Stem (STEM) Q1 2026 Earnings Transcript

Stem reported Q1 revenue of $29 million, down 11% year over year due to no battery hardware resales, but delivered a record 52% non-GAAP gross margin and $2 million of adjusted EBITDA, its fourth straight positive quarter. Core software, services, and edge hardware revenue rose 4%, PowerTrack software revenue grew 16%, and utility-scale bookings more than doubled quarter over quarter, supporting reaffirmed full-year guidance for $140 million to $190 million of revenue and $10 million to $15 million of adjusted EBITDA. The company also highlighted AI adoption, the raicoon acquisition, and PowerTrack Sage as strategic growth drivers.

Analysis

This quarter is less about the headline revenue miss and more about the probability distribution of the next two quarters: STEM is proving it can de-risk the equity story by converting the business into a higher-quality recurring software platform while preserving optionality on hardware. The key second-order effect is that the mix shift is now so favorable that even modest software growth can produce visible EBITDA leverage, which should force incremental buyers to re-rate the name if they believe the company can keep spending discipline intact through the rest of 2026.

The more interesting signal is not the current quarter; it is the pipeline quality implied by utility-scale bookings and the new ecosystem moves. If EMS and Sage deepen platform stickiness, then raicoon is less a bolt-on and more a churn-reduction tool that raises switching costs and broadens wallet share. That matters because the market tends to underwrite these names as commodity solar software vendors; in reality, the emerging model is closer to an operating system for distributed energy assets, where one successful land-and-expand deployment can create a multi-year revenue stream.

The main bear case is execution timing. Hardware resales remain an earnings bridge, not a durable engine, so any slippage in second-half conversion would expose the fact that operating cash flow is still dependent on working-capital release rather than pure self-funded growth. The other hidden risk is that utility-scale wins look impressive in bookings but can stretch conversion timelines, so the stock could stall for months unless management shows clean sequential ARR and backlog conversion by Q2/Q3. Consensus is likely underestimating how quickly margin expansion can happen; it may also be overestimating how linear the cash inflection will be.

Key Decisions for Investors

• Initiate a tactical long in STEM over the next 1-2 weeks on any post-earnings fade; target a 3-6 month horizon with a favorable 2:1 upside/downside if Q2 shows backlog-to-revenue conversion and ARR progression.
• Use a call spread in STEM (e.g., 6-9 month tenor, 20-30% upside strike gap) to express the view that the market is underpricing margin durability while capping downside if hardware timing slips.
• Pair trade: long STEM / short a higher-beta clean-tech hardware name with weaker recurring revenue quality over 3-6 months; thesis is recurring software monetization should outperform pure project-cycle exposure.
• If holding STEM common, set a hard review point after Q2 results: exit or trim if operating cash flow remains negative and utility-scale bookings do not begin converting into visible revenue, because the stock’s multiple expansion depends on proof, not promises.
• For more conservative exposure, wait for confirmation of sequential ARR growth and a second positive EBITDA quarter before adding; that reduces the risk of buying into a narrative rebound before cash conversion is validated.
