Stock-comp error forces Ducommun (NYSE: DCO) restatement and control weakness

Rhea-AI Filing Summary

Ducommun Incorporated identified an error in how it accounted for stock-based compensation after changing retirement provisions in April 2024. The mistake affects the timing of expense recognition for retirement-eligible employees and led management to conclude several previously issued financial statements should no longer be relied upon.

The company will restate affected periods by amending its 2025 annual report and has determined the issue caused a material weakness in internal control over financial reporting, making its controls ineffective as of multiple 2024 and 2025 dates. The error is non-cash and does not affect net revenues, gross margin, operating cash flow, or compliance with debt covenants.

Ducommun expects incremental stock-based compensation expense of about $5.0–$6.0 million in Q1 2026 versus prior expectations, but no change to full-year 2026 stock-based compensation. The Compensation Committee expects to claw back roughly $5.0–$6.0 million of incentive pay for 2024 and 2025. The company plans to file an amended 2025 annual report and complete the restatement on or before May 8, 2026.

Positive

• None.

Negative

• Material weakness and non-reliance on prior statements: Ducommun determined there was a material weakness in internal control over financial reporting, and multiple previously issued financial statements and related auditor reports, including as of and for the years ended December 31, 2024 and 2025, should no longer be relied upon.
• Higher near-term stock-based compensation expense: Due to the corrected accounting for retirement-eligible awards, the company expects approximately $5.0–$6.0 million of additional stock-based compensation expense in Q1 2026 relative to prior management expectations.

Insights

Accounting & Governance Analyst

Non-cash stock-comp error triggers restatement and control weakness at Ducommun.

Ducommun found it misapplied GAAP for stock-based awards after revising retirement provisions in April 2024. Expense that should have been accelerated for retirement-eligible employees was instead spread over typical vesting schedules, prompting a restatement of several prior-period financial statements.

The company characterizes the error as non-cash, with no impact on net revenues, gross margin, operating cash flows, or compliance with debt covenants. However, management and the Audit Committee determined there was a material weakness in internal control over financial reporting, meaning controls were not effective as of specified 2024–2025 dates.

For investors, the restatement changes reported earnings quality and highlights control risk rather than liquidity stress. Ducommun expects $5.0–$6.0 million higher stock-based compensation in Q1 2026 versus earlier expectations, and plans a clawback of about $5.0–$6.0 million of prior incentive compensation. Updated details are expected in the amended 2025 annual report targeted by May 8, 2026.

material weakness financial

"The Error and the related Restatement were the result of a material weakness in the Company’s internal control over financial reporting"

A material weakness is a significant flaw in the systems and checks a company uses to ensure its financial reports are accurate, meaning errors or fraud could happen and not be caught. For investors it matters because it raises the risk that reported results are unreliable—similar to finding a hole in a ship’s hull—potentially leading to corrected financials, regulatory action, reduced trust, and negative effects on stock value and borrowing costs.

internal control over financial reporting financial

"material weakness in the Company’s internal control over financial reporting (“ICFR”)"

Internal control over financial reporting is a company’s system of procedures and checks designed to make sure its financial statements are accurate and complete, like a set of guardrails and verification steps that catch mistakes or fraud before numbers are published. Investors care because strong controls make reported results more trustworthy, lower the risk of surprise restatements or regulatory problems, and give greater confidence when valuing the company or comparing it to peers.

Adjusted EBITDA financial

"contains non-GAAP financial measures, including Adjusted EBITDA (which excludes interest expense, income tax expense (benefit), depreciation, amortization, stock-based compensation expense, restructuring charges..."

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

non-GAAP diluted earnings per share financial

"contains non-GAAP financial measures, including Adjusted EBITDA ... and non-GAAP diluted earnings per share"

Non-GAAP diluted earnings per share is a company’s per-share profit figure that starts with reported net income but then removes or alters certain items (like one-time charges, stock-based pay, or other adjustments) and divides by the number of shares after accounting for things that could dilute ownership. Investors use it as a “cleaned-up” measure to judge ongoing profit on a per-share basis, but because companies choose what to adjust, it can be more subjective than the standard GAAP metric—like comparing a regular bank statement to one that omits irregular expenses to show a steadier month-to-month picture.

