sell to cover financial

"sold pursuant to a sell to cover transaction to satisfy tax withholding obligations"

Sell to cover is when a person who receives company stock through options or awards sells just enough shares immediately to pay required taxes, exercise costs, or fees, keeping the rest. Think of it like cashing part of a bonus to cover the tax bill so you can keep the remainder. For investors, it can create predictable small selling pressure and slightly change the number of shares actually held by insiders without increasing long‑term dilution.

weighted average price financial

"The price reported is a weighted average price."

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.

American Depositary Shares financial

"All of the Class A American Depositary Shares ("ADSs") were sold"

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

block trades financial

"These ADSs were sold as part of block trades by the broker"

A block trade is a single, large buy or sell of shares or bonds arranged privately between big traders rather than piecemeal on the public market. Think of it like buying a whole shipment at once instead of many small shopping trips; it lets large holders move big positions with less immediate disruption but can signal strong buying or selling pressure and cause price swings once the trade is known, so investors watch block trades for clues about market sentiment and liquidity.
