Alfred Lumsdaine, chief financial officer of Ardent Health, Inc. (ARDT), surrendered 3,389 company shares to cover tax withholding on September 25, 2026, according to a Form 4 disclosure reported by the SEC. The transaction carried a reported price of $10.54 per share and a rounded value of $35,720.

The transaction was identified as a surrender for tax withholding. That distinction separates it from an executive placing shares for sale in the stock market. The disclosure records shares being used to meet a tax obligation; it does not establish that Lumsdaine decided to sell stock to outside investors.

Multiplying the reported share count by the stated price produces $35,720.06, consistent with the rounded total. That figure measures the value of the shares involved at the reported transaction price. It does not describe cash proceeds from an exchange trade or the value of Lumsdaine’s remaining investment in Ardent Health.

The supplied record does not give his holdings after the transaction, the proportion of his stake represented by the surrendered shares, or the underlying compensation award. Those omissions limit what can be stated about the size of the change relative to his overall ownership. The record also does not provide the tax rate used or a breakdown of the withholding obligation.

How Form 4 and share withholding work

Form 4 is the SEC disclosure used by corporate insiders to report most changes in beneficial ownership of their company’s securities. The reporting framework generally covers directors, designated officers and shareholders who own more than 10% of a registered class of equity securities. Most reportable transactions must be disclosed within two business days, subject to applicable exceptions.

These filings are public ownership records. They can cover purchases and sales, but also grants, option exercises, gifts and shares withheld or surrendered for taxes. The transaction category is therefore part of the factual record a reader needs when interpreting a change in an insider’s holdings.

Tax withholding can arise when stock-based compensation becomes taxable. Depending on an award’s terms and the company’s arrangements, shares may be retained or surrendered to meet withholding requirements. This mechanism reduces the shares delivered to or retained by the recipient. The supplied information identifies that tax-related mechanism here, but does not specify the award or taxable event behind it.

The record also states that the transaction was not made under a Rule 10b5-1 plan. Such plans can provide an affirmative defense against insider-trading liability when their requirements are met, allowing transactions under arrangements established in advance. A transaction outside such a plan does not, by itself, establish misconduct or explain an executive’s expectations for the share price.

What to watch

The full filing’s ownership table and any explanatory footnotes are the next places to check for remaining holdings and award details. Subsequent disclosures may document additional ownership changes. The supplied record establishes this tax-withholding transaction, but does not establish any later activity or Lumsdaine’s view of Ardent Health’s prospects.
