We are exposed to market risk of increases in certain commodity prices of materials, which are used as components of supplies or materials in our operations. We are also exposed to increases in energy prices. While we believe we can increase our prices to adjust for some price increases in commodities, there can be no assurance that price increases of commodities, if they were to occur, would be recoverable.
Further, the timing of our price increases may lag behind the timing of the underlying increases in commodity or material prices. Even if we are able to raise the prices of our products, consumers might react negatively to such price increases, which could have a material adverse effect on, among other things, our brands, reputation, and sales. If our competitors substantially lower their prices, we may lose customers and mark down prices. Our profitability may be impacted by lower prices, which may negatively impact gross profit and gross profit margin.
Additionally, our fixed-price contracts generally do not allow us to adjust our prices and, as a result, increases in material or fuel costs could reduce our profitability with respect to projects in progress. For example, in recent years, we experienced supply chain delays, including long lead times for certain materials and equipment, as well as an escalation in material and fuel prices, to varying degrees. These disruptions resulted in declines in gross profit and gross profit margin for certain of our operations. Fluctuations in the price of energy and commodity materials, whether resulting from fluctuations in market supply or demand, geopolitical conditions, including supply chain disruptions and sanctions on Russian exports as a result of Russia's invasion of Ukraine and recent shipping lane disruptions, an increase in trade protection measures such as tariffs, or the disruption, modification, or cancellation of multilateral trade agreements, may adversely affect our customers and as a result cause them to curtail the use of our services.
On the other hand, because certain of our service offerings are designed to improve energy efficiency in our clients' operations, or to assist in the generation of new sources of renewable energy, such as wind, solar, and geothermal generation, decreases in the costs of traditional energy sources such as oil and natural gas, including as a result of recessionary pressure and reduced demand, may lower our customers' demand for efficiency improvements and alternative energy sources.
Furthermore, our workforce and equipment are highly mobile and service large geographic areas. Movement of our workforce and equipment within our market area could be negatively impacted by rising fuel costs, third-party freight rate increases and shortages of third-party truck drivers, among other things. We seek to mitigate some or all cost increases through including labor rate changes in project bids, securing material and subcontractor pricing in the project bids and maintaining positive relationships with numerous suppliers, but we may not be successful in our efforts to do so. All of these impacts could have an adverse effect on our business, financial position, results of operations, and cash flows.
