Key takeaways

What the filing shows

Oat Mama LLC filed its voluntary Chapter 11 petition on October 26, 2026 in the Western District of Washington, docket 26-13419. The petition lists estimated assets of $100,000 to $500,000, estimated liabilities of $1 million to $10 million and between 1 and 49 creditors. TheStreet, which reviewed the filing, reported the largest single liability as an $825,000 business loan, alongside debts to banks and credit card companies. No motions, hearings or rulings had been recorded when this was written, and the company is still trading: its website and its Amazon and Target storefronts were taking orders.

The revenue line is the striking part. The filing shows $201,766 of sales in 2024, nearly $1.4 million in 2025 and $528,749 in 2026 through October 27. That is a brand that grew almost sevenfold in a year and then saw its run rate fall by more than half. Neither the petition nor the company has said why it filed, and TheStreet called it a developing story. Founder Eliza Larson had earlier pointed to rising costs and supply chain problems as the business's main challenges.

A ten-year brand that had just reached Target

Larson started Oat Mama in Seattle in 2015 after struggling with milk supply as a new mother, baking lactation granola bars in her home kitchen and selling them through her food blog. A Seattle Refined profile in January 2026 described a warehouse team of nine bakers making close to 20,000 bars a month, a place in Target's accelerator programme a few years earlier, and a broker introduction that turned into a Target buyer relationship and shelf space in stores and on Target.com. The range had widened from the signature Lactation Oat Bar to teas, protein powder and pregnancy and postpartum supplements, sold through Amazon and iHerb as well.

That is the standard growth path for a small food or supplement brand: direct and Amazon first, then a national retailer. It is also the path that strains cash hardest, because the retailer order has to be made, packed and shipped months before the retailer pays, and the brand carries returns, promotions and any compliance problem itself.

The lead notice in California

On September 29, 2026, a California organisation called The Living Gallery LLC sent a second supplemental 60-day notice of violation under Proposition 65 to Oat Mama, iHerb, Target and the contract manufacturer YouBar Inc. The notice, filed with the California Attorney General as AG number 2026-04654, alleges that Oat Mama's Mama Power Protein Powder, UPC 8-60011-96983-3, exposed Californian consumers to lead without the required warning, with sales covered as far back as April 15, 2025. It supplements earlier notices dated April 15 and August 6, 2026.

A Prop 65 notice is an allegation by a private enforcer, not a court finding, and nothing public links it to the bankruptcy decision. The notifier says it will sue unless the companies agree to recall or warn on products already sold, warn or reformulate going forward, and pay a civil penalty. For a brand that sells through Target and iHerb, a notice that also names the retailer is the kind of event that can pause purchase orders while lawyers talk, which is why the Amazon dietary supplement policy now asks for lab testing before many supplement listings go live.

So what: the math of growing into a retailer on borrowed money

Put the filing's own numbers side by side. The $825,000 loan is 59% of the brand's best year of sales and more than one and a half years of its 2026 run rate, which works out to about $53,000 a month against roughly $116,000 a month in 2025. Liabilities of at least $1 million sit against assets of at most $500,000, so even at the most favourable ends of both ranges the company owes twice what it owns. Once monthly sales halved, there was no margin left to service the debt from.

The lesson is not that Target was a mistake. It is that a jump from $200,000 to $1.4 million financed by a term loan leaves no room for a soft year, a retailer that slows reorders, or a compliance notice that freezes a hero product. Our Amazon seller cash flow guide walks through how to size that risk before signing.

Worked example with illustrative numbers

These figures are invented to show the method, not Oat Mama's accounts. A snack brand sells $1.4 million a year at a 42% gross margin, so $588,000 of gross profit covers staff, rent, marketing and interest. It borrows $800,000 at 11% to fund a retailer launch, which costs $88,000 a year in interest alone, or 15% of gross profit, before any principal. If sales then fall to $650,000, gross profit drops to $273,000 and interest takes 32% of it.

Add one compliance event: a protein powder that is 20% of sales is pulled while testing and relabelling happen, costing $40,000 in lab fees, labels and destroyed stock, and three months of its revenue. The same brand is now at $540,000 of sales and negative cash. The decision that mattered was made at the start: fund the launch with margin and retailer payment terms, or with a loan that assumes the growth year repeats.

Before you take the big-box order

  • 12-month cash forecast with reorders at half the first order
  • Term debt under 25% of trailing sales
  • Heavy-metal certificate of analysis for every lot
  • Prop 65 label check for California sales
  • No channel above half of total sales

What small food and supplement brands should do

  • Owner: before accepting a national retailer purchase order, build a 12-month cash forecast that assumes reorders at 50% of the first order and payment at 60 to 90 days. Metric: the lowest cash balance in the forecast stays above three months of fixed costs.
  • Finance lead: cap term debt at 25% of trailing 12-month sales, and prefer inventory finance or retailer early-payment programmes over a fixed loan. Metric: interest as a share of gross profit under 10%.
  • Quality lead: get a certificate of analysis for heavy metals on every lot of protein powder and supplements from the manufacturer, and keep sealed retained samples, then compare lead per serving with OEHHA's Proposition 65 limit of 0.5 micrograms a day. Metric: one certificate on file per lot sold in California.
  • Compliance lead: check whether any product needs a Prop 65 warning on the label and on the Amazon detail page, following the Amazon restricted categories rules for supplements. Metric: zero 60-day notices received.
  • Marketplace lead: keep Amazon and the brand's own site growing while the retailer ramps, so one channel's slowdown does not halve the business, and use the Amazon profit calculator to confirm each channel's margin after fees. Metric: no single channel above 50% of sales.

When this does not apply

A brand with no debt that slows down has a profit problem, not an insolvency problem, and a Chapter 11 filing is a chance to restructure, not a closure: Oat Mama is still shipping. Prop 65 applies to sales into California only, so a brand that blocks California orders is outside the notice regime, though lead limits for supplements sold on Amazon still apply. The revenue figures here come from the bankruptcy filing as reported by TheStreet, and the company has not published its own account of why it filed.
