[SCHEDULE 13G/A] The AZEK Company Inc. SEC Filing

Rhea-AI Filing Summary

The Vanguard Group has filed Amendment No. 4 to its Schedule 13G for Datadog, Inc. (DDOG) covering holdings as of 30 June 2025. The filing discloses that Vanguard, acting as an investment adviser (Rule 13d-1(b)), now beneficially owns 32,153,371 shares of Datadog’s Class A common stock, representing 10.06 % of the outstanding class.

Voting vs. dispositive authority

• Sole voting power: 0 shares
• Shared voting power: 245,155 shares
• Sole dispositive power: 31,311,230 shares
• Shared dispositive power: 842,141 shares

Vanguard therefore controls disposition of the vast majority of its position but exerts minimal voting influence, consistent with passive index-tracking strategies.

The amendment was triggered by Vanguard’s ownership exceeding the 10 % threshold, requiring an updated 13G. Vanguard affirms the shares were acquired in the ordinary course of business and not to influence control of Datadog. Clients of Vanguard—including registered investment companies and managed accounts—ultimately benefit from dividends and sale proceeds, with no single client holding more than 5 % of the class.

Key take-aways for investors

• Institutional ownership of just over 10 % provides a supportive shareholder base and may enhance share liquidity.
• Limited voting power suggests Vanguard remains a passive holder, reducing immediate governance impact.

Positive

• Institutional support: Vanguard’s 10.06 % stake signals confidence from a top-tier asset manager, potentially enhancing market perception and liquidity.

Negative

• None.

Insights

Equity Portfolio Manager

TL;DR: Vanguard crosses 10 % ownership in DDOG, signalling passive institutional support but little governance influence.

Vanguard’s 32.15 million-share stake places it among Datadog’s largest holders. The 10.06 % stake can improve liquidity and broaden analyst coverage, potentially supporting valuation multiples. However, the absence of sole voting power (0 shares) confirms a strictly passive posture; hence, corporate strategy will remain unaffected. From a portfolio perspective, the filing is neutral-to-modestly positive: it underscores institutional confidence without introducing activist risk. Impact on near-term price action is typically limited unless the market was unaware Vanguard had already neared the 10 % mark.

Corporate Governance Analyst

TL;DR: Vanguard gains >10 % but retains passive 13G status—low governance impact.

Crossing the 10 % threshold often raises control-related questions, yet Vanguard’s certification under Rule 13d-1(b) and zero sole voting rights mitigate such concerns. Dispositive authority over ~31.3 million shares grants exit flexibility; rapid sales could pressure the stock, but Vanguard historically maintains disciplined rebalancing. No other entity has a >5 % indirect interest, reducing complexity of ownership. Overall governance implications are minimal, making the disclosure largely informational for investors.
