BEIJING — August 26, 2015 — Bona Film Group Limited (NASDAQ: BONA) (“Bona” or the “Company”), a leading film distributor and vertically integrated film company in China, today announced unaudited financial results for the second quarter ended June 30, 2015.

“Our continued revenue growth in the second quarter of 2015 reflects the strength of our unique, vertically integrated business model,” said Bona’s founder, Chairman and CEO Mr. Yu Dong (“Mr. Yu”).  “We distributed five films in the second quarter and achieved 58.5% year-over-year revenue growth overall, with 72.9% year-over-year growth in our film distribution segment, as the film SPL2 had a strong box office performance. Revenue in our movie theater segment increased 50% year-over-year, benefitting from the opening of four state-of-the-art theaters in the first quarter of 2015, as well as from the ongoing rapid expansion of China’s movie industry. I am very excited about our film slate for the second half of the year, which includes such highly anticipated productions as Bride Wars, The Treasure, The Dead End, and The Cinema That Never Dies, formerly titled The Phantom of Shanghai. Finally, we are seeing great progress in our cooperation initiatives with US film producers. I am pleased to report that the film we are developing in partnership with Tristar and Studio 8, Billy Lynn’s Long Halftime Walk, successfully completed principal photography in July, has moved into the post-production phase, and is expected to be released in November 2016.”

Second Quarter 2015 Financial Results

Net Revenues

	2Q15	2Q14	Y-o-Y%
Net Revenues (US$mm)	71.1	44.9	58.5	%

Net revenues for the second quarter of 2015 increased 58.5% year-over-year to US$71.1 million. The increase in net revenues was primarily attributable to an increase in net revenues from the film distribution segment and an increase in net revenues from the Company’s movie theater segment. These increases are a result of the increase in the number of theaters and screens from our strategic expansion efforts in the theater segment and the maturation of theaters over time.

Net Revenues from External Customers (US$mm)	43.0	—	28.0	0.1	—		71.1

During the second quarter of 2015, Bona distributed and/or invested in a total of five films, with SPL2 being well received by movie audiences.

Net revenues from the film investment and production segment were US$20.4 million in the second quarter of 2015, an increase of 33.3% from US$15.3 million in the second quarter of 2014. The increase was mainly derived from Bona’s investments in films released in the second quarter of 2015, in particular the successful film SPL2.

Net revenues from the movie theater segment were US$29.1 million in the second quarter of 2015, a 50.0% increase from US$19.4 million in the second quarter of 2014. The increase was mainly due to the increase in the number of theaters and screens from the Company’s strategic expansion efforts, and the maturation of new theaters over time.

For the second quarter of 2015, gross profit increased 44.4% to US$33.9 million from US$23.5 million in the second quarter of 2014. The year-over-year increase in gross profit was primarily attributable to strong performance from the Company’s film distribution segment.

Margin for the Company’s film investment and production segment was negative 2.5% in the second quarter of 2015, compared with a segment margin of 5.0% in the second quarter of 2014. The decrease in this segment’s margin was mainly due to poor performance of certain films invested and released in the second quarter of 2015.

Margin for the Company’s movie theater segment was 57.7% in the second quarter of 2015, compared with 59.2% in the second quarter of 2014.

The year-over-year increase in operating expenses was primarily due to an increase in film participation expenses and selling and marketing expenses for the promotion and advertising of the Company’s distributed films in the second quarter of 2015, as well as an increase in general and administrative expenses due to the expansion of the movie theater segment and the increase in the share-based compensation expenses.

Operating margin in the second quarter of 2015 was 4.0% compared with 2.3% in the second quarter of 2014. The year-over-year increase in operating margin was primarily due to the growth in the Company’s film distribution and movie theater businesses.

Cash and Cash Flow

As of June 30, 2015, Bona had cash and cash equivalents and restricted cash totaling US$158.9 million, compared with US$153.6 million as of December 31, 2014. Net cash provided by operating activities for the second quarter of 2015 was US$51.2 million, compared with net cash used in operating activities of US$32.8 million for the second quarter of 2014. The change in cash flow from operations was mainly attributable to the accelerated collection of the accounts receivables from film distribution.

Business Outlook

Based on current market and operating conditions, the Company expects non-GAAP net income for the third quarter of 2015 to be in the range of US$4.5 million to US$5 million. These estimates do not include any potential costs that may be incurred by the Company in connection with the preliminary proposal by Mr. Yu, Sequoia Capital China I LP and Fosun International Limited (collectively, the “Buyer Group”) to acquire all of the Company’s outstanding shares, which is further described below.

“While the Chinese film industry is expected to maintain strong growth throughout 2015, I believe Bona can outpace the industry by executing on our integrated business model. Our upcoming film slate, new top quality theaters, industry leading marketing technology, and exciting international initiatives provide a foundation for sustained success.  We will continue to invest for growth, as we build Bona into a leading international entertainment company,” concluded Mr. Yu.

Preliminary Proposal to Acquire All Outstanding Shares of the Company

The Company received a preliminary non-binding proposal letter, dated June 12, 2015, from the Buyer Group, to acquire all of the Company’s outstanding shares at $13.70 per ADS, or approximately $27.40 per ordinary share.  The board of directors of the Company has formed a committee of independent directors to review and evaluate this proposal.  The Company cautions its shareholders and others considering trading its securities that neither the board of directors nor the independent committee has made any decision with respect to the Company’s response to the proposal by the Buyer Group. There can be no assurance that any definitive offer will be made, that any agreement will be executed or that this or any other transaction will be approved or consummated. The Company does not undertake any obligation to provide any updates with respect to this proposal or any other transaction, except as required under applicable law.

Non-GAAP Financial Measures

To supplement Bona’s consolidated financial results presented in accordance with GAAP, Bona uses the following measures defined as non-GAAP financial measures by the SEC: non-GAAP net income, non-GAAP net income attributable to Bona Film Group Limited per ADS, which exclude share-based compensation expenses, and adjusted EBITDA, non-GAAP, which excludes share-based compensation expenses, interest, taxes, and non-cash depreciation and amortization charges. The presentation of these non-GAAP financial measures is not intended to be considered in isolation, as a substitute for, or to be superior to the financial information prepared and presented in accordance with GAAP. In addition, Bona’s definition of non-GAAP net income may be different from the definitions used by other companies, and therefore comparability may be limited.

Bona believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding certain expenses and expenditures that may not be indicative of its operating performance and a supplemental liquidity measure which is useful for understanding and evaluating the Company’s capacity for servicing its debt, and otherwise meeting its cash needs. Adjusted EBITDA, non-GAAP excludes depreciation and amortization, so it does not reflect any cash requirements for the replacement of the assets, which will often have to be replaced in the future. The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing the Company’s performance and liquidity, and when planning and forecasting future periods. The table appears at the end of this press release has more details on the reconciliations between GAAP financial measures that are comparable to non-GAAP financial measures.
