Ducommun Incorporated (DCO): PESTLE Analysis [Nov-2025 Updated]

You're looking for a clear, fact-based breakdown of the macro forces shaping Ducommun Incorporated right now. As a defense and aerospace supplier, Ducommun is defintely a play on geopolitical stability and commercial aviation recovery, but the 2025 numbers show a clear shift in risk and opportunity. Here is the PESTLE analysis, grounded in the latest fiscal year data.

Political Factors: Defense Dependence and Geopolitical Tailwinds

Ducommun Incorporated's near-term outlook is inextricably linked to U.S. defense spending, which drives a significant 55% of its total revenue. This dependency is a double-edged sword: it provides stable, long-cycle contracts but also makes the company highly sensitive to the annual defense budget debates in Congress. The good news is that tariff risk is minimal, as about 95% of the company's revenue originates from its U.S. facilities. You don't have to worry much about trade wars here.

Still, the routine, extensive audits by the Defense Contract Audit Agency (DCAA) mean compliance costs are a constant factor. But honestly, the current geopolitical tensions are a clear tailwind, increasing the demand for complex missile and radar platforms that Ducommun supplies. The defense budget is a political football, but the need for advanced hardware isn't.

Economic Factors: Growth Targets and Debt Management

The economic picture shows resilience. Ducommun Incorporated reported record Q3 2025 net revenue of $212.6 million, an impressive increase of 6% year-over-year. This strong defense growth is what's offsetting the persistent weakness in the commercial aerospace sector, particularly around major programs like the Boeing 737 MAX.

Management's ambitious Vision 2027 targets are the key metric to watch: they aim for $950 million in total revenue and an 18% Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) margin. Plus, the company has done a solid job managing its balance sheet, with interest expense dropping to just $2.9 million in Q3 2025 due to lower debt levels. That's smart capital allocation.

Sociological Factors: Talent and Labor Risk

With a workforce of 2,180 employees as of late 2024, talent retention in specialized engineering and manufacturing roles is a critical focus. The company has made measurable progress on safety, reducing its Total Recordable Incident Rate by an impressive 54% over the last four years, which helps with employee morale and insurance costs. Core values emphasizing Trust and Teamwork are essential for the high-reliability work required in defense systems.

However, a near-term labor risk exists: one collective bargaining agreement is set to expire in April 2025. What this estimate hides is the potential for wage inflation and operational disruption if negotiations stall. You need a clear plan for that negotiation.

Technological Factors: Strategic Product Shift and Compliance Cost

Ducommun Incorporated is executing a strategic mix shift toward higher-margin engineered products, which now account for 23% of total revenue. This is a good move for margin expansion. Continuous innovation in complex electronic and structural systems is paramount for retaining prime contractor status, and they are leveraging technologies like VersaCore Composite™ for next-generation structural components.

On the risk side, increased investment in cybersecurity for Cybersecurity Maturity Model Certification (CMMC) compliance is a mandated, near-term cost that will eat into operating expenses. CMMC is the Department of Defense's new standard to protect sensitive unclassified information, and you can't bid on contracts without it.

Legal Factors: The $99.7 Million Litigation Hit

The legal environment is where the company saw a major impact in 2025. The Q3 2025 net loss of $(64.4) million was almost entirely driven by a massive, one-time $99.7 million litigation charge. This charge relates to pending subrogation claims following a fire at the Guaymas facility, and it's a huge hit to the bottom line.

Beyond this specific event, Ducommun Incorporated must constantly comply with the stringent Defense Federal Acquisition Regulation Supplement (DFARS) rules, which govern everything from procurement to data security. Compliance with the new CMMC is also a mandatory legal hurdle now. You must factor in the cost of that legal liability.

Environmental Factors: Emissions and Remediation Liability

The company has made solid progress on its environmental footprint, reducing Scope 1 and 2 Greenhouse Gas (GHG) emissions by 50% in 2024 versus its 2019 baseline. This helps manage climate-related regulatory costs and improves their Environmental, Social, and Governance (ESG) profile. Still, compliance with hazardous material laws is a constant, uninsurable liability in this industry.

