July 2018 Chartwell is pleased to announce the successful simultaneous sale of (i) Sierra Aluminum Company (“Sierra” or the “Company”) to Samuel, Son & Co. (“Samuel”), a proven leader in processing and distribution of metals in North America, and (ii) the Company’s real estate in a sale leaseback transaction with LBA Realty, LLC (“LBA”), a real estate investment and management company with a focus on the Western United States. Sierra, a widely regarded, best-in-class provider of standard and custom aluminum extrusions, with significant end-to-end manufacturing and value-added capabilities, had been 100% owned by its Employee Stock Ownership Plan (“ESOP”) since 2006. Since that time, Ed Harris (Chief Executive Officer) and his senior management team successfully grew the business through the economic downturn and enabled the ESOP and its participants to enjoy significant equity appreciation to fund employees’ retirements. Chartwell acted as the exclusive financial advisor to Sierra, providing comprehensive and unbiased advice to the Company throughout the duration of both the corporate and real estate transaction. Following a thorough and complicated sale process, the sale to Samuel was completed on July 9, 2018, providing a significant gain to the retirement assets of the ESOP participants. Simultaneous with the sale to Samuel, a sale leaseback transaction was executed to maximize the equity value of Sierra for the benefit of the ESOP participants. From the commencement of the transaction process, the Board of Directors and management team were highly focused on fulfilling their obligations to the ESOP while preserving Sierra’s superior reputation and employee culture, and positioning the Company for further growth and success well into the future. Chartwell and Sierra’s Board thoroughly evaluated indications of interest from numerous potential acquirers to determine and proceed with the optimal buyer for the Company. Samuel brings significant business acumen and exceptional experience in the metals industry, as well as the capital necessary to propel continued market share expansion and growth. CHARTWELL VALUE ADD “This process began four years ago when the Board of Directors engaged Chartwell to help evaluate the full slate of strategic alternatives for Sierra given our need for growth capital and the ongoing management transition. Chartwell provided high-quality financial analyses and advice regarding a wide array of strategic alternatives, which ultimately led to the selection of an M&A sale as it was the best option to maximize shareholder value. Furthermore, Chartwell identified the value of company-owned real estate and its material, positive effect on ESOP-participant account balances through the sale leaseback transaction. Chartwell worked diligently to help find the optimal buyer for Sierra, providing honest, straight forward feedback along the way with their unrivaled ESOP expertise. Their commitment and dedication in assisting the company in this process is truly appreciated – I’m not sure how we could have done it without them.”Ed Harris, Chief Executive Officer & Chairman of The Board, Sierra Aluminum Company “The extensive transaction process undertaken by Sierra and Chartwell was very well orchestrated and managed by Chartwell. The simultaneous corporate and sale leaseback transaction was quite complicated and involved a vast amount of diligence and financial analysis, as well as coordination among many parties. Chartwell successfully managed the process from start to finish, providing meaningful advice and creative solutions to address the inevitable road bumps along the way. I am very thankful for all of their hard work and assistance in helping realize the retirement balances for ESOP participants, and I am excited to begin our new journey with Samuel to continue serving our customers and employees alike for many years to come.”Robert Horsley, Chief Financial Officer, Sierra Aluminum Company ABOUT SIERRA ALUMINUM COMPANY Founded in 1986 by Bill Hunter and Ed Hudon, Sierra Aluminum is a full-service manufacturer of standard and custom aluminum extrusions.
