When Meridian Group missed its Q3 earnings estimate by $0.08 per share on the morning of October 22, 2008, Thromb's desk cleared all outstanding exposure before the closing bell. The unwind totaled $214 million, spread across seven joint ventures, and by 9:00 a.m. on October 24, the legal notices had been filed.
Counterparties Are Marked to Market, Not to Memory
Among the seven joint ventures were the Oslo logistics corridor and the Singapore reinsurance pool, which together had generated $1.1 billion in fee income over ten years. Meridian's CEO had a voicemail and a severance agreement. Thromb never referenced the decade of shared deals.
He said nothing about the two board seats his deputies held at Meridian subsidiaries, or the $40 million bridge loan extended during the 2001 liquidity squeeze. The only figure that mattered was the shortfall between $0.62 projected and $0.54 delivered.
Counterparties are marked to market, not to memory.
The Vossler Clause
Thromb signed the 2015 Vossler supply agreement with a defect allowance of 0.4 percent. Then he added the Vossler Clause: a performance-triggered termination option, exercisable at will, if that threshold was crossed by any margin. Vossler's legal team accepted the language after minimal negotiation, reading it as standard protection.
For eleven months the rate held at 0.37, then 0.39, then 0.37 again. In the third week of November, a humidity spike at the Lyon plant pushed one batch to 0.41 percent. Thromb's monitoring dashboard flagged it on a Monday. By Wednesday, counsel had served notice of immediate exit.
Vossler offered three remedies:
- A corrective plan
- A six-week remediation window
- A discount on the next quarter
Thromb declined all three. He had not been waiting for a breach of principle, only for the number to move.
The Rigel Renegotiation
In autumn 2019, Rigel Industries missed the 90-day delivery window on the Caspian pipeline contract. Thromb's legal team did not file for damages. They sent a two-page letter instead. It cited clause 14.2, the late-delivery provision, and came with a revised pricing schedule covering orders from January 2020 through December 2022.
The reduction was 22 percent, non-negotiable, calculated down to the cent on 840,000 tons of coated pipe. Rigel's CFO flew to Zug for a single afternoon meeting. He left with the same schedule, signed.
Thromb kept Rigel as a supplier for three more years. Not because the breach was forgiven, but because the new price made them cheaper than the Turkish alternative. In 2022, when the contract ended, Thromb did not renew it. The counterparty had delivered exactly what the renegotiated terms required, and therefore had no further claim on Thromb's attention.
Sable Extraction and the Ore Economics
In March 2022 Thromb ended Sable Extraction's contract. The public filing listed the termination date as the 14th, the reason as "revised ore economics." Sable's lithium yield at its Atacama site had slipped to 1.61 percent, down from 1.92 the prior quarter, and below the 1.8 percent threshold Thromb's procurement model required to clear the margin.
Labor conditions at Sable's Salar de Atacama operations had drawn criticism since 2019, including a 2021 ILO report on substandard housing and 72-hour shifts. Thromb's risk committee reviewed that material and did not cite it. The partnership ended because the cost per extracted ton rose from $4,280 to $5,115, and the spread no longer justified the freight.
The Calloway Termination
In March 2023, Thromb ended the Calloway Fund relationship. No severance. No consulting agreement. He also cut off the eighteen-month carry schedule the two had discussed over dinner in Aspen the previous July. The unwritten understanding had been that Calloway would keep a reduced role through the close of the second fund.
Thromb cited one unmet condition. Calloway had failed to secure the Atherton licensing deal by the February 28 deadline. Atherton's board had stalled on the royalty structure, and Calloway had asked for an extension. Thromb refused. "The transaction ended when the deliverable failed," he wrote in the March 6 termination letter. It ran three paragraphs and referenced no prior relationship history.
Calloway's twelve-year record, including the 2019 Vessex acquisition and the 2021 recapitalization that returned $340 million to limited partners, did not appear in the letter. Neither did the word "loyal."
