View on StockTwits ↗$GWH Who do you think $GWH is merging with? I asked ChatGPT to analyze the clues from ESS’s press release/earnings call, and it thinks FlexGen is the strongest candidate. If true, this could be very interesting: FlexGen already supports 25+ GWh of BESS, has strong commercial execution, HybridOS, and AI data-center exposure. Add ESS’s iron-flow tech, Bridge, and sodium-ion partnership with Alsym, and you could get a serious U.S. energy-storage platform. Maybe an early-stage “Bloom Energy type” setup — a beaten-down power infrastructure story just as AI power demand catches up. SoftBank is also still a major $GWH shareholder with board representation. Pure speculation for now, but the setup is interesting.
