C3is Inc. is a provider of international seaborne transportation services focused on moving drybulk and liquid cargoes across global trade routes. The company was incorporated under the laws of the Republic of the Marshall Islands on July twenty five two thousand twenty two to serve as a holding company for two subsidiaries each owning one drybulk carrier that were later contributed by Imperial Petroleum in connection with a spin off. After the spin off completed on June twenty one two thousand twenty three C3is Inc. began operating as an independent entity. It currently owns three drybulk carriers each classified as handysize vessels with deadweight capacities ranging from thirty two thousand to thirty three thousand six hundred sixty four tons. These vessels transport commodities such as iron ore coal grains bauxite phosphate and fertilizers. In addition C3is Inc. operates one Aframax crude oil tanker with a deadweight of approximately one hundred fifteen thousand eight hundred four tons that moves crude oil on spot market voyages. The firm has also entered into agreements to acquire two medium range product tankers built in South Korea in two thousand eight and two thousand eleven with deadweights of fifty thousand seven hundred sixty tons and forty seven thousand two hundred three tons respectively. Upon delivery expected in the second and third quarters of two thousand twenty six these tankers will join the fleet and increase total deadweight capacity to over three hundred eleven thousand tons. All vessels are placed under a management agreement with Brave Maritime a Greek based ship manager that provides technical crewing commercial administration and insurance services. The company’s headquarters are located in Athens Greece and it maintains a presence in key shipping markets through its global fleet deployment.

Revenue is derived mainly from charter hire paid by customers who employ the company’s vessels under time charter or spot market arrangements. Under a time charter the charterer pays a fixed daily rate for use of the vessel while the company retains responsibility for crew wages maintenance insurance and other operating expenses. This structure yields predictable cash flow especially when the vessels are on longer term contracts. Under a spot market charter the company earns freight that fluctuates with the balance of cargo supply and vessel availability allowing for higher earnings during strong markets but also exposing the company to downside risk when rates fall. As of March thirty one two thousand twenty six the three drybulk carriers were employed on short term time charters with one expiring in April two thousand twenty six and two expiring in May two thousand twenty six. The Aframax crude oil tanker was operating in the spot market generating revenue that varies with crude oil demand. The two medium range product tankers pending delivery are expected to enter service in the second and third quarters of two thousand twenty six and will initially be employed in the spot market before moving to a mix of spot and short term time charters. In addition to charter hire the company pays a management fee to Brave Maritime calculated per vessel per day and receives a small percentage of gross freight as part of the agreement. However the overwhelming portion of income comes from the charter hire earned on the fleet.

The drybulk and tanker shipping sectors are highly competitive and fragmented with many independent owners vying for a limited number of charters. Competitors include other owners of handysize supramax and panamax drybulk vessels as well as operators of aframax and medium range product tankers. Larger integrated shipping companies may have greater scale and access to capital but they also face higher overhead costs. C3is Inc. differentiates itself by maintaining a relatively young fleet of Japanese and Korean built vessels known for their build quality and durability. The partnership with Brave Maritime provides consistent technical oversight and ensures that the vessels meet international safety and environmental standards. This operational reliability helps the company attract charterers who value dependable service and compliance with regulations. Furthermore the business model blends time charter and spot market employment allowing the firm to adjust quickly to shifts in market conditions. When rates rise the company can benefit from spot exposure while the time chartered portion provides a floor of income. When rates decline the limited duration of the spot contracts reduces the potential loss compared to being locked into long term agreements at unfavorable levels. The company also monitors macroeconomic trends such as global industrial production and commodity demand which influence charter rates and seeks to time vessel acquisitions and disposals to capture value from market cycles.

The company’s charterers consist of a broad range of market participants including major national and private industrial users commodity producers and traders oil producers refineries and other commodity market actors. Although the filing does not disclose specific customer names it notes that revenue concentration is significant. In two thousand twenty five four customers accounted for sixty five percent of total revenue. In two thousand twenty four three customers represented fifty one percent of revenue. In two thousand twenty three two customers represented forty six percent of revenue. This pattern shows that while the company depends on a few key relationships it also continues to seek additional cargoes from diverse sources across different trade lanes. The vessels operate globally with frequent activity in the Middle East Far East Mediterranean North West Europe Africa United States and Latin America regions. This geographic spread helps the company access multiple cargo streams and reduces reliance on any single market. In addition the firm reports that a small number of charterers accounted for a majority of revenue in recent years highlighting the importance of maintaining strong relationships while pursuing new opportunities.
