5 Executive Summary 3 Blue Hill’s Preliminary Indication of Interest is Illusory, Non-Binding and Highly Conditional — Exposing Territorial Shareholders to Significant Uncertainty and Downside Risk Highly conditional ❌ No committed financing ❌ Requires side agreements with undisclosed terms to be negotiated and signed by numerous unidentified investors ❌ Subject to due diligence ❌ Dependent on overcoming significant hurdles in a regulatory process that is not yet started and would be difficult Territorial's stock could be worth substantially less than it is today if Blue Hill Gains Control of the Company ❌ In the highly unlikely event Blue Hill is able to complete a full tender, Territorial shareholders could be left with illiquid, unlisted, stub minority investment in a company controlled by an undisclosed Board and management team and undisclosed governance policies ❌ If Blue Hill transaction is not completed, shareholders left with investment in a company that faces meaningful business and value downside risks ❌ Undisclosed investors – who would control the Company – have provided no assurance that they would serve all shareholders’ interests and have not defined a governance structure that ensures they do ❌ Tax consequences potentially leave shareholders with less – in some cases substantially less – than $12.50 per share Proposed terms transfer value from shareholders to Blue Hill ❌ Warrants provided to Blue Hill’s undisclosed investors lack transparency and could create significant dilution for Territorial shareholders ❌ Territorial required to reimburse Blue Hill and its undisclosed investors for expenses they incurred to make their proposal Just trust us. We have "capital support” – is not committed financing.

1. As of Jun 30, 2024 6 Executive Summary 4 Blue Hill’s Preliminary Indication of Interest is Illusory, Non-Binding and Highly Conditional — Exposing Territorial Shareholders to Significant Uncertainty and Downside Risk Significant Uncertainty that Blue Hill Can Complete the Transaction at All Blue Hill’s cloak of anonymity creates substantial regulatory risk and uncertainty ❌ As it currently stands, regulators would be faced with a decision on whether to allow an undisclosed investor group undisclosed Board and undisclosed management team to gain control of a financial banking institution charged with overseeing $1.57B in deposits1 ❌ Regulators would require from Blue Hill a detailed business plan, including specifics on Board, management, strategy, resources, capital planning, policies and procedures. No such plan has been shared with Territorial’s Board. Does such a plan exist at all? Blue Hill is not a well-known entity and appears to lack M&A and regulatory experience with transactions of this size and complexity ❌ Blue Hill was only established in February of 2023 ❌ According to public sources, its legal registered business address appears to be a residential home in Hudson, New York (see slide 7) ❌ No evidence that Blue Hill, its named principals nor its undisclosed investors have obtained – or even tried to obtain – regulatory approval for a transaction of this size and complexity Achieving the required tender threshold is highly unlikely ❌ Based on advice from a leading proxy solicitation firm whose principals have overseen hundreds of tender offers over the past 40+ years, it is highly unlikely that Blue Hill could meet its required tender threshold given the composition of Territorial’s shareholder base ❌ A transaction without regulatory approval and a failed tender offer would leave Territorial facing two failed deals and significant standalone business risks

7 1. Per the LLC entity information filed with New York State 2. https://www.apartments.com/286-blue-hill-rd-hudson-ny/y5jxrls/ Executive Summary 5 Blue Hill’s Preliminary Indication of Interest is Illusory, Non-Binding and Highly Conditional — Exposing Territorial Shareholders to Significant Uncertainty and Downside Risk ❌ In press reports and elsewhere, Blue Hill repeatedly emphasizes “local management,” but: ❌ None of its named principals appear to primarily reside in Hawaiʻi, according to public information ❌ Blue Hill is not based in Hawaiʻi. Its registered business address1 is a residential home in Hudson, New York, which is also for rent2 on apartments.com ❌ Blue Hill has failed to disclose who would comprise its Board and management team after it gains control of Territorial ❌ Blue Hill has provided no assurances as to whether it would reduce employment levels, change employee compensation or benefits, or reduce investments in communities after it gains control of Territorial ❌ Reduced business transparency since Territorial would likely not be an SEC reporting entity and there is uncertainty regarding whether Territorial would remain listed on NASDAQ ❌ In order for Blue Hill to reach its targeted 55% efficiency ratio, there would likely need to be significant job cuts and reduced investments in areas such as technology ❌ Short-term investment horizon or potential quick flip of the Company? Reducing Territorial’s one- to four-family loan portfolio from 97% to 80% in such a short time frame as Blue Hill has proposed would be difficult to achieve without selling Territorial’s residential loans at a loss Blue Hill Unlikely to Deliver Its Claimed Benefits to Hawaiʻi. Rather, it Could be Detrimental to Hawaiʻi, Jobs and Communities. A new entity formed in 2023, Blue Hill’s registered business address is a home in New York: 286 Blue Hill Road Hudson, NY 12534

