2016 Summary Annual Report Message to Shareholders William J. Wagner – Chairman, President and CEO A year of significant transformation for our company. The Board of Directors, management team and entire staff of Northwest Bancshares, Inc. and Northwest Bank are pleased to report on a year of significant transformation for our company. Highlighted by the final integration of the Lorain National Bank (LNB) acquisition in northeastern Ohio, which began in August 2015, and the acquisition of 18 former First Niagara Bank offices in Western New York in September 2016, we realized a record increase in earnings and earnings per share while greatly improving the quality and reach of our branch network. Non-GAAP net operating income for the year ended December 31, 2016, which excludes debt prepayment penalties, restructuring and acquisition expenses and ESOP termination fees, was $84.3 million, or $0.84 per share. This represents an increase in non-GAAP operating income of $17.3 million, or 25.8%, from the previous year. Similarly, non-GAAP earnings per share increased by $0.13, or 18%, from a year ago. Perhaps more importantly, net income for the fourth quarter of 2016 of $24.5 million, or $0.24 per share, represents an increase of $9.2 million, or $0.07 per share, compared to the quarter ended June 30, 2015 – the final quarter of operations not impacted by either the LNB or First Niagara acquisitions. This represents a 60% increase in earnings and a 40% increase in earnings per share over a period of just six calendar quarters – unprecedented income growth for our company. The benefits of these acquisitions reached even deeper as they improved the strength of our balance sheet, elevated interest rate sensitivity and enhanced the value of our franchise. The loan portfolios from both acquisitions were relatively diverse, which improved the mix of our existing portfolio while enhancing the sensitivity of the portfolio to changes in interest rates. The impact to our liabilities was even more significant as both acquisitions brought considerable checking account balances, which greatly lowered our cost of funds and provided additional protection from the potentially negative impact of rising interest rates. With that, we realized a 30-basis-point increase in our net interest margin to 3.75% from 3.45% over the past six quarters. Finally, the value of the Northwest franchise was greatly enhanced as we added 38 deposit-rich offices and used a portion of those deposits to replace approximately $700 million of high-cost borrowings. We believe the franchise value of a bank is primarily driven by the quality of the branch offices, size of their related deposits and the number and depth of the customer relationships that lie within. With these two acquisitions, we added over 150,000 new households to our growing list of loyal Northwest customers. 1 Our entire staff worked tirelessly over the past 18 months to complete the two largest acquisitions in our history while consolidating 24 offices. Another major factor in our earnings improvement in 2016 was the consolidation of 24, or 13%, of our branches. This decision did not come easy, as we demonstrated considerable concern for the employees, customers and communities involved. Accordingly, most of the offices that closed were in close proximity to another Northwest office so customer inconvenience was kept to a minimum. As a result, retention of these customers was significant, with few of them choosing to leave our bank. The combined impact of these consolidations and the aforementioned two acquisitions pushed the average deposit size of our offices to $48.1 million as of December 31, 2016, a 31% increase over the average balance of $36.7 million at June 30, 2015. Since office efficiency relates directly to deposit size, this increase in average deposits should enhance efficiency in the years ahead. It obviously took a tremendous effort on the part of our entire staff to complete the two largest acquisitions in our history while consolidating 24 of our offices in a period of just 18 months. We cannot thank them enough for their enduring energy, endless enthusiasm and unwavering devotion to our company. But their efforts didn’t stop there. Throughout 2016, we continued to enhance the Northwest customer experience by converting all of our customers to a new online banking system, which was a monumental task. We also replaced all our customers’ debit and credit cards to provide them with EMV chip technology; moved our bill pay customers to a new system; added Apple, Android and Samsung Pay and completed most of the legwork for the new Northwest website, which will launch in 2017. With a continued focus on efficiency, we digitized all our commercial loan documents, brochures, customer letters and marketing materials; introduced a commercial loan pricing model; developed enhanced profitability reports by product and business line and implemented a new online loan collection system. We were also pleased to provide our shareholders with a stellar return on their investment in 2016. As a result of our improving performance and a meaningful increase in market sentiment for bank stocks, the price of Northwest’s common shares increased $4.64, or 35%, to $18.03 during the year. Given our strong capital position, we were again able to return capital to our shareholders in the form of robust common stock dividends. Dividends paid during the year of $0.60 per share represented a 4.50% dividend yield based on the beginning-of-the-year market value. The most recent quarterly dividend payment of $0.16 per share represents a 3.5% dividend yield based on the December 31, 2016 market value of $18.03. We also continued our tradition of J.D. Power recognition in 2016 when we were ranked "Highest Customer Satisfaction with Retail Banking in the Mid-Atlantic Region" for the fifth time in seven years. Our employees cherish this award, as it is an independent validation of their devoted efforts to provide exceptional customer service. Looking ahead, we believe our future is the brightest it has been since the economic crisis began in 2008. Our primary performance metrics, return on assets and return on equity for the fourth quarter of 2016, the first full quarter of 2 The price of Northwest's common shares increased $4.64, or 35%, to $18.03 while dividends paid of $0.60 per share represented a 4.50% yield. operations following the First Niagara branch acquisition, were 1.01% and 8.37%, respectively. These levels compare favorably to our peer group for the first time in several years, and we are committed to working diligently toward further improvement in those returns. Asset quality is at its highest level since before the Great Recession, and we have made tremendous progress enhancing our lending and credit processes while improving lending capabilities and customer satisfaction. Our regional business development teams are keenly focused and well positioned for additional production and revenue growth, while our risk management functions have added the manpower and sophistication necessary to meet the regulatory expectations of a $10 billion bank. Finally, our entire staff remains focused on efficiency with a devoted effort to simplify our operation in every way possible. For all of these reasons, we believe we can say without reservation that our institution is substantially stronger and better prepared than at any time in our 120-year history. Crossing the $10 billion threshold for total assets weighs heavily on our plans for the future. With current assets of $9.6 billion, we are on the cusp of that consequential milestone. We estimate that the loss of interchange income relating to the impact of the Durbin Amendment of the Dodd- Frank Act will be approximately $8 million annually, while the cost of the additional regulatory burden will be approximately $3 million per year. The after-tax reduction in income from these two items will be approximately $7.0 million, or $0.07 per share. With that, we are hopeful that Northwest will be able to secure the acquisition of another bank of sufficient size and earnings power so that the additional earnings from the acquisition offset the $7 million lost by crossing the $10 billion threshold. Since the determination date for being subject to the Durbin Amendment is the end of each calendar year, it seems doubtful at this time that we will be able to secure such an acquisition and close the deal by the end of 2017. It is also doubtful that organic growth will take us over the threshold by that date. Accordingly, it appears that we will not feel the impact of Durbin until 2019 at the earliest. In addition, we are hopeful that the new Administration and Congress in Washington will seek meaningful regulatory relief for our industry, which includes the elimination of the Durbin Amendment and the revision of certain sections of the Dodd-Frank Act, including those related to the capital stress testing requirements of a $10 billion bank. We continue to support the industry's efforts in lobbying for such change. In summary, we hope this letter adequately conveys the tremendous pride that the Board of Directors, management and entire staff share in Northwest’s accomplishments over the last two years. On behalf of those stakeholders, I thank you for your continued support and investment in our company. Sincerely, William J.
