WILMINGTON, Del.-- DuPont Co. repelled a push by Nelson Peltz and his firm to join its board, a signal victory for the industrial giant in a battle that tested the limits of a wave of investor activism.

In a close vote Wednesday, DuPont's shareholders re-elected all of the company's sitting directors, rejecting Mr. Peltz's contention that his firm, Trian Fund Management LP, needed to be on the board to juice profits at the 212-year-old producer of Kevlar fibers and Pioneer corn seeds. Trian had sought four of DuPont's 12 board seats--including one for Mr. Peltz, its chief executive--and said the company should slash corporate expenses, better scrutinize spending on research, and consider breaking itself up.

The battle stood out amid recent activist campaigns, in part because DuPont seemed an unlikely target. With a market value of nearly $68 billion, it is one of the biggest companies to ever face such a proxy battle, and by some measures it had performed well under Chief Executive Ellen Kullman, with its shares outgaining the market even before Trian's initial stake became public nearly two years ago.

Ultimately, some investors said they voted for DuPont because they felt Ms. Kullman--who spent much of this year crisscrossing the country to woo shareholders--was herself making investor-friendly moves. And some credited Trian with raising the pressure on her.

"The company, as a result of this, is a little bit stronger, better, more focused," said Kevin Walkush, an analyst with Jensen Investment Management. The Oregon-based fund voted its 1.87 million DuPont shares for management's nominees because of concerns that Trian's focus was too short-term, but Mr. Walkush said Trian forced DuPont's leaders to "sharpen their pencils and really articulate what they're saying and doing."

The outcome is a narrow victory not only for DuPont and Ms. Kullman but also for others in corporate America who are concerned that activist investors" influence has grown too strong and that companies have capitulated to their demands too readily. Even as the number of activism campaigns broadly has soared, to 347 last year from 219 in 2009, proxy fights have declined by about 30%, to 92 last year, according to market-data provider FactSet. And even in proxy fights, companies have increasingly reached settlements.

The loss for Trian, one of the most prominent activist-investment firms, could embolden other companies to take on activists in shareholder votes, though it also suggests that the path to victory lies in strong performance and shareholder-friendly moves rather than in defiance alone. Ms. Kullman in the past two years has announced plans to cut costs and buy back billions of dollars of DuPont's own shares, as well as the spinoff of a division that makes titanium dioxide, all moves she said were part of her team's strategic vision.

The outcome "suggests that the institutional investors thought they were getting the benefits from the activist without putting Peltz on the board," said Christopher Davis of Kleinberg, Kaplan, Wolff & Cohen P.C., a lawyer who often works with activists. "Performance and the perception of improved future performance are much better defenses than the hurdles lawyers erect."

Underlining the mixed message, DuPont shares fell 6.8% Wednesday as investors who had bet that Mr. Peltz would win the fight sold off.

The vote was only Trian's second proxy fight after Mr. Peltz and an ally won seats at H.J. Heinz Co. in 2006. A Trian victory would have made DuPont the largest company to ever lose a board seat in a vote, according to FactSet, but instead Trian joins a list of defeated activists such as Jana Partners LLC at Agrium Inc. in 2013 and Starboard Value LP at AOL Inc. in 2012. Still, Trian's investment in DuPont is lucrative at this point.

Mr. Peltz, speaking briefly at DuPont's shareholder meeting, was defiant. He said that no decisions had been made on what to do with Trian's 2.7% stake in DuPont but that Trian would keep watch. Asked if he regretted the multimillion-dollar fight, he said, "I would do it again" and--noting the close vote--he left open the possibility of starting another fight when nominations for DuPont's board open again later this year.

Ms. Kullman, a 27-year veteran of DuPont who has led the company since 2009, received a standing ovation at Wednesday's meeting in Wilmington, Del., after the vote was announced. She called the process an "interesting engagement" and said that even with the win she didn't think any shareholder would take pressure off her performance.

The battle for investor support continued to the final bell, with Trian and DuPont trading punches in television appearances, shareholder letters and press releases while telephoning investors large and small to make their case. The direction of the vote didn't become clear until soon before the shareholder meeting started, when the two sides learned that DuPont had won the votes of its three largest shareholders--Vanguard Group, BlackRock Inc., and State Street Corp.--people familiar with the matter said.

Trian had won support from Fidelity Investments, J.P. Morgan Chase & Co. and Capital Research & Management Co., people close to the matter said. But the three big index-fund companies, as well as Bank of New York Mellon Corp., which also voted for DuPont, together held a combined 18% of the stock, according to S&P Capital IQ.

Individual shareholders, which the people said overwhelmingly voted for DuPont, represented an additional 30% of shares and about half of those shares voted. The index funds and the retail shares together represented close to half the turnout.

The contest forced Ms. Kullman, who is also chairman, to defend DuPont's integration of scientific research into products as diverse as pesticides and solar-panel components, and to address Trian's attacks related to vestiges of its long history, such as a company-owned hotel, theater and country club.

DuPont sought to rally stockholders by arguing that Trian wanted to slash R&D spending and establish a "shadow management" committed to breaking up the company, although Trian said it wanted only more effective use of research dollars and wasn't locked into splitting the company. DuPont agreed to sell the theater in January.

But DuPont also wanted to show that it was receptive to shareholder concerns, people close to it said. With the race looking tight, DuPont in early April deployed its executives and directors to hold even more discussions and meetings with shareholders, they said.

The effort worked for Colin Wong, an analyst with Mawer Investment Management Ltd., a Calgary, Alberta-based firm that owns about 900,000 DuPont shares. He said DuPont contacted his firm a few weeks ago to put board member Lee Thomas and Chief Financial Officer Nick Fanandakis on the phone.

Mr. Wong told them that some of Trian's points, such as a sharper focus on returns on invested capital, were worth considering. Mr. Thomas, one of four directors that Trian tried to oust, listened and provided examples of how DuPont's board measured performance and strategy, Mr. Wong recalls. "We ended up siding with management, given that they have done a lot of the stuff they said they were going to do," Mr. Wong said.
