Rule 10b5-1 trading plan regulatory

"The sale reported on this Form 4 was effected pursuant to a Rule 10b5-1 trading plan adopted March 4, 2026."

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.

grantor retained annuity trust financial

"100% of the limited liability company interest is owned by a grantor retained annuity trust, of which the Reporting Person is the annuitant and the trustee."

A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.

Stock Option (right to buy) financial

"Stock Option (right to buy) with an exercise or conversion price of 5.3500 per share."

annuitant financial

"the limited liability company interest is owned by a grantor retained annuity trust, of which the Reporting Person is the annuitant and the trustee."

indirect ownership financial

"Shares are held by ALG 2025 GRAT HOLDINGS LLC, indicating indirect ownership through this entity."
