Exhibit 99.1

RELEASE 8:00 AM – April 29, 2015

HUDSON CITY BANCORP, INC. REPORTS QUARTERLY EARNINGS OF $5.9 MILLION

Paramus, New Jersey, April 29, 2015 - Hudson City Bancorp, Inc. (NASDAQ: HCBK) (the “Company”), the holding company for Hudson City Savings Bank (the “Bank”), reported today net income of $5.9 million for the quarter ended March 31, 2015 as compared to net income of $42.5 million for the quarter ended March 31, 2014. Diluted earnings per share amounted to $0.01 for the quarter ended March 31, 2015 as compared to diluted earnings per share of $0.09 for the quarter ended March 31, 2014.

The Company’s Board of Directors (the “Board”) did not declare a dividend for the first quarter of 2015. The Board made this decision after considering the level of earnings for the first quarter, the importance of paying dividends out of current earnings and the regulatory evaluation of any dividend request. The Company is required to seek regulatory approval prior to declaring a dividend.

Net income for the quarter reflects the continued decrease in the Company’s net interest margin that is the result of our elevated level of low-yielding short-term liquid assets combined with our high-cost borrowings. Over the last several quarters, we have managed our balance sheet on a dual-track strategy which includes the implementation of our strategic plan initiatives and preparing for the completion of the merger (the “Merger”) with M&T Bank Corporation. The operational core of the strategic plan includes the expansion of our loan and deposit product offerings over time and the diversification of our revenue sources. The strategic plan also includes a balance sheet restructuring transaction that would significantly increase our net interest margin and net income by extinguishing approximately $12 billion of borrowings that have a weighted average cost of 4.59%. We would extinguish these borrowings primarily with the short-term liquid assets that are currently on our balance sheet as well as new borrowings with significantly lower rates. At March 31, 2015, short-term liquid assets, consisting of overnight funds and U.S. Treasury securities, amounted to $10.2 billion with a weighted average yield of 0.26%. While we expect that the restructuring transaction would result in a material charge to earnings, we believe that the restructuring would increase our net interest margin by as much as 180 basis points depending on the timing of the execution and the prevailing rates at that time. The delay in the execution of the balance sheet restructuring and our continuing to carry an excess liquidity position is primarily due to the delay in completing the Merger, though a variety of factors are involved in the decision regarding any such restructuring.

During 2014, we supplemented our earnings with gains on the sales of securities. This strategy was key to maintaining earnings despite a decreasing net interest margin as rates remained low and we continued to carry excess liquidity with very little appetite for reinvesting this liquidity into longer-term investments or fixed-rate residential mortgage loans. In addition, the market demand and prices provided a strong opportunity for us to sell these securities. However, in anticipation of the closing of the Merger, which was expected to close on May 1, 2015, we suspended the sale of securities during the first quarter. Unfortunately, the unexpected news in early April that there would be a further delay in completing the Merger came too late for us to resume the sale of securities before the end of the first quarter and, as a result, our net income was adversely affected. As we enter the second quarter, we expect to resume our strategy of supplementing our earnings with securities sales. To facilitate these securities sales, in the second quarter of 2015 we transferred our held-to-maturity securities to available-for-sale.

Denis J. Salamone, Chairman and Chief Executive Officer, commented, “This has certainly been a challenging quarter for us. The latest unexpected delay in the Merger contributed to the first quarter’s weak earnings. We believe future earnings can be improved significantly in the short-term by a balance sheet restructuring and in the longer-term by execution of the other strategic initiatives. However, both of these actions are complicated by the pendency of the Merger.”

Mr. Salamone continued, “We firmly believe that the M&T transaction remains financially attractive to Hudson City’s shareholders, and that continuing to pursue completion is in the best interest of Hudson City and the communities we serve. As a result, we remain committed to the Merger. Assuming market conditions remain stable, we anticipate additional margin compression during the pendency of the Merger, but securities gains that are more in-line with those of the fourth quarter of 2014.”

Mr. Salamone concluded, “On a final note, we are very pleased that during the first quarter the Office of the Comptroller of the Currency (“OCC”) terminated the memorandum of understanding (“MOU”) entered into with the Bank on March 30, 2012. In the course of satisfying the terms of the MOU, the Bank, among other things, developed an enterprise risk management department as part of a “three lines of defense” organizational structure and implemented enhanced risk management policies, procedures and systems. We believe these accomplishments, along with our strong ethical corporate culture, provide Hudson City with the necessary governance structure and risk management framework to meet the challenges facing all financial institutions in this current environment. I am particularly proud of the efforts of our employees to complete the work necessary to satisfy the requirements of the MOU during the pendency of the Merger.”

