Insights

CFO sells 60,000 Aura Minerals shares under pre-set 10b5-1 plan.

The CFO of Aura Minerals Inc. executed open-market sales totaling 60,000 Common Shares of AUGO on June 30, 2026. The prices ranged around the low‑$60 level, with each line reported using a weighted average price.

Because the sales were made pursuant to a pre‑arranged Rule 10b5-1 trading plan adopted on March 19, 2026, the timing is more mechanical than discretionary. The filing also shows the CFO retaining a six‑figure share position, suggesting these are partial liquidity moves rather than an exit.

3 terms

Rule 10b5-1 trading plan regulatory

"The sales reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average price financial

"The price reported is a weighted average price. These shares were sold in multiple transactions"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

Common Shares financial

"security_title: Common Shares, transaction_type: non-derivative"

Common shares are the basic units of ownership in a company that give holders a claim on profits and a right to vote on key matters, like electing the board. Think of them as membership cards in a club: they let you share in successes and losses, but in a bankruptcy or liquidation they are paid after creditors and preferred shareholders, so their value can swing more and matters for assessing risk and potential return.
