ISS Supports Aristeia's Case for Change at Sina

– Leading Proxy Advisory Firm Recommends Sina Shareholders Vote on the BLUE Proxy Card to Elect Aristeia Nominee, Thomas J. Manning, to the Board –

Aristeia Capital, L.L.C. (collectively with Aristeia Master, L.P. and certain other affiliates, "Aristeia" or "we" or "us"), a long-term investor in Sina Corporation SINA ("Sina" or the "Company") and currently one of the Company's five largest shareholders, owning approximately 3 million shares, announced today that Institutional Shareholder Services (ISS), the leading independent proxy voting advisory firm, has endorsed Aristeia's case for change and recommended that Sina shareholders vote on the BLUE proxy card to support the election of Aristeia's highly-qualified nominee, Thomas J. Manning, to the Company's Board (the "Board") at the upcoming Annual Meeting of shareholders, which is currently scheduled to be held on November 3, 2017.

ISS concluded that shareholders should vote to elect Thomas J. Manning to the Sina Board, saying:

"The dissident presents a compelling case for adding at least one new independent director to the board. Manning, who brings experience relevant to the company's expansion into online finance as well as a sizable record of public board service in China, seems well-suited to add value to the company."¹

In reaching its conclusion, ISS indicated concern over Sina's growing valuation gap and its shares trading at such a large discount to net asset value ("NAV"), noting:

"[A]n examination of the arguments reveals compelling reasons for shareholders to seek change at the company. Among the most obvious is the rather large valuation discount, the sheer size of which seems to indicate more than a mere holding company discount, especially considering that the company is not a complex conglomerate…a number of shareholders have expressed frustration with trying to understand the company's smaller, but nevertheless significant and growing, portfolio of non-Weibo investments given the company's relative opacity."

The advisory firm also supported Aristeia's thesis that Sina's current Board is not aligned with the best interests of shareholders, acknowledging the Company's poor corporate governance practices, stating:

"There are a number of other governance issues at play…Each of these factors dilutes the board's efficiency as a mechanism for aligning the interests of management with those of shareholders."

Robert H. Lynch, Jr., Partner, Aristeia Capital, L.L.C., said, "The addition of fresh perspectives to the Board at Sina is sorely needed in order to reduce the growing valuation gap that plagues the Company. The fact that ISS supported the election of Aristeia's nominee, Thomas Manning, sends a clear message that Sina's current entrenched Board and lax governance practices have contributed to Sina's shares trading at a massive and growing discount to net asset value. Urgent change is required to address this and other critical issues facing our Company. While we strongly appreciate ISS's support, we remain confident that both of our nominees have the knowledge of the Chinese market as well as the regulatory, investment and governance expertise that is necessary to constructively work with all members of the current Sina Board to unlock value for shareholders, and that voting for both our nominees represents the best path forward for the Company. We look forward to continuing to make our case for change in advance of the Company's Annual Meeting."

We strongly urge Sina's shareholders to vote FOR both of our independent and highly-qualified nominees on the BLUE proxy card and to return it in the postage-paid envelope provided.

Due to the Company's requirement that proxies must be received by it no later than forty-eight (48) hours prior to the Annual Meeting, it is very important that you return your BLUE proxy card to us as soon as possible to ensure that your vote gets counted. If you have already returned a white proxy card to the Company, you can revoke that card by submitting a later-dated BLUE proxy card.
