1. High debt levels - Stornoway Diamond Corporation has a significant amount of debt, which can limit its financial flexibility and increase its risk profile compared to peers with lower debt levels.

2. Volatile diamond prices - The company's profitability is heavily dependent on diamond prices, which can be highly volatile. This exposes Stornoway Diamond Corporation to potential fluctuations in revenue and profitability compared to peers with more diversified revenue streams.

3. Reliance on a single mine - Stornoway Diamond Corporation operates primarily through its Renard Mine in Quebec, Canada. This concentration of operations increases the company's vulnerability to any disruptions or operational issues at the mine, compared to peers with multiple mines or diversified operations.

4. Limited production capacity - The company's current production capacity is relatively small compared to some of its peers. This can limit its ability to take advantage of favorable market conditions or meet growing demand, potentially impacting its market share and revenue growth.

5. Geographic concentration - Stornoway Diamond Corporation's operations are primarily focused in Canada, which exposes the company to specific regional risks such as regulatory changes, political instability, or adverse weather conditions. Peers with more geographically diversified operations may have a lower risk profile in this regard.

6. Lack of vertical integration - Unlike some of its peers, Stornoway Diamond Corporation does not have significant vertical integration in its operations. This means that the company may have less control over the entire diamond value chain, potentially limiting its ability to capture additional value or mitigate risks compared to vertically integrated peers.
