# What are the key risks to Samsung Biologics’s growth trajectory?

# Key Risks to Samsung Biologics' (207940 KS) Growth Trajectory

Samsung Biologics (SBL) has just completed a horizontal split of its CDMO and biosimilar businesses, posted **+26% YoY revenue growth in Q1'26** to KRW 1,257B (OPM 46.2%) [10], and guides **+15–20% revenue growth for 2026** — a clear deceleration from **+30% YoY in 2025** (FY rev. KRW 4,557B; OP KRW 2,069B; OPM 45.4%) [9][8]. Against that backdrop, the principal risks to the growth trajectory cluster around four areas: (1) capacity ramp execution and competing technologies; (2) client-base concentration and the unwinding of conflicts via the spin-off; (3) external pricing/tariff pressure on the biopharma value chain; and (4) post-split structural overhangs.

## 1. Capacity execution & competing technologies

SBL's growth thesis is mechanically tied to plant ramp-up — Plants 1–4 are at full utilization with Plant 5 ramping, and the Rockville (Maryland) US facility was just acquired for $353M to add 60kL (with optionality to 100kL) [10]. The downside risks CLSA explicitly flags:

- **Delay/slower ramp of capacity expansion.** "Potential delays in the capacity expansion plan or a slower-than-expected ramp-up of manufacturing facilities could impede growth for Samsung Biologics" [1]. With FY26 guidance already stepping down to +15–20%, any slip on Plant 5 utilization or Rockville integration directly threatens guidance achievement.
- **Technology displacement by Wuxi Bio single-use bioreactors.** "If Wuxi Bio's single-use bioreactors experience an unexpected breakthrough, it could diminish the competitive advantage of Samsung Biologics' stainless tank capacity, potentially resulting in a loss of market share" [1]. SBL's moat is partly **regulatory** (Wuxi's weakness under the US BioSecure Act gives SBL share opportunities [4]); if that geopolitical tailwind reverses or single-use technology leapfrogs SBL's stainless platform, the share-gain narrative weakens.
- **Industry capacity utilization ceiling.** CLSA modeled industry capacity utilization rising to **79% by 2028** against an industry limit of **80%** [6] — i.e., the supply-demand crunch supporting SBL's pricing power is structurally close to peaking; new global greenfield builds beyond 2028 could reverse the tight market dynamic.

## 2. Client concentration & the conflict-of-interest legacy

- **Untapped tier-1 pharma.** Even after years of growth, two of the global top-20 pharma are **NOT yet penetrated**: **Amgen (#9)** and **Regeneron (#19)** [5][7]. Several others remain ambiguous ("?") including AbbVie and CSL [5]. Growth is structurally dependent on converting these laggards, and conversion is not guaranteed.
- **Bioepis conflict had real revenue drag pre-split.** CLSA's Q&A makes explicit that the firewall structure was *no longer sufficient*: "as Bioepis expanded, client concerns grew and began to impact competitiveness in contract bidding" [3]. The risk is that the spin-off only *partially* resolves this — if downstream clients remain suspicious, the order-momentum acceleration CLSA underwrites may not materialize.
- **Pipeline risk inside Samsung Bioepis (SBE).** "Any failures or delays of SBE's pipelines can also be one of risks" [1]. While the spin-off transfers SBE into Samsung Epis Holdings, SBL still has economic exposure via the new holding structure.

## 3. External pricing & tariff pressure on biopharma

- **Tariffs and biosimilar pricing pressure are already biting the sector.** CLSA flags this directly: "the biosimilar industry faces macroeconomic uncertainties due to the tariffs and pricing pressure, evidenced by Celltrion's case" [2]. CDMOs are indirectly exposed — if global pharma clients see margin compression from US tariffs/IRA pricing and pass it upstream to CDMO contracts, the **45%+ OPM** SBL currently posts is at risk.
- **US-facing capacity expansion increases tariff sensitivity.** The Rockville acquisition is part of a "global dual-site manufacturing network" strategy [10] — a defensive move that simultaneously raises USD-denominated operating cost exposure and integration risk just as the FX tailwind (which helped 2025 growth [8]) is unlikely to repeat at the same magnitude.

## 4. Post-split structural overhang

- **Unfavorable split ratio.** The 0.65:0.35 split ratio is "slightly unfavourable for the shareholders of SBL in the short term" [2] — minorities at the surviving CDMO entity may feel their earnings claim was diluted relative to SBE's NAV-based valuation.
- **Holding-company M&A optionality cuts both ways.** Samsung Epis Holdings plans to "acquire biotech platform companies" and pursue new modalities [3]. M&A execution risk and capital allocation risk now sit alongside operational risk.

## Summary Table — Key Risk Vectors

| Risk Bucket | Specific Risk | Source / Magnitude |
|---|---|---|
| Capacity execution | Plant 5 ramp / Rockville integration slip | Directly threatens FY26 +15–20% guide [10] |
| Technology | Wuxi Bio single-use bioreactor breakthrough | Could erode stainless-tank moat & share [1] |
| Regulatory tailwind reversal | BioSecure Act / China CDMO restrictions softening | Removes "Wuxi weakness" share opportunity [4] |
| Industry capacity | Industry utilization → 79% by 2028 vs. 80% cap | Tight-market pricing power near ceiling [6] |
| Client concentration | Amgen, Regeneron not yet penetrated | 2 of top-20 still "X" [5] |
| Conflict-of-interest residual | Spin-off may not fully restore client trust | "Began to impact competitiveness in contract bidding" pre-split [3] |
| SBE pipeline risk | Biosimilar / new-modality failures at SEH | Explicit risk factor [1] |
| Macro pricing | Tariffs + biosimilar pricing pressure (Celltrion case) | Already affecting peers [2] |
| Split mechanics | 0.65:0.35 ratio unfavorable to SBL minorities | Short-term overhang [2] |
| Growth deceleration | FY25 +30% → FY26 guide +15–20% | Already embedded in management guidance [8][9] |

## Bottom line

SBL's growth case is intact but **less front-loaded than it was 12 months ago**: revenue growth halves from 2025's +30% to a guided +15–20% in 2026 [8][9], and the multi-year story now depends on (i) Plant 5 + Rockville ramping cleanly, (ii) converting the last untapped tier-1 pharma clients now that the Bioepis conflict is structurally addressed, and (iii) the BioSecure-driven Wuxi displacement holding. The bigger risks are not idiosyncratic operational failure but **the simultaneous erosion of several tailwinds** — favorable FX, Wuxi geopolitical weakness, biologics capacity scarcity — that powered the 2023–25 re-rating.
