The truth about Saba Setting the record straight Saba has made numerous unsubstantiated claims about BlackRock, your Fund, and your Board—but they do not add up. Myth Saba claims that its actions are in the best interest of CEF shareholders Reality Saba has chosen to use its vast resources to buy large stakes in closed-end funds (CEF), engage in costly proxy fights, and force actions that provide Saba with a quick profit for themselves at your expense. Myth Saba claims BlackRock CEFs aren’t delivering results for investors Reality BlackRock CEFs have delivered consistent long-term value over time, generating $3.6 billion in gains in 2023 alone while paying shareholders $3.1 billion per year via dividends4. We have also repurchased $1.3 billion in shares, generating over $200 million in gains5. Myth Saba claims to be a better CEF manager than BlackRock Reality BlackRock has a 35+ year track record of delivering long-term value for CEF shareholders. At the funds Saba has taken over (BRW, SABA), shareholders are now exposed to riskier strategies, leaving them with a fund that no longer serves their original goals, as well as higher management fees. Saba’s CEF track is marked by failure and underperformance6: BRW Total Shareholder Return6 BRW Morningstar US CEF Bank Loans BlackRock Bank Loans Funds Median Since takeover (6/4/2021 – 5/24/2024) 13.4% 18.0% 30.6% 4 Annualized estimate based on June 2024 dividends for BlackRock closed-end funds 5 BlackRock.