There is also the risk of future capital expenditures for environmental remediation at certain legacy sites. Finance needs to draft a 13-week cash view by Friday that explicitly models the capital outlay for any anticipated environmental cleanup costs.

Ducommun Incorporated (DCO) - PESTLE Analysis: Political factors

U.S. defense spending drives revenue, creating budget dependency.

You need to understand that Ducommun Incorporated's financial performance is intrinsically tied to the U.S. government's defense budget, making it highly sensitive to political shifts in Washington, D.C. This dependency is currently a strong tailwind, but it also represents a single-customer concentration risk.

The company's military and space end-use markets have been the primary growth engine in 2025, offsetting weakness in commercial aerospace. For instance, the military and space segment's revenue increased by $13.8 million in the second quarter of 2025 and another $14.2 million in the third quarter of 2025, compared to the same periods in the prior year. This strong performance helped drive the company's Q3 2025 net revenue to a record $212.6 million.

Here's the quick math: The defense segment's growth was 16% year-over-year in Q2 2025, demonstrating its critical role in the overall revenue picture. Any significant, unexpected cuts to the Department of Defense (DoD) budget would immediately pressure the company's top line and its long-term remaining performance obligations (RPO), which hit a record high with a book-to-bill ratio of 1.6x in Q3 2025.

Minimal tariff risk, as 95% of revenue comes from U.S. facilities.

The risk from shifting U.S. trade policies, such as new tariffs or trade barriers, is defintely low for Ducommun. This is a clear strategic advantage, simplifying supply chain management and reducing exposure to global trade wars.

The company has publicly confirmed its commitment to American manufacturing, with over 95% of its revenue derived from operations based in the United States. This domestic focus means that the most common political risk-tariffs on imported goods-is largely mitigated. What this estimate hides is that the company is still making progress in largely mitigating raw materials tariff exposures through either duty exemptions on military products or by passing costs through to customers under contract terms.

Extensive audits by the Defense Contract Audit Agency (DCAA) are routine.

As a major U.S. defense contractor, Ducommun operates under constant scrutiny from the Defense Contract Audit Agency (DCAA). This is simply a cost of doing business in the defense sector, but it introduces a continuous compliance risk.

The DCAA performs extensive audits to verify the accuracy and appropriateness of costs and expenses used to substantiate direct and indirect costs for U.S. government contracts. This regulatory environment requires a robust internal control over financial reporting (ICFR) framework. Failure to comply can lead to contract price adjustments, penalties, or even suspension from government contracting, though Ducommun's filings note this is a standard, ongoing risk.

Geopolitical tensions increase demand for missile and radar platforms.

Geopolitical instability, while a global concern, acts as a significant demand driver for Ducommun's specialized products. Rising global safety threats and current national defense initiatives are tailwinds that drive sustainable growth.

The ongoing conflicts and great power competition have translated directly into increased orders for specific, high-cost-of-failure applications. This is why you see continued strength in key product lines, including select missiles, electronic warfare, military radar, and military rotary-wing aircraft platforms. The company's missile franchise, in particular, has seen strong, consistent growth throughout 2025.

This reality means that while global politics are turbulent, the need for advanced, mission-critical military and space programs is accelerating, directly benefiting Ducommun's Electronic Systems segment, which reported revenue of $123.1 million in Q3 2025 [cite: 6 from previous search].

Political Factor	2025 Financial/Operational Impact	Actionable Insight
U.S. Defense Budget Dependency	Military/Space revenue increased by $14.2 million in Q3 2025, driving record revenue of $212.6 million.	Monitor Congressional budget debates for Fiscal Year 2026 defense appropriations.
Tariff & Trade Policy Risk	Minimal impact; 95% of revenue is U.S.-based. Raw material tariff exposure is largely mitigated via duty exemptions.	Low-priority risk; focus on domestic supply chain stability over international trade policy.
Regulatory Scrutiny (DCAA)	Requires significant resources for compliance and audit defense; a routine, continuous operational cost.	Ensure internal controls are robust to prevent contract price adjustments.
Geopolitical Tensions	Strong demand for missile and radar platforms; defense segment saw 16% growth in Q2 2025.	Prioritize R&D investment in Electronic Systems segment to capitalize on this demand driver.

