$27 Billion in Buybacks: 3 Stocks Betting Their Strong Runs Aren’t Over

Several industry giants that have seen impressive share price performance in 2026 recently made big-time buyback announcements. Share repurchases can do more than reduce share counts—they can also signal that management sees enough cash-flow strength and balance-sheet flexibility to keep returning capital after a strong run.

Three top firms have added $27 billion in buyback capacity, indicating confidence in their outlooks and cash generation. This includes a $14 billion authorization from one of the best-performing stocks of 2026, which has cemented itself as a critical player in AI infrastructure.

SanDisk Signals Continued Confidence After Hallmark Run in 2026

The insatiable demand for NAND flash solid-state drives (SSDs) from AI customers has led to huge revenue increases and margin expansion at SanDisk (NASDAQ: SNDK). Notably, SanDisk’s revenue rose 372% year-over-year (YOY) last quarter, while its adjusted gross margin increased more than 5,800 basis points to just under 85%.

Aside from this incredible financial performance, the company also made one of the most notable buyback announcements within the AI trade over recent months. SanDisk has announced an additional $14 billion share buyback program, bringing its total buyback capacity to $15.5 billion. The company’s capacity is equal to more than 6% of its market capitalization, a sizable figure.

This announcement is particularly notable due to the huge returns SanDisk has generated. The stock is up more than 500% in 2026—making SanDisk the best-performing large-cap stock in the United States. The company noted at its recent Investor Day that it will return 100% of its excess cash to shareholders. As SanDisk does not pay a dividend, this will come through buybacks

In turn, SanDisk is indicating that it plans to spend billions on buybacks even after the astonishing rise in its share price. This signals considerable confidence going forward and can allow the company to add a meaningful tailwind to per-share metrics.

Phillips 66 Profit Soars, Adds $10 Billion in Buyback Capacity

Although not as stunning as SanDisk’s 2026 gain, oil giant Phillips 66 (NYSE: PSX) has also put up an extremely strong performance, up more than 80%. The company generated adjusted earnings of $3.8 billion in its latest quarter, up from just $207 million in Q1.

Notably, margins on refined products are soaring. Disruptions in the Middle East have not only damaged the worldwide supply of crude oil, but also that of refined products like gasoline. This comes as significant refining capacity resides in the Middle East.

In turn, refineries that continue to operate, like those in the United States, benefit from the imbalance of supply and demand. Notably, crack spreads on diesel fuel, which measures the difference between the price of crude and refined diesel, recently moved above $100 for the first time ever.

As Phillip’s profits surge, the company is adding big-time buyback capacity to return capital to shareholders. The company has approved a $10 billion buyback program, equal to more than 10% of its market capitalization.

Given the lack of progress in Iran and U.S. negotiations, industry analysts do not expect the prices of refined products to fall drastically anytime soon. Phillip’s buyback program indicates confidence in its cash flow generation amid this, while refining imbalances could support strong earnings for some time.

MetLife Lifts Buyback Capacity by $3 Billion, Supporting Further Share Count Reductions

MetLife (NYSE: MET) is one of the largest players in the United States insurance industry, with a market capitalization of nearly $60 billion. The stock has also been one of the better performers in its industry during the year, delivering a total return near 20%. Notably, MetLife achieved solid adjusted earnings growth of 15% YOY in its latest report.

Meanwhile, adjusted earnings per share grew considerably faster at 20% YOY. This demonstrates the beneficial effect of MetLife’s share buybacks, which came in at $722 million during the quarter, moderately lowering its share count.

MetLife has since re-upped its buyback capacity, recently announcing a $3 billion incremental authorization. This lifts MetLife’s total buyback capacity to $3.4 billion, equal to more than 5% of its market capitalization. Although its buyback spending has fluctuated considerably over time, MetLife has delivered value to shareholders by steeply dropping its share count. Over the past five years, MetLife’s outstanding shares have fallen by approximately 25%.

MetLife’s latest authorization gives the firm considerable firepower to continue lowering its outstanding shares and adding a tailwind to per-share metrics as it did in Q2.

SanDisk Stands Out as NAND Demand and AI Growth Accelerate

All three companies are signaling confidence through larger buyback authorizations, but Sandisk may offer the most compelling combination of growth and capital returns.

SanDisk isn’t alone in showing continued confidence in its outlook; Wall Street analysts are doing the same. The MarketBeat consensus price target for SanDisk sits just below $2,000, implying more than 20% upside in the shares. Looking ahead, it will be important to monitor how the supply-and-demand imbalance in NAND flash products evolves.

Notably, some analysts expect the NAND Flash market to become slightly oversupplied in the second half of 2027. This could potentially reduce SanDisk’s pricing power. However, a large wave of agentic AI adoption could put the market closer to equilibrium.

Phillips 66 and MetLife offer more mature capital-return stories, but Sandisk’s combination of AI-driven growth, expanding profitability and a commitment to return excess cash could give it the most upside if NAND demand remains strong. Nonetheless, these dynamics are difficult to forecast, making continued monitoring of updates and management commentary key.
