Bear Case Considerations
A bear case for ARB requires intellectual honesty. This is one of the highest quality businesses on the ASX, with a 50 year track record, no debt, dominant domestic market share and a genuinely wide moat. The bear case is not that ARB is a bad business. It is that the current growth narrative depends heavily on assumptions that may not play out, and that even after a severe de-rating, the risks have not fully resolved.
At the time of writing ARB trades at $17.88, implying a market capitalisation of approximately $1.49 billion. The stock has fallen more than 55% from its peak above $55 in January 2022. The market has already repriced significant risk. The question is whether that repricing is sufficient, or whether the structural headwinds justify further downside.
The US is the thesis and it is unproven at scale
The entire re-rating argument for ARB rests on the US expansion succeeding. The Australian aftermarket business is mature, revenue was down 1.7% in H1 FY26 and has been broadly flat for several years. ARB's 10 year revenue CAGR has moderated from approximately 19% since its 1987 listing to approximately 8% over the past decade. Without the US delivering meaningful earnings growth, ARB is a high-quality but slow growing domestic company, and the question becomes what multiple that deserves.
The ORW/4WP acquisition was made from a business in Chapter 11 bankruptcy. ARB and ORW moved quickly to restructure, closing 5 of the initial 53 stores, transitioning the ERP system and integrating approximately 500 employees, and early results are genuinely encouraging. But 48 stores across only 9 US states is a thin foothold in a country with a truck aftermarket estimated at 10 times the size of Australia's. The store-in-store ARB display rollout is still in early stages, with initial pilot stores in California, Nevada, Colorado, Texas and Florida only now being assessed and expanded. Success in 6 pilot stores does not confirm success across 48 stores, let alone the broader US market.
The American consumer's relationship with truck accessories is structurally different from Australia's. US buyers have historically shopped by category, Warn for winches, Fox for shocks, Method for wheels, rather than doing a full ARB-branded build. ARB's thesis requires changing that behaviour at scale, which is a cultural and marketing challenge as much as a distribution one. There is no guarantee it works on the timeline or at the margins the market may be expecting.
The AUD/THB exchange rate is improving but remains a risk to monitor
One of the biggest drivers of profit compression in FY25 and H1 FY26 was the weakness of the Australian dollar against the Thai Baht. A significant proportion of ARB's products are manufactured in Thailand, so costs are denominated in Thai Baht while revenue is predominantly in Australian dollars. When the Baht strengthens or the AUD weakens, margins compress directly and immediately.
The picture has improved materially since the depths of 2025. The AUD/THB rate has recovered from the 21.0 to 21.5 Baht to the dollar range that prevailed through most of calendar 2025 to approximately 23.4 Baht to the dollar as at May 2026, a roughly 10% improvement in ARB's purchasing power for Thai manufacturing costs. A year ago one Australian dollar bought approximately 21.28 Baht. Today it buys approximately 23.4 Baht. That is a meaningful shift and if sustained represents genuine margin relief heading into 2H FY26 and FY27.
Management has also hedged 2H FY26 Baht exposure at rates described as slightly more favourable than the prior corresponding period, so the near-term earnings impact should be visible in the second half result.
The residual bear case on currency is not the current rate but the volatility risk. The 90 day range has been 21.88 to 23.47, illustrating that the rate can move materially in short periods. ARB has no ability to control the AUD/THB rate and a reversal back toward 21 Baht would immediately re-impose the margin pressure seen in H1 FY26. The structural dependency on Thai manufacturing remains, it is the source of ARB's cost competitiveness, but it also means the company's margins are permanently exposed to a currency pair that most Australian investors do not naturally monitor. The improvement as at May 2026 genuinely weakens this pillar of the bear case, but it should be monitored rather than assumed away.
Discretionary exposure in a prolonged consumer downturn
ARB sells accessories for trucks, discretionary products attached to discretionary vehicle purchases. The business is not recession proof. The only prior year of meaningful negative revenue growth in ARB's listed history was 1991, during an Australian recession, when domestic sales fell 6% and profit declined 73%. Revenue recovered, but the profit sensitivity to volume was severe and illustrative.
The current environment shares some of those characteristics. Australian consumer sentiment remains soft. New vehicle sales of ARB's core platforms, Toyota Hilux, Ford Ranger and Isuzu D-Max, were all down 17% in FY25. H1 FY26 showed the Ford Ranger down 1%, Ford Everest down 9%, LandCruiser 70 Series down 12% and Isuzu D-Max down 13%. When fewer new vehicles enter the fleet, the addressable market for accessories shrinks in the near term and ARB's fitting operations, which are labour-intensive and largely fixed-cost, become underutilised.
