Tigo Energy 
Q2 2026 Earnings Results
Tigo reported non-GAAP EPS of $0.03 for the quarter ended June 30, 2026, edging past the estimated $-0.00. Revenue came in at $25.41 million, up 5.6% year-over-year but well below the $30.82 million analyst consensus. The company also fell short of its own Q2 guidance range of $30-32 million.
Gross margin contracted to 39.3% from 44.7% in the year-ago period. Management attributed the compression to product mix headwinds from GO ESS batteries and legacy battery products. Adjusted EBITDA dropped to $52,000 from $1.1 million a year earlier, though non-GAAP net income turned positive at $2.5 million.
Cash improved materially: Tigo reduced inventory 34% versus year-end 2025 and ended the quarter with $16.9 million in cash, aided by a revolver draw. Accounts receivable stood at $14.2 million.
Full-Year 2026 Guidance Cut
The most significant development was management's decision to cut 2026 revenue guidance to $100-110 million from the prior range of $130-135 million. That represents a roughly 20% reduction and implies a sharp deceleration in the second half of the year.
Q3 2026 guidance calls for revenue of $24-26 million with adjusted EBITDA between -$1 million and $0.5 million. The company enters Q3 tracking below its original pace.
EG4 Inverter Delay the Key Drag
The primary culprit is a delay in the EG4 optimized inverter launch. Tigo partnered with EG4 to provide IRS 45X and 48E ITC credit-qualified inverter solutions for the U.S. market. The product was expected to ramp earlier in 2026 but is now not expected to contribute meaningfully until Q4, pushing expected revenue recognition into 2027.
On the Q1 2026 earnings call, CEO Zvi Alon called the EG4 partnership a key growth catalyst for 2026. The delay removes that contribution from the current-year outlook and raises execution risk questions around the partnership.
Soft Residential Solar Markets Persist
Tigo operates primarily in residential solar, and demand in both the U.S. and Europe remains sluggish. On the prior earnings call, management noted Germany and the U.K. showed early signs of improvement, but those markets have not yet delivered sustained acceleration. Italy and Czech Republic showed strong year-over-year growth, providing some geographic diversification.
Regulatory Tailwinds Cited
Management pointed to FCC regulatory actions and EU moves against Chinese inverter manufacturers as potential long-term benefits. Tigo's U.S.-manufactured optimizers and "trusted vendor" positioning could win share as foreign competitors face compliance hurdles, though the near-term revenue impact remains unclear.
What Analysts Expect Next
The next earnings report is scheduled for October 27, 2026. Consensus estimates call for Q3 EPS of $0.03 on revenue of $37.81 million, implying a meaningful sequential step-up that will require execution on the delayed EG4 ramp and stabilization in core residential markets.
The next major catalyst is the EG4 inverter ramp in Q4. If that launch proceeds on schedule, Tigo could see a stronger 2027 as the product contributes a full year of sales. If further delays emerge, the bull case weakens considerably.
