An update on Pershing Square USA, Ltd. $PSUS: Β  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. Β  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. Β  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. Β  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. Β  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.

.@BernieSanders , it is a time to celebrate. @elonmusk has created enormous value for society by building @SpaceX, driving down the cost of rocket launches and creating a global satellite communication network that has brought high speed, low-cost internet and communication access to hundreds of millions and eventually billions of people along with critical advantages for our military and our nation’s defense. SpaceX and its technologies will cause an acceleration in the growth of wages and wealth creation globally, including in some of the poorest communities in the U.S. and around the world. Access to low-cost, high speed communications everywhere will allow children around the world to be educated, families to build businesses, and life-saving medical knowledge and care to be available everywhere. SpaceX will materially bring down the cost of compute, advancing AI and humanity. Meanwhile, 4,000 SpaceX employees yesterday became millionaires, including hourly wage employees who you claim you are trying to help. The Elon Musks of the world drive growth, global GDP, and provide access to goods and services at lower cost that would otherwise not exist. Elon’s nominal trillionaire status is due to his ownership of SpaceX, Tesla, Neuralink, the Boring Company and his other initiatives that have brought new technologies that improve our everyday lives. Elon is not sitting on a trillion dollar pile of cash, jewelry and gold. He is using his controlling stakes in his companies to advance mankind. Elon’s companies don’t pay dividends. They reinvest all of their capital to accelerate innovation and value creation. Elon is working 24/7 for all of us. He deserves respect and appreciation, not smears. Bernie, your socialism would never allow a SpaceX to be built. Socialism has only proven to impoverish mankind and lead to death and destruction. We need to create the conditions for more SpaceXs to be built, not attack the great entrepreneurs who are helping to advance our country.

To be clear, our sale of $GOOG was not a bet against the company. We are very bullish long term on Alphabet. But at current valuations and in light of our finite capital base, we used $GOOG as a source of funds for $MSFT. https://t.co/0ePZI8p3Bh

I did not blame retail investors for PSUS’ and PS’ price drop. I did explain to the media that we had chosen to favor retail allocations over institutional orders by giving retail investors 100% allocations and cutting back institutions. In most deals, retail investors receive a smaller percentage of their orders than favored institutions. Because the stocks opened late in the day at 1:55pm, investors who received more shares than they wanted were forced to sell in the last two hours of the trading day in order to have the cash to settle their orders the following day. This likely led to dumping of the shares of both PSUS and PS before the market closed. I was not blaming retail investors. I was simply explaining what we believe had occurred. We just did not appreciate this dynamic in making our allocation decisions.

An excerpt from my interview with @CNBC on $PSUS and $PS. I bought 500,000 shares of $PSUS and 800,000 shares of $PS yesterday in the open market. PSUS trades at a large discount to its $49 cash per share and PS trades below the price, $26.25, at which we sold a 10% interest
