EVP/CAO Arnst Thomas W sold 8,000 shares (99.9% of holdings) at $238.85 avg for $1.9M on 2026-03-09.

Arnst Thomas W, EVP, Chief Administrative Officer and General Counsel, executed 2 separate sales totaling 8,000 shares for $1,910,777.44, leaving only 12 shares post-transaction. The blended average transaction price of $238.85 is near the current price of $237.42 and within recent trading range context (52-week high $244.80). Across his prior 4 measurable sales at THC, 0 of 4 were well-timed at the 90-day mark, meaning the stock rose after each prior sale; his 90-day average return post-sale at THC was +20.4%, suggesting a pattern of selling ahead of appreciating periods. The near-complete portfolio exit by a C-suite legal and administrative officer differs materially from his smaller prior sales at this ticker and warrants investor attention to accompanying circumstances (severance, resignation, planned departure, or personal portfolio realignment).

Significance 6/10

EVP Thomas Arnst sold 24,000 THC shares at $234.04 on 2026-03-02; stock now at $242.88 (+0.0% from 52-week high)

Arnst, the Chief Admin Officer and General Counsel, divested 75.0% of his holdings (24,000 shares, $5.6M) at $234.04, retaining 8,012 shares post-transaction. The sale occurred near the 52-week high of $242.88, with the stock up 28.3% over the prior 30 days and 14.9% over 90 days. His prior trades at THC have been poorly timed overall: of 5 prior sales at this ticker, only 1 was well-timed (negative 90-day return), while the other 4 were followed by positive returns ranging from +7.2% to +41.6%, indicating he typically sold before upside materialized. His cross-ticker track record shows a 33.33% well-timed rate across 6 prior sells, which is below a 50% baseline and suggests inconsistent timing discipline. The fundamental backdrop—$5.3B quarterly revenue, +3.1% annual growth, and a P/E of 35.30—reflects a mature healthcare operator trading at a premium valuation; the executive's near-complete exit warrants observation given the recent momentum and his historically reactive sell pattern.

Significance 6/10

EVP Thomas W Arnst sells entire 9,786 share THC stake at $166.00; zero-balance exit clears position at near 52-week highs

Thomas W Arnst, EVP, Chief Admin. Officer & GC, liquidated his complete THC shareholding of 9,786 shares at $166.00 on 2025-05-21, reducing holdings to 0 shares and eliminating all equity exposure. The sale occurred at a price only 3.4% below the 52-week high of $168.66 and coincides with THC's 30-day surge of +34.6%, suggesting the execution captured momentum near recent extremes. Arnst's prior five THC sales (all in 2023–2024) showed mixed 90-day outcomes: three March 2024 sales yielded gains of 39.5%–41.6% over 90 days, while two May 2023 sales produced losses of 2.4% and 3.5%, indicating no consistent pattern of well-timed exits at this ticker. The complete liquidation is a structural inflection—a material officer vacating equity exposure entirely—that merits observation for any accompanying context about leadership continuity or strategic transitions.
