Donaldson Company, Inc. (symbol: DCI) primarily sells its products and solutions to other companies (Business-to-Business or B2B) rather than directly to individuals.

According to its public filings, Donaldson has a highly diversified customer base and does not have any single customer that accounts for 10% or more of its consolidated net sales. Therefore, there are no specific "major customer companies" that can be individually named. Instead, its customer base can be broadly categorized by the types of businesses it serves:

• Original Equipment Manufacturers (OEMs): These are companies across various industries that integrate Donaldson's filtration, exhaust, and acoustic products into their own manufactured equipment. This includes manufacturers of heavy-duty trucks, construction equipment, agricultural machinery, mining equipment, industrial compressors, aerospace components, and power generation systems. Donaldson's products become integral components of the final products sold by these OEMs.
• Aftermarket Distributors and Dealers: This vast network of channel partners resells Donaldson's replacement filters and parts to end-users for maintenance, repair, and overhaul (MRO) of existing equipment. These distributors and dealers serve a wide range of industries globally, ensuring the ongoing availability and servicing of Donaldson products throughout their lifecycle.
• Industrial End-Users: Businesses in sectors such as manufacturing, food and beverage, pharmaceuticals, metals and mining, chemical processing, and other general industrial applications directly purchase Donaldson's industrial filtration systems (e.g., for dust, fume, mist collection, process filtration, compressed air purification) to improve air quality, protect processes, and comply with environmental regulations within their operational facilities.

The global shift towards the electrification of vehicles and heavy equipment poses a significant emerging threat to Donaldson's core business, particularly its Engine Products segment. As manufacturers of commercial vehicles, off-road equipment, and other machinery increasingly adopt electric powertrains, the demand for traditional air, fuel, and lube filters associated with internal combustion engines is expected to decline over the long term. This trend, evidenced by substantial investments in electric vehicle development by major original equipment manufacturers (OEMs) and supportive government policies worldwide, represents a fundamental technological disruption to a key market for Donaldson's legacy filtration products.