Financial highlights for the first quarter of 2015 are as follows:

Statement of Financial Condition Summary

Total assets decreased $439.8 million, or 1.2%, to $36.13 billion at March 31, 2015 from $36.57 billion at December 31, 2014. The decrease in total assets reflected a $758.4 million decrease in net loans, a $399.1 million decrease in total mortgage-backed securities and a $113.0 million decrease in cash and cash equivalents, partially offset by an $807.8 million increase in investment securities.

Total cash and cash equivalents decreased $113.0 million to $6.17 billion at March 31, 2015 as compared to $6.29 billion at December 31, 2014. The high level of cash and cash equivalents is primarily due to repayments on mortgage-related assets and our limited appetite for reinvesting these funds in low-yielding longer-term assets. We have maintained lower deposit rates to allow a reduction in our deposits to help manage deposit levels at a time when there are limited investment opportunities and to prepare for a balance sheet restructuring during 2015. We have used a portion of our excess cash inflows to fund these deposit reductions.

Net loans decreased to $20.67 billion at March 31, 2015 as compared to $21.43 billion at December 31, 2014 due primarily to a decrease in loan production. During the first quarter of 2015, our loan production (originations and purchases) amounted to $184.5 million as compared to $298.3 million for the fourth quarter of 2014. Loan production was offset by principal repayments of $910.4 million during the first quarter of 2015, as compared to principal repayments of $872.0 million for the fourth quarter of 2014. Beginning in the fourth quarter of 2014, the Bank began to purchase commercial real estate loans and commercial real estate loan participations, which is one of the initiatives in the Company’s Strategic Plan. During the first quarter of 2015, the Bank purchased $25 million of such loan participations as compared to $86.6 million for the fourth quarter of 2014, for an aggregate of $112 million.

The decline in loan production during the first quarter of 2015 as compared to the fourth quarter of 2014 reflects our limited appetite for adding long-term fixed-rate mortgage loans to our portfolio in the current low market interest rate environment.

Total mortgage-backed securities decreased $399.1 million to $3.84 billion at March 31, 2015 from $4.24 billion at December 31, 2014. The decrease was due primarily to securities sales of $218.6 million and repayments of $181.4 million of mortgage-backed securities during the first quarter of 2015. We sold mortgage-backed securities during 2014 and the first quarter of 2015 to take advantage of market demand and prices. The proceeds from the sales have been invested primarily in short-term liquid assets. While this further increases our levels of low-yielding liquid assets, we believe this positions our balance sheet for a potential balance sheet restructuring transaction.

Total investment securities increased $807.8 million to $4.46 billion at March 31, 2015 as compared to $3.65 billion at December 31, 2014. The increase was due primarily to purchases of $800.8 million of U.S. Treasury securities with an average life of 11 months which are used as collateral for our outstanding borrowings.

Total liabilities decreased $439.3 million, or 1.4%, to $31.35 billion at March 31, 2015 from $31.79 billion at December 31, 2014. The decrease in total liabilities reflected a decrease in total deposits while total borrowed funds remained unchanged.

Total shareholders’ equity was $4.78 billion at both March 31, 2015 and December 31, 2014. Cash dividends paid to common shareholders during the first quarter of 2015 amounted to $20.0 million partially offset by a change in accumulated other comprehensive loss of $8.5 million and net income of $5.9 million. At March 31, 2015, our consolidated shareholders’ equity to asset ratio was 13.23% and our tangible book value per share was $9.25.

Accumulated other comprehensive loss amounted to $41.9 million at March 31, 2015 and included a $67.6 million after-tax accumulated other comprehensive loss related to the funded status of our employee benefit plans partially offset by a $25.7 million after-tax net unrealized gain on securities available for sale ($43.4 million pre-tax). Accumulated other comprehensive loss amounted to $50.4 million at December 31, 2014 which included a $68.7 million after-tax accumulated other comprehensive loss related to the funded status of our employee benefit plans partially offset by a $18.3 million after-tax net unrealized gain on securities available for sale ($30.9 million pre-tax).

