Foundations and Early Growth
The company was established on May 28, 1853, originally known as the Aetna Life Insurance Company. Founded by Eliphalet Adams Bulkeley, the firm experienced rapid financial growth during its early decades. By 1867, the company's income had surged from $78,000 in 1861 to over $5.1 million, prompting a move to its third home office located at 670 Main Street in Hartford.
As the business expanded, so did its financial foundation. In 1878, Aetna increased its capitalization from $150,000 to $750,000, signaling its growing stability and influence within the insurance sector.

Expansion and Modernization
The 20th century brought significant changes to Aetna's service offerings and geographic reach. In 1924, the company expanded its presence by selling insurance in Maryland. Throughout the following decades, Aetna transitioned from a traditional life insurance provider toward a leader in health care management.
A pivotal moment occurred in 1998 when Aetna acquired NYLCare Health Plans from the New York Life Insurance Company. This $1.05 billion acquisition was a transformative move that added 2.2 million members to its roster, significantly bolstering its position in the health insurance market.

Diversification of Services
In the early 2000s, Aetna began to diversify its product lines beyond standard health and life insurance. In 2008, the company entered the pet insurance market by offering coverage through Pets Best Insurance Services.

The CVS Health Era
The most significant recent shift in Aetna's corporate structure occurred in late 2018. On November 28, 2018, CVS Health completed its acquisition of Aetna. This $69 billion merger resulted in Aetna being delisted from the New York Stock Exchange (NYSE), where it had previously traded under the ticker symbol AET.
Under the CVS Health umbrella, Aetna continues to operate through various specialized subsidiaries, including:
- Aetna Better Health
- Aetna International
- Meritain Health
- First Health PPO Network
- Active Health Management

The company maintains a significant physical presence across the United States, with various offices serving different regions, such as those in Nebraska and North Dakota.
