 - STRENGTHS –  5  An asset-generation machine in NYC multifamily market.Legacy relationships with NYC brokers and borrowers.Experienced and knowledgeable executives and directors, and core team members.Historically low operating expenses, a hallmark of the company.Historically low credit cost due to performance of the asset class.Historically high returns relative to the thrift peer group.NATIONWIDE BRAND RECOGNITION as a result of Dime’s iconic brand logo, it’s longevity and authenticity.Top-rated regulatory, compliance and credit administration practices.Excess capital, plus significant addition to capital anticipated in 2Q2017 from bank-owned property sale.Ranked #5 in SNL 2015 High Performing Thrift Rankings. 

 - CHALLENGES –identified in January 2014 situational review  6  Bring small business focus to the brick-and-mortar channel.Reduce the high level of loans-to-deposits (150%+ as of Jan 2014), and decrease reliance on FHLB borrowings.Improve the level of non-spread revenue.Increase the percentage of quality deposits (non- and low-interest bearing) to total deposits.Re-stock the executive team; focus on diversity recruitment in the ranks of middle and executive management.Invest heavily in people acquisition, training, development.Establish stronger link between incentive compensation and the P&L; improve profitability measurement tools.Upgrade technology.Adopt commercial bank model more suited to today’s financial marketplace. 

 - OPPORTUNITIES – identified in January 2014 situational review  7  $50 million capital gains to be available from sale of Williamsburg, Brooklyn, properties in 2016 and 2017, representing the equivalent of an 11% capital raise, without diluting shareholders.Executive retirements freeing up salary cap space.Located in the most densely populated market in the world.Enormous marketplace of small businesses and professionals located within the bank’s brick-and-mortar footprint.Bank consolidation leading to increased availability of talented managers and operators.Rapidly declining cost of, and meaningful improvements in, customer-facing and process-improving technologies.Customers eager and willing to patronize internet-based financial service providers. 

 - THREATS –   8  Regulatory risk to Dime’s traditional multifamily model from regulatory focus on “concentration risk”.Dime has a CRE concentration, mainly in NYC multifamily residential loans, generally rent-regulated or moderate rent apartments which, for concentration purposes, are aggregated just like construction loans Nevertheless, Dime’s concentration in this asset class helped the bank avoid any meaningful level of loan losses throughout the financial crisis.Operating expenses: how to absorb new cost burdens while maintaining a best-in-class operating expense ratio?JP Morgan Chase: Since the financial crisis, Chase has focused on the NYC multifamily asset class as a source of high quality loans, and has targeted Dime’s market niche: multifamily loans with an average size of $2 million(1), creating a powerful new competitor.FinTech: The internet has enabled new companies and old alike, to market to the consumer mass financial services market, thereby eroding the competitive advantage provided by brick-and-mortar community banks.  (1) KBW Research Report: NYC Multifamily Lending: A Look at JPM’s Plan to Disrupt the Market and Grow, February 28, 2017

 Evolution to a community commercial bank  15  In January 2017, members of the former team of Community National Bank, Great Neck, LI, joined DIME along with former CEO Stu Lubow.Dime adds “direct lending/relationship banking” to its powerful “indirect/broker driven” lending platform.Small business loans, SBA loans, and eventually consumer credit, will be added to the DIME menu of available credit products.Several relationship banking teams have already joined DIME, and new offices are opening in Melville, Long Island, and midtown Manhattan to service existing and new clients.This buildout brings a fearless focus on building a strong, commercial bank-like deposit base. 

 The Market & Dime’s Foray into Digital:DimeDirect  Digital Banking Personal banking revenues in the U.S. rose 3% to ~$600B between 2010 and 2015, and are expected to grow at 5% through 2020.Investments in digital, or pure-play direct banks and lenders are growing at a rate 2x that of traditional / hybrid banks – with significantly lower legacy costs.Digital-first integrated personal banking is largely an unmet gap in the market.Consumers are increasingly comfortable with using mobile and web-based technologies for banking.Among Internet, mobile, and physical banking channels, only the mobile channel has experienced an increase in customers using the channel at least once weekly.  Dime’s ExperienceRelatively low cost acquisition of ~$1B in deposits.Customer base is demographically diverse, with an average balance size of over $100K, suggesting significant opportunities for cross-sell.Over one-third of the acquired base is in our branch trading area.Dime Direct has enabled Dime to broaden its appeal to millennials and out-of-market customers.Balance run-off has been extremely low.Client retention is > 90%.Zero fraud losses to date.  16 

 Dime’s Deposit Growth Far Exceeded Other Banks  While traditional banks’ deposit growth has been 6% on average over the last 5 years, Dime’s deposit growth in 2016 exceeded 38%   Traditional Banks ($B)  Dime Deposit Growth  Direct Banks ($B)  +38%  17  Source: Company reports.

 Key Challenges & Opportunities  No other products offered online, so low-cost cross-sell via online is unavailable.Online account opening and enrollment for transfer capabilities are separate processes requiring multiple verification steps, making funding and transfers a clunky experience.Retention drivers, such as bill pay, direct deposit, or debit cards, are also unavailable or of limited usability (6 transaction limit on MM).   CHALLENGES    OPPORTUNITIES   Twenty-four percent of customers are from NY, and over one-third from the tri-state area, which suggests cross-sell via phone or branch might be viable.Thirty-two percent of customers are under 44, which demonstrates the Dime brand can engage millenials; with a more robust product set online, it is likely to retain these customers .Trust products have been a frequent request into the call center, which is a reflection of the higher wealth of a significant portion of the base, and suggestive of an opportunity for expansion into wealth management.  19 

 Retention  Attrition has been relatively low. At 1.10%, Dime’s rate is near the national leaders. However, the top tier competitors have so far shown little appetite to raise rates with this early move upward by the Federal Reserve.  20  Jan  Mar  Apr  Feb  May  Jun  Jul  Aug  Sep  Oct  Nov  Dec  Note: Percentages above each bar represent customer retention rates.
