SLDP Stock Surges 600%, Then Slides After Q3: What’s Next for Solid Power?

In a year marked by extraordinary gains across select energy tech stocks, SLDP stock has quickly become one of the most closely watched tickers in the battery innovation space. Solid Power Inc. has seen its share price surge nearly 600% over the past twelve months. However, the explosive rally cooled off after the company’s third-quarter earnings report, which revealed revenue shortfalls and led to a swift drop in share price. Here’s what’s behind the stock’s roller-coaster year, and what investors are watching next for SLDP stock.

Q3 2025 Earnings Review and Stock Performance

Solid Power announced its financial results for the third quarter of 2025 on November 4. The company reported a net loss per share of $0.14—perfectly matching Wall Street’s forecast. However, revenue came in at $4.56 million, underperforming analyst estimates of $5 million, indicating a revenue miss of approximately 8.8%. Following the announcement, SLDP stock closed at $5.61, experiencing a short-term decline, but the subsequent trend has been firmly upward.

Key Stock Performance Metrics:

• 12-Month Price Jump: SLDP stock has skyrocketed 577.01% over the past year.

• Year-to-date Increase: The shares surged 197.09% since January.

• 6-Month Momentum: Remarkably, SLDP gained 396.9% over just the past six months.

• Recent 3-Months Growth: Shares advanced 43.97% in the last quarter alone.

• Market Capitalization: The company’s market value has risen sharply, reaching $1.42 billion—a substantial change from earlier in the year.

• Balance Sheet: Despite the quarterly revenue miss, Solid Power maintains a robust financial footing with a current ratio of 19.33 and revenue growth at 14.83%.

Investors continue to price in strong future growth for SLDP, trading it above calculated fair value according to third-party analysis. The consistent upward pressure on the share price throughout 2025, including new 52-week highs, underscores confidence in the company’s long-term business model and technology edge.

Institutional Holdings: Growing Confidence in SLDP

Institutional investors and hedge funds are increasingly establishing positions in Solid Power, demonstrating professional confidence in SLDP’s future prospects.

Recent institutional movements include:

• Goldman Sachs Group Inc.: Expanded holdings by 12.7% in Q1, now owning 894,120 shares (worth ~$939,000 after purchasing an additional 100,939 shares).

• Creative Planning and American Century Companies Inc.: Both initiated new stakes in Q2, valued at around $26,000 and $27,000, respectively.

• Prudential Financial Inc.: Boosted its position by 69.7% in Q2, now holding 17,480 shares.

• Brown Advisory Inc.: Also took a new position in Q2, valued at approximately $33,000.

As of now, 33.66% of SLDP shares are held by institutional investors and hedge funds, a significant vote of confidence in the firm's growth and resilience.

The Surging Demand for Solid-State Batteries

The development of solid-state battery (SSB) technology is transitioning quickly from laboratory research to scalable commercial production. According to industry analysis by TrendForce, close to 100 companies globally have now announced plans to manufacture solid-state batteries, collectively targeting a production capacity that exceeds 100 GWh. Some semi-solid battery variants have already reached mass production scales.

Currently, the adoption of all-solid-state batteries (ASSBs) remains mostly in the pilot production phase, producing several hundred megawatt-hours (MWh), where manufacturers are focused on validation and optimization. Broader use is underway in non-automotive settings, such as industrial robots, medical devices, and semiconductor manufacturing equipment. In the automotive sector, wider adoption is anticipated around 2027, as pilot applications give way to larger-scale integration.

Semi-solid-state batteries have already entered the market through specific electric vehicle models from companies including Dong Feng, NIO, IM, SERES, Voyah, and SAIC. Meanwhile, major automakers such as BMW, Mercedes-Benz, Stellantis, Chery, and Hyundai are actively testing vehicles that incorporate all-solid or semi-solid battery cells. In addition to automotive applications, energy storage is emerging as a primary use case, particularly in China, where semi-solid lithium iron phosphate (LFP) batteries are being introduced for stationary storage—expected to account for more than half of sector demand through 2026. Rapid uptake is also forecasted in segments such as consumer electronics, humanoid robots, and electric vertical takeoff and landing (eVTOL) aircraft, as a broader range of industries seek batteries with improved safety and energy density.

SLDP’s Business Expansion: Partnerships with BMW and Samsung SDI

Solid Power’s business strategy includes partnerships with leading auto and battery firms aimed at accelerating the commercialization of solid-state battery technology. The collaboration between BMW and Solid Power has been ongoing since 2016 under a joint development agreement, with BMW making a direct investment in Solid Power in May 2021. Progress in their partnership was marked by BMW’s receipt of initial prototype solid-state cells from Solid Power for qualification testing at the end of October 2023. By May 2025, these SSB cells had advanced to road testing in a BMW i7 prototype vehicle. Additionally, BMW established a prototype line for manufacturing solid-state cells at its Parsdorf facility in Germany, incorporating technology from Solid Power.

The alliance was further strengthened in late 2025 when Samsung SDI joined the project. Samsung SDI is set to integrate Solid Power’s sulfide-based solid electrolytes into its own cell production processes, with the aim of evaluating these cells according to criteria set in collaboration with BMW. Samsung SDI has publicly stated its ambition to become a leader in the commercialization of all-solid-state batteries by industrializing this technology, which is viewed as critical for next-generation EVs due to their enhanced safety profile and higher energy density.

With this three-way partnership, Solid Power is positioned at the intersection of automotive and advanced battery manufacturing, potentially playing an important role as these technologies approach market maturity and scale.

SLDP Stock Price Prediction and Analyst Ratings

Market analysts remain divided in their outlook for SLDP, reflecting both the potential and the challenges of disruptive battery tech investing:

• Needham & Company LLC: Upgraded price target from $2.00 to $4.00 with a “Buy” rating following recent business progress.

• Weiss Ratings: Maintained a “Sell (D-)” rating, citing risks and near-term uncertainty.

• Consensus: The current consensus rating is “Hold,” with an average price target of $4.00 according to MarketBeat.

It's important to note that the stock is now trading significantly above the consensus price target, near $5.61 at last earnings and climbing further post-report. This premium reflects investor confidence in long-term prospects, surging industry demand, and the partnerships with BMW and Samsung SDI, but also introduces valuation risk if execution falters or commercialization is delayed.

Conclusion

Solid Power Inc. (SLDP) is at the epicenter of the fast-evolving solid-state battery sector, boasting a year of record-breaking stock appreciation and validation from major carmakers and institutional investors. While the company faces near-term revenue challenges and mixed analyst sentiment, the trajectory of the solid-state market, ongoing strategic partnerships, and a robust balance sheet position SLDP for long-term growth and potential leadership in next-generation battery technology. Investors should weigh the promise of solid-state innovation against the inherent risks of emerging tech when evaluating SLDP stock.