Ducommun Incorporated (DCO) - PESTLE Analysis: Economic factors

You're looking for a clear read on Ducommun Incorporated's (DCO) economic foundation, and the Q3 2025 results give us a very distinct picture: it's a tale of two markets. The company is successfully leveraging its defense strength to power growth, even while navigating persistent turbulence in the commercial aerospace sector. This resilience is defintely the key economic takeaway.

Q3 2025 Net Revenue Hit a Record $212.6 Million, Up 6% Year-over-Year

Ducommun delivered a record quarter, proving that its strategy of focusing on high-value, engineered products is working. Net revenue for the third quarter of 2025 reached a new all-time high of $212.6 million. This represents a solid 6% year-over-year (YoY) increase from the $201.4 million reported in the third quarter of 2024. Here's the quick math: the company added over $11 million in revenue, mostly driven by military demand. What this estimate hides is the operational efficiency gains, which pushed the Adjusted EBITDA margin to 16.2%, up 40 basis points YoY.

Strong Defense Growth Offsets Commercial Aerospace Weakness (e.g., Boeing 737 MAX)

The economic environment for Ducommun is currently bifurcated. The defense sector is booming, providing a crucial counterbalance to the slower-than-expected recovery in commercial aviation. Military and space end-use markets saw a revenue increase of $14.2 million in Q3 2025. This robust demand stemmed from higher production rates on platforms like selected missiles, military rotorcraft, and fixed-wing aircraft.

Still, the commercial aerospace market remains a drag. Revenue in this segment was lower by $8.1 million during the quarter. The weakness is largely attributable to continued destocking at major Original Equipment Manufacturers (OEMs) like Boeing and Spirit AeroSystems, even as underlying production rates for platforms such as the 737 MAX are expected to increase. This inventory burn must finish before we see a true commercial rebound for suppliers like Ducommun.

Q3 2025 Financial Metric	Amount	YoY Change / Margin
Net Revenue	$212.6 million	Up 6% YoY
Defense Revenue Increase	$14.2 million	Strong Growth (13% YoY)
Commercial Aerospace Revenue Decline	$8.1 million	Down 10% YoY
Adjusted EBITDA	$34.4 million	Up 8% YoY / 16.2% of Revenue
Interest Expense	$2.9 million	Down from $3.8 million in Q3 2024

Vision 2027 Targets $950 Million Revenue and an 18% Adjusted EBITDA Margin

The company's long-term economic strategy, Vision 2027, sets clear, aggressive financial targets. Management is aiming for net revenues of approximately $950 million by 2027. More importantly for profitability, the goal is to expand the Adjusted EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) margin to 18%. This margin expansion is being driven by operational efficiencies, facility consolidation, and a strategic shift to increase the proportion of higher-margin engineered products and aftermarket services to over 25% of total revenue.

Interest Expense Dropped to $2.9 Million in Q3 2025 Due to Lower Debt

One positive sign in the capital structure is the reduced cost of debt. Interest expense for Q3 2025 fell to $2.9 million. This is a significant drop from the $3.8 million reported in the same quarter of the prior year, a reduction of nearly 24%. This improvement is due to two key factors:

• Lower overall debt balance, showing effective deleveraging.
• Favorable impact from lower interest rates and interest rate hedging contracts.

Lower interest expense directly translates into higher net income, which is crucial for funding internal growth initiatives and potential acquisitions. It's a smart move to shore up the balance sheet while the defense segment is generating strong cash flow. Finance: draft a sensitivity analysis on the 2026 budget assuming a 100 basis point rise in the Fed Funds rate by end of Q2.