8 Shareholders Should Ask: Why is Blue Hill not providing a financing commitment letter? Why is Blue Hill not disclosing the names of the investors who are supposedly backing its indication of interest? Why is Blue Hill not disclosing the terms of the side agreement it has reached with its undisclosed investors? Why is Blue Hill not disclosing who it will appoint to its reconstituted Board and management team after it takes control? Why is Blue Hill not disclosing the amount of legal, accounting, placement agent fees it will require Territorial shareholders to pay to Blue Hill and unnamed investors after Blue Hill takes control? Why should Territorial’s shareholders be responsible for paying their expenses at all? Is Blue Hill aware they may have additional capital requirements? If Blue Hill was interested in a friendly, negotiated transaction that serves the interests of all Territorial shareholders and stakeholders, why didn’t Blue Hill previously express interest in Territorial as other companies did? Why did it wait until after a definitive agreement with Hope Bancorp was already signed? If Blue Hill and its undisclosed investors are so sophisticated in M&A and banking transactions, why do they need Territorial to determine whether their indicated transaction would qualify for a recapitalization (and not purchase) accounting treatment? Is Blue Hill aware of the required regulatory approvals? What would life be like as a minority stub investor in a challenged company that is controlled by an unnamed, unknown Board and management team that has no governance policies to ensure all shareholders’ best interests are served? If Blue Hill has sufficient resources to complete the transaction, why is it insisting that Territorial pay its expenses? How would Territorial recover its expenses and the likely drop in its stock price if Blue Hill fails to close its proposed transaction? ? ? ? ? ? ? ? ? ? ? ? ?

22 Standalone Territorial Continues to Face a Difficult Operating and Regulatory Environment, Which is Mitigated by the Hope Bancorp Combination. In Contrast, a Blue Hill Transaction Would Not Address these Issues Single-Product Franchise Presents Risk ~97% of Territorial's loan portfolio consists primarily of one- to four-family loans Given Territorial’s liability sensitive position, the Company must carry stronger tangible capital to help offset interest rate risk This compares to more traditional community bank peers, which report tangible common equity/tangible assets on a median basis of 8.4% With its lower credit risk portfolio, Territorial is also able to carry loan loss reserves/loans of 0.39% v. more traditional community bank peers who report the same ratio at a median level of 1.18% Any change to the business plan of Territorial could require the bank to carry more loan loss reserves impacting future earnings

23 Heightened regulatory scrutiny as a monoline, one-to-four-family loan focused bank ❌ Earnings dependent on undiversified portfolio which involves significant interest rate risk ❌ Longer term loans carry more interest rate risk, which require more capital ❌ Capital constraints constrict growth “Regulators and rating agencies have long been wary of “monoline banks”—those that fixate on one sector or industry—regardless of which industry that happens to be, since, by definition, they will lack risk diversification." Mar 15, 2023 “These current mortgage markets are what make it challenging for independent mortgage banks (IMBs). For many of these transaction-oriented, monoline mortgage lenders, it’s always a question of feast or famine...During the extended period of artificially low interest rates, these institutions became the leaders of the online, streamlined rate-and-term refinance transaction. In addition, they were leaders in originating FHA, VA and USDA loans. As a result, the IMB sector saw significant growth, but that specialization would prove to be a risk embedded in their business model."

However, with the recent decline in rates, there is some hope for production to increase, though statewide inventory remains very low” Jan 29, 2024 …The Value Created By the Hope Bancorp Merger… …The Benefits for Territorial’s Stakeholders… “Since Bank of Hope does not currently operate in Hawaii, the bank can retain almost all employees at Territorial after the acquisition, and all branding will remain intact for the regional bank.” May 13, 2024 …And Territorial’s Risks as a Standalone Organization – Even if Interests Rates Decline “TBNK declared a quarterly dividend of $0.01/share, representing an 80% cut relative to the prior $0.05/share” May 13, 2024 “EOP loan balances declined 4.4% LQA and average loan balances -4.5% LQA. Average loans in 2Q were $13.6B versus $14.1B in the fourth quarter of 2023, with the company's 2024 guidance pointing to low single-digit average loan growth in 4Q24 vs. 4Q23. Getting back to flat Y/Y would require a near 7% annualized growth rate over the next two quarters; our $13.9B estimate represents a 5% annualized pace” Jul 29, 2024 “At the time of announcement, the deal valued TBNK shares at $8.82/share, which represented a 25% premium to the pre-announcement closing price, 31% of TBV and 16.0x our 2025 EPS estimate” May 6, 2024 “Accessing a new market and obtaining low-cost funding are beneficial to Hope, and gaining access to a larger balance sheet will be an advantage for Territorial, so that it can offer bigger loans and serve different types of clients.” Apr 29, 2024 Research Analyst at Research Analyst at Research Analyst at Research Analyst at Research Analyst at

