$Alphabet - C(GOOG.US): Calculated the price of this $80 billion share issuance:

Berkshire Hathaway: Class A shares $351.81 / Class C shares $348.20

The $15 billion ordinary share placement underwritten by Goldman Sachs and other investment banks: Based on the after-hours price after Tuesday's negative news-driven sell-off, and after deducting the usual discounts for large institutions, the final cost for the first-tier Wall Street firms to acquire common shares is locked in at around $360.

Secondly, the other $15 billion in mandatory convertible preferred shares, due to the inclusion of a 15% to 25% premium rule, the initial conversion cost for institutions in the future will be as high as between $420 and $450 (primarily aiming for the fixed dividend before conversion).

The largest portion, the $40 billion ATM (At-The-Market) direct sale plan, as it will only start in the third quarter and involves a 'drip-feed' style sale directly into the secondary market, has no fixed cost at all, entirely depending on the real-time market price at that time.

In comparison, the main common share cost for Wall Street is about 3.5% higher than Buffett's base price of around $350, while the costs for the convertible shares and the third-quarter ATM plan are even higher or more uncertain.

Berkshire's move might indicate Google could become a potential value stock in the AI era, with its money-printing profitability, ability to sell 'shovels' (infrastructure), develop TPUs, and have its own software ecosystem—a true all-rounder. Starting to build a position at 350+.
