Eos Energy Enterprises (EOSE) shares fell sharply Friday following a planned $150 million rights offering. The company will use the capital to fund its stake in the Frontier Power USA joint venture with Cerberus Capital Management.

The drop follows a strong rally earlier in the week. A surprise first-quarter profit fueled that previous surge. The initial partnership announcement with Cerberus also drove earlier gains.

Investors are now prioritizing concerns over share dilution. The market is also evaluating execution risks associated with the new financing deal.
