Business buyers often encounter unexpected challenges. One particularly thorny issue that can arise is the presence of undocumented workers in a target company. While these employees may seem like a solution to labor shortages, they pose significant risks that buyers must carefully consider and mitigate.

In a recent discussion on Searchfunder, a community platform for search fund entrepreneurs and investors, a pressing question arose about the risks associated with undocumented workers in business acquisitions. This comprehensive article explores the multifaceted challenges highlighted by experienced searchers and industry professionals in that discussion, providing valuable insights for potential buyers navigating this complex terrain.

The Current Landscape

 

Undocumented workers are a reality in many industries across the United States. According to the Pew Research Center, there were 10.5 million unauthorized immigrants in the U.S. in 2021, making up about 3% of the total U.S. population. Many of these individuals are part of the workforce, particularly in sectors such as agriculture, construction, and hospitality.

Businesses often employ undocumented workers due to labor shortages, particularly for skilled positions that are difficult to fill. In some cases, as one searcher noted, “It is difficult to hire the skill set and typically these workers are your best bet.” This practice, while common, especially in certain industries, carries significant legal and financial risks.

The process of legalizing an undocumented worker’s status is complex and time-consuming. It often involves navigating a maze of immigration laws and can take years to complete. As one expert in our discussion pointed out, claims that workers are “in the process of legalizing their status” should be treated as a “big yellow flag” and warrant deeper investigation.

Risks for Buyers

 

When considering the acquisition of a business that employs undocumented workers, buyers face several categories of risk:

Legal Risks

The legal implications of employing undocumented workers are severe. Under U.S. law, it is illegal to knowingly hire or continue to employ individuals who are not authorized to work in the country. Penalties for violations can be steep:

  • Civil fines can range from $573 to $20,130 per unauthorized worker for first-time offenses, with repeat offenders facing even higher fines.
  • Criminal penalties, including fines and imprisonment, may be imposed for pattern or practice violations.
  • Debarment from government contracts is another potential consequence.
  • Ishan Jetley, Chief Marketing Officer at Edeska LLC, shared a cautionary tale: “I do marketing for a lot of home services business and one client had a raid and had to pay a huge fine. I would avoid especially if you are using SBA/DEBT.

Moreover, government audits have increased in recent years, especially in sectors known to have higher numbers of undocumented workers.  Abigail Russ added, “Do know that post-covid government audits have increased especially in sectors known to have increased numbers of undocumented workers, including with those companies who have contractual relationships with subcontractors with potential gaps.

Financial Risks

The financial implications of acquiring a business with undocumented workers extend beyond potential fines:

  • Labor Costs: If the business has been relying on undocumented workers as a source of cheaper labor, transitioning to a fully documented workforce could significantly increase labor costs.  Josh Beets, Principal at Fugue Capital, pointed out the potential financial impact: “Owner likely hires illegal labor b/c it is cheaper, so if you hire legal labor your costs would increase (assuming you could find that which it sounds like you may not be able to).
  • EBITDA Impact: The increase in labor costs could materially affect the company’s EBITDA, potentially altering the valuation of the business.
  • Financing Challenges: Banks and other financial institutions may be reluctant to finance the acquisition if they become aware of the issue of undocumented workers. As James Cai, an independent contributor warned, “I doubt a bank would finance you if they knew of this. And if they find out later (and realize you knew this), I’m sure they have recourse.

Operational Risks

The operational challenges of addressing an undocumented workforce can be significant:

  • Loss of Skilled Workers: If undocumented workers need to be replaced, the business may lose valuable skills and experience.
  • Training and Transition: New, documented workers may require extensive training, potentially disrupting operations.
  • Knowledge Transfer: There’s a risk of losing institutional knowledge if long-term undocumented workers leave abruptly.

Josh Beets noted, “If you think you can run the company 100% with legal labor, then you would have to adjust the EBITDA for the increase in labor cost (plus the increased risk that you may not be able to find labor and lose current employee knowledge).

Reputational Risks

In today’s socially conscious business environment, the reputational risks of employing undocumented workers cannot be overstated:

  • Negative Publicity: If it becomes public knowledge that the business employs undocumented workers, it could lead to negative press and social media backlash.
  • Customer Relationships: Some customers may choose to distance themselves from a business known to employ undocumented workers.
  • Exit Challenges: James Cai highlighted the long-term reputational risks – “Also, setting aside any potential fines or impact on #s, if you plan on exiting, there is huge risk as many potential buyers would likely be uncomfortable with this potential liability (and potential headline).

Due Diligence Considerations

 

Given these risks, thorough M&A due diligence is crucial when considering the acquisition of a business that may employ undocumented workers. Key areas to investigate include:

  1. HR Audit: Conduct a comprehensive review of the company’s hiring practices, I-9 forms, and employee records.
  2. I-9 Compliance: Verify that I-9 forms are properly completed and maintained for all employees.
  3. Legalization Claims: If the seller claims workers are in the process of legalizing their status, request detailed documentation of these efforts.
  4. Operational Assessment: Evaluate and add to your operational due diligence checklist how critical the potentially undocumented workers are to the business’s operations.
  5. Financial Analysis: Assess the potential impact on labor costs and EBITDA if all workers were to be replaced with documented employees.

