Key Factors Affecting the Results of Our Group’s Operations

Our results of operations and financial condition have been, and are expected to continue to be, affected by a number of factors which are set forth below:

Recent Events

Private Offering and Subsequent Registration of Ordinary Shares

On February 5, 2026, we closed on a private offering (the “Private Offering”) of 15,669,556 units (the “Units”) at a purchase price of US$0.575 per Unit. Each Unit consisted of one Ordinary Share, one Series A Warrant to purchase up to one Ordinary Share and one Series B Warrant to purchase up to one Ordinary Share. Each Series A Warrant has an exercise price of US$0.69 per share, and each Series B Warrant has an exercise price of US$0.805 per share. We received gross proceeds in the approximate amount of US$9,009,995, before deducting offering expenses payable by the Company, and excluding any proceeds that may be received by the Company from the exercise of the Warrants, and net proceeds of approximately US$8,913,848. The Warrants may be exercised either in cash or by cashless exercise and expire two years after issuance.

Results of Operations

Six-month period ended December 31, 2025 compared to six-month period ended December 31, 2024

The following discussion is based on our Group’s historical results of operations and may not be indicative of our Group’s future operating performance.

SUMMARY OF RESULTS OF OPERATIONS

FOR THE SIX MONTH PERIODS ENDED DECEMBER 31, 2024 AND 2025

Revenues

Revenues decreased by approximately GBP1,196,428 (US$1,608,837), or 27.8%, from approximately GBP4,307,291 (US$5,393,159) for the six-month period ended December 31, 2024 to approximately GBP3,110,863 (US$4,183,178) for the six-month period ended December 31, 2025.

The decrease occurred primarily during the second half of the 6-month period ended December 31, 2025 and was mainly attributable to delays in the commencement and execution of certain projects, which affected the timing of revenue recognition. Management has observed stronger project activity and revenue generation during the second half of the financial year compared with the second half of the six-month period ended December 31, 2025. However, such subsequent activity may not be indicative of results for future periods, and future revenue remains subject to customer requirements, project schedules, tender outcomes and general market conditions.

In the six-month period ended December 31, 2024, approximately GBP4,183,675 (97.1%) of total revenue came from supply & fit projects. For the six-month period ended December 31, 2025, approximately GBP3,077,277 (98.9%) of total revenue came from supply & fit projects.

Revenues by geographic location

Our revenues are primarily derived from our operations in the United Kingdom, with the balance being derived from our operations in Hong Kong. The following table sets forth our revenues in the United Kingdom and Hong Kong for the six-month periods ended December 31, 2024 and 2025.

Cost of revenues

Cost of revenues consisted of the cost of materials for our lighting fixtures and components, the costs of labor directly incurred for installation services in the customers’ facilities and other indirect costs. Cost of revenues decreased by GBP709,552 (23.4%) from GBP3,028,944 (US$3,792,541) for the six-month period ended December 31, 2024 to GBP2,319,392 (US$3,118,886) for the six-month period ended December 31, 2025. Our business model and cost structure remain the same in both six-month periods ended December 31, 2024 and 2025. The decrease in cost of revenues was primarily in line with the decrease in revenue.

Gross profit and gross profit margin

As a result of the foregoing, gross profit for the six-month period ended December 31, 2025 was approximately GBP791,471 (US$1,064,292) compared to approximately GBP1,278,347 (US$1,600,618) for the six-month period ended December 31, 2024. Gross profit for the six-month period ended December 31, 2025 decreased by GBP486,876 due to the drop in revenue of GBP1,196,428, or 27.8%, and proportionally smaller GBP709,552, or 23.4%, drop in cost of revenue. Accordingly, our gross margin decreased from 29.7% for the six-month period ended December 31, 2024 to 25.4% for the six-month period ended December 31, 2025 primarily because the decrease in revenue reduced the Company’s ability to absorb certain fixed direct costs and project-related overheads during the period.

Operating expenses

Total operating expenses increased from GBP1.3 million for the six months ended December 31, 2024 to GBP2.1 million (US$2.8 million) for the six months ended December 31, 2025. The increase was mainly due to higher legal and professional fees following the Company’s listing on the Nasdaq Capital Market in April 2025, reflecting additional staffing, reporting, compliance, legal advisory and other public company costs, higher employee compensation and benefits and higher research and development expenses. The increase was partially offset by lower selling and marketing expenses and a higher reversal of expected credit losses.

Legal and Professional fees. Legal and Professional fees increased by GBP484,998, or 315.1%, from GBP 153,911 (US$185,878) for the six-month period ended December 31, 2024 to GBP638,909 (US$859,140) for the six-month period ended December 31, 2025 as a result of expenses incurred in connection with the Company’s initial public offering and its listing on the Nasdaq Capital Market in April 2025. 

