Advanced Medical Optics (AMO)

Advanced Medical Optics, universally known by its ticker symbol AMO, was a global leader in ophthalmic surgical devices and eye care products. Spun off from its parent company, Allergan, in 2002, AMO quickly established itself as a major player in two key areas: cataract and refractive surgery. For cataract patients, it provided the artificial lenses (intraocular lenses or IOLs) and the equipment surgeons used to implant them. For those seeking freedom from glasses, its laser systems were at the forefront of the LASIK surgery boom. The company operated with a classic “razor-and-blades” model, selling high-tech surgical machines and then supplying the high-margin, single-use products needed for each procedure. This created a recurring revenue stream and a sticky customer base of surgeons trained on its equipment. In 2009, AMO's journey as an independent public company concluded when it was acquired by Abbott Laboratories for approximately $2.8 billion.

A Value Investing Case Study

The story of AMO is more than just corporate history; it's a fantastic real-world lesson for any student of Value investing. It encapsulates several key themes that legendary investors look for: a durable business model, a “special situation” birth, and an eventual closing of the gap between market price and Intrinsic value.

The Business: More Than Meets the Eye

At its core, AMO was in the business of sight—a non-discretionary, essential human need. This immediately gives it a defensive quality. People will postpone buying a new car, but they generally won't postpone a necessary eye surgery. This resilience is the first sign of a potentially powerful investment. The company's strength was built on a formidable economic Moat, a term popularized by Warren Buffett to describe a company's sustainable competitive advantage. AMO's moat had several layers:

A "Special Situation" Opportunity

AMO was born as a Spin-off, a type of corporate event that often creates mispriced investment opportunities. As famed investor Joel Greenblatt detailed in his book You Can Be a Stock Market Genius, spin-offs are frequently neglected by the market. The parent company's institutional shareholders might sell their new, smaller shares indiscriminately, not because the business is bad, but because it's too small for their portfolio or doesn't fit their investment mandate. This can temporarily depress the stock price, allowing diligent investors to acquire shares in a great business at a fair price. AMO was a classic example—a focused, high-quality business set free from a larger, more diversified parent.

The Munger Test: Is It In Your Circle?

While AMO's business was strong, it was also technically complex. This brings us to a crucial concept from Charlie Munger: the Circle of competence. Munger advises investors to stick to businesses they can genuinely understand. To properly analyze AMO, an investor couldn't just look at the financial statements. They would have needed to dig deeper and ask critical questions:

Investing in a company like AMO without understanding these drivers would be speculating, not investing. It serves as a potent reminder to know the boundaries of your own knowledge.

The Final Chapter: Acquisition

The ultimate validation for value investors in AMO came in 2009. Abbott Laboratories, a healthcare giant, announced its intention to acquire the company in an all-cash Tender offer. The deal valued AMO at $22 per share, a massive 139% premium to its closing price on the last trading day before rumors of the deal surfaced. This event perfectly illustrates the value investor's endgame. The market, for a time, failed to appreciate the durability of AMO's moat and its consistent cash-generating power. A strategic buyer like Abbott, however, saw the long-term value and was willing to pay a premium for it, delivering a fantastic return to shareholders who had bought in when the company was out of favor. The story didn't even end there; in 2017, Abbott sold the division, now called Abbott Medical Optics, to Johnson & Johnson for $4.3 billion, where it forms the core of Johnson & Johnson Vision today, underscoring the enduring value of the original business.