Statement of Income Summary

The Federal Open Market Committee of the Board of Governors of the Federal Reserve System (the “FOMC”) noted that economic growth has moderated somewhat during the first quarter of 2015. The FOMC noted that labor market conditions have improved further with strong job gains and a lower unemployment rate. A range of labor market indicators suggests that underutilization of labor resources continues to diminish. Household spending is rising moderately and business fixed investment is advancing, while the recovery in the housing sector remains slow. The national unemployment rate decreased to 5.5% in March 2015 from 5.6% in December 2014 and from 6.6% in March 2014. The FOMC decided to maintain the overnight lending target rate at zero to 0.25% during the first quarter of 2015.

The FOMC stated that it is maintaining its existing policy of reinvesting principal payments from its holdings of agency debt and agency mortgage-backed securities in agency mortgage-backed securities and of rolling over maturing Treasury securities at auction. The FOMC believes this policy of keeping holdings of longer-term securities at sizable levels should help maintain accommodative financial conditions.

Net interest income decreased to $75.6 million for the first quarter of 2015 as compared to $87.2 million for the linked fourth quarter of 2014 and $132.3 million for the first quarter of 2014 reflecting the overall decrease in the average balance of interest-earning assets and interest-bearing liabilities, the continued low interest rate environment and a continued increase in the average balance of short-term liquid assets, including U.S. Treasury securities and Federal funds sold and other overnight deposits. Our interest rate spread decreased to 0.53% for the first quarter of 2015 as compared to 0.70% for the linked fourth quarter of 2014 and 1.12% for the first quarter of 2014. Our net interest margin was 0.85% for the first quarter of 2015 as compared to 1.01% for the linked fourth quarter of 2014 and 1.41% for the first quarter of 2014.

Total interest and dividend income for the first quarter of 2015 decreased $61.6 million, or 19.7%, to $250.9 million from $312.5 million for the first quarter of 2014. The decrease in total interest and dividend income was due to a $1.98 billion decrease in the average balance of total interest-earning assets during the first quarter of 2015 to $35.52 billion from $37.50 billion for the first quarter of 2014 as well as a decrease in the annualized weighted-average yield on total interest earning assets. The decrease in the average balance of total interest-earning assets for the first quarter of 2015 as compared to the first quarter of 2014 was due primarily to repayments and sales of mortgage-related assets as a result of the low interest rate environment and our decision not to reinvest in low yielding, long term assets. The annualized weighted-average yield on total interest-earning assets was 2.83% for the first quarter of 2015 as compared to 3.33% for the first quarter of 2014. The decrease in the annualized weighted-average yield of interest-earning assets was due to continued low market interest rates earned on mortgage-related assets and a $3.55 billion increase in investment securities with an annualized weighted-average yield of 0.41% and an increase of $1.51 billion in the average balance of Federal funds sold and other overnight deposits with an average yield of 0.25% for the quarter ended March 31, 2015.

Interest on first mortgage loans decreased $35.8 million, or 14.1%, to $217.3 million for the first quarter of 2015 from $253.1 million for the first quarter of 2014. The decrease in interest on first mortgage loans was primarily due to a $2.66 billion decrease in the average balance of first mortgage loans to $20.88 billion for the first quarter of 2015 from $23.54 billion for the first quarter in 2014. The decrease in interest on first mortgage loans was also due to a 14 basis point decrease in the annualized weighted-average yield to 4.16% for the first quarter of 2015 from 4.30% for the first quarter of 2014.

The decrease in the average yield earned on first mortgage loans during the first quarter of 2015 was due primarily to repayments of higher-yielding loans coupled with lower yields on new loan originations. Consequently, the average yield on our loan portfolio continued to decline during the first quarter of 2015.

Interest on mortgage-backed securities decreased $28.6 million to $20.1 million for the first quarter of 2015 from $48.7 million for the first quarter of 2014. This decrease was due primarily to a $4.34 billion decrease in the average balance of mortgage-backed securities to $4.09 billion for the first quarter of 2015 from $8.43 billion for the first quarter of 2014.

The decrease in the average balance of mortgage-backed securities during the first quarter of 2015 was due to sales of mortgage-backed securities and principal repayments. During 2014, we sold $3.31 billion of mortgage-backed securities to realize gains that otherwise would have decreased as repayments reduced the outstanding principal balance on these securities. During the first quarter of 2015, we sold $218.6 million of mortgage-backed securities. The decrease in interest on mortgage-backed securities was also due to a decrease of 34 basis points in the annualized weighted-average yield of mortgage-backed securities to 1.97% for the first quarter of 2015 as compared to 2.31% for first quarter of 2014.

