Item 2.02. Results of Operations and Financial Condition

Preliminary First Quarter 2015 Results

The financial results for Tribune Media Company (“we” or the “Company”) for the first quarter of 2015 are not yet finalized. However, the following information reflects management’s current expectations with respect to the Company’s first quarter 2015 results.

Operating Revenues

We expect consolidated operating revenues for the three months ended March 29, 2015 to be approximately $472 million, an increase of $26 million, or 6%, as compared to the three months ended March 30, 2014.

Television and Entertainment segment revenues are expected to be approximately $410 million for the three months ended March 29, 2015, an increase of $10 million, or 2%, as compared to the three months ended March 30, 2014. This increase was primarily due to an expected increase in retransmission consent revenues and carriage fees of approximately $21 million, partially offset by an expected decline in core advertising revenues (local and national advertising revenues, excluding political revenues) of approximately $6 million. The decline in core advertising revenues was primarily impacted by an approximate $10 million decline in revenues associated with airing the Super Bowl on two NBC-affiliated stations in 2015 as compared to 14 FOX-affiliated stations in 2014. Excluding this impact, core advertising revenues are expected to increase by 1.4% in the three months ended March 29, 2015 as compared to the three months ended March 30, 2014.

Digital and Data segment revenues are expected to be approximately $50 million for the three months ended March 29, 2015, an increase of $18 million, or 59%, as compared to the three months ended March 30, 2014. This increase is primarily attributable to the acquisition of Gracenote, which was consummated January 31, 2014, and the acquisitions of HWW, Baseline and What’s ON, which were consummated in the second half of 2014.

Real estate revenues within Corporate and Other are expected to be approximately $12 million for the three months ended March 29, 2015, a decrease of approximately $2 million as compared to the three months ended March 30, 2014.

Adjusted EBITDA

We expect consolidated Adjusted EBITDA for the three months ended March 29, 2015 to be approximately $129 million, a decrease of approximately $9 million, or 6.5%, compared to the three months ended March 30, 2014.

Television and Entertainment Adjusted EBITDA is expected to be approximately $135 million for the three months ended March 29, 2015, a decrease of $5 million, or 3%, as compared to the three months ended March 30, 2014. This decrease is primarily attributable to higher programming costs including original and syndicated content.

Digital and Data Adjusted EBITDA is expected to be approximately $12 million for the three months ended March 29, 2015, an increase of approximately $7 million as compared to the three months ended March 30, 2014. This increase is primarily attributable to the operating impact of the acquisitions of Gracenote, HWW, Baseline and What’s ON in 2014.

Corporate and Other Adjusted EBITDA is an expected loss of approximately $18 million for the three months ended March 29, 2015, compared to a loss of $7 million for the three months ended March 30, 2014. These additional losses were a result of increased expenses primarily attributable to higher corporate costs driven by increased compensation expense and costs associated with the implementation of improved business and technology applications.

Cautionary Statement Regarding Preliminary Results for the First Quarter of 2015

The estimated first quarter of 2015 results are preliminary, unaudited and subject to completion, reflect management’s current views and may change as a result of management’s review of results and other factors, including a wide variety of significant business, economic and competitive risks and uncertainties. Such preliminary results are subject to the closing of the first quarter of 2015 and finalization of first quarter financial and accounting procedures (which have yet to be performed) and should not be viewed as a substitute for full quarterly financial statements prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). We caution you that the first quarter 2015 estimates are not guarantees of future performance or outcomes and that actual results may differ materially from those described above. Factors that could cause actual results to differ from those described above are set forth in the Company’s filings with the Securities and Exchange Commission (the “SEC”) and under “—Cautionary Statement Regarding Forward-Looking Statements” below. You should read this information together with the financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for prior periods included in the Company’s SEC filings. Neither our independent registered public accounting firm nor any other independent registered public accounting firm has audited, reviewed or compiled, examined or performed any procedures with respect to the preliminary results, nor have they expressed any opinion or any other form of assurance on the preliminary results.

