SUMMARY ANNUAL REPORT Building for the Future A Message to Shareholders from Ronald J. Seiffert, Chairman, President & CEO In last year’s Message to Shareholders, I shared with you that in 2018 we launched a comprehensive strategic planning process which included the engagement of 26 separate departments within our company. Each of the departments were tasked to develop a new five-year plan for their area of responsibility and to identify key initiatives that, when effectively executed, would contribute materially to achieving the company’s overall corporate objectives. Our corporate objectives include enhancing shareholder value through revenue and production growth, improving efficiency and profitability, mergers and acquisitions, effective risk management and talent acquisition, development and retention. I am very pleased to report to you that in 2019 all key initiatives that were identified through this process were either completed or substantially completed during the year as follows: • We successfully closed and converted our merger with Union Community Bank in Lancaster County, Pennsylvania on March 8, 2019 with minimal customer and employee disruption; • On October 29, 2019, we announced our merger with MutualFirst, a $2.2 billion bank located in Muncie, Indiana, with an expected close date of April 24, 2020; • During the fourth quarter of 2019, we announced the acquisition of Sundahl & Co. Insurance, a property and casualty insurance agency located in Bradford, Pennsylvania, which closed December 2019; • We successfully launched new sales incentive plans for our commercial, consumer, small business and residential mortgage calling officers; • We significantly expanded our residential mortgage capability through the development of a new, state-of-the-art residential mortgage loan origination platform and the development of a broader array of mortgage products (including FHA, VA and USDA). In addition, we introduced new mortgage loan officers (MLOs) into our Cleveland, Ohio and Buffalo, New York metropolitan markets. In order to support the growth generated by these initiatives, we opened a new 8,500 square foot residential mortgage fulfillment center in Columbus, Ohio in April of 2019; • We developed and implemented a new, state- of-the-art commercial loan origination system, making it easier and more efficient to originate commercial loans and track them from origination throughout the life of the loan; • We centralized the monitoring of commercial construction loans and commercial loans secured by accounts receivable and inventory to enhance risk management and to create more efficiencies; • We significantly expanded the distribution of our power sports lending capability to dealerships from Pennsylvania into our other nine-state auto dealer loan markets. In addition, we developed a new, streamlined loan funding process, which reduced the funding times for auto loans from 3-5 days to 24 hours or less; • We engaged an outside firm to assist us in developing analytics tools and a market- driven database to develop more effective and measurable product, price and marketing strategies for our consumer deposit customers. One of the initial deliverables of this initiative was the introduction of our new Affinity checking products suite in November of 2019; • We developed a comprehensive playbook outlining the bank’s treasury management product offerings and business development strategies for our commercial customers. In addition, we introduced new treasury management products and developed real-time 1 tracking of the production of commercial deposits and treasury management fees by our commercial banking officers and treasury management advisors; • We fully deployed financial advisors throughout our footprint from our Northwest Investment Services business; • We developed an initial pathway forward for our digital bank strategy and identified specific investments and deliverables for 2020. The strategy will continue to focus on how we first service and support our existing 450,000 customer households in an easy, simple and fast manner, while providing an exceptional customer experience; • We developed comprehensive and sophisticated systems and processes to fully adhere to the new Current Expected Credit Loss (CECL) requirements; • We continue to enhance the risk oversight capabilities of our model risk management and third-party risk management processes; • We developed a number of employee-related initiatives focused on enhancing our ability to attract, develop and retain employees, including better and more frequent communication, competitive overall compensation, providing for a more flexible work/life balance and providing more effective performance management tools; and, • We developed a comprehensive succession management program which included a senior management mentoring program for high- potential employees; The successful execution of the above initiatives contributed significantly to our 2019 financial performance. For the fiscal year ending December 31, 2019, the company generated record net income of $110.4 million, which represented a 4.7% increase over the previous year despite the significant headwinds caused by declining interest rates and a flat yield curve over the course of the year. As a result of this performance, for the 101st consecutive quarter, our Board of Directors declared a quarterly dividend at year-end, representing a 5.6% increase over the prior year and an annualized dividend yield of 4.57%. Noninterest income experienced exceptional growth for the year, growing by $7.7 million or 8.4% across almost all categories. Our mortgage banking operation is beginning to contribute to earnings in a meaningful way, brokerage investment revenue increased by over 7% and recent changes in our philosophy around fee structures for our deposit products in the fourth quarter will significantly benefit us in 2020. From a balance sheet perspective, loans grew $757.2 million, or 9.4%, with approximately half of this growth contributed by the Union Community Bank acquisition and the other half from internal, organic growth. We were also able to fund half of our loan growth entirely with internal deposit growth. Our credit quality remained sound, our liquidity position remained good and our capital ratios remained strong in 2019, as reflected by our tier 1 capital ratio of 15.00%. 