BUSINESS COMBINATION BUSINESS COMBINATION
As discussed in Note 1, “Summary of Significant Accounting Policies,” on September 2, 2025, the Merger by and among
Mechanics Bancorp (formerly known as HomeStreet, Inc.), HomeStreet Bank and Mechanics Bank was consummated. In
connection with the Merger, HomeStreet Bank merged with and into Mechanics Bank, with Mechanics Bank surviving the
Merger and becoming a wholly-owned subsidiary of Mechanics Bancorp. The Merger is considered a reverse acquisition in
which Mechanics Bank is the accounting acquirer (legal acquiree), HomeStreet Bank is the accounting acquiree and
Mechanics Bancorp is the legal acquirer. As the accounting acquirer, Mechanics Bank remeasured the identifiable assets
acquired and liabilities assumed in the Merger as of September 2, 2025 at their acquisition date fair values.
In connection with the Merger, each share of common stock, par value $50 per share, of Mechanics Bank voting common
stock issued and outstanding was converted into 3,301.0920 shares of the Company’s Class A common stock, no par value,
and existing shares of the Company common stock held by legacy Company shareholders were redesignated as the
Company’s Class A common stock. In addition, each share of common stock, par value $50 per share, of Mechanics Bank
non-voting common stock was converted into 330.1092 shares of the Company’s Class B common stock, no par value.
Class A common stock, which was previously known as Company common stock and was previously listed on Nasdaq and
traded under the symbol “HMST” through the close of business on August 29, 2025, commenced trading on Nasdaq under
the ticker symbol “MCHB” on September 2, 2025.
Immediately following the Merger, (1) legacy Mechanics Bank shareholders owned approximately 91.7% of the Company
on an economic basis and 91.3% of the voting power of the Company and (2) legacy Company shareholders owned
approximately 8.3% of the Company on an economic basis and 8.7% of the voting power of the Company.
The Merger was accounted for as a reverse acquisition, the purchase price was determined based on the number of equity
interests the legal acquiree would have had to issue to give the owners of the legal acquirer the same percentage equity
interest in the combined entity that results from the reverse acquisition. Therefore, the first step in calculating the purchase
price is to determine the ownership of the combined company following the Merger. The table below shows the calculation
to determine the ownership of the Company following the Merger using shares of Company common stock and Mechanics
Bank common stock outstanding as of September 2, 2025 and the fixed exchange ratio of 3,301.0920 applied to shares of
outstanding Mechanics Bank voting common stock and 330.1092 to shares of outstanding Mechanics Bank non-voting
common stock.

The following table provides the preliminary purchase price allocation and the assets acquired and liabilities assumed at
their estimated fair values as of the Merger date, resulting in a preliminary bargain purchase gain of $90.4 million. The
preliminary bargain purchase gain resulted from a combination of factors. First, HomeStreet was a company in financial
distress, losing $27.5 million after-tax in 2023, $144.3 million after-tax in 2024 and $8.9 million across the first two
quarters of 2025. As such, public market investors priced its shares at a significant discount to HomeStreet’s reported
tangible book value. Second, HomeStreet was subject to a failed merger attempt with FirstSun Capital Bancorp in 2024. 
This failed merger occurred due to an inability to obtain regulatory approval, which may have contributed to the sense of
financial distress around the company. Any failed merger causes difficulty retaining key employees, which may have
contributed to HomeStreet’s desire to find a new merger partner quickly. Third, HomeStreet recorded a valuation
allowance in 2024 against its deferred tax asset due to uncertainty surrounding its prospects of achieving future
profitability. However, Mechanics Bancorp is a profitable company and expects to be able to utilize the deferred tax assets
acquired from HomeStreet over time. $81.4 million of the net assets acquired from HomeStreet came from deferred tax
assets, which significantly contributed to the $90.4 million preliminary bargain purchase gain.
The estimates of fair value were recorded based on initial valuations at the Merger date and these estimates, including
initial accounting for deferred taxes, are considered preliminary as of September 30, 2025 and subject to adjustment for up
to one year after the Merger date. In many cases, the determination of fair value required management to make estimates
about discount rates, expected future cash flows, market conditions and other future events that are highly subjective in
nature and subject to change. Additional information may be obtained during the measurement period that could result in
changes to the estimated fair value amounts, and that could result in adjustments to the valuation amounts presented herein.
These estimates are considered preliminary as of September 30, 2025, are subject to change for up to one year after the
Merger date, and any changes could be material. The measurement period ends on the earlier of one year after the Merger
date or the date the Company concludes that all necessary information about the facts and circumstances that existed as of
the Merger date have been obtained.