Item 4.02 Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

While preparing the first quarter 2026 consolidated financial statements of Ducommun Incorporated (the “Company” or “Ducommun”), management identified an error in the Company’s historical consolidated financial statements relating to the timing of stock-based compensation expense recognition (the “Error”). In particular, the Company did not apply the proper accounting for changes made in April 2024 to the retirement provision in the Company’s performance stock unit and restricted stock unit award agreements and did not record stock-based compensation expense in the correct periods for retirement eligible employees. As a result of the changes to the stock unit award agreements in April 2024, the stock-based compensation expense for any employee eligible for retirement on or before the grant date should have been accelerated and fully recognized on the grant date. Further, the stock-based compensation expense related to employees expected to become retirement eligible during the vesting period should have been accelerated and recognized from the grant date through the retirement eligible date instead of being recognized over the typical vesting period applicable to other employees. The Error was non-cash in nature and did not impact the Company’s net revenues, gross margin or net cash provided by (used in) operating activities during the Affected Periods (as defined below).

Due to the identification of this Error, on May 1, 2026, management concluded that the following previously issued financial statements of the Company (and related earnings releases, press releases, shareholder communications, investor presentations or other materials describing relevant portions of such financial statements) should no longer be relied upon:

• the audited consolidated financial statements (the “Previously Issued Annual Financial Statements”) as of and for the fiscal years ended December 31, 2024 and December 31, 2025 contained within the 2025 Annual Report on Form 10-K (and the associated audit report of the Company’s independent registered public accounting firm) (collectively, the “Annual Periods”); and

• the unaudited condensed consolidated financial statements (together with the Previously Issued Annual Financial Statements, the “Previously Issued Financial Statements”) as of and for the quarterly periods ended June 29, 2024, September 28, 2024, March 29, 2025, June 28, 2025 and September 27, 2025 contained within the Quarterly Reports on Form 10-Q for each such completed quarterly period (collectively with the Annual Periods, the “Affected Periods”).

The Audit Committee (the “Audit Committee”) of the Board of Directors (the “Board”) of the Company, in consultation with management, concurred with management’s foregoing conclusion. Accordingly, the Company intends to restate the Previously Issued Financial Statements by amending its Annual Report on Form 10-K for the year ended December 31, 2025 (the “Amended Annual Report”), which will include restated financial statements for the Affected Periods. All material restatement information will be included in the Amended Annual Report (together with the restated financial information for the Affected Periods, the “Restatement”).

As a result of this Error and the correction of certain other immaterial items previously corrected out of period:

• Operating income (loss) was overstated by an estimated $10.0 million for the fiscal year ended December 31, 2024 and by an estimated $3.4 million for the fiscal year ended December 31, 2025.

• Net income (loss) was overstated by an estimated $9.8 million for the fiscal year ended December 31, 2024 and by an estimated $3.4 million for the fiscal year ended December 31, 2025.

• Diluted (loss) earnings per share was overstated by an estimated $0.65 for the fiscal year ended December 31, 2024 and by an estimated $0.22 for the fiscal year ended December 31, 2025 and adjusted diluted earnings per share was overstated by an estimated $0.65 for the fiscal year ended December 31, 2024 and by an estimated $0.22 for the fiscal year ended December 31, 2025.

• Adjusted EBITDA was overstated by an estimated $0.9 million for the fiscal year ended December 31, 2024 and understated by an estimated $0.5 million for the fiscal year ended December 31, 2025.

• Gross margin for the fiscal years ended December 31, 2024 and 2025 was not affected.

• Cash flow from operations and free cash flow for the fiscal years ended December 31, 2024 and 2025 was not affected.

Moreover, the restatement of the Company’s Previously Issued Financial Statements and the other impacts related to the Error do not affect the Company’s compliance with the financial covenants contained in its outstanding debt instruments. Please refer to “Note Regarding Non-GAAP Financial Information” below for further information regarding Adjusted Diluted Earnings Per Share and Adjusted EBITDA.

These matters did not involve any intentional misconduct with respect to the Company, its management or its employees. These estimates reflect preliminary information based on facts available to the Company’s management as of the date of this report and are subject to potential further changes upon completion of the Company’s financial review and restatement procedures, which are expected to be completed on or before May 8, 2026.

Pursuant to the Company’s Second Amended and Restated Clawback Policy, which is detailed under the heading “2026 Compensation Discussion and Analysis—2025 Named Executive Officer Compensation—Second Amended and Restated Clawback Policy” in the Company’s Definitive Proxy Statement filed with the Securities and Exchange Commission (the “SEC”) on March 13, 2026, the Compensation Committee of the Board currently expects to seek the recoupment of approximately $4.3 million to $4.9 million in incentive-based compensation for the fiscal year ended December 31, 2024 and approximately $0.7 million to $1.1 million for the fiscal year ended December 31, 2025. While such clawback would partially offset the impact of the reduction in earnings noted above, in accordance with GAAP, the recoupment will be recognized by the Company in the period in which the recouped amounts are actually received by the Company. The Compensation Committee intends to complete the clawback process promptly.

