Lattice Semiconductor (LSCC) SVP Desale sells 2,039 shares under 10b5-1 plan

Rhea-AI Filing Summary

Lattice Semiconductor senior vice president of R&D Pravin Desale reported an open-market sale of 2,039 shares of common stock at $142.89 per share. After this trade, he directly holds 73,519 shares.

Separately, 868 shares were withheld by the company at $142.86 per share to cover tax obligations tied to the vesting of restricted stock units, which is not an open-market sale. The open-market transaction was carried out under an approved Rule 10b5-1 trading plan, indicating it was pre-scheduled rather than opportunistic.

Insights

Equity compensation and insider-trading analyst

Routine sale and tax withholding, small relative to remaining holdings.

SVP R&D Pravin Desale sold 2,039 shares of Lattice Semiconductor common stock at $142.89 per share in an open-market transaction. He still directly owns 73,519 shares, so the sale represents a modest portion of his position.

An additional 868 shares were surrendered at $142.86 per share to satisfy tax withholding from restricted stock unit vesting, which is a mechanical, non-market event. The filing notes the sale occurred under an approved Rule 10b5-1 plan, suggesting the timing was pre-arranged rather than reactive.

Given the pre-planned nature and limited size relative to remaining holdings, this activity looks like routine portfolio and tax management rather than a major shift in insider sentiment. Subsequent filings may provide further context if larger or more frequent trades appear over time.

Rule 10b5-1 regulatory

"The transaction indicated was conducted under an approved 10b5-1 Plan"

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.

restricted stock units financial

"in connection with the vesting of an installment of the restricted stock units"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

tax withholding obligations financial

"retained by the Issuer in order to meet the tax withholding obligations of the Reporting Person"

open-market sale financial

"transaction_action": "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

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.
