Alphabet Inc., Google's parent company, likes to think big. It has poured billions into what it categorizes in SEC filings as "Other Bets" that encompasses several businesses such as venture firm GV, television gambit Access, self-driving car company Waymo and anti-aging drug developer Calico. But now it's seeking some financial help to support one of its biggest efforts on this front, med tech-focused Verily. Technology private equity investor Silver Lake led a $1 billion financing with participation by the Ontario Teachers' Pension Plan and additional unidentified global investment management firms for an undisclosed stake in Verily.
