Background

CMT Highway manufactured dowel baskets and wire products for road construction; Logan Contractors Supply distributed these materials to general contractors. From 2018 to 2021, the parties maintained a profitable five-year relationship encompassing over 300 purchase orders and generating more than $10 million in revenue for CMT. Logan Contractors was CMT’s largest customer, accounting for up to 45 percent of its annual dowel basket production.

Beginning in 2021, COVID-19-induced supply chain disruptions caused steel prices to skyrocket and created trucking shortages. CMT began missing delivery dates in June 2021. After Logan Contractors sought to discuss remedies, CMT responded in late October 2021 with an ultimatum: accept substantial price increases on existing orders or end the business relationship. Logan Contractors’ legal counsel rejected the demand and declared CMT in breach. Logan Contractors then solicited bids from alternative manufacturers and purchased substitute goods from CMC Paving Solutions and American Highway, incurring $1,529,264.57 in additional costs compared to the original contract price—nearly five times CMT’s demanded increase of $310,082.08.

The Court’s Holding

The Iowa Supreme Court affirmed the district court’s judgment that Logan Contractors properly mitigated damages by purchasing substitute goods from alternative suppliers at market rates. The court held that when a buyer elects to cover under Iowa Code section 554.2712 following a seller’s breach, the buyer is not required to accept the breaching seller’s higher-priced offer—even if that offer is the lowest-cost alternative available. This principle applies because covering is not mandatory, and nothing in the statute obligates an aggrieved buyer to continue dealing with a breaching seller.

The court distinguished between the statutory cover remedy and the common law duty to mitigate damages. CMT’s reliance on Restatement (Second) of Contracts section 350 (which recognizes a breaching seller’s offer as a potentially suitable alternative) addresses mitigation, not cover itself. The burden is on the breaching seller to prove inadequate mitigation. Reasonableness in cover is measured by whether the buyer acted in good faith and obtained goods at market rates at the time of purchase, not whether it chose the absolute cheapest option in hindsight. The court found substantial evidence supported the district court’s conclusion that Logan Contractors reasonably covered because: (1) CMT had demonstrated delivery and production problems before the breach; (2) CMT’s ultimatum destroyed confidence in the commercial relationship; (3) Logan Contractors solicited multiple bids; and (4) substitute goods were purchased at or slightly below prevailing market rates amid pandemic-driven supply chain disruptions.

Key Takeaways

  • A buyer who covers after a seller’s breach need not accept the breaching seller’s higher-priced offer, even if lower than alternatives, because covering is an optional remedy and buyers need not continue dealing with untrustworthy sellers.
  • Cover reasonableness is judged by the buyer’s good faith and the market conditions at the time of purchase, not by hindsight comparison to the cheapest available option.
  • A breaching seller’s prior reliability problems and loss-of-trust-destroying conduct are legitimate factors supporting a buyer’s decision to source products from alternative suppliers.
  • Soliciting multiple competitive bids and purchasing at or near market rate constitute evidence of reasonable cover, even if different suppliers are used for different projects.

Why It Matters

This decision clarifies buyer protections in volatile commodity markets and disrupted supply chains. It prevents breaching sellers from forcing aggrieved buyers to continue the commercial relationship as a condition of recovering damages, and it protects buyers from unfair damage reductions merely because a breaching seller offers a lower price as damage mitigation. By establishing that reasonableness is judged at the time of transaction—considering the buyer’s justified loss of confidence and prevailing market conditions—the court provides practical guidance for parties navigating pandemic-era supply disruptions and sudden cost escalations.

The holding is significant for buyers in industries dependent on commodity supplies subject to price volatility. It confirms that buyers need not gamble on the reliability of a seller who has already demonstrated willingness to breach, hold shipments hostage, and demand unilateral price increases. This protects the legitimate interest in sourcing from reliable vendors at competitive market rates without facing reduced damages awards simply because the original breaching seller later offered a lower price.
