Supply chain data reveals the business relationships between companies and allows you to analyze the capital flow between companies on both a customer (revenue) and supplier (cost) basis. Generally, supply chain data for public companies can be found in a variety of sources such as public filings (including annual and other periodic reports), conference call transcripts, capital markets presentations, sell-side conferences, company press releases, company websites, and industry insiders.
Typically, supply chain data is incomplete due to the fact that SEC Regulation S-K requires companies to disclose only supply-chain relationships for customers that provide revenues greater than 10% on an annual basis. Additionally, information on international suppliers and customers is difficult to identify.
To find supply chain data, you can use either Bloomberg or Capital IQ to get a holistic view of the supply chain structure for a particular company of interest.
Bloomberg covers supply chain relationship for over 35,000 companies and the data is updated regularly. To display supply chain analysis in Bloomberg, type the mnemonic SPLC. Please note that SPLC function can only be used together with an equity. For example, to find Apple’s supply chain information, type:
AAPL < EQUITY > SPLC < GO>
You can sort the data by suppliers and customers and display the results in a table format. For example, you can view the suppliers list like the following:
Similarly, Capital IQ also presents supply chain data under the “business relationships” category. Additionally, Capital IQ provides the sources for the data.
