Northfield Bancorp Shareholders Face July 10 Deadline to Elect Merger Consideration in Columbia Financial Deal

FAIR LAWN, N.J. — Columbia Financial, Inc. (NASDAQ: CLBK) and Northfield Bancorp, Inc. (NASDAQ: NFBK) announced on June 11, 2026, that they have mailed merger consideration election materials to Northfield stockholders, officially starting the clock on a critical decision point in their pending merger. Northfield shareholders now have until 5:00 p.m. Eastern time on July 10, 2026, to choose their preferred form of compensation for their shares.

This election deadline marks a critical juncture for Northfield shareholders. In our experience, the choice between cash and stock in a merger is not just about immediate value; it is a strategic decision reflecting an investor's long-term view of the combined entity, their personal tax situation, and their confidence in the new management's ability to realize projected synergies.

The materials give shareholders three options: receive a fixed number of shares in the newly formed holding company, accept a cash payment, or opt for a combination of both. The final value of the consideration is contingent on the final appraised value of Columbia Financial at the time the deal closes. According to a presentation filed with regulators, the deal structure has three tiers. If Columbia’s appraisal value is less than $2.3 billion, Northfield shareholders can elect to receive either 1.425 shares of Columbia common stock or $14.25 in cash for each of their shares. The consideration increases slightly if the appraisal comes in higher, topping out at 1.465 shares or $14.65 in cash if the appraisal value is $2.6 billion or more.

The merger agreement targets a consideration mix of approximately 70% stock and 30% cash. This means the final allocation is subject to proration. If the cash option is oversubscribed—meaning more than 30% of Northfield shares are submitted for cash—then shareholders who elected cash will receive a portion of their payment in cash and the remainder in Columbia stock. Conversely, if the stock option is oversubscribed, those shareholders will receive a mix of stock and cash. This proration mechanism introduces a level of uncertainty, as shareholders are not guaranteed to receive the exact form of consideration they elect.

The merger is the culmination of a larger corporate restructuring for Columbia Financial. The transaction is timed to occur immediately after Columbia completes its “second-step conversion” from a mutual holding company structure to a fully public, stock-owned corporation. Once the conversion is complete, Northfield Bancorp will merge into Columbia Financial, Inc., with Columbia surviving as the parent holding company. Immediately following that, Northfield Bank will merge into Columbia Bank, creating a single, larger banking institution under the Columbia Bank brand.

Navigating these complex M&A transactions, especially those involving conversions and tiered consideration, requires careful analysis. The proration risk alone means shareholders may not get the consideration they elect, which can significantly alter financial outcomes. This is precisely the kind of scenario where professional guidance is invaluable for business owners and individual investors alike.

The combined entity is set to become a significant regional player. Upon completion, the new Columbia Financial will hold approximately $18.1 billion in consolidated assets, making it the 110th largest insured depository organization in the United States, according to an order from the Federal Reserve. Regulatory reviews, including one by the Federal Reserve Board which approved the deal on May 8, 2026, concluded that the merger would not result in a significant reduction in competition in key markets such as the Metro New York City and Philadelphia areas, where both banks have operations.

The leadership structure for the post-merger bank has also been established. Columbia’s current President and CEO, Thomas J. Kemly, will continue to lead the combined holding company and bank. Northfield’s Steven Klein is slated to become Senior Executive Vice President and Chief Operating Officer, while Columbia’s Thomas Splaine will remain as Executive Vice President and Chief Financial Officer. This blend of leadership from both institutions is intended to ensure a smooth integration of operations.

The timeline for the deal has progressed steadily since its initial announcement on February 2, 2026. Key regulatory approvals were secured in May, paving the way for Columbia to commence its second-step conversion offering and now, the mailing of election forms to Northfield shareholders. The entire transaction is anticipated to close in the early third quarter of 2026, shortly after the July 10 election deadline passes.

Ultimately, for Northfield shareholders, this decision is a vote of confidence—or lack thereof—in the new combined management team and their strategy for integrating these two community banks into a larger regional player. The choice reflects a fundamental investment thesis on the future value creation potential of the merged institution.

Following the July 10 deadline, the companies will tabulate the shareholder elections and determine the final proration factors. The next key announcements will likely concern these final allocation results and the specific date on which the merger is legally completed. Until then, Northfield shareholders must weigh their options and submit their elections to the exchange agent before the deadline.
