RSUs financial

"in connection with the vesting and settlement of the RSUs."

RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.

statutory tax withholding obligations financial

"to cover the statutory tax withholding obligations in connection with the vesting"

sell to cover financial

"to be funded by a "sell to cover" transaction and does not represent"

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 in Column 4 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.

What did Bicycle Therapeutics (BCYC) CFO Travis Thompson report in this Form 4?

Travis Thompson reported sales of Bicycle Therapeutics ordinary shares tied to RSU vesting. The transactions were required "sell to cover" sales for statutory tax withholding, rather than discretionary open-market selling, and were reported as involving a total of 901 shares across two dates.

How many Bicycle Therapeutics shares did the CFO sell and at what prices?

The CFO reported selling 901 ordinary shares in total. He sold 799 shares at a weighted average of $4.91, from trades between $4.88 and $4.98, and 102 shares at $5.05, according to the Form 4 details and accompanying footnotes.

Why were Travis Thompson’s Bicycle Therapeutics share sales executed?

The Form 4 footnotes state the sales were required to satisfy statutory tax withholding obligations related to RSU vesting.

How many Bicycle Therapeutics shares does the CFO hold after these transactions?

After the reported tax-related sales, the CFO directly holds 65,364 ordinary shares of Bicycle Therapeutics. This remaining position substantially exceeds the 901 shares sold, indicating the transactions affected only a small portion of his overall direct share ownership as shown in the filing.

Were Travis Thompson’s Bicycle Therapeutics share sales open-market trades?

The transactions are coded as open-market sales, but the footnotes clarify they were mandated "sell to cover" sales. They were executed to fund minimum statutory tax withholding on RSU vesting, and the filing notes they do not represent discretionary sales by the reporting person.
