[SiteOne Landscape Supply](https://www.bullished.co/tag/site/) CEO Doug Black bought [9,100 shares](https://www.sec.gov/Archives/edgar/data/0001672083/000110465926122247/xslF345X06/tm2628894-2%5F4seq1.xml?ref=bullished.co) of the company's stock on Friday at an average of $110.30, a purchase worth about $1.0 million, according to a [Form 4](https://www.bullished.co/learn/insider-selling-meaning/), the report insiders file after trading. It is his third purchase filing since August.

## Two trusts, two prices

The shares were split evenly between two family trusts. The 2021 Family Trust bought 4,550 shares at $109.91, and the 2019 Family Trust bought 4,550 at $110.68\. Both were open-market purchases held indirectly.

One trust is run by Black as trustee. The other is run by his spouse, according to the filing's footnotes.

Black now holds 611,527 shares as reported on the filing: 482,161 directly and 129,366 indirectly through family trusts. That is worth about $68.3 million at Tuesday's close of $111.71, above his average purchase price. This purchase equals 1.49% of his post-filing stake.

## Buying as the stock slides

Two earlier filings show Black bought 8,000 shares on August 4 at about $102.03 ($816,000) and 5,000 shares on August 26 at about $96.13 ($481,000). Together those came to 13,000 shares, or $1.3 million.

Including Friday's trade, the three filings since August 5 total 22,100 shares, or $2.3 million. The stock has fallen about 8% this year as of Monday's close.
