Should You Invest in Le Slip Français? A French IPO Balancing Industrial Recovery and Risky Bet

An IPO Built Around a Turnaround

Le Slip Français plans to go public on Euronext Growth Paris under the ticker symbol ALLSF and the ISIN code FR0014018Y10. The offering price is set at 14.80 euros per share. The transaction includes both a capital increase and the sale of existing shares.

The company is set to issue a maximum of 337,838 new shares, representing approximately 5 million euros gross. Concurrently, the two historical shareholder funds may sell 471,742 existing shares in the initial size of the offer, equivalent to around 6.98 million euros. With the extension clause and the overallotment option, the sale of existing shares could reach around 10.8 million euros.

This structure is important: the operation not only finances the company's development, but it also allows the historical funds to obtain partial or greater liquidity depending on demand. The executives themselves are not selling any shares during the operation, which limits negative signaling.

However, investors should note that the listing is not solely for raising funds aimed at growth. The company states that the net proceeds from the capital increase should amount to approximately 3.7 million euros, after 1.3 million euros in offering-related expenses. These funds are intended to strengthen the industrial platform, accelerate commercial and marketing development, and support working capital. Therefore, the listing comes at a pivotal moment: Le Slip Français claims to have emerged from a difficult period and aims to finance the next phase of its model.

2025 Figures Reveal a Real Turnaround

The main financial argument of the case lies in the return to profitability in 2025. On a pro forma basis, Le Slip Français reports a revenue of €21.127 million, an adjusted EBITDA of €2.123 million, a pro forma operating profit of €1.560 million, and a pro forma net profit of €724,000. These figures mark a significant improvement compared to the 2024 social accounts, which showed a net loss of €1.502 million. The pro forma gross margin reaches 59% in 2025, up from 56% a year earlier, driven by product mix optimization and procurement management. The free cash flow is also significant, with an EBITDA to cash conversion rate of 70%.

The turnaround is thus real. The company has shifted from a strained model to one that is profitable again. However, consolidated net financial debt still amounts to €3.472 million by the end of 2025, albeit showing a notable improvement from the €5.195 million recorded in the 2024 social situation. The net debt to EBITDA ratio stands at 1.6 times, compared to 7 times a year earlier. At first glance, the valuation might seem reasonable. The theoretical post-offer market capitalization stands at approximately €19.2 million. Relative to the pro forma revenue for 2025, it accounts for about 0.9 times the sales.

By adding the consolidated net debt of €3.5 million and subtracting the expected net proceeds from the capital increase of approximately €3.7 million, the adjusted enterprise value comes to around €19 million, roughly 0.9 times the pro forma revenue. The adjusted EBITDA multiple is approximately 8.9 times. These levels do not seem excessive for a well-known consumer brand, provided that growth and margins are maintained.
However, the net profit multiple is significantly more demanding: with €19.2 million in capitalization for €724,000 in pro forma profit, the stock is offered at about 26.5 times the 2025 net profit. Therefore, the investor is not buying a company undervalued on its current profits. They are buying a promise of continued recovery.

The Investment Thesis Relies on Converting Brand Awareness into Volume

Le Slip Français possesses a clear asset: its brand. The group claims a spontaneous brand awareness of 60% in France, according to a YouGov study conducted in October 2025. However, its market share in men's underwear remains limited to about 4% in a French market estimated at 500 million euros. The company thus presents a conversion potential: turning an already well-known brand into more frequent purchases and additional market share.

The stated goal is to increase this market share to around 8% by 2030, which would mean doubling its 2025 revenue. This ambition aligns with the repositioning effort underway. Le Slip Français no longer wants to be just a premium brand or a made-in-France gift bought occasionally. It aims to become an everyday brand, more accessible, more recurring, and capable of selling higher volumes.

The company reports having halved its average price from 40 to 20 euros, streamlined its range by 30%, tripled its volumes, reduced its industrial cost by 45%, and gained more than 200,000 new customers since 2023 as part of its pivot. This change is strategic. Underwear is a frequently used product: to create genuine purchase recurrence, the brand must move away from being a militant or humorous gift and into the realm of everyday essentials. This is precisely what Le Slip Français is attempting to do. If this transformation succeeds, the potential is there. However, it requires that the price reduction be offset by increased volumes and industrial gains.

One indicator deserves attention: the cost of acquiring a new customer is announced at 15 euros, with an average order value of 80 euros including taxes, resulting in a margin-to-acquisition cost ratio of 3.3 times from the first order. For comparison, the average acquisition cost in fashion e-commerce ranges from 80 to 110 euros. If these figures hold over time, the brand possesses an unusually profitable growth lever in the textile sector.