Adjusted EBITDA Description and Reconciliations

Adjusted EBITDA is a financial measure that is not required by, or presented in accordance with, GAAP. We believe that Adjusted EBITDA is a measure commonly used by investors to evaluate our performance and that of our competitors. We further believe that the disclosure of Adjusted EBITDA is useful to investors, as this non-GAAP measure is used, among other measures, by our management to evaluate our performance. By disclosing Adjusted EBITDA, we believe that we create for investors a greater understanding of, and an enhanced level of transparency into, the means by which our management operates our company. Adjusted EBITDA is not a measure presented in accordance with GAAP, and our use of the term Adjusted EBITDA may vary from that of others in our industry. Adjusted EBITDA has limitations as an analytical tool and should not be considered as an alternative to net income, operating profit, revenues or any other performance measures derived in accordance with GAAP as measures of operating performance. Some of these limitations include:

Consolidated Adjusted EBITDA

Consolidated Adjusted EBITDA is defined as net income before income (loss) from discontinued operations, net of taxes, income taxes, interest income, interest expense, pension expense (credit), equity income and losses, depreciation and amortization, stock-based compensation, certain special items (including severance), non-operating items and reorganization items. The following table reconciles Adjusted EBITDA to net income for the periods presented:

Operating Segments Adjusted EBITDA

Adjusted EBITDA for the Company’s operating segments is defined as segment operating profit (loss) before depreciation, amortization, pension expense (credit), stock-based compensation and certain special items (including severance).

Television and Entertainment Adjusted EBITDA

The following table reconciles Television and Entertainment Adjusted EBITDA to Television and Entertainment operating profit for the periods presented:

Full Year 2015 Outlook

In 2015, we continue to expect solid revenue growth despite it being an off-cycle political year. We anticipate that Adjusted EBITDA in 2015 will be impacted by the cyclical loss of political advertising, continued measured programming investment in WGN America and increased operational costs in our Digital and Data segment. We continue to expect the following financial results as it relates to full year 2015:

5

In our Television and Entertainment segment, programming expenses for WGN America and Tribune Studios in 2015 are currently expected to be approximately $14 million higher than the previous guidance of approximately $130 million primarily as a result of a change in the timing of the amortization of original programming expenses, which will result in a shift of expenses from 2016 into 2015. We expect that this increase in programming expense will be offset in 2015 by, among other things, an acceleration of cost savings actions.

These estimated results for full year 2015 are forward-looking statements based on management’s estimates as of the date hereof, and our actual results may be materially different from these estimated results. They are preliminary, unaudited and reflect management’s current views with respect to future results and may change as a result of industry or other developments through year-end 2015, management’s review of our actual results and other factors, including, among others, delays in the anticipated timing of activities related to our cost savings actions, unexpected costs associated with operating our business and the performance of our business. These expected financial results are based upon a number of assumptions and estimates that are in turn based on our analysis of the various factors which currently, and could in the future, impact our business. These assumptions and estimates are inherently uncertain and subject to significant business, operational, economic and competitive uncertainties and contingencies. Certain of the assumptions relate to business decisions that are subject to change, including, among others, our anticipated business strategies, our marketing strategies, our program development strategies and our ability to anticipate and react to business trends. Other assumptions relate to risks and uncertainties beyond our control, including, among others, the economic environment in which we operate, government regulation and other developments in our industry. Our actual results for the full year 2015 may differ materially from the estimates set out in this report if any of these assumptions prove incorrect. Accordingly, you should not place undue reliance on these estimated results and they should not be viewed as a substitute for our historical financial information presented in the Company’s SEC filings, including our audited consolidated financial statements and the related notes. Our independent registered public accounting firm has not audited, reviewed or performed any procedures with respect to these estimated results and does not express any opinion or any other form of assurance with respect thereto.

Reconciliations of the forecasted ranges for Adjusted EBITDA for fiscal 2015 are not included in this report due to the number of variables in the projected ranges for full year 2015 Adjusted EBITDA and because we are currently unable to quantify accurately certain amounts that would be required to be included in the GAAP measures or the individual adjustments for such reconciliations. In addition, we believe such reconciliations would imply a degree of precision that would be confusing or misleading to investors.

Cautionary Statement Regarding Forward-Looking Statements

Forward-looking statements are subject to known and unknown risks and uncertainties, many of which may be beyond our control. “Forward-looking statements” include all statements that do not relate solely to historical or current facts, and can be identified by the use of words such as “may,” “might,” “will,” “could” “should,” “estimate,” “project,” “plan,” “anticipate,” “expect,” “intend,” “outlook,” “seek,” “designed,” “assume,” “implied,” “believe” and other similar expressions.

You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates. These forward-looking statements are based on estimates and assumptions by our management that, although we believe to be reasonable, are inherently uncertain and subject to a number of risks and uncertainties. The following list represents some, but not necessarily all, of the factors that could cause actual results to differ from historical results or those anticipated or predicted by these forward-looking statements: changes in advertising demand and audience shares; competition and other economic conditions including incremental fragmentation of the media landscape and competition from other media alternatives; changes in the overall market for broadcast and cable television advertising, including through regulatory and judicial rulings; our ability to protect our intellectual property and other proprietary rights; our ability to adapt to technological changes; availability and cost of quality network,