Ducommun Incorporated (DCO) - PESTLE Analysis: Social factors

You're looking at Ducommun Incorporated, a company deeply embedded in the high-stakes world of aerospace and defense, so the social factors-specifically the stability, skill, and safety of its workforce-are not merely a matter of corporate responsibility; they are a direct input to product quality and, ultimately, contract performance. The near-term focus is defintely on managing labor relations and retaining specialized talent in a competitive market.

Workforce of 2,180 employees as of late 2024 requires talent retention focus.

As of late 2024, Ducommun Incorporated's global workforce stood at 2,180 employees. This is a specialized team, and the company's success hinges on its ability to attract and retain key engineering, technical, and managerial personnel. Losing a few experts in a highly complex area like electronic systems or structural solutions can slow down a program, so competition for this talent is a very real risk, especially against larger aerospace and defense competitors. The need for a strong talent pipeline is constant.

Here's a quick look at the human capital metrics that matter:

• Total Employees (as of 12/31/2024): 2,180
• Unionized Employees (subject to April 2025 CBA): 268
• Key Focus: Attracting and retaining specialized engineering and technical staff.

Safety focus reduced the Total Recordable Incident Rate by 54% over four years.

A strong safety culture is non-negotiable in precision manufacturing for aerospace and defense. Ducommun has made significant, measurable progress in this area, which is a positive social indicator and a sign of operational discipline. The company successfully decreased its Total Recordable Incident Rate (TRIR) by 54% over the four-year period ending with the 2024 fiscal year. This focus translates directly into fewer operational disruptions and lower associated costs, plus it builds employee trust.

To be fair, safety performance is a continuous effort, but the trend is strong:

Safety Metric	Performance Highlight (as of 2024)	Context
Total Recordable Incident Rate (TRIR) Reduction	54% reduction over four years	Demonstrates a sustained commitment to operational safety and risk mitigation.
Lost Time Incidents	Only three lost time incidents since 2022	Indicates a high level of control over serious workplace injuries.
Total Lost Time Incident Rate (LTIR)	89% reduction in the LTIR since 2019	Shows a dramatic improvement in preventing injuries that lead to missed workdays.

Core values emphasize Trust and Teamwork, crucial for high-reliability defense work.

The company's core values-Honesty, Professionalism, Respect, Trust, and Teamwork-are not just boilerplate; they are essential for a supplier of mission-critical components. When you're building parts for a fighter jet or a space program, collaboration and mutual reliance are paramount. This emphasis on a 'People First' culture and transparent communication helps align the workforce with the strategic direction, which is critical for maintaining the high-quality, zero-defect standard required by major customers like Boeing.

Labor risk exists, with one collective bargaining agreement expiring in April 2025.

A near-term labor risk is present. One of Ducommun's performance centers is party to a collective bargaining agreement (CBA) that covers 268 full-time hourly employees and is set to expire in April 2025. While the company notes that it has not experienced any material labor-related work stoppages and considers relations to be good, the expiration of a CBA always introduces a possibility of disruption. A work stoppage, even a short one, at a single performance center could impact production schedules and customer delivery commitments, so this negotiation will be a key event in Q2 2025.

Ducommun Incorporated (DCO) - PESTLE Analysis: Technological factors

You're looking at Ducommun Incorporated (DCO) and its long-term viability, and honestly, the technology story is a clear-cut case of strategic evolution. The company is actively shifting its focus from being a high-volume contract manufacturer to a specialized, high-margin engineered products provider. This isn't just a buzzword; it's a fundamental business model change aimed at boosting profitability.

This technological pivot is already showing up in the financials for the 2025 fiscal year, even with headwinds in commercial aerospace. You need to focus on this mix shift and the proprietary technologies that underpin it, plus the non-negotiable cost of defense-grade cybersecurity.

Strategic mix shift to engineered products, now 23% of total revenue.

The core of Ducommun's Vision 2027 strategy is to increase the revenue contribution from its Engineered Products portfolio. This category-which includes complex electronic and structural systems-drives higher gross margins (profitability) compared to simple contract manufacturing.

