[144] SiTime Corporation SEC Filing

Rhea-AI Filing Summary

SiTime Corporation (SITM) Form 144 notice shows a proposed sale of 6,443 shares of common stock through Stifel Nicolaus with an aggregate market value of $1,575,764.00, scheduled approximately for 09/09/2025 on NASDAQ. The filing identifies the securities were acquired as restricted stock units (RSUs) from the issuer on 05/20/2024 (3,415 shares) and 08/20/2024 (3,028 shares). There are 23,600,000 shares outstanding reported in the notice, so the planned sale represents a small fraction of the outstanding share count. The filer states no securities of the issuer were sold by the person in the past three months and includes the standard representation about no undisclosed material nonpublic information.

• Source of shares disclosed (RSUs with acquisition dates) which clarifies insider holdings
• No sales in past three months reported for the seller in this filing

Negative

• An insider intends to sell 6,443 shares, which may be perceived negatively by some investors
• No 10b5-1 plan date or trading plan is indicated in this notice, leaving timing rationale unspecified

Insights

Securities Analyst

TL;DR: Insiders disclosed a small proposed sale of RSU-derived shares, offering transparency but likely immaterial to valuation.

The filing shows an insider intends to sell 6,443 common shares acquired as RSUs in 2024 through a broker on NASDAQ with aggregate market value of $1,575,764.00. Given the stated 23.6 million shares outstanding, the proposed disposition is a negligible portion of the float (approximately 0.03%). There is no record in this notice of prior sales in the past three months by this person. For investors, this is routine insider liquidity rather than a material change to capital structure or corporate outlook.

Corporate Governance Expert

TL;DR: Proper Rule 144 disclosure completed; transaction appears consistent with routine executive RSU vesting and liquidity.

The form provides required information about the source of the securities (RSUs granted by the issuer) and certifies absence of undisclosed material information. The scheduled sale through Stifel Nicolaus and the explicit acquisition dates supply the transparency regulators and investors expect. There is no evidence in this notice of any trading plan date or 10b5-1 adoption referenced, and no sales in the prior three months are reported, which reduces complexity around aggregation rules. Overall, this is a customary insider filing complying with disclosure norms.
