Kaufman & Broad SA today announces its results for the first nine months of 2023 (from December 1 to August 31, 2023). Nordine Hachemi, Chairman and Chief Executive Officer of Kaufman & Broad, said:

" The commercial and financial results for the 3rd quarter of 2023 are consistent with those for the 1st half of 2023.

Housing orders were down 12.6% in volume terms over the first 9 months of the year, compared to an estimated decline of around 35.1 %(c) over the same period for the whole market.

In this context, Kaufman & Broad continued to apply a rigorous strategy of adjustment to market conditions, including:

- focus on block sales to institutional investors,
- maintain a very high level of requirement in terms of Take up period rates.

Furthermore, the group still relies on a solid land reserve and an overall backlog of 2.7 billion euros representing approximately 2 years of activity.

The work of Austerlitz Operation A7/A8 continues to proceed according to schedule.

The financial structure remains very solid, as evidenced by Fitch's confirmation of Kaufman & Broad SA's Investment Grade rating. The group's net cash (b) amounted to 201.2 million euros at August 31, 2023.

Kaufman & Broad relies on its ability to adapt its offering to new market conditions, the high level of its Backlog and land portfolio as well as its balance sheet strength to seize opportunities and, beyond that, take full advantage of the recovery in a healthy market.

The group confirms its outlook for the whole of 2023:

- attributable net income is expected to increase by around 20%,
- the recurring operating income ratio is expected to be around 8%,
- revenue should grow by 6 to 10%,

- in addition, positive net cash(b) should be higher than €50 million(d) mentioned last July. '

GLOSSARY

Backlog or (order book ) : it covers, for Sales in the Future Completion Status (VEFA), undelivered reserved units for which the notarially signed deed of sale has not yet been signed and undelivered reserved units for which the notarially signed deed of sale has been signed up to the portion not yet taken into revenue (on a 30% advanced program, 30% of the revenue of a housing for which the notarially signed deed of sale has been recorded as revenue, 70% are included in the backlog). The backlog is a summary at a given point in time that makes it possible to estimate the revenue still to be recognised in the coming months and thus support the Group's forecasts - it being specified that there is an uncertain portion of the transformation of the backlog into revenue, particularly for bookings not yet recorded.

BEFA: the Bail in the Future Completion consists of a user renting a building even before it is built or restructured.

Working Capital Requirement (WCR): This arises from cash flow mismatches: disbursements and receipts corresponding to operating expenses and revenues required for the design, production and marketing of real estate programs. The resulting simplified expression for WCR is as follows: these are current assets (inventory + trade receivables + other operating receivables + advances received + prepaid income) less current liabilities (trade payables + tax and social security payables + other operating liabilities + prepaid expenses). The size of the WCR will depend in particular on the length of the operating cycle, the size and duration of storage of work-in-progress, the number of projects launched and the payment terms granted by suppliers or the profile of payment schedules granted to customers.

Free cash flow: free cash flow is equal to cash flow from operations less net operating investments Of the year.

Operating cash flow: operating cash flow after finance costs and tax is equal to consolidated net income adjusted for the share in net income of associates, joint ventures and income from discontinued operations and calculated income and expenses.

Financial capacity: corresponds to cash and cash equivalents plus undrawn credit facilities

CDP : (formerly Carbon Disclosure Project): Measuring the environmental impact of companies.

Take up period: Take up period is the number of months it would take for available units to be sold if sales continued at the same rate as in previous months, i.e., the number of units outstanding (available supply) per quarter divided by the number of orders per quarter in the past divided by three.

Dividend The dividend is the portion of the Company's net annual profit distributed to shareholders. Its amount, proposed by the Board of Directors, is submitted to the shareholders for approval at the General Meeting. It is payable within a maximum of 9 months after the end of the financial year.

EBIT: The EBIT corresponds to the operating income for the period, calculated at the gross margin deducted by operating costs for the current period.

Gross financial debt or financial debt: gross financial debt consists of long term and short term financial liabilities, hedging financial instruments relating to liabilities constituting gross financial debt and accrued interest on the balance sheet items constituting gross financial debt.

