Key Highlights

  • The Wednesday, October 28, 2026 snapshot ranks these names by how far they climbed before the open. Ultralife Corporation (NASDAQ:ULBI) is up 143.87% and Elong Power Holding Limited (NASDAQ:ELPW) 38.11%, the only two with a company announcement dated within a day of the session.
  • CBAK Energy Technology (NASDAQ:CBAT) gained 9.57%, Forge Nano Holdings (NASDAQ:NANO) 9.21% and Solidion Technology (NASDAQ:STI) 9.00%, leaving those three within 0.57 of a point of each other.
  • The group shares a battery or advanced materials theme and little else. One is being bought for cash, one has shifted into consumer electronics distribution, and three moved with no dated company news.
  • Quotes are thin and will shift before the 9:30 a.m. ET open, so treat each figure as a snapshot and read the ranking as a measure of move size only.

Ultralife Corporation (NASDAQ:ULBI): a fixed cash price sets the level

Ultralife Corporation (NASDAQ:ULBI) builds batteries, energy products and communications systems. Pre-market it changed hands at USD 15.51 on Wednesday, October 28, 2026. Tuesday's company release disclosed that EnerSys will acquire every outstanding share for USD 16.00 in cash, a transaction worth roughly USD 320 million once assumed net debt is included. The release describes that price as 166% above the Monday, October 26, 2026 close, which points to a prior close near USD 6.02. The snapshot move points to about USD 6.36, so the earlier close lies between those two values.

Second-quarter results released on Friday, August 7, 2026 showed revenue of USD 47.9 million, a 1.3% decline, alongside a record backlog of USD 117.5 million. With cash fixed as the consideration, the stock now tracks the likelihood and timing of closing rather than operating results. The quote sits about 3.1% under the offer, a calculation from two published numbers. The tender has not begun, requires a majority of shares to be tendered and needs regulatory clearance, and closing is targeted for the first quarter of calendar 2027.

Elong Power Holding Limited (NASDAQ:ELPW): a distribution deal with a razor-thin margin

Elong Power Holding Limited (NASDAQ:ELPW) exited its lithium battery operations in March 2026 and now earns distribution income. Its pre-market price of USD 3.37 implies a prior close near USD 2.44. Wednesday, October 28, 2026 brought a release from its Hong Kong unit, which signed a one-year deal worth USD 25.5 million to distribute smart consumer electronics. The first delivery is roughly USD 0.84 million, and the contract is large compared with half-year revenue of USD 2.9 million.

A release dated Tuesday, October 6, 2026 showed gross profit of just USD 8,994 on that revenue, a 0.3% margin, and a continuing-operations loss of USD 2,110,295. The reported net income of USD 20,494,107 comes from a one-off disposal gain, not from running the business. Investors also face dilution from offerings in July and August 2026, Nasdaq compliance questions after 1-for-80 and 1-for-45 reverse splits in 2026, and a public float of roughly 805,500 shares.

CBAK Energy Technology (NASDAQ:CBAT): a bounce with no dated news

CBAK Energy Technology (NASDAQ:CBAT) produces lithium-ion cells for light electric vehicles, grid storage and backup power. The pre-market quote of USD 0.9533 followed a 5.74% dip to USD 0.79 on Tuesday, October 27, 2026. Nothing company-specific dated Wednesday, October 28, 2026 or earlier surfaced, and its newest release is from Wednesday, October 14, 2026. Thin trading and a broader rally in cheap stocks are the likeliest drivers, an inference.

The first-quarter report of Monday, May 18, 2026 posted net revenues of USD 69,617,992, up 99.3%, a 1.5% gross margin and a net loss attributable to shareholders of USD 9,287,372. Management also pointed to an order worth about USD 96 million from an Indian two- and three-wheeler manufacturer, plus a 12 GWh project in Nanjing that hinges on funding. The main hazards are thin margins, the capital needed for capacity and a price near USD 1.00. That last point matters for Nasdaq minimum bid price standards as background only, since no notice has been disclosed.

Forge Nano Holdings (NASDAQ:NANO): a fresh listing finds its feet

Forge Nano Holdings (NASDAQ:NANO) is an advanced manufacturer focused on chips for the AI era and batteries for defence use. It quoted at USD 5.10 pre-market, after a 5.40% gain to USD 5.27 on Tuesday, October 27, 2026. A release dated Thursday, October 22, 2026 confirmed that the merger with Archimedes Tech SPAC Partners II had closed. Nothing dated on or just before the session came with this move, so early volatility in a recently listed name is the likelier explanation, an inference.

Terms disclosed on Tuesday, April 21, 2026 set a pre-money equity value near USD 1.2 billion, up to USD 342 million of gross proceeds, an off-take agreement worth USD 84 million and a USD 100 million Department of Energy grant. The releases contain no revenue, net loss or cash figures. The named risks are an earnout of up to USD 900 million that could add shares, a thin public float and the challenge of scaling manufacturing.

Solidion Technology (NASDAQ:STI): a bid still on the table and a cash cushion

Solidion Technology (NASDAQ:STI) develops silicon-rich anode materials and battery cells. Pre-market it traded at USD 4.56, and no company announcement dated on or just before Wednesday, October 28, 2026 came with the move. The latest corporate event is a Monday, October 5, 2026 release restating a non-binding offer below market value to buy Flux Power (NASDAQ:FLUX), which Flux's board rejected on Friday, October 2, 2026. The rise seems to reflect thin liquidity and interest in that bid, though no cause has been stated.

The Thursday, August 6, 2026 release reported quarterly net sales of USD 124,914, a net loss of USD 2.89 million and cash of USD 27.7 million, after a USD 35 million private placement closed on June 9, 2026. Market capitalisation is roughly USD 45 million on a float of about 3.53 million shares, and the Flux bid may never proceed.

Where Things Stand

The five share a battery or advanced materials theme yet moved for distinct reasons. Ultralife Corporation (NASDAQ:ULBI) is pinned to completion of a cash tender, Elong Power Holding Limited (NASDAQ:ELPW) to a thin-margin distribution contract, and CBAK Energy Technology (NASDAQ:CBAT), Forge Nano Holdings (NASDAQ:NANO) and Solidion Technology (NASDAQ:STI) to thin trading, with no dated announcement behind them. Ahead are the Federal Reserve decision later on Wednesday, October 28, 2026, the Ultralife tender launch and Forge Nano's first results as a listed company. Pre-market quotes are snapshots that can shift, and this is not investment advice.
