& Merger Investor Presentation Acquisition of Penns Woods Bancorp, Inc. December 17, 2024 NASDAQ: NWBI | NASDAQ: PWOD

Forward-looking Statements and Additional Information This presentation contains forward-looking statements within the meaning of the federal securities laws relating to the proposed merger with Penns Woods Bancorp, Inc. (“PWOD”) by Northwest Bancshares, Inc. (“Northwest” or “NWBI”), the integration of PWOD with NWBI, the combination of their businesses and projected or pro forma financial information and metrics. All statements other than statements of historical fact are statements that could be deemed forward-looking statements, including all statements regarding the intent, belief or current expectations of NWBI and PWOD and members of their respective board of directors and senior management teams. Investors and security holders are cautioned that such statements are predictions, and are not guarantees of future performance. Actual events or results may differ materially. Completion of the proposed merger, expected financial results or other plans are subject to a number of known and unknown risks, uncertainties and assumptions that are difficult to assess and are subject to change based on factors which are, in many instances, beyond NWBI's control. Additional risks and uncertainties may include, but are not limited to, the risk that expected cost savings, revenue synergies and other financial benefits from the proposed merger may not be realized or take longer than expected to realize, the failure to obtain required regulatory or shareholder approvals, the failure of the closing conditions in the merger agreement to be satisfied or any unexpected delay in closing the transaction. For further information regarding these risks and uncertainties and additional factors that could cause results to differ materially from those contained in the forward-looking statements, see “Risk Factors” and the forward-looking statement disclosure contained in the Annual Report on Form 10-K for the most recently ended fiscal year of NWBI and PWOD, as well as the proxy statement/prospectus described below, and other documents subsequently filed by NWBI and PWOD with the Securities and Exchange Commission. Due to these and other possible uncertainties and risks, NWBI and PWOD can give no assurance that the results contemplated in the forward-looking statements will be realized, and readers are cautioned not to place undue reliance on the forward-looking statements contained in this presentation. Forward-looking statements are based on information currently available to NWBI and PWOD, and the parties assume no obligation and disclaim any intent to update any such forward-looking statements. All forward-looking statements, express or implied, included in the presentation are qualified in their entirety by this cautionary statement. NON-GAAP FINANCIAL MEASURES In addition to results presented in accordance with GAAP, this presentation includes certain non-GAAP financial measures. NWBI and PWOD believe these non-GAAP financial measures provide additional information that is useful to investors in helping to understand underlying financial performance and condition and trends of NWBI. Non-GAAP financial measures have inherent limitations. Readers should be aware of these limitations and should be cautious with respect to the use of such measures. To compensate for these limitations, non-GAAP measures are used as comparative tools, together with GAAP measures, to assist in the evaluation of operating performance or financial condition. These measures are also calculated using the appropriate GAAP or regulatory components in their entirety and are computed in a manner intended to facilitate consistent period-to-period comparisons. NWBI’s method of calculating these non-GAAP measures may differ from methods used by other companies. These non-GAAP measures should not be considered in isolation or as a substitute or an alternative for those financial measures prepared in accordance with GAAP or in-effect regulatory requirements. Numbers in this presentation may not sum due to rounding. Where non-GAAP financial measures are used, the most directly comparable GAAP or regulatory financial measure, as well as the reconciliation to the most directly comparable GAAP or regulatory financial measure, can be found in this presentation. 2

