FTC Solar (NASDAQ: FTCI) revenue jumps 149% as margins improve but losses stay high

Rhea-AI Filing Summary

FTC Solar reported strong revenue growth but remained unprofitable in Q4 2025. Revenue reached $32.9 million, up 26.2% from the prior quarter and 148.9% year-over-year, landing within guidance. GAAP gross margin improved to 21.0%, while Non-GAAP gross margin was 23.4%, one of the highest levels in company history.

Despite this, GAAP net loss widened to $33.7 million, driven largely by a $26.4 million loss from the change in fair value of warrant liabilities and higher interest expense. Adjusted EBITDA loss narrowed sharply to $0.3 million from $9.8 million a year earlier, reflecting better underlying operations.

The company highlighted 2025 full-year revenue growth of more than 110% and a contracted backlog of about $491 million, excluding two new multi-year supply agreements totaling roughly 1.84 gigawatts of solar trackers in the U.S. and South Africa. For Q1 2026, FTC Solar guides revenue to $20–$25 million, with modest Non-GAAP gross margin and a larger Adjusted EBITDA loss as seasonality and earlier regulatory delays weigh on results.

Positive

• Rapid top-line and margin improvement: Q4 2025 revenue reached $32.9 million, up 148.9% year-over-year, while Non-GAAP gross margin improved to 23.4% from a loss in the prior-year quarter, driving Adjusted EBITDA close to break-even.
• Strong growth pipeline: Contracted backlog is approximately $491 million, and FTC Solar announced new multi-year supply agreements totaling about 1.84 gigawatts of tracker volume in the U.S. and South Africa, supporting future revenue visibility.

Negative

• Large GAAP losses and warrant overhang: Q4 2025 GAAP net loss was $33.7 million, heavily impacted by a $26.4 million loss from warrant liability revaluation, and the warrant liability rose to $74.5 million.
• Weakened equity position: As of December 31, 2025, stockholders’ equity was a deficit of $40.3 million, reflecting cumulative losses and creating balance sheet pressure despite higher revenue.

Insights

Renewable energy equity analyst

Core operations improved sharply with strong growth, but headline losses remain large.

FTC Solar delivered a substantial Q4 2025 rebound. Revenue rose to $32.9 million, up 148.9% year-over-year, and Non-GAAP gross margin reached 23.4% versus a deep loss a year earlier. Adjusted EBITDA loss narrowed to $0.3 million, signaling much closer to break-even operations.

However, GAAP net loss expanded to $33.7 million, mainly from a $26.4 million loss on warrant liability fair value and higher interest costs. The balance sheet shows a $74.5 million warrant liability and a stockholders’ deficit of $40.3 million, which may constrain flexibility until profitability improves.

Operationally, bookings momentum looks robust. Full-year revenue grew over 110%, and contracted backlog stands at about $491 million, excluding new agreements for about 1.84 gigawatts of trackers. Q1 2026 guidance of $20–$25 million revenue and an Adjusted EBITDA loss of $5.9–$9.6 million reflects seasonality and prior regulatory delays, so later 2026 quarters will be important to see if growth and margins re-accelerate as expected.

FTC Solar Announces Fourth Quarter 2025 Financial Results

Fourth Quarter Highlights and Recent Developments

•Fourth quarter revenue of $32.9 million, up 26% q/q, 148.9% y/y, in line with target guidance

•Gross margin improvement of approximately 1,500 basis points q/q and 4,900 points y/y

•Awarded 1GW supply agreement with leading developer for 1P and 2P trackers in U.S.

•Secured 840MW supply agreement with Lubanzi for 1P and 2P trackers in South Africa

AUSTIN, Texas — March 5, 2026– FTC Solar, Inc. (Nasdaq: FTCI), a leading provider of solar tracker systems, today announced financial results for the fourth quarter that ended December 31, 2025.

“I’m pleased to share that our fourth quarter results came in at the high-end of our target ranges and we continued to position the company for long-term success,” said Yann Brandt, President and Chief Executive Officer of FTC Solar. “Quarterly revenue grew 26% sequentially, and nearly 150% year-over-year, gross margin was one of the highest in company history, and we posted our best Adjusted EBITDA performance in six years.

