The trial court properly admitted HP’s expert’s lost profits opinion.  Unlike the plaintiff in Sargon Enterprises, Inc. v. University of Southern California (2012) 55 Cal.4th 747, HP was an established business.  The expert had based his opinion on HP’s past performance data and considered multiple variables including new product offerings by competing manufacturers.  The expert’s projection of lost profits five years into the future was not unreasonable given the parties’ agreement and business plan which extended for seven years.
