Tigo Energy, Inc.

What they do

Tigo develops hardware and software that improve safety, energy yield and operating costs of residential, commercial and utility-scale solar systems. It sells primarily through distributors and solar installers, with MLPE products largely manufactured in Thailand and GO ESS production for the U.S. moved from China to Vietnam in October 2025. U.S. net revenue was 23.3% of total net revenue in 2025 and 17.8% in the first half of 2026.

Revenue drivers

• MLPE (module-level power electronics) — Core product line; represented 68.9% of U.S. net revenues in 2025 and 71.6% in the first half of 2026, with substantially all units manufactured in Thailand.
• GO Energy Storage Systems (GO ESS) — Storage product line contributing $2.2 million, or 8.6% of second-quarter 2026 revenue; 27.6% of U.S. net revenues in the first half of 2026, with U.S.-bound production moved to Vietnam.
• Optimized inverter solution (Section 45X/ITC qualified) — U.S.-manufacturing-linked product tied to domestic content incentives; volume shipments now expected to ramp in the fourth quarter of 2026 because of partner operational delays.
• International distribution (EMEA, APAC, LATAM) — EMEA was 73.1% of second-quarter 2026 revenue with Germany the largest market at 22.8%; APAC 10.1%; Americas and LATAM combined 16.8%.

Recent performance

Second-quarter 2026 revenue was $25.4 million, up 5.6% year over year but below guidance. Gross profit was $10.0 million (39.3% of revenue) versus $10.8 million (44.7%) a year earlier, and operating expenses fell to $11.7 million from $12.3 million. GAAP net income was $2.2 million, including a $3.2 million discrete income-tax benefit, compared with a $4.4 million net loss a year earlier; adjusted EBITDA was $52 thousand versus $1.1 million. Inventory fell to $20.6 million from $31.3 million at year-end 2025, and the quarter ended with $16.9 million in cash and $4.1 million drawn on the credit facility.

Strategy

Management is prioritizing U.S. domestic manufacturing and supply-chain diversification, having moved GO ESS production for the U.S. from China to Vietnam and preparing a Section 45X and ITC qualified optimized inverter with a U.S. partner. It is expanding partner relationships internationally, particularly in EMEA and Australia, and thinning inventory to improve cash. The company raised $15.0 million gross in a February 2026 registered direct offering and signed a $10.0 million Wells Fargo revolving credit facility maturing March 2029. It also monetized patent rights, receiving $17.8 million total consideration, and is pursuing up to $5.0 million in contingent seller-retained royalties. It aims for sustainable profitability through expense discipline and a clearer path to lower operating losses.

Risks

• History of net losses — Tigo reported net losses of $1.9 million in 2025 and $62.7 million in 2024, and management says there is no guarantee it will achieve or sustain profitability.
• Tariffs and trade restrictions — Tigo incurred $1.5 million of tariff-related costs in the first half of 2026 versus $0.3 million a year earlier, with all products imported to the U.S. subject to tariffs from their manufacturing countries.
• U.S. demand and tax-credit expiration — U.S. sales remained soft after expiration of the residential clean-energy tax credit, and the U.S. optimized inverter partner's operational delays pushed the launch ramp to the fourth quarter of 2026.
• Supply-chain concentration and sole-source suppliers — A significant portion of supply originates in Thailand and China, some suppliers are sole-source, and identifying qualified alternatives with sufficient capacity and technical expertise is described as challenging.

Outlook

Management guided third-quarter 2026 revenue within a range beginning at $24 million, though the full range was not included in the excerpt. It expects volume shipments of the Section 45X and ITC qualified optimized inverter to begin ramping in the fourth quarter of 2026. The company cited the FCC decision to restrict future authorizations of foreign-produced power inverters as strengthening the longer-term rationale for its U.S. manufacturing strategy. Europe's recovery was described as continuing at a more measured pace than anticipated.
