Insights

Routine RSU tax withholding; no open-market selling signal.

The filing shows Sheela Kosaraju, SVP and General Counsel of Ciena Corp, had 2,013 common shares withheld at $428.22 per share. All entries use code F, defined as payment of tax liabilities by delivering securities.

Footnotes explain each withholding relates to prior restricted stock unit awards granted between 2022 and 2025. This is a mechanical step when RSUs vest and does not represent discretionary buying or selling in the market.

Following these transactions, Kosaraju holds 91,943 common shares directly, including unvested RSUs and PSUs. The pattern is consistent with standard executive equity compensation practices and does not materially change her overall equity exposure as shown in this filing.

Restricted Stock Units (RSUs) financial
"Represents shares withheld to cover payment of the tax liabilities of the reporting person related to a restricted stock unit (RSU) award agreement dated 12/13/2022."
Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.
Performance Stock Units (PSUs) financial
"Shares reported include unvested Restricted Stock Units (RSUs) and Performance Stock Units (PSUs)."
Performance stock units (PSUs) are a form of executive or employee pay that promise company shares only if pre-set performance goals are met over a defined period; think of them as a bonus paid in stock that arrives only when the company hits agreed targets. Investors watch PSUs because they affect the number of shares outstanding (dilution) and reveal how management’s pay is tied to financial or operational results, aligning incentives with shareholder outcomes.
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.
Form 4 regulatory
"Acquisition of the RSU was previously reported in Table I of the reporting person's Form 4 filed on 12/14/2023."
Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
Common Stock financial
"security_title: "Common Stock""
Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