Filed by Northwest Bancshares, Inc. Pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 under the Securities Exchange Act of 1934 Subject Company: Penns Woods Bancorp, Inc. Commission File No. 0-17077 NEWS RELEASE December 17, 2024 Northwest Bancshares, Inc. Penns Woods Bancorp, Inc. 3 Easton Oval, Suite 500 300 Market Street Columbus, OH 43219 Williamsport, PA 17701 Northwest Bancshares, Inc. Announces Agreement to Acquire Penns Woods Bancorp, Inc. Columbus, Ohio, December 17, 2024 – Northwest Bancshares, Inc. (“Northwest”) (NASDAQ: NWBI) the bank holding company for Northwest Bank, and Penns Woods Bancorp, Inc. (“Penns Woods”) (NASDAQ: PWOD), the multi-bank holding company of Jersey Shore State Bank and Luzerne Bank, jointly announced today that they have entered into a definitive Agreement and Plan of Merger (“Agreement”) whereby Northwest will acquire Penns Woods in an all-stock transaction valued at approximately $270.4 million. Combining the two organizations will significantly enhance the combined company’s presence in North Central and Northeastern Pennsylvania. Headquartered in Williamsport, Pennsylvania, Penns Woods has approximately $2.3 billion in assets, $1.7 billion in total deposits, and $1.9 billion in total loans as of September 30, 2024. The combined company is expected to have pro forma total assets in excess of $17 billion and is expected to be one of the nation’s top 100 largest banks. The combined company’s Pennsylvania banking presence will be enhanced through the addition of 24 branch locations across Blair, Centre, Clinton, Luzerne, Lycoming, Montour, and Union counties. The complementary footprint of Penns Woods links Northwest's presence in both eastern and western Pennsylvania. When the transaction is completed, Northwest will have more than 150 financial centers, as well as loan production offices, across four states. Under the terms of the Agreement, which has been unanimously approved by the board of directors of both companies, Northwest will exchange shares of its common stock for all of the outstanding shares of Penns Woods common stock, in an all-stock transaction. Penns Woods shareholders will be entitled to receive 2.385 shares of Northwest common stock for each share of Penns Woods common stock they own upon the effective time of the merger. Any unexercised stock options of Penns Woods will be canceled in exchange for a cash payment at the spread value over the exercise price. Based on Northwest’s closing stock price of $14.44 as of December 16, 2024, the transaction consideration is valued at $34.44 for each share of Penns Woods which equates to a 139.0% multiple of tangible book value, a 12.8x multiple on LTM core earnings and a core deposit premium of 5.2% as of September 30, 2024. Including the consideration paid to option holders, the aggregate consideration is approximately $270.4 million. The merger is expected to qualify as a tax-free reorganization. Following completion of the transaction, Penns Woods shareholders would be expected to receive, on a per share equivalent basis, a dividend equal to approximately $0.48 per share

based on Northwest’s current quarterly dividend of $0.20 per share. This dividend is approximately 49% higher than Penns Woods’ current quarterly dividend of $0.32 per share. Louis J. Torchio, President and CEO of Northwest, stated, “We are very excited to announce this partnership with the Penns Woods team as this transaction marks another milestone in our long-term growth strategy and executes on our strategic plan. Jersey Shore State Bank and Luzerne Bank have outstanding reputations throughout their respective markets, and we look forward to welcoming our new colleagues and their customers to the Northwest family. We will be strongly positioned to continue to serve communities that are familiar to Northwest, expand our presence into new markets, and deliver exceptional banking services across our entire footprint. Through this acquisition, we look forward to building on Northwest’s rich history of community-focused banking and delivering even greater value to our customers, employees, communities, and shareholders.” Richard A. Grafmyre, CEO of Penns Woods, added, “As Lou mentioned, we are very excited to announce this partnership and are looking forward to bringing together two like-minded institutions. This combination will provide the best path for the long-term success of our organization, employees, customers, and shareholders. We believe that the combination of our highly compatible organizations will create a catalyst for growth and benefit all of the communities we serve. The merger will provide increased scale and additional capabilities for our customers, and it will provide greater opportunities for our employees to advance their careers as a part of a larger organization.” Upon completion of the merger, the shares issued to Penns Woods shareholders are expected to comprise approximately 12% of the outstanding shares of the combined company. The Agreement also provides that Northwest will appoint Richard A. Grafmyre to the boards of Northwest and Northwest Bank after closing. Excluding one-time transaction costs, Northwest expects the transaction to be approximately 23% accretive to 2026 fully diluted earnings per share. Tangible book value dilution is expected to be approximately 9% at closing, with an expected tangible book value earn-back period of under 3 years using the “cross-over” method. The “pay-to-trade” multiple is 0.91x. Northwest and Northwest Bank capital ratios are expected to be significantly above “well-capitalized” regulatory thresholds upon closing. The companies expect to complete the transaction in the third quarter of 2025, subject to the satisfaction of customary closing conditions, including regulatory approvals and approval by Penns Woods shareholders. At closing, Jersey Shore State Bank and Luzerne Bank branches will become branches of Northwest Bank.
