Thank you. This is Thomas Kemly, Columbia Bank. Today, we are excited to announce that Columbia and Northfield have entered into a merger agreement valued at approximately $597 million. Upon completion of the transaction, Northfield Bank will merge into Columbia Bank, with Columbia Bank being the surviving entity. The combination of the two organizations will create the third largest regional bank headquartered in New Jersey with pro forma total assets of approximately $18 billion and over 100 branches, stretching our footprint to 14 counties in New Jersey as well as Brooklyn and Staten Island, where we will have the #1 deposit share for community banks in that market.
In connection with this announcement, we also adopted a plan of conversion to a fully public stockholding company form. This transaction is commonly referred to as a second step conversion. The second step conversion and the merger are expected to be completed early in the third quarter of 2026, subject to the receipt of all regulatory and shareholder approvals and the satisfaction of customary closing conditions. The merger is valued at approximately $597 million or 0.86x Northfield's tangible book value. Based on a preliminary valuation by an independent appraiser with respect to our second step conversion and stock offering, we anticipate approximately 50% of earnings accretion in 2027. The tangible book value dilution of 4.4% and an earn-back on tangible book value is a modest 1.8 years.
The transaction will be in stock or cash consideration, with cash consideration to be paid for up to 30% of outstanding Northfield shares. The merger consideration per Northfield share will be based on the final valuation appraisal of Columbia, as is required by the bank regulators for a second step conversion. On a pro forma basis, at closing, the merger consideration, depending on the final appraised value, will range from $14.25 to $14.65.
Upon completion of the transaction, I will continue to lead the combined organization as President and CEO; and Dennis Gibney, who was recently promoted, will be the first Senior Executive Vice President and Chief Banking Officer. And I'm excited to announce that Steve Klein will be joining our team as Senior Executive Vice President and Chief Operating Officer. The resulting Board will consist of 13 directors, 9 from Columbia and 4 from Northfield, including Steve Klein.
Since going public in 2018, Columbia has successfully leveraged its initial capital to grow the bank to nearly $11 billion, in part through 4 successful mergers and also organic growth. As we approached $10 billion in assets in 2022, the bank built the internal infrastructure and risk management practices to meet regulatory expectations and to support continued growth as a regional community bank. Acquiring Northfield simultaneously with a second step conversion creates a formidable New Jersey/New York metro competitor while leveraging the conversion proceeds to allow the company to achieve a normalized return on equity faster than on a stand-alone basis.
By undertaking the second step conversion, we are eliminating the minority discount embedded in Columbia's stock as a mutual holding company and positioning the bank for future growth in important and vibrant markets. We believe that the merger with Northfield is financially attractive, and we expect it to significantly improve the operating performance, the balance sheet and strategic position of the pro forma company and accelerate the bank's business strategy. Additionally, this combination expands the franchise into new opportunistic markets while adding $1.8 billion in deposits in New Jersey, adding density and expanding our existing New Jersey franchise.
As reflected on Page 8, we see that this is a low risk transaction given Northfield's conservative credit culture and experienced management team. The resulting exposure in commercial real estate will be well under 300% of capital. Our similar conservative credit cultures are evidenced by historically low nonperforming assets and charge-off histories of both banks. We've applied conservative credit and fair value marks supported by a thorough and detailed due diligence process with independent third parties, which Dennis Gibney will walk you through later in our presentation.
Pro forma earnings are projected to be approximately 1.06% return on average assets with pro forma earnings of $200 million, which is 51% accretive to our 2027 earnings per share and resulting in an efficiency ratio of approximately 48%. The resulting balance sheet features a loan-to-deposit ratio of approximately 96%, core deposits of 71%, cash and securities of 28%, and based on the of the independent appraisal for our proposed second step conversion, commercial real estate to total capital will be 211%.
We have long admired Northfield's relationship-driven approach to community banking and are excited to bring together two organizations with shared values, disciplined credit philosophies and a strong commitment to the communities we serve. Both institutions emphasize local decision-making, conservative risk management and long-term client relationships, creating a strong cultural and strategic fit. Northfield has built a high-quality deposit franchise, which we believe makes it an ideal partner for Columbia and creates a strong foundation for sustainable growth.
The combination diversifies Columbia's asset mix and reduces our reliance on long-term fixed rate residential mortgages, improving balance sheet flexibility. The transaction provides a median entry into two densely populated and economically diverse New York markets, Staten Island and Brooklyn, with combined deposit base of approximately $89.5 billion. With more than 1 million households in Brooklyn and approximately 174,000 households in Staten Island, the combined organization will be well positioned to leverage its mature digital banking capabilities, expanded product set and nationally recognized customer service to retain and expand and grow its customer base across these new entered markets.
Northfield's established market presence provides a platform to expand commercial and small business lending with, among other things, enhanced cash management and tenant security capabilities as well as new products and services, including insurance services to a broader customer base. These offerings align with the market's demonstrated growth in small business lending demand and the large professional and service-oriented population across both markets. Northfield has also built a commercially oriented franchise with a strong local reputation, reinforcing Columbia's ability to deepen client relationships, expand target fee-based businesses and drive disciplined relationship focused growth across two strategically important New York markets.
Our pro forma franchise will boast over 100 branches located in Brooklyn, Staten Island and the expansion in New Jersey. And the combined entity will result in Columbia being the fifth largest community bank deposit franchise in New Jersey while maintaining the #1 community-based franchise in Staten Island. We are very excited to combine our teams of like-minded community bankers.
I'd like to take -- turn this over to Steve Klein now to talk a bit about Northfield. Steve?