On the commercial front, our compelling product lineup has led to significant advancement in customer positioning, including positive and accelerating net bookings for the period, new multi-year supply agreements, and being added to multiple Tier 1 approved vendor lists. FTC is well positioned to gain significant share in the dynamic tracker market.”

“Our fourth quarter results were a fitting end to a full-year 2025 that saw us grow revenue by more than 110%, as we continued our recovery, launched compelling new product features, and expanded our pipeline with more customers and larger projects. While the company is not immune to the impacts of regulatory uncertainty-related booking delays in 2025, our commercial traction continues to improve. Overall, we expect to see continued acceleration in our bookings in 2026 and to continue outpacing industry revenue growth rates as our recovery progresses.”

Fourth Quarter Results

Total fourth-quarter revenue was $32.9 million, which was in line with our target range. This revenue level represents an increase of 26.2% compared to the prior quarter and an increase of 148.9% compared to the year-earlier quarter.

GAAP gross profit was $6.9 million, or 21.0% of revenue, compared to gross profit of $1.6 million, or 6.1% of revenue, in the prior quarter. Non-GAAP gross profit was $7.7 million or 23.4% of revenue, and represented one of the highest levels in company history, and our best as a public company. This compares to Non-GAAP gross loss of $3.4 million in the prior-year period.

GAAP operating expenses were $10.6 million. On a Non-GAAP basis, operating expenses were $8.2 million. This compares to Non-GAAP operating expenses of $7.4 million in the year-ago quarter. 

GAAP net loss was $33.7 million or $2.23 per diluted share, compared to a loss of $23.9 million or $1.61 per diluted share in the prior quarter and a net loss of $12.2 million or $0.96 per diluted share (post-split) in the year-ago quarter. Adjusted EBITDA loss, which excludes approximately $33.5 million for (i) a loss from the change in fair value of the warrant liability, (ii) loss on extinguishment of debt, (iii) certain CEO transition costs, and (iv) costs for a special stockholders' meeting in September 2025 and other non-cash items, was $0.3 million, compared to Adjusted EBITDA losses of $4.0 million1 in the prior quarter and $9.8 million in the year-ago quarter.

Subsequent Events

In addition to its financial results, the company also announced that it has been selected by a leading developer and operators of wind and solar farms, to supply approximately 1 gigawatt of solar trackers for multiple project sites in the U.S., over an initial three-year term. The customer is expected to utilize a combination of FTC’s 1P (Pioneer) and 2P (Voyager) trackers, as well as FTC’s innovative SunPath performance-enhancing software.

On February 23, the company announced a three-year supply agreement with Lubanzi Inala, a leading South African solar procurement company part of the EPC consortium Green Axis Africa. The agreement calls for FTC Solar to supply Lubanzi with approximately 840 megawatts of solar trackers over the 3-year term. The projects are expected to be located in South Africa and utilize a combination of 1P and 2P tracker technologies. The first project under this agreement is expected to begin in mid-2026.

The contracted portion of the company's backlog2, which does not include any portion of the two agreements noted above, which are not yet contracted, now stands at approximately $491 million.

Outlook

After a very strong conclusion to 2025, which included signing nearly half of our bookings for the year in the fourth quarter, we enter the first quarter of 2026 with a bit of seasonality and leftover effects of the regulatory uncertainty-related project delays in mid-2025. At the midpoint of our target range for the first quarter, we are guiding for an 8% year-over-year increase in revenue, with significant improvements in gross margin and Adjusted EBITDA. This should also compare favorably relative to the industry.

The new bookings from 2025, as well as the conversion of prior year MSAs to contracted, should begin to layer in the coming quarters, resulting in significant and meaningful growth throughout the year that we expect will outpace the market thanks to our positioning with customers, AVL gains and competitiveness from our product portfolio.

Footnotes

1. A reconciliation of prior quarter Non-GAAP financial measures to the nearest comparable GAAP measures may be found in Exhibit 99.1 of our Form 8-K filed on November 12, 2025.

