Updating Summary Prospectus
May 1, 2026
This Summary Prospectus summarizes key features of the unallocated Group Combination Annuity Contract (the “Contract”) to provide retirement annuity benefits for self-employed persons and their eligible employees. Although the Contract is no longer offered for sale to retirement plans of self-employed persons, subsequent Purchase Payments may continue to be made under in-force Contracts. You may choose to invest your Net Purchase Payments on a variable, fixed, or a combination thereof on a tax-deferred basis.
The Prospectus for the Contract contains more information about the Contract, including its features, benefits, and risks. You can find the current Prospectus and other information about the Contract, including the annual and semi-annual reports for your underlying Portfolios, online at www.nmprospectus.com. You can also obtain this information at no cost by calling (866) 910-1232 or by sending an email request to [email protected].
Additional information about certain investment products, including variable annuity contracts, has been prepared by the Securities and Exchange Commission's staff and is available at www.Investor.gov.
The Securities and Exchange Commission (“SEC”) has not approved or disapproved the Contract or passed upon the adequacy of this Summary Prospectus. Any representation to the contrary is a criminal offense.
 
Glossary of Special Terms
Unless otherwise specified in this prospectus, the words “Northwestern Mutual,” “we,” “us,” “our,” and “Company” mean The Northwestern Mutual Life Insurance Company. The words “you” and “your,” unless otherwise specified, mean the Contract Owner. We use a number of special terms in this summary prospectus, including the following:
Accumulation Unit—An accounting unit of measure representing the Contract Value, before the date on which Annuity Payments begin, in one or more Divisions of the Separate Account. The related term “Accumulation Unit Value” (“AUV”) means the value of a particular Accumulation Unit at a particular time and is analogous to, but not the same as, the share price of a mutual fund.
Annuitant—The person upon whose life the Contract is issued and Contract benefits depend. The Primary Annuitant is the person upon whose life the Contract is initially issued. The Contingent Annuitant is the person who becomes the Annuitant upon the death of the Primary Annuitant. If the Contract is annuitized under a single life income plan, there will be one Annuitant. If the Contract is annuitized under a joint life income plan, there will be two Joint Annuitants.
Annuity Payments— Money we pay under a variable income plan or a fixed income plan during the annuitization phase of the Contract.
Annuity Unit—An accounting unit of measure representing the actuarial value of a variable income plan’s interest in a Division of the Separate Account after Annuity Payments begin.
Beneficiary— A person who receives payments under the Contract pursuant to an Income Plan or upon the death of the Annuitant before the Maturity Date provided that the Annuitant was an Owner of the Contract at the time of death.
Company—The Northwestern Mutual Life Insurance Company
Contract—The agreement between you and us described in this variable annuity prospectus. During the accumulation period of the Contract, you may invest money under your Contract and any earnings on your investment will accumulate on a tax-deferred basis. During the annuitization period, you receive periodic payments based largely on the amounts you accumulate, all or a portion of which will be taxable as ordinary income.
Contract Value—The value of your Contract on any Valuation Date is the sum of: (1) the value of your amounts held in the Divisions of the Separate Account on that Valuation Date; and (2) the sum of your amounts allocated to the Guaranteed Account(s), plus credited interest; less (3) any applicable fees and amounts withdrawn or transferred from the Guaranteed Account(s).
Division—A sub-account of the Separate Account, the assets of which are invested exclusively in the shares of one of the Portfolios of the underlying Funds.
Fund—A Fund is registered under the Investment Company Act of 1940 (the “1940 Act”) as an open-end management investment company or as a unit investment trust, or is not required to be registered under the 1940 Act. A Fund is available as an investment option under the Contract. The assets of each of the Divisions of the Separate Account are used to purchase shares of the corresponding Portfolio of a Fund.
General Account—All assets of the Company, other than those held in the Separate Account or in other separate accounts that have been or may be established by the Company.
Guaranteed Account—A fixed investment option under the Contract, supported by the assets held in the Company’s General Account, that has a term of a specified duration (called a “Guaranteed Period”).
Income Plan—An optional method of receiving the death benefit, maturity benefit, surrender proceeds or withdrawal proceeds of an insurance policy or annuity contract generally through a series of periodic payments. An Income Plan may also be known as a “payment plan.”
Market Value Adjustment—An amount that may be credited (or charged) to an amount withdrawn or transferred from a multi-year Guaranteed Account before the end of a Guaranteed Period.
Maturity Date—The date, stated on the specifications page of the Contract, on which Purchase Payments must cease and Annuity Payments become payable.
Northwestern Mutual—The Northwestern Mutual Life Insurance Company
Owner—The person with the sole right to exercise all rights and privileges under the Contract, except as the Contract otherwise provides.
Portfolio—A series of a Fund available for investment under the Contract which corresponds to a particular Division of the Separate Account.
Account C Prospectus

