decisions or reorganizational issues, such as roll-out of new equipment or disruptions to information infrastructure or power transmission or navigation miscalculations which may delay or disrupt supply of previously forecasted components, or industry consolidation and divestitures, which may result in changed business and product priorities among certain suppliers. Also, many standardized components used broadly in electronic devices are manufactured in significant quantities in concentrated geographic regions, particularly in Greater China. As a result, protracted crises, geopolitical unrest and uncertain economic conditions, could lead to eventual shortages of necessary components sourced from impacted regions or increased component costs. Additionally, government intervention to curb the consumption of electricity in China could have a disruptive impact on component production and supply availability. It could be difficult, costly and time consuming to obtain alternative sources for these components, or to change product designs to make use of alternative components. In addition, difficulties in transitioning from an existing supplier to a new supplier could create delays in component availability that would have a significant impact on our ability to fulfill orders for our products.
We provide our third-party manufacturers with a rolling forecast of demand and purchase orders, which they use to determine our material and component requirements. Lead times for ordering materials and components vary significantly and depend on various factors, such as the specific supplier, contract terms and demand and supply for a component at a given time. Some of our components have long lead times, such as WiFi chipsets, switching fabric chips, physical layer transceivers, and logic, power, analog and RF chipsets. If our forecasts are not timely provided or are less than our actual requirements, our third-party manufacturers may be unable to manufacture products in a timely manner. If our forecasts are too high, our third-party manufacturers will be unable to use the components they have purchased on our behalf. Historically, the cost of the components used in our products tends to drop rapidly as volumes increase and the technologies mature. Therefore, if our third-party manufacturers are unable to promptly use components purchased on our behalf, our cost of producing products may be higher than our competitors due to an oversupply of higher-priced components. Moreover, if they are unable to use components ordered at our direction, we will need to reimburse them for any losses they incur, which could be material.
If we are unable to obtain a sufficient supply of components, or if we experience any interruption in the supply of components, our product shipments could be reduced or delayed or our cost of obtaining these components may increase. Component shortages and delays affect our ability to meet scheduled product deliveries, damage our brand and reputation in the market, and cause us to lose sales and market share. For example, component shortages and disruptions in supply related to the COVID-19 induced lockdowns in Shenzhen, China and Shanghai, China previously had limited our ability to supply all the worldwide demand for our NETGEAR for Business switch products, and our revenue and profitability was affected. At times we have elected to purchase components on the spot market or to use more expensive transportation methods, such as air freight, to make up for manufacturing delays caused by component shortages, which reduces our margins.
Some of our competitors have substantially greater resources than we do, and to be competitive we may be required to lower our prices or increase our sales and marketing expenses, which could result in reduced margins or loss of market share and revenue.
We compete in a rapidly evolving and fiercely competitive market, and we expect competition to continue to be intense, including price competition. Our principal competitors in the consumer market include ARRIS, ASUS, D-Link, Eero (owned by Amazon), Linksys (owned by Foxconn), Google WiFi, and TP-Link. Our principal competitors in the business market include Arista, Cisco Systems, D-Link, Extreme Networks, Fortinet, Hewlett-Packard Enterprise, Juniper Mist, Ruckus Networks, TP-Link, and Ubiquiti. Our principal competitors in the service provider market include Cradlepoint, Franklin, Huawei, Inseego, Nokia, Orbic, Sonim, TP-Link, WNC, and ZTE. Other competitors include numerous local vendors such as Xiaomi in China, AVM in Germany and Buffalo in Japan. In addition, these local vendors may target markets outside of their local regions and may increasingly compete with us in other regions worldwide. Our potential competitors also include other consumer electronics vendors, including Apple, LG Electronics, Microsoft, Panasonic, Sony, Toshiba and Vizio, who could integrate networking and streaming capabilities into their line of products, such as televisions, set top boxes and gaming consoles, and our channel customers who may decide to offer self-branded networking products. We also face competition from service providers who may bundle a free networking device with their broadband service offering, which would reduce our sales if we were not the supplier of choice to those service providers. In the service provider space, we also face significant and increased competition from original design manufacturers, or ODMs, and contract manufacturers who sell and attempt to sell their products directly to service providers around the world.
Many of our existing and potential competitors have longer operating histories, greater name recognition and substantially greater financial, technical, sales, marketing and other resources. These competitors may, among other things, undertake more extensive marketing campaigns, adopt more aggressive pricing policies, obtain more favorable pricing from suppliers and manufacturers, and exert more influence on sales channels than we can. Certain of our significant competitors also serve as key sales and marketing channels for our products, potentially giving these competitors a marketplace advantage based on their knowledge of our business activities and/or their ability to negatively influence our sales opportunities. For example, Amazon
