American consumer goods manufacturers are sitting on a problem they built themselves: too much factory. Keychain research shows one in 10 US factories is running more than half-empty.

Manufacturers invested heavily in new production lines between 2018 and 2022. Low interest rates and tax incentives made it cheap to borrow for capital expenditure. Factory builds became straightforward on a spreadsheet. Then Covid-19 arrived.

Disrupted overseas supply chains pushed more brands to seek domestic manufacturing options, accelerating construction further. Manufacturers built for a demand curve that assumed continued CPG spending growth. That growth has not materialized at the rate projected, and now the machines run below their designed throughput.

Those factories made those investments three or four years ago. The machines are just showing up now, but the demand curve has changed, said Oisin Hanrahan, CEO of Keychain, which released its 2026 CPG Intelligence Report this week.

About 15 percent of manufacturers hit revenue growth of 20 percent or more last year. The companies that expanded capacity most are 2.1 times more likely to hit that benchmark. The manufacturers who invested most aggressively are performing better, but the market still has more supply than demand.

What Overcapacity Means for Brands

For brands, particularly smaller ones and startups, the current environment is a genuine opportunity. Manufacturers with unused capacity are more willing to negotiate on minimum order quantities. A brand that might have needed 10,000 units two years ago might now find the same factory willing to take 2,000.

Pricing is also more flexible. Manufacturers who need to keep lines running have more incentive to offer competitive rates. The balance of negotiating power has shifted toward brands in a way it has not for several years.

The dynamic is particularly beneficial for early-stage companies. Hanrahan noted that if manufacturers were running at full capacity, fewer new brands would get made because there simply would not be slot availability.

How Manufacturers Are Responding

Manufacturers are not standing still. Many are looking at software and AI tools to make their existing operations more efficient. Faster sensors on production lines can detect batch variations before they become quality problems. Demand forecasting software helps align production schedules with actual consumer buying patterns.

The lead time for machinery is long. Manufacturers cannot solve their utilization problems by adding more machines. The lever in the short term is operational: getting more out of what they already have. That means better worker training, tighter changeover procedures, and more sophisticated software.

The shift toward software is also a response to broader market changes. Population growth slowdown and the rise of GLP-1 drugs are expected to reshape CPG demand patterns in the medium term. Manufacturers are building flexibility into their operations so they can adapt without rebuilding physical infrastructure.

The Bigger Picture for CPG Strategy

The excess capacity situation is not going to resolve quickly. Changing how factories are utilized takes multiple quarters or years. The decisions manufacturers made during the low-interest-rate period will continue to shape the market for the foreseeable future.

The opportunity is time-limited. Once manufacturers work through their capacity overhang, negotiating dynamics will shift again. Brands that can act now to lock in favorable terms with manufacturers will benefit most.

For marketing teams, the production side story connects to the go-to-market side. Brands with more manufacturing flexibility can experiment more, test new product variations faster, and bring items to market more quickly. That operational agility is a competitive advantage in CPG categories where consumer preferences change rapidly.

The Keychain data is based on a survey of over 1,000 CPG manufacturers conducted in the first quarter of 2026. The findings show a sector at an inflection point. On one hand, the companies with the most modern, efficient production infrastructure are outperforming their peers. On the other hand, the industry as a whole is carrying more capacity than the current market can absorb.

Hanrahan described the situation in practical terms: most factories are running one to one-and-a-half shifts per day. That means the second shift, and often the machinery on it, sits idle for significant portions of the day. A factory running at 70 percent capacity in a prior decade would have been considered underperforming. Today, it is a common baseline across the sector.

The implications for brand strategy go beyond negotiation leverage. When manufacturers have unused capacity, they become more open to co-development arrangements that would have been non-starters in a tight market. A brand with a unique product concept might approach a manufacturer about creating a custom production run that serves both parties' interests. These kinds of collaborations are becoming more common as manufacturers look for ways to fill their unused lines.

For established CPG brands, the current environment creates an opportunity to revisit contract manufacturing arrangements. Many brands locked into multi-year deals with manufacturers during the tight capacity period of 2021 and 2022. Those contracts often include volume commitments and pricing structures that made sense at the time but are now above market. Renegotiating those deals while manufacturers are hungry for volume can yield meaningful cost savings.

The startup angle is particularly interesting because it connects to broader trends in retail and brand formation. Direct-to-consumer brands, artisan food producers, and specialty beverage companies have all faced historical barriers related to minimum order quantities and manufacturing access. The capacity glut removes some of those barriers, which could contribute to another wave of new brand creation in the next two to three years.

Whether that happens depends on broader consumer spending trends. If CPG demand continues to be flat or grows slowly, the capacity overhang will persist. If demand picks up, particularly in categories like beverages and snacks that have seen recent growth, the excess capacity could clear faster than many analysts expect.

One additional factor worth noting is the role of retail consolidation. As large retailers like Walmart and Amazon continue to consolidate shelf space and negotiate harder with CPG suppliers, manufacturers have an increasing incentive to fill their available capacity with whatever brands can make use of it. This creates a two-tier dynamic in the market: big brands with established relationships get preferential treatment on scheduling, while smaller brands and new entrants get whatever capacity is left over after the major contracts are fulfilled.

The net result is a market that is simultaneously more accessible and more competitive for smaller brands. They can get in the door more easily than in a tight capacity environment, but once inside, they still face significant competition for retail shelf space from established players who have more marketing budget and deeper relationships with retailers.
