Meridian Interstate Bancorp, Inc. Reports Net Income for the Third Quarter and
Nine Months Ended September 30, 2013

BOSTON, Oct. 22, 2013 (GLOBE NEWSWIRE) -- Meridian Interstate Bancorp, Inc.
(the "Company" or "Meridian") (Nasdaq:EBSB), the holding company for East
Boston Savings Bank (the "Bank"), which also operates under the name Mt.
Washington Bank, a Division of East Boston Savings Bank ("Mt. Washington"),
announced net income of $5.3 million, or $0.24 per diluted share, for the
quarter ended September 30, 2013 compared to $2.7 million, or $0.12 per
diluted share, for the quarter ended September 30, 2012. For the nine months
ended September 30, 2013, net income was $11.4 million, or $0.52 per diluted
share compared to $10.3 million, or $0.47 per diluted share, for the nine
months ended September 30, 2012. The Company's return on average assets was
0.83% for the quarter ended September 30, 2013 compared to 0.50% for the
quarter ended September 30, 2012. For the nine months ended September 30,
2013, the Company's return on average assets was 0.62% compared to 0.67% for
the nine months ended September 30, 2012. The Company's return on average
equity was 8.79% for the quarter ended September 30, 2013 compared to 4.70%
for the quarter ended September 30, 2012.For the nine months ended September
30, 2013, the Company's return on average equity was 6.35% compared to 6.05%
for the nine months ended September 30, 2012.

During the second quarter of 2012, the Company recognized a pre-tax gain of
$4.8 million on the sale of its investment in Hampshire First Bank, which was
43% owned by the Company, to NBT Bancorp, Inc. and NBT Bank, N.A.On an
after-tax basis, this one-time gain increased net income by $2.9 million, or
$0.13 per diluted share, for the nine months ended September 30, 2012.

Richard J. Gavegnano, Chairman and Chief Executive Officer, said, "I am
pleased to report net income of $5.3 million, or $0.24 per share, for the
third quarter and $11.4 million, or $0.52 per share, for the nine months ended
September 30, 2013. Our total assets have risen to over $2.6 billion due to
net loan growth of $326 million, or 18%, to $2.1 billion, and net deposit
growth of $340 million, or 18%, to $2.2 billion for the first nine months of
2013. This continuing growth demonstrates our ability to attract customers in
our Boston area markets with our banking products and services, particularly
loans and checking accounts. Following our expansion into the lucrative
markets of Belmont and Allston earlier this year, the November opening of our
27^th full service location in Somerville will further enhance our market
share and franchise value."

Net interest income increased $2.7 million, or 16.2%, to $19.1 million for the
quarter ended September 30, 2013 from $16.4 million for the quarter ended
September 30, 2012.The net interest rate spread and net interest margin were
3.02% and 3.17%, respectively, for the quarter ended September 30, 2013
compared to 3.12% and 3.29%, respectively, for the quarter ended September 30,
2012.For the nine months ended September 30, 2013, net interest income
increased $6.4 million, or 13.1%, to $55.0 million from $48.7 million for the
nine months ended September 30, 2012.The net interest rate spread and net
interest margin were 3.09% and 3.24%, respectively, for the nine months ended
September 30, 2013 compared to 3.25% and 3.42%, respectively, for the nine
months ended September 30, 2012.The increases in net interest income were due
primarily to loan growth along with declines in the cost of funds, partially
offset by declines in yields on interest-earning assets for the third quarter
and nine months ended September 30, 2013 compared to the same periods in 2012.

The average balance of the Company's loan portfolio increased $473.5 million,
or 29.6%, to $2.071 billion, which was partially offset by the decline in the
yield on loans of 37 basis points to 4.45% for the quarter ended September 30,
2013 compared to the quarter ended September 30, 2012.The Company's cost of
total deposits declined six basis points to 0.83%, which was partially offset
by the increase in the average balance of total deposits of $380.6 million, or
21.8%, to $2.123 billion for the quarter ended September 30, 2013 compared to
the quarter ended September 30, 2012.The Company's yield on interest-earning
assets declined 19 basis points to 4.02% for the quarter ended September 30,
2013 compared to 4.21% for the quarter ended September 30, 2012, while the
cost of funds declined nine basis points to 0.90% for the quarter ended
September 30, 2013 compared to 0.99% for the quarter ended September 30, 2012.

