[Form 4] The AZEK Company Inc. Insider Trading Activity

Rhea-AI Filing Summary

AZEK – Form 4 (07/02/2025) documents the disposition of all AZEK equity held by Chief Human Resources Officer Sandra Lamartine in connection with the closing of the previously announced merger with James Hardie Industries plc (JHX) on 07/01/2025.

• Common shares: 21,015 Class A shares were reported as disposed (Code “D”).
• Equity awards: 42,262 performance-based RSUs and 33,339 stock-option awards (exercise prices ranging from $20.18 to $53.51) were likewise disposed of and converted into JHX instruments.

The filing reiterates final merger economics:

• Cash Consideration: $26.45 per AZEK share.
• Share Exchange Ratio: 1.0340 JHX ordinary shares per AZEK share.
• Fractional shares settled in cash based on JHX’s 5-day VWAP of $26.053018.

All AZEK awards were assumed by JHX and converted into equivalent JHX restricted-stock, performance-unit or option awards using the same vesting schedules. Following conversion, the reporting person holds 0 AZEK securities; future ownership, if any, will be in JHX.

This Form 4 provides transactional confirmation that the merger closed and that AZEK equity has been fully exchanged, giving investors definitive consideration details and eliminating standalone AZEK insider ownership.

Positive

• Merger consummation confirmed, removing deal-completion risk for investors.
• Clear consideration terms: $26.45 cash + 1.0340 JHX shares per AZEK share.
• Employee equity preserved via 1-for-1 conversion to JHX instruments, supporting retention.

Negative

• AZEK insider ownership reduced to zero, eliminating a traditional alignment signal with the legacy entity.

Insights

M&A Specialist

TL;DR – Filing confirms merger closing and exact payout terms.

The Form 4 is a mechanical but important post-closing record. It shows that AZEK share conversion is complete: each share yielded $26.45 cash plus 1.0340 JHX shares. Insider disposition code “D” is purely transactional, not indicative of voluntary selling. Equity awards were rolled into equivalent JHX instruments, preserving vesting and reducing employee flight risk. From an M&A perspective, this removes execution risk—consideration terms are now locked. The document thus validates the deal close, a key milestone for arbitrage investors.

Portfolio Manager

TL;DR – Confirms liquidity event; AZEK equity ceases to exist.

For holders of AZEK, the filing signals that their value realization is now in cash and JHX stock. The fixed cash component delivers immediate liquidity, while the share portion transfers exposure to JHX’s fundamentals. Insider ownership of AZEK drops to zero, eliminating an alignment metric, but award rollover suggests continuity in the combined firm’s leadership incentives. Market impact is modest because terms were pre-announced, yet confirmation reduces residual uncertainty and may prompt final index and portfolio rebalancing.
