June 20 (Reuters) - NV5 Global Inc (NVEE.O), a U.S. engineering consultant whose business has taken a hit from its exposure to commercial real estate, is exploring a sale, according to people familiar with the matter. NV5 could decide not to go through with a transaction, the sources added, requesting anonymity because the matter is confidential. This exposure to commercial real estate has weighed on NV5's business and stock price. The company's municipal services business has been negatively affected too, he added. NV5 shares have lost about a fifth of their value since the start of the year, underperforming a 31% rise in the NASDAQ Composite Index.
