An update on Pershing Square USA, Ltd. $PSUS:   Since its IPO on April 29th, PSUS has deployed nearly 85% of its capital in 12 companies including Amazon, Microsoft, UBER, Meta, Brookfield, Restaurant Brands, Fannie Mae and Freddie Mac at prices we believe to be extremely attractive.   The PSUS portfolio, along with the other Pershing Square funds, also includes four new companies, which we will disclose at the time of our second quarter report.   As a result of our investment activity over the last six weeks, we believe the PSUS portfolio is now invested in a number of the highest quality durable growth companies in the world, which are trading near their all-time lowest valuations.   Furthermore, as of this moment, PSUS is trading at a ~20% discount to the net asset value (NAV) of its underlying holdings so a buyer of the stock at today’s price is acquiring the current portfolio at a double discount. We believe the PSUS discount to NAV has emerged due to short-term technical factors related to the IPO that should moderate over time.   Pershing Square management and affiliates are all-in, having acquired more than ten million shares or $500+ million of PSUS in the IPO and in the market thereafter. In summary, we believe PSUS and its portfolio holdings represent an extremely attractive bargain at today’s share price and we have put our money where our mouth is.

@blutomus @CernBasher @Tesla @SpaceX @CathieDWood 1. Yes. The SPARs held by PSTH holders would go live as part of this transaction and become exercisable for SpaceX stock on the same terms as the other holders. 2.

This court decision is very positive for @UMG whose share price experienced a ~25% decline on fears that Bollore would have to sell its 18% stake in UMG to fund a buyout of minority Vivendi shareholders. The stock decline began this summer on July 28th with Cyrille Bollore’s surprise resignation from UMG’s board in order to increase Bollore’s flexibility to sell UMG stock. With this court decision, the Bollore ‘overhang’ has now been removed. UMG stock is extremely cheap at its current valuation. As of last night’s close, it was trading at its all-time lowest valuation of 20 times next year’s earnings without assigning any value to the company’s 6.49 million shares of @Spotify.

Vueling is owned by International Airlines Group whose CEO is Luis Gallego Martin. How can a CEO not take responsibility for the actions of his employees? Where is his accountability? Where is the board of directors? Why are they not holding their CEO accountable? What does US ally Qatar, the 26% shareholder of $IAG LN have to say about this?
