The assessment is 'likely_true' because one of the two claims in the statement is strongly supported by high-quality evidence, while the other is unmentioned. A highly authoritative source (MarketBeat), which directly reports on SEC filing data, explicitly confirms that Pershing Square 'lifted' (increased) its holdings in Brookfield (BN). This provides strong verification for the first part of the statement. However, none of the provided sources contain any information regarding Pershing Square's investment in Google, meaning there is no evidence to support or contradict the claim that its stake was decreased. Because a significant part of the statement is factually confirmed by a credible source and there is no conflicting evidence, the statement is rated as 'likely_true'. The confidence level is 'medium' because the second part of the statement remains entirely unverified by the supplied materials.
