I cannot create a summary of the requested article because the search results provided do not include an article titled "STAT+: HCA expects $1 billion hit from loss of ACA tax credits, Medicaid changes". The search results contain information about HCA Healthcare from other sources, including a 2026 earnings forecast report[2] and analysis on demographic trends[1][3], but not the specific article you requested to summarize. Without access to the original text of the article, I cannot comply with your request to write only verified facts from it. If you have the text of this article available, I can create an accurate and factual summary in Slovak.