1. Federal Home Loan Bank system 27 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests No detail or data to validate Blue Hill’s restructuring strategies Blue Hill intimates that it would sell $300M of securities to pay down FHLB1 borrowings. These securities, from an accounting perspective, are held to maturity Selling underwater securities could result in a loss and potentially taint the rest of Territorial’s portfolio, which would also require Territorial to provide a fair value calculation on the entire securities book Blue Hill also states that, over the next five years, the loan portfolio would reprice 30% higher despite current lower interest rate outlook Blue Hill’s Loan Repricing Hopes are Unrealistic

28 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests Blue Hill Far Underplays the Significant Obstacles it Faces in Achieving Regulatory Approval SIGNIFICANT REGULATORY APPROVAL UNCERTAINTY (FEDERAL RESERVE REGULATION) Individual investors who own (or deemed to own or control, when deemed to be “acting in concert” with others) 10% or more of the voting interests will need approval or non-objection from Federal Reserve Board. Individual investors who own (or deemed to own or control, when deemed to be “acting in concert” with others) 25% or more of the voting interests will need to obtain approval from the Federal Reserve Board. Business entities that own (or deemed to own or control, when deemed to be “acting in concert” with others) 25% or more of the voting interests will be required to become a “bank holding company” and be approved by and registered with the Federal Reserve Board. Any issuer tender offer, and corresponding reduction in capital, will require the approval of the Federal Reserve Board and, if the bank projects losses, will likely not receive such approval unless additional new capital is injected into the bank. The top two “control” persons (typically, the new CEO and person who is the largest controlling stockholder or the Chairman or CFO) will also be subject to Federal Reserve Board and Hawaii DCCA approvals and will be required to file “Individual Biographical and Financial Reports” (IBFRs), which require the submission of substantial information regarding control persons including financial statements, employment history, regulatory history and litigation history. These “control” persons would also need to submit to background checks. “Acting in concert” includes knowing participation in a joint activity or parallel action towards a common goal of acquiring control of a covered institution whether or not pursuant to an express agreement. Blue Hill has not addressed how it or its unidentified board, unidentified management team and unidentified investors will surmount any of these substantial regulatory hurdles before it can close its proposed transaction. No information or assurances have been provided as to how Blue Hill will avoid being deemed to be “acting in concert” with the other investors and subject itself to additional “bank holding company” scrutiny and operating limitations. No evidence of any regulatory analysi s, pre-filing meetings or any regulatory contact regarding satisfaction of the hurdles has been provided. SIGNIFICANT REGULATORY APPROVAL UNCERTAINTY, HAWAI‘I (HI STATUTES §§412:3-612 AND 412:1-109) No person may acquire “control,” directly or indirectly, individually or in concert with another, of a Hawai‘i bank unless approved by the Hawaii Commissioner. “Control” is owning or controlling 10% or 25% of the voting interests depending on the facts and circumstances, and taking into consideration whether such persons are “acting in concert” as determined by the Commissioner. x No detailed business plan, which would be required from regulators in a change-in-control transaction, including ▪ Realistic forecast of market demand, customer base, competition, economic conditions ▪ Sound banking principles and realistic assessment of risk in light of economic and competitive conditions in the market to be served ▪ An institution with a special purpose or focus (for example, credit card, trust only, cash management, or bankers’ bank) should address this special or unique feature in detail in the appropriate sections of the plan x Undisclosed Board x Undisclosed management team x No acknowledgement that in addition to approval from Federal Reserve Board, approval is also required from Hawaiʻi banking regulators x No acknowledgement that Territorial Savings Bank will need an additional capital infusion – beyond its indicated purchase price – in order for Blue Hill to complete the tender if the bank projects losses, as Territorial does today, or if there is a change in strategy ▪ Blue Hill has not substantiated where these funds will come from or if they are even able to provide them LACK OF DETAIL IN BLUE HILL MATERIALS SUGGESTS THAT IT HAS NO EXPERIENCE WITH TRANSACTION OF THIS SIZE AND COMPLEXITY

29 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests Moreover, the AUM cited by Blue Hill isn’t even for Blue Hill. Just trust us. We have “capital support” is not committed financing. AUM has nothing to do with the ability to finance a transaction. Despite repeated statements from Territorial that the absence of committed financing is a key factor in the Board’s determination that the Blue Hill indication of interest is not a superior proposal, or reasonably like to lead to a superior proposal, Blue Hill has still not provided proof of committed financing.

