Lindgren Mark C 4

What Happened

• Mark C. Lindgren, EVP and Chief HR Officer of a subsidiary of Ameren Corporation, had two dispositions tied to equity compensation and a planned sale. On 2026-02-27, 2,054 shares were withheld/used to satisfy tax withholding related to vesting (reported as "Payment of exercise price or tax liability") at $113.28 per share for ~$232,677. On 2026-03-03, he sold 2,073 shares in an open-market transaction at $111.84 per share for ~$231,844. Combined proceeds/consideration across both actions are about $464,521. These are dispositions (sales/withholding), which are commonly routine for tax payment or planned sales rather than indicative of a buy signal.

Context

• The first disposition was a tax-withholding action tied to equity vesting (common when restricted stock units or performance shares vest). The second was an open-market sale executed under a pre-established 10b5-1 plan. Both are routine mechanisms insiders use to cover taxes or monetize compensation and do not, by themselves, convey management’s view of the company.
