Sunrun RUN
Sunrun's Subscriber metric is fabricated — inflated ~20% above EIA filings — letting it overclaim ~$205M in IRS tax credits and prop up a fictitious valuation; Muddy Waters remains short.
Thesis
Muddy Waters reiterates its short on Sunrun after the company's response to MW's prior report failed to reconcile a persistent ~5-quarter gap between its 'Subscriber' metric and the subscription customers Sunrun reports to the U.S. EIA. MW dismantles all three of Sunrun's excuses (Permission-to-Operate lag, billing lag, and pre-pay timing), citing EIA Form 861-M instructions that require accounting-standard reporting regardless of billing collection. A simple PTO-lag model implies an ~8,000 Subscriber gap, yet the actual cumulative delta grew to 52,394 by Q1 2023. A second balance-sheet test shows Gross Solar Asset additions consistently below what reported Subscriber additions imply (overstated by up to 64%). MW concludes Sunrun overclaimed ITCs on ~14,390 nonexistent 2022 systems, equating to ~$205 million of inflated tax-credit claims, and labels Sunrun a 'preeminent' green grift.
SCQA
Sunrun is the largest U.S. residential solar installer, valuing itself for investors on a 'Subscriber' metric and monetizing federal Investment Tax Credits via tax-equity partnership flips on those installed systems.
Sunrun's reported Subscribers run roughly 20% above the subscription customers it files with the EIA, and the gap widens every quarter — none of Sunrun's three excuses (PTO lag, billing lag, pre-pay) survive a simple model or the EIA's own instructions.
Sunrun should disclose, for each quarter since FY 2021, both the number of Subscribers that generated GAAP revenue and the number of Subscribers for which it claimed or effectively sold ITCs.
If Subscribers are inflated as MW shows, then in 2022 alone Sunrun claimed ITCs and tax benefits on ~14,390 nonexistent systems, equating to roughly $205 million of inflated tax-credit claims that should reverse.
The three reasons
- 1
Sunrun's Subscriber count runs ~20% above EIA filings — gap grows every quarter, not consistent with PTO lag excuse
- 2
Balance-sheet test: Gross Solar Asset additions far below what reported Subscriber additions imply
- 3
2022 ITC sales imply ~99,256 systems vs 99,497 Subscribers reported — ~$205M of inflated tax credit claims
Primary demands
- Sunrun should disclose, for each quarter since FY 2021, the number of Subscribers that generated GAAP revenue in that quarter
- Sunrun should disclose the number of Subscribers for which it claimed/effectively sold ITCs each quarter

Notes
Short follow-up note (4 pages of content + 1 page disclaimer) rebutting Sunrun's response to a prior Muddy Waters short presentation. Format is a Word-style memo with embedded screenshots/tables, not a slide deck. Carson Block credited as Director of Research on cover. Quotes Sunrun's response and EIA Form 861-M instructions verbatim to contradict management. Two analytical tests: (a) PTO-lag model showing gap should be constant ~8,000 but is growing; (b) balance-sheet test comparing implied vs actual Gross Solar Asset additions. Closing line frames Sunrun as a 'preeminent' example of 'great, green grifts that partly define our investing epoch.'
