TOWN SPORTS INTERNATIONAL HOLDINGS, INC. ANNOUNCES SECOND QUARTER 2013 FINANCIAL RESULTS

New York, NY – July 24, 2013 – Town Sports International Holdings, Inc. (“TSI” or the “Company”) (NASDAQ: CLUB), a leading owner and operator of health clubs located primarily in major cities from Washington, DC north through New England, operating under the brand names “New York Sports Clubs,” “Boston Sports Clubs,” “Washington Sports Clubs” and “Philadelphia Sports Clubs,” announced its results for the second quarter ended June 30, 2013.

Second Quarter Overview:

Robert Giardina, Chief Executive Officer of TSI, commented: “Our overall results were broadly in line with our expectations with a sequential improvement in personal training revenues as we continue to make nice strides with our personal training membership product. We are particularly pleased to have exceeded our EBITDA expectations for the quarter and generated $15 million in free cash flow to end the quarter with a cash balance of $69.5 million. After a soft start to the year, which we believe was impacted by macro factors, our overall business is back on plan as we head into the third quarter. We are excited about the direction of our business, including an outlook for improved comparable club revenue, driven by personal training and pricing, in the back half of the year.”

Second Quarter Ended June 30, 2013 Financial Results:

Revenue (in thousands):

Total revenue for Q2 2013 decreased $2.1 million, or 1.7%, compared to Q2 2012. Revenue at clubs operated for over 12 months (“comparable club revenue”) decreased 1.7% in Q2 2013. Memberships at our comparable clubs were down 3.1% which was partially offset by a 1.4% increase in the price of our dues and fees.

The increase in joining fees revenue of 42.3% was, in part, due to the effect of the lower estimated average membership life of 24 months in effect for our unrestricted members during Q2 2013 compared to a higher estimated average membership life of 28 months in effect for Q2 2012. The lower amortizable life in the current period resulted in higher joining fees revenue recognition as joining fees were amortized over a shorter estimated average membership life.

Total operating expenses decreased $3.3 million, or 3.1%, in Q2 2013 compared to Q2 2012. Operating margin was 12.5% for Q2 2013 compared to 11.3% in Q2 2012. The total months of club operation increased 0.2% from 480 in Q2 2012 to 481 in Q2 2013. The decrease in operating expense was impacted, in part, by the receipt of $2.5 million of insurance proceeds received in connection with property damaged by Hurricane Sandy as well as the following factors:

Payroll and related. Payroll and related expenses decreased $1.3 million, or 2.8%, to $44.0 million in Q2 2013 compared to $45.3 million in Q2 2012. The decrease was due to decreases in bonuses and commissions as well as decreases in management incentive bonuses.

Club operating. Club operating expenses decreased $495,000, or 1.1%, to $44.1 million in Q2 2013 compared to $44.6 million in Q2 2012, primarily due to declines in rent and occupancy expenses and utilities, partially offset by increased repairs and maintenance expense.

General and administrative. The increase in general and administrative expenses in Q2 2013 was impacted by increases in insurance expense and increases in computer maintenance expense related to the implementation of a new club operating system.

Depreciation and amortization. Depreciation and amortization expense for Q2 2013 was relatively flat to the same period in the prior year. Modest decreases in depreciation were offset by an acceleration of depreciation of $331,000 at a single club where we have a planned near-term reduction of rental space at the location.

Net income for Q2 2013 was $6.2 million compared to net income of $5.4 million for Q2 2012.

Cash flow from operating activities for the six months ended June 30, 2013 totaled $44.5 million, an increase of $9.5 million from the corresponding period in 2012. This increase was primarily driven by increases in overall earnings, a decrease in cash paid for interest of $1.2 million and cash flows resulting from the timing of certain payments and collections made associated with our accounts receivable.

Third Quarter 2013 Financial Outlook:

Based on the current business environment, recent performance and current trends in the marketplace and subject to the risks and uncertainties inherent in forward-looking statements, our outlook for the third quarter of 2013 includes the following:

Investing Activities Outlook:

For the year ending December 31, 2013, we are lowering our capital expenditures guidance and now plan to invest $34.0 million to $37.0 million in capital expenditures. This is a reduction from our previous expectation of $37.0 million to $42.0 million. The amount includes approximately $10.0 million to $12.0 million related to potential 2013 and 2014 club openings, inclusive of amounts for our recently acquired Fitcorp chain in Boston and planned renovations at these clubs as well as the separate single club acquired in Manhattan. The total capital expenditures also includes approximately $17.0 million to $18.0 million to continue enhancing or upgrading existing clubs and approximately $4.5 million to $5.0 million principally related to major renovations at clubs with recent lease renewals and to upgrade our in-club entertainment system network. We also expect to invest approximately $2.5 million to $3.0 million to enhance our management information and communication systems. We expect these capital expenditures to be funded by cash flow provided by operations and available cash on hand.

Non-GAAP Financial Measures – EBITDA and Adjusted EBITDA

EBITDA consists of net income plus interest expense (net of interest income), provision for corporate income taxes, and depreciation and amortization. Adjusted EBITDA is the Company’s EBITDA excluding loss on extinguishment of debt, any fixed asset or goodwill impairments, insurance recoveries and, in the case of Q4 2012 and full year-2012, charges in connection with the Company’s special dividend payment and incremental share-based compensation expense resulting from option modifications. EBITDA is not a measure of liquidity or financial performance presented in accordance with GAAP. EBITDA, as we define it, may not be identical to similarly titled measures used by some other companies.

EBITDA has material limitations as an analytical tool and should not be considered in isolation or as a substitute for cash flows from operating activities, operating income or other cash flow or income data prepared in accordance with GAAP. The items excluded from EBITDA, but included in the calculation of reported net income, are significant components of the consolidated statements of cash flows and income, and must be considered in performing a comprehensive assessment of our liquidity.

EBITDA excludes, among other items, the effect of depreciation and amortization, which is a significant component of our reported GAAP data. Depreciation and amortization, which is a non-cash item, totaled $12.4 million in the quarter ended June 30, 2013. Although a premise underlying depreciation and amortization is that it will be reinvested in our business to restore, replenish or purchase property, equipment and other related assets, the funds represented by depreciation and amortization could, in the Company’s discretion, be utilized for other purposes (e.g., debt service). Accordingly, EBITDA may be useful as a supplemental measure to GAAP financial data for demonstrating our ability to satisfy our liquidity and capital resource requirements.

Investors or prospective investors in the Company regularly request EBITDA as a supplemental analytical measure to, and in conjunction with, our GAAP financial data. We understand that these investors use EBITDA, among other things, to assess our ability to service our existing debt and to incur debt in the future, to evaluate our executive compensation programs, to assess our ability to fund our capital expenditure program, and to gain insight into the manner in which the Company’s management and board of directors analyze our liquidity. We believe that investors find the inclusion of EBITDA in our press releases to be useful and helpful to them.

Our management and board of directors also use EBITDA as a supplemental measure to our GAAP financial data for purposes broadly similar to those used by investors.

The purposes to which EBITDA may be used by investors, and is used by our management and board of directors, include the following:

Adjusted EBITDA has similar uses and limitations as EBITDA. We do not, and investors should not, place undue reliance on EBITDA or Adjusted EBITDA as a measure of our liquidity.
