SeaWorld Entertainment, Inc. Reports First Quarter 2015 Results

ORLANDO, Fla., May 7, 2015— SeaWorld Entertainment, Inc. (NYSE: SEAS), a leading theme park and entertainment company, today reported financial results for the quarter ended March 31, 2015.

Overview

“The timing of Easter, our consumer event programs, strong passholder visitation and increased promotional offerings helped drive attendance growth in the first quarter,” said Joel Manby, President and Chief Executive Officer of SeaWorld Entertainment, Inc. “Looking ahead to the remainder of the year, we remain cautious as the first quarter accounts for a relatively small portion of full year attendance, competitive pressures remain in Orlando and our marketing and reputation campaigns are still in their early stages.”

First Quarter 2015 Results

For the first quarter of 2015, the Company generated revenue of $214.6 million, an increase of $2.3 million, or 1%, versus the first quarter of 2014. Adjusted EBITDA was a loss of $3.8 million compared to a loss of $15.0 million in the first quarter of 2014. The Company reported a net loss of $43.6 million, or a loss of $0.51 per diluted share, in the first quarter of 2015. In the first quarter of 2014, the Company generated a net loss of $49.2 million, or a loss of $0.56 per diluted share. Net cash provided by operating activities was $37.7 million in the first quarter of 2015 compared to $13.0 million in the prior year first quarter. Free Cash Flow was a deficit of $3.0 million for the first quarter of 2015 compared to a deficit of $33.8 million in the first quarter of 2014.

The increase in revenue was driven by a 5.6% increase in attendance, offset by a total revenue per capita decrease of 4.2% to $66.77 from $69.72 in the first quarter of 2014. Admission per capita, defined as admissions revenue divided by total attendance, decreased by 5.6% to $42.58 in the first quarter of 2015 from $45.12 in the prior year first quarter primarily as a result of an increase in promotional offerings and passholder visitation along with park attendance mix impacts. In-park per capita spending, calculated as food, merchandise and other revenue divided by total attendance, decreased by 1.7% to $24.19 in the first quarter of 2015 compared to $24.60 in the prior year first quarter primarily due to strong passholder visitation for the quarter.

Attendance in the first quarter of 2015 increased due to the impact of an earlier Easter holiday and an overall improvement in demand. The earlier Easter timing caused a shift in the spring break holiday period for some schools in the Company’s key source markets, while the overall improvement in demand was driven by the Company’s consumer event programs, strong passholder visitation and increased promotional offerings.

Other

On March 3, 2015, the Company’s Board of Directors declared a cash dividend of $0.21 per share, which was paid on April 1, 2015, to all common stockholders of record at the close of business on March 13, 2015.

On March 30, 2015, the Company’s wholly-owned subsidiary, SeaWorld Parks and Entertainment, Inc. (“SEA”), entered into an incremental term loan amendment, Amendment No. 7 (the “Incremental Amendment”) to its existing Senior Secured Credit Facilities. On April 7, 2015, SEA borrowed $280 million of additional term loans (the “Term B-3 Loans”) pursuant to the Incremental Amendment. The proceeds of the Term B-3 Loans, along with cash on hand, were used to (i) redeem all $260 million of the outstanding principal amount of SEA’s 11.0% Senior Notes due 2016 (the “Redeemed Notes”) at a redemption price of 105.5% plus accrued and unpaid interest on the Redeemed Notes and (ii) pay transaction fees and other expenses in connection with the Term B-3 Loans.

Statement Regarding Non-GAAP Financial Measures

This earnings release and accompanying financial statement tables include several supplemental non-GAAP financial measures, including Adjusted EBITDA, Adjusted Net (Loss) Income, Adjusted Net (Loss) Income per Diluted Share and Free Cash Flow. Adjusted EBITDA, Adjusted Net (Loss) Income, Adjusted Net (Loss) Income per Diluted Share and Free Cash Flow are not recognized terms under GAAP, should not be considered in isolation or as a substitute for a measure of liquidity or performance prepared in accordance with GAAP and are not indicative of net income or loss or net cash provided by operating activities as determined under GAAP. Adjusted EBITDA, Adjusted Net (Loss) Income, Adjusted Net (Loss) Income per Diluted Share, Free Cash Flow and other non-GAAP financial measures have limitations that should be considered before using these measures to evaluate the Company’s liquidity or financial performance. Adjusted EBITDA, Adjusted Net (Loss) Income, Adjusted Net (Loss) Income per Diluted Share and Free Cash Flow, as presented, may not be comparable to similarly titled measures of other companies due to varying methods of calculation.

Adjusted EBITDA is defined as net (loss) income before income tax expense, interest expense, depreciation and amortization, as further adjusted to exclude certain non-cash, and other items permitted in calculating covenant compliance under the credit agreement governing the Company’s senior secured credit facilities. Adjusted EBITDA is a material component of these covenants. Management presents Adjusted EBITDA because it believes that it provides additional information to investors about the calculation of and compliance with these financial covenants. Management also uses Adjusted EBITDA in connection with certain components of its executive compensation program. In addition, investors, lenders, financial analysts and rating agencies have historically used EBITDA-related measures in the Company’s industry, along with other measures to evaluate a company’s ability to meet its debt service requirement, to estimate the value of a company and to make informed investment decisions.

Adjusted Net (Loss) Income is defined as net (loss) income before the after-tax impact of the restructuring and other related costs, the secondary offering costs, and the loss on early extinguishment of debt and write-off of discounts and deferred financing costs, if any, during the periods presented. Adjusted Net (Loss) Income per Diluted Share is calculated by dividing Adjusted Net (Loss) Income for the period by the diluted shares outstanding. Management presents Adjusted Net (Loss) Income and Adjusted Net (Loss) Income per Diluted Share to eliminate the impact of items, net of tax, that management does not consider indicative of ongoing operating performance due to their inherent unusual nature or because they result from an event of a similar nature.

Free Cash Flow is defined as net cash provided by operating activities reduced by capital expenditures. Management presents Free Cash Flow because it believes it provides supplemental information to assist investors in analyzing the Company’s ability to generate liquidity from its operating activities. Free Cash Flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures as it does not take into consideration certain other non-discretionary cash requirements, such as mandatory principal payments on the Company’s long-term debt.

The financial statement tables that accompany this press release include a reconciliation of non-GAAP financial measures to the applicable most comparable U.S. GAAP financial measures.