Prospectus— The full statutory prospectus for the Contract.
Purchase Payments—Money you give us to apply to your Contract. The related term “Net Purchase Payment” refers to Purchase Payments after all applicable deductions.
Required Minimum Distribution (“RMD”)—A minimum amount that the federal tax law generally requires be withdrawn from certain tax-qualified annuities each year.
Separate Account—The account the Company has established pursuant to Wisconsin law for those assets that, although belonging to the Company, are reserved for you and other owners of variable annuity contracts supported by the Separate Account.
Summary Prospectus—The summary version of the Contract, which summarizes key information found in the Prospectus for the Contract.
Valuation Date—Any day on which the New York Stock Exchange (“NYSE”) is open for trading and any other day we are required under the 1940 Act to value assets of a Division of the Separate Account.

Yes. Although you will not be assessed a surrender charge, a Market Value
Adjustment (“MVA”) may be assessed (or credited) on transfers, withdrawals,
surrenders, and annuitizations from a GRF (of any duration) prior to the
Maturity Date or before the end of the Guarantee Period.
 
A negative Market Value Adjustment will result in the loss of some or all
previously credited interest in excess of the minimum guaranteed annual
effective interest rate for the GRF, if any.
Fee and Expense

Because your Contract is customizable, the choices you make affect how much
you will pay. To help you understand the cost of owning your Contract, the
following table shows the lowest and highest cost you could pay each year,
based on current charges. This estimate assumes that you do not take
withdrawals from the Contract, which could add surrender charges and
negative Market Value Adjustments that substantially increase costs.
Although your actual costs may be higher or lower than those shown below,
based on these assumptions, your costs would be as follows:
 
LOWEST ANNUAL COST
$7541
HIGHEST ANNUAL COST
$4,1621
Assumes:
●Investment of $100,000
●5% annual appreciation
●Least expensive combination of Contract

RISKS
Cross-Reference(s)
to Location in
Prospectus
Is There a Risk of
Loss from Poor
Performance?
Yes. You can lose money by investing in the Contract.
The Investment
Options
Is This a Short-Term
Investment?
No. The Contract is not a short-term investment and is not appropriate for you
if you need ready access to cash. It is intended for retirement and long-term
savings.
 
A transfer, withdrawal, surrender, or annuitization from GRF prior to the
Maturity Date or end of a Guaranteed Period may result in a negative Market
Value Adjustment. A negative Market Value Adjustment will result in the loss of
some or all previously credited interest in excess of the minimum guaranteed
annual effective interest rate, if any.
 
Upon expiration of a Guaranteed Period for GRF, any amounts remaining in
that Guaranteed Account will be transferred to the Government Money Market
Division of the Separate Account, unless you instruct us to allocate the amounts
to the other Division(s) of the Separate Account of a new Guaranteed Period
for GRF.

The Contract –
Generally
What Are the Risks
Associated with the
Investment
Options?
Investment in the Contract is subject to the risk of poor investment
performance and can vary depending on the performance of the investment
options ( Portfolios) and fixed account options you choose. Each Portfolio
(including any fixed account investment options) will have its own unique risks.
You should review these investment options before making an investment
decision.
The Guaranteed Return Fund (GRF) accounts, fixed investment options offered
under the Contracts, are subject to the risk of negative Market Value
Adjustment (MVA) which could decrease the amount available for transfer or
withdrawal from a GRF account. You should carefully consider the effects of a
negative MVA before making a transfer or withdrawal from a GRF account.
The Investment
Options
What Are the Risks
Related to the
Insurance
Company?
Investment in the Contract is subject to the risks related to the Insurance
Company ( Northwestern Mutual), and any obligations (including under any
fixed account investment options), guarantees, or benefits are subject to the
claims-paying ability of Northwestern Mutual. More information about
Northwestern Mutual, including its financial strength ratings, is available upon
request by calling (888) 455-2232.

RESTRICTIONS
 
Are There
Restrictions on the
Investment
Options?
Yes. Transfer requests involving the fixed account options are subject to special
restrictions, including individual state law restrictions as to availability or
amounts. These options are available only during the accumulation phase of
your Contract and after your initial investment may be subject to limits on
additional amounts, including minimum required investments or maximum
limits on total amounts. Transfers out of these fixed options are also subject to
specific limitations, including charges, and monies moved out of these options
may limit the availability of any positive market value adjustment that might
otherwise apply.
Transfers among Divisions are subject to the Contract’s short-term and
excessive trading policies.
Under certain circumstances Northwestern Mutual reserves the right to
remove a Portfolio or substitute another Portfolio for such Portfolio.
