Eos Energy Shares Rebound After CEO and Director Buy Stock Following Guidance Miss

Insider share purchases follow a $1 billion-plus selloff after a guidance miss.

Overview

  • Regulatory filings show CEO Joe Mastrangelo bought 60,000 shares at $5.75 each for roughly $345,000, while Director Alexander Dimitrief purchased 15,000 shares at $6.04.
  • The stock rose 11.4% to $6.75, marking a third straight advance as investors reacted to the insider buying.
  • Last week’s 2025 results showed $114.2 million in revenue versus guidance of $150 million to $160 million, leading to a roughly 39% one-day drop that erased over $1 billion in market value.
  • Eos posted a record $58 million in fourth-quarter revenue with sharply higher deliveries, alongside a $969.6 million full-year net loss driven by about $746.8 million in non-cash charges and an adjusted EBITDA loss of $219.1 million.
  • Management now targets $300 million to $400 million in 2026 revenue after completing about $1.06 billion of financing in November through convertible notes and equity sold at $12.78 per share.
