Arnold Cynthia A 4

What Happened Cynthia A. Arnold, a member of Fluence Energy's Board of Directors, received an award of 10,658 restricted stock units (RSUs) on March 12, 2026. The RSUs are recorded at $0.00 in the Form 4 because they are a stock-based grant (derivative award) rather than an open-market purchase or sale.

Key Details

• Transaction date: 2026-03-12; transaction type: A (award/grant); amount: 10,658 RSUs; price recorded: $0.00.
• Each RSU is a contingent right to one share of Fluence Class A common stock (see footnote F1).
• Vesting: RSUs vest in full on March 12, 2027, contingent on Ms. Arnold's continued board service; RSUs have no expiration date (footnote F2).
• Shares owned after the transaction: not specified in the filed report.
• Filing posted: Form 4 filed 2026-03-16 (investors may compare this timing to the two-business-day reporting requirement under Section 16).

Context RSU grants to directors are a common form of compensation and are not direct purchases or sales of stock. These units convert to actual shares only upon vesting (here, one year later), so they do not represent immediately tradable shares unless sold after vesting. The filing is informational and should be viewed as compensation disclosure rather than a direct insider market signal.
