LETTER TO QUANTA SERVICES INC.October 3, 2017 Mr. Earl C. "Duke" Austin Jr. President, CEO and COO Quanta Services Inc. 2800 Post Oak Blvd., Suite 2600 Houston, Texas 77056 Mr. Austin: I am not sure if Quanta Services Inc. is standing in the shadow of public-listed NAPEC Inc. (NPC-Toronto Stock Exchange), which shares are experiencing very unusual high trading volumes since the past two weeks, likely awaiting a "takeover", but nevertheless, I can't let aside the opportunity of letting you that something is definitely brewing up for this company. Back in 2013, company shareholders were not disclosed by the Board of Directors of two attempted takeover offers from Quanta Services Inc., which were rejected. NAPEC has since become a transformed company, but still not able to deliver a rewarding share price value to its shareholders. It has reached today a 52-weeks HIGH of $1.33 (CAN), giving it a market capitalization of approximately $135M. A Bit of History North American Power and Energy Corporation (NAPEC) is a leading service provider to the public utility and heavy industrial markets of Quebec, Ontario and the U.S. Northeast. The specialty contractor primarily builds and maintains electrical transmission and distribution grids across its operating regions. In the U.S., NAPEC also delivers comprehensive services to natural gas utilities, installs heavy equipment for power and petrochemical plants, and offers environmental construction and road matting services. Importantly, it does not offer engineering services, manufacture products or supply materials, consistent with the other contractors included in our Infrastructure & Construction (I&C) universe. As of Dec-31-15 the company employed 9 people at its Drummondville, QC headquarters and another 1,160 between its Canadian and U.S. subsidiariesThirau and Riggs Distler. Approximately 84% of the workforce is unionized, yielding NAPEC the ability to staff large projects in a timely fashion. NAPECs history as a public entity traces back to 2005 and CVTech Groupa public company formed to hold investments in companies with specific, recognized and exportable expertise. The CVTech name took after a business that specialized in the design and manufacturing of continuously variable power transmission (CVT) systems for compact cars and recreational vehicles. Later that year CVTech dove into construction with the $17 million acquisition of Thiro, which served the Quebec and New England electrical transmission and distribution markets. In 2009, the company capitalized on the global financial crisis to purchase Riggs Distler & Company, a 107-year old New Jersey based contractor, for US$37 million. The deal not only extended CVTechs footprint into the Mid-Atlantic region, but also added heavy industrial expertise, including mechanical and electrical fabrication, to its service offering. Expansion into Ontario followed in 2012, when Riggs Distler established a subsidiary and subsequently acquired B.G. High Voltage as a means to bolster its substation capabilities in the province. Despite increasing overlap in coverage, each business unit was left to operate independently, with limited involvement from CVTech senior management. Unfortunately for shareholders this lack of oversight, combined with distractions around the CVT business sale and a lengthy proxy battle over attractive takeout offers quietly rejected by the board, led to two material contract losses in 2013 and 2014. It also paved the way for major changes at both the board and executive levels. None were as pivotal as the appointment of Pierre Gauthier, who led the North American power operations of Alstom before its acquisition by GE, to President and Chief Executive Officer in mid-2014. That summer, the company adopted the NAPEC brand just as Mr. Gauthier set out on a journey to make it more efficient and competitive. The firm adopted the NAPEC name in 2014 to better reflect its true identity: a North American Power and Energy Corporation - NAPEC's website is WWW.NAPEC.CA Good luck, should you get on board.
