PTC

After reviewing PTC's business model and revenue sources, their income primarily comes from software licenses, subscriptions, and support services for industrial and manufacturing applications. These core revenue streams involve legitimate business activities that create real value through technology solutions. There is no evidence of revenue from prohibited sources like gambling, alcohol, tobacco, or other haram activities.

Based on the financial data from the last four quarters, PTC has interest expenses but they are primarily related to operational financing and corporate debt. The interest expense ratios relative to total expenses have remained within acceptable levels. While the company has interest-bearing debt, it is not a core part of their business model or revenue generation.

While PTC maintains global operations, there is no evidence of significant direct collaboration with entities involved in human rights violations. The company's business relationships appear to be primarily with industrial and manufacturing clients worldwide through normal business operations.
