Tenzing Global Urges Brightcove Stockholders to Hold CEO and Board Accountable for Significant Underperformance by Voting Against David Mendels and Derek Harrar at Upcoming Annual Meeting

SAN FRANCISCO, May 8, 2017

Tenzing Global reminds stockholders that the 2017 Annual Meeting is just 2 days away. Stockholders must express their disappointment in the CEO and Board by a withhold vote against directors Mendels and Harrar. As recently as March, Tenzing Global's stockholder director had been informed by the CEO that Q1 financial performance was tracking to plan, and had not been informed of any weakness in guidance. Based partially on that assurance, Tenzing Global withdrew its nominated alternative slate of directors. Less than 5 days before the Annual Meeting, stockholders learned the magnitude of the continued poor operating performance of the Company under this CEO.

Even though Brightcove has an archaic, democracy-unfriendly plurality voting standard in place for director elections, where just one vote in favor is enough to elect a director, Tenzing Global believes voter turnout against the 2 incumbent directors at this Wednesday's 2017 Annual Meeting will send a clear message to the Board that immediate changes are required and that stockholders will not tolerate the status quo.

Tenzing Global urges stockholders to reject the following directors by voting to "WITHHOLD ALL" on Proposal 1 on the Company's Proxy Card:

• David Mendels, Chief Executive Officer of Brightcove
• Derek Harrar, a director since January 2014

"Tenzing Global has met hundreds of great management teams and boards, with whom we have formed long-standing collaborative relationships that have enabled us to compound our investors' capital at over 13% net of fees since 2013. Brightcove possesses all the components of a successful company: industry-leading products and technologies, a highly recognizable brand, and dedicated employees. At Brightcove, we have been working constructively as long-term stockholders since April 2013, first as an outside stockholder and then as a stockholder director for the last two years," said Chet Kapoor, Portfolio Manager and Managing Partner of Tenzing Global. "Our ideas were met with resistance from a Board that was unwilling to hold the CEO accountable for poor corporate performance. Last week, I was surprised to learn of the sudden weakness at Brightcove subsequent to my resignation from the Board. David Mendels' recent confidence was yet again clearly misplaced. We strongly believe Brightcove can achieve its full potential under a new CEO and a reconstituted Board."

Consistent Poor Execution under David Mendels' Stewardship

The Company delivered extremely disappointing results for its fiscal year 2017 first quarter on May 4, 2017. The Company significantly revised downward its full year guidance at the mid-point for total revenue from $165 million to $153 million, and alarmingly, non-GAAP operating margin from +3% to -5%, and its Non-GAAP earnings per share from +$0.11 to -$0.24. To put those results into a 5-year perspective, the Company presented a target of long-term operating margins of +20% in its 2013 Analyst Day.
