Risk factors and legal proceedings
The risks Mistras Group, Inc. names in Item 1A of its 10-K filed Mar 11, 2026: 32 risks under these headings, as written.14
- Risks Related to Our Business
- Due to our dependency on customers in the oil and gas industry, we are susceptible to prolonged negative trends relating to this industry that could adversely affect our operating results.
- If we are unable to successfully execute our growth strategy, our business, financial condition, and results of operations could be materially and adversely affected
- We may be affected by climate change and market or regulatory responses to climate change
- Our international operations are subject to risks relating to non-U.S. operations.
- Our operating results could be adversely affected by a reduction in business with our significant customers.
- Our business, and the industries we currently serve, are currently subject to governmental regulation, and may become subject to modified or new government regulation that may negatively impact our ability to market our asset protection solutions.
- An accident or incident involving our asset protection solutions could expose us to claims, harm our reputation and adversely affect our ability to compete for business and, as a result, harm our operating performance.
- Many of the sites at which we work are inherently dangerous workplaces. If we fail to maintain a safe work environment, we may incur losses and lose business.
- If our software or system produces inaccurate information or are incompatible with the systems used by our customers and make us unable to successfully provide our solutions, it could lead to a loss of revenues and customers.
- If we are unable to attract and retain a sufficient number of trained certified technicians, engineers and scientists at competitive wages, changes in laws and other labor issues could materially affect our financial performance.
- Our initiatives to improve our financial performance may not achieve results within expected time frames, or at expected levels.
The other 21 risks
- We operate in competitive markets and if we are unable to compete successfully, we could lose market share and revenues and our margins could decline.
- The success of our businesses depends, in part, on our ability to develop new asset protection solutions, increase the functionality of our current offerings and meet the needs and demands of our customers.
- The seasonal nature of our business reduces our revenues and profitability in the winter and summer and related cash flows.
- Our credit agreement contains financial and operating restrictions that may limit our access to credit. If we fail to comply with financial or other covenants in our credit agreement, we may be required to repay indebtedness to our existing lenders, which may harm our liquidity.
- Currency exchange rate fluctuations in various currencies in which we do business, especially the Euro and the U.S. dollar, could have a material adverse effect on our business, results of operations and financial condition.
- We face risks regarding our information technology and security.
- Events such as natural disasters, industrial accidents, epidemics, pandemics, war and acts of terrorism, and adverse weather conditions could disrupt our business or the business of our customers, which could significantly harm our operations, financial results and cash flow.
- We may use artificial intelligence in our business, which could result in reputational harm, competitive harm, and legal liability, and adversely affect our business, results of operations and financial condition.
- Changes to U.S. tariff and import/export regulations may have a negative effect on us.
- Risks Related to Our Common Stock
- The family of our late founder and Chairman Emeritus may be able to exert significant influence over the direction of our business. The concentrated ownership of our common stock may prevent other stockholders from influencing significant corporate decisions.
- We currently have no plans to pay dividends on our common stock.
- Shares eligible for future sale may cause the market price for our common stock to decline even if our business is doing well.
- Provisions of our certificate of incorporation, bylaws and of Delaware law could discourage, delay or prevent a change of control of our company, which may adversely affect the market price of our common stock.
- General Risk Factors
- Our stock price could fluctuate for numerous reasons, including variations in our results.
- Deteriorations in economic conditions in certain markets or other factors may cause us to recognize additional impairment charges for our goodwill.
- We are subject to privacy and data security/protection laws in the jurisdictions in which we operate and may be exposed to substantial costs and liabilities associated with such laws and regulations.
- If we lose key members of our senior management team upon whom we are dependent, we may be less effective in managing our operations and may have more difficulty achieving our strategic objectives.
- Intellectual property may impact our business and results of operations.
- Social, political and economic changes or instability, or other circumstances beyond our control could affect our business operations.
- We may require additional capital to support business growth, which might not be available.
- Changes in Tax Laws, Including the One Big Beautiful Bill Act, Could Adversely Affect Our Effective Tax Rates, Financial Condition, and Results of Operations
Legal proceedings
We are subject to periodic legal proceedings, investigations and claims that arise in the ordinary course of business. See “Legal Proceedings and Government Investigations - Litigation and Commercial Claims” in Note 17-Commitments and Contingencies to our audited consolidated financial statements contained in Item 8 of this Annual Report for a description of legal proceedings involving us and our business, which is incorporated herein by reference.