Mr. Gavegnano noted, "Since September of last year, strong growth of $492
million, or 30%, in our loan portfolio and $356 million, or 31%, in core
deposits contributed to our ninth consecutive quarterly rise in net interest
income. This continuing growth has moderated the declines in our net interest
margin despite falling loan yields."

The Company's provision for loan losses was $151,000 for the quarter ended
September 30, 2013 compared to $2.3 million for the quarter ended September
30, 2012.For the nine months ended September 30, 2013, the provision for loan
losses was $4.6 million compared to $5.8 million for the nine months ended
September 30, 2012. These changes were based primarily on management's
assessment of loan portfolio growth and composition changes, an ongoing
evaluation of credit quality and current economic conditions.In addition, the
reductions in the provision for loan losses reflected lower provision expense
related to specific reserves recorded for impaired loans for the third quarter
and nine months ended September 30, 2013 compared to the same periods in
2012.The allowance for loan losses was $23.7 million or 1.11% of total loans
outstanding at September 30, 2013, compared to $20.5 million or 1.13% of total
loans outstanding at December 31, 2012.Net recoveries totaled $79,000 for the
quarter ended September 30, 2013, or 0.02% of average loans outstanding, and
net charge-offs totaled $1.5 million for the nine months ended September 30,
2013, or 0.10% of average loans outstanding.

Non-performing loans increased $4.0 million, or 10.1%, to $43.6 million, or
2.04% of total loans outstanding, at September 30, 2013, from $39.6 million,
or 2.19% of total loans outstanding, at December 31, 2012, primarily due to a
net increase of $5.6 million in non-performing construction
loans.Non-performing assets increased $3.2 million, or 7.6%, to $45.4
million, or 1.71% of total assets, at September 30, 2013, from $42.2 million,
or 1.85% of total assets, at December 31, 2012.Non-performing assets at
September 30, 2013 were comprised of $13.4 million of construction loans, $9.0
million of commercial real estate loans, $17.2 million of one- to four-family
mortgage loans, $2.7 million of home equity loans, $1.3 million of commercial
business loans and foreclosed real estate of $1.8 million.Non-performing
assets at September 30, 2013 included $16.7 million of assets acquired in the
January 2010 Mt. Washington Co-operative Bank merger, comprised of $16.2
million of non-performing loans and $473,000 of foreclosed real estate.

Non-interest income increased $695,000, or 15.3%, to $5.2 million for the
quarter ended September 30, 2013 from $4.5 million for the quarter ended
September 30, 2012, primarily due to increases of $1.4 million in gain on
sales of securities, net, and $134,000 in loan fees, partially offset by a
decrease of $852,000 in mortgage banking gains, net.For the nine months ended
September 30, 2013, non-interest income decreased $2.8 million, or 16.2%, to
$14.3 million from $17.1 million for the nine months ended September 30, 2012,
primarily due to the prior year $4.8 million gain on sale of the Hampshire
First Bank affiliate and a decrease of $1.5 million in mortgage banking gains,
net, partially offset by increases of $3.5 million in gain on sales of
securities, net and $301,000 in customer service fees.The decreases in
mortgage banking gains, net are primarily due to declines in mortgage loans
sales along with related derivative valuations on commitments to originate
loans for sale and contracts to sell loans.