The Industrial Tool is the Key Strategic Asset of the Portfolio

The most interesting aspect of the IPO might not be the brand itself, but the industrial infrastructure that Le Slip Français aims to build around Bonne Nouvelle. This fully owned subsidiary is presented as a semi-automated factory capable of producing about 60% of the group’s underwear purchases. The investor presentation highlights a capacity of 25,000 items per week, one million items manufactured per year, a 24% increase in sales volumes, working capital reduced by half in three years (from 88 to 44 days), and a 45% reduction in production costs.

This industrial integration is crucial as it addresses the major structural weakness of French-made textiles: cost. Many brands can promote French manufacturing, but few can produce in volume, reduce lead times, limit inventory, and improve operational flexibility. Le Slip Français wants to demonstrate that a French-made model can become competitive by combining standardization, semi-automation, volume increase, and product complexity reduction.

The company goes further by presenting a development strategy of “Made in France as a service,” offering the capability to also produce for third-party brands. If this model proves successful, the company might evolve from being merely an underwear brand to becoming a French industrial textile platform. However, this part of the thesis remains the most demanding: it requires investments, rigorous execution, sufficient volumes, and the ability to maintain quality while reducing costs.

The group hasn't limited itself to Bonne Nouvelle. In early 2026, Le Slip Français integrated two new production units: La Belle Paire, a joint venture with a 50.1% stake alongside sock manufacturer Broussaud in Haute-Vienne, equipped with 13 knitting machines and capable of producing 400,000 socks per year, and Fier(T), a multi-product workshop fully owned in Île-de-France, equipped with 30 machines including two automats, employing 25 people. These acquisitions indicate that industrial integration is not just a theoretical plan but a strategy already being executed even before the stock market listing.

High Risks Explicitly Indicated in the Prospectus

The prospectus advises against idealizing the situation. Several issuer-specific risks are rated as highly critical. The first risk relates to the group's ability to sustainably restore satisfactory profitability and generate positive cash flows over time. This is the crux of the matter: the return to profitability in 2025 is encouraging, but it does not yet provide proof over several fiscal periods. The company must demonstrate that the price reductions, volume increases, industrial insourcing, and product mix are sufficient to maintain the margin.

The second risk concerns financial liquidity. The group remains tied to an agreement concluded in April 2025 with its shareholders and lenders. This agreement extends the debt maturity until 2030 but imposes constraints. It specifically prohibits the distribution of dividends until the lenders are fully repaid. It also imposes monitoring obligations and a mandatory early repayment mechanism starting in 2026, amounting to 30% of EBITDA exceeding a reference EBITDA, provided that net cash remains above 2 million euros.

For shareholders, this means that the stock should not be purchased with an income-oriented approach. There are no dividends expected in the short term. It also means that part of the future cash flows might be directed towards debt repayment rather than growth or shareholder compensation.

A Turnaround Small Cap, Not a Defensive Stock

Another major risk concerns the stock market itself. Le Slip Français will be listed on Euronext Growth, a market suited for growth SMEs, but often less liquid than the regulated market. The prospectus categorizes the lack of prior listing and the possibility of insufficient liquidity as high-risk factors.

This point is crucial for individual investors. A company may look promising on paper but can become difficult to sell under favorable conditions if trading volumes are low. Volatility can also be significant, especially if the initial post-IPO publications disappoint.

The seasonality of sales is another factor of vulnerability. The fourth quarter accounted for 36% of revenue in 2025. This concentration aligns with the brand's history, long associated with gifts. However, it creates a strong dependency on year-end commercial peaks. A failed campaign, stock issues, production tensions, or a slowdown in consumption can significantly impact the entire fiscal year. Furthermore, Le Slip Français remains a small company. With revenue of about 21 million euros, a net profit under 1 million euros, and still significant financial debt, the margin for error is limited. The company may be of interest, but it should not be mistaken for a defensive stock or an established brand whose profitability is already widely proven.

Is it Time to Invest? An Intriguing Report, but Only for Aggressive Profiles

The answer depends on the investor's profile. For a cautious investor looking for strong visibility, comfortable liquidity, a dividend, and profitability established over several years, Le Slip Français does not seem suitable. The stock has the characteristics of a turnaround small cap: real potential, clear history, strong brand, but high execution risk.

For an aggressive investor capable of accepting significant volatility, the investment case can be defended as a speculative line. The positive arguments are real: high brand recognition, still a low market share, price repositioning, return to profitability, integrated industrial tool, ambition to double revenue by 2030, and a target operating profit above 10% in the medium term. However, these elements still need to be confirmed in the accounts.

The main point of concern is valuation based on earnings: at approximately 26.5 times the pro forma net income for 2025, the stock is not offered at a distressed price. It assumes that 2025 marks the beginning of a sustainable cycle of profitable growth.

Le Slip Français is a case to watch, but be careful not to confuse investment with brand attachment. Buying at the IPO is only justified if one believes in the company's ability to turn brand recognition into sales volumes, its industrial tool into a cost advantage, and its return to profitability into sustainable profitability. At this stage, the prudent approach is to consider the stock as a bet on French industrial recovery.
