Overview

Arbor Drugs was an American regional pharmacy chain headquartered in Troy, Michigan. It became one of the largest drugstore operators in the United States before its acquisition by CVS Corporation in 1998. The company’s principal market was southeastern Michigan, where it developed a particularly strong presence in the Detroit and Ann Arbor areas. The business grew out of Civic Drugs, a store opened by Eugene Applebaum on Michigan Avenue and Greenfield Road in Dearborn in 1963. Applebaum expanded through acquisitions during the 1970s, while Bruno Manni brought experience from establishing a network of Sentry Drug stores. In 1974, their operations were incorporated under the Arbor Drugs name, chosen as a reference to Ann Arbor, Michigan. Unlike many competing drugstore chains that diversified into broader retail categories during the 1970s and 1980s, Arbor concentrated on pharmacy operations. Prescription filling, pharmacy services, and related health products were central to its business model. The chain was an early adopter of computerized prescription processing, introducing the capability in 1979 and later linking store records across its network by 1989. This technology investment supported centralized information management and helped the company scale its pharmacy-focused model. Arbor expanded through both acquisitions and new-store development. Its purchase of 11 former Cunningham Drug locations in 1981 increased the chain to 30 stores. An attempted geographic expansion into the Carolinas did not succeed, and the stores there were subsequently closed. Arbor later concentrated its resources on Michigan, expanding into communities including Ecorse and Hamtramck. During the early 1990s it remodeled a substantial portion of its stores and invested heavily in pharmacy systems. The company became publicly traded on NASDAQ in 1986 under the symbol ARBR. By the mid-1990s it had grown to more than 150 locations, and it acquired the rival M&R chain in 1994. Additional store openings in 1996 and 1997 helped bring its network to more than 200 locations. By 1998, Arbor was described as the eighth-largest regional drugstore chain in the United States, with 207 stores across southeastern Michigan. Pharmacy operations accounted for more than half of company sales, reflecting the focused positioning that distinguished Arbor from more diversified competitors. Arbor also faced significant legal and regulatory difficulties in the 1990s. It was accused of overcharging the Blue Cross and Blue Shield Association on prescription claims and later faced allegations involving the falsification or inflation of Medicaid reimbursement claims. The company reached monetary settlements in both matters; the available historical account also states that the related criminal and civil charges were eventually dropped. CVS Corporation announced its acquisition of Arbor Drugs in February 1998. The transaction was completed approximately two months later and was valued in contemporary reporting at about $1.48 billion. Most Arbor locations were converted to CVS stores, although some were later closed. The Arbor Drugs brand therefore ceased to operate as an independent chain. After the transaction, Eugene Applebaum joined the CVS board and participated in overseeing new-store development in Michigan and Toledo, Ohio.

History

Arbor Drugs developed from a group of independent Michigan drugstores assembled by Eugene Applebaum. Applebaum opened Civic Drugs in Dearborn in 1963 and acquired five additional stores during the 1970s. In 1974, he and Bruno Manni incorporated their operations as Arbor Drugs. Manni had previously founded and established 11 brick-and-mortar Sentry Drug stores. The Arbor name referred to Ann Arbor, Michigan. The company pursued a focused pharmacy strategy at a time when many drugstore competitors were adding broader retail categories. Arbor’s emphasis remained prescription dispensing and pharmacy services. In 1979 it became one of the early drugstore chains to offer computerized prescriptions, and by 1989 its store records were linked. These systems helped the company manage a growing network and reinforced its pharmacy-oriented identity. Acquisitions played a major role in Arbor’s expansion. In 1981, the company acquired 11 former Cunningham Drug locations, bringing its total to 30 stores. It also tested expansion outside Michigan by opening three stores in the Carolinas, but that effort was unsuccessful and the stores were closed. The company subsequently concentrated on southeastern Michigan, including markets such as Ecorse and Hamtramck. Arbor became a public company in 1986, listing on NASDAQ under ARBR. At that point it had 52 stores. In the early 1990s, management remodeled approximately 70 percent of the chain’s stores over a five-year period and invested $10 million in advanced pharmacy systems. The company continued to expand while upgrading its locations and operating infrastructure. The 1990s brought both growth and controversy. Arbor acquired the M&R drugstore chain in 1994 and opened 30 new stores during 1996 and 1997. By 1998 it operated 207 locations throughout southeastern Michigan and was identified as the eighth-largest regional drugstore chain in the United States. Its pharmacy business represented 51 percent of total sales in 1997, illustrating the extent to which prescription services remained central to the company’s model. Arbor was also involved in two major reimbursement disputes. In 1993, it was accused of charging the Blue Cross and Blue Shield Association at least $17 million too much for prescriptions dating from 1988. The parties reportedly settled for $15 million outside court. In 1994, Arbor faced allegations concerning the intentional falsification and inflation of Medicaid reimbursement claims and paid $7 million to the government to settle the matter. The available account says that all related criminal and civil charges were ultimately dropped. CVS Corporation announced its purchase of Arbor Drugs on February 9, 1998. The transaction, reported at approximately $1.48 billion, was completed around two months later. Most Arbor stores were converted to CVS locations, while some were eventually closed. The Arbor Drugs brand disappeared as an independent operating chain. Applebaum later joined the CVS board and was involved in supervising new-store openings in Michigan and Toledo, Ohio.

Products and positioning

  • Pharmacy

    Prescription medicines

The company invested in computerized prescription systems beginning in 1979 and linked store records by 1989, supporting the management of prescriptions across its growing Michigan network.

  • Health products

    Over-the-counter medicines

    Arbor’s retail drugstores carried nonprescription medicines and related health products alongside their pharmacy operations.

  • Retail merchandise