Interest on investment securities increased $2.6 million to $4.0 million for the first quarter of 2015 as compared to $1.4 million for the first quarter of 2014. This increase was due primarily to a $3.55 billion increase in the average balance of investment securities to $3.89 billion for the first quarter of 2015 from $344.4 million for the first quarter of 2014.

Page 5

The increase in the average balance was due primarily to the purchase of $3.30 billion of U.S. Treasury securities in 2014. In addition, we purchased $800.8 million of U.S. Treasury securities during the first quarter of 2015. This increase was partially offset by a decrease in the annualized weighted-average yield to 0.41% for the first quarter of 2015 from 1.60% for the first quarter of 2014. The decrease in the annualized weighted-average yield earned on investment securities during this same period is due to the average yield earned on the U.S. Treasury securities which was 0.28%.

Interest on Federal funds sold and other overnight deposits amounted to $3.8 million for the first quarter of 2015 as compared to $2.9 million for the first quarter of 2014. The increase in interest income on Federal funds sold and other overnight deposits was due to an increase in the average balance of Federal funds sold and other overnight deposits. The average balance of Federal funds sold and other overnight deposits amounted to $6.14 billion for the first quarter of 2015 as compared to $4.63 billion for the first quarter of 2014. The increase in the average balance was due primarily to repayments and sales of mortgage-related assets and our low appetite for adding long-term fixed-rate mortgage loans to our portfolio in the current low interest rate environment. The yield earned on Federal funds sold and other overnight deposits was 0.25% for the first quarters of both 2015 and 2014.

Total interest expense for the quarter ended March 31, 2015 decreased $4.9 million, or 2.7%, to $175.3 million from $180.2 million for the quarter ended March 31, 2014. This decrease was primarily due to a $2.13 billion decrease in the average balance of total interest-bearing liabilities to $30.63 billion for the quarter ended March 31, 2015 from $32.76 billion for the quarter ended March 31, 2014. This was partially offset by an increase in the annualized weighted-average cost of total interest-bearing liabilities to 2.30% for the quarter ended March 31, 2015 as compared to 2.21% for the quarter ended March 31, 2014. The decrease in the average balance of total interest-bearing liabilities was due entirely to a decrease in the average balance of total deposits.

The increase in the average cost of interest-bearing liabilities during the first quarter of 2015 was due to a decrease in the average balance of interest-bearing deposits, which have a lower weighted-average cost than our borrowed funds, the average balances of which remained unchanged. Interest-bearing deposits accounted for 60% of interest-bearing liabilities for the quarter ended March 31, 2015 as compared to 63% for the quarter ended March 31, 2014.

Interest expense on deposits decreased $5.1 million, or 12.6%, to $35.5 million for the first quarter of 2015 from $40.6 million for the first quarter of 2014. The decrease is primarily due to a $2.14 billion decrease in the average balance of interest-bearing deposits to $18.45 billion for the first quarter of 2015 from $20.59 billion for the first quarter of 2014. The decrease is also due to a decrease in the average cost of interest-bearing deposits of 2 basis points to 0.78% for the first quarter of 2015 from 0.80% for the first quarter of 2014. The decrease in the average cost of deposits for the first quarter of 2015 reflected the low market interest rates and our decision to maintain lower deposit rates to continue our balance sheet reduction.

Interest expense on borrowed funds amounted to $139.8 million for the first quarter of 2015 as compared to $139.6 million for the first quarter of 2014. The average cost of borrowed funds was 4.59% for both the quarters ended March 31, 2015 and 2014. The average balance of borrowings was unchanged for both comparative periods. There is one borrowing scheduled to mature in the fourth quarter of 2015 for $75.0 million with an average cost of 4.62%.

Page 6

There was no provision for loan losses for the first quarters of both 2015 and 2014. No provision was needed due to improving home prices and economic conditions, a continued decrease in total delinquent loans and a continued decrease in the size of the loan portfolio.

Non-performing loans, defined as non-accruing loans and accruing loans delinquent 90 days or more, amounted to $844.6 million at March 31, 2015 as compared to $852.0 million at December 31, 2014 and $1.03 billion at March 31, 2014. The ratio of non-performing loans to total loans was 4.06% at March 31, 2015 as compared to 3.95% at December 31, 2014 and 4.32% at March 31, 2014. Notwithstanding the decrease in non-performing loans, the ratio of non-performing loans to total loans increased during the first quarter of 2015 as total loans decreased. The foreclosure process and the time to complete a foreclosure continue to be prolonged, especially in New York and New Jersey where approximately 79.0% of our non-performing loans are located. This protracted foreclosure process delays our ability to resolve non-performing loans through the sale of the underlying collateral and our ability to maximize any recoveries.