Non-interest expenses increased $1.2 million, or 8.5%, to $15.6 million for
the quarter ended September 30, 2013 from $14.4 million for the quarter ended
September 30, 2012, primarily due to increases of $1.4 million in salaries and
employee benefits, $221,000 in occupancy and equipment and $193,000 in data
processing, partially offset by decreases of $274,000 in professional
services, $239,000 in foreclosed real estate and $149,000 in other
non-interest expenses.For the nine months ended September 30, 2013,
non-interest expenses increased $3.0 million, or 6.8%, to $47.5 million from
$44.4 million for the nine months ended September 30, 2012, primarily due to
increases of $3.0 million in salaries and employee benefits, $546,000 in
occupancy and equipment expense, $574,000 in data processing, $276,000 in
marketing and advertising and $224,000 in deposit insurance, partially offset
by decreases of $839,000 in professional services reflecting a decline in
legal and consulting expenses, $333,000 in foreclosed real estate expense and
$402,000 in other non-interest expenses.The increases in salaries and
employee benefits and occupancy and equipment expenses were primarily
associated with the opening of new branches and costs associated with the
expansion of residential and commercial lending capacity.The Company's
efficiency ratio was 73.05% for the quarter ended September 30, 2013 compared
to 74.14% for the quarter ended September 30, 2012.For the nine months ended
September 30, 2013, the efficiency ratio was 76.62% compared to 77.93% for the
nine months ended September 30, 2012, excluding the gain on sale of the
Hampshire First Bank affiliate.

Mr. Gavegnano added, "We are progressively growing into our expanded lending
and core deposit funding capacity while we are becoming increasingly
efficient. Our efficiency ratio improved to 73.05% for the third quarter and
76.62% for the year-to-date, with net interest income rising at more than
twice the level of non-interest expenses so far this year. Although our costs
have increased at a moderate pace, our investments in staffing, infrastructure
and technology are resulting in increased market share and improved operating
profitability. We will continue to emphasize prudent management of our
overhead expenses as we grow."

The Company recorded a provision for income taxes of $3.3 million for the
quarter ended September 30, 2013, reflecting an effective tax rate of 38.1%,
compared to $1.6 million, or 36.4%, for the quarter ended September 30,
2012.For the nine months ended September 30, 2013, the provision for income
taxes was $5.8 million, reflecting an effective tax rate of 33.8%, compared to
$5.3 million, or 33.7%, for the nine months ended September 30, 2012.The
change in the effective tax rate was primarily due to changes in the
components of pre-tax income.

Total assets increased $376.2 million, or 16.5%, to $2.655 billion at
September 30, 2013 from $2.279 billion at December 31, 2012.Net loans
increased $326.1 million, or 18.3%, to $2.112 billion at September 30, 2013
from $1.786 billion at December 31, 2012.The net increase in loans for the
nine months ended September 30, 2013 was primarily due to increases of $177.4
million in commercial real estate loans, $103.1 million in multi-family loans,
$19.7 million in construction loans and $32.9 million in commercial business
loans.Cash and cash equivalents increased $113.0 million, or 121.3%, to
$206.2 million at September 30, 2013 from $93.2 million at December 31,
2012.Securities available for sale decreased $57.9 million, or 22.0%, to
$204.9 million at September 30, 2013 from $262.8 million at December 31, 2012.

Total deposits increased $339.7 million, or 18.2%, to $2.205 billion at
September 30, 2013 from $1.865 billion at December 31, 2012, including net
growth in core deposits of $280.9 million, or 22.7%, to $1.518 billion, or
68.8% of total deposits.Total borrowings increased $26.4 million, or 16.4%,
to $187.7 million at September 30, 2013 from $161.3 million at December 31,
2012.

Total stockholders' equity increased $9.7 million, or 4.1%, to $243.7 million
at September 30, 2013, from $233.9 million at December 31, 2012.The increase
for the nine months ended September 30, 2013 was due primarily to $11.4
million in net income, partially offset by a decrease of $1.6 million in
accumulated other comprehensive income reflecting a decrease in the fair value
of available for sale securities, net of tax and a $1.6 million increase in
treasury stock resulting from the Company's repurchase of 91,086
shares.Stockholders' equity to assets was 9.18% at September 30, 2013,
compared to 10.27% at December 31, 2012.Book value per share increased to
$11.04 at September 30, 2013 from $10.57 at December 31, 2012.Tangible book

at September 30, 2013 from $16.78 at December 31, 2012.At September 30, 2013,
the Company and the Bank continued to exceed all regulatory capital
requirements.

stock at an average price of $14.68 per share, or 31.8% of the 904,224 shares
