We outsource the manufacturing of all of our products to electronics manufacturing services ("EMS") providers located outside the U.S. If any of these EMS providers experience (i) difficulties in obtaining sufficient supplies of components, (ii) difficulties in obtaining adequate skilled labor, (iii) component prices significantly exceeding anticipated costs, (iv) an interruption in their operations, or (v) otherwise suffers capacity constraints, we could experience a delay in production and shipping of these products, which would have a negative impact on our revenue. Should there be any disruption in services due to natural disaster, economic or political difficulties, transportation restrictions, acts of terror, quarantines or other restrictions associated with infectious diseases, or other similar events, or any other reason, such disruption could have a material adverse effect on our business. Operating in the international outsourcing environment exposes us to certain inherent risks, including unexpected changes in regulatory requirements and tariffs, and potentially adverse tax consequences, which could materially affect our results of operations. Currently, we have no second source of manufacturing for a large portion of our products.
Switching from one EMS provider to another or switching from one location of manufacturing to another location similar to our recent transition from China to Singapore, is an expensive, difficult and a time-consuming process, with serious risks to our ability to successfully transfer our manufacturing operations. Our operations, and consequently our revenues and profitability, were impacted materially in 2021, 2022 and 2023 due to switching of manufacturing from one location to another. Our operations, and consequently our revenues and profitability could be materially adversely affected in the future if we are forced to switch from any of our EMS providers to another EMS provider due to any number of factors, including financial difficulties faced by the manufacturer, disagreements in pricing negotiations between us and the manufacturer or organizational changes in the manufacturer. If our EMS providers experience disruptions in their operations, it is uncertain whether we would be able to source the essential commodities, supplies, materials, and skilled labor timely or at all without incurring significant costs or delays, particularly during times of economic uncertainty resulting from events outside of our control, including, but not limited to, effects of COVID-19. We may be forced to purchase supplies and materials in larger quantities or in advance of when we would typically purchase them. This may cause us to require use of capital sooner than anticipated. Alternatively, we may also be forced to seek new third-party suppliers or contractors, whom we have not worked with in the past, and it is uncertain whether these new suppliers will be able to adequately meet our materials or labor needs. In addition, we may be unable to compete with entities that may have more favorable relationships with their suppliers and contractors or greater access to the required raw materials and skilled labor.
The cost of delivered product from our EMS providers is a direct function of their ability to buy components at a competitive price and to realize efficiencies and economies of scale within their overall business structures. During 2021 there was a worldwide shortage of semiconductor, memory and other electronic components affecting many industries, from automotive to technology providers. Even though this shortage has eased in 2022, the shortage continues to impact our operation. If the shortage continues or worsens it will impact our EMS providers significantly. If our EMS providers are unsuccessful in obtaining component parts at efficient costs or at all, our delivered costs could rise or we may not be able to fulfill orders on time or at all, affecting our gross margins, profitability and ability to compete. In addition, if the EMS providers are unable to achieve greater operational efficiencies, delivery schedules for new product development and current product delivery could be negatively impacted.
EMS providers often require long range forecasts to help them plan their operations as well as to allocate their resources. We are tied to these forecasts through contracts as well as to maintain harmony in business relationships. Our ability to react to actual demand from our customers and order optimum levels of inventory is severely limited due to these forecasts provided to the EMS providers. Our inability to accurately forecast our future demands could lead to either excess inventory causing potential inventory obsolescence and cashflow problems or shortage in inventory causing potential loss of revenue.
Additionally, the sourcing and availability of raw materials necessary for our EMS providers to manufacture certain of our products, including "conflict minerals" has been and could continue to be significantly constrained, which is likely to result in continued elevated price levels. Furthermore, compliance with SEC disclosure and reporting requirements in the future regarding the use of "conflict minerals" mined from the Democratic Republic of Congo and adjoining countries could adversely affect the sourcing, supply and pricing of materials used in our products. As a result, we may not be able to obtain the materials necessary to manufacture our products, which could force us to cease production or search for alternative supply sources, possibly at a higher cost. Such disruptions may have a material adverse effect on our business, financial condition, results of operations and cash flows.