 

Mitigation Strategies

 

If you decide to proceed with the acquisition despite the presence of undocumented workers, consider the following mitigation strategies:

Legal Compliance

  • Implement E-Verify: This federal system can help verify the employment eligibility of new hires. Leo Koo, a Solo Searcher, suggested: “If you did want to carry forward taking on the risk, you should look at E-Verify laws, within a wrapper of understanding which State the company operates. If you run the employees through E-Verify, it could give you a layer of protection if you can verify those employees.
  • Proper Classification: Ensure workers are correctly classified as W2 employees or 1099 contractors. As one expert warned, “Other pitfalls to avoid is Companies misclassifying as 1099 contractors vs. W2s to get around undocumented ‘personnel.'”
  • Develop Robust Processes: Implement stringent hiring and verification processes to prevent future issues.

Financial Planning

  • Adjust Financial Models: Factor in potential increases in labor costs when valuing the business.
  • Create Reserves: Set aside funds to cover potential fines or legal fees.

Josh Beets advised adjusting financial models: “If you think you can run the company 100% with legal labor, then you would have to adjust the EBITDA for the increase in labor cost.”

Operational Planning

  • Develop Contingency Plans: Create strategies for maintaining operations if undocumented workers need to be replaced quickly.
  • Invest in Training: Develop comprehensive training programs to quickly bring new workers up to speed.

Atul Kannan, CEO at Zappling, suggested considering “what happens to the cost and operational stability of the business if all these workers left and you replaced them with legal ones.

Contractual Protections

  • Seek Indemnification: Try to negotiate indemnification from the seller for any liabilities related to undocumented workers.
  • Specific Representations: Include detailed representations and warranties in the asset purchase agreement regarding the workforce’s legal status.

Alex Rogalski, Vice President / Board Member, proposed seeking indemnification, though he was skeptical of its effectiveness: “I doubt the seller is willing to agree to full indemnification for any liability associated with non I-9 employees (which you would not want to be liable for unless you or the owner had a very quick way to remedy/mitigate the risk by hiring all I-9s pre-close…).

Expert Opinions

 

The Searchfunder discussion included insights from various experts:

Tony Yannucci, MD at SouthPort Advisory, suggested: “I would get legal counsel (which I am not, to be clear). Depending on the industry, scope, etc., there may be ways to solve or get comfortable with the situation. If it is a good deal, it will be worth some extra dollars on legal.

Atul Kannan provided a comprehensive perspective: “My personal opinion is that it is a big risk and it is a serious violation if knowingly hiring workers who do not have an employment authorization (although I’m sure the consequences and enforcement vary significantly between localities).

Mark Sinatra, Founder of Aspen HR, was unequivocal: “I would pass on this due to the severity of the risk. Even if you try to 1099 those workers that has other potential implications and risk. I would save yourself the headache and pass.”

Conclusion

 

The issue of undocumented workers in business acquisitions presents a complex challenge for buyers. While the allure of acquiring a skilled workforce may be strong, the legal, financial, operational, and reputational risks are significant. Thorough due diligence, careful planning, and expert guidance are essential in navigating these waters.

The Searchfunder discussion overwhelmingly cautioned against acquiring a business with undocumented workers. As Alex Rogalski succinctly put it, it’s “Not worth the risk IMO.

However, the conversation also revealed the complexity of the issue, particularly in industries facing severe labor shortages. As Brandon Spears, President of Splurge Distribution, noted from his experience in commercial construction: “I don’t think it is a deal breaker, but depends on the type of work being done and in what state.

Ultimately, the consensus among the Searchfunder community was that the legal, financial, operational, and reputational risks associated with undocumented workers in a business acquisition are significant. Thorough due diligence, expert legal counsel, and careful consideration of all potential ramifications are essential for any buyer considering such a situation.

Remember, while this guide provides a comprehensive overview based on the Searchfunder discussion, each situation is unique. Always consult with legal and financial professionals before making decisions regarding undocumented workers in a potential business acquisition.

FAQ

Frequently Asked Questions

While acquiring such a business isn’t illegal, knowingly continuing to employ undocumented workers after the acquisition is a serious legal violation.

The main risks include legal penalties, financial implications (such as increased labor costs and potential fines), operational disruptions, and reputational damage. There’s also a risk that this issue could deter future buyers if you plan to exit the business.

This is risky. Claims of ongoing legalization should be treated as a red flag. Even if documentation has been submitted, approval isn’t guaranteed. It’s crucial to verify the status of any legalization efforts.

It could significantly impact valuation. You would need to adjust the EBITDA to account for potentially increased labor costs if transitioning to a fully documented workforce. This could materially affect the company’s financial outlook.

Yes, some industries are known to have higher numbers of undocumented workers. The approach may vary depending on the type of work and the state. However, increased scrutiny is happening across all sectors.

E-Verify can help prevent future hiring of undocumented workers, but it doesn’t solve existing issues. While it could provide some protection, it would only apply to new hires or re-verification processes.

Investigate whether all employees have the legal right to work and if not, what plans are in place to address this. Review all I-9 forms, investigate any claims of ongoing legalization processes, and assess the potential impact on operations and finances if these workers need to be replaced.

While you can seek indemnification, it may not fully protect you. Sellers are often unwilling to agree to full indemnification for liabilities associated with undocumented workers.

It could significantly hinder financing options. Banks and other financial institutions may be unwilling to finance the acquisition if they’re aware of this issue, and there could be serious consequences if they discover it later.

Most experts advise against it due to the severity of the risks involved. However, if you decide to proceed, it would be worth investing in thorough legal counsel to investigate and mitigate the risks.