As of the end of the third quarter of 2025, engineered products and aftermarket content accounted for 23% of total revenue. This is a significant jump from the 15% reported in 2022, and it's right on track for the stated goal of surpassing 25% by 2027. Here's the quick math on recent performance:

Metric	Q1 2025 Data	Q3 2025 Data	Strategic Implication
Net Revenue	$194.1 million	$212.6 million	Revenue growth despite commercial aerospace destocking.
Engineered Products % of Revenue	23%	23%	Consistent progress toward the 25%+ Vision 2027 target.
Adjusted Gross Margin	26.6%	26.6%	Record-level margins, defintely helped by the product mix shift.

This shift is a deliberate move to insulate the company from cyclical volume swings in basic manufacturing, and it's working-the gross margin has been at a record 26.6% for both Q1 and Q3 2025.

Continuous innovation in complex electronic and structural systems is paramount.

You can't hit those margin targets without proprietary, high-value technology. Ducommun's competitive edge rests on its ability to innovate within its two core segments: Electronic Systems and Structural Systems. In Electronic Systems, this means advanced radio frequency (RF) products, motors, and resolvers used in missile guidance and electronic warfare. In Structural Systems, it's about making parts lighter, stronger, and with fewer total components.

The focus is on providing an integrated solution, not just a part.

• Develop complex circuit card assemblies for next-generation electronic warfare systems (NGJ).
• Engineer high-performance blades for military platforms like the Apache helicopter.
• Integrate mechanical and electrical components directly into structural assemblies to reduce part count.

Utilizing technologies like VersaCore Composite™ for structural components.

A concrete example of this proprietary technology is the VersaCore Composite™ system. This is a patented, game-changing process for manufacturing complex aerostructures. Instead of assembling many small pieces, which is time-consuming and prone to tolerance stack-ups, this technology creates net-molded, lofted composite parts.

What this means for customers and DCO is a significant reduction in manufacturing complexity and cost.

• Low Part Count: Replaces numerous traditional parts with a single, integrated component.
• Seamless Construction: Eliminates the need for secondary bonds, improving aerodynamic performance.
• Fast Cycle Times: The entire process, including foam molding and Resin Transfer Molding (RTM), can take less than one day.

This technology is already proven on critical defense and commercial platforms, including the C-17 transport aircraft and components for a high-rate single-aisle commercial aircraft engine nacelle contract valued at greater than $200 million through 2029.

Increased investment in cybersecurity for CMMC compliance is a near-term cost.

The technological landscape isn't just about product innovation; it's also about protection, especially when 95% of Ducommun's revenue is U.S.-based and heavily tied to the Department of Defense (DoD). The Cybersecurity Maturity Model Certification (CMMC) is a non-negotiable cost of doing business.

Ducommun is already using the National Institute of Standards and Technology (NIST) Framework, but the CMMC 2.0 Final Rule, which took effect in late 2024, mandates third-party certification for contractors handling Controlled Unclassified Information (CUI).

This compliance is a near-term financial reality. For a company of Ducommun's size and complexity, achieving the mandatory CMMC Level 2 certification-which requires 110 controls based on NIST SP 800-171-will require a substantial investment. The total first-year cost for a typical medium-to-large defense contractor pursuing Level 2 is estimated to range from $175,000 to over $285,000, including preparation, technology upgrades, and the official assessment fee. This is a necessary expense that protects the defense backlog, which stood at $620 million in Q1 2025.

The next step is for the IT and Finance teams to finalize the CMMC Level 2 budget and vendor selection by the end of Q4 2025.

Ducommun Incorporated (DCO) - PESTLE Analysis: Legal factors

The legal landscape for Ducommun Incorporated is currently dominated by two major areas: the financial fallout from a significant litigation settlement and the intensifying regulatory demands of U.S. defense contracting, particularly around cybersecurity compliance.

Q3 2025 net loss of $(64.4) million due to a $99.7 million litigation charge.

