Bullish Earnings DD on BIRK Under a Tariff-Reversal Catalyst
Show original post
I put the TLDR at the top cause I know you regards won't read the bulk of this:
- Tariffs pressured this company's stock price throughout 2025, causing it to drop from its highs of $60+. Currently trading in $39-$40 range.
- Birkenstock lowered guidance in the December 2025 Earnings due to Tariffs and FX headwinds. Their all-in tariff rate should have been ~30% during the December 2025 and again in the February 2026 earnings call
- Since then, Supreme court ruled IEEPA illegal, they now qualify for IEEPA Tariff refunds, and recently, section 122 was ruled illegal by the trade courts
- Currently, the all-on tariff rate should be ~20% at the maximum, potentially only 8-10% if nothing replaces 122 that specifically targets European footwear.
- May 13th (BMO) will be the first time they will be able to address the now improved tariff situation since they lowered guidance in December.
- This leads me to believe there are 3 catalysts going into May 13th earnings: tariff rate reduction, Tariff refund claim disclosure, guidance revision.
- This is a luxury apparel growth stock trading like a value stock because it has been highly shorted due to tariffs eating into margins. And now those tariffs might go away entirely, plus a refund for past tariffs.
- If management signals tariff headwinds won't be as bad as previously guided, the narrative shifts to it being a growth stock. Under that scenario, a 19 forward P/E is much more reasonable and that puts BIRK at $55.
Full DD:
Guidance Revision
At their December earnings, management guided FY2026 with a 100bps tariff headwind baked into both gross margin and EBITDA margin guidance that assumed the ~30% all-in rate persisting through the year. That assumption is now wrong by at least 10 percentage points. They haven't had a chance to update it publicly.
February's call maintained full-year guidance because the SCOTUS ruling happened eight days later and Section 122 took effect four days after that. Management had no basis to update numbers on the Feb call. May 13th is the first opportunity to do so, and I don't think it's been priced in due to how thinly traded and overly shorted this stock got during the Iran war.
If the 100bps tariff headwind assumption shrinks to reflect the lower rate, that flows directly into updated gross margin and EBITDA margin guidance. America is their largest market, so the margin improvement will be substantial. They also have a strong record of beating the streets estimates, so I hope a strong beat tomorrow means they lift their guidance.
IEEPA refund disclosure
BIRK almost certainly qualifies for IEEPA tariff refunds. CBP opened the CAPE refund portal on April 20th. The refundable amount is the IEEPA-attributable layer (roughly 10 percentage points) on all German imports entered between April 2025 and February 24, 2026. Other footwear companies disclosed CAPE filings on the day the portal opened. Analysts will ask BIRK the same question tomorrow.
Section 122 now Illegal too
The CIT ruled Section 122 unlawful on May 7. The injunction only covers named plaintiffs (Burlap & Barrel, Basic Fun), so BIRK is still paying the 10% rate. But the legal foundation for a future refund claim now exists. Management will be asked whether they're preserving entry documentation to protect those rights. Given the July 24 expiry of Section 122 regardless, and the political impossibility of congressional extension, the 10% rate is likely gone after July 24. Their rate would then drop to 8-10%, from its current ~20% rate, which is what their tariff rate was pre-liberation day. The risk here is that future tariffs may increase it back to 20%, but I have reason to believe that the next round of tariff attacks may not even touch Birkenstock.
Why I think they will overcome future tariff pressures:
Trump has specifically directed his recent tariff threats at EU steel, aluminum and autos, not apparel. EU footwear and leather goods have faced no equivalent product specific action beyond the now illegal IEEPA reciprocal rate. The Section 301 investigation initiated in March 2026 does include the EU, but it targets structural excess manufacturing capacity, aka countries/industries that have cheap manufacturing where USA has bigger deficit. That means apparel companies with Chinese and Southeast Asian factories will get hit. EU autos and steels will get hit, but German made sandals? Not on really on this administrations radar based on any of its messaging. Their direct footwear peers (ONON, Deckers, Nike) all are exposed to Asian manufacturing tariffs, while Birkenstock manufactures 95% of their product in Germany. That gives them a meaningful advantage to shake off its current tariff-based valuations.
Birkenstock is approaching May 13 with a lower all-in rate, a refund claim for overpaid duties, and a manufacturing geography that does not appear to be in the crosshairs of Trump's next wave of tariffs. If the tariff story really changes the way I see it changing, its share price should no longer be suppressed, its valuations should reflect that it is a growth stock, not a value stock.
