Black Rock Coffee Bar, Inc. 8-K

What Happened
Black Rock Coffee Bar, Inc. (BRCB) announced it entered into an irrevocable proxy dated March 18, 2026 with four trusts that are Class C common shareholders (the “Proxy Parties”): Jacob V. Spellmeyer 2021 Trust, Juliet A. Spellmeyer 2021 Trust, Bryan D. Pereboom 2021 Trust, and Nicole R. Pereboom 2021 Trust. Under the Proxy (and subject to an existing Voting Agreement dated September 11, 2025), the Company, its Chief Executive Officer or other designees are authorized to vote all Class A, Class B and Class C shares held or controlled by the Proxy Parties and to exercise all related voting and consent rights.

Key Details

• Proxy date: March 18, 2026; filing: Form 8-K filed March 20, 2026.
• Proxy Parties: four 2021 trusts (Spellmeyer and Pereboom family trusts) holding Class C common stock.
• Scope: covers all Class A, B and C common stock held by or under voting control of the Proxy Parties (the “Covered Shares”).
• Duration: the voting power is granted until the later of (a) two years from March 18, 2026 (i.e., March 18, 2028) or (b) termination of the September 11, 2025 Voting Agreement.
• Authority granted: company, CEO or designated designees act as attorney-in-fact and proxy to vote, consent and exercise similar rights with respect to the Covered Shares.

Why It Matters
This agreement shifts voting control of the specified shares to the company (via the CEO or its designees) for a multi-year period, which can affect governance decisions such as board elections, corporate approvals and other shareholder votes. For investors, the filing is material because it changes who will exercise voting power over those Class C shares and could influence future corporate actions; monitor future filings for any related board or transaction disclosures.
