That’s the lesson Tibco Software Inc. and Goldman Sachs Group Inc. learned in the software company’s more than $4 billion sale to Vista Equity Partners, which is paying about $100 million less in the deal because of a spreadsheet mix-up. Goldman, Tibco’s adviser in the deal, used a spreadsheet that overstated the company’s share count to crunch the numbers in the deal, according to a regulatory filing. The error led to a miscalculation of Tibco’s equity value, a $100 million savings for Vista and a slightly lower payment to Tibco’s shareholders (roughly 61 cents for each outstanding share).
