Vital Farms, the "bullsh*t free" purveyor of pasture-raised eggs and butter, just reported a record-breaking first quarter. Revenue soared 24%, adjusted EBITDA doubled, and gross margin expanded by a staggering 400 basis points. The market cheered, but I believe there's a hidden clue buried in the transcript that even the most seasoned analysts have overlooked – a clue that could signal an even more explosive future for Vital Farms.

It's all about the eggs. Not just the ethically-sourced, sunshine-drenched eggs themselves, but the subtle shift in how Vital Farms is selling them. While distribution gains and increased SKU placement are grabbing headlines, a quieter revolution is happening in pack size. Consumers are increasingly opting for the 18-count carton, a subtle change with profound implications.

On the surface, the shift to 18-count packs seems like a simple response to value-seeking consumers in a high-inflation environment. Larger packs generally offer a lower cost per egg, a compelling proposition for budget-conscious shoppers. But for Vital Farms, the story runs deeper. The 18-count pack is a strategic weapon, subtly reshaping consumer behavior and forging stronger brand loyalty.

Here's why: Every 18-count carton sold eliminates a purchase occasion for the consumer. Instead of buying two 12-count cartons, they're opting for one larger pack, effectively locking themselves into the Vital Farms brand for a longer period. This increased "lock-in" effect translates to greater predictability for Vital Farms, allowing them to more accurately forecast demand and optimize their supply chain.

But it's not just about operational efficiency. The 18-count pack also serves as a proxy for brand loyalty. Consumers willing to commit to a larger pack are signaling their trust in the Vital Farms brand and their willingness to pay a premium for its values. This growing loyalty base is a powerful asset in a competitive market, providing a buffer against price wars and fickle consumer trends.

Here's where the hidden clue comes in. During the earnings call, CFO Thilo Wrede remarked that the 18-count pack growth is an "expression of loyalty." This seemingly innocuous comment carries significant weight. It suggests that Vital Farms is not merely riding the wave of larger pack size adoption; they're actively driving it, leveraging their brand equity and consumer insights to create a virtuous cycle of loyalty and growth.

Unit Volume Growth in Tracked Channels

While Vital Farms doesn't explicitly break out 18-count pack sales, their tracked channel data offers some compelling insights. During the 13 weeks ending December 24th, 2023, Vital Farms' unit volume grew by 1%, while the overall egg category remained flat. This seemingly modest growth masks the impact of the 18-count pack shift.

Imagine, hypothetically, that 20% of Vital Farms' unit sales in that period came from 18-count packs. This means that if consumers had instead purchased 12-count packs, Vital Farms' unit volume would have been approximately 11% higher, significantly outpacing the overall category. This back-of-the-envelope calculation highlights the hidden power of the 18-count pack strategy.

This subtle shift in consumer behavior could be a game-changer for Vital Farms. By driving adoption of larger pack sizes, they're not just increasing sales; they're cultivating a more loyal customer base, one that's less sensitive to price fluctuations and more receptive to brand messaging. This sets the stage for sustained, profitable growth, potentially propelling Vital Farms beyond its ambitious $1 billion revenue target.

Remember, Vital Farms was founded on a simple yet powerful idea: treat hens right, and they'll lay better eggs. Now, they're applying that same principle to their business model, treating their customers right by offering a compelling value proposition that reinforces their core values. It's a win-win scenario, one that could send the stock soaring in the years to come.