Employee compensation and benefits. Employee compensation and benefits increased by GBP350,833, or 54.0%, from approximately GBP649,882 (US$813,717) for the six-month period ended December 31, 2024 to approximately GBP1,000,715 (US$1,345,662) for the six-month period ended December 31, 2025. This increase was in line with our budget expectations.

Research and development expenses. Research and development expenses increased by GBP23,615, or 43.0%, from approximately GBP54,876 (US$68,710) for the six-month period ended December 31, 2024 to approximately GBP78,491 (US$105,547) for the six-month period ended December 31, 2025. Our increased research and development expenses resulted from deferring some research and development activities.

Selling and marketing expenses. Selling and marketing expenses primarily consisted of transportation and distribution costs of delivering materials to the customers’ premises and our marketing and promoting expenses. Selling and marketing expenses decreased by approximately GBP28,209, or 31.5%, to approximately GBP61,285 (US$82,410) for the six-month period ended December 31, 2025 compared to approximately GBP89,494 (US$112,055) for the six-month period ended December 31, 2024. This decrease resulted from a decrease in online marketing.

Expected credit loss allowance

The expected credit loss allowance was a credit of approximately GBP36,770 (US$46,040) for the six-month period ended December 31, 2024 compared to a credit of approximately GBP138,310 (US$185,985) in the six-month period ended December 31, 2025. The increase in the reversal of expected credit loss resulted from the write-off of a bad debt.

Other expenses, net

Other expenses, net decreased by GBP67,792, or 22.7%, from GBP298,287 (US$373,485) for the six-month period ended December 31, 2024 to GBP230,495 (US$309,947) for the six-month period ended December 31, 2025. This decrease was due to a 4.4% decrease in interest expense and a 67.2% decrease in interest expense-related party, partially offset by a 385.9% increase in exchange gain, net.

The decrease in interest expense between the six-month period ended December 31, 2024 and the six-month period ended December 31, 2025 was due to a decrease in loan principal. The decrease in interest expense - related party between those periods resulted from a decrease in loan principal.

The decrease in other income, net between the six-month period ended December 31, 2024 and the six-month period ended December 31, 2025 was primarily due to a decrease in gain on asset sale.

Loss before income tax expense

As a result of the above, the Company recorded losses before income tax expense of approximately GBP292,532 (US$366,279) and GBP1,545,287 (US$2,077,948) for the six-month periods ended December 31, 2024 and 2025, respectively.

Net loss

The Company realized net losses of approximately GBP292,532 (US$366,279) and GBP1,545,287 (US$2,077,948) for the six-month periods ended December 31, 2024 and 2025, respectively, after an income tax expense of approximately GBP Nil for both six-month periods.

Off Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Liquidity and Capital Resources

Our liquidity and working capital requirements are primarily related to our operating expenses. Historically, we have met our working capital and other liquidity requirements primarily through financial support from our shareholders or loans from banking facilities and, more recently, from the sale of securities in our Initial Public Offering and our 2026 Private Offering. Going forward, we expect to fund our working capital and other liquidity requirements from various sources, including cash generated from operations, loans from banking facilities and other equity and debt financings as and when appropriate.

Working capital

The following table sets forth a summary of the Company’s working capital deficit as of December 31, 2024 and 2025:

As of December 31, 2025, current assets were GBP6,670,468 and mainly consisted of prepayments and other receivables, net of GBP4,377,340, inventories, net of GBP1,101,442 and contracts receivable, net of GBP780,407.

As of December 31, 2025, current liabilities were GBP9,468,262 and mainly consisted of current portion of bank and other borrowings of GBP6,130,128, accruals and other payables of GBP1,120,147 and amounts due to related parties of GBP1,111,769.

As of December 31, 2024, current assets were GBP5,119,486 and mainly consisted of contracts receivable, net of GBP1,763,161, prepayments and other receivables, net of GBP1,441,497 and inventories of GBP1,136,191.

As of December 31, 2024, current liabilities were GBP10,205,278 and mainly consisted of current portion of bank and other borrowings of GBP7,808,146, accounts payable of GBP751,185 and accruals and other payables of GBP984,283.

Material cash requirements

Our cash requirements consist primarily of day-to-day operating expenses, capital expenditures and contractual obligations. We have limited credit available from our major vendors and are required to prepay for the majority of our inventory purchases, which further constrains our cash liquidity.

We believe that we have sufficient working capital for our requirements for at least the next 12 months from the date of this Report, absent unforeseen circumstances, taking into account the financial resources presently available to us, including cash and cash equivalents on hand, which include the net proceeds from our 2026 Private Offering, cash flows from our operations and other available sources of financing from banks and other financial institutions.
