Form 4 raw → Raspberry
The value is in what we do not call a signal.
The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

The sale of shares reported on this Form 4 was effected to cover the taxes due upon the reporting person's exercise of a stock option expiring in the near term, with the reporting person retaining the net shares. Reflects the weighted average price of 3,156 shares of common stock of Tennant Company sold by the reporting person in multiple transactions on February 27, 2026 with sale prices ranging from $61.40 to $61.46 per share. The reporting person undertakes to provide upon request by the U.S. Securities and Exchange Commission staff, the issuer, or a security holder of the issuer, full information regarding the number of shares sold at each separate price. Fully vested.
Raspberry interpretation
Informational — no alert
Reason: tax_withholding. The filing footnotes identify tax withholding.
Recent transactions
Voluntary purchases and sales; administrative noise stays hidden.
