Our RUPS business primarily sells pressure-treated railroad ties to the railroad industry in the United States and Canada and treated utility poles to utility markets in the United States and Australia. Railroad products and services include procuring and treating items such as crossties, switch ties and various types of lumber used for railroad bridges and crossings. Utility products include the pressure treatment of transmission and distribution poles for electric and telephone utilities. In addition, we provide untreated wood products and rail joint bars, which are steel bars used to join rails together for railroads, to the railroad markets and inspection services to the utility markets.
We believe our North American utility pole business is the second largest supplier of utility poles in the United States, and we believe our Australian utility pole business is the largest supplier of utility poles in Australia. Our North American utility pole business serves eight of the top ten utilities, based on customer base and revenue, in the United States. Utility poles are produced mainly from pine species in the United States and eucalyptus species in Australia. Most of these poles are purchased from large timber owners and individual landowners and shipped to one of our pole-peeling facilities. In North America and Australia, in addition to utility poles, we market pilings for marine applications and smaller poles to the agricultural landscape and vineyard markets.

Behind the comparison

Sources and methodology

Price return uses split-adjusted daily closes and excludes dividends. Both stocks start on the first shared trading day within the selected window. Unavailable metrics leave gaps.

Financials use SEC canonical statements available by the displayed cutoff, retaining each company's fiscal period end. Annual and quarterly amounts are shown separately. P/E is unavailable when earnings do not support a positive ratio.

Business overlap uses industry tags from annual filings released in 2025. Each core activity receives full weight; each material activity receives one quarter of that weight. Rarer industries carry more weight. We sum the smaller exposure for each shared activity and divide it by the sum of the larger exposure for every activity in either company. This measures business overlap, rather than price correlation or expected returns.

Search eligibility requires distinct issuers, a shared core category and at least 20% weighted overlap, supported by industry or sector evidence and specific business activities. Broad classifications require stronger overlap within the same sector. Comparisons also need at least 252 shared price observations within two years, recent trading and a common sourced revenue or net-income trend. Missing P/E or gross margin alone does not exclude a comparison. The eligibility snapshot refreshes daily. Related comparisons use a separate, stricter peer rule; their ten-peer discovery limit does not limit search eligibility. Other stock pairs remain available in the comparison tool.

Statements available through 2026-10-29. Industry snapshot: 2025-12-31 · 5,721 classified issuers.