2. The term ‘backlog’ or ‘contracted and awarded’ refers to the combination of our executed contracts (contracted) and awarded orders (awarded), which are orders that have been documented and signed through a contract, where we are in the process of documenting a contract but for which a contract has not yet been signed, or that have been awarded in writing or verbally with a mutual understanding that the order will be contracted in the future. In the case of certain projects, including those that are scheduled for delivery on later dates, we have not locked in binding pricing with customers, and we instead use estimated average selling price to calculate the revenue included in our contracted and awarded orders for such projects. Actual revenue for these projects could differ once contracts with binding pricing are executed, and there is also a risk that a contract may never be executed for an awarded but uncontracted project, or that a contract may be executed for an awarded but uncontracted project at a date that is later than anticipated, or that a contract once executed may be subsequently amended, supplemented, rescinded, cancelled or breached, including in a manner that impacts the timing and amounts of payments due thereunder, thus reducing anticipated revenues. Please refer to our SEC filings, including our Form 10-K, for more information on our contracted and awarded orders, including risk factors.

3. We do not provide a quantitative reconciliation of our forward-looking Non-GAAP guidance measures to the most directly comparable GAAP financial measures because certain information needed to reconcile those measures is not available without unreasonable efforts due to the inherent difficulty in forecasting and quantifying these measures as a result of changes in project schedules by our customers that may occur, which are outside of our control, and the impact, if any, of credit loss provisions, asset impairment charges, restructuring or changes in the timing and level of indirect or overhead spending, as well as other matters, that could occur which could significantly impact the related GAAP financial measures.

Notes to Reconciliations of Non-GAAP Financial Measures to Nearest Comparable GAAP Measures

We utilize Adjusted EBITDA, Adjusted Net Loss, and Adjusted EPS as supplemental measures of our performance. We define Adjusted EBITDA as net loss plus (i) provision for (benefit from) income taxes, (ii) interest expense, less interest income, (iii) depreciation expense, (iv) amortization of intangibles, (v) stock-based compensation, (vi) loss from changes in the fair value of our warrant liability, (vii) loss on extinguishment of debt, and (viii) Chief Executive Officer ("CEO") transition costs, non-routine legal fees, costs associated with our reverse stock split and special stockholders' meeting, severance and certain other costs (credits). We also deduct the contingent gains arising from earnout payments and project escrow releases relating to the disposal of our investment in an unconsolidated subsidiary and gains from changes in fair value of our warrant liability from net loss in arriving at Adjusted EBITDA. We define Adjusted Net Loss as net loss plus (i) amortization of debt discount and issue costs and intangibles, (ii) stock-based compensation, (iii) loss from changes in the fair value of our warrant liability, (iv) loss on extinguishment of debt, (v) CEO transition costs, non-routine legal fees, costs associated with our reverse stock split and special stockholders' meeting, severance and certain other costs (credits), and (vi) the income tax expense (benefit) of those adjustments, if any. We also deduct the contingent gains arising from earnout payments and project escrow releases relating to the disposal of our investment in an unconsolidated subsidiary and gains from changes in fair value of our warrant liability in arriving at Adjusted Net Loss. Adjusted EPS is defined as Adjusted Net Loss on a per share basis using our weighted average diluted shares outstanding.

Non-GAAP gross profit (loss), Non-GAAP operating expense, Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS are intended as supplemental measures of performance that are neither required by, nor presented in accordance with, U.S. generally accepted accounting principles (“GAAP”). We present these Non-GAAP measures, many of which are commonly used by investors and analysts, because we believe they assist those investors and analysts in comparing our performance across reporting periods on an ongoing basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we use Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS to evaluate the effectiveness of our business strategies.

Non-GAAP gross profit (loss), Non-GAAP operating expense, Adjusted EBITDA, Adjusted Net Loss and Adjusted EPS should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP, and you should not rely on any single financial measure to evaluate our business. These Non-GAAP financial measures, when presented, are reconciled to the most closely applicable GAAP measure as disclosed below.