Growth Prospects:
On the demand side, Birkenstock's growth trajectory has been self-evidently strong, FY2025 delivered record revenue of €2.1 billion, up 18% in constant currency, with Americas growing 18% in constant currency. Demand signal holds up in search data too: Google Trends data shows "Birkenstock clogs" maintaining consistent baseline interest throughout the year with a significant spike into the December 2025 holiday season, which analysts have noticed. They are rapidly expanding in Asia, their production is ramping up and they're growing their direct-to-consumer sales (which is a high margin business). These are very positive tailwinds for growth, completely independent of tariffs.
The macro backdrop also skews in Birkenstock's favor relative to most of its apparel and footwear peers. The US consumer economy is visibly K-shaped, with premium brands like Ralph Lauren, Tapestry, American Express, United, and Delta all exceeding expectations as their affluent customer bases spent freely on high-margin goods, while value-focused brands serving lower-income households reported pullbacks. Birkenstock sits firmly in the first camp. We all know we are in a K-shaped economy, and Birkenstock is a benefiter of that. Recently, it traded down with other retail apparel and footwear stocks during the Iran war, when it really shouldn't. They have solid demand that is not going away, it should be priced similar to Ralph Lauren.
Valuation:
Per Fintel, Birkenstock had a reported ~19% short float and ~6.8 days to cover. This strikes me as high for a company that has 18% revenue growth and real growing profitability. The primary reason for it being shorted has to be tariffs. BIRK's forward P/E, and PEG are clearly very suppressed compared to industry standard for Apparel Stock P/E's especially compared to companies like Nike that are disadvantaged by their China/southeast Asia manufacturing.
Birk's current forward PE is 13.67 and its PEG is at 0.87 (per finviz). If the narrative around Birkenstocks tariff woes changes after tomorrows earning call, these ratios are insane discounts. A re-pricing of Birkenstocks share price would send it soaring. As of January 2026, apparel stocks had a forward P/E of 24.89 and a PEG of 1.99 (Per NYU study: Price Earnings Ratios). Birkenstock simply being priced at those ratios would put the stock price at $71- $89. I don't think it will go that high immediately post earnings, but the average analyst values this stock at $57. Further, Michael Burry is buying this stock too. It's clearly undervalued, and May 13th earnings calls has enough potential catalysts to reverse its year-long bearish downtrend (that reversal is already starting to form in its graph).
A narrative shift from the tariff pressures could send this stock soaring. My personal price target is $55, which would put it at a Forward P/E of 19 and a PEG of 1.22. By comparison, Nike, a company with significantly more tariff and growth pressure, trades at forward P/E of ~23 and a PEG of ~8.46. Ralph Lauren, a fellow luxury apparel stock, trades at 19 forward P/E and 1.08 PEG. By current street predictions, Birkenstock is expected to grow earnings by 18%, whereas Ralph is expected to grow 10%. But BIRK has better debt ratios than Ralph Lauren (3.13 vs 2.1 and 0.49 vs .99 for current ratio and debt/equity ratio respectively). For you regards who don't understand that, it has much less debt than Ralph Lauren, while growing faster with cheaper valuations. This part can go on a lot longer and it's obviously very subjective, but a forward PE of 19 and a PEG of 1.22 for a company that's growing and already profitable with low debt really doesn't sound so farfetched, eh?
Disclaimer: I don't expect a 40% move in one day, this not a crowded stock where that can happen. If it transitions from non-crowded to crowded, it's possible, but I'm not counting on it.
Currently, I think a move up to $45 post earnings is more likely if they post good earnings beat and my catalysts materialize on the earnings call. I would expect it to run higher once trump does his weekly taco. Stock rotation is buzzing in the headlines today too, which would help allocate some flows to mid-cap consumer cyclical industries stocks that are showing some promise.
The Bottom Line
Unlike other meme stocks on here, Birkenstock has real growth and proven profitability. $39 is simply too cheap by a lot of metrics. This is a rare find and strong buying opportunity. Given that tmrw will be the first time Birkenstocks management will address the improved tariff situation, these catalysts have a real chance to materialize. If that happens, I expect the narrative to shift from tariffs to growth, and there's no way this stock stays at the $39 range for much longer.
Do your own research. I have a horrible track record, but I think I'm really on to something this time.
Positions:
- Note: I did make $6.5K on $42 Jul calls and then rolled to the $45 calls. In retrospect, should have taken profit and re-entered on the pullback, but live and learn.
- Plan is sell 20-30 contracts after earnings are released and let the rest run for another week or two depending on the guidance and overall market movements.
