TOMZ Corporation (TOMZ) is a small-cap company engaged in precision manufacturing, primarily for aerospace and medical sectors. Financial screening reveals strong compliance with key ratio thresholds across AAOIFI, MSCI, and S&P standards, with low debt and minimal non-compliant income. However, involvement in defense components introduces potential Shariah concerns, classified as questionable activity requiring monitoring. The company is not included in any major Shariah indices due to its micro-cap status and liquidity constraints, despite passing compliance screens. Overall, while ratios support investability with purification, business activity scrutiny and index exclusion warrant caution for Shariah-conscious investors.
