Aston Martin Slumps 10% After Cutting 2025 Volumes; YTD Down Nearly 30% as US Tariff Quota Sparks Uncertainty

Shares of Aston Martin (LSE: AML) plunged as much as 10% on Monday after the luxury carmaker warned investors that a worsening tariff environment has knocked the company's near-term outlook.

The company trimmed its volume outlook for 2025, now forecasting wholesale deliveries down a "mid‑high single digit percentage" from last year's 6,030 units, and said it no longer expects to generate positive free cash flow in the second half of the year. Management has kicked off an immediate review of costs and capital spending.

Analysts compiled by Aston Martin had pencilled in an EBIT loss of about £110 million ($148 million). The stock was trading lower through the London morning, having already given up much of its gains for the year - the share price is down roughly 30% year-to-date.

Tariffs are at the heart of the pain. Aston Martin flagged uncertainty stemming from new U.S. tariff policy under U.S. President Donald Trump and a quota mechanism tied to the U.S.-U.K. agreement reached in May. That deal limits duties on 100,000 British-made cars a year to 10%, but the quota adds layers of forecasting difficulty.

Company commentary said the quota mechanism "adds a further degree of complexity and limits the Group's ability to accurately forecast for this financial year end and, potentially, quarterly from 2026 onwards." Supply-chain strains and tweaks to China's ultra-luxury car taxes also made the list.

Aston Martin stressed it is in talks with both the White House and U.K. government to try to clarify the situation, and urged British policymakers to step up support for small-volume manufacturers that provide local jobs and feed the wider auto supply chain.

The auto sector is unusually exposed to tariff shocks because parts and assembly are spread across continents. For a niche marque that counts Bond cameos on its resume, swings in cross‑border trade policy translate quickly into balance-sheet pain.

Short, sharp, and messy: volumes trimmed, H2 cash flow pushed out, and a capex review launched. The near-term picture just got noisier - and the market's reaction was immediate.

Shares are down almost 30% year-to-date. What's next for Aston Martin when quotas and tariffs start clashing with limited production runs?
