A decade ago, U.S suppliers ruled North America. Seven of the top 10 suppliers and 20 of the top 25 were based in the United States. The largest supplier then was Delphi Automotive Systems Corp., with sales of $20.64 billion.
Now Canadian supplier Magna International Inc. reigns as No. 1 for the second consecutive year, even though its sales fell 16.0 percent to $11.42 billion. Delphi Corp. is again No. 2, although its North American sales last year fell 35.8 percent to $7.59 billion.
Rising sales pushed two foreign suppliers into the top 25: Toyota Boshoku America Corp. of Japan and Benteler Automotive Corp. of Germany.
But for most large suppliers, North America was a tough market in 2008. Automakers slashed orders as vehicle sales plunged. Tight credit and high summer fuel prices also hurt.
Of the top 25 suppliers, 19 had lower sales. Eight of those were foreign companies and 11 were based in the United States.
Those with lower sales include Robert Bosch LLC, Denso International America Inc., Lear Corp., Visteon Corp. and American Axle & Manufacturing Holdings Inc.
In absolute dollars, Delphi's sales decline of $4.23 billion was the year's largest. During more than three years in Chapter 11 reorganization, Delphi's sales fell steadily as it sold assets.
The largest sales increase was Toyota Boshoku's $316 million gain, to $2.33 billion.
In percentage terms, Freescale Semi-conductor Inc. had the largest sales gain: a 64.5 percent rise to an estimated $628 million. That was enough to push it to No. 62 on the list of the top 150, from No. 118 last year.
Wescast Industries Inc. had the largest percentage drop among companies that stayed on the list. Its sales fell 54.9 percent to $142 million. That put it at No. 149, from No. 129 last year.
Overall, North American sales for the top 25 suppliers dropped 18.3 percent to $91.22 billion. Combined, the suppliers on the top 150 list posted a sales decline of 16.0 percent, to $162.20 billion.
