Berkshire Share Repurchase Slowdown & Price-to-Book Ratios

For years, Berkshire Hathaway deployed substantial portions of its free cash flow into repurchasing its own Class A and Class B shares. However, corporate finance metrics in the Warren Buffett 277 billion cash market crash playbook point to why buybacks have decelerated dramatically as valuations reached multi-decade highs.

While the board previously maintained a rigid rule capping buybacks at 1.2x price-to-book (P/B) ratio, Buffett amended policy to permit repurchases whenever both he and the vice chairs believe the shares trade below conservative estimates of intrinsic value. When Berkshire’s price-to-book ratio climbed toward 1.5x to 1.6x, buyback volume dropped to near-zero.

When Warren Buffett refuses to buy back his own stock—a company whose balance sheet and earnings power he understands more intimately than any external investment—it signals to public markets that overall equity valuations have entered stretched, historically vulnerable territory.
