Impact Evaluation

• Market Cap Context: The transaction value of ~$11k is negligible compared to Post Holdings' $5.75 billion market capitalization.
• Ownership Concentration: The director's total holdings remain a very small fraction (0.011%) of the total shares outstanding.
• Dilution Impact: The grant of 106.907 stock equivalents has a de minimis dilutive effect on the 54.3 million shares outstanding.
• Transaction Significance: The transaction is classified as low significance due to its small value and its nature as a routine compensation grant rather than an open-market trade.

Additional Context

Transaction Notes

• Special Circumstances: Per Footnote 1, this transaction represents a director's retainer deferred into stock equivalents under the company's Deferred Compensation Plan. These are settled in cash upon separation from the board, not in common stock.
