fell 7.2%. Knowing whether 70% of remaining performance obligations still convert within 12 months will show if these orders lift 2027 revenue or stretch into later years.
