Plus, von Heynitz still retains a meaningful position.<br/><br/>More importantly for investors, Fluence is scaling rapidly, with fiscal first-quarter revenue surging 154% year over year to about $475 million, driven by strong demand for grid-scale storage. That growth is backed by a record $5.5 billion backlog and more than $750 million in new orders during the quarter, giving visibility into near-term revenue. Meanwhile, management is guiding for roughly $3.2 billion to $3.6 billion in revenue this year, with improving profitability expectations.<br/><br/>In other words, insider selling here is not the story. And with shares of the stock up a staggering 200% over the past year, the real question is whether Fluence can convert its backlog and demand tailwinds into sustainable margins as the energy storage market matures.</p><h2>Should you buy stock in Fluence Energy right now?</h2>
