The company remains an active SEC-registered corporation with its registered address at 2224 A. Bonifacio Street corner Pres. Sergio Osmena Highway, Bangkal, Makati City.
Harbor Star is an integrated maritime services provider operating throughout the Philippines and parts of Southeast Asia. Its core service lines are harbour assistance (tug escort and berthing support for ocean-going vessels), towage, lighterage, ship salvage and wreck removal, marine firefighting, oil-spill and hazardous-chemical response, diving and underwater marine works, ship and crew management, dredging, and PCAB-accredited marine construction. As of year-end 2024 the company reported a fleet of 51 tugboats, seven barges, one landing craft tank and one dredger operating from 11 base ports nationwide, and stated that it assisted 8,401 vessels during the year, up from 8,123 in 2023.
Harbor Star’s common shares have been listed on the Philippine Stock Exchange under the ticker TUGS since its initial public offering on 30 October 2013, in which it sold 30% of its issued share capital at PHP 1.88 per share. PSE trading data recorded a public float of 30.20% and 894,586,870 shares outstanding as of the retrieval date. The company is classified by the PSE under Services / Transportation Services.
For the financial year ended 31 December 2024, Harbor Star reported group consolidated service income of PHP 3.078 billion, up 14.1% from PHP 2.663 billion in 2023, and consolidated net income of PHP 189.1 million, up sharply from PHP 19.3 million in 2023. Harbour assistance was the largest revenue contributor at 61.8% of total service income (PHP 1.876 billion), while towage, lighterage and salvage revenue each declined year-on-year and construction revenue rose 190% to PHP 201.6 million. These figures are reported on a consolidated group basis rather than for the legal entity alone.
The registry’s on-file incorporation year (1988) is consistent with the SEC registration date identified above, though the exact registration date (5 July 1988, rather than the generic 1 January placeholder) and the company’s original registered name, Seatows, Inc., were not previously reflected.

Shareholders
Shareholders of Harbor Star Shipping Services, Inc.
Harbor Star Shipping Services, Inc. is listed on the Philippine Stock Exchange, and its shares are held partly by the public and partly by founding-family shareholders. Philippine Stock Exchange trading data recorded a public float of 30.20% of the company’s 894,586,870 outstanding shares as of the retrieval date, with the remainder held by non-public, reportable shareholders.
The largest disclosed individual shareholders, per the company’s Philippine Stock Exchange disclosure of director shareholdings following its 12 July 2022 annual stockholders’ meeting, were Geronimo P.

Together the two brothers’ direct holdings represented approximately 68% of the company’s current total shares outstanding. Other directors elected at that meeting disclosed only nominal individual holdings, ranging from 10,000 to 6,089,645 shares each.
These share counts reflect the July 2022 annual stockholders’ meeting disclosure, the most recent director-level shareholding breakdown located during this research. A more recent annual stockholders’ meeting took place in July 2026, but its shareholding disclosure could not be located, so the figures above may no longer be current.
Ultimate beneficial ownership
Available sources confirm that Geronimo P. Bella, Jr. and Ricardo Rodrigo P. Bella, sons of company founder Capt. Geronimo Bella, are the controlling family shareholders and serve respectively as Chairman/President and Executive Vice President. No formal beneficial-ownership filing with a calculated effective percentage beyond the direct and indirect shareholdings reported above was located, and no UBO threshold was supplied for this profile, so no separate UBO determination is made here.
Data availability
Shareholder information for this company is Partial: Philippine Stock Exchange disclosures identify director-level direct and indirect shareholdings as of July 2022 and an aggregate public float percentage as of the current retrieval date, but a complete, current register of all shareholders was not publicly located.

Officers
Directors and officers of Harbor Star Shipping Services, Inc.
Harbor Star Shipping Services, Inc.’s own website currently lists six board members, while the Philippine Stock Exchange’s company-information page records the board as comprising seven directors. This profile could not confirm the identity of a seventh currently serving director: a July 2022 Philippine Stock Exchange stockholders’ meeting disclosure named a seventh director, Ceasar Daniel Castro, who no longer appears on the company’s current board page, so the board may have changed since that date without a fully updated public listing being located.
The directors currently listed are: Geronimo P. Bella, Jr. (Chairman of the Board and President), Ricardo P. Bella (Director, also Executive Vice President), Ramon C. Liwag (Director), Ryota Nagata (Director), Gene S. De Guzman (Independent Director) and Gemma V. Sadiua (Independent Director). The company’s website separately lists four executive officers: Geronimo P. Bella, Jr. (Chief Executive Officer), Ricardo P. Bella (Executive Vice President), Capt. Lorenzo C. Caranzo (Operations Division Head) and Dany Cleo B. Uson (Chief Finance Officer and Investment Relations Officer).
No appointment, resignation or removal dates were published alongside these listings, and no former officers beyond the board-composition change noted above were identified. The information reflects the company’s own website as retrieved on 10 September 2026 and may not capture changes arising from the July 2026 annual stockholders’ meeting.

Group Structure
Group structure of Harbor Star Shipping Services, Inc.
Harbor Star Shipping Services, Inc. has no verified corporate parent. It is the top-level publicly listed entity in its group, majority-controlled by individual shareholders Geronimo P. Bella, Jr. and Ricardo Rodrigo P. Bella rather than by another company (see the shareholders block for details).