The Error and the related Restatement were the result of a material weakness in the Company’s internal control over financial reporting (“ICFR”). As a result, management has concluded that the Company’s ICFR was not effective as of December 31, 2025, and the Company’s disclosure controls and procedures were not effective as of June 29, 2024, September 28, 2024, December 31, 2024, March 29, 2025, June 28, 2025, September 27, 2025 and December 31, 2025. Accordingly, the Audit Committee of the Board concluded that Management’s Report on Internal Control over Financial Reporting as of December 31, 2025 should no longer be relied upon.

The Company’s remediation plan will be described in more detail in an amended Item 9A of Part II, which will be included in an amended Annual Report on Form 10-K for the year ended December 31, 2025. The Company currently expects to file an amended Annual Report on Form 10-K/A for the year ended December 31, 2025 on or before May 8, 2026.

The Company also currently expects to release its 2026 first quarter financial results as originally scheduled on May 12, 2026, prior to the stock market opening. Due to the identification of this Error and the revised accounting treatment for stock-based compensation expense going forward, the Company expects to incur higher stock-based compensation expense of approximately $5.0 million to $6.0 million in Q1 2026 relative to prior management expectations. The Company’s does not expect a change to its expectations for stock-based compensation expense for the full fiscal year 2026 as a result of the revised accounting treatment.

The Audit Committee and the Board, along with management, discussed with PricewaterhouseCoopers LLP (“PwC”), the Company’s independent registered public accounting firm, the matters disclosed in this filing pursuant to this Item 4.02. As a result of the above, PwC’s report on the Company’s consolidated financial statements as of and for the years ended December 31, 2024 and December 31, 2025 and PwC’s report on the effectiveness of the Company’s ICFR as of December 31, 2025 should no longer be relied upon.

Note Regarding Non-GAAP Financial Information

This Current Report on Form 8-K (the “Report”) contains non-GAAP financial measures, including Adjusted EBITDA (which excludes interest expense, income tax expense (benefit), depreciation, amortization, stock-based compensation expense, restructuring charges, professional fees related to unsolicited non-binding acquisition offer, litigation settlement and related costs, net, loss extinguishment of debt, other debt refinancing costs, gain on sale of property and other assets, and inventory purchase accounting adjustments) and non-GAAP diluted earnings per share.

FAQ

What accounting error did Ducommun (DCO) disclose in this 8-K?

Ducommun disclosed an error in timing of stock-based compensation expense after changing retirement provisions in April 2024. Expense for retirement-eligible employees should have been accelerated but was instead recognized over standard vesting periods, requiring restatement of affected historical financial statements.

Which Ducommun (DCO) financial statements can no longer be relied upon?

Management and the Audit Committee concluded various previously issued financial statements, along with related earnings releases and PwC’s audit reports for the years ended December 31, 2024 and 2025, should no longer be relied upon. These periods will be restated in an amended 2025 annual report.

How does the Ducommun (DCO) stock-based compensation error affect cash flow and covenants?

The company states the error is non-cash and did not affect net revenues, gross margin, or net cash provided by or used in operating activities. It also reports that the restatement and related impacts do not affect compliance with financial covenants in Ducommun’s outstanding debt instruments.

What additional expenses will Ducommun (DCO) record in Q1 2026 from the error?

Due to the revised accounting for stock-based compensation, Ducommun expects Q1 2026 stock-based compensation expense to be approximately $5.0–$6.0 million higher than prior internal expectations. The company does not expect a change to its overall full-year 2026 stock-based compensation outlook from this adjustment.

Is Ducommun (DCO) seeking to claw back executive compensation after the restatement?

Under its Second Amended and Restated Clawback Policy, the Compensation Committee expects to recoup about $4.3–$4.9 million of 2024 incentive-based compensation and about $0.7–$1.1 million for 2025. Any recovered amounts will be recognized in the period received under GAAP.

What control and disclosure conclusions did Ducommun (DCO) reach?

Ducommun concluded the error and restatement resulted from a material weakness in internal control over financial reporting. Management determined ICFR was not effective as of December 31, 2025, and disclosure controls and procedures were not effective at several 2024–2025 quarter-ends, prompting a forthcoming remediation plan.