Net debt or net financial debt: the net debt or net financial debt of a company is the balance of its gross financial debt (or gross financial debt), on the one hand, the available and financial investments forming its 'Active cash' on the other hand. It represents the credit or debit position of the company vis-à-vis third parties and outside the operating cycle.

Investment grade : investment grade means that a financial instrument or a company has a relatively low risk of default.

LEU: LEU (Equivalent units delivered) is a direct reflection of the business. The number of 'LEU' is equal to the product (I) the number of housing units in a given programme for which the notarially signed deed of sale has been signed and (II) the ratio of the amount of land expenditure and construction expenditure incurred by the group on the said programme to the total expenditure budget of the said programme.

Gross margin : corresponds to sales less cost of sales. The cost of sales includes the price of land, related land costs and construction costs.

Commercial offer : it is represented by the sum of the stock of available for sale housing on the date in question, that is,all the housing units not reserved on that date (net of unopened commercial tranches).

Land portfolio : This includes land to be developed. I.e. land for which a deed or a promise to sell has been signed, as well as land under study, i.e. land for which an deed or promise to sell has not yet been signed.

Gearing ratio: this is the ratio of net debt (or net financial debt) to consolidated equity. It measures the risk of the company's financial structure.

Orders : measured in terms of volume (units or units) and value, they reflect the group's commercial activity. Their inclusion in revenues is conditional on the time required to transform an order into a notarized deed of sale, which generates the income statement. In addition, in multi-family housing programs including mixed-use buildings (apartments, business premises, shops, offices), all surfaces are converted into housing equivalents.

Orders (in value ): they represent the value of real estate resulting from reservation contracts signed including all taxes for a given period. They are mentioned net of the withdrawals noted during the said period.

Managed residences : managed residences, or service residences, are real estate complexes consisting of housing (Homes or apartments) for residential use offering a minimum of services such as reception, supply of linen, cleaning and maintenance of housing as well as the provision of breakfast. There are several types of residences: Student residences are apartment complexes, mostly studios equipped with a kitchenette and furnished, located close to schools and universities and close to public transport; tourist residences, located in high potential tourist areas, offer in addition to the usual services of infrastructures such as swimming pools, sports grounds, sometimes saunas, hammams, whirlpool baths, children's club; business residences are an alternative to traditional hotels, consisting of studios (approximately 80%) and 2-rooms, located in the city center or near important business centers and systematically well served; finally, senior residences (including also residences for dependent or nondependent elderly people – "Ehpad"), which make it possible to anticipate the aging of the population, accommodating people from 55 years and beyond; their clientele is mixed: Tenants and owners.

CSR (Corporate Social Responsibility): corporate Social Responsibility (CSR) is the contribution of companies to the challenges of Sustainable Development. The approach consists of companies taking into account the social and environmental impacts of their activity in order to adopt the best possible practices and thus contribute to the improvement of society and the protection of the environment. CSR makes it possible to combine economic logic, social responsibility and eco-responsibility (definition of the Ministry of Ecology, Sustainable Development and Energy).

Sell-Through rate: The Sell-Through rate (Rst) represents the percentage of initial inventory that sells monthly on a real estate program (sales/month divided by initial inventory); i.e., monthly net reservations divided by the ratio of beginning-of-period inventory plus endof-period inventory divided by two.

Ebit rate: expressed as a percentage, it corresponds to current operating income cad at gross margin less current operating expenses divided by sales

Cash and cash Equivalents : this corresponds to cash and cash equivalents on the asset side of the balance sheet, including all available cash and cash equivalents, marketable securities (short term investments and term deposits) and book balances.

Net cash: It corresponds to 'negative' net debt, or 'negative' net financial debt, as for the company the balance of cash and financial investments forming its 'active cash' is greater than the amount of its gross financial debts (or gross financial debt).

Units : units or Units are used to determine the number of dwellings or housing equivalents (for mixed programmes) of a given programme. The number of housing equivalent units is determined by relating the surface area by type (business premises, shops, offices) to the average surface area of the housing units previously obtained.

VEFA: sale in the Future of Completion is the contract whereby the seller immediately transfers to the purchaser its land rights as well as the ownership of the existing buildings. The future works become the property of the purchaser as they are executed; the purchaser is obliged to pay the price as the works progress. The seller retains the powers of the project owner until the work is accepted.
