CLSK · CleanSpark, Inc.

The thesis

CleanSpark's Georgia data-center lease is financed and intact, but the shares closed at $7.77 on 26 October 2026, 61.5% below the 52-week high of $20.2, as mining output and earnings estimates fall. The fiscal-year report expected in December settles whether mining cash flow can carry the company until lease revenue starts in late 2027.

The price has broken the $9.50 invalidation level named in the previous note, which was set under the $10.12 close that ended 2025. The note's rating stays at the lowest tier because nothing new has strengthened the lease or the financing since 25 September 2026. The new facts are lower analyst targets, falling estimates and a lower share price.

The shares have fallen from $14.47 on 18 September 2026 to $7.77.

Bullish and bearish views on CleanSpark, Inc.

The bull case on CleanSpark, Inc. (CLSK), in brief: The lease is signed and funded. The bear case: Mining output is falling.

Bull case

• The lease is signed and funded. The 20-year triple-net Sandersville lease carries $6.6 billion of contracted revenue, and the company's 8-K shows the remaining construction cost was financed with notes closed on 25 September 2026. CEO Matt Schultz expects about $330 million of annual net operating income, according to TIKR.
• Analysts still rate it positively. Canaccord Genuity initiated coverage on 22 October 2026 with a Buy rating and a $20 target. Cantor Fitzgerald kept Overweight on 16 October 2026 but cut its target to $19 from $26.
• The tenant is a large credit. Bloomberg identified a Meta subsidiary, Anviran, as tenant on 17 September 2026, with Meta guaranteeing rent. Company filings describe it only as an investment-grade technology company.
• A second lease is possible. Up to 885 megawatts (MW) of Texas capacity is under exclusivity with the same tenant, according to TIKR on 22 October 2026. No lease is signed.
• Selling pressure is extreme and shorts are crowded. The 14-day Relative Strength Index, a 0–100 momentum gauge, read 9.1 on 26 October 2026; readings under 30 are conventionally called oversold. Short interest was 42.81% of the float on 25 September 2026 per Benzinga, so a rebound could be sharp if the lease story regains attention.

Bear case

• Mining output is falling. The company produced 529 bitcoin in September against 593 in August, and average hashrate fell to 36.0 exahashes per second (EH/s) from 38.3 EH/s, per its monthly updates. Monthly updates have ended, so the next production figures come with December results.
• Estimates are being cut. Analysts now expect a fiscal 2027 loss of $1.81 per share against $0.72 three months earlier, and fiscal 2026 revenue of $594 million against $766 million, according to TIKR on 22 October 2026.
• Losses are large. Mining revenue for the nine months to June was $455.6 million against $542.7 million a year earlier, and a $587.2 million bitcoin markdown hit results, per TIKR. Fiscal third-quarter net loss was $239.8 million, per Benzinga on 25 September 2026.
• The lease pays nothing before late 2027. The first data hall is scheduled for Q4 calendar 2027. The notes pay 7.875%, and CleanSpark's completion guarantee leaves the parent exposed to cost shortfalls.
• Targets assume a rich multiple. TIKR calculates Canaccord's $20 target at 8.8 times forward sales against a five-year average of 3.5 times, and the shares traded at 3.9 times at the $8.75 close on 21 October 2026. TIKR's author calls the target overly aggressive.

Price setup

The adjusted daily close on 26 October 2026 was $7.77. The shares are down 35.3% over three months and sit 61.5% below the 52-week high of $20.2.

The 13 October 2026 close of $10.15 is the nearest reference for a recovery. A close back above it would show the decline has stopped; until then the shares trade in a falling range. A close below $6.80 would extend the decline and end this note's case.

Crowding evidence points to forced selling more than to heavy buying. Short interest was 42.81% of the float on 25 September 2026, and the RSI of 9.1 shows few sellers left unsatisfied by price alone. No earnings date falls inside the next 30 days. No SEC filings were reported in the last 30 days.

Catalysts, next 30 days

• No company-dated event falls before 26 November 2026. The company has said it is moving to standard quarterly reporting and has discontinued monthly operational updates.
• ~15 December 2026, est.: fiscal fourth-quarter and full-year results. The first audited read on mining margins, bitcoin fair-value marks and cash burn after the notes.
• No fixed date: a signed Texas lease. It would show Sandersville is repeatable.
• 1 April 2027: first semiannual coupon on the 7.875% notes.
• ~1 October 2027, est.: first Sandersville data hall ready for service, when lease revenue begins.

What would change the view

The case breaks if Sandersville slips past Q4 calendar 2027, or if the parent funds a cost overrun above the $1.8–2.1 billion the company stated on 6 August 2026. It also breaks if the December report shows bitcoin production below September's 529 or holdings below 13,530.

On price, a daily close below $6.80 ends the case. A close above $10.15, the 13 October 2026 close, with production stabilising, would improve it.

What it trades with

CleanSpark moves with bitcoin and with other listed miners. Bloomberg, Benzinga and TIKR coverage tied the 6 October to 9 October 2026 drop to a crypto-stock selloff. Bitcoin held was worth about 40% of a $2.70 billion market capitalisation on 8 October 2026, so bitcoin marks drive reported results.

The Sandersville lease links the shares to AI data-center financing sentiment. The Information reported on 30 September 2026 that data-center debt concessions could stall AI build-outs.
