Okay. Thank you, Clint. And for those on the call who want to follow along, I'll be referring to certain page numbers from our earnings presentation. Starting on Slide 4. Now that we've closed the merger, we present here updated overall financial metrics expected as compared to the original projections in October of 2021. The changes in fair value since then led to significant rate related discounts, which will accrete through interest income over time. With that, our tangible book dilution was larger, but our expected GAAP accretion and return on tangible equity increases significantly, with a similar earn back. With our core system conversion completed a month ago, we are on track to achieve our expected cost synergies of $135 million on an annualized basis by the end of the third quarter this year. Next on Slide 5, we present updated fair value marks at closing as compared to announcement. Given the increase in treasury yields and inversion of 10 versus 2 spreads since announcement, we ended with $1.76 billion in discount marks with all but $130 million of that related to rate. Again, these rate discounts will accrete to interest income, providing a significant and stable additional earnings stream over time, which I'll highlight in a few minutes. Also noted lower in the page is the larger core deposit intangible balance, which will be amortized to expense over time. On Slide 6, we carry forward the discount marks in CDI at closing and also present the current balances as of quarter-end. For the AFS securities discount, the decline from closing to quarter-end resulted from writing-off existing premiums at close of roughly $200 million, along with removing the discounts of $165 million on the $1.2 billion of bonds sold as part of a restructuring. The remaining decline of approximately $15 million was accreted to interest income. Slide 7 projects our cost synergy realization estimate at quarter-end through the year. On an annualized basis, we estimate we realized $25 million of cost synergies in the month of March run rate with an additional $21 million achieved post conversion, which will reduce our run rate in April. Looking forward, we expect to realize a further $59 million to $64 million in annualized cost savings by the end of the second quarter, or approximately $15 million to $16 million on a quarterly basis, achieving these synergies evenly throughout the quarter. Slide 8 covers our liquidity, including deposit flows during the quarter. For comparability, we presented the table on the left as if we were combined for all periods presented. Total deposits declined 4.9% in the first quarter, or 3.6% when excluding the divestiture required with the combination. Market liquidity tightening and the impact of inflation on consumer spending continued to pressure customer deposit balances. We utilized short-term Federal Home Loan Bank borrowings to fund the outflows, along with adding $2 billion for higher on-balance sheet liquidity. The upper-right table, details our off-balance sheet liquidity with $9.7 billion available as of quarter-end. Below that, we had cash and excess bond collateral not pledged for lines to arrive at total available liquidity of $17.9 billion. This represents 121% of uninsured deposits as of quarter-end. On the next page, Slide 9, we detail out the investment portfolio. The upper-left table takes you from current par to amortized cost to fair value, noting the difference between current par and amortized costs is the combined net discount, which will be accretive to interest income over time. The $94 million of gross unrealized gains at quarter-end came primarily from the marked Columbia portfolio as the bond market rallied in March, while the gross unrealized losses related to the prior Umpqua bonds, which were not marked. I mentioned earlier, we sold $1.2 billion of marked Columbia bonds the first week of March and reinvested $0.9 billion as part of a restructuring. We sold front-end cash flows and purchased longer-dated bonds to extend duration slightly, benefiting our interest rate sensitivity, which I'll cover in a few minutes. The chart on the right breaks out the overall portfolio between the portion with unrealized gains versus losses, noting $6.1 billion of the book is in a gain position with a book yield of 4.53% as of quarter-end. As you can tell, I'm excited about this portfolio as it gives us a significantly higher and stable earnings stream with greater optionality. The overall book yield was 3.62% with an effective duration of 5.7% at quarter-end. And lastly, we only have $2.4 million in HTM bonds, which represents some CRE-related bonds with no unrealized loss. Now to better help investors given the combination accounting and moving parts, on Slide 10, we provided an updated outlook for the remainder of the year on several key financial statement items. The accretion estimates, noted on the lower half of the table, accrete based on the effective interest method, meaning they should be fairly stable near term and declining slightly over the life of the portfolios. They will provide significant interest income and capital build over time. We also provided an updated outlook for our quarterly expense run rate, which we expect to be in the $260 million to $270 million range in Q2, when CDI amortization and merger expenses are excluded. We expect this level to trend down to $240 million to $250 million in Q4, reflecting the expected achievement of all communicated expense synergies by the end of the third quarter. Slides 12 through 14 provides summary financials for Q1, but I want to take you forward to Slide 15. Here, we break out Q1 GAAP earnings to help investors understand the non-operating and merger related impacts and resulting core bank results in the far right column. The first column represents our Q1 GAAP results, with a net loss of $14 million, driven entirely by merger expense, along with the initial ACL provision. The second column includes our non-operating designation for income statement changes mostly related to fair value swings, along with $116 million of merger costs included in non-interest expense, which are detailed out in the appendix. These led to an $86 million reduction in Q1 earnings, resulting in the third column for operating income. This is the key page the bridge from GAAP reported earnings isolating non-operating fair value changes, then the merger related items of discount accretion, CDI amortization and the CECL day 2 double count then to adjusted operating income. Now in the merger related items column, we have $32 million of net discount accretion from the marks discussed earlier for one month, along with $88 million initial ACL provision, commonly referred to as the CECL day 2 double count. Also included is $13 million of CDI amortization for the one month. The value in this column will be a clear view of the net earnings impact from the merger accounting, which will be substantial and again build capital over time. And that takes us to the far right column, which presents the bank excluding the merger accounting marks. Again, the interest rate environment introduced a significant amount of purchase accounting accretion and amortization into our reported earnings, and Slide 15 breaks out the components. This will enable investors to view the earnings power of Columbia outside purchase accounting adjustments, while also seeing the meaningful net capital generation we expect these adjustments to produce over time. Okay, with that moving ahead for a couple more items. Slide 17 breaks out accretion from net interest income, and Slide 18 does the same for the margins. In the footnote, we highlight the NIM for just the month of March was 4.31% as reported and 3.55% excluding the accretion. The excess liquidity held on balance sheet had a 10 basis point impact on the month of March NIM, but an insignificant impact on net interest income. Slide 19 breaks out the repricing and maturity characteristics of the loan portfolio, noting 46% is fixed, 24% is floating and 30% are adjustable. Slide 20 provides an updated view of our combined interest rate sensitivity, under both ramp and shock scenarios. We've taken proactive measures to reduce the balance sheet sensitivity to a potential declining rate environment, including the bond portfolio restructuring discussed earlier, along with using short-term wholesale borrowings. Combined with more locked out bond cash flows, this acts like a swap for rates down environments. You can see here the trend over the past few quarters where our rates down risk has been reduced significantly. And noted below, we calculate our cycle-to-date funding betas, which are calculated on a combined company basis over the periods presented for comparability. As of the first quarter, our interest-bearing deposit portfolio has priced in 28% of the Fed funds rate increases. Notably, here is cost of interest-bearing deposits, which was 1.33% for the month of March compared to the quarter-end spot rate of 1.43%, highlighting stability. And with that, I will now turn the call over to Frank.
