Thank you, Delim. Good afternoon, everyone. Thank you for joining us as we review Columbia's first quarter results and the announced acquisition of Pacific Premier Bancorp. The news releases and corresponding presentations are available on our website columbiabankingsystem.com. During today's call, we will make forward-looking statements, which are subject to risks and uncertainties and are intended to be covered by the safe harbor provisions of federal securities law. For a list of factors that may cause actual results to differ materially from expectations, please refer to the disclosures contained within our SEC filings. We will also reference non-GAAP financial measures, and I encourage you to review the non-GAAP reconciliations provided in our earnings materials. I want to thank each of you again for joining on short notice. I'm eager to get to our discussion of Pacific Premier, an acquisition which I'm excited to talk about, but we also have another solid quarter of results to share with you. Our consistent, repeatable performance in 2024 carried through to the first quarter of 2025. Our results reflect our disciplined focus on relationship banking as our teams work toward long-term balanced growth in deposits, loans, and core fee income. Our net interest margin contracted modestly as anticipated in the first quarter given customer cash usage in December that carried through into January. But the positive effects of our retail and small business deposit campaigns as well as growing commercial balances offset these impacts. Defined seasonal norms with $440 million in net customer deposit growth for the quarter. Loan origination volume was up 17% from the first quarter of 2024, as momentum from the fourth quarter carried through into the new year. Our banking teams continue to win new business with new and existing customers. However, total loan balances were relatively flat as of quarter end due to higher prepayment and payoff activity. Period end totals were also muted by our continued focus on pushing the transactional real estate loans discussed in previous quarters off our balance sheet. Beyond the nonrecurring items that impacted our expenses in the first quarter, Columbia maintained its disciplined cost culture while continuing to reinvest in our growing franchise. We opened our first retail branch in Colorado in March, in support of the banking teams that have already been offering our full suite of products and services in the market since 2022. We'll continue to fine-tune our branch footprint and expand in geographies where we see opportunities. On that point, today, we announced our partnership with Pacific Premier. With this acquisition, Columbia will become a $70 billion in assets franchise and pick up a complementary set of products and services to support our growing customer base. Our eight-state Western footprint remains intact but as Pacific Premier's footprint is heavily weighted in Southern California, we accelerate our strategic goals in this market by a decade or more. I'm not going to take you through a page-turn presentation of the deal deck, but I will reference certain key slides during my remarks. Slide four in the deck highlights the highly complementary footprints of Columbia and Pacific Premier. I've previously discussed Columbia's expansion plans in Arizona, Colorado, Utah, and Southern California. A de novo branching strategy accomplishes our coverage goals in the first three states but Southern California is different. There are 13 million people in the Los Angeles market alone, which is more than Washington and Oregon combined. And there are over 20 million people in the broader Southern California market. Pacific Premier's Southern California footprint fills in our western reach, from Canada to Mexico, and it enhances our presence in other growth markets like Las Vegas and Phoenix. This acquisition provides the physical footprint to support our Southern California banking teams who have done a phenomenal job with limited infrastructure. It also provides expanded capabilities to the PPBI team through broader product offerings and the benefits of a much larger balance sheet. Columbia's deposit market share position in Southern California moves from fifty-first to number 10 on a pro forma basis. As outlined on slide eight, Ron will cover the numbers behind this financially attractive acquisition in greater detail. But as part of the all-stock transaction, Pacific Premier shareholders will receive a fixed exchange ratio of 0.915 of a share of Columbia stock for each Pacific Premier share. Following the deal's closing, Pacific Premier shareholders will own 30% of the combined company and Columbia shareholders will own 70%. Notably, we expect the transaction to have minimal impact on Columbia's capital ratios and we do not need to raise additional capital to support the deal. Columbia's executive leadership team remains intact and three Pacific Premier directors will join Columbia's board including Steve Gardner, Pacific Premier's chairman and CEO. The combined organization will operate under the unified brand of Columbia Bank, as Umpqua Bank will change its name to Columbia Bank later this year. Columbia Bank name aligns with our holding company name and other brands the bank operates today, simplifying our family of brands and ensuring brand clarity as we deepen our presence throughout the West. Beyond double-digit EPS accretion, and a short earn-back period, this transaction represents a strategically compelling partnership as slide five outlines. Columbia and Pacific Premier are like-minded business banks that share a relationship-based operating philosophy. The banks have nearly identical low-cost deposit compositions including a top quartile percentage of noninterest-bearing deposits. Pacific Premier's products and service offerings are additive to Columbia's as we strive toward a larger contribution of fee income to our revenue stream. Pacific Premier's custodial trust business complements our existing wealth management platform, adding new capabilities and revenue-enhancing opportunities. We'll also add Pacific Premier's attractive HOA banking, escrow, and 1031 exchange businesses driving additional fee income and adding low-cost core deposits as detailed on slide 10. Execution risk for this transaction is low. It is predominantly an expansion in existing markets with limited overlap, and we expect very little disruption to depositors, borrowers, and our banking teams. Companies have similar credit cultures, founded on conservative underwriting, robust review processes, and relationship-centric banking. Our thorough due diligence process confirms significant alignment in our credit approach, go-to-market strategy, operating philosophies, and cultures. In addition, both companies have significant acquisition experience and integration talent so we expect a smooth combination in every respect. I want to take a moment to address heightened macro uncertainty and the recent market volatility. Columbia's consistent approach to banking is a key contributor to our success through business and credit cycles. Our conservative and disciplined approach to building a diverse and granular balance sheet anchored by enduring customer relationships has historically allowed us to thrive during volatile periods. Our company has grown stronger as we have gained scale, talent, and process improvement through the mergers and acquisitions that have shaped Columbia over the years. Through it all, we have maintained our culture, supported our growing customer base, maintained our strong credit profile, and built a superior core deposit franchise. I want to thank our associates for their hard work in delivering another solid quarter of operational results. Their accomplishments contribute to my enthusiasm for our future. Our pending acquisition of Pacific Premier accelerates the organic opportunities in front of us as we continue to grow our customer base throughout our eight-state Western footprint. Together, we continue to strive toward consistent, repeatable top quartile performance in support of long-term shareholder value.
