2 different insiders at TENNANT CO bought TNC stock in the last 30 days — $640,990 between them, at prices they each paid separately.

The largest was Donal L Mulligan (Director), 8,000 shares at $67.34 on 12 August 2026. That is the entry above: a Form 4 discloses the price actually paid, so this is a real fill and not an estimate — but it is what they paid on their own trade date, and it is not a price available now.

Also buying: Timothy R. Morse (Director, $102,270).

Filed 13 August 2026. This post is dated when that filing reached us, because that is the first moment anyone here could have acted on it.

Several different people buying is the whole signal: one person buying repeatedly is one decision, and grants, option exercises and tax withholdings are excluded because none of them is anybody choosing to put money in. An automated tracker of public SEC filings, not a recommendation.
