SINCLAIR REPORTS $0.19 DILUTED EARNINGS PER SHARE IN FIRST QUARTER 2011; DECLARES $0.12 QUARTERLY DIVIDEND PER SHARE

BALTIMORE (May 4, 2011) — Sinclair Broadcast Group, Inc. (Nasdaq: SBGI), the “Company” or “Sinclair,” today reported financial results for the three months ended March 31, 2011.

“We continue to see growth in our core business, both in the first quarter and in our second quarter expectations,” commented David Smith, President and CEO of Sinclair.  “We are also seeing continued advertising growth in the auto category, although our outlook provides for some slowing due to new car production disruptions as a result of the Japanese crisis.  We believe that once the auto parts and supply issues are addressed, manufacturers and dealers will increase their advertising in order to announce restocked inventories and to compete for their share of any pent up consumer demand.”

Mr. Smith continued, “Our Board of Directors once again declared a quarterly cash dividend in the amount of $0.12 per share payable June 15, 2011.  In March, we amended our Bank Credit Agreement to allow for increased flexibility in using our cash flow.  As such, we continue to evaluate available options to build the Company and enhance shareholder returns.”

Financial Results:

Net broadcast revenues from continuing operations were $155.9 million for the three months ended March 31, 2011, an increase of 5.4% versus the prior year period result of $147.9 million.  The Company had operating income of $50.5 million in the three-month period, as compared to operating income of $45.6 million in the prior year period.  The Company had net income attributable to Sinclair of $15.3 million in the three-month period versus net income of $11.5 million in the prior year period.

The Company reported diluted earnings per common share of $0.19 for the three-month period versus diluted earnings per common share of $0.14 in the prior year period.

Operating Statistics and Income Statement Highlights:

·Political revenues were $0.6 million in the first quarter 2011 versus $1.5 million in first quarter 2010.

·Revenues related to the February 6, 2011 Super Bowl, which aired on our 20 FOX affiliates, were $6.2 million.  This represented a 26.5% increase over the $4.9 million we generated in 2008, the last time the FOX Network aired the Super Bowl.

·Local net broadcast revenues, which include local time sales, retransmission revenues, and other broadcast revenues, were up 7.6% in the first quarter 2011, in part due to the Super Bowl revenues; while national net broadcast revenues, which include national time sales and other national broadcast revenues, were down 1.4% versus the first quarter 2010 due to the absence of political.  Excluding political revenues, local net broadcast revenues were up 7.6% and national net broadcast revenues were up 1.2% in the first quarter.

·Advertising categories that reported the largest spending increases in the first quarter were automotive, schools, pharmaceuticals, and furniture, while restaurants, home products, grocery, paid programming and religious programming were down the most.  Automotive, our largest category, was up 22.7% in the quarter.

·The Company entered into multi-year retransmission consent agreements with Comcast Corporation and Cox Communications.

Balance Sheet and Cash Flow Highlights:

·Debt on the balance sheet, net of $123.4 million in cash, was $1,133.4 million at March 31, 2011 versus net debt of $1,164.2 million at December 31, 2010 and net debt of $1,263.7 million at December 31, 2009.  Included in the cash and debt balances is $70.0 million related to the redemption of the 6% debentures due 2012 (the “6% notes”) which were called March 16, 2011 and redeemed in full on April 15, 2011.

·On March 15, 2011, the Company paid a $0.12 per share quarterly cash dividend to its shareholders.

·On January 18, 2011, the put period for the holders of the remaining $5.7 million of outstanding 4.875% convertible senior notes due 2018, allowing the holders to put their notes to the Company at par value, expired without any holders exercising their put rights.  As a result, the remaining $5.1 million of cash held in an escrow account was released to the Company and subsequently used to prepay a portion of its Term B Loan.

·As of March 31, 2011, 52.0 million Class A common shares and 28.9 million Class B common shares were outstanding, for a total of 80.9 million common shares outstanding.

·Capital expenditures in the first quarter were $6.1 million.

