The following ranking presents the current top list of the world’s leading EMS and ODM companies, as determined by in4ma in collaboration with EMSNOW.

Explanation:

Over 120 companies were considered in compiling our list of 100 companies, including 71 publicly traded and 49 private companies. For publicly traded companies, the figures are based on published data. Thirteen companies (as of March 5, 2026) have not yet released their final results for 2025; in these cases, the most recent annual forecasts communicated by management were used. These companies account for 12.3% of total revenue in 2025. Even with a 20% deviation, this would only affect the total value by approximately ±2.5%.

Of the 49 unlisted companies, no current data was available for 20 companies, so estimates were made based on older figures. As these are predominantly smaller companies, they account for only 1.3% of total revenue. Even with a possible deviation of 50%, this would only lead to an additional uncertainty of approximately ±0.65%.
Overall, this results in an estimated total tolerance of ±3.1% for the valuation.