The following is a description of the methods used to determine the fair values of significant assets and liabilities presented
above.
Cash and cash equivalents: The carrying amount of these assets is a reasonable estimate of fair value based on the short-
term nature of these assets.
Investment securities: Fair values for investment securities are based on quoted market prices, where available. If quoted
market prices are not available, fair value estimates are based on observable inputs including quoted market prices for 
similar instruments, quoted market prices that are not in an active market or other inputs that are observable in the market.
In the absence of observable inputs, fair value is estimated based on pricing models and/or discounted cash flow
methodologies.
Loans held for sale: The loans held for sale portfolio was recorded at fair value based on quotes or bids from third party
investors and/or recent sale prices.
Loans held for investment: A valuation of the loans held for investment portfolio was performed by a third party as of the
Merger date to assess the fair value. The loans held for investment portfolio were segmented into three groups, including
performing PCD loans, non-performing PCD loans and non-PCD loans. Non-performing PCD loans were evaluated based
on individual risk characteristics such as nonaccrual status. A subset of the performing PCD loans that did not meet specific
credit quality indicators were collectively assessed for PCD designation based on their vintage and financial asset type.
Certain commercial real estate loans with an unpaid principal balance of $2.4 billion, which were originated during the
COVID pandemic period between March 2020 and May 2023, have experienced more than insignificant credit
deterioration since origination as a collective. This population of loans is characterized by a historically low-interest rate
environment at origination and rates have since risen significantly as of the acquisition date, which has impacted this loan
population’s creditworthiness as a result of declining collateral values and debt-service coverage ratios. The ACL related to
these COVID pandemic period loans at the Merger date was $29.5 million.
The loans were further pooled based on loan type and risk rating bands. Most of the loans were valued at the loan level
using a discounted cash flow methodology. The methodology included projecting cash flows based on the contractual
terms of the loans and the cash flows were adjusted to reflect credit loss expectations along with prepayments. Discount
rates were developed based on the relative risk of the cash flows, taking into consideration the loan type, market rates as of
the valuation date, recent originations in the portfolio, credit loss expectations, and liquidity expectations. Lastly, cash
flows adjusted for credit loss expectations were discounted to present value and summed to arrive at the fair value of the
loans. Other loans were valued based on recent quotes, bids or recent sale prices of similar loans and for one loan portfolio
it was concluded the fair value equaled the portfolio's par value due to the short-term nature of the loan product, combined
with the low expected credit losses and the variable interest rates being at market.
Of the loans held for investment acquired, $3.0 billion were identified as PCD loans on the Merger date. The following
table provides a summary of these PCD loans at acquisition:

Mortgage servicing rights: The fair values of single family mortgage and SBA servicing rights are based on a market
approach, developed by a third party. The fair values of non-DUS multifamily and DUS servicing rights are based on a
market approach, developed by internal models. 
Premises and equipment: The fair values of premises are based on a market approach, by obtaining third-party appraisals
and broker opinions of value for land, office and branch space.
Other intangible assets: Core deposit intangibles assets of $90.8 million were recognized as a result of the Merger. Core
deposit intangible assets values were determined by an analysis of the cost differential between the core deposits inclusive
of estimated servicing costs and alternative funding sources for core deposits acquired through business combinations. The
core deposit intangible assets recorded are amortized on an accelerated basis over a period of 8 years. No impairment losses
separate from the scheduled amortization have been recognized in the periods presented.
Other intangibles acquired of $23.5 million related to a DUS license was recognized related to the Merger. The value of the
DUS licenses was determined by the average value implied under the Base and Growth scenarios using market data
available from comparable public companies.
Current and deferred tax assets, net: The acquired net tax assets represent the estimated amount of tax benefits to be
recognized on tax returns.
Deposits: The fair values used for the demand and savings deposits equal the amount payable on demand at the Merger
date. The fair values for time deposits are estimated using a discounted cash flow calculation that applies interest rates
currently being offered to the contractual interest rates on such time deposits.
Borrowings: The fair values of FHLB advances and long-term debt instruments are estimated based on quoted market
prices for the instrument if available, or for similar instruments if not available, or by using discounted cash flow analyses,
based on current incremental borrowing rates for similar types of instruments.
