A Form 4 is filed within two business days of a company insider — an officer, a director, or a holder of more than ten percent of the stock — changing their position in the shares. All 7 filings in this group are Form 4s for Achieve Life Sciences, Inc.
The difficulty with reading these filings as a group is that a single form type covers transactions that mean entirely different things. An executive spending their own money to buy stock and an executive having shares withheld to pay tax on a vesting grant both appear as a Form 4. Every filing below is therefore tagged with the nature of the underlying transaction, taken from the transaction code reported on the form itself.
Across the 7 insider filings shown, the breakdown is 6 compensation award and 1 open-market sale. 1 of them involved a discretionary open-market trade; the rest are compensation and administrative mechanics.

ACHV insider Form 4 filed for equity award, exercise, or tax withholding
Halladay Benjamin (Chief Financial Officer) filed a Form 4 covering compensation-related activity such as stock awards, option exercises, conversions, or tax withholding. These filings are usually neutral.
Shares were granted as compensation rather than purchased. No cash changed hands, so the filing reflects a pay decision by the company, not a judgement about the price.

ACHV insider Stewart Richard Alistair (Director) sold 20,626 shares (~$175.2K)
Stewart Richard Alistair, listed as Director at ACHIEVE LIFE SCIENCES, INC., reported an open-market sale of 20,626 ACHV shares in a Form 4 filing. This is a confirmed insider sale, not just a proposed sale notice.
The insider sold shares on the open market. Sales may be discretionary or executed automatically under a pre-arranged Rule 10b5-1 trading plan, and a Form 4 does not always make clear which applies.
