Insights

Securities Analyst

TL;DR: T. Rowe Price discloses a material 16.5% passive stake in LSCC with concentrated sole voting and dispositive power.

The disclosure confirms that an institutional investment adviser holds a substantial position in Lattice Semiconductor: 22,712,142 shares equal to 16.5% of the class, with nearly identical sole voting and dispositive power figures reported. That concentration is material to holders because it signals a significant institutional ownership block. The filing is made under Schedule 13G-style assertions that the position is held in the ordinary course and not for control. The statement that the adviser denies beneficial ownership for purposes beyond advisory duties is consistent with a passive, advisory-managed position. Investors should note the specific fund-level holding of 8,192,600 shares (6.0%), which is disclosed separately.

Corporate Governance Expert

TL;DR: A 16.5% holding with sole voting/dispositive powers is notable; filer asserts no intent to exercise control.

The filing documents concentrated ownership metrics: sole voting power of 22,661,195 shares and sole dispositive power of 22,712,142 shares. The separate identification of the Mid-Cap Growth Fund owning 8,192,600 shares (6.0%) provides additional granularity on client-level exposure. The filer expressly states the securities are not held to influence control and disclaims beneficial ownership beyond its advisory function, consistent with Schedule 13G reporting. From a governance perspective, the position's size is material, though the filing frames it as passive rather than an active governance campaign.