You need to look past Ducommun's record revenue of $212.6 million for Q3 2025 to see the real legal impact. The company reported a GAAP net loss of $(64.4) million, or $(4.30) per diluted share, for the quarter. This loss was almost entirely driven by a one-time litigation settlement and related costs totaling $99.7 million.

Here's the quick math: The settlement was for $150 million to resolve the lawsuit with Williams International Co., LLC related to the 2020 fire at the Guaymas, Mexico facility. Ducommun expects $56 million of that to be covered by insurance, leaving a net expense of $94 million, plus approximately $4 million in related legal expenses for Q3 2025. This single event dramatically skewed the GAAP results, even as non-GAAP adjusted net income was a positive $15.2 million, or $0.99 per diluted share.

Q3 2025 Financial Metric	Amount (in millions)	Impact Source
Net Revenue	$212.6	Operational Performance (Up 6% YoY)
GAAP Net Loss	$(64.4)	Litigation Settlement
Litigation Settlement & Related Costs, Net	$99.7	Guaymas Fire Lawsuit
Gross Settlement Amount	$150.0	Williams International Co., LLC Claim
Insurance Recovery (Expected)	$56.0	Insurance Coverage
Non-GAAP Adjusted Net Income	$15.2	Underlying Operational Performance

Must comply with Defense Federal Acquisition Regulation Supplement (DFARS).

As a major supplier to the U.S. Department of Defense (DoD), Ducommun is defintely subject to the strict requirements of the Defense Federal Acquisition Regulation Supplement (DFARS). This isn't just a compliance formality; it's a condition of doing business.

Specifically, DFARS mandates that defense contractors adequately safeguard Controlled Unclassified Information (CUI). Failure to comply with these procurement laws and regulations can lead to severe consequences, including contract termination, fines, and reputational damage. This is a constant, high-stakes legal risk that demands continuous internal investment in compliance infrastructure.

Subject to pending subrogation claims related to a fire at the Guaymas facility.

Even with the primary Williams International lawsuit settled, the legal risk from the 2020 Guaymas fire isn't entirely extinguished. Ducommun remains subject to pending subrogation claims. Subrogation is when an insurer steps into the shoes of the insured party to recover a loss payment from the party who caused the loss.

The company has disclosed a few specific, smaller liabilities:

• A subrogation claim from an intervening insurer in the Williams International litigation, which the company expects to settle for approximately $1.35 million.
• Additional expenses of approximately $3 million in future periods related to a separate subrogation claim asserted by the insurer of the entity that provides labor and facilities for the Guaymas performance center.

These claims, while small compared to the $150 million settlement, show how a single incident creates a long tail of legal and financial exposure.

Compliance with the Cybersecurity Maturity Model Certification (CMMC) is mandated.

The most significant near-term regulatory shift is the Cybersecurity Maturity Model Certification (CMMC) program. The mandate has moved from a future threat to an immediate requirement with the 48 CFR CMMC Acquisition Rule becoming effective on November 10, 2025.

This means new DoD solicitations are now including CMMC requirements, making certification a condition of eligibility for new defense work. For Ducommun, which handles CUI, this will likely require a CMMC Level 2 certification, involving a third-party assessment (C3PAO). Ducommun is actively incorporating CMMC requirements into its overall cybersecurity program, but the full rollout and mandatory compliance for all new DoD contract awards is expected by October 31, 2026, with full implementation by 2028. This is a critical action item to protect their defense revenue stream.

Next Step: Legal and IT teams must finalize the CMMC Level 2 gap analysis and secure a C3PAO engagement by the end of Q4 2025 to ensure eligibility for key 2026 contract bids.

Ducommun Incorporated (DCO) - PESTLE Analysis: Environmental factors

The environmental landscape for Ducommun Incorporated is defined by a strong, measurable commitment to de-carbonization, but it's also shadowed by the perennial, high-cost risks inherent in manufacturing for the aerospace and defense sectors. You need to see the success in emissions reduction as a cost-management win, but stay realistic about the uninsurable liabilities tied to legacy site contamination.

Reduced Scope 1 and 2 GHG emissions by 50% in 2024 versus 2019 baseline.