30 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests Blue Hill Says… But in reality… Backed by “seasoned” bank investors ❌ Blue Hill has declined to disclose who its numerous investors are and the terms of the side agreement they require to provide funding for any transaction ❌ Blue Hill has not disclosed the Board and management team who would lead its controlled company ❌ Only one of the three Blue Hill individuals named in its materials has meaningful regional and community bank management experience We have received “dozens” of regulatory approvals We have a “less onerous” regulatory review process ❌ Blue Hill has not applied for — nor secured — regulatory approvals for any transaction of this size based on information it has provided to Territorial ❌ Blue Hill has not applied for — nor secured — any regulatory approvals in connection with this transaction based on information it has provided to Territorial ❌ Blue Hill far underplays the significant obstacles it faces in achieving regulatory approvals on a timely basis, if at all (see slide 28)

31 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests Blue Hill Says… But in reality… Our proposal would enable “up to 30%” of existing shareholders to remain investors Remaining Territorial investors would be left with: ❌ A stub minority investment with a controlling shareholder who has made no commitment to serving all shareholders’ best interests ❌ No voting influence given Territorial would be a controlled company ❌ An investment in a company that faces the same challenges that Territorial faces today ❌ Limited liquidity given small public float and uncertainty regarding whether Territorial would remain listed on NASDAQ The Hope Bancorp merger gives away Territorial “recovery” opportunity ❌ If its tender is fully executed, Blue Hill’s cash-based consideration would eliminate the opportunity for Territorial's shareholders to remain investors ❌ It is the Hope Bancorp merger that accelerates Territorial’s recovery

32 Blue Hill’s Non-Binding, Preliminary Indication of Interest is Illusory, Highly Conditional and Not in Territorial Shareholders’ Best Interests Blue Hill Says… But in reality… Virtually nothing on the tax and accounting implications of its proposal ❌ While Blue Hill says it will not need to use purchase accounting, immediately selling securities at fair value and taking an equity write-down is essentially the same thing ❌ Blue Hill’s cash-based transaction would be taxable for Territorial’s shareholders ❌ Tax consequences associated with Blue Hill’s proposed cash structure potentially leave shareholders with less – in some cases substantially less – than $12.50 per share It will "expand product offerings" ❌ As a small bank with limited scale compared to local competitors, the investment opportunities are significantly limited ❌ Hope Bancorp merger will significantly expand Territorial's offerings through addition of Hope Bancorp's broad portfolio ❌ Blue Hill has not acknowledged that Territorial Savings Bank will need an additional capital infusion – beyond its indicated purchase price – in order for Blue Hill to complete the tender if the bank projects losses, as Territorial does today, or if there is a change in strategy. Nor does Blue Hill provide information about where this additional capital will come from

33 Territorial Board Unanimously Believes Hope Bancorp Merger is in Territorial Shareholders’ Best Interests ❌ No committed financing ❌ Blue Hill’s cloak of anonymity creates substantial regulatory risk and uncertainty ❌ Blue Hill is not a well-known entity and appears to lack M&A and regulatory experience with transactions of this size and complexity ❌ Achieving the required tender threshold is highly unlikely ❌ Illusory value could be substantially less than $12.50 per share even if the transaction could actually be completed ❌ Proposed terms transfer value from shareholders to Blue Hill ❌ Blue Hill unlikely to deliver its claimed benefits to Hawaiʻi; rather, its transaction could be detrimental to Hawaiʻi jobs and communities Territorial + Hope Bancorp Compelling Combination Blue Hill’s Preliminary Indication of Interest is Illusory, Non-Binding and Highly Conditional ✓ Results from competitive, multi-month process ✓ Provides significant value to Territorial shareholders ✓ Enables Territorial shareholders to participate in substantial upside opportunity created by combined company ✓ Preserves Territorial’s unwavering commitment to Hawaiʻi, customers, employees, communities ✓ Mitigates the difficult operating and regulatory environment that Territorial faces as a standalone company Territorial Board Unanimously Recommends that Territorial Shareholders Vote FOR Hope Bancorp Merger
