T1 Energy Inc.

Business Overview & Disclosures

T1 Energy is a solar module and cell manufacturer headquartered in Austin, Texas, having fully pivoted away from its Norwegian battery business with the February 2025 name change. The company had 562 employees (as of 2025-12-31, per its 10-K).

On 2026-06-03, the company entered into a definitive agreement to acquire battery-related asset KORE Power, Inc. (enterprise value of approximately $32M, with an earnout of up to $9.6M in stock over FY2026-2027) (A). Further business details were not available (not obtained).

Valuation (Factual Multiples)

EV/EBITDA was not calculated because trailing-twelve-month adjusted EBITDA is negative to negligible (not obtained). Total debt figures vary by source, from $549.78M (secondary aggregation) to $1.03B (as referenced in the primary earnings release); this is presumed to reflect differing definitions, but the cause was not confirmed.

Peer Comparison

Around March 2026, First Solar filed a petition with the U.S. International Trade Commission for a patent infringement investigation into TOPCon technology, naming 10 companies including T1 as respondents. T1 currently sources cells from non-FEOC-certified overseas vendors, and plans to complete vertical integration into in-house cell production once G2_Austin comes online (A).

Governance & Major Shareholders

The CEO and Chairman of the Board is Daniel Barcelo (took office 2024-11), and all 8 directors were elected at the 2026-06-17 annual shareholders meeting. Shares outstanding were 279,271,380 (as of 2026-05-08, per the cover page of the SEC 10-Q, A).

Shares outstanding increased from 155.9 million at end-2024 to 279.3 million by 2026-05 (A), driven by a combination of a December 2025 public offering (32.52 million shares at $4.95/share), issuance of 5.25% convertible notes ($161M), and the Trina Solar debt settlement (including a $274.0M cash payment, among other terms).

Ownership & Short Interest

Institutional ownership (based on 13F filings, snapshots around 2026-07) varies considerably by data aggregator, from 51.6% to 68.0%, presumably due to differences in methodology (13F-only vs. 13F+13D/G, etc.), though this could not be officially reconciled (secondary source).

Short interest as a percentage of float was approximately 21.9%-24.3% as of the most recent settlement date (secondary source, figures vary by vendor), with days-to-cover of approximately 1.3-1.4 days. Following the 2026-05-19 short-seller report, volume spiked to approximately 83 million shares on 2026-05-20 (about 4.7x the 3-month average). The 2026-07-17 volume of 40,229,017 shares is approximately 1.19x the 20-day average volume (approximately 33.94 million shares).

Insider trading (Form 4) shows director Einar G. Kilde disposed of 261,131 shares on 2026-05-28 and 51,540 shares on 2026-05-29. Trina Solar (Schweiz) AG acquired an additional 4,274,704 common shares on 2026-01-21 under contractual anti-dilution provisions.

Macro Environment

The U.S. federal funds rate is 3.50-3.75% (held steady at the 2026-06-17 FOMC meeting), and the 10-year Treasury yield is 4.55% (as of 2026-07-17). Interest rate levels indirectly affect T1's module order volumes through the financing costs of downstream utility-scale solar developers.

New FEOC (Prohibited Foreign Entity) rules were introduced for the IRA 45X production tax credit in 2026, but T1 retained eligibility through its late-2025 restructuring of Trina Solar-related equity, debt, and IP, and in early 2026 completed its first sale of $160M in 45X tax credits (at 91 cents per dollar) (A).

On 2025-04-21, the U.S. Department of Commerce issued final antidumping and countervailing duty determinations on solar cells from Cambodia, Thailand, Vietnam, and Malaysia (up to 3,521% for Cambodia, among others), and on 2026-02-06, the Section 201 safeguard tariff that had been in effect for 8 years expired (A). Reduced Low-Cost Import Competition

The EIA reported that U.S. electricity consumption is projected to grow approximately 2% annually from 2024-2026, driven by new demand from data centers, semiconductor plants, and battery factories (2026-04-08, AEO2026). Meanwhile, U.S. solar installations in Q1 2026 totaled 7.8GWdc, down -27% year-over-year (utility-scale -34%) (SEIA/Wood Mackenzie, released 2026-06).

Risk Factors

• Customer concentration: a single customer accounted for 78% of total net revenue and 100% of accounts receivable balance in FY2025 (10-K, A).
• RWE Clean Energy (via its subsidiary RWE Investco EPC MGMT) terminated its long-term supply agreement on 2025-12-19 and filed suit against T1 in California state court on 2026-01-07. T1 has filed a counterclaim and separately sued RWE's parent company in New York state court seeking up to $100M under a guarantee (A).
• On 2026-05-19, short seller Fuzzy Panda Research published a report alleging concerns related to China-linked supply chains and tax credit eligibility (secondary source, unverified short-seller claims). Reports indicate the Chief Accounting Officer was replaced approximately two weeks later, though the company's official reason has not been confirmed (secondary source).
• In March 2026, First Solar filed a petition with the U.S. International Trade Commission for a patent infringement investigation into TOPCon technology, naming 10 companies including T1 as respondents (A).
• Solar module production is currently concentrated at a single U.S. facility (G1_Dallas), and the company relies on a small number of suppliers for key raw materials, components, and manufacturing equipment (10-K, A).
• Losses have continued, including a $(380.8)M net loss in 2025 and a $(20.4)M net loss in Q1 2026, and approximately $225M in additional financing is needed to complete G2_Austin Phase 1 (A).
