02:27 PM EDT, 09/16/2025 (MT Newswires) -- Thomson Reuters ( TMSOF ) said that it purchased Additive, a start-up in San Francisco which was founded in 2023, that has succeeded in leveraging AI to automate data capture from tax-related documents like Schedule K-1 federal tax forms which are complex and unstructured, notes National Bank.

The tuck-in purchase involves limited revenue and will be negligibly dilutive to margins. That said, it comes with a talented workforce who will continue to contribute to TRI's innovation efforts, as the company expands its tax workflow automation capabilities, writes analyst Adam Shine.

Thomson Reuters ( TMSOF ) is rated Outperform, with a $300 target.
