The company has faced multiple operational challenges including supply-chain issues, supply-shortage problems during peak demand, and accusations of greenwashing in some markets. The brand voice has held up; the financial performance has been more volatile. ## Where Oatly was in 2011 Oatly had been quietly making oat milk in Sweden since the 1990s. The product was technically interesting (better for lactose-intolerant consumers, lower environmental footprint than dairy) but the brand was a niche specialty product mostly invisible outside Scandinavia. The category itself barely existed in the US. Toni Petersson took over as CEO in 2012 and rebranded the company around a deliberately weird, self-aware voice. The packaging copy, instead of describing nutrition or product attributes, talked directly to the customer in casual, self-aware, oat-obsessed tone. The voice was distinctive enough that customers noticed. ## The brand voice Oatly's voice has several distinctive elements that compound across every touchpoint: - **Conversational packaging.** The cartons read like a person talking to you — long copy that's casual, self-aware, sometimes self-deprecating. Every product has different copy. The packaging is the marketing. - **Anti-corporate aesthetic.** Hand-drawn elements, asymmetric layouts, copy that breaks convention. The brand feels like it was made by a person, not a marketing team. - **Coffee-first distribution.** Oatly partnered with specialty coffee shops (Stumptown, Blue Bottle, Intelligentsia in the US) to get baristas using oat milk. Barista evangelism drove consumer adoption. - **Sustained voice across channels.** The packaging voice is the same as the social-media voice is the same as the website voice is the same as the IPO-prospectus voice. The consistency makes the voice feel real. ## What grew Oatly scaled through 2016-2019 in the US through specialty coffee partnerships, then mainstream retail (Whole Foods, eventually broader supermarket distribution). The brand created the modern oat-milk category in the US. Competitors arrived (Califia Farms, Planet Oat, Chobani Oat) but Oatly held the category-defining brand position. Oatly IPO'd on NASDAQ in May 2021 at $10B+ valuation amid significant investor enthusiasm. Post-IPO performance has been harder. The stock lost meaningful value from the IPO peak through 2022-2024. Operational challenges (supply-chain issues during peak demand, capacity expansion overruns, accusations of greenwashing in some markets) have weighed on the company. The brand voice has held up; the financial performance has been more volatile. ## How RGM thinks about brand-voice-as-strategy When clients in CPG ask about brand voice, the Oatly case is the structural example. The conditions: a product that's functionally similar to competitors (oat milks are commodity-similar), a voice that's distinctive enough to be recognizable on a shelf, and sustained consistency across every brand touchpoint including operationally-unusual surfaces like packaging copy. The harder lesson is that brand voice alone can't fix operational challenges. Oatly's IPO-to-post-IPO trajectory shows what happens when brand investment outpaces operational execution. We tell clients that brand voice has to be paired with operational discipline. The voice can carry the brand through challenging market periods, but it can't substitute for actually running the business well. ## Frequently asked questions Did Oatly really invent the oat-milk category in the US? Largely yes — Oatly is widely credited with creating the modern US oat-milk category through specialty-coffee partnerships starting around 2016. Other oat-milk products existed before but Oatly turned it into a mainstream category. Pacific Foods and a few other brands had small oat-milk products but the category was negligible until Oatly's US scale-up. What was the Stumptown shortage? In late 2018 and through 2019, demand for Oatly outstripped the company's US production capacity. Specialty coffee shops (Stumptown, Blue Bottle, others) ran out of Oatly periodically. The supply shortage became its own marketing story — the brand was so popular it couldn't make enough. The shortage problem also reflected real operational challenges Oatly faced scaling production. Why has the stock declined since IPO? Multiple factors. Production capacity expansion in the US ran over budget and produced output below planned levels. The broader oat-milk category became more competitive (Planet Oat, Chobani Oat, Califia Farms, store-brand alternatives). Some investors have raised concerns about greenwashing in some marketing claims. The combination of supply-execution issues and competitive density has produced harder-than-expected financial performance. ### Sources & references - [Oatly investor relations (OTLY)](https://investors.oatly.com/) — SEC filings and quarterly reports. - [Oatly (company site)](https://www.oatly.com/) — Product and brand reference. - [Toni Petersson interviews](https://www.fastcompany.com/) — Trade-press coverage of the brand rebrand era. ## Related [#### All case studies The full case-study library.](/learn/case-studies/)[#### Liquid Death Identity-driven brand in adjacent commodity beverage.](/learn/case-studies/liquid-death-disruptive-positioning/)[#### Beyond Meat Category creation in plant-based CPG with similar IPO trajectory.](/learn/case-studies/beyond-meat-plant-protein/)[#### Mailchimp Distinctive brand voice in commodity-product category.](/learn/case-studies/mailchimp-rebrand-intuit-acquisition/)
