Properties, in its own words

On October 31, 2014, we purchased the commercial property we use as our corporate headquarters and certain adjacent property in Wheat Ridge, Colorado. The building consists of 22,325 square feet, all which is used by us for operations. In addition to housing our corporate headquarters, we use this property for research and development, manufacturing, shipping/receiving, warehouse, and inventory purposes. Our purchase of the property was partially financed through a term loan in an original principal amount of $1,581,106, secured by a first-priority mortgage on the property. This loan was paid on September 30, 2021 with proceeds from a new term loan, also secured by a first-priority mortgage on the property, in the principal amount of $1,350,000 which matures in September 2031.

Risk factors and legal proceedings

The risks Lifeloc Technologies, Inc names in Item 1A of its 10-K filed Mar 27, 2026: 35 risks under these headings, as written.3

  • Risks Related to Our Business and Industry
  • Global economic conditions could have a negative impact on our business, operating results and financial condition.
  • Changes in trade policy and tariffs could increase our costs and adversely affect our sales.
  • Geopolitical instability and international conflicts may disrupt our operations, supply chain, and financial performance.
  • We rely on customers who may not consistently purchase our products in the future and if we lose any one of these customers, our revenues may decline.
  • We rely heavily upon the talents of our Chief Executive Officer, the loss of whom could severely damage our business.
  • We must continue to be able to attract employees, including employees with the scientific and technical skills that our business requires, and if we are unable to attract and retain such individuals, our business could be severely damaged. Labor shortages across the country threaten to damage our business.
  • Our growth depends in part on the timely development and commercialization, and customer acceptance, of new and enhanced products and services.
  • Our ongoing investment in new products, services, and technologies is inherently risky, and could disrupt our ongoing businesses.
  • We are subject to a high degree of regulatory oversight, and, if we do not continue to receive the necessary regulatory approvals, our revenues would decline.
  • Our business in the domestic law enforcement area is susceptible to changes in state policies and DUI laws.
  • Our business relies on state contracts, governed by state contracting policies that are beyond our control.
The other 24 risks
  • We derive a significant portion of our revenue directly or indirectly from government customers, and our business may be adversely affected by changes in the contracting or fiscal policies of those governmental entities.
  • Third parties may infringe on our patents, and as a result, we could incur significant expense in protecting our patents or not have sufficient resources to protect them.
  • Third parties may claim that we have infringed on their patents and as a result, we could be prohibited from using all or part of any technology used in our products.
  • Third parties to whom we have licensed our patents may choose to enforce them through litigation, over which we would exert little or no control.
  • Failure of third parties from whom we license key intellectual property to protect their intellectual property could adversely affect our business.
  • We depend on the availability of certain key supplies and services that are available from only a few sources, and if we experience difficulty with a supplier, we may have difficulty finding alternative sources of supply.
  • We may be exposed to claims of liability.
  • We could be liable if our business operations harmed the environment, and a failure to maintain compliance with environmental laws could severely damage our business.
  • Climate change may adversely impact our business.
  • Our quarterly financial results vary quarter to quarter, which adversely affects our stock price at times. We cannot predict with any certainty our operating results in any particular fiscal quarter.
  • Identification of material weakness in internal control may adversely affect our financial results.
  • We may require additional capital in the future, which may not be available or may only be available on unfavorable terms.
  • Our outstanding indebtedness requires ongoing debt service and could limit our financial flexibility.
  • We have a number of large, well-financed competitors who have research and marketing capabilities that are superior to ours.
  • Our products rely on technology that may become outdated or out of favor.
  • Natural disasters, public health crises, political crises, and other catastrophic events or other events outside of our control may damage our facilities or the facilities of third parties on which we depend and could impact customer priorities and consumer spending.
  • Increasingly common data privacy and cybersecurity regulations impact the use of or market for our products.
  • Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price.
  • Risks Related to Our Stock
  • Shares of our common stock lack a significant trading market.
  • Our principal stockholder has significant voting power and may take actions that may not be in the best interests of other stockholders.
  • Stockholders should not anticipate receiving cash dividends on our stock.
  • We may issue shares in the future, diluting your interest in us.
  • General Risk Factors
  • Blue Sky considerations limit sales in certain states.
  • Compliance with changing regulations of corporate governance and public disclosure result in expense.

Legal proceedings

We may be involved from time to time in litigation, negotiation and settlement matters that may have a material effect on our operations or finances. We are not aware of any material pending legal proceedings, other than ordinary routine litigation incidental to our business, to which we are a party or of which any of our property is subject.