Loans delinquent 30 to 59 days amounted to $223.7 million at March 31, 2015 as compared to $278.5 million at December 31, 2014 and $276.0 million at March 31, 2014. Loans delinquent 60 to 89 days amounted to $111.4 million at March 31, 2015 as compared to $129.1 million at December 31, 2014 and $157.1 million at March 31, 2014.

The allowance for loan losses amounted to $230.5 million at March 31, 2015 as compared to $235.3 million at December 31, 2014 and $265.7 million at March 31, 2014. The allowance for loan losses as a percent of total loans and as a percent of non-performing loans was 1.11% and 27.29%, respectively, at March 31, 2015, as compared to 1.09% and 27.62%, respectively, at December 31, 2014 and 1.12% and 25.88%, respectively, at March 31, 2014.

Net charge-offs amounted to $4.8 million for the first quarter of 2015 as compared to $10.4 million for the first quarter of 2014 and $6.9 million for the linked fourth quarter of 2014. The ratio of net charge-offs to average loans was 0.09% for the first quarter of 2015 as compared to 0.18% for the first quarter of 2014 and 0.13% for the linked fourth quarter of 2014.

Total non-interest income was $8.7 million for the first quarter of 2015 as compared to $47.5 million for the linked fourth quarter of 2014 and $17.8 million for the first quarter of 2014. Included in non-interest income for the first quarter of 2015 were $7.3 million in gains from the sale of $218.6 million of mortgage-backed securities. Gains on the sales of securities amounted to $45.9 million for the linked fourth quarter of 2014 and $15.9 million in the first quarter of 2014. Sales of securities in the first quarter of 2015 were significantly reduced as we planned for a targeted Merger closing. The remainder of non-interest income is primarily made up of service fees and charges on deposit and loan accounts.

Total non-interest expense decreased $4.9 million to $74.8 million for the first quarter of 2015 as compared to $79.7 million for the first quarter of 2014. This decrease was due primarily to a $3.0 million decrease in the FDIC assessment and a $2.7 million decrease in other non-interest expense. These decreases were partially offset by an $820,000 increase in compensation and employee benefit costs.

Compensation and employee benefit costs increased $820,000, or 2.4%, to $34.4 million for the first quarter of 2015 as compared to $33.6 million for the same period in 2014. The increase in compensation and employee benefit costs is comprised of a $1.6 million increase in postretirement benefit costs partially offset by decreases in medical plan expenses of $440,000 and $224,000 in compensation expense. At March 31, 2015, we had 1,498 full-time equivalent employees as compared to 1,507 at December 31, 2014.

For the three months ended March 31, 2015, Federal deposit insurance expense decreased $3.0 million, or 21.6%, to $10.9 million compared to $13.9 for the same period in 2014. This decrease was due primarily to a reduction in the size of our balance sheet and a decrease in our assessment rate.

Other non-interest expense decreased $2.7 million to $19.8 million for the quarter ended March 31, 2015 as compared to $22.5 million for the first quarter of 2014. This decrease was due primarily to a $3.0 million write-down in the receivable related to the Lehman Brothers, Inc. liquidation taken during the first quarter of 2014, partially offset by an increase of $501,000 in foreclosed real estate expenses.

Included in other non-interest expense were net gains of $348,000 resulting from foreclosed real estate transactions for the first quarter of 2015 as compared to a net gain of $78,000 for the same period in 2014. We sold 49 properties during the first quarter of 2015 as compared to 46 properties for the same period in 2014. Expenses associated with foreclosed real estate were $4.7 million and $4.2 million for the three months ended March 31, 2015 and 2014, respectively.

Our operating efficiency ratio was 87.97% for the 2015 first quarter as compared to 51.11% for the 2014 first quarter. The calculation of the operating efficiency ratio is included in a table contained in this press release. Our return on average assets was 0.06% for the 2015 first quarter as compared to 0.44% for the 2014 first quarter. Our annualized ratio of non-interest expense to average total assets for the first quarter of 2015 was 0.82% as compared to 0.83% for the first quarter of 2014.

Income tax expense amounted to $3.7 million for the first quarter of 2015 as compared to income tax expense of $27.9 million for the corresponding period in 2014. Our effective tax rate for the first quarter of 2015 was 38.71% compared with 39.58% for the first quarter of 2014.
