A few things worth considering with M&A activity:
1. What is the railroad worth? Depends on how the acquirer values it. Could be worth the asset book value or less, especially if they're in money trouble. Could be worth the present value of the future cash flows if they're in good shape. And it could be worth more than that, if the acquirer sees more value in it - if a new owner could somehow double profitability or some similar radical change, the value is higher, especially when the current owner knows about the radical change. A good example of this is EMD - the private equity owners knew Cat could do wonderful things with EMD because Cat has lots of capital and resources, where an independent EMD doesn't. That's why GM sold it for $250m and Cat bought it for $800m. They don't build 4x more locomotives now than 2005, it's just worth more to new owners at Cat.
2. How does M&A happen? CP is publicly held, but that doesn't mean they have to hold a public meeting in the initial phases of the deal. Many times it's very hush-hush. That's why when CSX and NS broke up Conrail, David LeVan had to be called back from vacation - the talks were progressing without him because they were secret. The process usually goes like this: talks, handshake agreement, numbers crunching, approval by board of directors, due dilligence, evaluation by outside firms (law, accounting, banking), announcement. Usually, the union bosses are consulted at some stage (just as they were with the last few rail mergers) and the laywer, bankers, and accountants are brought in. At some point, word is bound to leak but the source stays quiet for fear of retribution. Want a 90 minute lesson on M&A? Watch "Barbarians at the Gate" or "Other Peoples' Money". They're not exact and not completely realistic, but reasonably close. Sometimes leaks happen because one party wants what another party won't give them, and we all find out early.
Does this really mean D&H is for sale? We have no idea. Frankly, with a public corporation, anything is for sale for the right price. It's management's job to maximize shareholder value. If Alpo Dog Food wanted to by UPRR and offered 50% over historic share price highs, it could happen [pending regulatory approval and arrangement of financing] despite being a really illogical idea. Keep in mind, ICG was owned by a chocolate company, BAR was owned by a towel company, and MEC was owned by a filter company.
A little food for thought.
