The giant natural-gas pipeline company Williams Cos. is buying up the portion of subsidiary Williams Partners that it doesn't already own in a $13.8 billion all-stock deal.

The deal will provide tax benefits to Williams, but some of the partnership's investors could be hit with an unexpected tax bill when they exchange their partnership interests for company shares.

Following in the wake of Kinder Morgan Inc.'s $44 billion consolidation with its pipeline partnerships last year, the Williams deal confirms that some of the energy industry's biggest infrastructure companies are turning away from the tax-advantaged partnership structure, which has been hugely popular with individual investors.

Master limited partnerships aren't subject to income taxes at the corporate level and pay hefty cash distributions to limited partners, which are usually untaxed unless investors sell the units. This type of merger triggers a forced sale and thus a tax bill.

The amount investors will owe can vary widely, depending on when they bought their shares and other factors. Williams hasn't estimated what investors will owe but that amount will likely be somewhat offset by the premium they will receive, which is about 14.5% over the price the partnership units have traded at recently.

Under the deal, Williams Cos. agreed to swap 1.115 shares for each unit of Williams Partners. In the aggregate, Williams will issue 275.4 million shares, which is about 27% of the total shares of the combined company.

Shares of Williams Partners surged 22% to $57.93 after the deal was announced while shares of Williams Cos. rose 6% to $53.07.

Energy companies have used the partnership structure to raise billions of dollars in the last few years. But the structure can be complex and some partnerships end up being squeezed by large payments they make to the sponsoring company. The payments are meant to encourage the company's management to keep paying out more to investors, but can become a financial burden on the partnership as it tries to grow, making it difficult to raise capital.

So some analysts have been expecting more simplification deals, and they say the Williams merger likely won't be the last. Last week, a smaller midstream company, Crestwood Equity Partners LP, unveiled a $3.5 billion merger to simplify its structure by taking a master-limited partnership back in house.

"If you need to be more competitive, you need to be focused on lowering cost of capital," said Raymond James energy analyst Darren Horowitz. Williams is "thinking this is the right thing to do for the next 10 to 15 years. And I agree."

After the Williams deal closes, likely in the third quarter, the combined company will be one of the largest energy infrastructure companies. Executives at the company, which is based in Tulsa, Okla., said it would be more efficient and better positioned to grow, and will be better able to keep increasing its dividend by 10% to 15% a year through 2020.

"This strategic transaction will provide immediate benefits to Williams and Williams Partners investors," said Chief Executive Alan Armstrong.

By buying its partnership's assets, Williams can reset the clock on depreciation of assets, something that will translate into $2 billion in tax savings over 15 years, the company said. Becoming a regular corporation also opens the door to more resilient institutional investors who are typically shut out from the tax advantages partnerships offer.

In February, Williams completed the merger of two master limited partnerships it controls--William Partners and Access Midstream Partners--into one giant natural-gas pipeline system under the Williams Partners name. The company has sought to increase its presence in shale formations where drillers are using new technologies to produce more oil and natural gas.
