[144] Western Alliance Bancorporation SEC Filing

Rhea-AI Filing Summary

MillerKnoll, Inc. (MLKN) – Form 4 filing for Chief Strategy & Technology Officer Megan C. Lyon, dated 07/24/2025.

On 07/22/2025 Lyon converted 35,376 restricted stock units (RSUs) into common shares (Transaction Code “M”) at a stated price of $0.00, increasing her direct common-stock holdings to 74,371.33 shares immediately after the conversions. To satisfy withholding obligations, she disposed of 10,499.198 shares at $19.50 per share (Transaction Code “F”), leaving 63,872.13 shares held directly.

Following the transactions, Lyon retains 53,931 unvested RSUs (down from 59,176). Of these, 30,131 RSUs represent her fiscal 2024 annual incentive bonus (cliff-vest 07/22/2025) and 5,245 RSUs follow a 33%/33%/34% annual vest schedule through 2027.

Net result: Lyon’s equity exposure increased by ~24.9 k shares; all sales were automatic tax-withholding sales rather than open-market disposals. No other insider or company-level financial data is included.

Positive

• Net acquisition of approximately 24,877 common shares by a C-suite executive increases insider ownership and aligns incentives.

Negative

• Disposition of 10,499 shares at $19.50 (tax-withholding) represents dilution of the initial RSU conversion, though routine.

Insights

Equity Compensation Analyst

TL;DR: Executive net adds 24.9 k MLKN shares; disposals were tax-withholding—impact neutral.

The Form 4 shows standard RSU settlement activity. Lyon converted 35,376 RSUs, then sold 10,499 shares to cover taxes at $19.50, a routine price-and-sell mechanism set by the company. Her direct ownership rose 64% to 63,872 shares, signalling continued alignment with shareholders. RSU balance declines appropriately to 53,931, maintaining long-term incentives. Because no discretionary market sale occurred, the filing does not suggest bearish insider sentiment. Material impact on MLKN’s float is de minimis.

Portfolio Risk Manager

TL;DR: Routine compensation settlement; no valuation signal, not market-moving.

Transaction codes “M” and “F” indicate option/RSU conversion and tax-withholding sell-to-cover, respectively. The $205 k gross market value sold (10,499 × $19.50) is immaterial versus MLKN’s average daily volume, so liquidity or sentiment impact is negligible. Net share accumulation by a C-suite member can be viewed as slightly reassuring, yet lacks predictive power absent open-market buys. I classify the disclosure as non-impactful from a risk-assessment standpoint.
