Rhea-AI Filing Summary

Performance Stock Units financial

"The performance units are subject to vesting over three years with one third"

Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.

restricted stock units financial

"The restricted stock units are subject to vesting over three years"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Dividend Equivalent Units financial

"The dividend equivalent units will vest proportionately with the underlying restricted stock units"

Dividend equivalent units are bookkeeping credits that mirror cash dividends paid on actual shares, granted to holders of stock-based awards such as restricted stock units or deferred compensation. They matter to investors because they increase a company’s reported employee compensation cost and can lead to issuance of more shares or cash payouts over time, similar to extra pay linked to ownership that affects shareholder dilution and corporate cash flow.

tax-withholding disposition financial

"transaction_action": "tax-withholding disposition""

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

FAQ

What did ACIC officer Brooke Adler report in this Form 4?

Brooke Adler reported exercising several equity awards into AMERICAN COASTAL INSURANCE Corp common stock and a related tax-withholding share disposal. These are compensation-driven transactions, not open-market buying or selling of shares.

How many ACIC shares were used for tax withholding in Brooke Adler’s filing?

The filing shows a disposal of 5,935 shares of AMERICAN COASTAL INSURANCE Corp common stock at $11.65 per share. This is classified as a tax-withholding disposition to cover exercise price or tax liabilities on vested awards, not an open-market sale.

What types of equity awards did Brooke Adler exercise at ACIC?

Brooke Adler exercised performance stock units, restricted stock units, and associated dividend equivalent units, each convertible into common shares. These awards carried a stated exercise or conversion price of $0.00, so they functioned as stock-based compensation rather than cash-funded purchases.

Were Brooke Adler’s ACIC transactions open-market buys or sells?

No open-market buys or sells are shown. The filing records derivative exercises converting awards into common stock and one F-code tax-withholding disposition, where shares were withheld to satisfy obligations. These events are routine for equity compensation programs, not discretionary trading.

How do dividend equivalent units work in ACIC officer compensation?

Dividend equivalent units mirror dividends on underlying stock units. The filing states these units vest proportionately with related restricted or performance stock units, then convert into common shares. They provide additional share-based compensation aligned with dividend payments, without separate cash dividend receipts.
