Shares of Corteva (CTVA) appeared to crater on Thursday, plummeting 84% to close at $12.57 from the prior day’s finish of $77.65. However, the dramatic decline didn’t reflect actual losses. Instead, it marked the completion of a spinoff the company had planned for months.

The spinoff created Vylor (VYLR), which now operates as an independent entity controlling Corteva’s seed and seed technology assets. Each shareholder of Corteva automatically received one share of the newly formed Vylor.

Vylor Inc., VYLR

Trading commenced for Vylor on Thursday, with shares ending the day at $68.26. Combined with Corteva’s closing price of $12.57, shareholders held approximately $81 in total value, representing a slight gain compared to Wednesday’s $77.65 close.

The Rationale Behind The Separation

By revenue and profitability, Vylor represents the significantly larger portion of what was previously a unified business. The seed technology operation recorded approximately $10 billion in revenue during 2025, alongside $3 billion in earnings before interest, taxes, depreciation, and amortization.

Meanwhile, the crop protection division—encompassing herbicides and insecticides—that remains under the Corteva banner brought in $7.5 billion in revenue and $1.4 billion in Ebitda during the same period. Historically, the seeds segment has delivered more consistent earnings growth compared to the agricultural chemicals business.

Prior to the separation, Corteva held a market capitalization of roughly $52 billion. The majority of that value now resides with Vylor.

In a recent analyst note, Oppenheimer’s Kristen Owen suggested Corteva appears undervalued at prices below $12. She calculated the stock trading at approximately six to seven times projected Ebitda, a valuation she characterized as a floor. In contrast, Vylor’s first-day trading implied a multiple closer to 15 times Ebitda.

Corporate restructuring isn’t unfamiliar territory for Corteva. The company emerged from DowDuPont in 2019, six years after the Dow and DuPont merger created that entity. Corteva essentially originated as the Dow Agrosciences division, while Vylor traces its roots to the DuPont Pioneer seeds operation, now finally operating independently.

Major Index Rebalancing Triggered By Spinoff

The corporate separation initiated a series of adjustments throughout the S&P Dow Jones Indices. Vylor will take Corteva’s position in the S&P 500 before markets open on October 6. Due to its reduced market capitalization following the split, Corteva moves to the S&P MidCap 400.

When the index transition occurs, Vylor will be classified within the consumer staples sector. Corteva remains categorized in materials.

The S&P 500 gains another new member simultaneously. Twilio (TWLO), presently listed in the MidCap 400, will claim the index position Warner Bros. Discovery vacates when its acquisition by Paramount Skydance concludes on the expected October 6 closing date.

Shares of Twilio climbed 3% in after-hours trading Thursday after the announcement. The communications platform company has seen its stock price more than double year-to-date.

Additional index movements accompany these headline changes. FormFactor advances to the MidCap 400 to occupy Twilio’s former position, Workiva enters the SmallCap 600 replacing FormFactor, and Corteva’s MidCap 400 addition forces Olin down to the SmallCap 600.

Olin, meanwhile, replaces Qorvo, which is being acquired by Skyworks Solutions, another S&P 500 constituent. Index fund managers face a particularly active rebalancing period.
