Ardent Health, Inc. (ARDT) Securities Class Action Lawsuit Update

A securities fraud class action under the Securities Exchange Act of 1934 has been filed against Ardent Health, Inc. (NYSE: ARDT) covering July 18, 2024 through November 12, 2025 (the Class Period). Investors allege the company misrepresented how it evaluated and reserved for accounts receivable collectability and assured the market its professional liability insurance was sufficient for medical malpractice claims. The complaint says Ardent touted “detailed reviews of historical collections” and management-driven write-offs while, in reality, using a 180-day cliff and a revenue recognition that fully reserved accounts at that mark.

On November 12, 2025, Ardent disclosed a sharp revenue reduction tied to revised collectability under a new system, cut guidance, and increased professional liability reserves ($43 million revenue decrease, $57.5 million cut to EBITDA guidance, $54 million increase to professional liability reserves). The stock fell the next day after a 33% stock price decline, and investors claim significant losses.

Allegations in the Ardent Health, Inc. (ARDT) Securities Class Action Lawsuit

The lawsuit targets Ardent Health, Inc., along with CEO Martin J. Bonick and CFO Alfred Lumsdaine, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. According to the complaint, Defendants told investors that Ardent closely monitored the collectability of its accounts receivable, a key revenue recognition input using “detailed reviews of historical collections” as a primary tool, including hindsight evaluations, and that accounts were written off when management determined they were uncollectible, rather than using a fixed 180-day cliff accounting methodology. They also told the market the company maintained insurance in amounts they believed sufficient for medical malpractice and general liability claims.

The narrative begins with the Registration Statement dated July 17, 2024. On that day, Bonick and Lumsdaine stated Ardent relied on “detailed reviews of historical collections” as a primary source of information as part of its collectability framework and represented that collection procedures continued until management deemed an account uncollectible, at which point it would be written off as part of an active monitoring process. The same filing assured investors that Ardent carried professional malpractice and general liability insurance in sufficient amounts to cover claims.

During this period, management characterized collectability pressures as slower payments rather than nonpayment, as reflected in remarks by Bonick and Lumsdaine, attributing issues to third-party payors and downplaying payor denials. On May 14, 2025, at the Bank of America Global Healthcare Conference, Bonick said, “It’s turning more into a slow pay versus not getting paid,” reinforcing that point, with denials becoming slow pay.

Meanwhile, behind the scenes, investors allege a different reality, including inflated accounts receivable balances. The complaint states Ardent did not primarily rely on detailed hindsight analyses or management determinations; instead, its accounts receivable framework “utilized a 180-day cliff at which time an account became fully reserved”, which investors say overstated revenue. It further alleges Ardent maintained professional malpractice liability insurance for claims arising from its operations and maintained insufficient insurance.

The Truth Emerges

The truth surfaced after market hours on November 12, 2025, and continued on a November 13, 2025 earnings call on the third quarter 2025 results. Ardent revealed a $43 million decrease in third quarter 2025 revenue due to revised determinations of accounts receivable collectability following a revenue accounting system transition. The company also cut its 2025 EBITDA guidance by $57.5 million and recorded a $54 million increase in professional liability reserves (a 9.6% reduction at the midpoint), including New Mexico claims from 2019-2022.

On the call, Lumsdaine explained that the new system “recognizes reserves earlier in an account’s life cycle,” and contrasted it with Ardent’s prior framework, which “had utilized a 180-day cliff at which time an account became fully reserved.” He also acknowledged “an increasing dynamic year-over-year of increasing premiums, increasing costs in the New Mexico market.” These revelations contradicted earlier statements that emphasized detailed historical collection reviews as the primary basis for collectability and assurances about sufficient professional liability insurance.

Market Reaction

The market reacted immediately to the corrective disclosures. On November 13, 2025, following the after-hours disclosures, Ardent’s NYSE: ARDT stock fell $4.75 per share, or nearly 34%, dropping from $14.05 on November 12, 2025 to close at $9.30, on unusually heavy trading volume.
