Merck & Company, Inc.

Based on reviewing Merck's product portfolio and revenue streams through their SEC filings and investor relations materials, the company's primary revenue sources come from pharmaceutical products, vaccines, and animal health products. None of these categories constitute haram activities. The company does not derive revenue from alcohol, gambling, pork products, or other prohibited items.

Analysis of Merck's financial statements for the past four quarters shows no material interest income or interest expense relative to their total revenue and expenses. The company's operations are primarily funded through business activities rather than interest-bearing debt or interest-generating investments.

Based on review of public information and SEC filings, Merck maintains operations in various countries but there is no evidence of material ongoing collaboration with entities involved in human rights violations. While the company does business in China, there is no clear evidence of direct collaboration with the Chinese Communist Party. There is also no evidence of current R&D centers or ongoing projects in Israel.