- If I were to enter this trade right now, instead of weeks ago, I would consider the $37.5 or $40 May calls and then sell them and buy shares to hold for $55+ (NOT FINANCIAL ADVICE)
The OP presents a bullish thesis on Birkenstock Holding PLC (BIRK) ahead of its May 13 pre-market earnings, with the core view that the market is pricing BIRK as an undervalued consumer stock heavily pressured by tariffs, while recent changes in the U.S. tariff legal environment could reverse that narrative. The OP argues that BIRK’s decline in 2025 from above 60 dollars to around 39-40 dollars was mainly driven by U.S. tariffs, FX pressure, and rotation out of consumer retail stocks. In its December 2025 earnings report, the company incorporated around a 100bp tariff drag into its FY2026 gross margin and adjusted EBITDA margin guidance, while the then-implied “around 30% all-in tariff rate” has materially improved because IEEPA tariffs were rejected by the Supreme Court, the CAPE refund channel was opened, and the Section 122 10% global surcharge was also ruled unlawful by the trade court. The OP views the May 13 earnings call as the first public window for the company to update its tariff assumptions and expects three potential catalysts: a lower effective tariff rate, disclosure of IEEPA refund applications, and an upward revision to FY2026 guidance or at least softer language around tariff headwinds. The OP further argues that about 95% of BIRK’s products are manufactured in Germany or the EU, so compared with footwear and apparel peers such as Nike, Deckers, and ONON, which have higher exposure to Asian manufacturing, BIRK is less likely to be hit by future tariffs targeting China or Southeast Asian supply chains. Meanwhile, Trump’s recent focus has been more on EU steel, aluminum, and autos, and may not necessarily target German sandals specifically. On demand, the OP cites FY2025 revenue of €2.1bn, 18% constant currency growth, 18% constant currency growth in the Americas, DTC expansion, Asia growth, Google Trends search interest in clogs, and the willingness of high-income consumers in a K-shaped economy to keep spending on premium brands, to argue that BIRK is not merely a tariff trade but a genuinely growing high-margin brand. On valuation, the OP cites finviz forward P/E of 13.67, PEG of 0.87, NYU Damodaran apparel industry forward P/E of 24.89 and PEG of 1.99, plus an average analyst price target of around 57 dollars, arguing that if the market reprices BIRK as a growth stock rather than a value stock, it could reach 55 dollars, implying a forward P/E of 19 and PEG of 1.22. The OP also mentions Michael Burry’s purchase as sentiment support. The position screenshot shows that the OP is not merely talking: they hold 703 shares of BIRK, with a market value of about 27,402.94 dollars, average cost of 40.96 dollars, screenshot price of 38.98 dollars, and an unrealized loss of around 1,394 dollars. They also hold 69 BIRK 45 dollar calls expiring July 17, 2026, with a market value of around 8,970 dollars, average cost of about 268.19 dollars per contract, screenshot price equivalent to 1.30 dollars per share, and an options loss of around 9,535 dollars. This shows it is an earnings/narrative-reversal trade with meaningful leverage and time-value risk. The biggest flaw is that the OP directly extrapolates tariff-related legal victories into BIRK margin recovery and management raising guidance. However, there is uncertainty over whether BIRK is the importer of record, how much refund it can receive, the timing of refund recognition, whether tariffs have already been passed through via pricing, whether Section 122 relief extends to non-plaintiffs, and whether the government will use Section 301 or other tools to replace the tariffs. Meanwhile, short-interest data, valuation multiples, and Burry’s holding are more about sentiment and relative valuation support, and do not prove that a catalyst will occur on earnings day.
The comment sample is very small, with only 8 comments and 5 top-level comments, and many are WSB-style jokes, so it should not be treated as thorough community due diligence. The substantive discussion mainly focuses on position risk and the nature of the target as a “sandal company.” The top-voted comment, “mad calls for sandals lmao,” mocks the OP for using a large number of call options to bet on the earnings of a sandal company. Its real meaning is that the trade is overly speculative and the stock lacks meme-explosion potential. The OP personally replies that it is “definitely insane” and “high risk,” but adds that Birkenstock is not only sandals; it also has closed shoes and clogs, those categories are growing, and sandals have high gross margins, which is used to push back against the simplistic “just sandals” framing. Another comment quotes the OP’s self-description, “I have a horrible track record,” effectively warning that the OP’s historical win rate is poor and reducing the credibility of the DD. The comment about Michael Burry is a bot-like long meme portraying Burry as showing up everywhere and participating in all kinds of topics, implying that “Burry bought it” should not be treated as an overly important investment basis. The OP also responds jokingly by linking Burry and Birks, without providing new factual support. The remaining User Report comments are just account history and WSB bot information with low informational value. Overall, the comments do not contain serious rebuttals or support regarding the core arguments around IEEPA, Section 122, BIRK’s tariff exposure, or refund accounting treatment. They are mostly risk-related jokes about the options position and the “sandal stock” narrative. The OP’s replies acknowledge high risk but maintain the product-line and gross-margin logic. If there is any community consensus, it is only that this is a high-risk WSB-style earnings bet, not a deep thesis thoroughly validated by the comment section.
