Restricted Stock financial

"Represents the number of shares of Restricted Stock awarded for current year."

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

What insider transactions did MSEX executive Robert K. Fullagar report?

Robert K. Fullagar reported a grant of 2,128 restricted shares, vesting of 886 previously awarded restricted shares, and surrender of 394 shares to cover taxes. These are compensation-related and tax-withholding entries, not open‑market stock purchases or sales.

How many Middlesex Water (MSEX) shares were granted to the executive?

He was granted 2,128 shares of restricted common stock at a reference price of $52.05 per share. This award represents current-year equity compensation rather than an open‑market purchase, aligning his incentives with long‑term shareholder interests through stock-based pay.

Why were 394 MSEX shares surrendered in this Form 4 filing?

The 394 Middlesex Water shares were surrendered back to the issuer to satisfy tax withholding obligations from restricted stock vesting. This F‑code disposition is a standard tax payment mechanism and does not represent an open‑market sale or discretionary reduction of ownership.

What does the vesting of 886 restricted MSEX shares mean for the executive?

Vesting of 886 restricted shares means previously granted stock became fully owned and no longer subject to forfeiture conditions. It converts long‑term incentive awards into directly held shares, reflecting time or performance conditions being met under the company’s equity compensation plan.

How many Middlesex Water (MSEX) shares does the executive directly hold after these transactions?

After these transactions, the executive’s direct holdings include multiple components: 7,319 restricted stock shares after the new award, 6,433 restricted shares after vesting, 1,297 book‑entry common shares, plus positions in a dividend reinvestment plan and street‑name accounts.
