A Strategy of Acquisition

Finding Opportunity in Distribution

In the early 1980s, the U.S. market for industrial gases was dominated by a few major producers: the Linde division of Union Carbide (now Praxair), Air Liquide, Air Products and BOC. These companies accounted for 60 percent of sales, delivering mainly to major users via large bulk shipments or pipeline. Gases supplied in cylinders and small shipments through independent distributors accounted for the remaining sales to hospitals, welding shops and other small-scale users.

Many of the independent distribution companies were founded after World War II by veterans who took advantage of the G.I. Bill to obtain small business loans. By the 1980s, some were eager to cash out and retire. Spurred by $3.5 million in sales in its first year, U.S. Airgas was eager to oblige.

Forming the Right Strategy

As the industry entered a period of consolidation, U.S. Airgas kicked the acquisition machine into gear. The company purchased distributors in a variety of locations and went after secondary markets served by independents, especially those with excellent growth potential. The strategy focused on customer density around a production plant; establishing anchor businesses and then adding on hubs; embracing rural markets; keeping business local; and focusing on the purchase of well-managed companies.

Look for Density

Customer density around a production plant was considered the most important element in determining profitability, due to the short distance that heavy steel cylinders can be shipped before becoming cost-prohibitive.

Anchor and Add On

U.S. Airgas would sometimes pay a premium for an anchor business in order to establish a foothold in a market. Then, it could acquire companies in the surrounding area. This "anchor and add on" strategy creating regional "hubs" around each anchor business.

Embrace Rural Markets

U.S. Airgas favored rural areas. In the big metropolitan areas, the major producers were dominant, surrounded by many small, competitive companies with low profit margins. By contrast, in a place like Bowling Green, Kentucky, Airgas was able to buy a well-established company that was the largest in the area.

Keep it Local

U.S. Airgas had no immediate ambition for a national presence. Acquisitions were opportunistic. Lacking the infrastructure to support business on a national scale, the company kept its operations local.

Buy Well-Managed Companies

McCausland and his partners sought to acquire well-managed companies. Local operational expertise was essential, ensuring both that acquisitions were viable and that they could run without too much involvement from U.S. Airgas. The partners also looked for profitability; for a sales mix weighted toward gases over equipment and supplies; for markets that were not dependent on any one industry; and for a potential of continued employment of key personnel.

Identifying Anchor Companies and Hubs

The acquisition of Oxalloy in January 1983 strengthened the Connecticut hub. In December 1983 came the purchase of Potomac Oxygen in Virginia, creating a second base of operations. In 1984, a Michigan hub came to life after Mid-Michigan Welding Supply, Valley Oxygen and Wolverine Gas Products were all acquired within a three-month period. In 1985, acquisitions in Tennessee and Georgia formed two more hubs.

By becoming part of U.S. Airgas, companies achieved economies of scale, streamlined their operations and gained buying power. In return, U.S. Airgas got personnel with market knowledge, strategic relationships and loyal customers.

Merging with WERCO

By 1986, U.S. Airgas’ sales had grown to over $35 million. The company believed the opportunity existed to roll up the industrial gas distribution industry, but it lacked the necessary capital. An ingenious solution came through a merger with the Welders Engineering Research Company (WERCO).

With annual sales of $68 million, WERCO was a medium-sized manufacturer of welding supplies and related products used in the industrial gas industry. McCausland and WERCO’s owners agreed to combine the two companies through a reverse merger in which WERCO acquired U.S. Airgas, but U.S. Airgas ran the new company, now called Airgas, Inc. The newly formed Airgas was a $100-million company run by WERCO’s chief executive, C. D. L. Perkins, as CEO. McCausland took over a year later.
