Solid Power (SLDP) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Solid Power published the results on November 3, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison.

• The revenue figure here is Solid Power's total revenue and grant income, the top line of its income statement; grant income comes from a U.S. Department of Energy assistance agreement. Solid Power reports in thousands; figures here are in millions.
• Q2 2026 total revenue and grant income was negative ($268 thousand) as first reported. Q4 2025 revenue is derived from annual minus nine-month figures, because the Q4 2025 release reports full-year results only.

How Solid Power splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Solid Power's Revenue revenue was $0.2 million in Q3 2026, down 93% from $3.7 million in Q3 2025, 20% of total revenue.
• Solid Power's Grant income revenue was $1.0 million in Q3 2026, up 18% from $0.8 million in Q3 2025, 80% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

Solid Power gives no revenue or EPS outlook. Its guidance covers cash investment for the year.

In its Q3 2026 release, Solid Power said:

“Management has reduced its expected 2026 cash investment guidance to be in the range of $75 million to $85 million compared to its prior range of $85 million to $100 million.”

“The revised outlook reflects our continued focus on driving innovation, building internal capabilities and supporting our partners and customers while optimizing expenses.”

This is the company's own guidance as of Nov 3, 2026, quoted as given. Walnut does not make forecasts of its own. Analyst estimates for the coming quarters are on the SLDP forecast page.

Revenue and diluted EPS for the last 5 quarters. Each date links to that quarter's release.

Total revenue and grant income and basic and diluted loss per share, each as first reported in that quarter's release. Q4 2025 is 2025 annual total revenue and grant income ($21.7 million) minus the nine-month figure ($18.1 million); the Q4 2025 release gives no fourth-quarter EPS.

We do not hold a confirmed date for Solid Power's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Nov 3, 2026

Solid Power develops sulfide-based solid electrolyte for solid-state batteries and has no commercial product revenue yet. Total revenue and grant income was $1.2 million in Q3 2026, against $4.6 million a year earlier: $243 thousand of revenue and $981 thousand of grant income. (Solid Power Q3 2026 release, Nov 3, 2026)

The revenue mostly consisted of performance on the SK On R&D license, which Solid Power recognizes by the cost-to-cost method as it works toward its obligations. Solid Power put the $3.3 million decrease down largely to the timing of performance milestones achieved under customer arrangements a year earlier, and it expects revenue for the rest of 2026 to keep falling against prior-year periods while it commissions its MOBIUS line. (Solid Power Form 10-Q, Q3 2026, Nov 4, 2026)

Grant income comes from an assistance agreement with the U.S. Department of Energy, which will provide up to $50 million toward equipment for continuous production of sulfide-based solid electrolyte. That equipment is MOBIUS, which will add 45 metric tons of annual electrolyte capacity for a total of 75 metric tons, with full commissioning expected by year-end 2026.

Solid Power provided electrolyte to customers including Samsung SDI and SK On in the quarter, is discussing a potential joint venture for commercial-scale electrolyte production in the Republic of Korea, and is pursuing drone, defense and humanoid robotics applications alongside EVs.

Solid Power reports GAAP EPS only. Its net loss was $24.4 million, or $0.11 per share, in Q3 2026, against $25.9 million, or $0.14, a year earlier. The operating loss widened to $29.8 million from $24.4 million as revenue fell and selling, general and administrative expense rose to $9.8 million from $7.1 million. Against Q2 2026, operating expenses rose to $31.1 million from $30.0 million, which Solid Power attributed to strategic consulting fees. (Solid Power Q3 2026 release, Nov 3, 2026)

Non-operating items narrowed the loss. Interest income was $4.0 million, and the change in fair value of warrant liabilities was a $1.6 million gain, against a $3.5 million loss a year earlier. (Solid Power Q3 2026 release, Nov 3, 2026)

The per-share loss also fell because the share count grew: weighted average shares were 228,196,750, against 182,350,071. In the first quarter of 2026 Solid Power issued 22,807,018 shares in a registered direct offering for net proceeds of $121.3 million. (Solid Power Q3 2026 release, Nov 3, 2026; Solid Power Form 10-Q, Q3 2026, Nov 4, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Solid Power gives no revenue or EPS outlook. It cut its 2026 cash investment guidance to $75 million to $85 million, from $85 million to $100 million. Cash investments were $21.5 million in Q3 2026 and $56.6 million year to date. (Solid Power Q3 2026 release, Nov 3, 2026)

Total liquidity was $397.6 million at September 30, 2026, $23.3 million of cash and cash equivalents and $374.3 million of available-for-sale securities, and Solid Power has no debt. Q3 2026 capital expenditures were $4.7 million, mostly for MOBIUS. (Solid Power Q3 2026 release, Nov 3, 2026)

A consensus figure is the average of the models published by the analysts who cover Solid Power, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Solid Power's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning SLDP is on is SLDP a buy or a sell?, what analysts expect next is on the SLDP forecast, and what the company does is on the Solid Power (SLDP) stock page.

Every number on this page can be traced to a document Solid Power published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