“We remain confident in the strength of our core business for the full year 2011,” commented David Amy, EVP and CFO.  “Our cautious net broadcast revenue guidance for the second quarter reflects factors beyond our control, including the Japanese crisis and political upheaval in the Middle East and northern Africa, which are creating supply chain issues and accelerated oil prices.”

·The Company expects second quarter 2011 station net broadcast revenues from continuing operations, before barter, to be approximately $159.2 million to $161.2 million, an increase of 0.3% to 1.6% as compared to second quarter 2010 station net broadcast revenues of $158.7 million.  This assumes approximately $0.9 million in political revenues in the second quarter as compared to $3.8 million in second quarter 2010.  Excluding political, net broadcast revenues are expected to be up 2.2% to 3.5% in the quarter.

·The Company expects barter revenue to be approximately $17.4 million in the second quarter.

·The Company expects barter expense to be approximately $17.4 million in the second quarter.

·The Company expects continuing operations station production expenses and station selling, general and administrative expenses (together, “television expenses”), before barter expense, in the second quarter to be approximately $72.8 million, a 5.0% increase from second quarter 2010 television expenses of $69.3 million.  On a full year basis, television expenses are expected to be approximately $295.9 million, up 5.2% as compared to 2010 television expenses of $281.3 million.  The 2011

expense forecast includes $1.3 million of stock-based compensation expense for the year as compared to $1.7 million for 2010.

·The Company expects program contract amortization expense to be approximately $13.6 million in the second quarter and $55.1 million for 2011, as compared to the 2010 actuals of $15.3 million and $60.9 million for the quarter and year, respectively.

·The Company expects program contract payments to be approximately $18.1 million in the second quarter and $68.3 million for 2011, as compared to the 2010 actuals of $21.4 million and $89.0 million for the quarter and year, respectively.

·The Company expects corporate overhead to be approximately $7.5 million in the second quarter and $30.4 million for 2011, as compared to the 2010 actuals of $7.3 million and $26.8 million for the quarter and year, respectively.  The 2011 corporate expense forecast includes $0.6 million of stock-based compensation expense for the quarter and $3.7 million for the year, as compared to the 2010 actuals of $0.4 million and $2.5 million for the quarter and year, respectively.

·The Company expects other operating division revenues less other operating division expenses to be $1.0 million of income in the second quarter and $3.8 million of income for 2011, as compared to the 2010 actuals of $0.1 million of income in the quarter and $0.7 million of income for the year.  This assumes current equity interests and excludes a portion of income for Alarm Funding, which we intend to divest and which has been classified as discontinued operations pursuant to accounting guidance.

·The Company expects discontinued operations income, net of taxes, to be $0.4 million for the second quarter and $1.8 million for 2011, as compared to the 2010 actuals of $0.3 million and $0.7 million for the quarter and year, respectively.

·The Company expects depreciation on property and equipment to be approximately $8.4 million in the second quarter and $32.6 million for 2011, assuming the capital expenditure assumptions below, and as compared to the 2010 actuals of $9.1 million and $36.3 million for the quarter and year, respectively.

·The Company expects amortization of acquired intangibles to be approximately $3.9 million in the second quarter and $15.4 million for 2011, as compared to the 2010 actuals of $4.2 million and $16.7 million for the quarter and year, respectively.

·The Company expects net interest expense to be approximately $24.3 million in the second quarter and $100.6 million for 2011 (approximately $91.4 million on a cash basis), assuming no changes in the current interest rate yield curve, the redemption of the 6% notes in April 2011, and changes in debt levels based on the assumptions discussed in this “Outlook” section.  This compares to the 2010 actuals of $28.1 million and $114.9 million ($103.9 million on a cash basis) for the second quarter and year, respectively.

assumptions discussed in this “Outlook” section.  The Company expects the effective tax rate to be approximately 37.4% for the second quarter and full year, respectively.

·The Company expects to spend approximately $18.8 million in capital expenditures in the second quarter and approximately $36.5 million for the year in order to take advantage of the bonus depreciation tax deduction rules.  Of the second quarter amount, approximately $9.1 million relates to master control upgrades.