2020 Focus Although we were very pleased with the overall performance of the company in 2019, we recognize there remains plenty of room for improvement. In October of 2019, management of the company presented to our Board of Directors our refreshed strategic plan which included a number of new key initiatives which will drive enhanced financial performance in 2020. These key initiatives for 2020 include the following: • Successfully close and convert MutualBank on April 24, 2020; • Continue to explore merger opportunities within our defined target market with a goal to announce one new bank acquisition during 2020; • Fully implement EVOLVE, Northwest’s customer experience initiative, to move the company away from a product-driven strategy to a relationship strategy focused on the financial wellness of our customers and placing them at the center of everything we do; • Develop a comprehensive retail branch optimization strategy focused on reaching and servicing our customers in a more effective and efficient manner; • Enhance our deposit product solutions for our business customers to include providing advice through self-service tools, resources and readily- accessible human resources; • Expand the deployment of mortgage loan officers (MLOs) to include our Pennsylvania metropolitan markets of Pittsburgh, Lancaster, Erie and our new Indiana region; • Continue to evaluate the geographic expansion of our dealer services auto and power sports business; • Explore new commercial loan products to include potentially new verticals (e.g., healthcare) and new bolt-on acquisitions (e.g., equipment finance) with a focus on expanding our capabilities in our C&I loan business; 2 • Continue to implement our digital bank strategy with a primary focus of serving our existing 450,000 customer relationships in an easier, faster and more efficient manner- while providing an exceptional customer experience; • Continue to establish capabilities to collect, aggregate and interpret data to enhance business processes and decisioning; • Continue to enhance risk management oversight to include commercial lending (as credits become larger and more complex), model risk management and third party risk management; • Fully implement key initiatives identified by our focused efforts on talent acquisition, development and retention to address the war on talent that exists in our industry. These include enhanced communication; work/life balance; total compensation and training, mentoring and professional development to enhance our performance management culture; • Identify and execute initiatives to continue to support diversity and inclusion in our workforce and in our customer base (e.g., women-owned and minority-owned businesses); Through the effective execution of the above initiatives in 2020, we are highly confident that we will build upon our historically-strong financial performance and, in turn, enhance shareholder value. Phillip M. Tredway Retirement On April 22, 2020, following 13 years of distinguished service, Phillip M. Tredway will retire as our lead director and as a board member of both Northwest Bank and Northwest Bancshares, Inc. Phil is President and Chief Executive Officer of Erie Molded Plastics, Inc., located in Erie, Pennsylvania. He also serves on the Pittsburgh Region Advisory Board of the Federal Reserve Bank of Cleveland and is a past chairman and board member of the Manufacturers and Business Association of Erie as well as a past board member and treasurer of Erie Community Foundation. Phil was appointed to the board of Northwest Bank in October of 2006 and to the board of Northwest Bancshares, Inc. in April of 2007. In May of 2014, Phil was appointed lead director of both boards. Under Phil’s strong leadership, in 2015 and 2016 Northwest completed two of its largest mergers (Lorain National Bank in Ohio and the acquisition of 18 offices in greater Buffalo from First Niagara Bank). In 2019, Phil witnessed the merger with Union Community Bank located in Lancaster County, Pennsylvania, and the announcement of the merger with MutualFirst of Muncie, Indiana—the largest acquisition to date in our history. Under Phil’s steady management and leadership approach, the bank has consistently grown its earnings, safely grown its balance sheet, significantly expanded its menu of products and services and increased its level of sophistication and capability as we transitioned from a former thrift institution to a full-service commercial bank. However, Phil’s greatest contribution to the bank has been the character, integrity and wisdom that he exhibited day in and day out as he approached his leadership duties as our lead director. The bank has been extremely fortunate and blessed to have had Phil Tredway serve on our board, and he will truly be missed. Conclusion We are pleased with the financial performance of Northwest Bank in 2019 and over the course of our 123-year history. We are very proud of our consistent historical operating earnings and our balance sheet is strong with sufficient capital to grow organically, continue to make acquisitions and mitigate potential risks associated with future downturns in the economy. We feel strongly that, as a large community bank, we are big enough to provide all the products and services necessary to compete effectively with any financial institution in our marketplace, but small enough to deliver those products and services in a more customer-oriented and community-oriented manner. We believe that we have developed, and are in the process of executing, a very compelling five-year strategic plan that will drive exceptional performance and shareholder value in 2020 and beyond. However, we believe that our greatest strength is our people. We have exceptional employees who are extremely dedicated to the company, to our customers and to the communities we serve. On behalf of our Board of Directors and our 2,200 employees, I wish to thank our shareholders for your confidence in our company and for your continued support! Sincerely, Ronald J. Seiffert Chairman, President and CEO 3 Corporate Profile Northwest Bancshares, Inc.
