Steel pipe maker TMK said Friday that first-half net profit reached $258 million, up from $67 million last year.
TMK provided a mixed outlook for the rest of the year, with seasonal weakness in the current quarter seen to be followed by fourth-quarter recovery.
"A stronger operating performance expected in the fourth quarter of 2011 should largely offset the negative impact of the preceding quarter," the company said. First-half earnings before interest, taxes, depreciation and amortization reached $625 million, up from $415 million. Revenue in the period was $3.55 billion, up from $2.57 billion.
