Diana Shipping reduces Genco stake to 5.47% after 1.52M-share sale

Diana Shipping Inc. reports holding 2.38 million GNK shares, or about 5.47% of Genco’s common stock, after significant recent share sales including a large block trade.

Rhea-AI Filing Summary

GENCO SHIPPING & TRADING LTD (GNK) has an updated ownership report from Diana Shipping Inc., which now may be deemed to beneficially own 2,383,585 common shares, representing approximately 5.47% of Genco’s outstanding common stock. Diana Shipping has sole voting and sole dispositive power over all of these shares.

The ownership percentage is calculated using 43,586,605 Genco common shares outstanding as of August 5, 2026. Recent activity includes multiple open‑market sales and a block sale of 1,522,000 shares at $26.75 on September 8, 2026, which reduced Diana Shipping’s position to its current level.

Filing Explained

Diana’s reported stake remains 5.47% with sole voting and dispositive power; the percentage uses Genco’s August 5 share count.

This amendment records completed sales from August 27 through September 8, 2026 and leaves Diana Shipping with 2,383,585 shares, or 5.47%; it retains sole voting and dispositive power over that stake.

The structural change is to Diana's ownership and control rights: the filing reports sales by the holder, while Diana continues to have sole authority to vote and dispose of the reported shares.

The schedule covers open-market sales on August 27, August 28, and September 1 through September 4. Those prices are reported as averages from multiple transactions; the September 8 block sale is reported at $26.75.

Item 5(a) bases the 5.47% figure on 43,586,605 Genco shares outstanding as of August 5, 2026, so the stated percentage is tied to that earlier share-count date.

5 terms

beneficially own financial

"may be deemed to beneficially own 2,383,585 Shares"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

sole voting power financial

"The Reporting Person has sole voting power and sole dispositive power"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

sole dispositive power financial

"The Reporting Person has sole voting power and sole dispositive power"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

block sale financial

"September 8, 2026 Block Sale 1,522,000 $ 26.75"

A block sale is a single large transaction in which a big shareholder or investor sells a substantial number of a company's shares at once, often arranged privately to avoid pushing the market price up or down. It matters to investors because such a concentrated sale can change who controls or influences a company, temporarily affect the stock’s price and liquidity, and may signal how large holders view the company’s outlook — like one person unloading a truckload of goods can move the local market.

open market sales financial

"August 27, 2026 Open Market Sales 8,427 $ 26.13"