A prolonged period of weak new vehicle sales, combined with currency headwinds, could see earnings stagnate for multiple years even if the underlying business quality remains completely intact.
OEM revenue is concentrated and lumpy
OEM sales represent approximately 8% of revenue but declined 38.2% in H1 FY26, worse than management guided at the October 2025 AGM. The explanation is plausible. OEM customers overstocked in 2H FY25, then vehicle sales weakened, so orders dried up. But the episode illustrates that OEM revenue is materially lumpier and harder to forecast than aftermarket sales. A contract with Toyota or Ford is a genuine competitive advantage, but it also creates customer concentration risk. If either relationship changed through a contract not being renewed, a model mix shift or an OEM moving to an alternative supplier, the revenue impact would be immediate and visible in the result.
The fitter technician shortage is a structural operational constraint
ARB explicitly flags in both the FY25 annual report and the H1 FY26 result that fitting operations are impacted by a shortage of fitter technicians. This is not a temporary post-COVID problem. It has persisted across multiple years of reporting. Fitting is central to ARB's retail model as it generates service revenue, ensures products are properly installed on complex modern vehicles and locks customers into the ARB ecosystem. A structural inability to scale fitting capacity caps store throughput regardless of how many stores are opened or how healthy the order book is.
The valuation question after a significant de-rating
ARB historically traded at 25 to 35 times earnings, reflecting genuine quality. The stock has now fallen more than 55% from its 2022 peak, trading at $17.88 with a market cap of approximately $1.49 billion. At approximately 83.5 million shares on issue and annualising H1 FY26 underlying NPAT of $43.2 million, a full year FY26 result of approximately $85 to $95 million seems reasonable if the second half recovers as guided. That implies a forward PE of approximately 16 to 18 times, a significant discount to the historical range.
The bear case on valuation is not that ARB is obviously expensive today. It is that a further miss, a 2H FY26 margin recovery that falls short of guidance or OEM sales weaker than expected, could compress earnings and sentiment simultaneously from a price that already reflects considerable disappointment.
Competitive intensification in the US
Fox Factory Holdings is the most comparable publicly listed US competitor, with approximately $1.4 billion in revenue and an aggressive acquisition strategy spanning FOX shocks, Method Race Wheels, BDS Suspension and truck upfit brands. Fox Factory is better capitalised for the US market and has deep home-ground distribution advantages. The Made in USA narrative, which brands like Addictive Desert Designs use effectively for Jeep and Ford Raptor fitments, resonates with American buyers in ways that ARB's Australian heritage does not automatically replicate.
US tariffs on steel, aluminium and automotive products, flagged explicitly as a headwind by ARB management in FY25, directly increase input costs for products manufactured in Thailand and shipped to the US. If tariffs escalate or become permanent structural policy, they impair the economics of ARB's US business model, which currently relies on Thai-manufactured product shipped to the US rather than local manufacturing.
EVs and the BYD Shark represent a long-term structural question
ARB openly acknowledges in the H1 FY26 report that it is monitoring accessory demand for the BYD Shark. The electric pick-up presents a genuine medium-term uncertainty. ARB's core products including bull bars, suspension lifts, snorkels and long-range fuel tanks were designed for and validated on internal combustion engine 4WDs. Electric pick-ups have different weight distributions, different underbody configurations, no combustion air intake requiring a snorkel and different safety system integration requirements. Accessory attachment rates for new EV entrants are unknown and the customer demographic may differ from ARB's traditional buyer.
This is not an immediate threat as ICE trucks will dominate the relevant vehicle fleet for at least a decade, but it is a genuine long-term moat question. ARB's proprietary fitment data, accumulated across 50 years of ICE vehicle development and representing one of its deepest competitive advantages, must be rebuilt from scratch for each new EV or hybrid platform.
Summary
The bear case for ARB is not that the business will fail. It is that the next two to three years may deliver earnings that continue to disappoint relative to expectations in a business where the valuation, even after a greater than 55% fall from peak, may not yet fully reflect the duration of the headwinds. The combination of currency exposure, soft domestic new vehicle sales, OEM lumpiness, a US expansion that is progressing but genuinely early stage and a fitter technician shortage creates a scenario where even a high quality business generates flat or declining earnings for an extended period.