Ducommun has made serious, verifiable progress on its carbon footprint, which is a major positive for both regulatory and investor sentiment in the 2025 fiscal year. The company achieved an absolute reduction of its combined Scope 1 (direct) and Scope 2 (indirect) Greenhouse Gas (GHG) emissions by a full 50% in 2024, benchmarked against its 2019 baseline. That's a huge step toward de-carbonizing operations.

The reduction wasn't evenly split, which shows where the biggest wins came from. Scope 2 emissions-mostly from purchased electricity-saw a steep 55% cut, likely due to increased renewable energy reliance and efficiency projects. Scope 1 emissions, from sources like on-site natural gas and vehicle fuel, dropped by a respectable 33%. This isn't just good PR; it translates directly into lower energy costs and a buffer against future carbon taxes.

GHG Emissions Reduction (2024 vs. 2019 Baseline)	Reduction (Absolute Basis)	Impact
Combined Scope 1 and 2 Emissions	50%	Strong defense against climate-related regulatory risk.
Scope 2 Emissions (Purchased Electricity)	55%	Indicates successful energy procurement and efficiency projects.
Scope 1 Emissions (Direct Sources)	33%	Shows progress in on-site fuel/natural gas consumption.

Compliance with hazardous material laws is a constant, uninsurable liability.

Working in advanced manufacturing for defense means you deal with hazardous materials every day, and that creates a constant, unquantifiable risk. Ducommun's operations are subject to stringent regulations like the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), among others. The company's 2024 Annual Report confirms that compliance with existing or future environmental laws may require extensive capital expenditures and could adversely affect financial results. To be fair, they manage their waste well.

For example, in 2023, Ducommun reclaimed, recycled, and reused 99% of the hazardous waste it generated, and 82% of the chemicals used in its processes. That's a phenomenal operational metric, but it doesn't eliminate the underlying liability risk. You can't insure against the risk of a new, unforeseen regulation that suddenly makes a common chemical illegal or forces a billion-dollar cleanup. It's a risk you simply have to manage through best practices and robust Environmental, Health, and Safety (EHS) systems.

Risk of future capital expenditures for environmental remediation at certain sites.

A key financial risk you need to track is the potential for unexpected capital expenditures (CapEx) related to historical contamination. Ducommun has disclosed that it has been directed to investigate and take corrective action for groundwater contamination at certain sites. The ultimate liability for these matters is uncertain and dependent on factors like the scope of contamination and regulatory requirements.

This is where the rubber meets the road: environmental remediation costs are often a CapEx black hole. While current financial statements account for known liabilities, the risk is that the scope of these cleanups expands significantly. Any major change in the regulatory environment, or the discovery of a wider plume of contamination, could trigger a substantial, unplanned cash outlay that directly hits the balance sheet. You need to budget for the unknown here.

Focus on energy efficiency projects to manage climate-related regulatory costs.

The company's strategy to manage climate-related regulatory costs is focused on operational efficiency and a shift to cleaner energy. This proactive approach is a smart way to get ahead of potential carbon pricing or energy mandates. A major part of this effort is energy efficiency projects, like the installation of LED lighting, which Ducommun has completed at eleven performance centers.

This focus has already paid off in the form of increased renewable energy use, which reached approximately 34,121 Gigajoules (9.5 million kWh) in 2023 compared to the 2019 baseline. This investment in efficiency is a clear action to mitigate the risk of rising energy costs and climate-related regulatory burdens. It's a classic example of turning an environmental risk into an operational efficiency gain.

• Increase renewable energy use: Reached 34,121 GJ in 2023.
• Implement LED lighting: Completed at eleven performance centers.
• Target total energy reduction: Total energy usage decreased by 16% in 2023 versus the 2019 baseline.

The next step for you is to monitor the 2025 CapEx line items for any material increase in 'Environmental Remediation' spending, as that will be the first signal of an expanding liability at those legacy sites. Finance: flag any environmental CapEx exceeding $5 million in a single quarter for immediate review.
