SanDisk's Buyback Math: EPS Expected to Reach $787 by 2030

TL;DR
· According to TMT Breakout's calculations, if SanDisk's mid-term profit margin framework is realized and shares are continuously repurchased at around $1500 each, the CY2030 EPS could approach $700.
· The company has committed to returning 100% of excess free cash flow after reinvestment to shareholders, primarily through stock buybacks.
· This outcome heavily relies on NAND prices, long-term AI customer contracts, cash flow conversion rates, and average buyback prices, and is not a formal guidance from management.

After SanDisk announced its FY2030 mid-term framework on Analyst Day, the market began to calculate the amplification effect that high profit margins and continuous buybacks could have on earnings per share.

According to TMT Breakout's projections, if SanDisk's revenue growth, profit margins, and free cash flow targets are all met, and the related cash is used for buybacks at an average price of about $1500 per share, the CY2030 EPS could mechanically approach $700.

This is not a profit guidance provided by the company, but a valuation model based on multiple optimistic assumptions. The core logic is that demand from AI data centers supports NAND prices and profit margins, long-term customer arrangements enhance revenue visibility, and strong cash flow reduces equity through buybacks, further amplifying EPS.

$700 EPS Relies on More Than Just Profit Growth

TMT Breakout states that the CY2027 buy-side EPS forecast remains above $300. Starting from this level and incorporating SanDisk's FY2030 mid-term framework allows for projections of longer-term earnings per share.

The framework provided by management includes: revenue growth maintaining mid to high double digits, gross margin around 80%, operating margin around 75%, and adjusted free cash flow margin around 50%, with capital expenditures maintained at a mid-single-digit percentage of revenue.

SanDisk expects revenue to maintain mid to high double-digit growth from FY2028 to FY2030, with an average gross margin of around 80%, operating margin of around 75%, and adjusted free cash flow margin of around 50%.

The approximately 80% gross margin aligns with some investors' expectations, but the revenue growth outlook is more optimistic. The report states that the market previously expected revenue growth rates for FY2028, FY2029, and FY2030 to be approximately 20%, -17%, and -28%, respectively, still reflecting significant traditional NAND cycle assumptions.

What truly pushes CY2030 EPS toward $700 is the equity shrinkage brought about by buybacks.

Management has formally committed to returning 100% of excess free cash flow to shareholders after completing business reinvestment and maintaining a debt-free balance sheet, primarily through stock buybacks. TMT Breakout further assumes that this cash will be used for buybacks at an average price of about $1500 per share, resulting in an estimated CY2030 EPS close to $700.

It is important to distinguish that the 100% return of excess free cash flow to shareholders is part of the company's capital allocation policy; the $1500 buyback price and approximately $700 EPS are assumptions from a third-party model, not commitments from management.

Long-Term Contracts Enhance Visibility, But Do Not Eliminate NAND Cycles

Whether this buyback model holds depends primarily on SanDisk's ability to maintain high profit margins and free cash flow over the long term.

Management's outlook on NAND prices is more optimistic than that of some investors, expecting prices to remain stable or rise in 2027, while some market views have predicted a decline of 15% to 20%. This divergence is crucial: if NAND prices enter a downward cycle again, gross margins, free cash flow, and buyback capacity could all come under pressure simultaneously.

Demand visibility mainly comes from AI data center customers and long-term collaboration arrangements. The original text states that SanDisk has established eight NBM customer arrangements, three of which involve major U.S. cloud providers, with the longest contract terms reaching four to five years.

Through these arrangements, about two-thirds of FY2028's capacity has already been booked, and the coverage level for FY2029 may also approach that of FY2028. The report also mentions that some customers have recently continued to increase their demand.

These contracts enhance the visibility of near- to mid-term orders and cash flow, but do not prove that NAND has completely escaped the cycle. Long-term contracts can reduce demand fluctuations, but ultimate profits still depend on contract prices, actual purchase volumes, cost changes, and new supply.

Buybacks Can Amplify EPS and Make the Model More Sensitive to Stock Prices

For a company with an adjusted free cash flow margin target of around 50%, buybacks could become an important variable affecting earnings per share.

When total profits grow, continuous buybacks will further reduce the number of shares outstanding, causing EPS growth to exceed net profit growth. The lower the stock price, the more shares can be repurchased with the same amount of cash, making the EPS amplification effect more pronounced.

Under different buyback price and valuation assumptions, the differences in SanDisk's CY2030 EPS calculations are significant; the extreme scenario of continuous buybacks at $1500 per share corresponds to approximately $787 EPS, not the company's target.

However, this mechanism also works in reverse. If SanDisk's stock price is significantly higher than the model's assumed $1500 per share, the number of shares that can be repurchased with the same amount will decrease, and CY2030 EPS will also fall below the mechanical calculation results.

Free cash flow itself also carries uncertainties. If NAND prices fall in the future, profit margins are below targets, or capital expenditures and business reinvestment needs increase, the excess cash available for buybacks will also decrease.

Therefore, an EPS close to $700 should not be regarded as a baseline forecast. Its validity relies on several premises: continued mid to high double-digit revenue growth, gross margins stabilizing around 80%, adjusted free cash flow margins reaching around 50%, excess cash continuously used for buybacks, and actual buyback prices not significantly exceeding model assumptions.

HBF Provides AI Increment, Realization Still Awaits After 2027

In addition to traditional NAND business, SanDisk has also disclosed progress on the next-generation HBF technology.

According to management, HBF has completed tape-out, with samples expected to be available in 2027 and potential mass production starting in 2028. The company positions it as a high-bandwidth storage solution for AI computing, claiming it can provide HBM-level bandwidth at about one-eighth the cost, with capacities reaching 8 to 16 times.

If the relevant performance, cost, and mass production targets are met, HBF could help SanDisk capture higher value in the AI storage market and enhance the motivation for major cloud customers to sign long-term collaboration arrangements.

SanDisk's long-term valuation heavily depends on the EPS path and exit price-to-earnings ratio; $787 EPS belongs to the restrictive scenario of continuous buybacks at $1500 per share, not a baseline forecast.

However, HBF is still in the pre-mass production stage. Sample validation, customer onboarding, manufacturing yield, and scale delivery all carry uncertainties and cannot directly serve as definitive support for the $700 EPS calculation.

What truly changed on SanDisk's Analyst Day was the market's perception of the duration of this NAND boom and the use of cash flow. The high profit margin framework, customer collaboration arrangements, and buyback commitments provided by management collectively offer a more optimistic valuation path than traditional cycle models.

However, TMT Breakout also acknowledges that the most challenging question for the market currently remains: can this cycle extend beyond 2028? The close to $700 CY2030 EPS showcases the upper limit under optimistic scenarios, but achieving it still faces multiple hurdles including NAND prices, profit margins, buyback prices, and execution capabilities.
